PTFE membrane tuaj yeem siv nruab nrab ntawm lub tshuab hluav taws xob winding tooj liab ntawv ci, rwb thaiv tsev thiab nplaum, los ntawm cov yeeb yaj kiab los txhim kho cov chav kawm rwb thaiv tsev ntawm transformer, txo qhov sib txawv ntawm cov khaubncaws sab nraud povtseg ntawm transformer thiab tuaj yeem txhim kho cov neeg kho tshuab lub zog ntawm transformer, ntxiv rau, PTFE membrane tuaj yeem siv rau qhuav hom transformer, capacitor, hluav taws xob ntsuas, xws li gasket ntawm cov khaubncaws sab nraud povtseg ntawm rwb thaiv tsev thiab tshav kub-resistant electromagnet, kab installation, tshav kub rwb thaiv tsev ntawm cov hlau, muaj lub dav dav kev lag luam prospect.
Transformers feem ntau yog siv los muab cov teeb liab tam sim no thiab qhov hluav taws xob rau hluav taws xob ntsuas hluav taws xob, ntsuas, tswj, kev tiv thaiv relay, thiab lwm yam. Lawv qhov tseeb thiab kev ntseeg tau zoo sib xws rau kev nyab xeeb, kev ruaj ntseg thiab kev lag luam ntawm lub zog hluav taws xob, thiab yog ib qho tseem ceeb. high-voltage khoom nyob rau hauv lub hwj chim system.Nrog rau txoj kev loj hlob ntawm kev lag luam fais fab, kev sib kis ntawm lub zog hluav taws xob yog nce, thiab kev khiav hauj lwm voltage ntawm lub zog hluav taws xob network tau nce siab dua.Nrog rau kev txhim kho txuas ntxiv ntawm qib voltage, lub transformer tau ntsib nrog cov teeb meem uas cov txheej txheem rwb thaiv tsev tsis yooj yim kom tau raws li qhov yuav tsum tau ua hauv kev tsim khoom.
Raws li paub rau txhua tus, polytetrafluoroethylene (PTFE) vim tias lawv cov kev ua tau zoo (chav kawm c rwb thaiv tsev), tshuaj tiv thaiv corrosion, huab cua tsis kam, cov khoom siv hluav taws xob thiab thermal stability ntawm qhov txawv tshaj plaw, tshav kub-resistant kev ua tau zoo ntawm ultra dav (siv rau lub sijhawm ntev. ua hauj lwm kub 150 ℃ ~ + 260 ℃), thiab lwm yam., nyob rau hauv lub tshav pob ntawm cov khoom siv hluav taws xob, hlau thiab cable, rwb thaiv tsev tau ntau thiab ntau lug siv.PTFE daim nyias nyiastuaj yeem siv nruab nrab ntawm cov transformer winding tooj liab ntawv ci, rwb thaiv tsev thiab nplaum, los ntawm cov zaj duab xis los txhim kho cov rwb thaiv tsev chav ntawm transformer, txo qhov sib txawv ntawm cov khaubncaws sab nraud povtseg ntawm transformer thiab yuav txhim khu lub zog txhua yam ntawm transformer, ntxiv rau, PTFE membrane yuav siv tau. rau qhuav hom transformer, capacitor, hluav taws xob ntsuas, xws li gasket ntawm cov khaubncaws sab nraud povtseg ntawm rwb thaiv tsev thiab tshav kub-resistant electromagnet, kab installation, rwb thaiv tsev kub ntawm cov hlau, muaj lub dav dav kev lag luam prospect.Txoj kev npaj thiab kev tshawb fawb txog kev ua haujlwm ntawmPTFE zaj duab xisrau kev sib nrig sib inductor rwb thaiv tsev kuj tau them nyiaj ntau heev los ntawm ntau domestic thiab txawv teb chaws kev tshawb fawb cov neeg ua haujlwm thiab kev lag luam.Hauv daim ntawv no, txoj kev npaj ntawm PTFE zaj duab xis tau los ntawm kev tsim khoom tiag tiag thiab kev ua haujlwm yog kawm los ntawm kev sim.
