1. Chidule Chachidule cha Cellulose Ether
Ma cellulose ether ndi mawu omwe amagwiritsidwa ntchito pamitundu yosiyanasiyana yochokera ku cellulose yachilengedwe (thonje woyengedwa ndi zamkati zamatabwa, ndi zina zambiri.) Zotsatira zake ndizochokera kumunsi kwa cellulose. Pambuyo pa etherification, mapadi amatha kusungunuka m'madzi, kusungunula alkali solution ndi organic solvent, ndipo amakhala ndi thermos plasticity. Pali mitundu yambiri ya ma cellulose ethers, omwe amagwiritsidwa ntchito kwambiri pomanga, simenti, utoto, mankhwala, chakudya, mafuta, mankhwala a tsiku ndi tsiku, nsalu, kupanga mapepala ndi zipangizo zamagetsi ndi mafakitale ena. Malinga ndi kuchuluka kwa zolowa m'malo, zimatha kugawidwa kukhala ether imodzi ndi ether yosakanikirana, ndipo malinga ndi ionization, imatha kugawidwa kukhala ionic cellulose ether ndi non-ionic cellulose ether. Pakalipano, mankhwala a ionic cellulose ether ionic ali ndi luso lopanga kupanga, kukonzekera kosavuta, mtengo wotsika, komanso zolepheretsa makampani otsika. Amagwiritsidwa ntchito kwambiri pazowonjezera chakudya, zowonjezera zovala, mankhwala atsiku ndi tsiku ndi magawo ena, ndipo ndizomwe zimagulitsidwa pamsika. mankhwala.
2. Ntchito yayikulu ndi ntchito ya cellulose ether
Pakalipano, ma ether a cellulose padziko lonse lapansi ndi CMC, HPMC, MC, HEC, ndi zina zotero. Pakati pawo, CMC ili ndi zotsatira zazikulu kwambiri, zomwe zimawerengera pafupifupi theka la zinthu zonse zapadziko lonse, pamene HPMC ndi MC onse amawerengera pafupifupi 33% ya dziko lonse lapansi. kufunika, ndipo HEC imawerengera pafupifupi 30% ya zomwe zikufunika padziko lonse lapansi. 13% ya msika. Kugwiritsidwa ntchito kofunikira kwambiri kwa carboxymethyl cellulose (CMC) ndi zotsukira, zomwe zimawerengera pafupifupi 22% yazomwe zimafunikira pamsika, ndipo zinthu zina zimagwiritsidwa ntchito makamaka pantchito zomanga, chakudya ndi mankhwala.
Padziko Lonse Ma cellulose Ether Amafuna Kuwonongeka ndi Zogulitsa
3. Mapulogalamu akumunsi
M'mbuyomu, chifukwa cha chitukuko chochepa cha zofuna za dziko langa za cellulose ether m'minda ya mankhwala a tsiku ndi tsiku, mankhwala, chakudya, zokutira, etc., kufunika kwa cellulose ether m'dziko langa kunali kokhazikika m'munda wa zipangizo zomangira. Mpaka lero, makampani opanga zida zomangira akadali 33% ya zofuna za cellulose ether za dziko langa. %. Kufunika kwa dziko langa cellulose ether m'munda wa zipangizo zomangira wakhala anakhuta, ndi kufunika m'minda ya tsiku ndi tsiku mankhwala, mankhwala, chakudya, zokutira, etc. ikukula mofulumira ndi chitukuko cha luso ntchito. Mwachitsanzo, m'zaka zaposachedwa, makapisozi obzala okhala ndi cellulose ether monga chopangira chachikulu, ndi nyama yokumba, yomwe ikubwera yopangidwa ndi cellulose ether, ili ndi chiyembekezo chofuna zambiri komanso malo okulirapo.
Gawo la magawo osiyanasiyana amsika akumunsi a cellulose ether m'dziko langa
Kutengera gawo la zida zomangira mwachitsanzo, cellulose ether ili ndi zinthu zabwino kwambiri monga kukhuthala, kusunga madzi, ndi kuchedwa. Choncho, zomangira kalasi cellulose ether chimagwiritsidwa ntchito bwino kupanga matope okonzeka-osakaniza (kuphatikizapo chonyowa wothira matope ndi youma wothira matope), PVC utomoni, etc., latex utoto, putty, etc., kuphatikizapo ntchito ya zomangira zakuthupi. Tithokoze chifukwa chakukula kwa mizinda yadziko langa, kukula mwachangu kwamakampani opanga zida zomangira, kuwongolera kosalekeza kwamakina omanga, komanso kuchuluka kwachitetezo chachitetezo kwa ogula pazida zomangira kwachititsa kuti ma cellulose ethers omwe si a ionic apite patsogolo. m'munda wa zomangira. M’nyengo ya 13th Year Plan Plan, dziko langa linafulumizitsa kukonzanso midzi ya m’tauni ndi nyumba zowonongeka, ndi kulimbikitsa ntchito yomanga m’matauni, kuphatikizapo kufulumizitsa kusintha kwa midzi ya m’matauni ndi m’midzi, mwadongosolo kulimbikitsa kukonzanso kotheratu kwa nyumba zakale zogonamo, nyumba zakale zowonongeka ndi ma seti osakwanira Kukonzanso nyumba ndi zina zambiri. Mu theka loyamba la 2021, malo okhalamo nyumba zogona kumene anali 755.15 miliyoni masikweya mita, kuwonjezeka kwa 5.5%. Malo omalizidwa a nyumba anali 364.81 miliyoni masikweya mita, kuwonjezeka kwa 25.7%. Kubwezeretsedwa kwa malo omalizidwa a malo ogulitsa nyumba kudzayendetsa kufunikira kogwirizana ndi gawo la zida zomangira za cellulose ether.
4. Chitsanzo cha mpikisano wa msika
Dziko langa ndilopanga kwambiri ma cellulose ether padziko lonse lapansi. Panthawi imeneyi, zomangira nyumba kalasi cellulose ether wakhala makamaka m'dera. Shandong HEAD ndi bizinesi yotsogola pantchito zama cellulose ether ku China. Opanga ena akuluakulu apanyumba ndi Shandong RUITAI, Shandong HEAD, North TIANPU Chemical, YICHENG Cellulose, etc. Coating-grade, pharmaceutical and food grade cellulose ethers pakadali pano amalamulidwa ndi makampani akunja monga Dow, Ashland, Shin-Etsu, ndi Lotte. . Kuphatikiza pa Shandong HEAD ndi makampani ena omwe ali ndi mphamvu yoposa matani a 10,000, pali opanga ambiri ang'onoang'ono opanga ma cellulose ethers omwe ali ndi mphamvu ya matani 1,000. Zakudya zapamwamba komanso zopangira mankhwala.
5. Kulowetsa ndi kutumiza kunja kwa cellulose ether
Mu 2020, chifukwa cha kuchepa kwa kuchuluka kwa makampani akunja chifukwa cha mliri wakunja, kuchuluka kwa cellulose ether m'dziko langa kwawonetsa kukula mwachangu. Mu 2020, kutumiza kunja kwa cellulose ether kudzafika matani 77,272. Ngakhale kuti kuchuluka kwa kunja kwa cellulose ether ya dziko langa yakula mofulumira, zinthu zomwe zimatumizidwa kunja zimakhala zomangira ma cellulose ether, pamene kuchuluka kwa mankhwala ndi chakudya kalasi ya cellulose ether ndi yaying'ono kwambiri, ndipo mtengo wowonjezera wa zinthu zogulitsa kunja ndizochepa. Pakali pano, kuchuluka kwa katundu wa cellulose ether ya dziko langa ndi kuwirikiza kanayi voliyumu yochokera kunja, koma mtengo wotumizira kunja ndi wocheperapo kuwirikiza kawiri mtengo wamtengo wapatali. M'munda wa zinthu zapamwamba, njira yotumizira kunja kwa cellulose ether yapakhomo ikadali ndi malo ambiri opangira chitukuko.
