Tshuaj tua kab nruab nrab

Tshuaj tua kab yog ib qho tseem ceeb ntawm kev tsim khoom hauv kev ua liaj ua teb, uas ua lub luag haujlwm tseem ceeb hauv kev tswj cov kab mob, kab tsuag thiab nroj tsuag, stabilizing thiab txhim kho qoob loo.

Txawm hais tias cuam tshuam los ntawm tus nqi ntawm cov khoom ua liaj ua teb, thaj chaw cog qoob loo, huab cua, cov khoom muag thiab lwm yam, kev muag tshuaj tua kab yuav nthuav tawm qee qhov kev hloov pauv ntawm xyoo mus rau xyoo, tab sis qhov kev thov tseem tseem nruj.

Raws li cov ntaub ntawv los ntawm National Bureau of Statistics, kev tsim cov tshuaj tua kab hauv lub tebchaws tau pom tias muaj kev poob qis txij li xyoo 2017.
Xyoo 2017, cov khoom siv tshuaj tua kab tau poob rau 2.941 lab tons, tab sis xyoo 2018 nws poob rau 2.083 lab tons. Hauv xyoo 2019, cov khoom tsim tawm ntawm cov tshuaj tua kab tau nres thiab nce mus rau 2.2539 lab tons, nce 1.4 feem pua ​​​​rau xyoo.

Nyob rau hauv xyoo tas los no, Tuam Tshoj cov tshuaj tua kab kev lag luam muag cov nyiaj tau los tag nrho khaws cia ib qho zuj zus.
Xyoo 2018, ua tsaug rau kev tsim cov tshuaj tua kab mob lom thiab kev nce hauv cov khoom lag luam, nrog rau kev nthuav dav ntawm kev thov tshuaj tua kab hauv cov qoob loo nyiaj ntsuab xws li paj rwb thiab kev tsim kho vaj tse, kev lag luam muag cov nyiaj tau los ntawm 329 billion yuan.
Nws tau kwv yees tias qhov muaj peev xwm ua lag luam loj ntawm Tuam Tshoj txoj kev ua liaj ua teb tseem xav tias yuav nce ntxiv hauv 2020.

Cov tshuaj tua kab sib txawv xav tau cov intermediates sib txawv hauv cov txheej txheem tsim khoom.
Ib yam khoom uas ua los ntawm kev ua liaj ua teb raw cov ntaub ntawv kuj yog ib qho nruab nrab nruab nrab uas muab ob los yog ntau yam khoom ua ke.
Hauv cov tshuaj tua kab tuaj yeem nkag siab tias yog synergist, tseem hu ua organic intermediates.
Keeb kwm yog hais txog kev siv cov thee tar lossis roj av ua cov khoom siv raw rau kev sib xyaw ntawm cov txuj lom, dyes, resins, tshuaj, plasticizers, roj hmab accelerator thiab lwm yam khoom siv tshuaj, tsim nyob rau hauv cov txheej txheem ntawm cov khoom nruab nrab.

Lub synthesis ntawm intermediates feem ntau yog nqa tawm nyob rau hauv lub reactor, thiab cov generated intermediates yog sib cais thiab purified, feem ntau yog los ntawm extraction technology.
Cov tshuaj tua kab nruab nrab thiab chloroform extraction yog tshuaj lom neeg kev lag luam ua haujlwm ua haujlwm, cov txheej txheem kev ua haujlwm ib txwm siv feem ntau siv cov kab ke distillation, cov txheej txheem kev ua haujlwm zoo li no nyuaj, tsis tshua muaj txiaj ntsig, kev siv hluav taws xob loj, yog li nrog kev sib sib zog nqus ntawm kev sib faib ntawm kev ua haujlwm thiab cov kev nce qib ntawm kev siv tshuab ntau lawm, feem ntau cov tuam txhab lag luam pib hloov kho thev naus laus zis, thiab xaiv cov txheej txheem ua haujlwm zoo dua.
