Yuav Ua Li Cas Kub Kub Resistant Yog PVC Yas Yeeb Nkab
Apr 02, 2022
Cov yam ntxwv: PVC-U yas yeeb nkab muaj qhov zoo tshaj plaws khoov kev ua haujlwm, zoo tshuaj corrosion kuj, txhua yam muaj zog, kev laus ua haujlwm thiab kub tsis kam.
Cov kabmob muaj peev xwm: PVC-U yas yeeb nkab tuaj yeem dais qhov hnyav ntawm ko taw yam tsis muaj kev tawg.
Daim ntawv thov teb ntawm PVC-U yas yeeb nkab: lub tes tsho hlau, lub tes tsho zoo nkauj, haum rau kev thauj mus los ntawm cov kua thiab roj, kev tiv thaiv kab hluav taws xob, kev tiv thaiv tsheb tsheb, kev siv tshuab tshuab, cov twj paj nruag tsis siv neeg, thiab lwm yam.
PVC-U yas yeeb nkab yog lub teeb hauv qhov hnyav thiab yooj yim hauv kev tuav thiab thauj khoom. PVC-U yas yeeb nkab yog lub teeb nyob rau hauv cov khoom, nrog rau ib qho kev nqus ntawm tsuas yog 1/5 ntawm cov yeeb nkab hlau. Nws yog qhov yooj yim hauv kev tuav, thauj khoom thiab tshem tawm thiab kev tsim kho, uas tuaj yeem txuag cov nqi tsim kho. PVC-U yas yeeb nkab muaj zoo heev corrosion kuj thiab tshuaj tiv thaiv. PVC-U yas yeeb nkab muaj cov kua qaub zoo heev, alkali tsis kam thiab corrosion kuj. Nws yog qhov tsim nyog rau kev lag luam tshuaj lom neeg, cov dej khib nyiab, cov kav dej huv huv thiab lwm yam. Cov phab ntsa ntawm cov yeeb nkab PVC yog du nrog cov dej tsis tshua muaj zog. Nws qhov roughness coefficient tsuas yog 0.009, uas yog qis dua lwm cov kav dej. Nyob rau hauv cov xwm txheej ntawm tib txoj kab uas hla, ntws yog loj thiab nplai tsis txuas. PVC-U yas yeeb nkab muaj cov neeg kho tshuab siab zog thiab zoo dej siab zog thiab cuam tshuam lub zog. Nyob rau hauv chav tsev kub, PVC-U yas yeeb nkab yog haum rau piping engineering nyob rau hauv ntau yam kev mob.
PVC-U yeeb nkab yog siv los ua cov kav dej. Vim nws tus yam ntxwv, qhov ntsuas kub hauv tsev tsis tu ncua yuav tsum tsis txhob siab tshaj 40 degree, thiab qhov kub ntawm qhov dej tam sim no yuav tsum tsis txhob siab tshaj 80 degree. Qhov no feem ntau tsis quav ntsej. Nyob rau hauv cov txheej txheem ntawm kev siv mus sij hawm ntev, nws yuav ua rau cov dej xau ntawm cov yeeb nkab sib koom ua ke, tshwj xeeb tshaj yog nyob rau hauv qee qhov chaw kuaj biochemical hauv lub tsev sim ntawm cov tsev kawm qib siab thiab cov tsev kawm qib siab. Kev daws tsuas tuaj yeem hloov pauv lwm cov kav dej hlau. Nyob rau tib lub sijhawm, kev teeb tsa ntawm PVC yeeb nkab yuav tsum tsis txhob raug teeb tsa hauv cov khoom siv hluav taws xob, uas yuav tsum tau them nyiaj tshwj xeeb rau thaum txhim kho cov kav dej hauv chav ua noj. Nws yog ib qho tsim nyog los xyuas kom meej qhov sib nrug ntawm cov kav dej thiab lub qhov cub. Yog tias tsis tuaj yeem zam tau, kev ntsuas thermal rwb thaiv tsev yuav tsum tau ua.
Thaum PVC-U cov kav dej yog siv rau hauv cov tsev siab. Qee cov kws tsim khoom thiab cov kws tshaj lij ua tsis tau raws li kev ntsuas los tiv thaiv kev nkag mus rau hluav taws raws li kev cai lij choj. Txoj hauv kev kom raug yog: raws li cov txheej txheem kev cai, tus riser yuav tsum tau teem rau hauv qhov qhib thiab nws txoj kab uas hla yuav tsum siab tshaj lossis sib npaug ntawm 110mm ~ l, - J, nyob rau hauv pem teb uas tus riser hla. Kev ntsuas yuav tsum tau ua kom tsis txhob muaj nplaim taws nkag; Thaum cov kab rov tav tso tawm cov kav dej uas muaj txoj kab uas hla ntau dua lossis sib npaug ntawm 110mil txuas nrog cov yeeb nkab zoo thiab cov riser hauv cov yeeb nkab, kev ntsuas los tiv thaiv cov nplaim hluav taws yuav tsum tau coj mus rau qhov chaw uas nws hla cov yeeb nkab zoo thiab cov yeeb nkab qhov phab ntsa. . Kab rov tav lub ntsiab yeeb nkab yuav tsum tsis txhob hla ntawm phab ntsa muab faib thiab firewall ntawm qhov hluav taws kub compartment; Thaum hla tsis tau, kev ntsuas los tiv thaiv cov nplaim hluav taws yuav tsum tau ua ntawm ob sab ntawm cov kav dej hla ntawm phab ntsa, xws li cov kav dej tsis muaj dej, lub nplhaib hluav taws, thiab lwm yam.
