Acrylonitrile butadiene styrene (ABS) vs Polymer PTFE/FEP Mīkini

ʻO Acrylonitrile butadiene styrene (ABS) (kemimi (C8H8)x·​(C4H6)y·​(C3H3N)z) he polymer thermoplastic maʻamau.ʻO kona mahana hoʻololi aniani ma kahi o 105 °C (221 °F).He amorphous ʻo ABS a no laila ʻaʻohe wahi hoʻoheheʻe ʻoiaʻiʻo. ʻO Polytetrafluoroethylene (PTFE) kahi fluoropolymer synthetic o tetrafluoroethylene he nui nā noi.ʻO ka inoa inoa inoa maikaʻi loa o nā kumu hoʻohālikelike PTFE he polymer na Chemours.ʻO Chemours kahi spin-off o DuPont Co., nāna i ʻike i ka pūhui ma 1938.

ʻO nā waiwai mechanical koʻikoʻi o ABS ka hopena a me ka paʻakikī.Hiki ke hoʻololi i nā ʻano hoʻololi e hoʻomaikaʻi i ka pale ʻana i ka hopena, ka paʻakikī, a me ka pale wela.Hiki ke hoʻonui ʻia ke kūpaʻa hopena ma ka hoʻonui ʻana i ka nui o ka polybutadiene e pili ana i ka styrene a me ka acrylonitrile, ʻoiai ke kumu kēia i nā loli i nā waiwai ʻē aʻe.ʻAʻole hāʻule koke ka pale ʻana i ka hopena i nā mahana haʻahaʻa.ʻOi aku ka maikaʻi o ke kūpaʻa ma lalo o ka ukana me nā haʻahaʻa liʻiliʻi.No laila, ma ka hoʻololi ʻana i nā ʻāpana o kāna mau mea, hiki ke hoʻomākaukau ʻia ʻo ABS ma nā papa like ʻole.Hiki i ʻelua mau ʻāpana nui ke ABS no ka extrusion a me ABS no ka hoʻoheheʻe ʻana, a laila kiʻekiʻe a me ke kūpaʻa hopena.ʻO ka maʻamau, loaʻa iā ABS nā hiʻohiʻona pono i loko o kahi pae wela mai −20 a 80 °C (−4 a 176 °F).

ʻO ka PTFE he polymer thermoplastic, he paʻa keʻokeʻo ma ka lumi wela, me ka nui o 2200 kg / m3.Wahi a DuPont, ʻo kona helu heheʻe he 600 K (327 °C; 620 °F).Mālama ʻo ia i ka ikaika kiʻekiʻe, paʻakikī a me ka lubrication ponoʻī ma nā haʻahaʻa haʻahaʻa a hiki i 5 K (−268.15 °C; −450.67 °F), a me ka hoʻololi maikaʻi i nā mahana ma luna o 194 K (−79 °C; −110 °F).Loaʻa ka PTFE i kāna mau waiwai mai ka hopena aggregate o nā kaula kalapona-fluorine, e like me nā fluorocarbons a pau.ʻO nā kemika wale nō i ʻike ʻia e pili ana i kēia mau mea paʻa kalapona-fluorine he mau metala reactive loa e like me nā metala alkali, a ma nā mahana kiʻekiʻe e like me nā metala e like me ka aluminika a me ka magnesium, a me nā mea hana fluorinating e like me xenon difluoride a me cobalt(III) fluoride.

Hoʻohālikelike o Acrylonitrile butadiene styrene (ABS) a me Polymer PTFE/FEP Waiwai Waiwai

Noi Mea

Acrylonitrile butadiene styrene (ABS)ipes a me nā mea hoʻopili; Nā kino valve, nā lako hana lima.

polymer PTFE/FEP: Hoʻopili ʻana i nā kelepona; ʻAʻohe lubricated bearings; O-rings; Sila; Capacitors; Hana semiconductor; Nā ʻāpana uila wela kiʻekiʻe; Gaskets; Nā ʻāpana valve.

ʻO Acrylonitrile butadiene styrene (ABS): Ka ikaika hopena maikaʻi loa; ʻO nā waiwai hana a me ka mīkini hana maikaʻi; Nā waiwai aesthetic maikaʻi loa; ʻO ke kūpaʻa kemika maikaʻi; Nā mīkini me ka maʻalahi; Haʻahaʻa haʻahaʻa haʻahaʻa; ʻO ka ʻino a me ka pale ʻana;

Polymer PTFE/FEP: ʻOi aku ka maikaʻi o nā waiwai dielectric; ʻAʻole i ka hapa nui o nā kemika; ʻO ka wela kiʻekiʻe a me ke kūpaʻa kemika; Haʻahaʻa haʻahaʻa haʻahaʻa o ka friction; ʻOi aku ka maikaʻi o ka pale ʻana i ka radiation; Zero moisture absorption; Pili ʻole i ka mana pinepine; Machinability.
