Ko mamiriro emusika wekunze nekunze kwemusika we non-ionic cellulose ether ari sei?

(1)Pfupiso yemusika wepasi rose we nonionic cellulose ether:

Kubva pamaonero ekugoverwa kwesimba rekugadzira pasi rose, 43% yehuwandu hwese hwepasi roseether ye celluloseKugadzirwa muna 2018 kwakabva kuAsia (China yakaita 79% yekugadzirwa kweAsia), Western Europe yakaita 36%, uye North America yakaita 8%. Kubva pamaonero ekudiwa kwe ether ye cellulose pasi rose, kushandiswa kwe ether ye cellulose pasi rose muna 2018 kunosvika matani angangoita mamiriyoni 1.1. Kubva muna 2018 kusvika 2023, kushandiswa kwe ether ye cellulose kuchakura paavhareji yegore negore ye2.9%.

Inenge hafu yekushandiswa kwese kwese kwe cellulose ether i ionic cellulose (inomiririrwa neCMC), iyo inonyanya kushandiswa mu sipo, zvinowedzera mafuta uye zvinowedzera chikafu; inenge chikamu chimwe muzvitatu i non-ionic methyl cellulose nezvinhu zvinobva mairi (zvinomiririrwa neHPMC), uye chikamu chimwe muzvitanhatu chasara ihydroxyethyl cellulose nezvimwe zvinobuda mairi pamwe chete nezvimwe zvinobuda mu cellulose ethers. Kukura kwekudiwa kwe non-ionic cellulose ethers kunonyanya kukonzerwa nekushandiswa kwezvinhu zvekuvaka, machira, chikafu, mishonga, uye makemikari ezuva nezuva. Kubva pamaonero ekugoverwa kwemusika wevatengi munharaunda, musika weAsia ndiwo musika unokurumidza kukura. Kubva muna 2014 kusvika 2019, huwandu hwegore negore hwekudiwa kwe cellulose ether muAsia hwakasvika 8.24%. Pakati pavo, kudiwa kukuru muAsia kunobva kuChina, kuchiverengera 23% yezvinodiwa pasi rose.

(2)Muchidimbu musika we ether wemumba usiri we ionic cellulose:

MuChina, ionic cellulose ethers inomiririrwa neCMCYakatangwa kare, ichigadzira nzira yekugadzira yakakura uye ine simba guru rekugadzira. Sekureva kwedata reIHS, vagadziri vekuChina vakatora inenge hafu yesimba rekugadzira zvigadzirwa zveCMC pasi rose. Kugadzirwa kwe non-ionic cellulose ether kwakatanga kunonoka munyika yangu, asi kukurumidza kwekugadzira kuri kukurumidza.

Zvichienderana nedata reChina Cellulose Industry Association, kugona kwekugadzira, kubuda uye kutengeswa kwe non-ionic cellulose ethers dzemabhizinesi emuno muChina kubva muna 2019 kusvika 2021 ndeizvi:

Mushure memakore ekuvandudzwa, musika weChina we non-ionic cellulose ether wafambira mberi zvikuru. Muna 2021, kugona kwekugadzira kwakagadzirwa kweHPMC yezvinhu zvekuvaka kuchasvika matani 117,600, kubuda kuchave matani 104,300, uye huwandu hwekutengesa huchava matani 97,500. Mabhenefiti makuru emaindasitiri uye nzvimbo dzekugara aita kuti pave nekutsiviwa kwemuno. Zvisinei, kune zvigadzirwa zveHEC, nekuda kwekutanga kweR&D nekugadzira munyika yangu, maitiro akaomarara ekugadzira uye zvipingamupinyi zvepamusoro zvetekinoroji, kugona kwekugadzira pari zvino, huwandu hwekugadzira uye hwekutengesa hwezvigadzirwa zveHEC zvemuno hushoma. Zvisinei, mumakore achangopfuura, sezvo mabhizinesi emuno achiramba achiwedzera mari mukutsvaga nekuvandudza, kuvandudza mwero wetekinoroji uye kusimudzira vatengi vari pasi, kugadzirwa nekutengesa kwakawedzera nekukurumidza. Sekureva kwedata kubva kuChina Cellulose Industry Association, muna 2021, mabhizinesi makuru emuno HEC (ari muhuwandu hwezviverengero zvemakambani, zvese zvinangwa) ane kugona kwekugadzira kwematani 19,000, kugona kwekugadzira kwematani 17,300, uye uwandu hwekutengesa hwematani 16,800. Pakati pawo, kugona kwekugadzira kwakawedzera ne72.73% gore negore zvichienzaniswa negore ra2020, kugona kwekugadzira kwakawedzera ne43.41% gore negore, uye uwandu hwekutengesa hwakawedzera ne40.60% gore negore.

