He aha ka Polytetrafluoroethylene Micro Powder?
ʻO ka Polytetrafluoroethylene Micro Powder, ka mea i ʻike ʻia he polytetrafluoroethylene micro paona haʻahaʻa, polytetrafluoroethylene ultrafine pauka, a me ka polytetrafluoroethylene wax, he resin pauka keʻokeʻo i loaʻa ma ka polymerization o ka tetrafluoroethylene i loko o kahi wai i hoʻopuehu ʻia, a ukali ʻia e ka condensation, ka holoi ʻana, a me ka hoʻomaloʻo ʻana e hana i kahi mole haʻahaʻa. paona kahe manuahi.
Introduction
ʻO ka polytetrafluoroethylene micropowder, ka mea i ʻike ʻia he polytetrafluoroethylene micro paona haʻahaʻa a i ʻole polytetrafluoroethylene ultrafine pauka a i ʻole polytetrafluoroethylene wax, he resin pauka keʻokeʻo i loaʻa ma ka polymerization o ka tetrafluoroethylene i loko o kahi wai i hoʻopuehu ʻia, a ukali ʻia e ka condensation, holoi a maloʻo. Loaʻa iā ia nā waiwai maikaʻi loa e like me ke kūpaʻa wela, ka pale ʻana i ka wā, ke kū anuanu, ka haʻahaʻa haʻahaʻa, ka paʻa ʻole, ke kūpaʻa kemika, a me ka insulation uila. Eia kekahi, ma muli o kona liʻiliʻi awelika nui o ka ʻāpana, hiki ke hoʻopuehu maikaʻi a maʻalahi ke hoʻohui like me nā mea ʻē aʻe. Polytetrafluoroethylene (PTFE) ʻO ka pauka ultrafine micro he keʻokeʻo haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa ka pauka e kahe ana me ka paʻa molekala paʻa i loko o -(-CF2-CF2-) n, nona ke kūpaʻa kemika maikaʻi loa, ke kūpaʻa wela, ke kūpaʻa kiʻekiʻe (ʻoi aku ma mua o ʻumi makahiki), UV ke kū'ē, ke kū'ē wela kiʻekiʻe (ʻoi aku ka mahana o ka noi lōʻihi ma kahi o 260 ° C), ka laulā ākea ākea (-200 a + 260 ° C), nā waiwai non-stick maikaʻi, insulation uila kiʻekiʻe (1017Ωcm), kiʻekiʻe o ka lapalapa ahi, a maikaʻi loa. nā waiwai hoʻoluʻu ponoʻī.
Mau waiwai ʻano
PTFE micro pauka Loaʻa nā huahana i ka maʻemaʻe o 100%, kahi kaumaha mole ma lalo o 10,000, a me ka nui o ka nui o ka 0.5-15μm. ʻAʻole wale lākou e mālama i nā waiwai maikaʻi a pau o ka polytetrafluoroethylene akā loaʻa pū kekahi mau waiwai kūʻokoʻa, e like me ka ʻaʻohe hoʻohuihui ponoʻī, ʻaʻohe hopena uila static, solubility maikaʻi, haʻahaʻa molecular kaumaha, maikaʻi dispersibility, kiʻekiʻe self-lubrication, a me ka hōʻemi nui o ka friction coefficient. .
Nā noi o ka Polytetrafluoroethylene Micro Powder
Hiki ke hoʻohana ʻia ka polytetrafluoroethylene micropowder ma ke ʻano he lubricant paʻa wale nō a i ʻole he mea hoʻohui no nā plastics, rubber, coatings, inks, lubricating aila, a me nā momona. Ke hoʻohui ʻia me ka plastics a i ʻole ka lāʻau, hiki ke hoʻohana ʻia nā ʻano hana hoʻoponopono pauka maʻamau e like me ka hui ʻana, a ʻo ka nui o ka hoʻohui ʻana he 5-20%. ʻO ka hoʻohui ʻana i ka polytetrafluoroethylene micro powder i ka ʻaila a me ka momona hiki ke hōʻemi i ka hoʻoemi friction, a hiki i kahi pākēneka wale nō ke hoʻonui i ke ola o ka ʻaila lubricating. Hiki ke hoʻohana ʻia kāna mea hoʻoheheʻe organik e like me ka mea hoʻokuʻu.
