Ingabe akhona amazinga kazwelonke noma amazwe ngamazwe wesikhwama se-EVAukuhlolwa kwekhwalithi?
Izikhwama ze-EVA, okungukuthi, izikhwama ezenziwe nge-ethylene-vinyl acetate copolymer (EVA), zisetshenziswa kabanzi emikhakheni ehlukahlukene ngenxa yokukhanya kwazo, ukuqina nokusebenza okuhle kokugoba. Ukuze kuhlolwe ikhwalithi yezikhwama ze-EVA, kukhona ngempela uchungechunge lwezindinganiso zikazwelonke nezamazwe ngamazwe ukuqinisekisa ukuphepha nokuthembeka kwemikhiqizo. Nazi ezinye izindinganiso ezibalulekile zokuhlola ikhwalithi yesikhwama se-EVA:
Amazinga Omhlaba
I-ISO 1629-1: Leli indinganiso yendlela yokuhlola yezinto ze-EVA ezakhiwe yi-International Organisation for Standardization (ISO), emboza ukuhlolwa kwempahla ebonakalayo yezinto ze-EVA, njengamandla aqinile, ubude ngesikhathi sekhefu, njll.
I-ASTM D1043: Izinga lempahla ye-EVA elathuthukiswa yi-American Society for Testing and Materials (ASTM), elihlanganisa izindlela zokuhlola impahla ebonakalayo yezinto ze-EVA
Amazinga Kazwelonke

I-GB/T 29848-2018: Icacisa izidingo, izindlela zokuhlola, imithetho yokuhlola, ukumaka, ukupakisha, ukuthutha nokugcinwa kwamafilimu e-ethylene-vinyl acetate copolymer (EVA) ye-photovoltaic module encapsulation
I-GB/T 27934.2-2011: Ukulawulwa kwenqubo kanye nezindlela zokuhlonza ze-laminating ephepheni eliphrintiwe Ingxenye 2: I-Ethylene-vinyl acetate copolymer (EVA) hot melt adhesive pre-coating film
I-GB/T 31984-2015: Indlela yokuhlola yokuqukethwe kwe-vinyl acetate ku-ethylene-vinyl acetate copolymer yamamojula we-photovoltaic Ukuhlaziywa kwe-Thermogravimetric (TGA)
Izindinganiso zezimboni
I-HG/T 2877: Izinga lemboni yamakhemikhali, elibandakanya inqubo yokukhiqiza kanye nezidingo zekhwalithi yomkhiqizo wezinto ze-EVA
I-QB/T 2309: Izinga lemboni ekhanyayo, elibandakanya izinga lokusetshenziswa kwezinto ze-EVA ezintweni zezicathulo
Izindinganiso zokuvikela imvelo
I-RoHS Directive: Umkhawulo wokusetshenziswa kwezinto ezithile eziyingozi kumishini kagesi neye-elekthronikhi, ukusetshenziswa kwezinto ze-EVA kumishini kagesi kudinga ukuthobela lo myalelo.
I-REACH Regulation: Imithetho ye-EU yokubhaliswa, ukuhlolwa, ukugunyazwa kanye nemikhawulo yamakhemikhali, ukukhiqizwa nokusetshenziswa kwezinto ze-EVA kudingeka kuhambisane nezidingo Zomthethonqubo we-REACH.
Izidingo zokusebenza nezindlela zokuhlola
Izidingo zokusebenza zezinto ze-EVA ngokuvamile zihlanganisa izakhiwo ezibonakalayo, izakhiwo ezishisayo, izakhiwo zamakhemikhali kanye nokuvumelana nezimo zemvelo. Izindlela zokuhlola zifaka ukuhlolwa okuqinile, ukuhlolwa kokuqina, ukuhlolwa kokuguqulwa okungapheli kokucindezelwa kanye nokuhlolwa kokuhlaziya okushisayo, njll.
Ngokulandela lezi zindinganiso, ukukhiqizwa nokusetshenziswa kwezikhwama ze-EVA kungaqinisekisa ikhwalithi nokuphepha kwazo futhi kuhlangabezane nezidingo zezimakethe ezahlukene nezindawo zokufaka izicelo. Lawa mazinga awagcini nje ngokuhlanganisa ukuhlolwa kokusebenza komzimba okuyisisekelo kwezinto ze-EVA, kodwa futhi ahlanganisa ukuvikelwa kwemvelo kanye nezidingo eziqondene nomkhakha, ezinikeza isiqinisekiso esiphelele sekhwalithi yezikhwama ze-EVA.
Incazelo eyengeziwe:
Yiziphi izidingo eziyinhloko ze-GB/T 29848-2018?
I-GB/T 29848-2018 iyindinganiso kazwelonke yaseShayina, ebeka ngokuyinhloko izidingo, izindlela zokuhlola, imithetho yokuhlola, ukumaka, ukupakisha, ukuthutha nokugcinwa kwamafilimu e-ethylene-vinyl acetate copolymer (EVA) ukuze kuhlanganiswe imojula ye-photovoltaic. Okulandelayo ezinye zezidingo eziyinhloko ezishiwo ezingeni:
Ububanzi bokusebenza: Leli zinga lisebenza kumafilimu e-EVA e-photovoltaic module encapsulation, futhi icacisa amafilimu e-EVA asobala namafilimu e-EVA amhlophe.
