PVC rau yeeb nkab fittings
PVC (polyvinyl chloride) yog vinyl polymer.Raws li txoj cai, me ntsis txwv cov tshuaj chlorine los ntawm kev ua haujlwm nrog hydrogen.Nws ua li ntawd los tsim hydrochloric acid (HCl).Cov tshuaj no yog acidic thiab tuaj yeem ua rau corrosion.Yog li txawm tias nws muaj ntau yam khoom tsim nyog, PVC yog corrosive.Qhov no ua rau qee qhov kev sib tw hauv nws txoj kev ua haujlwm thiab kev siv.PVC muaj kev tiv thaiv zoo heev rau cov dej thiab dej txhua hnub.Nws yog soluble hauv tetrahydrofuran, cyclohexane, thiab cyclopentanone.Yog li thaum siv PVC fittings xav txog hom kua dej uas ntws mus.
Yuav kom ua tau raws li cov kev xav tau sib txawv, cov kav dej yuav tsum khoov rau hauv ntau txoj kev thiab lub kaum ntse ntse.Qhov no tuaj yeem hloov pauv tag nrho cov ntws los yog ib feem ntawm qhov ntws.Cov yeeb nkab fittings tau siv los txuas cov kav dej ntawm qhov sib txawv.Lawv tuaj yeem txuas 2 mus rau 4 cov kav dej ua ke.Cov yeeb nkab thiab lawv cov fittings tau siv ntau txoj hauv kev.Piv txwv yog cov dej phwj tuaj, dej, thiab kev siv dej.Kev taw qhia txog cov kav dej PVC yog qhov hloov pauv tseem ceeb hauv tsev thiab kev lag luam.Niaj hnub no ntau lub tsev thiab kev lag luam tab tom hloov los ntawm cov kav hlau mus rau PVC kav.Cov kav dej PVC kav ntev dua.Lawv tsis xeb thiab tuaj yeem tiv taus cov dej ntws.Ua tsaug rau cov txheej txheem loj loj xws li kev txhaj tshuaj molding, lawv pheej yig dua.Hauv qab no yog qee qhov piv txwv ntawm kev txhaj tshuaj molded yeeb nkab fittings.
Yuav ua li cas PVC yeeb fittings yog txhaj molded
PVC fittings yog tsim los ntawm high-pressure txhaj molding.Txoj kev txhaj tshuaj molding pib nrog PVC hauv daim ntawv granules lossis pellets.Nyob rau hauv sib piv rau kev nruam extrusion, molding yog ib tug repetitive cyclic txheej txheem, qhov twg ib tug "steev" ntawm cov khoom yog xa mus rau ib tug pwm nyob rau hauv txhua lub voj voog.
PVC cov ntaub ntawv, granular compound daim ntawv, yog nqus los ntawm ib tug hopper nyob saum lub txhaj tshuaj, mus rau hauv lub chim vaj tse ib tug reciprocating ntsia hlau.Lub thoob yog them nrog qhov yuav tsum tau ntawm cov yas los ntawm cov ntsia hlau tig thiab xa cov khoom mus rau pem hauv ntej ntawm lub thoob.Txoj hauj lwm ntawm cov ntsia hlau yog teem rau ib tug predetermined "shot loj".Thaum lub sij hawm qhov kev txiav txim, lub siab thiab kub "plasticise" cov khoom, uas tam sim no nyob rau hauv nws melted lub xeev, tos kev txhaj tshuaj rau hauv pwm.
Tag nrho cov no tshwm sim thaum lub caij txias ntawm qhov kev txhaj tshuaj yav dhau los.Tom qab lub sij hawm preset lub pwm yuav qhib thiab lub tiav molded haum yuav ejected ntawm lub pwm.
Cov pwm tom qab ntawd kaw thiab cov yas yaj nyob rau hauv pem hauv ntej ntawm lub thoob yog txhaj rau hauv lub siab siab los ntawm cov ntsia hlau tam sim no ua lub plunger.Cov yas nkag mus rau hauv pwm los ua kom haum tom ntej.
Tom qab txhaj tshuaj, rov pib dua thaum lub molded haum mus los ntawm nws lub voj voog txias.
Hais txog PVC txhaj Moulding
Muab cov khoom ntawm PVC qee yam tseem ceeb hauv lawv cov kev txhaj tshuaj molding.Kev txhaj tshuaj molding ntawm PVC xav kom nws raug kub hnyiab.Muab cov khoom siv tshuaj lom neeg thiab lub cev ntawm PVC, qhov no yuav ua rau muaj kev nyuaj siab rau txoj haujlwm.Hauv qab no yog qee qhov kev xav hauv kev txhaj tshuaj molding ntawm PVC yeeb nkab fittings.
Pwm Khoom
Qhov kev xaiv zoo tshaj plaws rau pwm fabrication rau PVC yog anti-corrosion stainless hlau.Qhov no yuav tsum tau zoo polished hardened steel.Muaj lub peev xwm siab tshaj plaws rau kev tso tawm HCl thaum lub sij hawm tsim cov PVC yeeb nkab fittings.Qhov no yog qhov ntau dua nrog PVC hauv lub xeev molten.Tej chlorine nyob rau hauv daim ntawv gaseous yog yuav condense thaum ntaus cov pwm.Qhov no exposes pwm rau corrosion.Txawm hais tias nws yuav tshwm sim, kev siv cov hlau zoo yuav txo tau qhov tshwm sim.Qhov no txuas ntxiv lub neej muaj txiaj ntsig ntawm pwm.Yog li tsis txhob pheej yig thaum nws los txog rau xaiv cov khoom pwm.Rau PVC yeeb nkab txhaj molding, mus rau qhov zoo tshaj plaws hlau koj tuaj yeem tau txais.
Pwm Tsim rau PVC yeeb nkab fittings
Kev tsim cov pwm rau cov khoom sib txawv yog qhov nyuaj.Tsim ib lub pwm rau PVC yeeb nkab fittings yuav siv sij hawm complexity li ib tug notch.Cov kab noj hniav pwm tsis yog ib qho yooj yim txiav tawm ntawm cov khoom zoo thiab cov rooj vag.Cov pwm yog ib qho nyuaj sib dhos.Nws xav tau tus kws tshaj lij hauv kev tsim pwm thiab tsim pwm.Saib qhov zoo ntawm cov yeeb nkab haum.Piv txwv li lub luj tshib yeeb nkab haum.Cov pwm sib dhos tau tsim nyob rau hauv xws li ib txoj kev uas tso cai rau lub filling ntawm cov yeeb nkab lub cev.Tab sis qhov no tshwm sim tsis tau sau lub hollow cheeb tsam.Qhov no tau ua tiav nrog kev txiav txim siab rau cov khoom ejection thiab tso tawm.Cov qauv tsim yuav tsum muaj ntau yam pwm.Qhov no tuaj yeem ua tau txog li 4 feem pwm.Qhov no tsis zoo li cov khoom siv yooj yim uas tuaj yeem ua nrog ob feem pwm.Yog li rau PVC yeeb nkab fittings nrhiav pwm engineers nrog kev paub nrog hom pwm no.Hauv qab no yog ib qho piv txwv ntawm PVC yeeb nkab haum pwm.
