Lub Tuam Txhab Zoo Dua

Nyob hauv plawv nroog Cangzhou, xeev Hebei, peb lub Hoobkas tau yog lub hauv paus ntawm kev lag luam hlau txij li thaum nws tau tsim tsa xyoo 1993. Lub Hoobkas npog thaj tsam ntawm 350,000 square meters thiab muaj cov cuab yeej siv thev naus laus zis thiab tshuab, ua rau peb tsim cov khoom siv hlau zoo uas ua tau raws li cov qauv thoob ntiaj teb. Nrog rau tag nrho cov cuab tam ntawm RMB 680 lab, peb muaj 680 tus neeg ua haujlwm txawj ntse mob siab rau kev muab kev ua tau zoo hauv txhua yam ntawm peb cov haujlwm.

Qhov zoo ntawm cov khoom

Ua ntej, nws cov duab cylindrical tso cai rau kev faib khoom zoo, ua rau nws zoo tagnrho rau kev siv hauv paus tob. Cov qauv hlau muab lub zog tshwj xeeb thiab kev ruaj khov, ua kom ntseeg tau tias cov pawg no tuaj yeem tiv taus cov khoom loj thiab cov xwm txheej ib puag ncig hnyav. Tsis tas li ntawd, qhov ua tau ntau yam ntawm ASTM A252 yeeb nkab tso cai rau nws siv rau ntau yam kev siv, los ntawm cov choj mus rau cov tsev, ua rau nws nyiam cov engineers thiab cov neeg cog lus.

Qhov Tsis Zoo ntawm Khoom

Ib qho tsis zoo uas pom tseeb yog qhov muaj peev xwm ua rau xeb, tshwj xeeb tshaj yog nyob rau hauv cov chaw uas muaj av noo siab lossis raug tshuaj lom neeg. Txawm hais tias cov txheej tiv thaiv tuaj yeem txo qhov teeb meem no, lawv tuaj yeem ua rau cov nqi tag nrho thiab cov kev xav tau kev saib xyuas nce ntxiv.

Tsis tas li ntawd, cov txheej txheem tsim khoom rauASTM A252cov yeeb nkab tuaj yeem siv cov peev txheej ntau, uas yuav ua rau muaj kev txhawj xeeb txog kev ruaj khov thiab kev cuam tshuam rau ib puag ncig.

Daim Ntawv Thov
