TL; DR.Mu gihe cy'imyaka 10, imigozi y'icyuma kitagira umugese ikunze gutsinda ku giciro cyose cyo gutunga imirima y'izuba yo hanze nubwo igiciro cyayo kiri hejuru inshuro 3-10 kuri buri gice. Intsinzi ya TCO ikomoka ku gukuraho abakozi basimbura - igice cy'ikiguzi cyiganje - no kwirinda gutsindwa mu gucunga insinga kubera imigozi ya nylon yangiritse. Ku murima wa megawati 100 ufite imigozi 200.000, TCO ya nylon y'imyaka 10 ni 400.000-800.000 by'amadolari y'Amerika; TCO y'icyuma kitagira umugese ingana na 150.000-300.000 by'amadolari y'Amerika. Aho uburinganire bugarukira biterwa n'ikirere (ubukana bwa UV, ubushyuhe), ikiguzi cyo kubungabunga, n'uburyo umukozi akurikirana imikorere ye.

Imigozi y'icyuma gifunganye - ni yo ikoreshwa mu kugereranya ubuhinzi bw'izuba mu myaka 10. Inkomoko: Xinjing Stainless Steel Co., Ltd.

Impamvu guhitamo imigozi y'insinga ari ikibazo cya TCO, atari ikibazo cy'ingenzi

Iyo itsinda rya EPC rishinzwe imirasire y'izuba risuzuma imigozi y'insinga kugira ngo ricunge imigozi ya DC, insinga ya AC ikora, n'insinga za homerun zikoreshwa na panel-to-inverter, icyemezo gikunze gutangirira ku kibazo cy'ibikoresho: nylon cyangwa icyuma kidashonga. Ikibazo gikurikiraho - ni ikihe gihendutse - ni ikibazo kitari cyo. Ikibazo gikwiye ni iki: mu gihe cy'imyaka 10 y'igishushanyo mbonera cy'umurima w'imirasire y'izuba, buri gikoresho gitwara iki muri rusange, harimo n'abakozi basimbura n'ikiguzi cy'imigozi yangiritse?

Kugira ngo dusubize icyo kibazo tukoresheje ibirenze ibyo kwamamaza gusa, twashyize hamwe ikiguzi cy'imyaka 10 cy'ubwishingizi bw'umutungo ugereranijeimigozi y'icyuma kitagira umugese(ubwoko bwa ball-lock, 304 na 316L) ugereranije n'imigozi isanzwe ya nylon ya PA66 (ifite imigozi ya UV ihamye kandi idahamye). Iyi moderi irimo ikiguzi cy'ibikoresho, inshuro zo gusimbuza, akazi ko gusimbuza, n'ikiguzi cyo guhomba kw'imigozi yangiritse ku ishashi ry'izuba rya MW 100. Iyi nkuru inyura mu buryo bw'icyitegererezo, ibice by'ikiguzi, n'isesengura ry'uburyo bwo guhomba.

Ibidukikije byo hanze byo kwibasirwa n'izuba mu murima

Ubuhinzi bw'izuba bwo hanze ni bumwe mu buryo bugoye bwo gucunga insinga. Insinga zihambira ku zuba ryinshi, zireba ubushyuhe bwose bw'umunsi, zihangana n'umucanga utwarwa n'umuyaga n'imvura, kandi mu turere tumwe na tumwe zihura n'ibyangiritse by'imbeba n'inyoni. Ibintu bine bibangamira ibidukikije bituma insinga zihambira ku zuba zigabanuka mu buhinzi bw'izuba ni ibi bikurikira:

