Teflon kub kub hlau yog ua los ntawm polytetrafluoroethylene, feem ntau hu ua fluorine yas, insulated thiab qhwv nyob rau hauv hlau conductors.Vim hais tias teflon muaj: tsis-viscosity, tshav kub tsis kam, zawv zawg, ya raws, hnav tsis kam, corrosion kuj thiab lwm yam ntxwv.Txawm li cas los xij, teflon cable kub tsis kam thiab outsourcing khoom muaj qhov sib txawv.
Muaj kwv yees li ntawm peb hom PTFE hauv qab no: PTFE non-stick coatings tuaj yeem siv tsis tu ncua ntawm 260 ° C, nrog qhov kub siab tshaj plaws ntawm 290-300 ° C, tsis tshua muaj kev sib txhuam coefficient, hnav tsis kam thiab tshuaj lom neeg zoo heev.
FEP: FEP (fluorinated ethylene propylene copolymer) tsis yog-stick txheej yog tsim los ntawm melting txaus thaum lub sij hawm ci, uas muaj cov tshuaj zoo heev stability thiab zoo heev tsis-stick yam ntxwv.Qhov siab tshaj plaws ntawm kev siv yog 200 ℃.
PFA: Zoo li FEP, PFA (perfluoroalkyl) nonstick coatings yog fused los ua cov yeeb yaj kiab ntxeem tau thaum ci.PFA muaj qhov zoo dua qhov kev pabcuam kub kub 260 ℃, muaj zog toughness, tshwj xeeb tshaj yog tsim rau kub tiv thaiv adhesion thiab tshuaj tiv thaiv daim ntaub ntawv.
Teflon siab kub Hlau kev ua tau zoo thiab daim ntawv thov.
Khoom: zoo heev corrosion kuj, yuav luag insoluble nyob rau hauv tej organic hnyav, muaj peev xwm tiv taus roj, muaj zog acid, muaj zog alkali, muaj zog oxidant, thiab lwm yam.High voltage, tsawg zaus poob, tsis muaj noo noo nqus, siab rwb thaiv tsev tsis kam; Nws muaj hluav taws xob zoo heev, aging kuj thiab kev pab lub neej ntev.
Daim ntawv thov: hauv kev lag luam hluav taws xob, nws tuaj yeem siv rau qhov kub thiab txias xaim, tsis tshua muaj kub tsis kam xaim, kub kub cua sov hlau, kev laus tiv thaiv hlau thiab nplaim hluav taws xob hlau; Hauv kev lag luam khoom siv hauv tsev, nws tuaj yeem siv rau hauv kev xaim cua txias. , microwave qhov cub, hluav taws xob tua kab mob, hluav taws xob mov cooker, hluav taws xob thermos lub raj mis, hluav taws xob rhaub, hluav taws xob qhov cub, hluav taws xob kib lauj kaub, teeb thiab teeb.
