Igipfukisho c'izuba gishobora gutemba co gusanura amabara y'inyuma y'izuba yononekaye

Ishirahamwe ry’abashakashatsi ryo muri Tchèque-Otirishiya ryateguye umuti witwa polysiloxane gel ukora cane ushobora gusanasana neza ibipande vy’inyuma vy’ibikoresho vy’izuba vyasenyutse, ugasubizaho ubushobozi bwavyo bwo kwikingira umuriro no kwagura igihe c’ibikorwa vy’ibikoresho vy’amashanyarazi (PV) vyashaje. Uwo muti mushasha uratorera umuti ikibazo gikomeye gihanganye n’abakoresha amahinguriro y’izuba, kuko ugusenyuka kw’ibipande vy’inyuma-cane cane mu bice vyakozwe nko mu 2010-kenshi bituma habaho ivyiyumviro vy’umutekano n’ugutakaza cane ingufu.

Abashakashatsi bakoresheje umuti wihariye witwa polysiloxane gel, wateguwe ku bufatanye n’ishirahamwe ry’i Czech-rikora silikoni Siltech Solutions, rikoreshwa cane cane nk’igikoresho co gufasha mu gupfuka ibikoresho vy’amashanyarazi. Mu buryo butandukanye n’ibikoresho vya kera vyo gusanura bikomeye, abo bahinga barahinduye iyo gel kugira ngo ishobore gutemba neza, ivyo bikaba vyatumye ishobora kwuzuza mbere n’imivyimba mikeyi maze igakora igipande c’inyuma kitagira umurongo ku bipande vy’inyuma vyononekaye. Iryo gel rigizwe n’ivyuma vy’ivyuma vyitwa silicone-, bikomejwe n’ivyuma vyitwa silica fumed nk’ikintu co kwuzuza kugira ngo bikomeze gukomera, n’ikintu co gukiza ubukonje-bituma gikomera iyo gishikiwe n’ikirere n’ubukonje.

Abashakashatsi basiguye bati: “Igikorwa co gukira gitanguzwa n’ubukonje{0}}kiva ku ruhande kija hanze, buhoro buhoro iyo gel igakomera uko ubukonje bugenda burakwiragira mu kintu.” "Igihe iyo gel imaze gukira neza, ikora elastomer ishobora guhinduka ifise inkomezi nziza cane zo gukomera n'ubushobozi bwo kuramba, igatuma ishobora kwifatanya cane n'ibikoresho vyose vy'inyuma -mbere n'ivyo vyari vyarasenyutse canke bitari vyo ku ruhande." Ukwo kwifatanya ni ikintu gihambaye cane mu gukingira ubukonje kwinjira, ari co kintu nyamukuru gituma amabara y’inyuma yononekara kandi n’ivyo gukingira ivyuma ntibikore neza.

 

Igerageza ku bikoresho vy'inyuma

Igikoresho ca polysiloxane cageragejwe ubwa mbere ku bwoko butanu bw’ibikoresho vy’inyuma, vyerekana ubwoko bw’ibihimba vyakoreshejwe mu bikoresho vya PV mu myaka cumi iheze: co-extruded polyamide (AAA backsheet); ivyuma vy’ivyuma (PVF)-ivyuma bibiri vy’ivyuma; n’ibindi bihimba vy’umubiri (PVDF)-ivyo bihimba bibiri vy’umubiri; igikoresho co gutangura-gipfutse PET; n’ibindi bishasha vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma (ETFE)-. Ivyo bikoresho vyatowe kubera ko bikoreshwa cane kandi bikaba bizwi ko bishobora kwonona uko igihe kigenda kirarenga.

Ivyitegererezo vy’umurongo w’inzira (ubwaguke bwa 3cm, uburebure bwa 12cm) vyaciwe ku bwoko bumwe bumwe bw’igipapuro c’inyuma, hanyuma iyo gel ishirwa ku ruhande rw’umuyaga-rwagaragara rw’uruzitiro rumwe rumwe. Iryo tsinda ryavuze ko “Igipande ca kabiri c’inyuma, uruhande rw’umuyaga ruri hasi, cashizwe hejuru y’ico gipimo cari gipfutse n’ibara ry’agahama, hanyuma kirakandanywa buhoro buhoro kugira ngo kibe igipande c’ibara ry’agahama gifise uburebure bumwe bw’iminota 1,2.” "Ivyo bihimba vy'umubiri birenze urugero vyakuwe ku mpande, maze ivyo bipimo birakira ku bushuhe bwa degre 25 n'ubukonje bwa 55% mu kiringo c'imisi 30. Inyuma yo gukira, ivyo bipimo vyashizwe mu gukura vyihuta mu cumba c'ikirere ku bushuhe bwa degre 85 n'ubukonje bwa 85% mu kiringo c'imisi1. amasaha-igerageza ry'uburemere bw'ibice vya PV."