• Imirasire ya UV.Polyamide (nylon) ni polymer y’umwimerere; UV igabanya imigozi ya amide uko igihe kigenda gihita, bigatuma urunigi rucika, imbaraga zo gukurura zigabanuka, ndetse amaherezo ikanananirwa gucika. Nayiloni y’umukara ifite UV-stabilized yongera igihe cyo gutsindwa ho 30-50% ariko ntikuraho uburyo bwo gutsindwa.
• Ihindagurika ry'ubushyuhe.Ubushyuhe bw'izuba ku zuba ryinshi ryo mu mpeshyi bugera kuri dogere selisiyusi 70-85 mu bihe by'ubushyuhe n'ubushyuhe bwa dogere selisiyusi 90 mu bihe by'ubutayu. Ubushyuhe bw'igihe cy'itumba mu turere dukonje bugabanuka bukagera kuri dogere selisiyusi -30 cyangwa munsi yabyo. Ihindagurika ry'ubushyuhe ngarukamwaka rishimangira buri polimeri n'ibyuma byinshi.
• Ubushuhe n'umunyu.Ahantu ho ku nkombe, imirasire y'izuba ireremba mu nyanja, n'ahantu ho mu turere dushyuha cyane, bituma insinga zifatwa n'ingese zitwarwa na chloride. Nayiloni ifata amazi igahindura ingano; icyuma gisanzwe cya 304 gishobora kwangirika mu miyoboro y'amazi mu bidukikije birimo chloride nyinshi.
• Ikoranabuhanga n'ibinyabuzima.Gutigita k'umuyaga, kwaguka k'ubushyuhe bw'umugozi, guhekenya imbeba (ibishishwa, imbeba), no kwangiza inyoni (cyane cyane mu gihe cyo gutera amagi y'inyoni) byose bishimangira umugozi mu buryo urupapuro rw'amakuru rudafata.

Ibintu bine bitera imbaraga bihurira hamwe. Ingufu ya nylon ikomeza kubaho imyaka 3 yanduye UV ishobora kunanirwa iyo itewe n'imbeba mu mwaka wa 4. Ingufu ya steel stainless ifata UV n'ubushyuhe nta kirego ishobora kwangirika ku gice cy'inyuma cy'urumuri mu kirere kirimo umunyu ku nkombe. Uburyo bwa TCO bugomba guhangana n'imbaraga zihuriweho, ntabwo ari urupapuro rw'amakuru gusa.

Imigozi y'Insinga Itagira Ingufu: Icyo ari cyo n'uko ikora

Imigozi y'icyuma kidapfa gushonga ikozwe neza mu gice cy'icyuma kidapfa gushonga gikonje, ubusanzwe gifite ubushobozi bwa 304 cyangwa 316L.ubwoko bw'umupira wifungiraikoresha umupira w'icyuma kitagira umugese ufatanywe mu mutwe ufunga; uko irangi rihambiriye, umupira wicara mu mwanya wo gufunga naho irangi rigafunga burundu. Irangi ntirishobora kongera gufungurwa ritaciwe, ari na yo myitwarire yifuzwa mu gucunga insinga z'imirasire y'izuba aho irangi ari kimwe mu bigize inzira y'insinga z'igihe kirekire.

Ingano zisanzwe z'ibikoresho bikoreshwa mu migozi y'amashanyarazi ikoreshwa n'izuba:

• Icyuma 304 kidasesagura.Igipimo cy'ingufu zikoreshwa mu gucukura ibidukikije byo mu gihugu imbere, ahantu hadakonje cyane. Ingufu zo gukurura ni 515-620 MPa bitewe n'ubukonje bukabije; ubushyuhe bwa serivisi buri hagati ya -80°C na +500°C buri gihe. 304 ni yo mahitamo ahendutse kandi akoreshwa mu gucukura ibyuma bikoresha imirasire y'izuba.
• Icyuma kitagira umwanda cya 316L.Uburyo bwo mu mazi bukoreshwa mu kurengera inkombe, ahantu hashyuha cyane, ndetse n'ahantu hose haherereye muri kilometero 5 uvuye aho inganda zikorera imiti. Ingano ya molybdenum 2-3% irushaho gutuma chloride idashobora kwangirika cyane. Ubusanzwe 316L ihenze cyane kurusha 30-50% ugereranyije na 304.
• Icyuma kitagira umwanda 201.Uburyo bwo gukoresha amafaranga make rimwe na rimwe bukoreshwa mu bintu bitari iby’ingenzi. Kurwanya ingese ni ukugabanya 304 kandi ntibisabwa gukoreshwa mu buhinzi bwo hanze bukoresha imirasire y’izuba.

