Dab tsi yog PTFE membrane khoom

PTFE membrane khoom yog ua los ntawm superfine iav fiber ntau coated nrog PTFE cob.

PTFE yog cov khoom siv tshuaj polymer uas muaj polytetrafluoroethylene. Teflon high-performance tshwj xeeb txheej yog fluoro txheej nrog polytetrafluoroethylene li matrix resin. Polytetrafluoroethylene yog tsim los ntawm dawb radical polymerization ntawm tetrafluoroethylene. Hauv kev lag luam, cov tshuaj tiv thaiv polymerization yog ua los ntawm kev nplawm nyob rau hauv lub xub ntiag ntawm ib tug loj npaum li cas ntawm cov dej kom disperse cov tshuaj tiv thaiv kub thiab pab tswj kub. Polymerization feem ntau yog ua los ntawm 40 txog 80 degree, 3 mus rau 26 kgf / cm2, Inorganic persulfate thiab organic peroxide tuaj yeem siv los ua cov pib, lossis redox pib siv tau.

Qhov hnyav ntawm PTFE membrane qauv tsuas yog ib feem me me ntawm cov khoom siv hauv tsev, thiab nws tuaj yeem ncab mus rau ntau yam dynamic arc duab. Los ntawm cov teeb pom kev zoo sib xws ntawm qhov chaw sab hauv thiab sab nraud, ib qho muag tawg tawg yog tsim. Ntxiv mus, txhua lub thav duab yuav raug welded los ua ib lub ru tsev sib xyaw, thiab lub zog ntawm cov vuam yuav ntau dua li ntawm cov ntaub nws tus kheej, thaum nws tseem tuav lub teeb kis tau zoo.

Cov ntaub iav fiber ntau yog ib hom rov qab cov ntaub dawb thiab cov khoom siv tseem ceeb rau tes nteg GRP. Nws lub zog yog feem ntau nyob rau hauv warp thiab weft cov lus qhia ntawm cov ntaub. Nws muaj qhov zoo ntawm cov rwb thaiv tsev zoo, muaj zog tiv thaiv tshav kub, zoo corrosion kuj thiab siab mechanical zog, tab sis nws qhov tsis zoo yog nkig thiab hnav tsis zoo. Cov iav fiber ntau feem ntau yog siv los ua kev txhawb zog, hluav taws xob rwb thaiv tsev thiab thermal rwb thaiv tsev cov ntaub ntawv hauv cov ntaub ntawv sib xyaw.

Alkali dawb iav fiber, tseem hu ua E-iav fiber ntau, hais txog iav fiber ntau nrog cov ntsiab lus tsis tshua muaj alkali hlau oxide. Cov iav tsis muaj alkali muaj R2O cov ntsiab lus tsawg dua 0.8 feem pua, uas yog cov khoom siv alumino borosilicate. Qhov nruab nrab alkali iav fiber ntau muaj R2O cov ntsiab lus ntawm 11.9 feem pua ​​- 12.4 feem pua, uas yog sodium calcium silicate tivthaiv. Vim nws cov ntsiab lus alkali siab, nws tsis tuaj yeem siv los ua cov khoom siv hluav taws xob. Lub siab alkali iav fiber ntau muaj qhov tsis zoo ntawm lub zog tsis muaj zog, tsis zoo dej tsis kam thiab alkali tsis kam, Qhov tsis zoo no tsis tuaj yeem kov yeej.
