Cov lus qhia luv luv ntawm cellulose ether

Cellulose ether yog ntuj cellulose (kua paj rwb thiab ntoo pulp, thiab lwm yam) raws li raw cov ntaub ntawv, tom qab etherification ntawm ntau yam derivatives, yog cellulose macromolecule hydroxyl hydrogen los ntawm ether pab pawg neeg ib nrab los yog tag nrho hloov tom qab tsim ntawm cov khoom, yog cov downstream derivatives. ntawm cellulose.Cellulose tuaj yeem yaj hauv dej, dilute alkali kua thiab cov kuab tshuaj organic tom qab etherification, thiab muaj cov khoom siv thermoplastic.Cellulose ether ntau yam, dav siv hauv kev tsim kho, cement, txheej, tshuaj, khoom noj, roj av, tshuaj niaj hnub, textile, ntawv thiab hluav taws xob thiab lwm yam lag luam.Raws li tus naj npawb ntawm cov hloov pauv tuaj yeem muab faib ua ib leeg ether thiab sib xyaw ether, raws li ionization tuaj yeem muab faib ua ionic cellulose ether thiab non-ionic cellulose ether.Tam sim no, ionic cellulose ether ionic cov txheej txheem tsim khoom yog paub tab, yooj yim ua thiab tus nqi qis, kuj tsis tshua muaj kev lag luam teeb meem, feem ntau yog siv rau hauv cov khoom noj khoom haus additives, textile additives, tshuaj niaj hnub thiab lwm yam kev lag luam, yog cov khoom tseem ceeb ntawm kev ua lag luam.

Tam sim no, lub ntiaj teb lub ntsiab cellulose ether yog CMC, HPMC, MC, HEC thiab lwm yam ntau, CMC cov zis yog qhov loj tshaj plaws, suav txog li ib nrab ntawm cov khoom siv thoob ntiaj teb, thaum HPMC thiab MC ob leeg suav txog li 33% ntawm lub ntiaj teb xav tau, HEC suav txog li 13% ntawm lub ntiaj teb ua lag luam.Qhov tseem ceeb tshaj plaws ntawm kev siv carboxymethyl cellulose (CMC) yog cov tshuaj ntxuav tes, suav txog li 22% ntawm cov khoom lag luam qis qis, thiab lwm yam khoom siv feem ntau yog siv hauv tsev, khoom noj khoom haus thiab tshuaj.

Ii.Daim ntawv thov hauv qab

Yav dhau los, vim qhov txwv tsis pub muaj kev loj hlob ntawm cellulose ether nyob rau hauv cov tshuaj niaj hnub, tshuaj, zaub mov, txheej thiab lwm yam kev lag luam hauv Suav teb, qhov kev thov rau cellulose ether hauv Suav teb yog qhov tseem ceeb hauv cov khoom siv hauv tsev, txog rau hnub no, lub tsev Cov ntaub ntawv kev lag luam tseem nyob 33% ntawm qhov kev thov rau cellulose ether hauv Suav teb.Thiab zoo li Tuam Tshoj lub cellulose ether nyob rau hauv lub teb ntawm lub tsev cov ntaub ntawv thov tau ua saturated, nyob rau hauv niaj hnub tshuaj, tshuaj, zaub mov, txheej thiab lwm yam kev thov yog loj hlob sai heev nrog rau kev loj hlob ntawm daim ntawv thov technology.Piv txwv li, nyob rau hauv xyoo tas los no, cov nroj tsuag capsule nrog cellulose ether yog cov khoom siv tseem ceeb, nrog rau cov khoom tsim tawm los ntawm cov nqaij dag nrog cellulose ether muaj kev xav tau dav dav thiab qhov chaw loj hlob.