Katalogi yacu ikubiyemo urutonde rwuzuye rwaimigozi y'icyuma kitagira umugesemu byiciro 200, 300, 400 by'uruhererekane n'ibice bibiri, hamwe n'uburyo bwo gushyiramo epoxy-coated na PVC-coated aho hakenewe ubundi buryo bwo kurinda ubushyuhe. Isomero rya Xinjing ry'ibikoresho bya stainless steel rinashyigikira icyuma kiri munsi yacyo (gikonje gifite ubugari bwa mm 0.03-3.0, ubugari bwa mm 10-600) kugira ngo gikoreshwe mu gukora insinga.

Imigozi ya Nylon: Icyo ari cyo n'uko inanirwa

Imigozi ya nylon — imigozi ya zip-booster ikoreshwa cyane n’amatsinda menshi ya EPC akoresha imirasire y’izuba — ikozwe muri polyamide 6.6 (PA66) hamwe n’umuti utuma imirasire ya UV idahinduka. Imigozi ikoresha iryinyo rya ratchet ry’inzira imwe rifunga burundu iyo rikozwe mu buryo bugoye kandi ntirishobora kongera gufungurwa ritaciwe. Imigozi isanzwe ya nylon irahendutse (0.05-0.30 USD kuri buri gice mu bwinshi), biroroshye kuyishyiraho, kandi ifite ibara ry’umuti urwanya imirasire ya UV.

Uburyo bwo gucika intege kw'imigozi ya nylon mu mirimo yo hanze yo guhinga hakoreshejwe imirasire y'izuba bwaragaragajwe neza:

1. Gukata urunigi ruterwa na UV.Imirasire ya UV igabanya imigozi ya amide iri mu mugongo wa polyamide. Ipfundo ritakaza imbaraga zo gukurura buhoro buhoro mu mezi menshi, hanyuma ritakaza uburebure vuba, hanyuma rigacika intege kandi rigacika intege mu gihe cy'umutwaro.
2. Ogisijeni y'ubushyuhe.Ubushyuhe bwihutisha kwangirika kwa ogisijeni kwa polyamide. Ahantu ho guhinga imirasire y'izuba hafite ubushyuhe bwinshi burambye, hangirika vuba kurusha ahantu hashyuha cyane.
3. Hydrolysis.PA66 ifata amazi (hafi 8-10% by'uburemere iyo yuzuye). Guhindagurika kw'amazi mu buryo bw'amazi mu buryo bw'ubushuhe bitera hydrolysis y'imigozi ya amide no gutakaza ubushobozi bwa mekanike.
4. Umunaniro uterwa n'imashini.Gutemba k'umuyaga, kwagura ubushyuhe bw'umugozi, n'uburyo bwo kuwukoresha mu kuwushyiraho byose bitanga umutwaro uhoraho. Ubushobozi bwa nylon bwo kudacika intege buri hasi ugereranyije n'imbaraga zayo zo gukurura zidahinduka.

Amabwiriza asanzwe y’inganda ni uko imigozi ya nylon mu murima ukoresha imirasire y’izuba hanze itakaza imbaraga zo gukurura 50% mu mezi 18-30 mu gihe cy’imirasire ya UV, hamwe no kwangirika burundu (kwangirika gukomeye) mu mwaka wa 4-6 bitewe n’ikirere. Uduce dushyuha cyane (Uburasirazuba bwo Hagati, Ositaraliya yo hagati, Amajyepfo y’Uburengerazuba bwa Amerika) twihutisha igihe; uturere dukonje dushobora kongera igihe. Nayiloni y’umukara ikoresha UV yongera igihe ku kigero cya 30-50%, ariko ntabwo ihuye n’igihe kirekire cy’icyuma kidashonga.

