Isicelo se-EVA foam material

I-EVA iyi-polymer yesine ngobukhulu yochungechunge lwe-ethylene ngemuva kwe-HDPE, i-LDPE ne-LLDPE.Uma kuqhathaniswa nezinto zendabuko, izindleko zayo ziphansi kakhulu.Abantu abaningi bacabanga ukuthi okokusebenza kwegwebu le-EVA kuyinhlanganisela ephelele yegobolondo eliqinile negobolondo elithambile, eligcina izinzuzo zegwebu elithambile neliqinile ngenkathi ishiya okubi.Futhi, ukuguquguquka okungokwemvelo ekwakhiweni kwezinto ezibonakalayo namandla okukhiqiza nakho kuyisici esikhulu kwezinye izinkampani ezihamba phambili emhlabeni nemikhiqizo ephendukela kugwebu lwe-EVA lapho kudingeka izinto zokwakha ezisezingeni eliphezulu, ezingabizi kakhulu.

Isithombe esivela ku: Foamty

Ngaphezu kokuguquguquka, impahla ye-EVA yegwebu inakekela impilo yethu yansuku zonke nemisebenzi yebhizinisi, futhi iveze umusa wabasebenzisi bokugcina.Izicathulo, imithi, amaphaneli e-photovoltaic, imikhiqizo yezemidlalo nezokungcebeleka, amathoyizi, amacansi aphansi/i-yoga, okupakishwayo, okokusebenza kwezokwelapha, izinto zokuzivikela, imikhiqizo yezemidlalo yamanzi idingeka kakhulu ngemikhiqizo yepulasitiki ehlala isikhathi eside, futhi ingxenye yemakethe yezinto ze-EVA foam iyaqhubeka nokungena. ukukhula okusha kwe.

EVA izakhiwo zomzimba kanye mechanical

Izici zama-copolymers e-EVA zinqunywa ngokuyinhloko okuqukethwe kwe-vinyl acetate kanye nezinga lokumanzi.Ukwanda kokuqukethwe kwe-VA kukhulisa ukuminyana, ukucaca kanye nokuguquguquka kwezinto ngenkathi kunciphisa iphuzu lokuncibilika nobulukhuni.I-Ethylene-vinyl acetate copolymer (EVA) iyimpahla enwebeka kakhulu engakwazi ukucwiliswa ukuze yakhe igwebu elifana nerabha, kodwa ngamandla amakhulu.Iguquguquka ngokuphindwe kathathu kune-low density polyethylene (LDPE), inobude obuqinile obungu-750%, futhi inezinga lokushisa eliphakeme lokuncibilika elingu-96°C.

Ngokuya ngezithako zenqubo yokukhiqiza, amazinga ahlukene wobulukhuni be-EVA angafinyelelwa.Kubalulekile ukugcina izinga elilinganiselwe lobulukhuni ngoba i-EVA ayibuyiseli isimo sayo ngemva kokucindezelwa okuqhubekayo.Uma kuqhathaniswa ne-EVA eqinile, i-EVA ethambile imelana kancane nemihuzuko futhi inobude bokuphila obufushane iyodwa, kodwa inethezekile.

Igwebu le-Anti-static EVA aligcini nje ngokuba nomphumela omuhle we-anti-static buffering, kodwa futhi linokumelana nokucindezela okuphelele.
Ngokusekelwe kugwebu le-ESD EVA, kunezinhlobo eziningi: amabhokisi egwebu aqoshwe, okufakwayo kwegwebu, amalayini ebhokisi e-PP, okufakwayo okufakwayo, njll.,

Omakhalekhukhwini, amatheminali e-3G, amakhompiyutha, izingxenye ze-optoelectronic, amabhokisi okwenza inzuzo.Faka izingxenye zekhompiyutha yamanothi endaweni yekhadi eyenziwe ngokotini wegwebu, bese uhlanganisa umugqa ndawonye ukuze uthuthukise ukusebenza kahle komsebenzi.Isetshenziswa kuma-workshops we-motherboard kanye ne-PCB ukugwema ukusika izingxenye ze-elekthronikhi nezandla ngesikhathi sokusetshenziswa;Isibonisi sokuvikela se-LCD namasekhethi okulawula emigqa yokukhiqiza iphaneli ye-LCD.
