Mamiriro emusika wepamba uye wekunze wenon-ionic cellulose ether ari sei?

(1)Mhedziso yemusika wepasi rose nonionic cellulose ether:

Kubva pamaonero epasi rose ekugadzira kugona kugovera, 43% yepasi rosecellulose etherkugadzirwa muna 2018 kwakabva kuAsia (China yakaverengera 79% yeAsia kugadzirwa), Western Europe yakaverengera makumi matatu nematanhatu%, uye North America yakaverengera 8%. Kubva pamaonero epasi rose cellulose ether kudiwa, iyo yepasi rose cellulose ether kushandiswa muna 2018 ingangoita 1.1 miriyoni matani. Kubva 2018 kusvika 2023, kushandiswa kwe cellulose ether kuchakura paavhareji yegore negore ye2,9%.

Inenge hafu yehuwandu hwepasi rose cellulose ether inoshandiswa ionic cellulose (inomiririrwa neCMC), iyo inonyanya kushandiswa mumishonga yekuchenesa, mafuta ekuwedzera uye zvokudya zvinowedzera; chinenge chikamu chimwe chete muzvitatu isiri-ionic methyl cellulose uye zvinobva mairi zvinhu (zvinomiririrwa neHPMC) Kukura kwekuda kweasiri-ionic cellulose ethers kunonyanya kufambiswa nekushandiswa muminda yezvivakwa zvekuvaka, machira, chikafu, mushonga, uye makemikari ezuva nezuva. Kubva pamaonero ekugoverwa kwedunhu kwemusika wevatengi, musika weAsia ndiyo inokurumidza kukurumidza musika. Kubva 2014 kusvika 2019, chiyero chekukura kwepagore chekudiwa kwe cellulose ether muAsia chakasvika 8.24%. Pakati pavo, iyo inonyanya kudiwa muAsia inobva kuChina, inoverengera 23% yezvese zvinodiwa pasi rose.

(2)Mhedziso yemusika wepasi-ionic cellulose ether musika:

MuChina, ionic cellulose ethers inomiririrwa neCMCyakagadziridzwa kare, ichigadzira hurongwa hwekugadzira hwakakura uye huwandu hukuru hwekugadzira. Zvinoenderana neiyo IHS data, vagadziri veChinese vakatora ingangoita hafu yepasi rose kugadzirwa kwezvinhu zvekutanga CMC zvigadzirwa. Kuvandudzwa kweiyo isiri-ionic cellulose ether yakatanga kunonoka munyika yangu, asi kukurumidza kwekusimudzira kunokurumidza.

Zvinoenderana nedatha yeChina Cellulose Indasitiri Association, huwandu hwekugadzira, kuburitsa uye kutengesa kweasiri-ionic cellulose ethers emabhizinesi epamba muChina kubva 2019 kusvika 2021 ndeaya:

Mushure memakore ebudiriro, musika weChina we-non-ionic cellulose ether wafambira mberi zvikuru. Muna 2021, iyo yakagadzirirwa kugadzirwa kwezvinhu zvekuvaka-giredhi HPMC ichasvika 117,600 matani, iyo inobuda ichave 104,300 matani, uye huwandu hwekutengesa huchave 97,500 matani. Huru hwemaindasitiri huyero uye mabhenefiti enzvimbo akave neruzivo rwekutsiva mudzimba. Nekudaro, kune HEC zvigadzirwa, nekuda kwekunonoka kutanga kweR&D uye kugadzirwa munyika yangu, yakaoma kugadzirwa maitiro uye yakakwira zvipingamupinyi zvehunyanzvi, huwandu hwazvino hwekugadzira, kugadzira uye kutengesa vhoriyamu yeHEC zvigadzirwa zvepamba zvishoma. Nekudaro, mumakore achangopfuura, sezvo mabhizinesi epamba ari kuramba achiwedzera mari mukutsvaga nekusimudzira, kuvandudza nhanho yetekinoroji uye nekushingaira kukudziridza vatengi vakaderera, kugadzira uye kutengesa kwakakura nekukurumidza. Zvinoenderana nedata kubva kuChina Cellulose Indasitiri Association, muna 2021, mabhizinesi makuru epamba HEC (anosanganisirwa muindasitiri yemubatanidzwa nhamba, zvese-chinangwa) ane akagadzirwa ekugadzira matani zviuru gumi nezvipfumbamwe, kubuda kwematani zviuru gumi nemazana matatu, uye huwandu hwekutengesa hwematani gumi nematanhatu. Pakati pavo, huwandu hwekugadzira hwakawedzera ne72.73% gore-ne-gore zvichienzaniswa ne2020, kubuda kwakawedzera ne43.41% gore-negore, uye huwandu hwekutengesa hwakawedzera ne40.60% gore negore.