Uburyo bwa TCO bw'imyaka 10

Ku bijyanye na TCO, dukoresha ubuhinzi bw'izuba bwa MW 100 bufite insinga 200.000 mu ishyirwaho rya mbere. Ubu buryo bukubiyemo ibice bine by'ikiguzi: ibikoresho, ibikoresho byo gusimbuza, imirimo yo gusimbuza, n'ikiguzi cyo kwangirika. Ubu buryo bufata ko umukozi ayobora ubu buhinzi mu gihe cy'imyaka 10 yose y'igishushanyo mbonera hamwe n'uburyo bwo kongera gucunga insinga za DC n'insinga za AC mu mwaka wa 5.

Icyitegererezo kigaragaza ko imigozi y'icyuma kidashonga itsindira ku giciro cy'imyaka 10 cya TCO nubwo igiciro cy'ibikoresho ku giciro cya mbere kiri hejuru inshuro 3-10. Intsinzi ikomoka ku bice bitatu: gukuraho imirimo yo gusimbuza (igice cy'ikiguzi cyiganje), gukuraho ikiguzi cyo kwangirika (imigozi yangiritse ku miyoboro y'ingenzi), no gukuraho ikiguzi cyo guta mu gihe cy'ubuzima (icyuma kidashonga gishobora kongera gukoreshwa, nayiloni ijya mu myanda).

Igice cy'Ikiguzi cy'Ibikoresho

Igice cy'ikiguzi cy'ibikoresho ni cyo gikuru cy'amatsinda menshi ya EPC atangirana nacyo, kandi ni cyo gituma nylon isa n'aho ihendutse hejuru. Ku giciro cya 0.05-0.30 USD kuri nylon na 0.50-1.50 USD kuri buri giciro ku byuma bitanduye, ikintu cy'icyuma kitanduye gikoreshwa mu byuma bitanduye ni inshuro 3-10 z'ikintu cy'icyuma kitanduye ku giciro cya mbere cya 200.000-toy. Ku ifamu ya 100 MW, ni 100.000-300.000 USD ku byuma bitanduye ugereranyije na 10.000-60.000 USD kuri nylon.

Icyuho cy'ikiguzi cy'ibikoresho kirashira mu gihe cy'ubuzima bw'ibikoresho uko imigozi ya nylon isimbuzwa kandi ikiguzi cyo kuyisimbura kikiyongera. Mu mwaka wa 4-6, amafaranga yose yakoreshejwe muri nylon yamaze kurenga amafaranga yakoreshejwe mu byuma bita "stainless steel". Mu mwaka wa 10, amafaranga yose yakoreshejwe muri nylon akubye inshuro 3-5 z'amafaranga yose yakoreshejwe mu byuma bita "stainless steel", ndetse na mbere y'uko imirimo yongerwaho.

Imirimo yo gusimbuza: Igice cy'ingenzi cya TCO

Igice cy’umurimo wo gusimbuza ni cyo kintu kinini cyane mu buryo bwa TCO bw’imyaka 10. Gusimbuza insinga ku murima w’amashanyarazi ukoresha imirasire y’izuba bisaba ibikoresho byo kwinjira (icyiciro cya cherry cyangwa icyuma giterura imikasi), igihe cyo kujya aho icyuma cyangiritse, igihe cyo gusimbuza ubwacyo, n’igihe cyo gushyiraho. Igiciro cy’umurimo cyose ni hagati ya 1.5-3.5 USD kuri buri ngano iyo harimo ibikoresho byo kwinjira n’ingendo.

