Nhau - Chii chinonzi PTFE

Polytetrafluoroethylene (PTFE), inova mhando yemakemikari akawanda, ine kugadzikana kwakanaka kwemakemikari uye inodzivirira ngura. Ndiyo imwe yezvinhu zvakanakisisa zvinodzivirira ngura pasi rose nhasi. Kunze kwe sodium yakanyungudutswa nefluorine yemvura, inogona kutsungirira mamwe makemikari ese. Haizoshanduki mushure mekufashaira mu aqua regia. Inopararira zvakanyanya muzvinhu zvakasiyana-siyana zvinoda kurwisana ne acid, alkali uye organic solvents), Kuvhara, lubrication yakawanda uye isinganamatire, insulation yemagetsi uye kutsungirira kwakanaka kwekudzivirira kukwegura, inodzivirira kupisa kwakanyanya (inogona kushanda patembiricha ye +250℃ kusvika -180℃ kwenguva yakareba). Iye zvino ngatitarisei zvakanaka hunhu hwakasiyana hwechinhu ichi uye mashandisirwo acho.

Hosipa yePTFEinoumbwa nekumanikidzwa kana kugadzirwa kweextrusion; inogonawo kugadzirwa kuita mvura inopararira kuti ifukidzwe, kunyikwa kana kugadzira mafiber. Polytetrafluoroethylene inoshandiswa zvakanyanya mumaindasitiri akadai sesimba renyukireya, dziviriro yenyika, aerospace, electronics, magetsi, makemikari, michina, zvishandiso, mita, kuvaka, machira, kurapwa kwesimbi pamusoro, mishonga, kurapwa kwemishonga, machira, chikafu, simbi uye kunyungudutsa, nezvimwewo, zvinhu zvinodzivirira ngura, zvinhu zvinodzivirira kupisa, machira anodzivirira kunamira, nezvimwewo, zvichiita kuti ive chigadzirwa chisingatsiviwe. PTFE ine hunhu hwakanaka hwakakwana, kuramba kupisa kwakanyanya, kuramba ngura, kusanamatira, kuzvizora, hunhu hwakanaka hwe dielectric, uye coefficient yakaderera yekukweshana. Inoshandiswa semapurasitiki einjiniya, inogona kugadzirwa kuita machubhu ePTFE, tsvimbo, mabhandi, maplate, mafirimu, nezvimwewo. Inowanzo shandiswa mumapaipi anodzivirira ngura, magaba, mapombi, mavharuvhu, radar, michina yekukurukurirana ine frequency yakakwira, uye michina yeredhiyo ine zvinodiwa zvepamusoro. Nekuwedzera chero filler inogona kutsungirira tembiricha inotonhora yePTFE, hunhu hwayo hwemakanika hunogona kuvandudzwa zvakanyanya. Panguva imwe chete, zvimwe zvinhu zvakanaka zvePTFE zvinochengetwa. Mhando dzakazadzwa dzinosanganisira girazi fiber, simbi, metal oxide, graphite, molybdenum disulfide, carbon fiber, polyimide, EKONOL... nezvimwewo. Kuramba kupfeka uye muganho wePV kukosha kunogona kuwedzerwa ka1000.

IyoHosipa yePTFEYakagadzirwa ne suspension polymerized polytetrafluoroethylene resin kuburikidza ne plunger extrusion processing. Pakati pemapurasitiki anozivikanwa, PTFE ine makemikari akasimba uye dielectric properties. PTFE braided packing chinhu chakanaka chinosimbisa simba. Yakarukwa kubva pa PTFE tape yakawedzerwa. Ine hunyanzvi hwakanaka hwakadai se low friction coefficient, wear resistance, chemical corrosion resistance, good sealing, non-hydrolysis, uye non-hardening. Inoshandiswa pa gasket seals nezvinhu zvekuzora zvinoshanda mu media dzakasiyana, pamwe ne electrical insulators dzinoshandiswa pasi pe frequency dzakasiyana. Capacitor dielectric, cable insulation, electrical instrument insulation, etc. PTFE film yakakodzera kuputira capacitor dielectrics, special cables, wire insulation, electrical and instrument insulation and sealing gaskets. Inogona zvakare kushandiswa se non-stick tape, sealing tape, uye demoulding

Zvinhu zvakawanda

Matavi akasiyana-siyana, machubhu, mafirimu epepa, mabhandi, tambo, kurongedza, magasket, uye graphite, molybdenum disulfide, aluminium oxide, girazi fiber, uye carbon fiber zvinoshandiswa sezvizadziro zvekuvandudza hunhu hwePTFE yakachena.
