PTFE Nonwoven Npuag

I. Cov yam ntxwv tseem ceeb ntawm PTFE Non-woven Fabric: Tus "Vaj Ntxwv ntawm Kev Tiv Thaiv Huab Cua" hauv Cov Chaw Ib puag ncig hnyav

PTFE tsis-woven ntaub, vam khom qhov zoo ntawm PTFE khoom thiab cov yam ntxwv ntawm spunlace txheej txheem, tsim peb lub ntsiab nta, tawg los ntawm kev ua tau zoo ntawm cov organic thiab inorganic fibers hauv corrosive heev, ultra-siab kub thiab siab-huv scenarios:

1. Kev xeb thiab kev tiv taus kub ntawm txhua qhov xwm txheej: Lub "armor uas tsis tawg tau" rau cov khoom siv hnyav

Kev tiv thaiv xeb ntau dua li txhua yam khoom siv Tsis zoo li aramid (tiv taus qee cov kua qaub thiab alkalis) thiab basalt (tiv taus cov kua qaub thiab alkalis tab sis ntshai fluorides), PTFE tsis muaj kev cuam tshuam nrog yuav luag txhua yam tshuaj lom neeg paub (xws li aqua regia, concentrated nitric acid, hydrofluoric acid, thiab cov oxidants muaj zog). Tom qab ntub rau 100 hnub, qhov poob ntawm lub zog tawg yog ≤1%. Hauv cov xwm txheej corrosive heev xws li kev tsim tshuaj lom neeg, electroplating, thiab tshuaj, nws lub neej kev pabcuam tuaj yeem ncav cuag ntau dua 10 xyoo. Nws yog 5 txog 8 npaug ntawm cov khoom siv tiv thaiv xeb ib txwm muaj.

Qhov kub thiab txias dav dav ruaj khov yam tsis muaj kev txo qis Nws tuaj yeem ua haujlwm ruaj khov rau lub sijhawm ntev hauv qhov ntau ntawm -200 ℃ (kub qis heev) txog 260 ℃ (kub siab), thiab tuaj yeem tiv taus qhov kub luv luv txog li 300 ℃. Txawm tias tom qab spunlace reinforcement, nws tseem khaws cia qhov kub thiab txias qub ntawm cov khoom siv, daws cov teeb meem ntawm cov organic fibers (xws li polyester thiab polypropylene) yooj yim yaj ntawm qhov kub siab thiab cov inorganic fibers (xws li basalt) yooj yim tawg ntawm qhov kub qis. Nws yog qhov tsim nyog rau qhov kub thiab txias heev xws li thaj chaw txias heev thiab kev lag luam kub siab.

2. Tsis lo thiab tiv thaiv kev qias neeg + kev sib txhuam tsawg: Tus "Tus qauv ntxuav tus kheej" hauv cov xwm txheej huv si

Qhov tshwj xeeb ntawm PTFE uas tsis lo rau saum npoo yog: Lub zog ntawm PTFE uas tsis lo rau saum npoo yog qis heev (tsuas yog 18mN/m2), thiab nws tsis lo rau cov khoom siv (xws li cov roj pleev, cov resins, thiab cov kua nplaum). Cov xim pleev yooj yim so tawm yam tsis tas ntxuav ntau zaus, daws qhov teeb meem ntawm cov ntaub tsis-woven ib txwm uas "yooj yim lo thiab nyuaj ntxuav". Nws yog qhov tshwj xeeb tshaj yog rau cov xwm txheej uas yooj yim lo, xws li kev ua zaub mov thiab kev luam ntawv.

Kev sib txhuam tsawg thiab txo qhov poob: Nrog rau kev sib txhuam coefficient ntawm tsuas yog 0.04 (dynamic friction coefficient), nws yog qhov qis tshaj plaws ntawm cov khoom siv khov kho. Qhov hnav tsis tshua muaj thaum sib cuag nrog lwm yam khoom. Hauv cov xwm txheej sib txhuam zaus siab xws li cov siv conveyor thiab cov foob, nws lub zog ruaj khov yog ntau dua 10 npaug ntawm nylon thiab polyurethane cov ntaub ntawv, txo cov nqi hnav khoom siv.

3. Kev Huv Si Siab + Kev Ua Haujlwm Yooj Yim: Lub "Hloov Kho Lub Hauv Paus" rau Kev Kho Kom Zoo Nkauj Siab

Kev huv si sab hauv yam tsis muaj kev hloov pauv: Cov khoom siv PTFE tsis muaj cov khoom ntxiv (xws li cov yas thiab cov khoom ruaj khov). Nyob rau hauv qhov kub thiab txias siab, tsis muaj cov tshuaj lom neeg hloov pauv, thiab nws tsis tsim cov hmoov av lossis cov fiber poob los ntawm nws tus kheej. Nws ua tau raws li cov kev cai huv si siab xws li kev sib cuag zaub mov (Daim ntawv pov thawj FDA) thiab kev kho mob kom huv si (GMP cov qauv), ua rau nws yog cov khoom siv huv si nyiam hauv cov khoom siv semiconductor thiab cov tshuaj.

Cov txheej txheem spunlace khaws cia qhov yooj ywm: Los ntawm kev siv cov dej siab siab jet flexible entanglement, nws zam kev puas tsuaj rau cov fibers los ntawm cov txheej txheem needling. Cov khoom tsis yog tsuas yog muaj qhov rigidity ntawm PTFE khoom tab sis kuj tswj nws cov yam ntxwv mos thiab foldable. Nws tuaj yeem txiav, xaws, thiab kub-nias rau hauv txhua yam duab (xws li sealing gaskets thiab lim hnab), daws qhov kev txwv ntawm PTFE phaj ua "nyuaj, brittle thiab nyuaj rau ua", thiab yog tsim rau ntau yam kev xav tau customization.

II. Cov teb tseem ceeb ntawm PTFE cov ntaub tsis-woven: Ib qho kev daws teeb meem tsis tuaj yeem hloov pauv rau cov xwm txheej siab kawg

Raws li cov yam ntxwv tseem ceeb saum toj no, PTFE tsis-woven ntaub tau dhau los ua "cov khoom siv yuav tsum muaj" hauv cov teb xws li tshuaj tiv thaiv xeb, kev huv huv hluav taws xob, khoom noj thiab kev kho mob, thiab kev lag luam siab, tsim nyog rau cov xwm txheej tseem ceeb nrog cov kev xav tau siab, kev pheej hmoo siab, thiab kev huv huv siab.

1. Kev tsim kho tshuaj lom neeg thiab kev tiv thaiv ib puag ncig: Lub zog "Tiv thaiv xeb" hauv cov xwm txheej corrosive heev
