Isticmaalka iyo Isku-dhafka taylin-vinyl acetate copolymer
| Sharaxaada | Ethylene-vinyl acetate copolymer waxay leedahay saameyn wanaagsan oo iska caabin ah iyo iska caabin dildilaac ah, jilicsanaan, dabacsanaan sare, caabbinta daloolinta iyo xasiloonida kiimikada, guryaha korantada ee wanaagsan, biocompatibility wanaagsan, iyo cufnaanta hoose, waxayna ku habboon tahay buuxinta, wakiilada ololka ayaa leh iswaafajin wanaagsan.It. waxaa inta badan loo isticmaalaa alaabada balaastikada ah. |
| Tilmaamaha jirka | Ethylene vinyl acetate ayaa loo heli karaa sidii adkaha waxy cad oo pellet ama qaab budo ah.Aflaantu waa kuwo hufan. |
| Adeegsada | Tuubooyinka dabacsan, midabka midabada leh, gaasaska iyo qaybaha qaabaysan ee baabuurta, muraayadaha caaga ah iyo matoorada. |
| Qeexid | elastomer loo isticmaalo in lagu wanaajiyo sifooyinka xabagta ee kululaynta dhalaalaysa iyo xabagta xasaasiga ah, iyo sidoo kale dahaarka beddelka iyo heerkulbeegyada. |
| Hababka wax soo saarka | Miisaannada unugyada kala duwan ee ethylene vinyl acetate copolymers random waxaa lagu heli karaa polymerization xagjirka ah ee cadaadiska sarreeya, polymerization-ka joogtada ah, ama polymerization xalka. |
| Sharaxaada Guud | Poly (etylen-co-vinyl acetate) (PEVA) waa walxo ololka celisa oo leh qalab farsamo iyo jireed oo wanaagsan.Waxaa inta badan loo isticmaalaa sidii shay dahaarka ah ee siliga iyo warshadaha fiilooyinka. |
| Codsiyada Daawooyinka | Ethylene vinyl acetate copolymers waxaa loo isticmaalaa sidii xuubka iyo dhabarka ee hababka gudbinta daawada transdermal ee la dahaadhay.Waxa kale oo lagu dari karaa sida qaybo ka mid ah taageerada hababka transdermal.Ethylene vinyl acetate copolymers ayaa lagu muujiyay inay yihiin matrix wax ku ool ah iyo xuub loogu talagalay gaarsiinta atenolol triprolidine, iyo furosemide.Nidaamka lagu xakameynayo sii-deynta atenolol waa la sii horumarin karaa iyadoo la adeegsanayo ethylene vinyl acetate copolymers iyo balaastikada. |
| Badbaadada | Ethylene vinyl acetate waxaa inta badan loo adeegsadaa codsiyada dawooyinka ee jirka la mariyo sida xuubka ama filimka.Guud ahaan waxa loo tixgaliyaa sidii wax aan sun ahayn oo aan dhib lahayn. |
| kaydinta | Ethylene vinyl acetate copolymers waxay ku xasilloon yihiin xaaladaha caadiga ah waana in lagu kaydiyaa meel qabow oo qalalan.Filimada ethylene vinyl acetate copolymers waa in lagu kaydiyaa 0-30°C iyo in ka yar 75% qoyaan qaraabo ah. |
| Isqabsi la'aanta | Ethylene vinyl acetate waa mid aan la jaan qaadi karin wakiilada iyo saldhigyada oksaydhiyeyaasha xooggan. |
| Xaalada Sharci | Waxaa ku jira Database-ka Walxaha Aan Dhaqdhaqaaqa lahayn ee FDA (suppository intrauterine; diyaarinta indhaha, filimka periodontal, filim transdermal).Waxaa ku jira dawooyinka aan waalidnimada lahayn ee shatiyeysan UK. |