1. Kev npaj ntawm PTFE zaj duab xis
1.1 Xaiv cov resin
Cov polytetrafluoroethylene (ptfe) zaj duab xis resin siv rau kev sib nrig sib inductor rwb thaiv tsev yuav tsum raug tshem tawm resin nrog uniform molecular hnyav tis thiab siab crystallinity, feem ntau nrog crystallinity saum 98 thiab molecular hnyav ntawm 1O ~ 1O.Cov resin particle loj yog hais txog 30t ~ m.PTFE ntawm no specification yog siv los npaj PTFE zaj duab xis rau kev sib nrig sib inductor rwb thaiv tsev nrog zoo heev lub cev thiab cov khoom hluav taws xob zoo heev.
- Kev tsim cov txheej txheem ntawm ptfe zaj duab xis
(1) pretreatment ntawm PTFE raw khoom
PTFE suspended nplua resin tau muab tso rau hauv ib lub tsev cog khoom tas li ntawm 20 ℃ ~ 23 ℃ rau 24 teev rau kev kho ua ntej.
(2) ramming thiab sifting
Lub pre-kho PTFE tshem tawm zoo cob tau pounded thiab sifted los ntawm rammer kom cov resin xoob rau molding.
(3) pwm
Txais cov txheej txheem txias txias, ntxiv 10000gPTFE tshem tawm cov khoom siv zoo rau hauv pwm, nias qhov khoob nrog 20MPpa molding ib lub siab ntawm 100 tuj tsis siv neeg siab tshuab, xyuam xim rau cov pa thaum lub sij hawm nias, thiab zam qhov tawg ntawm qhov khoob.
(4) sintering
Muab cov khoom nias rau hauv qhov kub thiab txias sintering rauv, mus rau 50.C / h tus nqi ntawm kub nce mus rau 330 ℃, rwb thaiv tsev rau 3h, ces ntawm 30 ℃ / h tus nqi ntawm kub nce mus rau 380 ℃, rwb thaiv tsev 1O ~ 14h, thiab tom qab ntawd ntawm 30 ~ 40 ℃ / h tus nqi ntawm qhov kub poob mus rau 320 ℃, rwb thaiv tsev rau 3 ~ 4h, thaum kawg ntawm 50 ℃ / h tus nqi ntawm qhov kub poob mus rau 150 ℃, tua hluav taws xob cua txias rau chav tsev kub, tshem tawm cov khoom.
(5) rotary txiav rau hauv zaj duab xis
Cov sintered preforms yog hloov mus ua nyias zaj duab xis preforms los ntawm tshwj xeeb tshuab dhos.Lub daim nyias nyias yog 0.2mm × 255mm × 300m (thickness × dav × ntev).
(6) calendering orientation
Tom qab kev txiav tawm, qhov kev taw qhia dawb paug yog ua tiav los ntawm cov ntawv qhia kub kub (saib daim duab 2), thiab cov kev taw qhia qib yog 1.8 ~ 2.0.Lub thickness yog 0.1 hli directional zaj duab xis, kub yob kub tswj nyob rau hauv 15O ℃ ~ 180 ℃.
(7) txiav
Cia peb ua lub thickness 0.1mm directional zaj duab xis nrog tshwj xeeb txiav tshuab ua rau hauv 0.Ptfe zaj duab xis rau rwb thaiv tsev ntawm kev sib nrig sib inductor 1mm × 35mmx 450 ~ 500m (thickness × dav × ntev).
(8) kev tshuaj xyuas ntawm kev ntim khoom
Polytetrafluoroethylene (ptfe) zaj duab xis rau rwb thaiv tsev ntawm cov txheej txheem ct yuav tsum tau ua qauv rau kev soj ntsuam kev ua haujlwm sab hauv, thiab kev tshuaj xyuas qhov zoo thiab qhov loj ntawm cov yeeb yaj kiab yuav tsum tau ua tib lub sijhawm.PVC zaj duab xis hnab yuav tsum tau siv rau ntim cov khoom uas dhau qhov kev soj ntsuam, thiab daim ntawv pov thawj tshuaj xyuas yuav tsum tau txuas nrog.
2.2 Performance index ntawm PTFE zaj duab xis
Hauv qhov kev sim no, PTFE zaj duab xis nrog cov kev taw qhia sib txawv (kev taw qhia qib ntawm cov khoom siv, nws tus nqi yog qhov piv ntawm qhov ntev ntawm cov qauv ntawm zaj duab xis ua ntej thiab tom qab cua sov) piv nrog cov qauv ntsuas hauv tensile lub zog, elongation ntawm tawg, dc breakdown voltage siv thiab lwm yam khoom.
