Xaiv lub qhov dej yas tsis raug yuav ua rau lub kaw lus tsis ua haujlwm vim muaj cua sov lossis tshuaj lom neeg. Lub qhov dej xau tuaj yeem ua rau muaj kev puas tsuaj loj, ua rau qhov project qeeb, thiab ua rau koj lub koob npe nrov nrog cov neeg siv khoom.
Qhov kev xaiv nyob ntawm koj daim ntawv thov.PVC txheemrau cov tshuab dej txias xws li kev ywg dej. XaivCPVCrau cov kav dej kub thiab tiv taus tshuaj zoo dua. Siv PP rau cov tshuaj lom neeg tshwj xeeb thiab cov ntawv thov zaub mov.
Kuv nco qab ib qho kev sib tham nrog Budi txog ib tus neeg siv khoom uas tau muab khoom noj rau lub Hoobkas ua zaub mov tshiab hauv Indonesia. Lawv yuav luag hais tus nqi tag nrho ntawm qhov project nrog tus qauv.PVC li qubkom txuag tau nyiaj. Peb tau tham sai sai txog cov voj voog ntxuav dej kub thiab cov tshuaj tshwj xeeb uas lawv siv. Nws tau pom tseeb tias PVC yuav tsis ua haujlwm hauv ob peb lub hlis. Los ntawm kev piav qhia txog qhov sib txawv ntawmPVC, CPVC thiab PP, peb tau pab lawv xaiv cov khoom siv zoo, tiv thaiv kom tsis txhob muaj teeb meem loj thiab kim heev. Nws yog hom kev paub tshwj xeeb no uas ua rau muaj kev ntseeg siab thiab ua kom tiav qhov project.
Qhov twg zoo dua PVC, UPVC lossis CPVC?
Koj pom PVC, UPVC, thiab CPVC teev nyob rau ntawm daim ntawv qhia txog cov khoom siv. Lawv zoo sib xws, tab sis tus nqi sib txawv. Kev xaiv tsis raug txhais tau tias koj yuav lub valve uas tsis muaj zog lossis kim heev rau txoj haujlwm.
CPVC zoo dua rau cov dej kub thiab muaj kev tiv thaiv tshuaj lom neeg zoo dua. Rau cov kav dej thiab cov li qub, PVC thiab UPVC yog tib yam - cov khoom siv muaj zog, ruaj khov zoo meej rau cov dej txias.
Cia peb piav qhia txog ib qho teeb meem uas ua rau peb tsis meej pem. Thaum peb tham txog cov kav dej thiab cov li qub ntawm Pntek, "PVC" txhais tau tias "UPVC" (Unplasticized Polyvinyl Chloride). Nws yog cov yas ruaj khov, ruaj khov uas koj pom txhua qhov chaw. Yog li, koj tsis tas yuav xaiv ntawm lawv; lawv zoo ib yam rau peb lub hom phiaj. Qhov kev xaiv tiag tiag yog ntawm PVC thiab CPVC. "C" hauv CPVC sawv cev rau Chlorinated. Ib kauj ruam ntxiv hauv cov txheej txheem tsim khoom ntxiv ntau chlorine rau cov qauv ntawm cov khoom. Qhov kev hloov pauv yooj yim no yog qhov ua rau CPVC nws ob qhov zoo tseem ceeb: nws tuaj yeem tswj tau qhov kub siab dua, thiab nws tuaj yeem tiv taus ntau yam tshuaj lom neeg, tshwj xeeb tshaj yog cov kua qaub thiab cov hauv paus. Yog li, yog tias txoj haujlwm tsuas yog siv dej txias xwb, PVC yog qhov kev xaiv pheej yig tshaj plaws. Yog tias muaj cua sov lossis tshuaj lom neeg hnyav, CPVC yog qhov kev xaiv zoo dua, muaj kev nyab xeeb dua.
Lub hom phiaj ntawm CPVC lub pob valve yog dab tsi?
Koj tus neeg siv khoom xav tau lub valve rau cov kav dej kub hauv lub hoobkas lossis tsev. Lub valve PVC dawb ib txwm yuav mos, nkhaus, thiab ua tsis tau zoo, ua rau muaj kev xau dej txaus ntshai thiab lub kaw lus tsis ua haujlwm.
Lub hom phiaj tseem ceeb ntawm lub pob valve CPVC yog kom tswj tau cov kua dej ntawm qhov kub siab dua li tus qauv PVC tuaj yeem tiv taus. Nws yog tsim tshwj xeeb rau kev faib dej kub thiab cov kav dej ua haujlwm hauv kev lag luam uas muaj xeb.
Xav txog CPVC ua qhov ua tau zoo ntawm PVC. Nws txoj haujlwm tseem ceeb yog ua haujlwm qhov twg PVC ua tsis tau. Cov li qub PVC txheem yuav tsum tsis txhob siv rau txhua yam siab dua 60 ° C (140 ° F). Saum toj no qhov kub, cov khoom siv yuav mos thiab poob nws lub peev xwm tuav qhov siab. CPVC, ntawm qhov tod tes, ua haujlwm zoo meej txog li 93 ° C (200 ° F). Qhov no ua rau nws yog cov khoom siv txheem rau cov kav dej kub thiab txias hauv cov tsev nyob thiab cov tsev lag luam. Nws cov tshuaj tiv thaiv zoo dua kuj txhais tau tias nws yog qhov kev xaiv zoo rau cov chaw kho dej, cov chaw ua tshuaj lom neeg, thiab cov ntawv thov kev lag luam qhov twg cov kua dej yuav ua rau PVC hnyav dhau. Koj siv ib qhoCPVC lub qhov dejthaum koj xav tau kev lav phib xaub kev ua tau zoo thiab kev nyab xeeb nyob rau hauv qhov kub thiab kev ntxhov siab tshuaj lom neeg.
