Nrog rau kev txhim kho tas mus li ntawm kev ua lag luam, ntau thiab ntau cov khoom raug muab tso rau hauv kev tsim khoom, thiab cov kab tsim cov yeeb nkab yas kuj tau txhim kho nrog kev tshawb fawb thiab kev txhim kho tas mus li, thiab nws yog ntau dua nyob rau hauv kab nrog cov kev xav tau ntawm kev tsim kho niaj hnub thiab kev tsim kho. Qib ntawm cov thev naus laus zis tau txhim kho, thiab qhov zoo ntawm cov khoom muaj kev nyab xeeb thiab txhim khu kev qha. Lub zeem muag kev loj hlob yog dav heev.
Ua ib feem tseem ceeb ntawm cov khoom siv tshuaj lom neeg hauv tsev, cov kav dej yas tau txais kev lees paub dav los ntawm cov neeg siv rau lawv qhov kev ua tau zoo tshaj plaws, kev huv huv, kev tiv thaiv ib puag ncig, thiab kev siv tsawg. Lawv feem ntau suav nrog UPVC thiabUPVC pob valve,Kev muab dej UPVC, cov kav dej txhuas-yas sib xyaw, thiab polyethylene (PE). Cov hom kav dej no. Cov kab ntau lawm kav dej muaj ib lub kaw lus tswj, ib lub extruder, lub taub hau tshuab, lub kaw lus txias, lub tsheb laij teb, lub cuab yeej txiav planetary thiab lub thav duab tig.
Raws li kev soj ntsuam, feem ntawm kev ua lag luam ntawm kuv lub teb chaws cov yeeb nkab yas tseem ceeb suav txog 96% ntawm tag nrho cov yeeb nkab cua sov thiab dej kais niaj hnub. Qhov zoo dua yog pom tseeb dua lwm cov ntaub ntawv, thiab tus nqi siv yuav txuas ntxiv mus rau qhov nce ntxiv hauv ob peb xyoos tom ntej. Ntawm lawv, cov yeeb nkab yas yuav tsis nkag mus rau qib ntawm kev hloov pauv hauv ob peb xyoos tom ntej vim tias cov khoom tsis tshua muaj kev tiv thaiv corrosion thiab siv sijhawm ntev. Yog li ntawd, cov chaw tsim khoom tseem ceeb tam sim no feem ntau yog cov lag luam tshiab, xws li geothermal, cov yeeb nkab huv thiab lwm yam kev tsim kho.
Cov yeeb nkab yas muaj qhov zoo ntawm kev tiv thaiv corrosion thiab tus nqi qis, thiab tau dhau los ua ib qho ntawm cov yeeb nkab siv dav tshaj plaws. Cov kab ntau lawm yeeb nkab yas muaj peev xwm tsim cov khoom siv yeeb nkab sai sai, ua rau cov khoom tsim kho sai, thiab hloov kho tas li rau cov kev xav tau ntawm kev ua lag luam, thiab tsim tshwj xeeb rau lub tuam txhab. Zoo heevcov kav dej yasnyob feem ntau ntawm cov yeeb nkab lag luam.