Insinga ubwayo ni 0.05-0.30 USD kuri nylon cyangwa 0.50-1.50 USD ku byuma bitarangwamo ifu.Ikiguzi cy'ibikoresho cya nylon kingana inshuro 5-10 kandi kingana n'igiciro cy'ibikoresho bya icyuma kitagira umugese.Igice cy'umurimo cya TCO ni cyo gituma igisubizo cy'ibikoresho byinshi gishobora gutsinda ku giciro cyose: gikuraho abakozi, ntabwo ari ibikoresho gusa.

Ku ruganda rwa megawati 100 rufite imigozi 200.000 n'indishi ya nayiloni 10% ku mwaka, ikiguzi cy'abakozi ku mwaka ni hagati ya 30.000 na 70.000 by'amadolari y'Amerika. Mu myaka 10, abakozi basimbura nayiloni bose hamwe ni hagati ya 300.000 na 700.000 by'amadolari y'Amerika. Ubuhinzi bumwe bufite imigozi ya sima itagira umugese n'indishi ya 0-1% ku mwaka bufite ikiguzi cy'abakozi cy'imyaka 10 kingana na 0-70.000 by'amadolari y'Amerika. Ishami ry'abakozi ryonyine ni hagati ya 230.000 na 630.000 by'amadolari y'Amerika mu rwego rwo hejuru rw'icyuma kitagira umugese.

Ikiguzi cyo gutsindwa: Ikintu cy'umurongo uhishe

Igice cy'ikiguzi cyo gutsindwa ni cyo kintu amakipe menshi ya EPC asuzugura. Insinga ya nylon yangiritse ntabwo igwa neza gusa - irekura insinga buhoro buhoro, bigatuma insinga igenda, igatera, ndetse amaherezo igacika intege. Uburyo bwo gutsindwa buturuka ku nsinga yangiritse mu murima ukoresha imirasire y'izuba burimo:

• Ikosa ry'ibanze.Insinga ya DC itakaza umugozi wayo igakorana n'umugozi cyangwa icyuma gifata icyuma gifunga icyuma gihindura inverter ikanahagarika umugozi kugeza igihe ikoreshejwe n'intoki.
• Ikosa ry'umusemburo.Ikoti rya DC ripfutse rigaragaramo karuvati irekuye rishobora kugira ikibazo cy’umugozi, ibyo bikaba bishobora guteza inkongi y’umuriro mu bimera byumye.
• Kwangirika kwa insinga.Gukomeza kugenda kw'agasanduku k'insinga kadafite umutekano ku gipfundikizo bikuraho ikoti kandi bikagaragaza kondakita.
• Ihungabana ry'umugozi.Umugozi uvanyweho cyangwa ufite ikibazo ugabanya umusaruro w'ubuhinzi kugeza igihe umugozi usimburanye n'insinga yongerewe gufatwa.

Igiciro cyatangajwe n'inganda cy'ikibazo cy'ikosa ry'imigozi imwe mu murima w'izuba ku rwego rw'inganda ni hagati ya 500-3.000 USD iyo ibintu byose birimo (igihe cyo gusuzuma, igice cyo gusimbuza, ikoreshwa ryatakaye, abakozi basana). Umurima ufite imigozi 200.000 ya nylon hamwe n'isimbura 10% ku mwaka ushobora kwitega ingaruka 30-80 z'ikosa ry'ubutaka cyangwa arc ku mwaka bivuye ku migozi yangiritse. Mu myaka 10, ikiguzi cy'ikosa ry'imigozi ya nylon ni hagati ya 50.000-150.000 USD; ku byuma bitarangwamo ibyuma, umubare ungana ni 0-15.000 USD.

