Optimize stretching thiab expansion txheej txheem: stretching thiab expansion yog cov kauj ruam tseem ceeb nyob rau hauv zus tau tej cov ePTFE daim nyias nyias, uas ncaj qha cuam tshuam rau lub porosity thiab pore loj ntawm daim nyias nyias. Los ntawm optimizing cov txheej txheem ncab thiab nthuav dav, qhov porosity thiab pore loj ntawm daim nyias nyias tuaj yeem ua kom zoo dua qub thiab cov dej tsis zoo tuaj yeem txhim kho. Piv txwv li, cov txheej txheem biaxial stretching tuaj yeem ua rau kev ua haujlwm ntawm daim nyias nyias nyias nyob rau hauv ob qho tib si cov lus qhia thiab txhim kho cov dej tsis zoo.
nruj me ntsis tswj lub sintering thiab txias tej yam kev mob: lub sintering thiab txias txheej txheem muaj ib tug tseem ceeb lub luag hauj lwm rau lub intermolecular bonding quab yuam thiab structural stability ntawm ePTFE membrane. Los ntawm kev tswj hwm cov sintering thiab txias txias, lub zog sib txuas tuaj yeem tsim los ntawm cov molecules ntawm daim nyias nyias, txhim kho cov qauv kev ruaj ntseg thiab tsis muaj dej tsis zoo ntawm daim nyias nyias. Piv txwv li, tsim nyog nce qhov kub ntawm sintering tuaj yeem ua rau lub zog sib txuas ntawm polytetrafluoroethylene molecules muaj zog thiab txhim kho cov dej tsis zoo ntawm daim nyias nyias.
3. Cov txheej txheem tom qab kho:
Ua kom sov qhov chaw kho mob: Thaum tshav kub kub tuaj yeem ua rau cov qauv ntawm ePTFE membrane ruaj khov, txo qhov deformation thiab shrinkage ntawm daim nyias nyias thaum siv, thiab yog li txhim kho cov dej tsis zoo. Piv txwv li, cua sov teeb lub membrane ntawm ib tug tej yam kub thiab lub sij hawm yuav ua rau lub pore loj thiab porosity ntawm daim nyias nyias ruaj khov thiab txhim kho cov nyhuv waterproof.
Kev kho deg: Kho qhov chaw ntawm ePTFE daim nyias nyias, xws li txheej txheej txheej tsis muaj dej, kev kho ntshav plasma, thiab lwm yam, tuaj yeem txhim kho qhov ntub dej ntawm daim nyias nyias thiab txhim kho nws cov dej tsis zoo. Piv txwv li, txheej txheej ntawm fluorocarbon waterproof txheej tuaj yeem ua rau saum npoo ntawm daim nyias nyias ntau hydrophobic thiab txhim kho cov dej tsis zoo; Kev kho cov ntshav plasma tuaj yeem qhia qee pawg polar nyob rau saum npoo ntawm daim nyias nyias los txhim kho qhov ntub dej ntawm daim nyias nyias thiab txhim kho nws cov dej tsis zoo.
4. Composite nrog lwm cov ntaub ntawv:
Compounding nrog waterproof fabrics: Compounding ePTFE membrane nrog waterproof fabrics tuaj yeem tsim cov khoom sib xyaw nrog cov dej tsis zoo. Piv txwv li, compounding ePTFE membrane nrog waterproof fabrics xws li nylon thiab polyester tuaj yeem siv los ua cov khaub ncaws sab nraum zoov, tsev pheeb suab, thiab lwm yam.
Kev sib xyaw nrog lwm cov ntaub ntawv polymer: Compounding ePTFE membrane nrog rau lwm cov ntaub ntawv polymer, xws li polyurethane, acrylate, thiab lwm yam, tuaj yeem txhim kho kev ua haujlwm ntawm daim nyias nyias. Piv txwv li, compounding ePTFE daim nyias nyias nrog polyurethane tuaj yeem txhim kho qhov hnav tsis kam thiab tshuaj tiv thaiv corrosion ntawm daim nyias nyias thaum tuav cov dej tsis zoo.
Tsis tas li ntawd, thaum siv ePTFE membrane, koj yuav tsum tau them sai sai rau cov ntsiab lus hauv qab no:
Tsis txhob muaj kev puas tsuaj rau daim nyias nyias: ePTFE daim nyias nyias yog qhov tsis yooj yim thiab yooj yim puas los ntawm kev puas tsuaj, xws li khawb thiab punctures. Thaum siv, daim nyias nyias yuav tsum tau tiv thaiv los ntawm kev sib cuag nrog cov khoom ntse los tiv thaiv cov membrane los ntawm kev puas tsuaj thiab cuam tshuam rau cov dej tsis zoo.
Kev tshuaj xyuas thiab kev saib xyuas tsis tu ncua: Tsis tu ncua xyuas kev siv ntawm ePTFE membrane, xws li seb puas muaj teeb meem xws li kev puas tsuaj thiab kev laus. Yog tias pom muaj teeb meem, lawv yuav tsum tau kho lossis hloov lub sijhawm kom ntseeg tau tias cov dej tsis zoo ntawm daim nyias nyias.
Xaiv ib puag ncig zoo siv: Cov dej tsis zoo ntawm ePTFE daim nyias nyias yuav txawv raws li ib puag ncig sib txawv. Thaum xaiv ib puag ncig siv, qhov tsim nyog ib puag ncig yuav tsum raug xaiv raws li cov yam ntxwv ntawm kev ua tau zoo thiab cov kev xav tau tiag tiag ntawm daim nyias nyias los muab kev ua si tag nrho rau cov dej tsis zoo ntawm daim nyias nyias.
