Qhov txawv
1. Cov khoom sib txawv
PP yeeb nkab yog ua los ntawm polypropylene. PE raw khoom yog polyethylene. PVC raw khoom rau polyvinyl chloride.
2. Qhov sib txawv ntawm kev khoov
PP raj yuav tsum tsis txhob khoov thaum siv. PVC tsis tuaj yeem kho tau, PPR tuaj yeem kho tau 20 npaug ntawm txoj kab uas hla.
PE raj tuaj yeem khoov 180 degrees. PE yeeb nkab muaj nws qhov yooj, nws tuaj yeem khoov thiab tom qab ntawd ncaj rau kev siv. Thaum lub sij hawm tsim khoom, nws tuaj yeem khoov thiab dov mus rau ntau pua meters ntawm cov yeeb nkab coil. Qhov no yog ib qho xwm txheej dabtsi.
3. Kev siv sib txawv
PP yeeb nkab lub hom phiaj kev xa dej siab, thiab kev xa dej haus.
PE feem ntau loj txoj kab uas hla, siv rau cov kav dej txias, vim tias tsis muaj polarity, yog li nws muaj qhov tsis muaj dielectric poob, siab dielectric zog ntawm kev ua tau zoo hluav taws xob, tuaj yeem ua cov khoom siv hluav taws xob ntau zaus, corona resistant yas, thiab muaj peev xwm ua tau siab voltage. cov khoom siv rwb thaiv tsev.
Kev ceev faj rau kev yuav khoom pp khoom yog raws li hauv qab no
Thaum yuav cov khoom siv pp, peb yuav tsum nkag siab cov ntaub ntawv raw ntawm cov khoom. Muaj ntau lub tuam txhab tsim khoom hauv kev tsim cov khoom siv pp, feem ntau siv cov khoom siv pp ntshiab rau kev tsim khoom, tab sis kuj qee cov khoom siv pp tsis tsim los siv cov khoom siv pp ntshiab, vim qee cov tuam txhab lag luam thiaj li txuag tau cov nqi tsim khoom, yuav ntxiv qee cov khoom siv hauv pp. ntau lawm. Raws li ib txwm muaj, tsis muaj kev phom sij rau tib neeg kev noj qab haus huv, thiab nws yog nyob rau hauv cov khoom noj khoom haus qib pp khoom yog qhov zoo tshaj plaws.
Thaum yuav cov khoom siv pp, nco ntsoov xyuas qhov zoo ntawm cov khoom kom ntxaws. Feem ntau, cov tsos ntawm cov khoom zoo pp khoom feem ntau yog pob tshab lossis translucent, thiab feem ntau yuav ci dua, tab sis kuj zoo nkauj dua, ntxiv rau, yuav tsis muaj qhov tshwm sim burr.
