Isicelo

I-Ethylene-vinyl acetate copolymer CAS 24937-78-8 (EVA) inezinhlobo eziningi zezicelo, okulandelayo yizindawo zayo eziyinhloko zokusetshenziswa:

Insimu yefilimu encane

Ifilimu yezolimo: I-EVA inokudlulisa ukukhanya okuhle, ukulondolozwa kokushisa kanye nokumelana nesimo sezulu, futhi ivame ukusetshenziswa ekukhiqizeni ifilimu yezolimo. Ingagcina kahle izinga lokushisa kanye nomswakama endlini eluhlaza okotshani, ikhuthaze ukukhula kwezitshalo, futhi yandise impilo yefilimu.

Ifilimu yokupakishwa: Ifilimu ye-EVA inokuguquguquka okuhle, ukucaca kanye nokumelana nokubhoboza, ifanelekela ukupakishwa kwemikhiqizo ehlukahlukene, njengokudla, izidingo zansuku zonke, njll. Ingahlinzeka ngokusebenza okuhle kokuvikela ngenkathi ikhombisa ukubukeka komkhiqizo.

Insimu yezinto zezicathulo

I-Sole: I-EVA inezici zokuthamba, ukunwebeka okuhle, isisindo esincane, ukumelana nokuguguleka, njll., iyimpahla efanelekile yokwenza i-sole. I-sole eyenziwe nge-EVA ikhululekile ukugqokwa, inokusebenza okuhle kokumunca ukushaqeka, futhi inganciphisa ukukhathala kwezinyawo.

Ngaphezulu: I-EVA ingasetshenziswa futhi ukwenza izinto zangaphezulu, inikeze ukuthinta okuthambile kanye nokuphefumula okuhle, okwenza izicathulo zibe mnandi futhi zibe zinhle.

Insimu yokunamathela encibilikayo eshisayo

I-EVA hot melt adhesive: inezinzuzo ze-viscosity eqinile, ukuphola okusheshayo, ukumelana nokushisa okuphansi, njll., esetshenziswa kabanzi ekupakisheni, ekubopheni, ekukhiqizeni ifenisha nakwezinye izimboni. Ingasetshenziswa ukubopha iphepha, ukhuni, ipulasitiki nezinye izinto, kulula ukuyisebenzisa, ingathuthukisa ukusebenza kahle kokukhiqiza.

Insimu yezintambo nekhebula

Isendlalelo sokuvikela: I-EVA isebenza kahle ekuvikeleni, ukumelana namanzi kanye nokumelana nokugqwala kwamakhemikhali, ingasetshenziswa njengesendlalelo sokuvikela ucingo kanye nekhebula, ingavikela ngempumelelo ucingo kanye nekhebula ethonyeni lemvelo yangaphandle, ukuqinisekisa ukuphepha nokuthembeka kokudluliselwa kwamandla.

Isivikelo: I-EVA ingasetshenziswa futhi ukwenza isivikelo sentambo nekhebula, ihlinzeka ngokuvikelwa komshini kanye nokusebenza kokulwa nokuguga, yandisa impilo yenkonzo yentambo nekhebula.

Ezinye izinkambu

Amathoyizi: I-EVA ithambile, ayinabo ubuthi, ayinaphunga nezinye izici, ivame ukusetshenziselwa ukwenza amathoyizi, njengebhola lamathoyizi ezingane, amaphazili, njll., ukuqinisekisa ukuphepha nenduduzo yokusetshenziswa kwezingane.

Izimpahla zemidlalo: Isetshenziswa kabanzi nasezimpahleni zemidlalo, njenge-sports MATS, i-yoga MATS, njll., okuthambile kwayo nokunwebeka kwayo okunganikeza ukwesekwa okuhle kanye nomphumela wokuthopha.

Imikhiqizo ye-Foam: I-foam ye-EVA inesisindo esincane, ithambile, igcina ukushisa, ivikela umsindo nezinye izakhiwo, ingasetshenziswa ukwenza imikhiqizo eyahlukahlukene ye-foam.
