Inoa: PTFE kaula humuhumu
Maikaʻi ʻia: PTFE
Kaumaha: 200g-1000g
Hōʻike: 400D-2700D
Ka waihoʻoluʻu: Keʻokeʻo, ʻeleʻele, a i hana ʻia
Noi:Hoʻohana maʻamau ia i nā pipelines, nā ipu, nā pamu, nā valves, a me nā ʻōnaehana radar, nā lako kamaʻilio kiʻekiʻe, a me nā mea lekiō me nā koi hana kiʻekiʻe.
Hana huahana:ʻO ka hoʻopaʻa ʻana i ka gasket a me nā mea lubricating e hana ana ma nā ʻano media like ʻole.
1.Chemical kū'ē:
He kiʻekiʻe loa ke kūʻē ʻana o PTFE i ka ʻino kino, e like me ka sulfuric acid concentrated, hydrochloric acid, a me ka waikawa nitric.ʻOiai inā i hoʻolapalapa ʻia i loko o ka wai regia, ʻaʻole i loli kona kaumaha a me kona mau waiwai, a aneane hiki ʻole ke hoʻoheheʻe ʻia i ka hapa nui o nā solvents, hiki ke hoʻoheheʻe iki ʻia i nā peralkanes (ma kahi o 0.1g/100g) ma luna o 300 °C.
2.Weather kū'ē:
ʻAʻole ʻae ʻo PTFE i ka makū, ʻaʻole hiki ke puhi ʻia, a paʻa loa i ka oxygen a me nā kukui ultraviolet, no laila he kūpaʻa maikaʻi loa i ka wā.
3. Mechanical waiwai:
Mālama ʻo PTFE i nā waiwai mechanical maikaʻi loa ma kahi ākea ākea o -196 a 260 ° C. ʻO kekahi o nā hiʻohiʻona o nā polymers perfluorocarbon ʻaʻole ia e lilo i brittle i nā haʻahaʻa haʻahaʻa.ʻO ka mānoanoa o ka PTFE he mea nui, ʻo ia ka 2.14-2.20g/cm3, ʻaʻole hiki ke komo i ka wai, a ʻoi aku ka liʻiliʻi o ka equilibrium wai absorption ma mua o 0.01%.
ʻO ka PTFE e he polymer palupalu maʻamau a nāwaliwali, he liʻiliʻi ka attraction like ma waena o nā macro-molecules, a he liʻiliʻi ka ʻoʻoleʻa, paʻakikī a me ka ikaika, a e hoʻololi ʻia ma lalo o ke koʻikoʻi lōʻihi.
