Lub hauv paus rau phau ntawv
Cov khoom siv tsis tau yooj yim polyvinyl chloride (UPVC) tau dhau los ua cov khoom siv pipingone vim nws tau ua ke zoo, durability, thiab tshuaj lom neeg kuj. Ntawm cov khoom muaj ntau yam uas ua GB UPVVC fittings muaj txiaj ntsig, lawv lub peev xwm tiv thaiv kev tawm tsam tshuaj lom yog ib qho tseem ceeb tshaj plaws. Tshuaj lom neeg ua kom ntseeg tau tias cov fittings tuaj yeem tswj hwm kev muaj kev muaj kev lag luam thiab ib puag ncig tsis muaj kev cuam tshuam. Cov xeeb ceem no ua rau UPVVC fittings haum rau cov ntawv thov los ntawm kev faib dej los ntawm kev faib dej thiab khib nyiab mus rau kev thauj khoom thiab kev lag luam. Nkag siab txog cov tshuaj tsis kam ntawm UPVVC fittings muab kev pom muaj txiaj ntsig rau vim li cas lawv ua tau zoo li hauv cov nplaim tshiab.Yog tiasHoobkas 30+}} xyoo tsim kev txhawb nqa xim dawb tus qauv.Qhov no yog peb lub vev xaib.Qhov no yog peb lub vev xaib.www.facebook.com.
Muaj pes tsawg leeg thiab cov qauv ntawm UPVC
UPVVC Differs Los ntawm cov pa hluav taws xob PVC vim tias nws tsis muaj cov yas tshuab, uas yog cov ntxiv siv los ua kom cov plastics ntau hloov tau. Qhov tsis muaj cov yas ua kom nruj thiab txhim kho kev ruaj khov thiab cov qauv kev ruaj ntseg ntawm UPVC, ua rau nws lub zog thiab tiv taus rau kev ua phem. Lub polymer yog tsim feem ntau ntawm cov vinyl chloride monomers, muab nws zoo heev tiv taus corrosion, oxidation, thiab muaj ntau yam tshuaj lom neeg. Cov qauv no kuj pab tiv thaiv kev ua kom muaj kev yuav nqus tau los yog cov tshuaj tiv thaiv nrog cov kua qaub feem ntau, thiab cov ntsev, uas corrode, uas feem ntau corrode lossis demrade hlau fittings.
Mechanism ntawm tshuaj lom neeg
Cov tshuaj tsis kam ntawm UPVVC fittings tshwm sim los ntawm lawv tsis - polymer thiab khov kho polymer caj qaum. Vim tias chlorine atoms nyob rau hauv cov saw hlau polymer tsim ib qho kev tiv thaiv kev tiv thaiv, cov tshuaj reagents tsis tuaj yeem nkag mus lossis ua kom cov qauv molecular. Ib qho ntxiv, UPVC yog hydrophobic, lub ntsiab lus nws tsis yooj yim nqus dej los yog ya raws, tiv thaiv kev cuam tshuam uas muaj pov tseg lwm yam khoom siv. Qhov kev ruaj khov molecular ruaj khov uas cov fittings tswj lawv lub cev thiab cov kws kho tshuab txawm tias raug rau cov tshuaj txhoj puab.
Kuj rau cov acids thiab alkalis
UPVC fittings tshwj xeeb tiv thaiv ntau yam ntawm cov kua qaub thiab alkalis, ua rau lawv zoo tshaj rau kev siv nrog kev siv tshuaj lom neeg. Lawv tuaj yeem ua cov kua qaub muaj zog xws li hydrochloric, sulfuric, thiab nitric acid ntawm nruab nrab ntau yam tsis muaj kev cuam tshuam tseem ceeb. Ib yam li ntawd, alkaline cov kev daws teeb meem zoo li sodium hydrocide thiab potassium hydrocide tsis cuam tshuam rau UPVC raws cov kev ua haujlwm raug. Qhov kev siv tshuaj tsis huv no ua rau cov fittings zoo {}}}}}}} enting tu cov tshuab, kev lag luam acidic thiab tshuaj ntsuab muaj feem ntau tam sim no.
