Na ho na le litekanyetso tsa naha kapa tsa machabeng bakeng sa mokotla oa EVAtlhahlobo ea boleng?
Mekotla ea EVA, ke hore, mekotla e entsoeng ka ethylene-vinyl acetate copolymer (EVA), e sebelisoa haholo libakeng tse fapa-fapaneng ka lebaka la bobebe ba eona, nako e telele le ts'ebetso e ntle ea cushioning. Bakeng sa tlhahlobo ea boleng ba mekotla ea EVA, ehlile ho na le letoto la litekanyetso tsa naha le tsa machabeng ho netefatsa polokeho le ts'epahalo ea lihlahisoa. Mona ke litekanyetso tse ling tsa bohlokoa tsa tlhahlobo ea boleng ba mokotla oa EVA:
Melao ea Machaba
ISO 1629-1: Ena ke tekanyetso ea mokhoa oa liteko bakeng sa lisebelisoa tsa EVA tse ntlafalitsoeng ke Mokhatlo oa Machabeng oa Boemo (ISO), o koahelang liteko tsa thepa ea 'mele ea lisebelisoa tsa EVA, joalo ka matla a thata, bolelele nakong ea khefu, jj.
ASTM D1043: Tekanyetso ea thepa ea EVA e ntlafalitsoeng ke Mokhatlo oa Amerika oa Teko le Lisebelisoa (ASTM), e koahelang mekhoa ea tlhahlobo ea thepa ea 'mele ea thepa ea EVA.

Melao ea tšireletso ea tikoloho
Tataiso ea RoHS: Thibelo ea ts'ebeliso ea lintho tse ling tse kotsi lisebelisoa tsa motlakase le tsa elektroniki, ts'ebeliso ea lisebelisoa tsa EVA lisebelisoa tsa elektroniki li hloka ho latela taelo ena.
REACH Regulation: Melao ea EU mabapi le ngoliso, tlhahlobo, tumello le thibelo ea lik'hemik'hale, tlhahiso le ts'ebeliso ea lisebelisoa tsa EVA li hloka ho latela litlhoko tsa REACH Regulation.
Litlhoko tsa ts'ebetso le mekhoa ea tlhahlobo
Litlhoko tsa ts'ebetso ea lisebelisoa tsa EVA hangata li kenyelletsa thepa ea 'mele, thepa ea mocheso, thepa ea lik'hemik'hale le maemo a tikoloho. Mekhoa ea liteko e kenyelletsa tlhahlobo ea tensile, teko ea boima, tlhahlobo ea deformation e sa feleng ea compression le tlhahlobo ea tlhahlobo ea mocheso, jj.
Ka ho latela litekanyetso tsena, tlhahiso le tšebeliso ea mekotla ea EVA e ka netefatsa boleng ba bona le polokeho le ho finyella litlhoko tsa limmaraka tse fapaneng le libaka tsa kopo. Litekanyetso tsena ha li akaretse feela liteko tsa mantlha tsa ts'ebetso ea 'mele ea lisebelisoa tsa EVA, empa hape li kenyelletsa ts'ireletso ea tikoloho le litlhoko tse ikhethileng tsa indasteri, tse fanang ka tiisetso e felletseng ea boleng ba mekotla ea EVA.
Tlhaloso ea tlatsetso:
Ke litlhoko life tse ka sehloohong tsa GB/T 29848-2018?
GB/T 29848-2018 ke tekanyetso ea naha ea Chaena, eo haholo-holo e hlalosang litlhoko, mekhoa ea teko, melao ea tlhahlobo, ho tšoaea, ho paka, ho tsamaisa le ho boloka lifilimi tsa ethylene-vinyl acetate copolymer (EVA) bakeng sa photovoltaic module encapsulation. Tse latelang ke tse ling tsa litlhoko tsa mantlha tse boletsoeng maemong a tloaelehileng:
Sebaka sa ts'ebeliso: Tekanyetso ena e sebetsa ho lifilimi tsa EVA bakeng sa encapsulation ea module ea photovoltaic, 'me e totobatsa lifilimi tsa EVA tse pepeneneng le lifilimi tse tšoeu tsa EVA.
Melao le litlhaloso: E kentse lipehelo le litlhaloso tsa lifilimi tsa EVA tse pepeneneng, lifilimi tse tšoeu tsa EVA, le bokahare ba bokaholimo, 'me ea hlakola melaoana le litlhaloso tsa lifilimi tsa EVA, degree ea crosslinking, le sekhahla sa ho honyela.
Litlhoko tsa lintlha: E fetotse litlhoko tsa lintlha, e arotsoe ka litlhaloso tsa EVA tse pepeneneng le litlhaloso tse tšoeu tsa EVA, 'me e kenyellelitse ho kheloha ha bokaholimo.
