ʻO Teflon PTFE ka mea i ʻike ʻia he polytetrafluoroethylene.Teflon PFA i ʻike ʻia he soluble polytetrafluoroethylene.Many kiwi kūʻai ʻaʻole maopopo loa i ʻoi aku ka maikaʻi o ka corrosion kū'ē no nā kiwi lele e hoʻohana ana i ka PTFE a me ka PFA? He aha nā pōmaikaʻi a me nā pōʻino o kēlā me kēia? ʻO ka ʻokoʻa o ka pale wela, ʻo wai ka mea ʻoi aku ka maikaʻi?
ʻOkoʻa ke ʻano
1.PFA: he copolymer o kahi liʻiliʻi o ka perfluoropropyl perfluorovinyl ether a me ka polytetrafluoroethylene.2.PTFE: he hui polymer i hana ʻia e ka polymerization o tetrafluoroethylene.
ʻO nā hiʻohiʻona likeʻole
Nā hiʻohiʻona PFA
(1) ʻO nā mea kristal, haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa.
) ʻAʻoleʻo ka mahana o ka wīwī iʻoi aku ka nui o ka pālolo.
(3 Trasucent pelles, ijection molding a extrusion molding. Molding temperature is 350-400C, 475 ℃ a ma luna aʻe he maʻalahi ke kumu i ka ʻulaʻula a i ʻole blistering. E nānā i ka paʻakikī o ka demolding.
(4) Ma muli o ka hopena ʻino o ka mea hoʻoheheʻe ʻia ma luna o ke metala, pono ka hana lōʻihi i ka chrome plating ma nā ʻano mold.PTFE.
ʻO ke ʻano o ka PTFE
(1) Kūlana wela kiʻekiʻe: lōʻihi-hoʻohana wela wela 200~260 ℃;
(2) Ke pale wela haʻahaʻa: ʻoi aku ka palupalu ma -100 ℃;
(3) Ke kū'ē i ka corrosion: kū'ē i ka aqua regia a me nā mea hoʻoheheʻe organik a pau;
(4) Kūleʻa i ka wā: ke ola ʻelemakule maikaʻi loa o nā plastics;
(5) Lubrication kiʻekiʻe: me ka liʻiliʻi liʻiliʻi o ka friction (0.04) ma waena o nā plastics;
(6) Non-sticky: Loaʻa iā ia ka liʻiliʻi liʻiliʻi ma waena o nā mea paʻa me ka ʻole e pili ana i kekahi mea. Summary
ʻO ka ʻokoʻa nui loa, ʻoi aku ka maʻalahi o ka PFA i ka hana a ʻoi aku ka pipiʻi ma mua o ka PTFE, akā i ka hoʻomaʻamaʻa ʻana, ʻoi aku ka maikaʻi o ka PTFE i ka corrosion resistaran a ʻoi aku ka kūʻē i nā wela kiʻekiʻe.
ʻO Senheng Flustic Fling Techictic Technology he mea hana hana a me nā mea kūʻai aku o nā mea kūʻai aku, eʻoluʻolu e hoʻopili iā mākou. + 861506725016404
