Cov yas yog siv dav thiab yog cov khoom tseem ceeb hauv cov khoom siv hauv tsev, tsheb, xov tooj ntawm tes, PCs, khoom siv kho mob, thiab cov khoom siv teeb pom kev zoo.Nrog txoj kev loj hlob ruaj khov thiab ruaj khov ntawm kuv lub teb chaws txoj kev lag luam, kev lag luam xws li cov khoom siv hauv tsev, tsheb, xov tooj ntawm tes, PCs, thiab cov cuab yeej kho mob kuj tau ua tiav kev loj hlob sai uas tau txais txiaj ntsig los ntawm ib puag ncig zoo.Txoj kev loj hlob ntawm downstream industries tau ntxiv txhawb qhov kev thov rau plastics.Nyob rau hauv 2010, muaj 2,286 tuam txhab uas muag nyob rau hauv Tuam Tshoj tus yas qhov chaw tsim kev lag luam, ib xyoo-rau-xyoo nce ntawm 24.54%;cov nyiaj tau los ntawm kev muag khoom tau mus txog 106.125 billion yuan, nce xyoo 26.38%.
Thaum lub sij hawm 12th Tsib Xyoo Plan, kuv lub teb chaws cov kev lag luam downstream xws li tsheb, khoom siv hauv tsev, cov neeg siv khoom siv hluav taws xob, thiab cov cuab yeej kho mob yuav txuas ntxiv txhim kho sai.Qhov kev thov rau cov khoom yas hauv cov kev lag luam no tseem yuav nthuav dav ntxiv, thiab qhov kev thov tseem yuav qhia txog qhov sib txawv ntawm high-end thiab precision.Nws tau kwv yees tias nyob rau lub sijhawm 12th Tsib Xyoo Kev Npaj, kev muag khoom ntawm Tuam Tshoj cov khoom lag luam yas yuav ncav cuag 170 billion yuan.Raws li CIC daim ntawv ntsuam xyuas, thev naus laus zis muaj peev xwm ntawm Tuam Tshoj cov khoom siv yas tsim kev lag luam tau raug txhim kho ntxiv, thiab cov tuam txhab thev naus laus zis R & D cov chaw tau nce ntxiv;cov qauv kev lag luam, cov qauv kev lag luam thiab cov khoom tsim tau raug hloov kho tas li, thiab kev siv zog ua haujlwm tau maj mam hloov kho;tag nrho cov txiaj ntsig ntawm kev lag luam tau raug txhim kho ntxiv thiab Kev Txhim Kho, qhov sib txawv nrog cov teb chaws tsim kho hauv ntiaj teb tau maj mam nqaim, thiab qee yam tau mus txog qib siab hauv ntiaj teb, nkag mus rau lub sijhawm tseem ceeb ntawm kev txhim kho kom ruaj khov los ntawm lub teb chaws loj mus rau qib siab. thiab lub teb chaws muaj zog.Cov khoom siv yas tsim kev lag luam hauv Jiangsu, Zhejiang, Shanghai, Guangdong thiab lwm qhov chaw yog booming.Ob tus naj npawb ntawm cov lag luam thiab cov nplai ntawm kev tsim khoom thiab kev muag khoom yog nyob rau hauv txoj hauj lwm ua nyob rau hauv lub teb chaws, thiab lub regional concentration ntawm kev lag luam yog kuj siab.
Nrog cov yas ua cov khoom siv tseem ceeb, ntau yam khoom siv yas lossis cov khoom siv yog tsim los ntawm kev siv thev naus laus zis xws li txhaj tshuaj, extrusion, thiab hollow molding.
Cov khoom yas yog ua los ntawm cov yas thiab polymerized los ntawm polyaddition los yog polycondensation, feem ntau hu ua yas los yog cob.Cov muaj pes tsawg leeg thiab cov duab tuaj yeem hloov pauv dawb.Nws yog tsim los ntawm hluavtaws resins thiab additives xws li muab tub lim, plasticizers, stabilizers, lubricants, thiab pigments.
Roj hmab tau muab faib ua cov roj hmab ntuj thiab hluavtaws roj hmab.
Cov roj hmab ntuj feem ntau yog muab los ntawm tsob ntoo Hevea sinensis.Thaum lub epidermis ntawm tsob ntoo roj hmab raug txiav, ib qho kua mis dawb yuav ntws tawm, hu ua latex.Cov latex yog coagulated, ntxuav, zoo li tus thiab qhuav kom tau cov roj hmab ntuj.
Cov roj hmab hluavtaws yog tsim los ntawm cov khoom siv hluavtaws, thiab cov roj hmab sib txawv tuaj yeem tsim los ntawm kev siv cov khoom sib txawv (monomers).
yam ntxwv
1) Tshuaj tiv thaiv
2) Feem ntau yog glossy.
3) Feem ntau ntawm lawv yog cov insulators zoo
4) Lub teeb yuag thiab muaj zog
5) Nws yog ib qho yooj yim rau txheej txheem thiab tuaj yeem ua ntau yam, thiab tus nqi pheej yig
6) Kev siv ntau yam, ntau lub zog, yooj yim rau xim, thiab qee qhov kub tsis kam
