Mea holoi PTFE ka nui kala maʻamau

ʻO ka polytetrafluoroethylene apo PTFE kekahi o nā mea kū'ē i ka corrosion maikaʻi i ka honua i kēia lā, no laila e loaʻa i ka inoa o ka "plastic King". Hiki ke hoʻohana ʻia i kēlā me kēia ʻano mea kemika no ka manawa lōʻihi, a ua hoʻoponopono i nā pilikia he nui i ka kemika, ka ʻaila, ka lāʻau lapaʻau a me nā ʻano ʻē aʻe o ko mākou ʻāina. Ptfe seals, gaskets, gaskets. Hana ʻia nā sila polytetrafluoroethylene, gaskets, sealing gaskets me ka polytetrafluoroethylene resin molding.

Nā kūlana o ka Polytetrafluoroethylene (PTFE) i ka ʻoihana kemika, petrochemical, hoʻomaʻemaʻe, alkali, acid, phosphate fertilizer, pharmaceutical, pesticide, chemical fiber, dye, coking, coal gas, organic synthesis, non-ferrous smelting, steel, atomic energy and high nā huahana maʻemaʻe (e laʻa, ionic membrane electrolysis), ka lawe ʻana i nā mea viscous a me ka hana, nā meaʻai olakino koʻikoʻi, nā mea inu a me nā mea ʻē aʻe. nā keʻena hana. Medium phosphoric acid, sulfuric acid, nitric acid, hydrochloric acid, nā ʻakika ʻokoʻa like ʻole, nā mea hoʻoheheʻe organik, nā mea hoʻoheheʻe ikaika a me nā mea hoʻolaha kemika corrosive ikaika.

Mahana -100～280 ℃, e ʻae ana i ka hoʻolili koke ʻana a me ka hoʻomehana ʻana, a i ʻole ka hoʻololi ʻana i ka hana wela a me ke anu.

ʻO ke kaomi -0.1 ~ 6.4mpa (ke kaomi ʻino piha i 64kgf/cm2)

-0.1 ~ 6.4mpa (Fullvacuumto64kgf/cm2)

ʻO ke apo paʻa PTFE ka mea nui e hoʻoikaika i ka cylinder, hydraulic system a i ʻole ke kaomi valve me ka ʻole o ka nalowale ʻana o kāna hana sealing, hiki ke pale i ka O-ring "extrusion", hoʻomaikaʻi i kona hoʻohana ʻana i ke kaomi, hiki ke hoʻololi ʻia kona nui e like me nā koi o ka mea kūʻai aku.

ʻO ke apo paʻa PTFE he pale wela kiʻekiʻe - ka wela hana a hiki i 250 ℃.

PTFE apo haʻahaʻa wela kū'ē -- me ka maikai mechanical oughness; ʻOiai ke hāʻule ka mahana i -196 ℃, hiki ke mālama ʻia ka 5% elongation.

ʻO ka PTFE e hoʻopaʻa ana i ke apo corrosion resistance - no ka hapa nui o nā kemika a me nā solvents, e hōʻike ana i ka inert, ka waikawa ikaika a me ka alkali, ka wai a me nā ʻano mea hoʻoheheʻe kūlohelohe.

ʻO ke kani PTFE kūʻē i ka wā - plastik i ke ola ʻelemakule.

PTFE apo lubrication kiʻekiʻe - he mea paʻa i loko o ka friction coefficient.

ʻAʻole pili ke apo PTFE - ʻo ia ka liʻiliʻi liʻiliʻi o ka ʻili i nā mea paʻa a ʻaʻole pili i kekahi mea.