Sib cav nrog cov kuab tshuaj organic
Thaum upvc fittings ua tau zoo tawm tsam ntau cov inorganic tshuaj, lawv txoj kev tawm tsam rau cov kuab tshuaj yeeb zoo nyob ntawm hom ntsuas thiab kub. Feem ntau cov aliphatic hydrocarbons, xws li hexane lossis hephane, muaj me ntsis rau tsis muaj kev cuam tshuam rau UPVC. Txawm li cas los xij, cov ntxhiab hydrocarbons xws li benzene thiab toluene thiab cov kuab tshuaj me me xws li cov tshuaj lom neeg, tuaj yeem ua rau softening lossis o ntawm cov khoom siv sijhawm. Yog li ntawd, thaum UPVC fittings yog siv nyob rau hauv cov ntawv thov muaj feem nrog ntsuas qhov sib xws ntawm txhua yam khoom kom ntseeg tau ntev- lub sij hawm kev ua tau zoo.
Qhov mob kub txog tshuaj lom neeg
Qhov kub thiab txias lub luag haujlwm tseem ceeb hauv kev txiav txim siab cov tshuaj tiv thaiv ntawm upvc fittings. Thaum cov chaw kub siab, tshuaj lom neeg feem ntau yuav ua kom nrawm dua, uas yuav ua rau nrawm dua ntawm cov polymer. UPVC feem ntau ua tau zoo tshaj nyob rau hauv qhov kub thiab txias ntawm 0℃rau 60 degree. Tshaj li qhov kev txwv no, lub sijhawm ntev raug yuav ua rau embrittlement lossis txo qis hauv kev siv zog. Hauv kev ua lag luam tshuaj lom neeg uas kub siab yog qhov tsis muaj chaw nyob, lwm cov ntaub ntawv xws li CPVC (crocornated polyvinyl chloride) tej zaum yuav nyiam vim lawv lub tshav kub kub siab.
Cov ntawv thov hauv cov dej thiab cov tshuab dej khib nyiab
Cov tshuaj tsis kam ntawm UPVVC fittings ua rau lawv zoo tagnrho rau kev siv dej thiab cov khoom tswj dej kom huv. Hauv cov ntawv thov cov dej potable, fittings tiv thaiv chlorine, ozone, thiab lwm yam kev puas tsuaj siv los tswj cov dej zoo. Hauv dej phwj thiab muaj cov dej ntws tawm Lawv txoj kev sab hauv sab hauv kuj tseem tiv thaiv cov nplai txhim kho thiab biofilm tsim, ua kom pom kev zoo thiab txo kev txij nkawm. Raws li qhov tshwm sim, UPVVC fittings feem ntau yog siv nyob rau hauv cov tsheb hauv nroog, dej, thiab cov kav dej tsis sib xws.
Kev Siv Tshuaj Lom thiab Kev Siv Tshuaj
Hauv ib puag ncig kev muaj ib puag ncig, Upvc fittings raug siv dav dav thiab muaj cov tshuaj ua kom haum. Kev lag luam xws li mining, textiles, electroplating, thiab kev ua zaub mov tsis sib haum ntawm upvc piping siv tshuaj kom nyab xeeb thiab muaj txiaj ntsig. Lawv lub peev xwm tiv thaiv kev cuam tshuam los ntawm cov kua qaub thiab cov ntsev uas ua kom pom tseeb tias cov kav dej uas tseem tshuav kev xau nyob ntev thiab cov suab sib txawv. Tsis tas li ntawd, UPVC qhov tsis-}}}}}}}}}}}}}}}}} Qhov xav tau siab, xws li hauv cov chaw tsim khoom.