Litlhoko tsa ponahalo: E kenyellelitse litlhoko tsa "ha ho na li-creases le matheba"
Litlhoko tsa ts'ebetso ea 'mele: E kentse litlhoko tsa ts'ebetso ea 'mele ea EVA e pepeneneng, e fetotse phetisetso, matla a peel, ho hanyetsa molumo, ho hanyetsa botsofali ba UV, mocheso o phahameng le ts'ebetso ea botsofali bo phahameng, le ho fetola matla a ho senyeha ha motlakase ho matla a motlakase, ho eketsa matla a tsitsitseng, ho lelefatsa. nakong ea khefu, index ea ho hanyetsa ho latela, ts'ebetso ea ho tsofala ha mocheso o omileng (ntho ea boikhethelo), mocheso o phahameng oa UV le ts'ebetso ea botsofali e phahameng ea mongobo (ntho ea boikhethelo), ts'ebetso ea botsofali ea PCT (ntho ea boikhethelo)
Maemo a teko: Fetola "litlhokahalo tsa lisampole" ho "Likarolo tsa liteko", 'me u lokise litlhoko tse amehang
Mekhoa ea liteko: e fetotse mokhoa oa tlhahlobo ea botenya, e kenyellelitse mokhoa oa tlhahlobo ea ho kheloha ha sekhahla sa bokaholimo; fetola mokhoa oa ho hlahloba ponahalo; e ekelitse mokhoa oa teko oa ho kheloha ha sekhahla sa bokaholimo; e hlakotse mokhoa oa tlhahlobo ea litaba tsa vinyl acetate (VA); e fetotse mokhoa oa tlhahlobo ea phetiso; e ekelitse mokhoa oa tlhahlobo ea reflectivity; e fetotse mokhoa oa tlhahlobo ea degree ea crosslinking; e ekelitse matla a tsitsipano le bolelele ka mekhoa ea liteko tsa khefu; e fetotse mokhoa oa teko ea matla a peel; e fetotse mokhoa oa tlhahlobo ea shrinkage; e fetotse mokhoa oa tlhahlobo ea matla a motlakase; e ekelitse mokhoa oa tlhahlobo oa index ea ho hanyetsa; e fetotse mokhoa oa teko ea ho hanyetsa botsofali oa UV; e fetotse mokhoa oa tlhahlobo ea ts'ebetso ea mocheso o phahameng le mongobo o phahameng; e ekelitse ts'ebetso ea ho tsofala ha mocheso o omileng, mocheso o phahameng oa UV le ts'ebetso ea botsofali e phahameng ea mongobo, mekhoa ea tlhahlobo ea ts'ebetso ea botsofali ea PCT
Melao ea tlhahlobo: e ekelitse "lintlha le liphapang" linthong tsa tlhahlobo ea fektheri; e fetotse tlhahlobo ea mofuta
Ho paka, ho tsamaisa le ho boloka: ho fetola bophelo ba sethala sa sehlahisoa ka mor'a hore lebokose la liphutheloana le buloe.
Melao ena e netefatsa ts'ebetso le boleng ba filimi ea EVA ka photovoltaic module encapsulation ho finyella litlhoko tsa indasteri ea photovoltaic.
Ke lintho life tsa liteko tse kenyellelitsoeng ho standard ea ASTM D1043?
Tekanyetso ea ASTM D1043 haholo-holo e kenyelletsa tlhahlobo ea torsion ea lisebelisoa tsa polasetiki tlas'a liphetoho tsa mocheso ho fumana litšobotsi tsa bona tse thata. Tse latelang ke tse ling tsa lintho tsa tlhahlobo tse kenyellelitsoeng ho standard ea ASTM D1043:
Torsional stiffness: Ho leka ho tiea ha torsional ea thepa ea polasetiki ka mocheso o fapaneng, e leng parameter ea bohlokoa ea ho lekanya bokhoni ba thepa ea ho hanela deformation ea torsional.
Ho itšetleha ka mocheso: Ho lekola hore na ho tiea ha torsional ea thepa ea polasetiki ho fetoha joang ka mocheso, e leng habohlokoa ho utloisisa ts'ebetso ea thepa tlas'a maemo a fapaneng a tikoloho.
Torsional creep: Ho lekanya deformation ea torsional ea thepa ea polasetiki ka nako tlas'a torque e sa feleng ho lekola botsitso ba nako e telele ba thepa.
Phomolo ea torsional: Ho lekola torque ea lisebelisoa tsa polasetiki tlasa deformation e sa feleng ea torsional ka nako ho utloisisa litšobotsi tsa khatello ea maikutlo tsa thepa.
Tekanyetso ea ASTM D1043 e fana ka mokhoa oa ho lekola matšoao ana a ts'ebetso ea thepa ea polasetiki ka tlhahlobo ea torsion, e leng bohlokoa bo boholo mabapi le khetho ea thepa, moralo oa sehlahisoa le taolo ea boleng. Ka lintho tsena tsa liteko, ho ka netefatsoa ho ts'epahala le ho tšoarella ha lisebelisoa tsa polasetiki lits'ebetsong tse fapaneng.