Imigomo nezincazelo: Kwengezwe imigomo nezincazelo zamafilimu e-EVA abonisa ngale, amafilimu e-EVA amhlophe, nokuminyana kwendawo, futhi kwasusa imigomo nezincazelo zamafilimu e-EVA, i-crosslinking degree, nezinga lokuncipha.
Izidingo zokucaciswa: Kulungiswe izimfuneko zokucaciswa, kuhlukaniswe ngokucaciswa kwe-EVA esobala kanye nokucaciswa kwe-EVA emhlophe, kanye nokuchezuka kwe-surface density yengezwe.
Izidingo zokubukeka: Kwengezwe izimfuneko zokuthi “akukho ama-creases namabala”
Izidingo zokusebenza komzimba: Kwengezwe izidingo zokusebenza komzimba we-EVA esobala, kulungiswe indlela yokudlulisa, amandla ekhasi, ukumelana nevolumu, ukumelana nokuguga kwe-UV, izinga lokushisa eliphezulu nokusebenza okunomswakama ophezulu ukuguga, futhi kwashintsha amandla kagesi okuphuka abe namandla kagesi, kwengeza amandla aqinile, ubude. ngesikhathi sekhefu, inkomba yokumelana nokulandelela, ukusebenza kokuguga kokushisa okomile (into ozikhethela yona), izinga lokushisa eliphezulu le-UV kanye nokusebenza kokuguga komswakama ophezulu (into ozikhethela yona), ukusebenza kokuguga kwe-PCT (into ozikhethela yona)
Izimo zokuhlola: Shintsha "izimfuneko zesampula" zibe "Izimo zokuhlola" Izingxenye", futhi ulungise izidingo ezifanele
Izindlela zokuhlola: kulungiswe indlela yokuhlola ukujiya, yengeza indlela yokuhlola ukuminyana kobuso; ulungise indlela yokuhlola ukubukeka; wengeze indlela yokuhlola ukuminyana kobuso; isuse indlela yokuhlola okuqukethwe kwe-vinyl acetate (VA); uguqule indlela yokuhlola yokudlulisela; wengeze indlela yokuhlola i-reflection; uguqule indlela yokuhlola idigri ye-crosslinking; wanezela amandla aqinile kanye nobude ezindleleni zokuhlola ikhefu; uguqule indlela yokuhlola amandla e-peel; ulungise indlela yokuhlola ukushwabana; uguqule indlela yokuhlola amandla kagesi; wengeze indlela yokuhlola inkomba yokumelana nokulandela umkhondo; iguqule indlela yokuhlola ukumelana nokuguga kwe-UV; iguqule izinga lokushisa eliphezulu kanye nomswakama ophezulu wokuhlola indlela yokusebenza yokuguga; ingeze ukusebenza kokuguga kokushisa okomile, izinga lokushisa eliphezulu le-UV kanye nokusebenza kokukhula komswakama ophezulu, izindlela zokuhlola ukusebenza kokuguga kwe-PCT
Imithetho yokuhlola: yengeza “imininingwane nokuchezuka” ezintweni zokuhlola zasefekthri; ulungise uhlobo lokuhlola
Ukupakisha, ezokuthutha kanye nesitoreji: kuguqule impilo yeshalofu yomkhiqizo ngemva kokuvulwa kwebhokisi lokupakisha
Le mithethonqubo iqinisekisa ukusebenza kanye nekhwalithi yefilimu ye-EVA ku-photovoltaic module encapsulation ukuze kuhlangatshezwane nezidingo zemboni ye-photovoltaic.
Yiziphi izinto zokuhlola ezifakwe kuzinga le-ASTM D1043?
Izinga le-ASTM D1043 ikakhulukazi libandakanya ukuhlolwa kwe-torsion yezinto zepulasitiki ngaphansi kwezinguquko zokushisa ukuze kutholakale izici zokuqina kwazo. Okulandelayo ezinye zezinto zokuhlola ezifakwe kuzinga le-ASTM D1043:
Ukuqina kwe-Torsional: Ukuhlola ukuqina kwe-torsional yezinto zepulasitiki emazingeni okushisa ahlukene, okuyipharamitha ebalulekile yokukala ikhono lempahla lokumelana ne-torsional deformation.
Ukuncika kwezinga lokushisa: Ukuhlola ukuthi ukuqina kwe-torsional kwezinto zepulasitiki kushintsha kanjani nezinga lokushisa, okubalulekile ekuqondeni ukusebenza kwezinto ngaphansi kwezimo ezehlukene zemvelo.
I-Torsional creep: Ukulinganisa ukuguquguquka kokuguquguquka kwezinto zepulasitiki ngokuhamba kwesikhathi ngaphansi kwe-torque engaguquki ukuze kuhlolwe ukuzinza kwesikhathi eside kwento.
Ukuphumula kwe-Torsional: Ukuhlola i-torque yezinto zepulasitiki ngaphansi kokuguqulwa kwe-torsional njalo ngokuhamba kwesikhathi ukuze uqonde izici zokuphumula zokucindezeleka zezinto ezibonakalayo.
Izinga le-ASTM D1043 lihlinzeka ngendlela yokuhlola lezi zinkomba zokusebenza kwezinto zepulasitiki ngokuhlolwa kwe-torsion, okubaluleke kakhulu mayelana nokukhethwa kwezinto ezibonakalayo, ukwakheka komkhiqizo nokulawulwa kwekhwalithi. Ngalezi zinto zokuhlola, ukuthembeka nokuqina kwezinto zepulasitiki ezinhlelweni ezihlukahlukene zingaqinisekiswa.
