Cov txheej txheem ntawm PTFE yeeb nkab yog: PTFE, extrusion pab → sib tov → nias → ziab → sintering → txias → khoom
Cov txheej txheem molding ntawm PTFE kav muaj xws li thawb txoj kev, extrusion txoj kev, hydraulic txoj kev, vuam txoj kev, winding txoj kev, thiab lwm yam., ntawm cov uas thawb txoj kev yog lub ntsiab txoj kev.Feem ntau, dispersed PTFE resin nrog particle loj ntawm 500μm thiab ib qho pom tseeb ntom ntawm 0.45gml ~ 0.55gml yog siv.Rau cov kav dej me me, siv cov resin nrog cov compression loj, thiab rau cov kav dej loj, siv cov resin nrog me me compression.Cov kev pab nyem feem ntau xaiv 200 thiab 260 cov dej ntxhia.Secondary processing ntawmPTFE tubingtuaj yeem tsim PTFE cua sov-shrinkable tubing, PTFE kauv tubing, PTFE hydraulic tubing, thiab lwm yam.
Polytetrafluoroethylene raj yog ua los ntawm polytetrafluoroethylene dispersed resin nyob rau hauv chav tsev kub siv cov organic hnyav li extrusion pab, thiab ces qhuav thiab sintered.Raws li cov yeeb nkab txoj kab uas hla, nws tuaj yeem muab faib ua ob hom: cov yeeb nkab zoo tib yam thiab cov yeeb nkab micro.Sab hauv txoj kab uas hla ntawm lub raj zoo tib yam yog 4 hli, thiab sab hauv txoj kab uas hla ntawm lub micro raj yog tsawg dua los yog sib npaug li 4 hli.
Cov txheej txheem ntawm PTFE yeeb nkab yog: PTFE, extrusion pab → sib tov → nias → ziab → sintering → txias → khoom.
Polytetrafluoroethylene kav dej muaj zog txhua yam zoo.Cov gaskets yog cov pav ca, V-shaped gaskets, piston rings, pob valve gaskets, thiab lwm yam.PTFE rods, raj, thiab daim hlau los ntawm kev tig los yog txiav, uas yog corrosion resistant, Resistance thiab non-conductivity.
1. Teflon kav feem ntau txais yuav compression molding txoj kev, thiab plunger extrusion molding kuj siv tau.Cov resin tau los ntawm txoj kev dispersion polymerization tuaj yeem tsim los ntawm paste extrusion thiab calendering.
2. PTFE muaj pH tus nqi ntawm 0-14 (tshwj tsis yog rau molten alkali hlau thiab fluorine nyob rau hauv qhov kub thiab txias), uas muaj peev xwm muaj zog txhua yam ntawm 100 ° C thiab 100 ° C.
3. Cov txheej txheem tshwj xeeb yog tias lub siab preforming sib txawv nrog cov duab thiab qhov loj ntawm cov khoom.Tab sis feem ntau nws yog siv.Teflon braided packing yog 8-34.3MPa, thiab cov resin nrog muab tub lim yog 29.4-93MPa.Rau cov ntaub plaub loj nrog lub thickness ntawm txog 600 hli nyob rau hauv cov kev taw qhia nias, tseem muaj lub siab tuav lub sij hawm ntawm 20-30min.Nco ntsoov tias thaum kub qis dua 185 ° C.Teflon tubing yuav nkig.Pure PTFE gasket yog cov khoom ntim huv si uas yuav tsis ua qias tuaj rau hauv kev sib cuag nrog thiab tuaj yeem siv dav hauv zaub mov, tshuaj thiab lwm yam lag luam.