Kev sib piv nrog lwm cov ntawv luam
Thaum muab piv nrog cov hlau xws li hlau, tooj liab, lossis cov hlau cam khwb cia, upvc fittings kev zoo nyob rau hauv cov nqe lus ntawm cov tshuaj tiv thaiv. Cov kav dej hlau yuav nquag mus rau corrosion, thev naus laus zis, thiab elevelemical cov kev tawm tsam, tshwj xeeb tshaj yog thaum raug rau cov kua qaub lossis dej qab ntsev. Cov teeb meem no tsis tsuas yog txo lub neej xwb tab sis kuj cuam tshuam rau cov kua thauj khoom zoo. Ntawm qhov tod tes, UPVC tsis corrode, xeb, lossis yuav tsum muaj kev tiv thaiv kev tiv thaiv. Piv rau polyethylene (PE) thiab polypropylene (PP), UPVC muab qhov zoo tshaj plaws rigidity thiab seem ruaj khov, uas yog qhov tseem ceeb rau kev sib nqus piping.
Ib puag ncig thiab kev txiav txim siab nyab xeeb
Ntxiv rau lawv cov txiaj ntsig kev ua tau zoo, Upvc fittings pab txhawb rau ib puag ncig kev nyab xeeb los ntawm kev txo cov tshuaj lom thiab cov kev tsis txaus siab. Lawv lub neej ntev kev pabcuam minimizes qhov kev xav tau hloov chaw ntau zaus, txo cov khoom siv pov tseg thiab cov hneev taw. Ntxiv mus, UPVC tsis yog- pakic thiab tsis tso cov khoom muaj kev phom sij thaum lub sijhawm siv kev ua kom zoo, ua kom muaj kev nyab xeeb rau cov dej muajable. Txawm li cas los xij, qhov kawg ntawm nws lub neej, tsim nyog rov ua dua tshiab lossis muab cov khoom siv tsis zoo ntawm cov roj av ib puag ncig yog tias tsis ua kom raug.
Kev kuaj thiab kev ntsuas zoo
Txhawm rau kom ntseeg tau tias cov tshuaj sib haum tsis zoo, UPVC fitting raug ntxias kom nruj thaum tsim khoom. Cov qauv kev ntsuam xyuas ntsuas xyuas lawv txoj kev tawm tsam rau cov tshuaj tshwj xeeb hauv qab tswj qhov kub thiab txias thiab cov xwm txheej siab. Cov no suav nrog kev sim tshuaj ntxuav aphi, tensile zog ntsuas, thiab cuam tshuam kev soj ntsuam. Ua raws li cov qauv thoob ntiaj teb xws li ISO 4422 thiab ASTM D1785 kom ntseeg tau tias fittings raws li cov tshuaj thiab cov neeg siv tshuab ua haujlwm. Cov neeg tsim khoom kuj tau ua ntev-}} hydrostatic siab sim kom paub tseeb tias fittings tuaj yeem tswj hwm cov qauv kev ntseeg tau ntau xyoo dhau los ntawm kev pabcuam.
Txwv thiab cov khoom siv tsim nyog
Txawm tias lawv cov tshuaj tiv thaiv zoo heev, UPVC fittings tsis haum rau txhua daim ntawv thov. Lawv tuaj yeem dhau los ua cov nkig txias hauv qab huab cua txias thiab poob lub zog thaum raug rau qhov kub kom sov rau ncua sijhawm. Lawv kuj tseem tiv taus qee cov tshuaj lom organic thiab cov tshuaj tiv thaiv oxidizing. Rau cov laj thawj no, xaiv cov khoom raug suav nrog kev nkag siab txog cov tshuaj tshwj xeeb, kev ua kom zoo, thiab ib puag ncig cov txheej txheem. Engineers yuav tsum sib npaug yam xws li ntsuas qhov siab, kub ntau, thiab tshuaj lom neeg raug txhim kho kom tau kev ua tau zoo.
