PVC yog ib qho ntawm tsib universal resin cov ntaub ntawv, nrog rau cov yam ntxwv zoo xws li cov kua qaub thiab alkali tsis kam, hnav tsis kam, nplaim retardancy, thiab rwb thaiv tsev.Tam sim no, nws tau dhau los ua cov khoom yas thib ob hauv ntiaj teb tom qab polyethylene.
1.Lub peev xwm tsim khoom hauv tsev thiab cov zis ntawm PVC
Cov txheej txheem tsim khoom ntawm PVC feem ntau suav nrog ob txoj hauv kev: calcium carbide txoj kev thiab ethylene txoj kev, nrog rau qhov sib txawv tseem ceeb yog txoj kev npaj ntawm vinyl chloride monomer.
Los ntawm qhov kev xav ntawm ntau lawm nyob rau hauv xyoo tas los no, PVC ntau lawm tau qhia ib tug zuj zus trending xyoo los ntawm lub xyoo, thiab tag nrho cov kev lag luam lub peev xwm ntau lawm tau nkag mus rau hauv ib tug rational txoj kev loj hlob theem.Kev lag luam xav tau maj mam rov qab los, thiab kev tsim khoom tau nce tsis tu ncua.Raws li cov ntaub ntawv los ntawm Tuam Tshoj Chloroalkali Network, tag nrho cov kev khiav hauj lwm tus nqi ntawm Tuam Tshoj txoj kev lag luam PVC tau tseem nyob saum 50% nyob rau hauv xyoo tas los.
2. Txoj Kev Txhim Kho ntawm PVC Kev Lag Luam
(1) Txhim kho kev tsim kho cov khoom siv sib xyaw ua ke
Txij li thaum xyoo 2007, lub teb chaws tau tsim ntau cov kev cai uas muab cov kev cai ntxaws ntxaws rau kev txhim kho kev lag luam PVC.Nyob rau tib lub sijhawm, nws txhawb kev tsim kho cov cuab yeej txhawb nqa rau calcium carbide thiab chlor alkali ntau lawm cov tuam txhab, thiab ntxiv dag zog rau kev tsim kho cov khoom siv sib xyaw ua ke.Raws li kev coj noj coj ua ntawm lub tebchaws tam sim no, kev tsim cov khoom siv sib xyaw ua ke tau dhau los ua ib qho kev tsis pom kev nyob rau hauv nruab nrab thiab sab hnub poob ntawm Tuam Tshoj, uas yog nplua nuj nyob rau hauv thee, ntsev mines, thiab limestone peev txheej.Raws li lub luag haujlwm ntawm cov khoom siv sib xyaw ua ke, los ntawm kev cia siab rau cov khoom siv nplua nuj thiab cov txiaj ntsig zoo sib xws, cov nqi tsim khoom tuaj yeem tswj tau zoo thiab ntau yam los ntawm cov khoom tuaj yeem rov ua dua tshiab, Txhim kho kev lag luam kev sib tw thiab kev muaj peev xwm ntawm kev lag luam.
(2) Ntau cov txheej txheem ntau lawm
Nyob rau hauv lub tam sim no txoj kev loj hlob ntawm domestic PVC tuam txhab, qhov tseem ceeb ntawm kev sib txawv ntawm ntau lawm txheej txheem yog tas li nce, uas ua rau lawv cov kev xav tau ntawm kev siv tshuab qib siab.Txoj kev sib txawv ntawm cov txheej txheem diversification yog unstoppable.Nrog rau kev txhim kho ntxiv ntawm cov txheej txheem tsim khoom hauv tsev PVC, cov tuam txhab yuav tsum tau maj mam siv qee cov txheej txheem tsim khoom tshiab thaum khaws cov txheej txheem calcium carbide qub.Tib lub sijhawm, PVC polymerization thev naus laus zis kuj tseem yuav txhim kho tau zoo, tshwj xeeb tshaj yog nyob rau hauv cov nqe lus ntawm cov peev txheej ntawm cov khoom siv polymerization reactors.Tsis tas li ntawd, nws tseem yog ib qho tsim nyog yuav tsum nquag ua kom paub cov thev naus laus zis ntau lawm txawv teb chaws thiab maj mam txhawb lawv kom txhim kho kev lag luam kev lag luam.
