I-Thylene-vinyl acetate copolymer Usetyenziso kunye ne-Synthesis
| Inkcazo | I-Ethylene-vinyl acetate copolymer inokumelana nempembelelo elungileyo kunye nokumelana noxinzelelo lokuqhekeka, ukuthamba, ukuqina okuphezulu, ukuchasana nokubhoboza kunye nokuzinza kweekhemikhali, iipropathi ezilungileyo zombane, ukuhambelana kakuhle kwe-biocompatibility, kunye noxinzelelo oluphantsi, kwaye iyahambelana nezigcwalisi, iiarhente zokubuyiswa komlilo zinokuhambelana kakuhle. ikakhulu isetyenziselwa iimveliso zeplastiki. |
| Iimpawu ezibonakalayo | I-ethylene vinyl acetate ifumaneka njengeziqina ezimhlophe ze-waxy kwi-pellet okanye kwifom yomgubo.Iifilimu ziguquguqukayo. |
| Usebenzisa | Iityhubhu eziguquguqukayo, izigxina zombala, iigaskets kunye neendawo ezibunjiweyo zeemoto, iilensi zeplastiki kunye neempompo. |
| Ingcaciso | I-elastomer esetyenziselwa ukuphucula iimpawu zokubambelela kwi-hot-melt kunye ne-adhesive-sensitive adhesives, kunye nokuguqulwa kweengubo kunye ne-thermoplastics. |
| Iindlela zeMveliso | Ubunzima beemolekyuli ezahlukeneyo ze-ethylene vinyl acetate copolymers zinokufumaneka ngoxinzelelo oluphezulu lwepolymerization, isambuku esiqhubekayo sepolymerization, okanye isisombululo sepolymerization. |
| Inkcazo ngokubanzi | Poly (ethylene-co-vinyl acetate) (i-PEVA) yinto enqanda ilangatye kunye neempawu ezintle zoomatshini kunye nezomzimba.Isetyenziswa kakhulu njengento yokugquma kushishino lweengcingo kunye nentambo. |
| Ukusetyenziswa kwezamayeza | I-ethylene vinyl acetate copolymers isetyenziswa njengeembumba kunye neenkxaso kwiinkqubo zokuhanjiswa kweziyobisi ezigqithisiweyo.Ziyakwazi ukufakwa njengamacandelo kwii-backings kwiinkqubo ze-transdermal.I-ethylene vinyl acetate copolymers ibonakaliswe njenge-matrix esebenzayo kunye ne-membrane yokuhanjiswa okulawulwayo kwe-atenolol triprolidine, kunye ne-furosemide.Inkqubo yokukhutshwa okulawulwayo kwe-atenolol ingaphuhliswa ngakumbi ngokusebenzisa i-ethylene vinyl acetate copolymers kunye neplastiki. |
| Ukhuseleko | I-ethylene vinyl acetate isetyenziswa kakhulu kwizicelo zoxubo lwamayeza njengenwebu okanye ifilimu exhasayo.Ngokubanzi ithathwa njengento engeyotyhefu nengakhuphiyo. |
| yokugcina | I-ethylene vinyl acetate copolymers izinzile phantsi kweemeko eziqhelekileyo kwaye kufuneka igcinwe kwindawo epholileyo, eyomileyo.Iifilimu ze-ethylene vinyl acetate copolymers kufuneka zigcinwe kwi-0-30 ° C kwaye ngaphantsi kwe-75% yomswakama ohambelanayo. |
| Ukungahambelani | I-ethylene vinyl acetate ayihambelani ne-oxidizing agents kunye neziseko eziqinileyo. |
| Ubume boLawulo | Ibandakanyiwe kwi-FDA ye-Inactive Ingredients Database (i-intrauterine suppository; amalungiselelo e-ophthalmic; ifilimu ye-periodontal; ifilimu ye-transdermal).Ibandakanywe kumayeza angengobazali anikwe ilayisenisi e-UK. |
