Teflon kub kub hlau yog ua los ntawm polytetrafluoroethylene, feem ntau hu ua fluorine yas, rwb thaiv tsev thiab qhwv hauv cov hlau conductors. Vim tias teflon muaj: tsis - viscosity, kub tsis kam, swb, noo noo tsis kam, hnav tsis kam, corrosion tsis kam thiab lwm yam ntxwv. Txawm li cas los xij, teflon cable kub tsis kam thiab outsourcing khoom muaj qee qhov sib txawv.
Muaj kwv yees li peb hom PTFE hauv qab no: PTFE cov txheej txheem tsis lo tuaj yeem siv tas li ntawm 260 ° C, nrog qhov kub siab tshaj plaws ntawm 290-300 ° C, coefficient sib txhuam qis heev, tiv taus kev hnav zoo thiab ruaj khov tshuaj zoo heev.
FEP: Lub FEP (fluorinated ethylene propylene copolymer) txheej tsis lo yog tsim los ntawm kev yaj thaum lub sijhawm ci, uas muaj kev ruaj khov tshuaj zoo heev thiab cov yam ntxwv tsis lo zoo heev. Qhov kub siab tshaj plaws ntawm kev siv yog 200 ℃.
PFA: Ib yam li FEP, PFA (perfluoroalkyl) cov txheej tsis nplaum raug sib xyaw ua ke los ua cov zaj duab xis porous thaum lub sijhawm ci. PFA muaj qhov zoo ntawm qhov kub siab dua 260 ℃, muaj zog dua, tshwj xeeb tshaj yog rau kev tiv thaiv kev nplaum thiab kev siv tshuaj lom neeg kub.
Teflon kub kub hlau kev ua tau zoo thiab daim ntawv thov.
Cov Khoom: zoo heev corrosion tsis kam, yuav luag insoluble nyob rau hauv ib yam organic solvent, yuav tiv taus roj, muaj zog acid, muaj zog alkali, muaj zog oxidant, thiab lwm yam. High voltage, tsawg zaus poob, tsis muaj dej noo nqus, siab rwb thaiv tsev; Nws muaj zoo heev hluav taws kub, laus tsis kam thiab ntev kev pab cuam lub neej.
Daim Ntawv Thov: hauv kev lag luam hluav taws xob, nws tuaj yeem siv rau cov hlau them nyiaj kub, cov hlau tsis kam kub, cov hlau kub kub, cov hlau tiv taus laus thiab cov hlau tiv taus hluav taws; Hauv kev lag luam khoom siv hauv tsev, nws tuaj yeem siv rau kev txuas hluav taws xob sab hauv ntawm lub tshuab cua txias, lub qhov cub microwave, lub txee tua kab mob hluav taws xob, lub lauj kaub hluav taws xob, lub raj mis thermos hluav taws xob, lub tshuab cua sov hluav taws xob, qhov cub hluav taws xob, lauj kaub kib hluav taws xob, teeb thiab teeb.