Isesengura ry’inyuma- ryerekanye ko iyo gel yerekanye ukwifatanya kudasanzwe ku bwoko bwose butanu bw’ibipande vy’inyuma, n’ukunanirwa kw’ubumwe 100% kwabonetse muri buri nkuru. Ivyo vyerekana ko ubucuti buri hagati y’ivyo bihimba vy’umubiri n’ivyo bihimba vy’umubiri vyari bikomeye kuruta ivyo bihimba vy’umubiri ubwavyo, ivyo bikaba vyemeza ko bishobora kwizigirwa igihe kirekire- kandi ko bishobora guhangana n’ugusenyuka.

 

Igerageza ku bipande vy'imyaka umunani-vyasenyutse

Inyuma y’aho, iyo gel yarageragejwe ku bikoresho vya PV vyashaje bifise amabara y’inyuma ya AAA yari amaze imyaka umunani akora kandi yerekanye ibimenyetso bikomeye vy’ugusenyuka, harimwo n’imivyimba myinshi y’uburebure hejuru y’ibipande vy’amabisi y’ingingo n’ugusenyuka kw’imbere. Ico gipfukisho cari gica mu binogo hakoreshejwe igikoresho co gukingira, hanyuma kigashirwa mu buryo buringaniye ku ruhande rwose rw’inyuma rw’igipande hakoreshejwe igikoresho cagutse kugira ngo gikore igipfukisho co kugikingira. Ivyo bihimba vyari vyasanuwe vyaciye bishirwa mu cumba kimwe c’ikirere, bimara amasaha 1.000 bikoreshwa n’ubushuhe butoshe.

Ivyo bipimo vyafashwe inyuma y’ugukura vyerekanye ko imivyimba yari yapfutse neza kandi ko itagiboneka, kandi ko izo module zasanuwe zashitse ku mibare y’ubushobozi bwo gukingira umuriro iri hejuru ya 200 MΩ-irengeye neza ibisabwa kugira ngo izo module zikore neza. Abashakashatsi bavuze bati: “N’inyuma y’ikigeragezo c’ubushuhe bw’amazi, ivyo bikoresho vyagumye bifise ubushobozi bwo kwikingira kandi vyaciye mu kigeragezo c’ugusohoka kw’amazi ata bimenyetso vy’uko ubukonje bwinjiye.” Ivyo vyemeza ubushobozi bw’iyo gel bwo kugarura ibipimo vy’umutekano n’ubushobozi bihambaye mu bice vy’ugukura.

 

Igerageza ku ruganda rw'izuba rukora

Kugira ngo bemeze ko ibikorwa vy’isi vy’ukuri-bikora, abo bashakashatsi bashize mu ngiro ubuhinga bwo gusanura uruganda rw’izuba rukoresha 10MW muri Repubulika ya Tchèque, aho ibice vyinshi vyari vyarasenyutse. Iryo tsinda ryashimikiye ko "Ico gikoresho ca polysiloxane cashizwe mu murima ata gusenyura ibice-vyatanzwe bivuye ku gitereko co mu minwe, hanyuma bigasenyerwa ku ruhande rw'inyuma rw'igitabu hakoreshejwe igikoresho co gusenyura." "Ivyo bikoresho vyasanuwe vyasigaye bikora mu bihe vy'isi mu kiringo c'amezi atatu, bifise ubushuhe butandukanye, ubukonje n'imishwarara ya UV."

Ivyigwa vy’ugusohoka kw’amazi vyakozwe inyuma y’igerageza ryo mu murima vyemeje ko izo module zasanuwe zagumye zifise ubushobozi bwo kwikingira kandi zikora neza, ata n’inguvu zigabanutse ugereranyije n’izo module zitarononekaye. Abashakashatsi bavuze ko iyo gel ishobora gutuma ibikorwa vyayo biguma bimeze neza, naho nyene bikenewe ko igerageza igihe kirekire mu myaka myinshi kugira ngo umuntu asuzume neza ko ishobora gukomera. "Ikibazo nyamukuru gisigaye ni nimba urupapuro rw'inyuma rwasanuwe rushobora guhura n'ubushobozi bw'igihe kirekire bw'intambamyi y'ubukonje, cane cane mu turere dufise ibihe bikomeye cane."

Ubushakashatsi bwasohowe mu kinyamakuru "Igikoresho co gusanura polysiloxane gel ku bipande vy'inyuma vy'ibikoresho vy'amashanyarazi vyasenyutse" mu kinyamakuru c'ubushakashatsi ku bikoresho vy'amashanyarazi. Iryo tsinda ry’ubushakashatsi ryari rigizwe n’abahinga bo muri Siltech Solutions Czech Republic, Ikigo c’ubushakashatsi co muri Otirishiya ku vyerekeye ubuhinga bwa shimi n’ubuhinga (OFI), na Kaminuza y’ubuhinga ya Czech i Prague-bubaka ku nguvu z’ubufatanye zo gutegura inyishu z’ugucungera amashanyarazi y’umuyagankuba zitazimvye kandi ziramvye.
