Kev Tsim Nyog Rau Cov Hluav Taws Xob Hluav Taws Xob Underfloor

Raws li lub teb chaws thiab thoob ntiaj teb cov qauv khoom, cov khoom siv raw rau kev tsim cov kav dej yas thiab cov khoom siv yas rau cov dej txias thiab dej kub yuav tsum yog cov khoom siv tshwj xeeb uas tau dhau qhov kev txiav txim siab tsim nyog los ntawm kev sim ua raws li GB / T18252-2000 "Plastics Pipeline Cov Txheej Txheem - Kev txiav txim siab ntev Hydrostatic zog ntawm cov kav dej thermoplastic los ntawm Extrapolation". Qhov ntawd yog hais tias, txhua tus neeg tsim khoom siv raw khoom yuav tsum tsim kom muaj qhov tsis txaus ntseeg nkhaus uas ua tau raws li qhov kev kwv yees lub zog siv nkhaus raws li cov khoom siv hluav taws xob hauv pem teb kom ua pov thawj tias cov khoom muag muag tau tsim nyog. Ua ib qho kev ntsuas thermal stability nyob rau hauv static hydraulic siab ntawm 110 degree thiab 8760 teev tsis tuaj yeem ua pov thawj seb cov khoom siv raw ntawm cov yeeb nkab puas tsim nyog. Yog tias cov khoom siv raw khoom tsis paub tias tsim nyog, nws yog qhov sib npaug ntawm cov cement tsis muaj qib, thiab lub zog ntawm kev siv tsis tuaj yeem txiav txim siab. Tsis muaj teeb meem dab tsi ntawm cov yeeb nkab twg yog siv rau kev tso cua sov hauv pem teb, tsuas yog siv cov khoom siv raw uas ua tau raws li cov qauv ntawm cov khoom, thiab tsim cov kav dej tsim nyog nrog cov khoom tsim nyog thiab cov txheej txheem, thiab los ntawm kev tsim, kev teeb tsa, thiab kev siv, tuaj yeem ua haujlwm. lub neej ntawm cov kav dej yas rau hauv pem teb hluav taws xob cua sov tau ntseeg tau tias yuav tsum tau tsib caug xyoo.
