Thylene-vinyl acetate copolymer Amfani da Synthesis
| Bayani | Ethylene-vinyl acetate copolymer yana da tasiri mai kyau da juriya da juriya na damuwa, taushi, babban elasticity, juriya mai juriya da kwanciyar hankali na sinadarai, kayan lantarki mai kyau, mai kyau biocompatibility, da ƙananan yawa, kuma yana dacewa da masu cikawa, ma'aikatan wutan wuta suna da kyakkyawar dacewa.It. ana amfani da shi ne don samfuran filastik. |
| Kaddarorin jiki | Ethylene vinyl acetate yana samuwa azaman farin waxy daskararru a cikin pellet ko foda.Fina-finan ba su da haske. |
| Amfani | Bututu mai sassauƙa, mai da hankali mai launi, gaskets da sassa da aka ƙera don motoci, ruwan tabarau na filastik da famfo. |
| Ma'anarsa | Wani elastomer da aka yi amfani da shi don inganta abubuwan mannewa na zafi-narke da manne-matsi-matsi, da kuma don canza sutura da thermoplastics. |
| Hanyoyin samarwa | Ana iya samun nau'ikan nau'ikan nau'ikan nau'ikan kwayoyin halitta na bazuwar ethylene vinyl acetate copolymers ta hanyar polymerization mai matsa lamba mai ƙarfi, ci gaba da polymerization, ko polymerization bayani. |
| Babban Bayani | Polyethylene -co-vinyl acetate) (PEVA) abu ne mai hana wuta tare da kyawawan kayan inji da na zahiri.An fi amfani da shi azaman kayan rufe fuska a masana'antar waya da na USB. |
| Aikace-aikacen Magunguna | Ana amfani da Ethylene vinyl acetate copolymers azaman membranes da goyan baya a cikin tsarin isar da magungunan transdermal laminated.Hakanan ana iya haɗa su azaman abubuwan haɗin gwiwa a cikin goyan baya a cikin tsarin transdermal.Ethylene vinyl acetate copolymers an nuna su zama matrix mai tasiri da membrane don isar da sarrafawa na atenolol triprolidine, da furosemide.Za'a iya ƙara haɓaka tsarin don sakin atenolol mai sarrafawa ta amfani da ethylene vinyl acetate copolymers da plasticizers. |
| Tsaro | Ethylene vinyl acetate ana amfani dashi da yawa a cikin aikace-aikacen harhada magunguna azaman membrane ko tallafin fim.Gabaɗaya ana ɗaukarsa azaman abin ƙarawa mara guba kuma mara kuzari. |
| ajiya | Ethylene vinyl acetate copolymers suna da ƙarfi a ƙarƙashin yanayin al'ada kuma yakamata a adana su a wuri mai sanyi, bushe.Fina-finan na ethylene vinyl acetate copolymers yakamata a adana su a 0-30 ° C kuma ƙasa da 75% zafi dangi. |
| Rashin daidaituwa | Ethylene vinyl acetate bai dace ba tare da ma'aikatan oxidizing masu karfi da tushe. |
| Matsayin Gudanarwa | Haɗe a cikin Database Ingredients Intrauterine (suppository intrauterine, ophthalmic shirye-shirye, periodontal film, transdermal film).Haɗe a cikin magungunan da ba na mahaifa ba masu lasisi a Burtaniya. |
