Yuav ua li cas xaiv mica board rwb thaiv tsev khoom rau commutator manufacturing
2022-07-05
Lub commutator mica board, tseem hu ua commutator mica board, yog ib qho tseem ceeb tshaj plaws insulating cov ntaub ntawv nyob rau hauv DC motors. Muaj ob yam ntaub ntawv tseem ceeb rau kev tsim commutator mica board: ib qho yog me me daim ntawv mica, thiab lwm yam yog hmoov mica ntawv. Txhawm rau ua kom cov khoom ncav cuag qhov xav tau tuab, lub phaj mica ua los ntawm cov nplooj ntawv mica yuav tsum tau milled lossis polished. Thaum nias, ob sab yog lined nrog sib txawv liner ntawv thiab canvas, thiaj li hais tias lub thickness yog uniform thiab lub puab nruj nreem tiav tom qab nias. Thaum cov hmoov mica ntawv yog siv los ua cov hmoov mica board, yog tias cov txheej txheem nias zoo, cov txheej txheem milling lossis kev sib tsoo tuaj yeem raug tshem tawm.
Tsis tas li ntawd, raws li qhov sib txawv ntawm cov rwb thaiv tsev ntawm lub cev muaj zog, thiab cov kev xav tau ntawm kev tiv thaiv arc thiab noo noo, shellac, polyester xim, melamine polyacid xim, ammonium phosphate aqueous tov, cyclic resin kua nplaum los yog hloov silicone xim yog siv los ua nplaum rau. tsim ntau hom mica boards.
Kev siv shellac tuaj yeem tsim cov commutator mica daim hlau uas tuaj yeem ncav cuag qhov kub ntawm 100 ° C thiab siab dua, suav nrog commutator cloud plates rau high-speed motors. Tab sis qhov tsis zoo yog tias cov khoom siv tau tsawg.
Nws yog qhov zoo dua li shellac siv polyacid resin condensed los ntawm ortho-jasmonic anhydride thiab glycerin. Nws yog ib qho yooj yim rau tev thiab lo cov nplooj ntawv mica, thiab nws tseem tuaj yeem ua cov txheej txheem ntawm kev txuas cov nplooj ntawv mica, kom cov tswv tsev loj tuaj yeem tsim cov commutator mica boards. . Txawm li cas los xij, qhov tsis zoo yog tias muaj unpolymerized resin nyob rau hauv lub mica board, thiab depolymerization ntawm cov resin nyob rau hauv lub mica board yog intensified nyob rau hauv lub siab kub thiab siab. mus rau saum npoo ntawm lub cev muaj zog commutator.
Thaum siv polyacid resin commutator mica phaj li kub lub cev muaj zog rau insulate lub commutator ntawm traction crane los yog loj lub cev muaj zog, nws yuav tsum tau rhuab ua ntej siv. Tom qab ua li ntawd, thaum nias lub commutator, lub outflow ntawm resin yuav raug txo, uas kuj ua kom muaj kev ntseeg siab ntawm commutator hauv kev ua haujlwm.
Kev siv cov hmoov Anfu raws li cov nplaum tuaj yeem ua rau kev ua haujlwm ntawm commutator mica board tsis hloov raws li cov av noo thiab kub (200 ℃ lossis siab dua). Nws qhov shrinkage tus nqi kuj tseem me dua li lwm cov mica boards, thiab nws qhov kub thiab txias tsis kam tshaj 600 ℃. Yog li ntawd, nws qhov zoo yog feem ntau siab dua li cov lus hais saum toj no ntau yam mica boards, thiab daim ntawv thov ntau kuj dav dua.
Lub mica board ua los ntawm epoxy los yog melamine thiab polyacid resin muaj zoo arc kuj thiab yog siv nyob rau hauv high-ceev DC motors.
Lub mica board ua los ntawm kev hloov kho cov organic resin tuaj yeem tiv taus qhov kub thiab txias thiab siv rau hauv cov motors tshwj xeeb.
NIDE muab ntau yam mica boards thiab commutators, uas yog tsuas yog siv nyob rau hauv lub teb ntawm cov cuab yeej hluav taws xob, brushless motors, tshiab lub zog tsheb motors, khoom siv hauv tsev, nqa cov rooj, cov cuab yeej kho mob txaj thiab lwm yam teb.
