I-XLPO vs XLPE vs PVC: Iingenelo zokusebenza kunye neemeko zokusetyenziswa kwiintambo ze-Photovoltaic

Umbane ozinzileyo nofanayo awuxhomekekanga kuphela kwizakhiwo zomqhubi osemgangathweni ophezulu kunye nokusebenza, kodwa nakwimigangatho yezinto ezimbini ezibalulekileyo kwintambo: i-insulation kunye nezinto ze-sheath.

Kwiiprojekthi zamandla zokwenyani, iintambo zihlala zichatshazelwa ziimeko zokusingqongileyo ezinzima kangangexesha elide. Ukususela ekuchatshazelweni yi-UV ngqo, imililo yezakhiwo, ukungcwatywa komhlaba, ukubanda okukhulu, ukuya kwimvula enkulu, zonke ezi zinto zibangela imingeni kwizinto zokukhusela kunye nezigcina ubushushu zeentambo ze-photovoltaic. Izinto ezisetyenziswa kakhulu ziquka i-cross-linked polyolefin (XLPO), i-cross-linked polyethylene (XLPE), kunye ne-polyvinyl chloride (PVC). Zonke ezi zinto zineempawu ezahlukeneyo ezifanelekileyo kwiimeko ezahlukeneyo zokusingqongileyo kunye neemfuno zeprojekthi. Zithintela ngempumelelo ukulahleka kwamandla kunye neesekethe ezimfutshane, kwaye zinciphisa iingozi ezifana nomlilo okanye ukutshayiswa kombane.

I-PVC (iPolyvinyl Chloride):
Ngenxa yokuguquguquka kwayo, ixabiso eliphakathi, kunye nokulula kokucutshungulwa kwayo, i-PVC ihlala iyinto eluhlaza esetyenziswa kakhulu ekugqumeni iintambo kunye nokugquma. Njengezinto ze-thermoplastic, i-PVC inokubunjwa ngokulula ibe ziimo ezahlukeneyo. Kwiinkqubo ze-photovoltaic, idla ngokukhethwa njengezinto ze-sheath, inika ukhuseleko lokukrala kwii-conductors zangaphakathi ngelixa inceda ukunciphisa uhlahlo-lwabiwo mali lweprojekthi iyonke.

I-XLPE (iPolyethylene edityanisiweyo):
Eziveliswe kusetyenziswa inkqubo yobungcali yokudibanisa i-silane cross-linking, ii-silane coupling agents zifakwa kwi-polyethylene ukomeleza amandla kunye nokumelana nokuguga. Xa zisetyenziswa kwiintambo, olu lwakhiwo lwe-molecular luphucula kakhulu amandla oomatshini kunye nozinzo, luqinisekisa ukuqina phantsi kweemeko zemozulu ezimbi kakhulu.

I-XLPO (i-Cross-linked Polyolefin):
Ziveliswa ngenkqubo ekhethekileyo yokudibanisa imitha, ii-polymers ezithe ngqo ziguqulwa zibe zii-polymers ezisebenzayo eziphezulu ezinesakhiwo senethiwekhi esinemilinganiselo emithathu. Inika ukumelana okuhle kakhulu kwe-UV, ukumelana nobushushu, ukumelana nokubanda, kunye neempawu zoomatshini. Ngokuguquguquka okukhulu kunye nokumelana nemozulu kune-XLPE, kulula ukuyifaka kunye nokuhambahamba kwiindlela ezintsonkothileyo—okwenza ukuba ifaneleke ngakumbi kwiiphaneli zelanga eziphahleni okanye kwiinkqubo ze-array ezifakwe emhlabeni.

I-XLP compound yethu yeentambo ze-photovoltaic ihambelana neRoHS, REACH, kunye neminye imigangatho yokusingqongileyo yamazwe ngamazwe. Ihlangabezana neemfuno zokusebenza ze-EN 50618:2014, TÜV 2PfG 1169, kunye ne-IEC 62930:2017, kwaye ifanelekile ukusetyenziswa kwi-insulation kunye ne-sheath layers zeentambo ze-photovoltaic. Le nto iqinisekisa ukhuseleko lokusingqongileyo ngelixa inikezela ngokuhamba kakuhle kokucubungula kunye nomphezulu ogudileyo wokukhupha, iphucula ukusebenza kakuhle kokwenziwa kweentambo kunye nokuhambelana kwemveliso.

Ukumelana nomlilo namanzi
I-XLPO, emva kokufakelwa imitha, ineempawu zokungatshisi ilangabi. Igcina uzinzo phantsi kobushushu obuphezulu kunye noxinzelelo, inciphisa kakhulu umngcipheko womlilo. Ikwaxhasa ukumelana namanzi okulinganiselwe yi-AD8, okwenza ukuba ifaneleke kwiindawo ezifumileyo okanye ezinemvula. Ngokwahlukileyo koko, i-XLPE ayinayo i-iron flame resistant kwaye ifanelekile ngakumbi kwiinkqubo ezifuna ukumelana namanzi ngamandla. Nangona i-PVC inamandla okuzicima, ukutsha kwayo kunokukhupha iigesi ezintsonkothileyo.

Ubuthi kunye nempembelelo kwindalo esingqongileyo
I-XLPO kunye ne-XLPE zombini zizinto ezingenayo i-halogen, ezingatshisi kakhulu, ezingakhuphi igesi ye-chlorine, ii-dioxins, okanye inkungu ye-asidi erhabaxa ngexesha lokutsha, nto leyo enika ubungane ngakumbi nokusingqongileyo. I-PVC, kwelinye icala, inokukhupha iigesi eziyingozi ebantwini nakwindalo xa kushushu kakhulu. Ngaphezu koko, izinga eliphezulu lokudibanisa i-XLPO liyinika ubomi obude benkonzo, nto leyo enceda ekunciphiseni iindleko zokutshintshwa kunye nokugcinwa kwexesha elide.

I-XLPO kunye ne-XLPE
Imeko yokusetyenziswa: Izikhululo zamandla elanga ezinkulu kwiindawo ezinelanga elinamandla okanye imozulu erhabaxa, uphahla lwelanga lwezorhwebo nolwemizi-mveliso, ii-solar arrays ezifakwe emhlabeni, iiprojekthi ezimelana nokugqwala phantsi komhlaba.
Ukuguquguquka kwazo kuxhasa uyilo oluntsonkothileyo, njengoko iintambo kufuneka zihambe kwimiqobo okanye zihlengahlengiswe rhoqo ngexesha lokufakwa. Ukuqina kwe-XLPO phantsi kweemeko zemozulu ezimbi kuyenza ibe lukhetho oluthembekileyo kwiindawo ezinokuguquguquka kobushushu kunye neendawo ezinobungozi. Ingakumbi kwiiprojekthi ze-photovoltaic ezineemfuno eziphezulu zokuthintela ilangatye, ukhuseleko lokusingqongileyo, kunye nobude bexesha, i-XLPO ivelele njengesixhobo esithandwayo.

I-PVC
Imeko yokusetyenziswa: Ukufakelwa kwelanga ngaphakathi, iinkqubo zelanga ezifakwe umthunzi eluphahleni, kunye neeprojekthi kwiindawo ezinemozulu epholileyo apho ukukhanya kwelanga kungangeni kakhulu.
Nangona i-PVC ine-UV ephantsi kunye nokumelana nobushushu, isebenza kakuhle kwiindawo ezibonakala kancinci (ezifana neenkqubo zangaphakathi okanye iinkqubo zangaphandle ezinombala omncinci) kwaye inika ukhetho olungabizi kakhulu.
