Raw Material Purity cuam tshuam li cas rau kev ua haujlwm ntawm PTFE High-Temperature Cloth

PTFE high-temperature ntaub (PTFE-coated fiberglass) tsuas yog zoo li cov ntaub ntawv raw siv los ua nws. Thaum PTFE yog inherently ib tug high-kev ua tau zoo polymer, impurities nyob rau hauv lub molecular theem yuav dramatically degrade nws cov khoom.

'Raw khoom purity' ntawm no yog hais txog ob yam: kev huv ntawm PTFE raw cov ntaub ntawv (cov residual initiators, surfactants, low-molecular-yuag polymers, hlau ions) thiab kev huv si ntawm fiberglass tiav cov neeg ua hauj lwm (sizing, lubricants, contaminants los ntawm weaving).

Aokai PTFE xaiv tsuas yog high-purity raw cov ntaub ntawv. Kab lus no piav qhia txog yuav ua li cas impurities cuam tshuam rau 6 qhov tseem ceeb ntawm kev ua tau zoo: tshav kub tsis kam, cov khoom tsis-stick, hluav taws xob rwb thaiv tsev, txhua yam muaj zog, zoo li, thiab tshuaj lom neeg kev nyab xeeb.

Thaum tshav kub kub Resistance thiab Thermal Stability - Impurities Accelerate degradation

Thaum tshav kub kub tsis kam yog qhov qhia txog kev ua haujlwm tseem ceeb ntawm cov ntaub kub kub.

1. Cov impurities ua rau thaum ntxov thermal decomposition

Residual initiators, low-molecular-weight polymers, thiab incompletely cleaned surfactants feature low thermal decomposition temperatures than pure PTFE. Nyob rau hauv lub sij hawm ntev kev pab cuam kub kub (xws li, 260 ° C), cov impurities decompose thiab carbonize ua ntej, generating gas uas ua rau npuas, pinholes, blistering, thiab delamination nyob rau hauv lub txheej.

2. Txo qhov kub thiab txias tsis tu ncua

Acid los yog alkaline byproducts los ntawm decomposed impurities yuav ntxiv catalyze lub cleavage ntawm PTFE molecular nraub qaum, txo qhov tseeb kub kuj ntsuas ntawm daim ntaub thiab drastic shortening nws cov kev pab cuam lub neej. Tsuas yog cov khoom siv purity siab ua kom muaj kev ruaj ntseg mus ntev hauv 260 ° C txog 300 ° C.

Aokai PTFE cov ntaub ntawv xeem: PTFE daim ntaub ua los ntawm cov qauv-qib emulsion qhia pom daj tom qab 100 teev ntawm 260 ° C. Cov ntaub ua los ntawm high-purity emulsion tseem tsis hloov tom qab 500 teev ntawm qhov kub thiab txias.

Non-Stick Property and Surface Characteristics – Uniform Surface Energy

Kev ua haujlwm tsis zoo yog qhov tseem ceeb ntawm kev ua haujlwm zoo ntawm PTFE cov ntaub ntawv kub.

1. Tsis sib luag nto zog faib

Cov yam ntxwv uas tsis yog-stick ntawm PTFE muab los ntawm nws lub zog ultra-low nto. Yog hais tias inorganic hais, unmelted resin impurities, los yog roj paug muaj nyob rau hauv raw cov ntaub ntawv, lawv yuav embed on los yog nyob rau hauv lub txheej tom qab sintering, tsim uneven lub zog nto thiab tsim adhesion anchor ntsiab lus..

2. Kev ua haujlwm tsis zoo ntawm kev ua haujlwm tsis zoo

Cov khoom ua haujlwm xws li cov nplaum nplaum thiab cov khoom xyaw zaub mov yuav ua raws li pib los ntawm cov ntsiab lus thauj tog rau nkoj thiab nws thiaj li tsim cov chaw sib txuas loj thaum lub sijhawm ua haujlwm. Cov khoom siv raw purity siab dua muab cov txheej txheem ntau dua thiab ntom ntom nrog kev tso tawm zoo dua thiab cov teebmeem los tiv thaiv.

Hluav taws xob rwb thaiv tsev Performance - Ionic impurities yog tus nqi nqa

Purity yog qhov txiav txim siab rau cov ntaub ntawv kub kub uas siv los ua hluav taws xob rwb thaiv tsev mats.

