CAS NO: 25067-34-9 Poly (vinyl Alcohol-co-ethylene)

Thaum siv rau ethanol lub cev qhuav dej, kev xaiv ntawm Poly (vinyl cawv-co- ethylene) pervaporation membrane tuaj yeem ncav cuag 1000-10,000, nrog rau kev sib cais siab. Piv nrog rau cov tshuaj distillation ib txwm, kev siv hluav taws xob raug txo los ntawm 30-70%, thiab tsis tas yuav tsum muaj cov co- boiling agent. Cov txheej txheem yooj yim dua thiab tus nqi qis dua.

Poly (vinyl cawv-co-ethylene) feem ntau yog hloov kho los ntawm kev sib xyaw lossis grafting los txhim kho nws cov khoom ua haujlwm thiab kev tiv thaiv dej noo. Kev sib xyaw ua ke tuaj yeem txo qis qhov cuam tshuam me ntsis, thaum nruab nrab grafting feem ntau tuaj yeem tswj tau lossis txawm tias txhim kho nws qhov kev ua tau zoo ntawm cov pa oxygen barrier.

1. Exceptional gas barrier zog, zoo daws teeb meem ntawm cov zaub mov oxidation thiab spoilage.
2. Tsis muaj ntxhiab tsw, khoom noj khoom haus - qib kev nyab xeeb, ua tau raws li qhov yuav tsum tau muaj rau kev sib cuag zaub mov.
3. Kev khaws cia zoo heev ntawm qhov tsw thiab ua haujlwm rau ntau yam xov xwm, haum rau ntau hom zaub mov.
4. Zoo molding thiab cov khoom sib xyaw, ua tau raws li kev xav tau ntau yam ntawm cov txheej txheem ntim khoom.
5. Tsim nyog qhov kub thiab txias tsis kam, haum rau kev tshaj tawm - kev ntim khoom noj thiab kev siv cov xwm txheej.

1.Hloov siab heev tshuaj thiab electrochemical stability
2. Zoo heev thermal stability thiab tsis kam rau thermal contraction
3. Tsim nyog microporous qauv thiab ionic conductivity
4. Zoo heev electrolyte wettability thiab kua tuav khoom
5. Sib npaug ntawm cov neeg kho tshuab lub zog thiab yooj
6. Tsawg hygroscopicity thiab oxygen- thaiv cov khoom

Raws li kev cuam tshuam kev kho mob ua kua embolic tus neeg sawv cev, lub hauv paus tseem ceeb nyob rau hauv kev ua tiav kev kho mob embolization los ntawm kev txhaj tshuaj, hauv -situ theem transformation rau solidification, thiab meej sealing ntawm lub hom phiaj cov hlab ntsha. Nws cov txheej txheem ntawm kev ua yog tag nrho raws li cov khoom ntawm tus kheej cov yam ntxwv ntawm cov theem hloov pauv, rheological zog, biocompatibility, lub cev - cov cuab yeej cuab tam, thiab kev tswj kev degradation, thiab txhua yam ntawm cov khoom no tau sib xws nrog cov kev xav tau ntawm kev kho mob embolization. Qhov no yog qhov laj thawj tseem ceeb vim li cas nws tuaj yeem dhau los ua siab - cov khoom siv vascular embolic kawg. Cov txheej txheem tshwj xeeb ntawm kev nqis tes ua thiab kev sib raug zoo ntawm kev ua haujlwm yog raws li hauv qab no:
