Kuki gukora insinga za Photovoltaque ari ngombwa?Intsinga ya Photovoltaque ikunze guhura nizuba, kandi ingufu zizuba zikoreshwa mubihe bidukikije bikabije, nkubushyuhe bwinshi nimirasire ya ultraviolet.Mu Burayi, iminsi yizuba izatera ubushyuhe bwaho ingufu zizuba zikagera kuri 100 ° C.
Kugeza ubu, ibikoresho bitandukanye dushobora gukoresha birimo PVC, reberi, TPE hamwe n’ibikoresho byo mu rwego rwo hejuru bihuza, ariko ikibabaje ni uko insinga za reberi zapimwe kuri 90 ° C ndetse n’insinga za PVC zapimwe kuri 70 ° C zikoreshwa kenshi hanze.Kugirango uzigame ibiciro, abashoramari benshi ntibahitamo insinga zidasanzwe zikoresha ingufu zizuba, ahubwo bahitamo insinga zisanzwe za PVC kugirango basimbuze insinga zifotora.Biragaragara, ibi bizagira ingaruka cyane mubuzima bwa serivisi ya sisitemu.
Ibiranga insinga za Photovoltaque bigenwa nubushakashatsi bwihariye bwihariye hamwe nibikoresho byibyatsi, ibyo twita guhuza PE.Nyuma yo kuraswa nihuta ryihuta, imiterere ya molekulire yibikoresho bya kabili izahinduka, bityo itange imikorere yayo itandukanye.
Kurwanya imizigo yubukanishi Mubyukuri, mugihe cyo kuyishyiraho no kuyitunganya, insinga zirashobora kunyuzwa kumpande zikarishye zubatswe hejuru yinzu, kandi insinga zigomba kwihanganira igitutu, kunama, guhagarika umutima, imitwaro yambukiranya imipaka n'ingaruka zikomeye.Niba umugozi wa kabili udakomeye bihagije, insinga ya insulasiyo yangiritse cyane, bityo bikagira ingaruka kumibereho yumurimo wa kabili yose, cyangwa bigatera ibibazo nkumuzunguruko mugufi, umuriro no gukomeretsa umuntu.