1. Ntse nce hauv dielectric poob

Ionic impurities suav nrog cov hlau ions, ntsev, thiab cov khoom seem seem ua haujlwm raws li cov neeg nqa khoom, ua kom cov dielectric tsis tu ncua thiab dissipation yam tseem ceeb thaum txo qhov ntim resistivity. Qhov no degrades rwb thaiv tsev efficiency.

2. Txo qhov hluav taws xob tawg

Conductive contaminants xws li hlau scraps thiab carbonized me ntsis concentrates hluav taws xob teb thiab induce ib feem tawm, uas drastic txiav down breakdown voltage. High-purity PTFE yog qhov yuav tsum tau ua kom muaj kev rwb thaiv tsev zoo nyob rau hauv high-frequency thiab high-voltage ua hauj lwm tej yam kev mob.

Mechanical Strength thiab Flexibility - Kev ntxhov siab ntawm qhov chaw tsis huv

1. Tsim cov ntsiab lus kev ntxhov siab

Hard impurity hais thiab unplasticized resin agglomerates ua txhaum lub continuation ntawm txheej. Raws li rov khoov thiab ncab, cov kab nrib pleb nyiam tsim thiab nthuav tawm ntawm cov ntsiab lus tsis muaj zog, ua rau txo lub zog tensile thiab luv luv flex resistance lifespan.

2. Deteriorated txheej adhesion

Cov residual surfactants ntau dhau ua rau lub zog sib txuas ntawm PTFE thiab fiberglass npuag, ua rau lub zog tev tsis txaus. Coatings ua los ntawm high-purity tag nrho molten PTFE feature compact kev ntxhib los mos thiab zoo saj zawg zog, ua tawv thiab check high-temperature ntaub.

Xim thiab tsos - Yellowing yog ib tug Purity ceeb toom kos npe

Ntshiab PTFE yog ib txwm milky dawb thiab semi-pob tshab. Yellowing, feem ntau nto defect ntawm PTFE high-temperature daim ntaub, feem ntau stems los ntawm ntau impurities nyob rau hauv raw cov ntaub ntawv:

• Hlau xeb thiab hlau tsis huv

• Organic residues

• Cov tshuaj nquag carbonization hauv qab cua sov

Rau kev ua zaub mov, kev kho mob, thiab high-end electronics daim ntawv thov nrog cov qauv kev huv huv, raw khoom purity ncaj qha txiav txim siab seb cov khoom tiav tuaj yeem ua tiav qhov zoo nkauj dawb huv thiab ua tau raws li cov kev cai tsis muaj paug.

Chemical Stability thiab Sanitary Safety – Leaching Risks

Pure PTFE tiv thaiv corrosion los ntawm yuav luag txhua yam tshuaj. Txawm li cas los xij, soluble impurities nyob rau hauv lub txheej yuav erode thaum raug cov acids muaj zog, muaj zog alkalis, los yog organic solvents, ua rau txheej o thiab permeation.

Hauv kev ua zaub mov, kev tsim tshuaj, thiab kev siv cov khoom siv semiconductor, taug qab cov khoom tsis zoo (xws li cov qub qub PFOA seem) hauv cov ntaub ntawv raw khoom muaj kev pheej hmoo ntawm cov tshuaj leaching . Tsuas yog high-purity zaub mov-qib thiab kev kho mob-qib raw cov ntaub ntawv ua raws li FDA, EU, thiab cov txheej txheem kev tswj xyuas muaj feem xyuam rau kev siv tsis muaj tshuaj lom thiab nyab xeeb.

Summary - Purity Sets the Performance Ceiling

Raw khoom purity ncaj qha tswj hwm tsib qhov kev ua tau zoo ntawm PTFE daim ntaub kub kub:

Cov teeb meem tshwm sim los ntawm ib qho impurity yuav downgrade high-performance PTFE ntaub rau zoo tib yam low-grade ntaub.

Aokai PTFE tsuas yog siv high-purity PTFE emulsion thiab huv si fiberglass substrates. Peb muab cov ntaub ntawv purity cov ntaub ntawv, suav nrog FDA daim ntawv pov thawj kev ua raws cai thiab kev tshuaj xyuas cov hlau hnyav, thaum thov.
