Yuav tsum tau ua kom txias npaum li cas thaum sintering ntawm PTFE High-Temperature Ntaub

I. Yam yuav tsum tau muaj rau tus nqi cua txias

Kev nrawm dhau los ntawm thaj chaw crystallization-rhiab heev Lub melting point ntawm PTFE yog 327 ° C, thiab tus qauv sintering kub ntawm 380 ° C mus rau 400 ° C. Thaum lub sij hawm txo qhov kub thiab txias, qhov tseem ceeb yuav tsum tau ceev nrooj hla thaj tsam kub ib ncig ntawm 310 ~ 315 ° C qhov twg crystallization tus nqi peaks sharply.

Txoj kev ua haujlwm pom zoo Tam sim ntawd tom qab tawm ntawm lub qhov cub sintering, siv cov cua txias, compressed cua tshuab cua txias, lossis siv cov cua txias / dej txias kom ceev cov ntaub kub hauv qab 250 ° C.

 

Kev siv cov ntsuas ntsuas cua txias Raws li cov khoom tuab, cov cua txias dav dav yuav tsum tsis pub tsawg dua 30 ~ 50 ° C / min. Rau nyias-gauge high-temperature daim ntaub (0.08mm ~ 0.25mm), cua txias tuaj yeem ua tiav qhov txias tshaj li 100 ~ 200 ° C / min, ua kom muaj kev nkag mus sai sai los ntawm thaj chaw crystallization tseem ceeb.

 

II. Txheej Txheem Txheej Txheem: Yuav ua li cas txias tus nqi cuam tshuam cov khoom lag luam

Crystallinity txiav txim siab cov khoom tseem ceeb ntawm cov khoom cua txias hom ncaj qha tswj cov crystallinity ntawm PTFE, uas ntxiv dictates cov yam ntxwv tseem ceeb ntawm txheej nrog rau kev yooj yim, adhesion thiab tsis-stick kev ua tau zoo.

 

Kev sib piv ntawm kev ua haujlwm nrawm thiab qeeb qeeb

Microstructural Piav Qhia Kev txias ceev ceev txwv txoj kev loj hlob ntawm qhov loj-loj spherulites thiab tsim cov qauv zoo microcrystalline. Qhov no ua rau PTFE zaj duab xis denser thiab ntau dua, thaum txo qis kev ntxhov siab ntawm cov txheej thiab fiberglass substrate.

 

III. Cov ntsiab lus tseem ceeb hauv kev tsim khoom loj

 

Guarantee uniform txias txias cua txias los yog txias rollers yuav tsum tswj qhov kub thiab txias nyob rau hauv daim ntaub dav. Tsis sib npaug zos crystallinity yuav ua rau mottled nto los yog wrinkling tsis xws luag.

 

Tsis txhob muaj thermal poob siab rau cov ntaub tuab tuab (0.5 hli thiab siab dua), cov dej ncaj qha los yog kev sib cuag nrog cov menyuam txias txias tuaj yeem ua rau muaj qhov deformation loj heev los ntawm kev sib txuam thermal shrinkage ntawm substrate thiab txheej. Ib qho kev ua haujlwm zoo dua yog cua txias kom qis dua 250 ° C ua ntej txias ntxiv.

 

Kev tswj cua txias rau ntau dhau sintering Rau ntau qhov impregnation & multi-sintering txheej txheem, nruab nrab ceev txias yog siv tau rau nruab nrab sintering cycles. Txawm li cas los xij, qhov kawg ntawm qhov sintering kauj ruam yuav tsum tau txais kev ua kom txias sai kom ruaj ntseg qhov chaw ua haujlwm zoo.

IV. Cov ntsiab lus tseem ceeb

1. Kev ua kom txias sai yog qhov yuav tsum tau ua tom qab PTFE daim ntaub sintering kom ua kom PTFE molten hla qhov kub-kub crystallization tsam sai.

2. Kev ua kom txias sai sai ua rau cov qauv qis-crystallinity microcrystalline, uas yog tus yuam sij rau kev ua tau zoo, quav tsis kam thiab ua haujlwm ntev ntev.

3. nruj me ntsis tswj cov cua txias uniformity, tiv thaiv thermal poob siab, thiab standardize txias lub sij hawm rau ntau theem sintering kom stabilize cov khoom zoo ib yam.
