PTFE O-Ringi

I-Polytetrafluoroethylene (PTFE) yipolymer enobunzima bemolekyuli ephezulu, enye yezona mathiriyeli zininzi zeplastiki ezaziwa kwaye ziluncedo kuluhlu olukhulu lweemveliso zosetyenziso olungabandakanywa kwezinye izinto.

I-Polytetrafluoroethylene (i-PTFE ngokufutshane) yirabha yokwenziwa kwe-friction ephantsi ekudala isetyenziselwa ukufakwa kwe-sealant kwizinto ezahlukeneyo ezibandakanya igesi, ulwelo kunye neekhemikhali.

PTFE O-Ring Uluhlu lobushushu

Nangona i-PTFE ineempawu ezisezantsi zoomatshini xa kuthelekiswa nezinye iiplastiki, ukuxhathisa kweekhemikhali zezinto eziphathekayo ngokuhambelana nokukwazi ukumelana noluhlu olubanzi lobushushu (-100oF ukuya + 400oF) vumela i-PTFE o-rings ukunika ukuxhathisa okusebenzayo kwimozulu kunye nombane kunye ne-thermal. ukugquma.

Ngenxa yokuba i-PTFE iyimathiriyeli eshinyene ngolo hlobo, ayinaku “nyibilika iqhubekeke” - kufuneka icinezelwe kwaye ifakwe i-sintered ukwenza iimilo eziluncedo (njenge-o-rings).
