Nrog rau kev qhia txog Txoj Kev Npaj Tsib Xyoos Thib Kaum Ob, kuv lub teb chaws txoj kev loj hlob hauv nroog yuav nrawm dua txhua xyoo. Txhua 1% kev nce hauv nroog yuav xav tau 3.2 billion cubic meters ntawm kev siv dej hauv nroog. Yog li ntawd, cov yeeb nkab yas tseem xav tias yuav tswj tau qhov nruab nrab txhua xyoo ntawm 15%. Kev loj hlob ntawm kwv yees li %.

Cov kav dej yas hauv Suav teb tau tsim los ua ib pawg tseem ceeb ntawm cov khoom yas. Cov khoom siv tshuaj lom neeg hauv tsev yog hom khoom siv tshiab thib plaub uas tshwm sim hauv lub sijhawm niaj hnub no tom qab hlau, ntoo, thiab cement. Cov kav dej yas, cov yas profile, qhov rooj thiab qhov rai yog ob hom khoom siv tshuaj lom neeg tseem ceeb hauv tsev uas siv ntau zaus. Txij li xyoo 1994, tsoomfwv Suav tau koom ua ke los ntawm Ministry of Construction, yav dhau los Ministry of Chemical Industry, yav dhau los China National Light Industry Council, National Building Materials Bureau, thiab yav dhau los China Petrochemical Corporation los koom ua ke "National Chemical Building Materials Coordination Leading Group" los tsim thiab tshaj tawm cov kev siv zog. Kev tsim cov hom phiaj, cov phiaj xwm, cov cai, cov qauv, thiab lwm yam ntawm cov khoom siv tshuaj lom neeg hauv tsev. Hauv ob peb xyoos xwb, Tuam Tshoj cov kav dej yas, cov yas profile, qhov rooj thiab qhov rai tau ua tiav kev loj hlob sai. Xyoo 1994, lub teb chaws muaj peev xwm tsim cov yeeb nkab yas yog 240,000 tons, thiab cov zis yog 150,000. Xyoo 2000, lub peev xwm yog 1.64 lab tons, thiab cov zis yog 1 lab tons (uas cov zis ntawm PVC-U yeeb nkab yog li 500,000 tons), cov kab tsim yeeb nkab tau mus txog ntau dua 2,000, thiab qhov loj ntawm cov yeeb nkab polyvinyl chloride nyuaj yog ntau dua 10,000 tons. Muaj ntau dua 30 lub tuam txhab thoob plaws lub teb chaws.

Cov yeeb nkab network ib txwm muaj feem ntau yog cov yeeb nkab hlau, cov yeeb nkab hlau cam khwb cia, cov yeeb nkab cement thiab cov yeeb nkab av nplaum. Cov ntaub ntawv yeeb nkab ib txwm muaj cov yam ntxwv ntawm kev siv hluav taws xob ntau thiab kev ua qias tuaj rau ib puag ncig. Tib lub sijhawm, cov yeeb nkab network kuj muaj cov qhov tsis zoo hauv qab no: ① Lub neej luv luv, feem ntau 5-10 xyoo; ② Tsis kam tshuaj lom neeg thiab tsis kam xeb; ③ Kev ua haujlwm hydraulic tsis zoo; ④ Tus nqi tsim kho siab, lub sijhawm ntev; ⑤ Kev ua haujlwm ntawm cov yeeb nkab tsis zoo, yooj yim xau, thiab lwm yam. Txij li nruab nrab ntawm lub xyoo pua 20th, cov tebchaws thoob ntiaj teb, tshwj xeeb tshaj yog cov tebchaws tsim kho, tau tsim cov khoom siv tshwj xeeb rau cov yeeb nkab yas thiab siv cov yeeb nkab yas.

Nyob rau kaum xyoo dhau los no, cov kav dej yas tau tsim kho sai heev. Cov kav dej yas tau nrov zuj zus vim lawv txoj kev tiv thaiv ib puag ncig thiab kev nyab xeeb hauv lub neej txhua hnub thiab kev siv hauv kev lag luam, thiab lawv ua lub luag haujlwm tseem ceeb thiab tsis tuaj yeem hloov pauv tau. Tshwj xeeb tshaj yog hauv kev lag luam kev tsim kho, cov kav dej yas tsis tsuas yog hloov cov hlau, ntoo, thiab cov ntaub ntawv tsim kho ib txwm muaj ntau xwb, tab sis kuj muaj qhov zoo ntawm kev txuag hluav taws xob, kev txuag khoom siv, kev tiv thaiv ib puag ncig, kev txhim kho ib puag ncig, kev txhim kho kev ua haujlwm thiab zoo ntawm lub tsev, txo qhov hnyav ntawm lub tsev, thiab kev ua tiav yooj yim. , Siv dav hauv kev tsim dej thiab dej ntws, kev muab dej hauv nroog thiab dej ntws, cov kav dej roj thiab lwm yam teb; qhov kev loj hlob ntawm cov kav dej yas yog kwv yees li 4 npaug ntawm qhov nruab nrab ntawm cov kav dej, uas siab dua qhov kev loj hlob ntawm lub teb chaws kev lag luam ntawm ntau lub teb chaws. Kev hloov cov kav hlau cam khwb cia thiab cov kav hlau galvanized nrog cov kav dej yas ntsuab uas tsis muaj kuab paug tau dhau los ua qhov sib txawv ntawm kev txhim kho hauv lub xyoo pua tshiab. Cov kav dej yas tau tsim kho zoo thiab siv dav hauv cov teb chaws tsim kho, tshwj xeeb tshaj yog hauv Tebchaws Europe; kev txhim kho hauv kuv lub teb chaws tau qeeb heev, tab sis nyob rau xyoo tas los no, nrog rau kev txhim kho ntawm kuv lub teb chaws lub zog thoob plaws lub teb chaws thiab kev txhim kho ntawm cov neeg lub neej, cov kav dej yas tau ua tiav sai. kev txhim kho ntawm.

Cov yeeb nkab yas ntau yam thiab cov ntawv thov tau tsim kho sai heev hauv ob peb xyoos dhau los. Tam sim no, kuv lub teb chaws cov yeeb nkab yas tau tsim kho mus rau hauv kev lag luam khoom siv hauv tsev nrog ntau yam tiav thiab muaj peev xwm tsim khoom loj. Cov yeeb nkab yas tseem ceeb yog: UPVC yeeb nkab,Cov kav dej CPVC, thiab cov kav dej PE. , PAP yeeb nkab, PE-X yeeb nkab, PP-B yeeb nkab,PP-R yeeb nkab, PB yeeb nkab, ABS yeeb nkab,yeeb nkab hlau-yas sib xyaw, cov yeeb nkab fiber iav, thiab lwm yam. Nws yog siv dav hauv cov kav dej thiab cov kav dej ntws rau kev tsim kho, cov kav dej hauv nroog, cov kav dej ntws, cov kav roj, cov kav dej thiab cov kav dej ntws rau thaj chaw nyob deb nroog, cov kav dej ywg dej, thiab cov dej phwj hauv kev lag luam thiab kev thauj mus los ntawm cov kua tshuaj, thiab lwm yam, ua tau raws li qhov xav tau ntawm ntau qhov chaw ntawm lub teb chaws kev lag luam. Cov kev xav tau sib txawv ntawm cov kav dej. Peb yuav tsum tsim thiab tsim ib hom yeeb nkab yas raws li cov yam ntxwv thiab kev siv ntawm ntau yam yeeb nkab.
