Nkag Siab Txog 3PE Cov Kav Hlau: Kev Txheeb Xyuas Tag Nrho

Hauv kev tsim kho niaj hnub thiab kev tsim kho vaj tse, qhov tseem ceeb ntawm cov khoom siv ruaj khov thiab txhim khu kev qha yog qhov pom tseeb. Ntawm lawv, 3PE steel kav (tseem hu ua peb txheej polyethylene tiv thaiv xeb steel kav) sawv tawm rau lawv cov kev ua tau zoo tshaj plaws thiab lub neej ua haujlwm ntev heev. Cov kav dej no, tsim los ntawm cov tuam txhab ua lag luam xws li Jindalai Steel Group, tau tsim los ua tib zoo kom tiv taus cov xwm txheej ib puag ncig hnyav thiab muaj kev tiv thaiv xeb zoo heev. Cov txheej txheem tsim cov kav hlau 3PE yog ua tib zoo thiab ua tib zoo, kom ntseeg tau tias cov qauv zoo tshaj plaws tau ua tiav. Ua ntej, cov kav hlau raug kho saum npoo, suav nrog kev ntxuav thiab tshem tawm cov kuab paug uas yuav cuam tshuam rau kev ncaj ncees ntawm cov txheej. Tom qab ntawd los txog cov qauv tiv thaiv xeb: thawj txheej yog hmoov epoxy (FBE): nrog rau qhov tuab ntau dua 100um, nws muaj kev nplaum zoo heev thiab tiv thaiv xeb, tiv thaiv cov yam ntxwv sab nraud xws li dej noo thiab cov pa roj los ntawm kev ua rau cov kav hlau xeb. Txheej thib ob yog nplaum (AD): cov nplaum copolymer nrog cov pab pawg ua haujlwm branched, ntawm 170-250um tuab, uas txuas cov txheej hmoov epoxy thiab txheej polyethylene, kom ntseeg tau tias muaj kev sib txuas nruj ntawm peb txheej. Txheej thib peb, polyethylene (PE), yog 1.8-3.7 hli tuab thiab muaj kev tiv thaiv xeb zoo heev, dej ua pa permeability tsis kam, thiab cov khoom siv kho tshuab, tiv thaiv cov kav hlau los ntawm kev cuam tshuam ib puag ncig. Cov txheej ntau txheej no tsis tsuas yog txhim kho cov kav hlau ruaj khov tab sis kuj tseem ua rau nws lub neej ua haujlwm ntev dua. Cov kav hlau 3PE siv dav thiab yog qhov kev xaiv zoo tshaj plaws rau ntau yam lag luam. Cov kav hlau no feem ntau siv rau kev thauj roj thiab roj av, cov txheej txheem xa dej, thiab kev kho dej khib nyiab. Lawv cov qauv ruaj khov thiab kev tiv thaiv xeb zoo heev ua rau lawv zoo tagnrho rau kev teeb tsa hauv av, qhov twg cov kav hlau ib txwm muaj feem yuav xeb sai hauv cov av noo thiab av noo. Ntxiv mus, cov kav hlau 3PE tiv thaiv xeb tau siv ntau dua hauv cov haujlwm hluav taws xob rov ua dua tshiab, xws li geothermal thiab cua fais fab, qhov twg kev ntseeg tau thiab lub neej ua haujlwm tseem ceeb heev. Kev kho qhov chaw yog qhov tseem ceeb rau kev ua haujlwm ntawm 3PE cov kav hlau. Kev kho qhov chaw pib yog ib kauj ruam tseem ceeb kom ntseeg tau tias muaj kev sib txuas zoo ntawm epoxy primer thiab cov hlau substrate. Qhov no yog ua raws li kev siv peb txheej polyethylene txheej, cov txheej txheem thov uas tau tswj hwm nruj me ntsis kom ntseeg tau tias muaj qhov tuab thiab kev npog sib npaug. Kev kho qhov chaw kawg suav nrog kev kho txheej kom ua tiav qhov nyuaj tshaj plaws thiab tiv taus cov yam ntxwv ib puag ncig. Cov txheej txheem kho qhov chaw tiav no tsis yog tsuas yog txhim kho qhov zoo nkauj ntawm cov kav dej xwb tab sis kuj ua rau lawv muaj zog tiv taus corrosion thiab tiv taus kev puas tsuaj. Cov kav dej hlau 3PE tau tsim los nrog lub zog siab tshaj plaws thiab kev ruaj khov. Cov txheej hlau sab hauv muab cov qauv tsim nyog, thaum cov txheej polyethylene peb txheej tiv taus cov tshuaj corrosive. Kev sib xyaw ua ke no ua rau cov kav dej tsis yog tsuas yog muaj zog xwb tab sis kuj sib dua, ua rau yooj yim tuav thiab teeb tsa. Ntxiv mus, qhov yooj ywm ntawm cov txheej polyethylene tso cai rau qib kev hloov pauv, txo qhov kev pheej hmoo ntawm kev tawg lossis tawg thaum muaj kev ntxhov siab. Xaus lus, cov kav hlau 3PE, tshwj xeeb tshaj yog cov kav hlau TPEP tiv thaiv xeb, sawv cev rau kev nce qib tseem ceeb hauv kev siv tshuab raj. Nrog lawv cov txheej txheem tsim khoom muaj zog, ntau yam kev siv, thiab cov thev naus laus zis kho kom zoo dua, lawv zoo tagnrho rau cov lag luam nrhiav kev daws teeb meem txhim khu kev qha thiab ruaj khov. Jindalai Steel Group txuas ntxiv ua tus thawj coj hauv kev tsim cov kav hlau tshiab no, xyuas kom meej tias lawv ua tau raws li cov qauv zoo tshaj plaws thiab kev ua tau zoo. Thaum cov kev xav tau ntawm cov khoom siv hauv paus loj hlob, qhov tseem ceeb ntawm cov ntaub ntawv siab heev no tsuas yog nce ntxiv, ua kom muaj zog rau txoj haujlwm tseem ceeb ntawm cov kav hlau 3PE hauv kev tsim kho niaj hnub thiab kev tsim kho.
