"Thaum nws los txog rau cov khoom siv hlau nthuav dav, tsuas yog kev txwv rau lawv cov ntawv thov nyob hauv tib neeg lub tswv yim," hais tias Ming Qin, Tus Thawj Coj ntawm Dongjie Facrory.

Raws li cov chaw tsim khoom nrog ntau tshaj 24 xyoo ntawm kev paub hauv kev tsim cov khoom siv hlau nthuav dav, kev ruaj ntseg tes rails, pem teb gratings thiab stair treads, lub tuam txhab tseem tsis tau ntsib ib qho kev txwv rau thaj tsam ntawm daim ntawv thov rau lawv cov khoom.

Cov khoom siv hlau nthuav dav thiab lawv cov kev siv cuam tshuam tuaj yeem sib txawv los ntawm peb cov kev lag luam nrov heev ntawm cov meshes - feem ntau yog siv los ua txoj kev taug kev, kev tshuaj ntsuam xyuas, rau cov roj lim encasements;thiab me me aperture meshes uas yog siv los ua tus hais lus npog, nas tswj hauv xov tooj yees, lossis los tiv thaiv hnub ci geysers los ntawm lawg - thiab txhua yam nyob nruab nrab, "Ming Qin hais.

Cov hlau nthuav dav kuj tseem muaj npe nrov hauv kev siv vaj tse, qhov chaw ua haujlwm zoo li lub suab nrov thiab lub teeb deflection ua ke nrog cov txiaj ntsig zoo nkauj nthuav.

Muaj qhov laj thawj zoo rau qhov muaj koob meej ntawm cov kab no.Expanded hlau muaj qee qhov zoo nkauj zoo nkauj.Nws muaj qhov hnyav-rau-lub zog piv zoo heev, thiab muaj qhov zoo dua ntawm cov khoom siv welded, cov khoom tsis muaj cov ntsiab lus tsis muaj zog hauv zos vim nws yog tsim los ntawm ib daim ntawv hlau.Nws yog tus nqi-zoo dua thiab cov khoom siv, kev tsim qauv, thiab cov khoom siv-rau-huab cua sib piv tuaj yeem ua raws li cov neeg siv khoom xav tau.

"Peb txaus siab rau peb tus kheej hauv kev tsim cov khoom lag luam zoo hauv ntiaj teb thiab mus rau mais ntxiv los pab peb cov neeg siv khoom nrhiav kev sib xyaw ua ke zoo tshaj plaws ntawm cov khoom siv thiab tsim qauv rau lawv cov kev xav tau tshwj xeeb: - txawm tias nws yog hlau me, tooj liab, lossis stainless hlau, txawv cov qauv, loj lossis me aperture.Peb lub xyoo dhau los ntawm kev paub - ua ke nrog lub siab ntawm kev tsim kho tshiab - tau coj mus rau kev txhim kho ntawm ntau yam khoom sib txawv.Ua piv txwv, peb tsuas yog cov neeg tsim khoom ntawm cov khoom tsis yog-dawb serrated taug kev mesh hauv Anping, Hebei, lub nroog ntawm cov hlau mesh "nws piav qhia.

Ming Qin txawm li cas los xij ceeb toom tias cov neeg siv khoom yuav tsum paub meej thaum xaiv cov khoom siv hlau nthuav dav, vim tias muaj qee qhov tsis pom kev tsis zoo xws li cov npoo ntse lossis cov kua muag me me hauv cov pob qij txha uas tuaj yeem yog qhov qhia txog kev cuam tshuam ntawm kev ncaj ncees.

Ntawm qhov tod tes, tuaj yeem muaj kev hloov pauv hauv cov khoom tuab uas yuav tshwm sim raws li cov khoom siv tsis zoo thaum, qhov tseeb, nws yog nyob rau hauv cov txheej txheem tsim khoom.Thaum cov kev hloov pauv no poob rau hauv cov khoom lag luam uas tau teev tseg nws yog qhov zoo li qub.Nws hais ntxiv rau cov neeg siv khoom kom ib txwm xaiv cov khoom lag luam uas ua raws li SANS lossis ISO cov qauv, thiab uas yog tsim los ntawm tus neeg muag khoom ntseeg siab nrog cov ntaub ntawv kev lag luam zoo.

Lub tuam txhab tau tsim nyog los muab lawv cov khoom rau ntau yam tshiab thiab zoo siab ua haujlwm tsis ntev los no.Qhov no suav nrog qee qhov kev tsim tshiab thee mines qhov twg Vitex nthuav dav hlau ntau tau siv rau kev tiv thaiv kev nyab xeeb ntawm lub tshuab thiab hauv kev tsim cov mine taug kev;nrog rau qee yam kev siv kev ruaj ntseg hauv cov mines kub.

"Peb zoo siab heev uas tau muab peb cov khoom siv hlau nthuav dav rau cov haujlwm no, vim qhov no qhia tau tias peb lub tuam txhab npe peb lub npe nthuav dav hlau 'Dongjie' tau dhau los ua qhov sib txawv ntawm cov khoom tsim kho tshiab thiab ntau yam - txhawb nqa los ntawm kev mob siab rau kev nyab xeeb thiab zoo," xaus lus.