Cov pob valve PVC puas tuaj yeem tswj tau qhov siab?
Koj yuav tsum xaiv lub valve rau lub tshuab dej ntws ceev. Koj txhawj tias lub valve yas yuav tsis muaj zog txaus thiab yuav muaj kev pheej hmoo ntawm kev tawg thaum lub zog ua haujlwm ntawm lub tshuab.
Yog,PVC pob valveyog tsim los rau kev kub siab. Lawv qhov ntsuas tseeb, xws li PN10 lossis PN16, qhia tias lawv tuaj yeem tswj tau 10 lossis 16 bar ntawm kev kub, tab sis qhov ntsuas no txo qis thaum qhov kub ntawm dej nce ntxiv.
Qhov no yog ib qho tseem ceeb uas yuav tsum nkag siab txog kev nyab xeeb. Lub pob valve PN16 PVC raug ntsuas kom tuav tau 16 bar (kwv yees li 232 PSI), uas ntau dua li txaus rau feem ntau cov dej siv. Txawm li cas los xij, qhov ntsuas no yog rau dej ntawm chav tsev kub (kwv yees li 20 ° C). Thaum qhov kub ntawm cov kua dej hauv cov yeeb nkab nce siab, cov khoom siv PVC yuav mos dua me ntsis, thiab nws lub peev xwm los tiv taus qhov siab poob qis. Piv txwv li, ntawm 40 ° C, tib lub valve PN16 yuav tsuas yog muaj kev nyab xeeb siv ntawm 10 bar. Ntawm 60 ° C, nws qhov siab tshaj plawskev ntsuas siab poob qistxog li 4 bar. Qhov no yog vim li cas koj yuav tsum tsis txhob siv PVC li qub rau dej kub hauv qab siab. Rau cov tshuab dej siab siab uas Budi cov neeg siv khoom ua haujlwm nrog, uas siv dej txias lossis dej kub ib puag ncig, peb tus qauvPN16 PVC pob valvemuaj zog thiab txhim khu kev qha zoo kawg nkaus.
Vim li cas CPVC kim dua PVC?
Koj tab tom npaj ib daim ntawv hais nqe rau ib tus neeg siv khoom thiab pom tias cov li qub CPVC kim dua li cov PVC. Koj tus neeg siv khoom tab tom nug tias vim li cas lawv thiaj yuav tsum them nyiaj ntxiv rau lub li qub uas zoo ib yam.
CPVC kim dua vim nws dhau los ntawm ib kauj ruam tsim khoom siv zog ntau ntxiv hu uakev siv tshuaj chlorineCov txheej txheem ntxiv no ntxiv tus nqi tab sis ua rau cov khoom siv zoo dua uas tuaj yeem tswj tau qhov kub siab thiab ntau cov tshuaj lom neeg.
Qhov sib txawv ntawm tus nqi yog qhov tshwm sim ncaj qha ntawm cov txheej txheem tsim khoom. Ob qho khoom siv pib ua PVC resin. Yuav kom ua CPVC, peb yuav tsum coj PVC ntawd thiab muab tso rau hauv kev tshuaj lom neeg nyuaj kom yuam kom muaj ntau cov chlorine atoms rau ntawm cov saw polymer. Cov txheej txheem no xav tau cov khoom siv tshwj xeeb, cov khoom siv raw ntxiv (chlorine), thiab lub zog ntau. Koj tsis yog tsuas yog them rau cov xim sib txawv ntawm cov yas; koj them rau qhov kev tsim kho siab heev ntawd. Kuv ib txwm qhia Budi kom piav qhia rau nws cov neeg siv khoom ua kev nqis peev hauv kev nyab xeeb thiab kev ntseeg siab. Tus nqi ntxiv ntawm CPVC valve yog me me piv rau tus nqi ntawm kev puas tsuaj, lub sijhawm tsis ua haujlwm, thiab kev kho uas yuav tshwm sim yog tias lawv siv lub PVC valve pheej yig dua hauv kev siv dej kub uas nws tau lees tias yuav ua tsis tiav. Nws yog ib qho piv txwv ntawm kev them nyiaj ntau dua me ntsis rau cov cuab yeej zoo rau txoj haujlwm.
PVC, CPVC, thiab PP sib piv li cas?
Koj xav tau ib daim ntawv qhia sai sai los piv cov ntaub ntawv no ncaj qha. Kev hloov pauv ntawm cov ntawv sib txawv ua rau koj tsis meej pem thiab nkim sijhawm thaum koj xav tau cov lus teb sai rau tus neeg siv khoom.
Cov lus qhia no muab kev sib piv meej ntawm PVC, CPVC, thiab PP thoob plaws cov lus qhia tseem ceeb. Nws pab koj xaiv cov khoom siv zoo rau koj daim ntawv thov sai sai, xyuas kom koj phim lub valve rau txoj haujlwm.
Yuav kom yooj yim rau Budi thiab nws pab neeg, kuv tau muab daim ntawv qhia no tso ua ke. Nws yog txoj hauv kev ceev tshaj plaws los sib piv cov ntaub ntawv uas peb tau tham thiab qhia txog Polypropylene (PP), lwm txoj kev xaiv tseem ceeb. PP paub txog nws txoj kev tiv thaiv tshuaj lom neeg zoo heev, tshwj xeeb tshaj yog rau cov kuab tshuaj, thiab nws lub zog ruaj khov. Nws yog ib qho kev xaiv zoo rau kev siv hauv kev lag luam thiab qib zaub mov.
