Isicelo

I-Ethylene-vinyl acetate copolymer CAS 24937-78-8 (EVA) ineentlobo ngeentlobo zezicelo, ezi zilandelayo zezona ndawo ziphambili zokusetyenziswa kwayo:

Intsimi yefilimu encinci

Ifilimu yezolimo: I-EVA inomoya olungileyo wokudlulisa ukukhanya, igcina ubushushu kwaye iyamelana nemozulu, kwaye isetyenziswa rhoqo ekuveliseni ifilimu yezolimo. Ingagcina ubushushu kunye nomswakama kwi-greenhouse ngempumelelo, ikhuthaze ukukhula kwezityalo, kwaye yandise ubomi benkonzo yefilimu.

Ifilimu yokupakishwa: Ifilimu ye-EVA inokuguquguquka okuhle, ukucaca kunye nokumelana nokubhoboza, ifanelekile ukupakishwa kweemveliso ezahlukeneyo, ezinje ngokutya, izinto ezifunekayo imihla ngemihla, njl. Ingabonelela ngokusebenza kakuhle kokhuseleko ngelixa ibonisa inkangeleko yemveliso.

Intsimi yezinto zezihlangu

Isole: I-EVA ineempawu zokuthamba, ukuthamba okuhle, ubunzima obulula, ukumelana nokuguguleka, njl.njl., yeyona nto ifanelekileyo yokwenza isole. Isole eyenziwe nge-EVA ikhululekile ukunxitywa, inokusebenza kakuhle kokufunxa ukuthuthumela, kwaye inokunciphisa ukudinwa kweenyawo.

Ngaphezulu: I-EVA ingasetyenziselwa ukwenza izinto eziphezulu, inika ukuchukumisa okuthambileyo kunye nokuphefumla kakuhle, yenza izihlangu zibe mnandi kwaye zibukeke ngakumbi.

Intsimi yokuncamathelisa eshushu enyibilikayo

I-EVA hot melt adhesive: ineenzuzo ze-viscosity enamandla, ukucocwa ngokukhawuleza, ukumelana nobushushu obuphantsi, njl.njl., isetyenziswa kakhulu ekupakisheni, ekubopheni, ekuveliseni ifenitshala nakwamanye amashishini. Ingasetyenziselwa ukubopha iphepha, umthi, iplastiki nezinye izinto, kulula ukuyisebenzisa, inokuphucula ukusebenza kakuhle kwemveliso.

Intsimi yentambo kunye nentambo

Umaleko wokufaka ubushushu: I-EVA isebenza kakuhle ekufakeni ubushushu, ukumelana namanzi kunye nokumelana nokugqwala ngamakhemikhali, ingasetyenziswa njengesixhobo sokufaka ubushushu kwiingcingo kunye neentambo, inokukhusela ngokufanelekileyo iingcingo kunye neentambo kwimpembelelo yendalo yangaphandle, ukuqinisekisa ukhuseleko kunye nokuthembeka kokudluliselwa kwamandla.

Isingxobo: I-EVA ingasetyenziselwa ukwenza isingxobo sentambo kunye neentambo, inika ukhuseleko loomatshini kunye nokusebenza okulwa nokwaluphala, yandisa ubomi benkonzo yentambo kunye neentambo.

Ezinye iintsimi

Izinto Zokudlala: I-EVA ithambile, ayinatyhefu, ayinavumba kwaye inezinye iimpawu, idla ngokusetyenziswa ukwenza izinto zokudlala, ezifana neebhola zokudlala zabantwana, iiphazili, njl.njl., ukuqinisekisa ukhuseleko kunye nentuthuzelo yokusetyenziswa ngabantwana.

Izinto zemidlalo: Ikwasetyenziswa kakhulu kwizinto zemidlalo, ezifana ne-MATS yezemidlalo, i-yoga MATS, njl.njl., apho ukuthamba kwayo nokuthamba kwayo kunokubonelela ngenkxaso elungileyo kunye nefuthe lokuthomalalisa.

Iimveliso zeFoam: Ifoam ye-EVA inobunzima obuphantsi, ithambile, igcina ubushushu, igcina isandi kunye nezinye iimpawu, ingasetyenziselwa ukwenza iintlobo ngeentlobo zeemveliso zefoam.