Sekuwedzera, huwandu hwekutengesa hweHEC hunokanganiswa zvakanyanya nekudzika kwemusika kudiwa. Seyakanyanya kukosha nzvimbo yekushandisa yeHEC, iyo indasitiri yekupfekedza ine hukama hwakasimba hwakanaka neiyo HEC indasitiri maererano nekubuda uye kugoverwa kwemusika. Kubva pamaonero ekugoverwa kwemusika, musika weindastiri yekuputira unonyanya kugoverwa muJiangsu, Zhejiang neShanghai kuEast China, Guangdong muSouth China, kumaodzanyemba kwakadziva kumabvazuva kwemahombekombe, uye Sichuan muSouthwest China. Pakati pavo, iyo yekubikira yakabuda muJiangsu, Zhejiang, Shanghai neFujian yakaverengera 32%, uye iyo muSouth China neGuangdong yakaverengera makumi maviri muzana. 5 pamusoro. Musika weHEC zvigadzirwa zvakare wakanyanya kunangana muJiangsu, Zhejiang, Shanghai, Guangdong neFujian. HEC parizvino inonyanya kushandiswa mukugadzira machira, asi yakakodzera marudzi ese emvura-yakavakirwa machira maererano neayo chigadzirwa hunhu.

Muna 2021, kuburitswa kwepagore kwemachira eChina kunotarisirwa kunge kuri matani 25.82 miriyoni, uye kubuda kwemachira ekuvaka uye maindasitiri machira achave 7.51 miriyoni matani uye 18.31 miriyoni matani zvakateerana6. Mvura-based coatings pari zvino inotora chikamu che90% chezvivakwa zvekuvaka, uye nezve accounting ye25%, inofungidzirwa kuti nyika yangu inogadzirwa pendi yemvura muna 2021 ichave inosvika 11.3365 miriyoni matani. Nechepfungwa, huwandu hweHEC hwakawedzerwa kumvura-based paints ndeye 0.1% kusvika 0.5%, inoverengwa paavhareji ye0.3%, tichifunga kuti pendi dzose dzemvura dzinoshandisa HEC sekuwedzera, kudiwa kwenyika kwependi-giredhi HEC inenge 34,000 matani. Zvichienderana neyakajairwa pasi rose coating kugadzirwa kwematani 97.6 miriyoni muna 2020 (ayo ekuvaka anoisa 58.20% uye maindasitiri ejasi anoverengera 41.80%), kudiwa kwepasirese kwegiredhi rekuvhara HEC kunofungidzirwa kunge 184,000 matani.

Kupfupisa, pari zvino, chikamu chemusika chekuputira giredhi HEC yevagadziri vepamba muChina ichiri yakaderera, uye musika wepamusha unonyanya kugarwa nevagadziri vepasi rese vanomiririrwa neAshland yeUnited States, uye kune nzvimbo yakakura yekutsiva mudzimba. Nekuvandudzwa kwemhando yezvigadzirwa zvemumba HEC uye nekuwedzera kwehuwandu hwekugadzira, ichaenderera mberi kukwikwidza nevagadziri vepasirese mundima yezasi inomiririrwa nemachira. Kutsiva mudzimba uye kukwikwidza kwemusika wepasirese kuchava nzira huru yekusimudzira yeindastiri iyi mune imwe nguva yenguva mune ramangwana.

MHEC inonyanya kushandiswa mumunda wezvivakwa zvekuvaka. Inowanzoshandiswa mudhaka resimende kuvandudza kuchengetedza kwayo kwemvura, kurebesa nguva yekumisikidza simende, kuderedza simba rayo rekushanduka uye simba rekumanikidza, uye kuwedzera simba rayo rekubatanidza. Nekuda kweiyo gel point yerudzi urwu rwechigadzirwa, haishandiswe zvishoma mumunda wekupfeka, uye inonyanya kukwikwidza neHPMC mumunda wezvigadzirwa zvekuvaka. MHEC ine gel point, asi yakakwirira kupfuura HPMC, uye sezvo zvirimo zvehydroxy ethoxy zvichiwedzera, gel point yayo inoenda kunotungamira kupisa kwakanyanya. Kana ikashandiswa mudhaka rakasanganiswa, zvinobatsira kunonoka simende slurry pakupisa kwepamusoro Bulk electrochemical reaction, kuwedzera chiyero chekuchengetedza mvura uye kusimba kwechisungo cheslurry uye zvimwe zvinokonzeresa.

