Processing thiab Application of PTFE Micropowder
Polytetrafluoroethylene (PTFE) micropowder yog cov khoom siv dawb, nplua zoo tau los ntawm qhov hnyav molecular PTFE. Nws tuaj yeem siv los ua cov khoom siv ntxiv hauv cov yas, inks, coatings, lubricants, thiab greases los txhim kho cov tsis muaj nplaum thiab hnav tsis kam ntawm cov khoom siv hauv paus. Nws kuj tseem siv tau ib leeg los txhim kho ntau yam khoom.
PTFE micro hmoov yog ib qho tseem ceeb ntawm cov khoom siv, thiab nws txoj kev ua thiab daim ntawv thov yuav tsum tau ua tib zoo saib rau ntau lub ntsiab lus:
Txheej txheem txheej txheem
(1) Compression molding: compress PTFE micro-hmoov rau hauv ntau yam duab xws li daim hlau, rods, raj, thiab lwm yam ntawm qhov kub thiab txias, ua raws li kev ua haujlwm ntxiv.
(2) Txhaj tshuaj molding: tso PTFE micro-hmoov rau hauv lub tshuab txhaj tshuaj molding thiab pwm nws mus rau ntau qhov chaw ntawm qhov kub thiab txias.
(3) Extrusion molding: tso PTFE micro-hmoov rau hauv lub tshuab extrusion thiab ua nws rau hauv ntau yam duab xws li cov xov hlau thiab cov blocks nyob rau hauv qhov kub thiab txias.
(4) Cua sov molding: tso PTFE micro hmoov rau hauv pwm, kub nws mus rau qhov kub thiab txias kom yaj thiab pwm nws.
Cov Tswvyim rau Kev Siv
(1) Txheej: PTFE micro-powder tuaj yeem siv los ua cov tshuaj ntxiv hauv cov txheej txheem los txhim kho lawv cov kev ua tau zoo. Ntxiv rau ntau yam khoom, xws li plastics, inks, coatings, thiab lwm yam, tuaj yeem txhim kho lawv cov hnav tsis kam, corrosion resistance, lubrication, thiab ua kom lawv lub neej ntev. Hauv txheej txheej txheej txheej, PTFE micro-hmoov yuav tsum tau muab sib xyaw nrog lwm cov khoom kom tsis txhob muaj lumping lossis tsis sib luag.
(2) Txhaj thiab extrusion: thaum lub sij hawm txhaj tshuaj thiab extrusion txheej txheem, PTFE micro-hmoov yuav tsum tau muab sib xyaw nrog lwm cov ntaub ntawv kom ntseeg tau tias cov khoom muaj toughness txaus thiab lub zog. Nyob rau tib lub sijhawm, kub thiab siab yuav tsum tau tswj kom tsis txhob muaj cov khoom deformation lossis puas.
(3) Kev ua thiab kev kho deg: thaum lub sij hawm ua PTFE micro-hmoov, chips thiab txiav kua yuav raug tsim, uas muaj teeb meem rau tib neeg noj qab haus huv. Yuav tsum muaj kev tiv thaiv zoo sib xws. Tsis tas li ntawd, kev kho saum npoo yog xav tau tom qab ua tiav los txhim kho qhov zoo thiab zoo ntawm cov khoom.
(4) Daim ntawv thov teb: PTFE micro-powder muaj ntau daim ntawv thov depending ntawm nws cov yam ntxwv sib txawv. Hauv kev lag luam thiab kev lag luam aerospace, feem ntau yog siv los tsim cov khoom xws li fuselages, engines, thiab propulsion systems. Hauv kev lag luam hluav taws xob, nws tau dav siv los tsim cov khoom siv hluav taws xob xws li cov xov hlau, cov khoom siv hluav taws xob, thiab cov resistors. Hauv kev lag luam tshuaj thiab zaub mov, PTFE micro-powder kuj muaj ntau yam kev siv, xws li hauv kev tsim cov khoom siv lub plawv li qub thiab ntim khoom noj.
Hauv kev xaus, PTFE micro hmoov yog cov khoom siv tseem ceeb, thiab nws txoj kev ua haujlwm thiab kev siv yuav tsum tau ua tib zoo saib xyuas qhov kub, siab, sib tov, thiab lwm yam. Tsuas yog los ntawm kev paub txog cov ntsiab lus technical no tuaj yeem ua tau zoo PTFE micro-hmoov cov khoom raug tsim thiab siv rau kev lag luam thiab kev lag luam sib txawv.
