Lub chemistry ntawm pvc vs cpvc
Ob cov ntaub ntawv yog txiv neej-ua thermoplastics muaj ntawm hydrogen, carbon, thiab chlorine. Cov khoom siv hauv paus rau ob qho tib si yog PVC (polyvinyl chloride), tab sis CPVC yog coj los ntawm cov txheej txheem chlorination uas ua rau nws ua kom nruj dua thiab muaj kev chim siab ntau dua.
Cov tshuaj ntsuab ntxiv hauv CPVC (chlorinated polyvinyl chloride) cov txiaj ntsig hauv cov khoom siv yooj yim dua nrog cov khoom siv insulating. Qhov no tso cai rau kev nthuav tawm siv hauv cov dej muaj peev txheej muaj roj av, tiv thaiv hluav taws thiab tseem muaj kev lag luam kev lag luam.
PVC VS CPVVCT DICINGS
Cov kev ntsuas siab rau PVC VS CPVC hloov pauv nrog qhov kub thiab txias. Piv txwv li, ¾ \ PVC yeeb nkab yog nyob ntawm ib qho kev kub siab ntawm 480 PSI ntawm 73 degrees, tab sis nws tsis muaj kev ntsuas kub siab rau dab tsi.
Tib lub loj loj cov yeeb nkab hauv CPVC muaj qhov ntsuas zoo sib xws ntawm 73 degrees, tab sis kuj yog tseem nyob ntawm qhov kub siab {}} psi thiab 180 degrees. Qhov kev ntsuas kub thib ob no rau CPVC yog dab tsi tso cai rau cov khoom siv los siv rau ob daim ntawv thov txias thiab dej kub.
PVC DAIM PVC
PVC tau siv dav siv rau xyoo lawm ua lwm txoj kev xaiv tooj rau tooj thiab pov cov hlau rau DWV (ntws, khib nyiab, thiab qhib) piping. Nws yog dav siv nyob rau hauv lub tsev nyob thiab lub teeb lag luam ua lag luam thiab ib cheeb tsam loj los ntawm 1 ½ ", 2", 3 "rau 6".
Rau daim ntawv thov no, muaj ntau yam ntawm kev teeb tsa haum uas tso cai rau ib qho kev khiav dej khov ntawm cov nqus dej ua kom lub puab tsaig. Ob lub yeeb nkab thiab cov fittings yog dawb hauv cov xim, thiab ob tus yog koom ua ke los ntawm cov txheej txheem hu ua kuab tshuaj vuam.
Hnyav Vuam
Kaus welded pob qij txha yog airtight thiab watertight, ua rau cov khoom zoo tshaj plaws rau kev ua kua dej nres. Qhov ob-theem kev koom tes yog yooj yim thiab yooj yim thov. Nws cuam tshuam nrog lub tshuab nqus tsev ntxhua khaub ncaws lossis muaj feem ntau ua los ntawm acetone, thiab cement uas tau thov rau cov yeeb nkab thiab haum. Qhov sib koom tes "teeb tsa" nyob rau hauv li 20 feeb thiab tsis tuaj yeem sib nrug.
Feem Kev Siv Ntawm Pvc Pvc Pvc
PVC kuj muaj cov khoom siv hluav taws xob siab xws li cov cua sov, cov rhaub thiab ntim cua sov lub zog. Vim hais tias qhov ntsuas kub ntawm cov roj flue yog tsawg dua 130 degrees) thiab cov khoom siv tsis muaj kev nyab xeeb thiab pheej yig los ua roj fluensation. PVC muaj ntau lwm cov siv, tab sis lawv feem ntau tshwj tseg rau cov ntawv thov dej txias.
CPVC txhais tau CPVC
Ua ntej kev qhia ntawm Pex (hla kev sib txuas Polyethylene) Tubing, CPVC yog cov khoom lag luam ntau dua hauv kev ua lag luam rau potable dej piping. Nws tau txais kev pab raws li cov khoom siv tsawg tsawg rau cov khoom siv hauv zog cov khoom xws li tooj liab thiab galvanized steel.
Cov yeeb nkab thiab fittings yog cov xim milky thiab cov yeeb nkab feem ntau muaj ib txoj hlua daj. Txoj kev koom nrog zoo ib yam li ntawm PVC, nrog me ntsis sib txawv txoj cai. Cov yeeb nkab tsis tshua muaj "hws" txij li nws ua raws li insulator. Qhov no kuj ua rau nws xaiv tau zoo rau ob lub tshuab kub thiab txias.
Tsis tas li ntawd, cov khoom txhim kho ntawm cov khoom uas cia rau lub tshuab dej thinner, uas txhim kho kom muaj ntws tawm hauv cov liab thiab PEX tubing hauv nroog loj txog 2 ".
Ntau hom yeeb nkab hangers thiab cov yeeb nkab rwb thaiv tsev tuaj yeem siv rau txhua hom yeeb nkab. Qee hom kws kho tshuab fittings, zoo li compression los yog laub txuas, tuaj yeem siv interchangeages los koom nrog tooj liab, PeX thiab CPVC rau ib leeg hauv kev kho cov xwm txheej.
