Cov nyhuv ntawm kub ntawm PTFE cov ntaub ntawv

PTFE cov khoom yog ua los ntawm cov khoom siv PTFE los ntawm molding thiab lwm cov txheej txheem tshwj xeeb ua thiab tsim cov khoom, nrog cov yam ntxwv ntawm PTFE cov ntaub ntawv, xws li siv ntau qhov kub thiab txias (-200 ℃ ~ +260 ℃), cov tshuaj lom neeg tiv taus ntau yam kev txhim kho corrosion, tsis-lo, tsis tshua muaj kev sib txhuam coefficient, cov khoom siv hluav taws xob zoo heev, tsis muaj tshuaj lom, tsis muaj teeb meem kev laus, thiab lwm yam Nws tuaj yeem sau lub ntsiab lus hauv ib kab lus, uas yog: kev ua yeeb yam ntawm PTFE cov khoom muaj feem cuam tshuam nrog kev ua haujlwm thiab kev thov thiab qhov zoo ntawm PTFE cov khoom lag luam nyob rau theem tom ntej, yog li cia' s ua tibzoo saib cov khoom siv PTFE thiab cuam tshuam hauv yam.

Raws li cov ntawv ua cov thermoplastic polymer, PTFE yog rhiab rau kev ntsuas ib puag ncig. Hauv qhov kub thiab txias txawv, qhov kev ua tau zoo ntawm tib ntu sib txawv, qhov tshwm sim ntawm elongation thaum so yuav hloov ntau thaum kub poob los ntawm ntau qib hauv qhov ntsuas tensile, thiab qee zaum txawm tias qhov kev ntsuas ntsuas no yuav raug txiav txim tias tsis muaj qhov tsis tsim nyog. Yog li, chav ntsuas kub ntawm chav kuaj yuav tsum muaj kev tswj hwm nruj, tom qab sintering ntawm lub disc ntawm 23+2 ℃ rau kev kho lub xeev, nrog rab riam xuas nrig rau hauv tus qauv dumbbell zoo li tus qauv, tib lub qauv tuab tsis sib txawv tsis ntau tshaj +0.1mm, txhua pawg ntawm cov qauv yuav tsum tsis pub tsawg tshaj 5, thiab tom qab ntawd siv lub tshuab kuaj ntsuas ntawm nrawm ntawm 100mm / min + 10mm / min, raws li phau ntawv ua haujlwm ntsuas phau ntawv, txhawm rau txhawm rau nrhiav qhov elongation thaum tawg ntawm PTFE cov khoom Cov.
