Koj tab tom sim xaj li qub, tab sis ib tus neeg muag khoom hu lawv PVC thiab lwm tus hu lawv UPVC. Qhov tsis meej pem no ua rau koj txhawj xeeb koj tab tom sib piv cov khoom sib txawv lossis yuav cov khoom tsis raug.
Rau cov pob valve nruj, tsis muaj qhov sib txawv ntawm PVC thiab UPVC. Ob lo lus hais txog tib yamunplasticized polyvinyl chloride khoom, uas muaj zog, corrosion-resistant, thiab zoo tagnrho rau cov tshuab dej.
Qhov no yog ib qho ntawm cov lus nug ntau tshaj plaws uas kuv tau txais, thiab nws tsim kev tsis sib haum xeeb hauv cov khoom siv. Tsis ntev los no kuv tau tham nrog Budi, tus thawj tswj kev yuav khoom los ntawm tus xa khoom loj hauv Indonesia. Nws cov neeg yuav khoom tshiab tau raug daig, xav tias lawv xav tau los tsim ob hom li qub. Kuv tau piav qhia rau nws tias rau qhov tsis sib xws peb tsim ntawm Pntek, thiab rau feem ntau ntawm kev lag luam, cov npe tau siv sib hloov. Kev nkag siab vim li cas yuav ua rau koj muaj kev ntseeg siab hauv koj qhov kev txiav txim siab yuav khoom.
Puas muaj qhov sib txawv ntawm PVC thiab UPVC?
Koj pom ob lub ntsiab lus sib txawv thiab ib txwm xav tias lawv sawv cev rau ob yam khoom sib txawv. Qhov kev ua xyem xyav no tuaj yeem ua rau koj cov haujlwm ua haujlwm qeeb thaum koj sim txheeb xyuas qhov tseeb specifications.
Qhov tseem ceeb, tsis muaj. Hauv cov ntsiab lus ntawm cov kav dej nyuaj thiab cov li qub, PVC thiab UPVC yog tib yam. Lub "U" hauv UPVC sawv cev rau "tsis muaj ntaub qhwv," uas twb muaj tseeb rau tag nrho cov PVC li qub.
Qhov tsis meej pem los ntawm keeb kwm ntawm cov yas. Polyvinyl chloride (PVC) yog cov khoom siv hauv paus. Ua kom nws yooj yim rau cov khoom xws li vaj hoses lossis hluav taws xob xaim hluav taws xob, cov tuam txhab ntxiv cov khoom hu ua plasticizers. Txhawm rau paub qhov txawv ntawm daim ntawv qub, nruj los ntawm cov qauv hloov pauv, lo lus "unplasticized" lossis "UPVC" tshwm sim. Txawm li cas los xij, rau cov ntawv thov xws li cov tshuab dej siab, koj yuav tsis siv cov hloov pauv hloov pauv. Tag nrho cov kav dej PVC nruj, fittings, thiab pob li qub yog, los ntawm lawv qhov xwm txheej, unplasticized. Yog li, thaum qee lub tuam txhab sau npe lawv cov khoom "UPVC" kom paub meej dua, thiab lwm tus tsuas yog siv cov "PVC" ntau dua, lawv tau hais txog tib yam khoom muaj zog, nruj. Ntawm Pntek, peb tsuas yog hu lawvPVC pob li qubvim hais tias nws yog cov feem ntau lub sij hawm, tab sis lawv tag nrho technically UPVC.
Puas yog PVC pob li qub puas zoo?
Koj pom tias PVC yog yas thiab raug nqi tsawg dua hlau. Qhov no ua rau koj nug nws qhov zoo thiab xav tsis thoob yog tias nws ruaj khov txaus rau koj daim ntawv thov loj, mus sij hawm ntev.
Yog lawm, zoo PVC pob li qub yog zoo heev rau lawv lub hom phiaj. Lawv tiv thaiv xeb thiab xeb, hnav, thiab muab kev pab cuam lub neej ntev hauv kev siv dej txias, feem ntau ua haujlwm zoo dua li qub.
Lawv tus nqi tsis yog nyob rau hauv lawv cov nqi qis xwb; nws yog nyob rau hauv lawv cov kev ua tau zoo nyob rau hauv tej ib puag ncig. Hlau li qub, xws li tooj dag los yog hlau, yuav xeb los yog xeb thaum lub sij hawm, tshwj xeeb tshaj yog nyob rau hauv lub tshuab nrog dej kho, dej ntsev, los yog tej yam tshuaj. Qhov kev xeb no tuaj yeem ua rau lub valve tuav, ua rau nws tsis tuaj yeem tig thaum muaj xwm txheej ceev. PVC tsis tuaj yeem xeb. Nws yog chemically inert rau feem ntau dej additives, ntsev, thiab me ntsis acids. Qhov no yog vim li cas Budi cov neeg muas zaub nyob rau hauv ntug dej hiav txwv aquaculture kev lag luam nyob rau hauv Indonesia tsuas yog siv PVC li qub. Cov dej ntsev yuav rhuav tshem cov hlau li qub hauv ob peb xyoos xwb, tab sis peb cov PVC li qub tseem ua haujlwm tau zoo rau ib xyoo caum lossis ntau dua. Rau txhua daim ntawv thov hauv qab 60 ° C (140 ° F), aPVC pob valvetsis yog ib qho kev xaiv "cheaper" xwb; nws feem ntau yog qhov kev xaiv ntau dua thiab siv tau ntev dua vim tias nws yuav tsis txeeb los ntawm corrosion.
