O-rings

PTFE O-rings ubedo piny ma juku kudu ma nen calu toroidal (ma calu donut), ma juyike maber ku PTFE mi mio dhugola maber man ma jukutho ku kemikol i tic matung tung mi tic. Ni tiyo ku kit ma PTFE utiye kudu, O-rings eni gibedo piny maber uloyu ka jutiyo ku kabedo ma kemikol ma tek, lyethu ma tek, man tic ma mitu friction manok man leng pa piny.

Kidi ma pire tek pa tic pa PTFE O-ring utiye i bedo pa kemikol ma ber pa piny ne. PTFE nyuthu kero ma romo ikum lwiny pa kemikol, man ebedo ma epe ku kemikol mi tic, solvents, acids, man bases. Eni weko PTFE O-rings bedu piny ma pire tek in tic macalo tic mi kemikol, yath, man oil man gas, kama bedo i iye piny ma nyai. Ker migi mi gwoko bedoleng migi i thenge mi lembe ma tek eno ketho gibedo ma rii pi kare malac, ma epe ku pii man eketho bedo maber man gen pa jam tic ma pire tek.

Bende, PTFE O-rings utiye ku rwom ma lac mi tic, ma romo -200°C nitundo +260°C (-328°F nitundo +500°F). Ker pa lyethu ma dit eni weko gi timo tic maber i tic mi cryogenic man high-temperature, ma miyo tic maber mi gwoko piny i lembe matung tung. Coefficient ma piny pa friction ma nwangre i PTFE dwoko piny peko mi mako nyo galling i saa mi coko man tic, man de dwoko piny rwinyo pa O-ring man mating surfaces, ma medo kwo pa tic man bedo yot mi gwoko.

PTFE O-rings nwango tic ma lee i tic mi ketho piny ma nyai man ma nyai i kabedo matung tung, ikinde utiye aerospace, mutukari, cam man kongo, jam yath, man semiconductor manufacturing. Kadi bende PTFE ma nyen mio kero maber mi gwoko piny, PTFE ma juloko nyo ma jupongu de utiye. Jam tic eni uketho i iye piny moko macalo glass fibers, carbon, graphite, nyo bronze mi medo piny moko macalo kero mi rwinyo, kero mi rwinyo i the tic, man kero mi tero lyethu, ma dwoko tic pa O-ring ni piny ma mitere nyo ma pire tek. Yer pa PTFE maber man O-ring design piretek pi bedo ku tic maber man kwo pi kare malac i tic ma juyike.
