Isicelo

I-Ethylene-vinyl acetate copolymer CAS 24937-78-8 (EVA) inoluhlu olubanzi lwezicelo, ezi zilandelayo ziindawo zayo eziphambili zesicelo:

Indawo yefilimu ebhityileyo

Ifilimu yezoLimo: I-EVA inokuhanjiswa kokukhanya okulungileyo, ukugcinwa kobushushu kunye nokumelana nemozulu, kwaye ihlala isetyenziselwa ukuveliswa kwefilimu yezolimo. Inokugcina ngokufanelekileyo ubushushu kunye nomswakama kwi-greenhouse, ukukhuthaza ukukhula kwezityalo, kunye nokwandisa ubomi benkonzo yefilimu.

Ifilimu yokupakisha: Ifilimu ye-EVA inokuguquguquka okulungileyo, ukungafihli kunye nokuchasana kwe-puncture, ilungele ukupakishwa kweemveliso ezahlukeneyo, ezifana nokutya, iimfuno zemihla ngemihla, njl. Inokubonelela ngokusebenza kakuhle kokukhusela ngelixa ibonisa ukubonakala kwemveliso.

Intsimi yezinto zesihlangu

I-Sole: I-EVA ineempawu zokuthamba, i-elasticity elungileyo, ubunzima obulula, ukumelana nokunxiba, njl., Yeyona nto ifanelekileyo yokwenza yodwa. I-Sole eyenziwe nge-EVA ikhululekile ukunxiba, inokusebenza kakuhle kokufunxa ukothuka, kwaye inokunciphisa ukudinwa kweenyawo.

Upper: I-EVA ingasetyenziselwa ukwenza izinto eziphezulu, ukubonelela ngokuchukumisa okuthambileyo kunye nokuphefumla okulungileyo, ukwenza izihlangu zibe zikhululekile kwaye zihle.

Intsimi yokuncamathelisa inyibilika eshushu

I-Adhesive eshushu yokunyibilika kwe-EVA: ineenzuzo ze-viscosity eyomeleleyo, ukunyanga ngokukhawuleza, ukuxhathisa ubushushu obuphantsi, njl., isetyenziswa ngokubanzi ekupakisheni, ukubopha, ukwenza ifenitshala kunye namanye amashishini. Ingasetyenziselwa ukubopha iphepha, iinkuni, iplastiki kunye nezinye izinto, kulula ukuyisebenzisa, inokuphucula ukusebenza kakuhle kwemveliso.

Ucingo kunye nendawo yentambo

I-Insulation layer: I-EVA inokusebenza kakuhle kwe-insulation, ukumelana kwamanzi kunye nokuxhathisa ukubola kweekhemikhali, ingasetyenziselwa njengento yokukhusela i-insulating ye-wire kunye nekhebula, inokukhusela ngokufanelekileyo ucingo kunye nentambo kwimpembelelo yendalo yangaphandle, ukuqinisekisa ukhuseleko kunye nokuthembeka kokuhanjiswa kwamandla.

I-Sheath: I-EVA ingasetyenziselwa ukwenza i-sheath yocingo kunye nekhebula, ukubonelela ngokhuseleko lomatshini kunye nokusebenza okuchasene nokuguga, ukwandisa ubomi benkonzo yocingo kunye nentambo.

Amanye amabala

Izinto zokudlala: I-EVA ithambile, ayinatyhefu, ayinavumba kunye nezinye iimpawu, ehlala isetyenziselwa ukwenza iithoyi, ezinjengeebhola zokudlala zabantwana, iipuzzle, njl.njl., ukuqinisekisa ukhuseleko kunye nentuthuzelo yokusetyenziswa kwabantwana.

Impahla yezemidlalo: Ikwasetyenziswa ngokubanzi kwimpahla yezemidlalo, njenge-MATS yezemidlalo, i-yoga MATS, njl., Ukuthamba kwayo kunye no-elasticity kunokubonelela ngenkxaso efanelekileyo kunye nomphumo wokunciphisa.

Iimveliso ze-Foam: I-EVA i-foam inobunzima obulula, ithambileyo, igcina ubushushu, i-insulation yesandi kunye nezinye iipropathi, ingasetyenziselwa ukwenza iimveliso ezahlukeneyo ze-foam.
