Isingeniso Esinemininingwane

I-Ethylene-vinyl acetate copolymer, kuvame ukufushaniswa njenge-EVA, kuyiphoyisa elenziwa ngokuhlanganiswa kwe-ethylene ne-vinyl acetate monomers. Kuyinto impahla eguquguqukayo esetshenziswe kuzicelo ezahlukahlukene ngenxa yezakhiwo zayo ezifiselekayo.
I-Eva Copolymer inendawo ephansi yokuncibilika, ukuguquguquka okungcono kakhulu, kanye nokulinganisela okuhle kobunzima nokuqina. Kuyamelana namanzi, imisebe ye-UV, namakhemikhali, akwenza kufanelekile ukuthola izinhlelo zangaphandle. Futhi inama-adhesion amahle kuma-substrates amaningi, okwenza ilungele ukusetshenziswa njenge-binder noma inamathegi.
Okunye kokusetshenziswa okuyinhloko kwe-EVA ekukhiqizweni kwamagwebu. Kusetshenziswa kabanzi ukudala i-cushioning kanye ne-padding workes, njengasezicabheni zezicathulo, imishini yezemidlalo, nezinto zokupakisha. I-Eva Foams inikezela ngesiqu, ukumunca ukushaqeka, nenduduzo.
I-Eva Copolymer nayo isetshenziswa ekukhiqizeni amafilimu namashidi. Ukucacisa kwalo, ukuvumelana nezimo, kanye nokusebenza okushisa okuphansi kwenza kube lula ukuthola izinhlelo zokusebenza ezinjengezembozo zokugcina abamba ukushisa, ingilazi eyakhiwe phansi, kanye namaphaneli elanga.
Izici zokufakwa kukagesi nezeshisayo ze-EVA zenza zilusizo embonini ye-wire kanye ne-cable. I-EVA Coathings kanye nezinto zokwehlukanisa izinto ezisetshenziselwa ukuvikela nokufaka izintambo zikagesi nezintambo.Ewokhoshelwa ukusetshenziswa kwe-EVA kufaka phakathi izimoto, amadivaysi ezokwelapha, amathoyizi kanye nezinto zokupakisha.
Sekukonke, i-ethylene-vinyl acetate copolymer iyinto eguquguqukayo enezinto ezinhle kakhulu ezenza zilungele ukusetshenziswa kwezicelo ezahlukahlukene.

Isicelo

I-Ethylene-Vinyl Acetate Copolymer (EVA) inezicelo eziningi ezahlukahlukene kuyo yonke imboni ehlukahlukene ngenxa yenhlanganisela yayo eyingqayizivele yezakhiwo. Nazi ezinye izinhlelo ezijwayelekile ze-EVA:
Izicathulo:U-Eva usetshenziswa kabanzi ekukhiqizweni kwezicathulo, ikakhulukazi ama-midsoles nama-insoles. Inika i-cushioning, ukumuncwa ukushaqeka, kanye nokuvumelana nezimo, okwenza kube ukukhetha okuthandwayo kwezicathulo zezemidlalo, izimbadada, kanye nama-slipper.
Ukupakishwa:I-EVA isetshenziswa kwizicelo zokupakisha njengoba inikeza ukumelana okuhle kakhulu nokuvumelana nezimo. Isetshenziswa kakhulu njengokufaka okuphephile kokufakelwa, ama-foam Pooches, kanye nokufaka amabhokisi amabhokisi neziqukathi ukuvikela imikhiqizo ebuthakathaka noma ethambile ngesikhathi sokuhamba.
Izinamathiseli nama-sealants:U-Eva Copolymer usetshenziswa njengezinto eziyisisekelo ekukhiqizweni kwezikhangiso kanye nama-sealants. Inikeza ukunamathela okuhle kuma-substrates ahlukahlukene, njengamapulasitiki, izinsimbi nokhuni, okwenza kufanelekile ukuthola izinhlelo zokusebenza.
I-Wire ne-Cable Insulation:I-EVA isetshenziswa njengezinto zokufakelwa kwezintambo zikagesi nezintambo ngenxa yezakhiwo zayo ezinhle kakhulu zokufaka ugesi. Inika ukumelana nomswakama, amakhemikhali, kanye nokuguga, ukuqinisekisa ukuphepha nokwethenjwa kwezinhlelo zikagesi.
Ifilimu neshidi:U-Eva uvame ukusetshenziselwa ukukhiqiza amafilimu namashidi ngokuhlukahluka okuhlukahlukene. Lawa mafilimu athola izinhlelo zokusebenza kwezolimo, emboza abamba ukushisa, ukupakishwa kokudla, amaphaneli elanga, nengilazi eyakhiwe phansi.
Amadivaysi ezokwelapha:I-EVA isetshenziswa embonini yezempilo ukukhiqiza amadivaysi ezokwelapha, njengama-catheter, tubing kanye nemidwebo yokuhlinza. Inikeza i-BIOCOMTIL, ukuguquguquka, futhi ukucubungulwa okulula kuyadingeka kwizicelo zezokwelapha.
Amathoyizi nemikhiqizo yokuzijabulisa:I-EVA isetshenziswa kabanzi ekukhiqizweni kwamathoyizi nemikhiqizo yokuzijabulisa, kufaka phakathi iphazili ye-Foam, amadivaysi okuntanta, ama-yoga mat, nemishini yezemidlalo ye-foam. Inika i-cushioning, ukuphepha, nokuqina kwalezi zicelo.
Izimoto ezisebenzayo:Izinto zokwenziwa ze-Eva Foam ziqashwa ezicelo zezimoto zokufakelwa okuzwakalayo, ukudliwa kwe-vibration, kanye nokumelana nomthelela. Kuyasiza ukunciphisa umsindo, kuthuthukise induduzo, futhi kunikeze ukuvikela ngezimoto eziphakathi.
Lezi yizibonelo ezimbalwa nje zezicelo eziningi ze-EVA. Ukuguquguquka okuhlukahlukene, ukuvumelana nezimo, nokuqina kwenza kube yinto esetshenziswa kabanzi ezimbonini ezahlukahlukene.