Uburyo bwo guhangana n'ikirere: Impamvu ahantu hashyushye cyane n'aho ku nkombe hakunda ahantu hadakoreshejwe ibikoresho

Icyitegererezo cya TCO cy'imyaka 10 gishingiye ku miterere y'ikirere. Igipimo cyo gusimbuza nylon cya 8-15% ku mwaka ni impuzandengo y'akarere gashyuha; ahantu hashyushye kandi hakonje cyane n'ahandi ku nkombe hagaragara igipimo cyo hejuru. Igipimo cyo gusimbuza gishingiye ku miterere y'ikirere ni iki:

Icyitegererezo cya TCO cy'imyaka 10 mu turere dushyuha cyane gitanga icyuma kitagira umugese. Ku gipimo cya 15% ku mwaka cyo gusimbuza nylon, ikiguzi cy'abakozi ba nylon mu myaka 10 ni hagati ya 450.000-1.050.000 USD - kiri hejuru cyane ugereranyije n'ikiguzi cy'ibikoresho bya nylon biri hagati ya 100.000-300.000 USD. Ahantu ho mu turere dushyuha two ku nkombe z'inyanja haratangaje cyane: icyuma kitagira umugese cya 316L ni bwo buryo bwonyine bufatika ku bidukikije byo mu nyanja, kandi igipimo cyo gusimbuza nylon gituma nylon idakora neza mu buryo bunoze.

Inshuro zo gusimbuza: Umushoferi Utuje

Inshuro yo gusimbuza ni yo ituma moderi ya TCO ihagarara neza. Si yo nomero y'ibanze, ahubwo ni ikintu cy'ingenzi kigena niba igiciro cy'imyaka 10 gishingiye ku bikoresho cyangwa ku mirimo. Inshuro yo gusimbuza iterwa n'ibintu bitatu:

1. Ihungabana ry'ikirere.Imirasire y'izuba, ubwihindurize bw'ubushyuhe, n'ubushuhe byose byihutisha kwangirika kwa nylon. Inshuro zo gusimbuza ziri hagati ya 5% ku mwaka mu turere dukonje cyane kugeza kuri 22% ku mwaka mu turere dushyuha two ku nkombe z'inyanja.
2. Ubwiza bw'inyubako.Imigozi ya nylon ifunganye cyane inanirwa vuba kuko itangirana n'umuvuduko mwinshi w'imbere. Imigozi idafunganye ituma umugozi ugenda kandi ugatera ubukana. Ubuhanga bwo gushyiraho umugozi bukwiye ni ubuhanga bwo gushyiraho umugozi.
3. Uburyo bwo kubungabunga.Ahantu hatagerwa neza n’ibikoresho byo kubungabunga (izuba rireremba, ahantu ho mu misozi miremire, ahantu ho mu butayu kure) hatwara amafaranga menshi yo gusimbuza abakozi kuko ibikoresho byo kwinjira n’igihe cyo kugenda biba byinshi.

Ku bakoresha ubuhinzi bushingiye ku mirasire y'izuba bafite gahunda nziza zo kubungabunga no kubona serivisi nziza, igipimo cyo gusimbuza nylon gishobora kuba ku mpera nto y'urwego. Ku bakoresha ikoranabuhanga batinze cyangwa bafite ubushobozi buke bwo kuyibona, igipimo cyo gusimbuza kiri ku mpera nini cyangwa irenga. Uburyo bwa TCO bukoresha 10% nk'ahantu ho hagati harangwa n'ikirere gishyushye; abakoresha bagomba guhindura hashingiwe ku makuru yabo bwite yo kubungabunga.

Guhitamo ibikoresho: 304, 316L, cyangwa Epoxy-Coated

Guhitamo icyuma gikozwe mu buryo bwa "stainless steel" ni icyemezo cya kabiri cya TCO gituma TCO irushaho kuba nziza. Ku mbuga nyinshi zikoresha imirasire y'izuba mu gihugu, icyuma gikozwe mu buryo bwa "stainless steel" cya 304 ni cyo giciro gito kandi icyitegererezo cya TCO cy'imyaka 10 cyavuzwe haruguru gikoresha 304. Ku nkombe, ahantu harangwa n'ubushuhe bwinshi, cyangwa ahantu hakorerwa ingese, 316L ni yo ikoreshwa mu buryo bwa "marine" kandi ikiguzi cy'inyongera cya 30-50% cy'ibikoresho gikurwaho no kugabanya ikoreshwa rya "slag".