Dab tsi yog hom pob valve zoo tshaj?
Koj xav yuav lub "zoo tshaj" valve kom ntseeg tau tias koj lub cev muaj kev ntseeg siab. Tab sis nrog ntau cov ntaub ntawv muaj, xaiv qhov zoo tshaj plaws ib qho xav tias nyuaj thiab pheej hmoo.
Tsis muaj ib qho "zoo tshaj" pob valve rau txhua txoj haujlwm. Qhov zoo tshaj plaws valve yog ib qho uas nws cov khoom thiab cov qauv tsim tau zoo sib xws rau koj lub cev kub, siab, thiab tshuaj lom neeg ib puag ncig.
"Zoo tshaj" yog ib txwm txheeb ze rau daim ntawv thov. Xaiv qhov tsis ncaj ncees lawm zoo li siv lub tsheb kis las los rub pob zeb - nws yog qhov tsis raug rau txoj haujlwm. Lub valve stainless hlau yog qhov zoo heev rau qhov kub thiab txias, tab sis nws yog kim overkill rau lub pas dej ua ke, qhov twg PVC valve zoo dua vim nwschlorine tsis kam. Kuv ib txwm coj kuv cov neeg koom tes los xav txog cov xwm txheej tshwj xeeb ntawm lawv qhov project. PVC valve yog qhov sib tw rau cov dej txias vim nws qhov kev tiv thaiv corrosion thiab nqi. Rau cov dej kub, koj yuav tsum tau nce musCPVC. Rau cov pa roj los yog roj, tooj dag yog ib qho kev xaiv, txhim khu kev qha. Rau cov ntawv thov zaub mov lossis tshuaj corrosive heev, stainless hlau feem ntau xav tau. Qhov kev xaiv "zoo tshaj plaws" yog qhov uas yuav tsum tau muaj kev nyab xeeb thiab siv tau ntev rau tus nqi qis tshaj plaws.
Pob Valve Khoom Qhia
| Khoom siv | Zoo tshaj rau | Kub txwv | Qhov tseem ceeb tshaj |
|---|---|---|---|
| PVC | Dej txias, pas dej ua ke, Irrigation, Aquariums | 60 ° C (140 ° F) | Yuav tsis corrode, pheej yig. |
| CPVC | Kub thiab dej txias, me me Industrial | 90 ° C (200 ° F) | Kev kub siab dua li PVC. |
| tooj dag | Cov kav dej, Gas, Siab Siab | 120 ° C (250 ° F) | Durable, zoo rau high-pressure seals. |
| Stainless hlau | Khoom noj khoom haus qib, tshuaj lom neeg, kub / siab | 200 ° C (400 ° F) | Superior zog thiab tshuaj tiv thaiv. |
Dab tsi yog qhov txawv ntawm PVC U thiab UPVC?
Tsuas yog thaum koj xav tias koj nkag siab PVC vs. UPVC, koj pom "PVC-U" ntawm daim ntawv qhia. Lo lus tshiab no ntxiv lwm txheej ntawm kev tsis meej pem, ua rau koj thib ob-xav koj qhov kev nkag siab.
Tsis muaj qhov sib txawv kiag li. PVC-U tsuas yog lwm txoj hauv kev sau ntawv uPVC. Lub "-U" kuj sawv cev rau unplasticized. Nws yog ib lub rooj sib tham naming feem ntau pom nyob rau hauv European lossis thoob ntiaj teb cov qauv (xws li DIN lossis ISO).
Xav txog nws zoo li hais tias "100 las" piv rau "100 bucks." Lawv yog cov ntsiab lus sib txawv rau tib yam nkaus. Nyob rau hauv lub ntiaj teb no ntawm plastics, cov cheeb tsam sib txawv tsim me ntsis txawv txoj kev los sau cov khoom no. Nyob rau hauv North America, "PVC" yog cov lus siv rau cov yeeb nkab tsis sib haum, thiab "UPVC" qee zaum siv rau qhov pom tseeb. Hauv cov teb chaws Europe thiab raws li cov qauv thoob ntiaj teb, "PVC-U" yog lub ntsiab lus engineering ntau dua los qhia tias "tsis muaj ntaub qhwv." Rau tus neeg yuav khoom zoo li Budi, qhov no yog ib qho tseem ceeb ntawm cov ntaub ntawv rau nws pab neeg. Thaum lawv pom European kev sib tw uas qhia txog PVC-U li qub, lawv paub nrog kev ntseeg siab tias peb cov qauv PVC li qub tau raws li qhov xav tau zoo kawg nkaus. Nws tag nrho los rau tib yam khoom: ib qho nruj, muaj zog, tsis muaj yas yas polymer uas zoo meej rau pob li qub. Tsis txhob ntes tau hauv cov ntawv; tsom rau cov khoom siv thiab cov qauv kev ua haujlwm.
Xaus
PVC, UPVC, thiab PVC-U txhua tus xa mus rau tib yam nruj, cov khoom siv tsis zoo rau cov dej txias pob li qub. Cov npe sib txawv tsuas yog cov rooj sib tham hauv cheeb tsam lossis keeb kwm.
