PTFE high-temperature daim kab xev yuav tsum tau cia kom zoo kom nws adhesion, yooj, thiab tso tawm kev ua tau zoo. Cov kev cai tseem ceeb suav nrog kev tswj qhov kub thiab txias (10-30 ° C), cov av noo qis dua 60%, kev zam lub teeb, kev cais tshuaj lom neeg, qhov chaw ntsug, thiab qhov cua. Ua raws li FIFO kev tswj cov khoom muag thiab tshuaj xyuas tsis tu ncua.

Xaiv txoj cai PTFE high-temperature daim kab xev rau 3D tshuab luam ntawv kub txaj yuav tsum tau tsom rau plaub qhov tseem ceeb qhia: kub tsis kam (txog 260 ° C +), fiberglass-reinforced substrate (0.18mm zoo tagnrho), silicone nplaum rov qab nrog uas tsis yog-stick saum npoo, thiab kom dav / kam rau ua. Cov lus qhia no pab koj kom tsis txhob muaj kev sib tsoo, qhov seem, thiab luam tawm tsis ua haujlwm.

Cov iav hloov pauv kub (Tg) ntawm silicone siab-rhiab nplaum nplaum yog nyob ib ncig ntawm -120 ° C - qis dua li acrylic nplaum. Qhov no ultra-low Tg khaws PTFE high-temperature daim kab xev hloov tau yooj yim thiab nplaum txawm nyob rau ntawm -70 ° C, tiv thaiv nkig tawg thiab ua kom muaj kev ruaj ntseg adhesion hauv cov ntawv thov cryogenic.

PTFE high-temperature daim kab xev tuaj yeem tawg los yog tawg nyob rau hauv rov khoov thiab qhib tej yam kev mob. Kab lus no piav qhia yuav ua li cas tiv thaiv qhov no los ntawm kev xaiv cov substrate kom zoo (iav fiber ntau reinforced), pom thickness (0.18mm raws li tus qauv), silicone nplaum xaiv, thiab cov txheej txheem installation kom raug.

PTFE high-temperature npuag muaj cov tshuaj tiv thaiv tshwj xeeb, tiv taus cov kua qaub, alkalis, cov kuab tshuaj organic, thiab corrosive gases. Tsab ntawv xov xwm no qhia txog nws cov tshuaj tiv thaiv, kev txwv (molten alkali hlau, muaj zog fluorinating cov neeg ua haujlwm), thiab cov ntsiab lus tseem ceeb xws li kub, concentration, thiab kev ntxhov siab.

Kev xaiv ntawm cov ntawv tso tawm lossis zaj duab xis substrate thiab tso tawm tus neeg sawv cev ncaj qha cuam tshuam rau kev ruaj khov thiab kev ua haujlwm ntawm PTFE cov kab xev kub kub. Kab lus no sib piv PET vs. kraft daim ntawv substrates thiab silicone vs. fluorinated tso cov neeg ua haujlwm, pom zoo ua ke kom zoo rau xoom-residue tev thiab kev ntseeg tau ntev.

PTFE high-temperature tapes yog dav siv rau hluav taws xob rwb thaiv tsev, tab sis high-frequency thiab high-voltage tej yam kev mob ua rau muaj kev pheej hmoo tshwj xeeb: hluav taws xob tawg, ib nrab paug, thermal aging, high-frequency teeb liab poob, thiab ib puag ncig rhiab heev. Kab lus no piav qhia txhua qhov kev pheej hmoo thiab yuav ua li cas zam lawv.

PTFE impregnation tsis txwv rau fiberglass daim ntaub. Kab lus no qhia txog 7 lwm cov substrates - aramid, carbon fiber, PBI, ntxeem tau hlau, graphite, asbestos (phased tawm), thiab ceramic fillers - nrog lawv cov txheej txheem nta, zoo, kev txwv, thiab cov ntawv thov tseem ceeb.

Ua pa PTFE siab kub ntaub ua ke nrog cov khoom tsis-stick, thermal stability, thiab huab cua permeability. Kab lus no tshawb txog nws cov ntawv thov tseem ceeb hauv kev ziab khaub ncaws, kev ua zaub mov, kev tsim khoom sib xyaw, khoom siv hluav taws xob, pneumatic conveying, kev tiv thaiv ib puag ncig, thiab cov khoom siv hauv tsev.

Kab lus no piav qhia txog yuav ua li cas tiv thaiv kev kis kab mob thiab kev ua haujlwm puas tsuaj ntawm sab tsis-nplaum ntawm PTFE daim kab xev kub kub thaum txheej txheem txheej. Cov tswv yim tseem ceeb muaj xws li kev tswj hwm qhov chaw (txhim kho qhov chaw), kev sib cais ntawm lub cev (cov yeeb yaj kiab tiv thaiv, cov yob tsis lo, zoned ziab), thiab kev tswj cov txheej txheem ua kom zoo.