Ku bijyanye no gushyiraho aho ikoti ry'insinga rishobora kwangirika bitewe n'ibyangiritse bya mekanike, imigozi y'icyuma gikozwe muri epoxy cyangwa PVC yongeraho urwego rudahungabanya ubushyuhe. Ikoti ryongeraho 20-40% ku giciro cy'ibikoresho ariko rikuraho ibyago byo gukata insinga. Ku nsinga za DC zifite insinga zisanzwe za XLPE, 304 idatwikiriwe irahagije. Ku nsinga z'insinga zigoye (TPE, bimwe mu bikoresho bya PVC), epoxy-coated ni yo mahitamo yizewe.

Uburyo RFPs Nyayo zo mu murima w'izuba zigaragaza imigozi y'insinga

Impuguke ebyiri ziherutse gukusanya amakuru ku mikoreshereze y'izuba mu buhinzi bwacu zigaragaza uburyo guhitamo ibikoresho bigenda mu buryo bufatika:

4. Igipimo cy'ibidukikije.“Irinda imirasire ya UV, urwego rw’amazi yo mu mazi (ku nkengero z’inyanja), ubushyuhe buri hagati ya -40°C na +85°C byibuze.” Garagaza amanota y’ibidukikije kugira ngo urebe neza ko aho hantu hahurira hakwiranye n’imiterere y’aho hantu.

Ku bikoresho byombi, saba icyitegererezo cyo kugenzura mbere yo gushyiraho amabwiriza yose. Icyitegererezo kigomba kuba kirimo isuzuma ry’imbaraga zo gukurura (umugozi w’insinga ugomba gufata 80% by’umutwaro muto wo gukurura) no kugenzura amaso (nta busembwa bw’ubuso, nta minsi mikuru yo gupfuka ku migozi ipfuka). Ku bibanza by’ubuhinzi bw’izuba bifite imicungire y’insinga z’ingenzi, intambwe yo kugenzura ni yo gipimo cy’ingenzi cyane cya QC.

Kuramba no Kurangira kw'Ubuzima

Ibikoresho byombi bifite ibyo bishingiraho mu gihe cy’iherezo ry’igihe, ariko bitandukanye mu bunini. Icyuma kidashonga gishobora kongera gukoreshwa kandi ingano y’icyuma gishya kidashonga ubusanzwe iba iri hagati ya 60-90% (bitewe n’uwagikoze). Mu mpera z’igihe cy’imyaka 10, imigozi y’icyuma kidashonga ishobora kugaruzwa nk’ibisigazwa hanyuma igasubizwa mu ruhererekane rw’ibikoresho bidafite ibara ry’umutuku nta gihombo cy’ibikoresho.

Insinga za nylon zikunze kuzuzwa mu gihe cyo kurangira kw'izuba. PA66 ishobora kongera gukoreshwa mu buryo bwa tekiniki ariko ubukungu bwo gukusanya no gutunganya insinga nto zituruka mu murima ukoresha imirasire y'izuba ntabwo ari bwiza. Abakora akazi benshi bashyira insinga za nylon zakoreshejwe mu gukuraho imyanda.

Icyemezo cyo kurengera ibidukikije hagati y’icyuma kidashonga na nylon si cyo kintu cy’ingenzi gikoreshwa na TCO, ariko kigenda gikomeza kuba kimwe mu byemezo byo kugura ibikoresho ku bakoresha bafite amabwiriza ya ESG. Igiciro cyo kujugunya nylon (hafi 20.000 USD ku murima wa MW 100 mu myaka 10) ni ikintu gito, ariko ikigereranyo cya karuboni mu nzira yo kujugunyamo imyuka ni kimwe mu bigize Scope 3 yagutse, aho bamwe mu bakoresha bakurikirana.