Hauv kev tsim cov khoom siv hauv tsev, piv txwv li, cellulose ether nrog thickening, dej tuav, qeeb condensation thiab lwm yam ntxwv zoo heev, yog li cov ntaub ntawv hauv tsev qib cellulose ether yog siv los txhim kho kev ua haujlwm ntawm cov khoom siv hauv tsev nrog rau cov khoom sib xyaw ua ke (suav nrog ntub dej. sib xyaw mortar thiab qhuav mix mortar), PVC resin manufacturing, latex xim, putty, thiab lwm yam.. Ua tsaug rau kev txhim kho ntawm theem ntawm kev loj hlob nyob rau hauv Suav teb, kev loj hlob sai ntawm lub tsev cov ntaub ntawv kev lag luam, theem ntawm kev tsim kho tshuab txuas ntxiv txhim kho, thiab cov neeg siv khoom xav tau ib puag ncig rau cov khoom siv hauv tsev tau nce siab thiab siab dua, ua rau qhov kev thov rau cov khoom siv tsis yog-ionic cellulose ether hauv thaj chaw ntawm cov khoom siv hauv tsev.Thaum lub sij hawm 13th Tsib-Xyoo Plan lub sij hawm, Tuam Tshoj tau ceev lub renovation ntawm rundown cheeb tsam thiab cov tsev nyob rau hauv lub nroog, thiab ntxiv dag zog rau kev tsim kho ntawm lub nroog infrastructure, nrog rau kev ua kom lub renovation ntawm pab pawg neeg rundown cheeb tsam thiab cov zos nyob rau hauv lub nroog, thiab kev tswj kom muaj kev kho kom zoo ntawm lub nroog. cov vaj tse qub qub thiab kho dua tshiab ntawm cov tsev qub qub thiab cov tsev tsis tiav.Hauv thawj ib nrab ntawm 2021, 755.15 lab square metres ntawm thaj chaw nyob tau pib, nce 5.5 feem pua.Qhov chaw ua tiav ntawm vaj tsev yog 364.81 lab square meters, nce 25.7%.Qhov rov qab los ntawm thaj chaw ua tiav ntawm vaj tse yuav tsav qhov kev xav tau hauv thaj tsam ntawm cellulose ether cov ntaub ntawv hauv tsev.

3. Cov qauv kev sib tw ua lag luam

Tuam Tshoj yog lub ntiaj teb no cellulose ether ntau lawm lub teb chaws, nyob rau hauv lub tam sim no theem ntawm domestic tsev cov ntaub ntawv qib cellulose ether tau pib ua tiav localization, Anxin Chemistry ua lag luam nyob rau hauv lub teb ntawm cellulose ether, lwm yam loj domestic manufacturers kuj muaj xws li Kima tshuaj thiab lwm yam txheej txheej, tshuaj zaub mov qib cellulose ether tam sim no feem ntau yog Tebchaws Meskas Dow, Ashland, Nyiv shinetsu, Kaus Lim Qab Teb Lotte thiab lwm yam kev lag luam txawv teb chaws.Ntxiv rauAnxin chemistryob peb ntau tshaj kaum txhiab tons ntawm cov lag luam, ntau txhiab tons ntawm non-ionic cellulose ether cov chaw tsim khoom me me, feem ntau ntawm cov tuam txhab me no tsim cov qauv tsim cov khoom siv qib cellulose ether, thiab tsis muaj zog los tsim cov khoom noj khoom haus thiab tshuaj ntau dua.

Plaub, cellulose ether ntshuam thiab export xwm txheej

Xyoo 2020, vim muaj kev sib kis thoob ntiaj teb ua rau muaj kev lag luam txawv teb chaws poob qis, Tuam Tshoj cov cellulose ether xa tawm tau pom tias muaj kev loj hlob sai, hauv 2020 kom ua tiav cov khoom xa tawm ntawm cellulose ether 77,272 tons.Txawm hais tias lub ntim ntim ntawm cellulose ether hauv Suav teb loj hlob sai, cov khoom xa tawm feem ntau yog ua los ntawm cov khoom siv hauv tsev cellulose ether, thaum lub ntim ntim ntawm kev kho mob thiab noj tau cellulose ether tsawg heev, thiab tus nqi ntxiv ntawm cov khoom xa tawm tsawg.Tam sim no, export ntim ntawm cellulose ether nyob rau hauv Tuam Tshoj yog plaub npaug ntawm ntshuam ntim, tab sis lub export ntim yog tsawg tshaj li ob npaug ntawm cov nyiaj ntshuam.Nyob rau hauv lub tshav pob ntawm high-end khoom domestic cellulose ether export hloov txheej txheem tseem yog ib tug loj qhov chaw rau txoj kev loj hlob.