Huwandu hwekudyara hweindasitiri yekuvaka, nzvimbo yekuvaka zvivakwa, nzvimbo yakapera, nzvimbo yekushongedza imba, imba yekare yekugadziridza nzvimbo uye shanduko dzadzo ndizvo zvinhu zvikuru zvinokanganisa kudiwa kweMHEC mumusika wepamba. Kubva 2021, nekuda kwekukanganisa kweiyo korona itsva pneumonia denda, mutemo wezvivakwa, uye njodzi yekushomeka kwemakambani ezvivakwa, budiriro yeindasitiri yezvivakwa yeChina yakadzikira, asi indasitiri yezvivakwa ichiri indasitiri yakakosha yekusimudzira hupfumi hweChina. Pasi pemitemo yose ye "kudzvinyirirwa", "kudzivisa kudiwa kusina musoro", "kudzikamisa mitengo yevhu, kudzikamisa mitengo yeimba, uye kudzikamisa zvinotarisirwa", inosimbisa kuisa pfungwa pakugadzirisa maitiro ekugadzirisa kwepakati uye kwenguva refu, apo kuchengetedza kuenderera mberi, kugadzikana, uye kuwirirana kwemitemo yemitemo, nekuvandudza misika yenguva refu yezvivakwa. Inoshanda manejimendi nzira yekuve nechokwadi chenguva refu, yakagadzikana uye ine hutano kusimudzira kweiyo real estate musika. Mune ramangwana, kuvandudzwa kweindasitiri yezvivakwa kuchaita kunge iri yemhando yepamusoro kusimudzira nemhando yepamusoro uye yakaderera kumhanya. Naizvozvo, kuderera kwazvino mukubudirira kweindastiri yezvivakwa kunokonzerwa nekugadziriswa kwechikamu kweiyo indasitiri mukuita kwekupinda muhutano hwekusimudzira, uye indasitiri yezvivakwa ichine nzvimbo yekusimudzira mune ramangwana. Panguva imwecheteyo, maererano ne "14th Five-Year Plan for National Economic and Social Development uye 2035 Yenguva Yakareba Goal Outline", inokurudzirwa kushandura nzira yekuvandudzwa kwemaguta, kusanganisira kukurumidza kuvandudzwa kwemaguta, kushandura uye kusimudzira nharaunda dzekare, mafekitari ekare, mabasa ezvitoro zvakadai sezvivharo zvekare uye zvivakwa zvekare uye mamwe misha, uye kusimudzira zvivakwa zvemaguta uye mamwe misha. Kuwedzera kwekudiwa kwezvinhu zvekuvaka mukugadziridzwa kwedzimba dzekare zvakare kutungamira kwakakosha kwekuwedzera kweMHEC nzvimbo yemusika mune ramangwana.

Zvinoenderana nehuwandu hweChina Cellulose Indasitiri Association, kubva muna 2019 kusvika 2021, kuburitswa kweMHEC nemabhizinesi epamba kwaive 34,652 matani, 34,150 matani uye 20,194 matani zvichiteerana, uye huwandu hwekutengesa hwaive 32,531 matani, 33,531, zvichidzika zvichidzika, zvichidzika kusvika 33,520 zvichidzika. trend. Chikonzero chikuru ndechekutiMHECuye HPMC vane mabasa akafanana, uye anonyanya kushandiswa pakuvaka zvinhu zvakaita sedhaka. Nekudaro, mutengo uye mutengo wekutengesa weMHEC wakakwira kupfuura iwo weHPMC. Mumamiriro ezvinhu ekuenderera mberi kwekukura kwemumba HPMC yekugadzira huwandu, kudiwa kwemusika kweMHEC kwadzikira. Muna 2019 Pakazosvika 2021, kuenzanisa pakati peMHEC neHPMC kuburitsa, vhoriyamu yekutengesa, mutengo wepakati, nezvimwe zvakadaro:
