Polycarbonates (PC) vs Polymer PTFE/FEP Mīkini

ʻO Polycarbonates (PC) he pūʻulu o nā polymers thermoplastic i loaʻa nā pūʻulu carbonate i kā lākou mau hana kemika.ʻO nā polycarbonate i hoʻohana ʻia i ka ʻenekinia he mau mea ikaika, paʻakikī, a ʻike ʻia kekahi mau māka.Maʻalahi lākou e hana, hoʻoheheʻe ʻia, a thermoformed.Ma muli o kēia mau waiwai, loaʻa nā polycarbonates i nā noi he nui.ʻAʻole i loaʻa i nā polycarbonates kahi code identification resin (RIC) a ua ʻike ʻia ʻo ia ʻo "Other", 7 ma ka papa inoa RIC.Hiki ke loaʻa i nā huahana mai ka polycarbonate ka monomer bisphenol A (BPA).

PTFEhe paʻa fluorocarbon, no ka mea, he pūhui kiʻekiʻe-molekala-kaumaha i loko o ke kalapona a me ka fluorine.He hydrophobic ka PTFE: ʻaʻole wai ka wai a ʻaʻole wai ka wai i ka PTFE, ʻoiai e hōʻike ana nā fluorocarbons i nā ikaika hoʻopuehu London ma muli o ke kiʻekiʻe electronegativity o ka fluorine.ʻO ka PTFE kekahi o nā coefficient haʻahaʻa loa o ka friction o kekahi paʻa.

Noi Mea

Polycarbonate (PC) ka hāʻawi ʻana i ka ʻai (nā uhi a me nā hale); Nā mea hoʻohui; Nā sila a me nā ʻōpala; Nā ʻāpana mīkini hana ʻai meaʻai; Nā mea hana hale uila; Nā huila a me nā wili; Nā pahu pahu.

Polymer PTFE/FEP: Nā hoʻonā ʻana o ka hoʻopiʻi ʻana; ʻAʻohe lubricated bearings; O-rings; Sila; Capacitors; Semiconductor manufacturing; Nā ʻāpana uila wela kiʻekiʻe; Gaskets; Nā ʻāpana valve.

Mea Pono

Polycarbonate (PC): Hiki ke hana maʻalahi ʻia; ʻO ke kolo maikaʻi loa; Loaʻa nā māka piha piha i ke aniani; Ka ikaika hopena kiʻekiʻe; Loaʻa nā māka hoʻokō FDA; Loaʻa nā māka i hoʻonui ʻia a me ka ʻaʻahu.

Polymer PTFE/FEP: ʻO nā waiwai dielectric maikaʻi loa; ʻO ka inertness 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.
