Kev siv tseem ceeb ntawm cov khoom siv polyurethane tshiab

Niaj hnub no, cov khoom siv rwb thaiv tsev polyurethane paub rau txhua tus neeg ua cov khoom siv rwb thaiv tsev, feem ntau yog siv rau phab ntsa rwb thaiv tsev, cov yeeb nkab rwb thaiv tsev ob qhov chaw loj, xws li cov kav dej roj, cov kav dej thiab cov phab ntsa hauv tsev.

Polyurethane rwb thaiv tsev steel yeeb nkab tiv thaiv kev siv cov yeeb nkab steel raws li txheej txheej tiv thaiv, nrog lub zog siab.Tsis yooj yim rau kev puas tsuaj thiab tuaj yeem tiv taus cov yam ntxwv ntawm cov khoom loj dua, txhawm rau kom ua tiav lub neej ntev, cov yeeb nkab steel hlau yuav tsum tau kho los tiv thaiv corrosion.

Rolling kev txhawb nqa qauv tsim yog tsim nyog, dov kev sib txhuam me me, kev txhawb nqa ruaj khov yog txo, nws cov txheej txheem kev tshuaj ntsuam xyuas yooj yim, cov kav dej ruaj khov, kev ruaj ntseg tau txhim kho zoo heev.

Polyurethane rwb thaiv tsev steel yeeb nkab nqus txheej tshem tawm tag nrho cov huab cua txheej ntawm cua sov conduction thiab cua sov convection, zoo heev txo cov cua sov.Piv nrog rau cov txheej txheem huab cua, nyob rau tib lub rwb thaiv tsev thickness tuaj yeem txo cov phab ntsa sab nrauv 8-13° c.

Lub tshuab nqus tsev ua tiav daws qhov teeb meem ntawm cov phab ntsa sab hauv ntawm cov hlau sab nrauv tau yooj yim corroded los ntawm huab cua kub thiab ntub dej, uas zoo heev txhim kho lub neej ua haujlwm ntawm cov kav dej ncaj qha faus.Cov khoom lag luam tau nce mus txog 30 xyoo.

Polyurethane rwb thaiv tsev yeeb nkabyog siv rau ntau yam hauv tsev thiab sab nraum zoov pipelines, centralized cua sov pipelines, central cua txias pipelines, tshuaj, tshuaj thiab lwm yam industrial pipeline rwb thaiv tsev, txias preservation project.Txheej txheem cej luam polyurethane ua npuas ncauj rwb thaiv tsev yeeb nkab txij thaum yug los ntawm polyurethane hluavtaws cov ntaub ntawv nyob rau hauv lub thirties, tau ua ib tug zoo heev thermal rwb thaiv tsev cov ntaub ntawv thiab kev loj hlob sai, nws daim ntawv thov yog ntau thiab ntau, ntau vim hais tias ntawm nws yooj yim kev tsim kho, lub zog-txuag anti-corrosion nyhuv. thiab yog siv nyob rau hauv ib tug loj tus naj npawb ntawm ntau yam cua sov, tub yees, roj, chav thiab lwm yam pipelines.Nws yog siv rau hauv ntau qhov ntau hauv cov kav dej rau cua sov, cua txias, roj thiab chav sib kis, thiab lwm yam.

Cov txiaj ntsig nyiaj txiag ntawm kev siv cov ntaub ntawv tshiab polyurethane

Rwb thaiv tsev yeeb nkabyog ib qho tseem ceeb cuam tshuam rau kev txuag hluav taws xob, kev txhim kho thiab kev siv cov yeeb nkab rwb thaiv tsev tau nce zuj zus los ntawm cov teb chaws thoob ntiaj teb.Tom qab xyoo 1970, cov teb chaws txawv teb chaws feem ntau muab qhov tseem ceeb rau kev tsim khoom thiab kev siv cov yeeb nkab rwb thaiv tsev, thiab siv zog ua kom txo tau qhov kev siv hluav taws xob ntau, yog li txo cov pa phem ib puag ncig thiab cov nyhuv tsev cog khoom.Kev lag luam rwb thaiv tsev txawv teb chaws muaj keeb kwm ntev, thiab cov ntaub ntawv rwb thaiv tsev tshiab kuj tshwm sim.1980 xyoo dhau los, Tuam Tshoj txoj kev txhim kho cov yeeb nkab rwb thaiv tsev yog qeeb heev, ob peb lub rwb thaiv tsev tsuas tuaj yeem tsim tau me me ntawm cov yeeb nkab hauv av, tab sis Tuam Tshoj txoj kev lag luam rwb thaiv tsev tom qab 30 xyoo ntawm kev siv zog, tshwj xeeb tshaj yog tom qab ze li 10 xyoo ntawm kev loj hlob sai, ntau cov khoom los ntawm tsis muaj dab tsi kom muaj, los ntawm ib leeg mus rau ntau haiv neeg, zoo los ntawm qis mus rau siab, Daim Ntawv Thov tau dhau los ua ntau dua.Cov khoom siv polyurethane tam sim no yog cov khoom siv rwb thaiv tsev feem ntau siv nyob rau hauv thoob ntiaj teb arena.Rigid polyurethane muaj ntau yam zoo heev thiab yog dav siv nyob rau hauv cov teb chaws Europe thiab lub tebchaws United States nyob rau hauv lub tshav pob ntawm thermal rwb thaiv tsev.Txog 49% ntawm cov ntaub ntawv rwb thaiv tsev nyob hauv Europe thiab Tebchaws Meskas thiab lwm lub tebchaws tsim yog cov ntaub ntawv polyurethane, thaum nyob hauv Suav teb qhov kev faib ua feem tseem tsawg dua 20%.Yog li ntawd, tseem muaj ntau chav rau kev tsim cov khoom siv polyurethane rwb thaiv tsev hauv Suav teb.

Yog li, kuv tau qhia txog kev siv lub ntsiab ntawm cov khoom siv polyurethane tshiab, uas tau ua kom muaj kev txhim kho zoo rau kev ua haujlwm ntawm cov rwb thaiv tsev ntawm cov yeeb nkab rwb thaiv tsev, thiab kuj txo qhov kub poob ntawm cov yeeb nkab rwb thaiv tsev, thiab txhim kho kev ua haujlwm ntawm Lavxias teb sab.Nws kuj muaj qhov zoo ntawm kev tsim kho yooj yim, tus nqi qis thiab ntau lwm yam zoo, dhau los ua cov kav dej ntau yam khoom nyiam heev.Kuv ntseeg tias tom qab cov khoom siv polyurethane tshiab yuav txuas ntxiv siv rau hauv thaj chaw tshiab, cov ntaub ntawv tshiab polyurethane tshiab kuj tseem yuav tsim.
