Nā noi o PTFE Rod

PTFE RodNā hiʻohiʻona: He ākea loa ka pae wela o ka hoʻohana ʻana (Celsius mai - 200 degere a +260 degere);ʻO ka corrosiveness o nā mea kemika anti-majority, koe wale nō kekahi mau fluorides a me alkalinity moltenmetal; ʻO nā waiwai mechanical maikaʻi loa, ke kū ʻana o ka wā kahiko; Kūʻē ahi maikaʻi loa (E like me ka ASTM-D635 a me D470 test step), i ka lewa e hoʻoponopono ʻia ma ke ʻano he mea pale ahi; Haʻahaʻa loa. hoʻopaʻa wai……

Ua ʻike ʻia ʻo PTFE-polytetrafluoroethylene e Kauka Roy Plunkett o DuPont Research Laboratory ma ʻApelila 6, 1938. Ua hoʻomohala hou ʻia ka PTFE mua e Dupont a hoʻokuʻu ʻia ma ke ʻano he huahana ma 1945.

He kū'ē loa ka huahana i ka ʻino kemika a hiki ke mālama i nā mahana ma luna o 500 ° C. ʻO kekahi o nā mea hale mua o PTFE ʻo ia ka "PTFE coated frying pan".ʻOiai ke hana maikaʻi nei ka ipuhao, ʻokoʻa ia mai nā lāʻau PTFE a me nā papa a mākou e hoʻolako ai.Hoʻopili ʻia ʻo ia ma kahi ʻeleʻele ʻeleʻele, nā koʻokoʻo PTFE maʻemaʻe a me nā ʻāpana i loko o ka PTFE pōʻai pahu pahu pahu pahu he keʻokeʻo keʻokeʻo pehea e hoʻohana ai i nā ʻoihana PTFE plastik koʻokoʻo pehea e hoʻohana ai i ka ʻoihana PTFE plastik koʻokoʻo PTFE gaskets a me ka pahu pahu.

No ka mea he kiʻekiʻe ka wela o ka PTFE a me ke kūpaʻa kemika, hoʻohana maʻamau ia no nā noi valve.Mai nā ʻauwaʻa mahu / wai wela a hiki i ka wela kiʻekiʻe, nā ʻoihana lawelawe ʻana i ka wai i nā kiwi kemika.ʻO kēia mea he semi-rigid i ka plastic plastic a hiki ke maʻalahi i ka mīkini - kekahi o ka mea maʻalahi loa e hoʻohana i ka plastic.Hiki ke hoʻohana ʻia ke koʻokoʻo PTFE i loko o nā tolerances kokoke loa i ka nui o nā koʻokoʻo anawaena liʻiliʻi me ke anawaena o +.002 “/ — .00”.ʻO ke kūpaʻa kemika kekahi o nā waiwai nui e pili ana i nā mea.I nā flakes a i ʻole flakes, hoʻohana ʻia ka PTFE ma ke ʻano he gasket mea no ka wela kiʻekiʻe a me nā flanges a me nā sila.
