ʻO ka hana a me nā noi PTFE

He ahaPTFE?

E hoʻomaka kākou e ʻimi i ke ʻano o ka PTFE.No ka hāʻawi ʻana i kona inoa piha, polytetrafluoroethylene he polymer synthetic i loaʻa i ʻelua mau mea maʻalahi;kalapona a me ka fluorine.Loaʻa ia mai ka tetrafluoroethylene (TFE) a loaʻa iā ia kekahi mau waiwai kūʻokoʻa e lilo ia i mea pono i nā ʻano o nā noi.ʻo kahi laʻana:

Kahi hehee kiʻekiʻe loa: Me kahi helu heheʻe ma kahi o 327°C, he liʻiliʻi loa nā kūlana kahi e pōʻino ai ka PTFE e ka wela.

Hydrophobic: ʻO ke kūpaʻa ʻana i ka wai, ʻaʻole ia e pulu, pono ia i ka kuke ʻana, nā lole ʻeha a me nā mea hou aku.

Kemika inert: ʻAʻole e hōʻino ka hapa nui o nā mea hoʻoheheʻe a me nā kinikona i ka PTFE.

ʻO ke koena haʻahaʻa o ka friction: ʻO ka coefficient o ka friction o PTFE kekahi o ka haʻahaʻa loa o kekahi paʻa i ke ola, ʻo ia hoʻi, ʻaʻohe mea e pili iā ia.

ʻO ka ikaika flexural kiʻekiʻe: ʻO ia ka hiki ke kulou a hoʻopololei, ʻoiai me nā haʻahaʻa haʻahaʻa, ʻo ia ka mea hiki ke hoʻohana maʻalahi i nā ʻano ʻano like ʻole me ka nalowale ʻole o kona kūpaʻa.

Ka hana ana o ka PTFE

Hiki ke loaʻa ka PTFE ma nā ʻano granular, dispersion a me ka pauka maikaʻi.ʻO Semi-crystalline PTFE he kiʻekiʻe ka wela hoʻoheheʻe a me ka viscosity hoʻoheheʻe, hana paʻakikī i ka extrusion maʻamau a me ka hoʻoheheʻe ʻana.No laila, ʻoi aku ka like o ka hoʻoili ʻana o ka PTFE me ka hoʻoili ʻana i ka pauka ma mua o nā plastics kuʻuna.

Hana ʻia ʻo Granular PTFE i kahi hopena polymerisation hoʻokuʻu wai.Hoʻohana pinepine ʻia ka resin granular i loaʻa i ke ʻano ma o ka hoʻoheheʻe ʻana.Hana ʻia nā huahana dispersion PTFE ma ke ʻano like, me nā mea hoʻopuehu hou.Hiki ke hoʻohana ʻia nā huahana dispersion no nā uhi PTFE a i ʻole hiki ke hana ʻia i loko o kahi kiʻi ʻoniʻoni ma o ka hoʻolei ʻana i ke kiʻiʻoniʻoni.Hoʻokumu ʻia ka pauka PTFE i kahi hopena polymerization emulsion.Hiki ke hoʻopili ʻia ka pauka maikaʻi i hoʻopaʻa ʻia i loko o nā lipine PTFE, PTFE tubing, a me ka insulation uea, a i hoʻohana ʻia ma ke ʻano he mea hoʻohui e hoʻonui i ka pale ʻana i nā mea polymeric ʻē aʻe.

ʻO nā noi 5 kiʻekiʻe o PTFE

1. Hoʻohana i nā waiwai anti-corrosion

ʻAʻole kūpono ka Rubber, aniani, metala a me nā mea ʻē aʻe i nā kūlana koʻikoʻi o ka mahana, ke kaomi a me ka ʻenekini media coexistence ma muli o ko lākou mau hemahema i ka pale ʻana i ka corrosion.Eia nō naʻe, ʻoi aku ka maikaʻi o ka PTFE anti-corrosion kūpaʻa a no laila ua lilo ia i mea nui e pale ai i ka corrosion no ka ʻaila, kemika, textile a me nā ʻoihana ʻē aʻe.

2. Hoʻohana i nā waiwai friction haʻahaʻa i ka ukana

ʻAʻole kūpono ka lubrication aila no nā ʻāpana friction o kekahi mau mea hana, no ka mea, hiki ke hoʻoheheʻe ʻia ka lubricating grease e nā solvents a ʻaʻole hana, a i ʻole nā ​​​​huahana i loko o ka lāʻau lapaʻau, meaʻai, textile a me nā ʻoihana ʻoihana ʻē aʻe e pale aku i ka hoʻopaʻa ʻia e nā lubricants.No laila, ʻo ka plastik PTFE, ʻoi aku ka haʻahaʻa o ka coefficient o ka friction ma mua o nā mea paʻa ʻē aʻe i ʻike ʻia, ua lilo ia i mea kūpono loa no ka lubrication ʻaila-ʻole (kaumaha pololei) o nā ʻāpana mīkini.

3. Hoʻohana i ka uila a me ka uila

ʻO ka poho haʻahaʻa a me ka liʻiliʻi dielectric mau o nā mea PTFE e hiki ai iā ia ke hana ʻia i uea enamled no nā mīkini micro, thermocouple a me nā mea hoʻokele.ʻO ke kiʻi ʻoniʻoni PTFE ka mea hoʻokalakupua maikaʻi loa no ka hana ʻana i nā capacitors, radio insulation liner, insulated cables, motors and transformers, a ʻo ia kekahi o nā mea waiwai nui no ka aerospace a me nā mea uila ʻenehana.

4. Hoʻohana i ka lāʻau lapaʻau

Hoʻonui ʻia ka PTFE maʻemaʻe a hiki ke hoʻololi ʻia, no laila ʻaʻole ia e hōʻole ʻia e ke kino, ʻaʻohe hopena physiological i ke kino kanaka, hiki ke hoʻopaʻa ʻia e kekahi ʻano, a he ʻano multi-microporous.

5. Hoʻohana i nā waiwai anti-adhesive

Me ka haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa o nā mea paʻa, ʻaʻole pili ʻo PTFE Teflon i kekahi mea.Eia kekahi, he kūpaʻa maikaʻi loa ia i nā wela kiʻekiʻe a haʻahaʻa.ʻO ka hopena, ua hoʻohana nui ʻia ia i nā hiʻohiʻona anti-adhesive o nā pans non-stick.