Sekuwedzera, huwandu hwekutengesa hweHEC hunokanganiswa zvakanyanya nekudiwa kwemusika uri pasi. Senzvimbo inonyanya kukosha yeHEC, indasitiri yezvekuputira ine hukama hwakasimba neindasitiri yeHEC maererano nekubuda uye kugoverwa kwemusika. Kubva pamaonero ekugoverwa kwemusika, musika wezvekuputira unonyanya kupararira muJiangsu, Zhejiang neShanghai kuEast China, Guangdong kuSouth China, mahombekombe ekumaodzanyemba kwakadziva kumabvazuva, uye Sichuan kuSouthwest China. Pakati pavo, kubuda kwezvekuputira muJiangsu, Zhejiang, Shanghai neFujian kwaive neanenge 32%, uye uko kuSouth China neGuangdong kwaive neanenge 20%. 5 pamusoro apa. Musika wezvigadzirwa zveHEC wakanyanyawo kuJiangsu, Zhejiang, Shanghai, Guangdong neFujian. HEC parizvino inonyanya kushandiswa muzvekuputira zvekuvaka, asi yakakodzera marudzi ese ezvekuputira zvinobva mumvura maererano nehunhu hwayo hwechigadzirwa.

Muna 2021, huwandu hwese hwemapendi eChina anowanikwa pagore hunotarisirwa kunge hunosvika mamiriyoni makumi maviri nemashanu nemakumi masere nemaviri ematani, uye huwandu hwemapendi ekuvaka nemapendi eindasitiri huchava mamiriyoni manomwe nemakumi mashanu nerimwe ematani uye mamiriyoni gumi nemasere nemakumi matatu nerimwe ematani zvichiteerana. 6. Mapendi emvura parizvino anoita 90% yemapendi ekuvaka, uye anenge 25%, zvinofungidzirwa kuti kugadzirwa kwependi yemvura munyika yangu muna 2021 kuchava mamiriyoni gumi nerimwe nemakumi matatu nematatu nemakumi matanhatu nemashanu ematani. Mupfungwa, huwandu hweHEC hunowedzerwa pamapendi emvura i0.1% kusvika 0.5%, inoverengerwa paavhareji ye0.3%, tichifunga kuti pendi dzese dzemvura dzinoshandisa HEC sechiwedzerwa, kudiwa kwenyika kweHEC yemhando yependi ingava matani zviuru makumi matatu nezvina. Zvichienderana nehuwandu hwematani emamiriyoni 97.6 ekugadzira machira pasi rose muna 2020 (ayo machira ekuvaka anoita 58.20% uye machira eindasitiri anoita 41.80%), kudiwa kwepasi rose kweHEC yegiredhi remachira kunofungidzirwa kunge matani angangoita 184,000.

Mukupfupisa, pari zvino, musika weHEC yemhando ye coating yemakambani ekugadzira zvinhu muChina uchiri wakaderera, uye musika wemuno unonyanya kugarwa nevagadziri vepasi rose vanomiririrwa neAshland yeUnited States, uye kune nzvimbo yakakura yekutsiva zvinhu mudzimba. Nekuvandudzwa kwemhando yezvigadzirwa zveHEC zvemudzimba uye kuwedzera kwesimba rekugadzira, ichakwikwidzana nevagadziri vepasi rose mumunda wepasi unomiririrwa ne coating. Kutsiva zvinhu mudzimba uye makwikwi emusika wepasi rose zvichave mafambiro makuru ekuvandudza indasitiri iyi munguva yakati rebei mune ramangwana.

MHEC inonyanya kushandiswa mukugadzira zvinhu zvekuvaka. Inowanzo shandiswa mu cement mortar kuti ivandudze kuchengetedza kwayo mvura, kuwedzera nguva yekugadzika kwe cement mortar, kuderedza simba rayo rekutenderera uye simba rekumanikidza, uye kuwedzera simba rayo rekusunga. Nekuda kwe gel point yerudzi urwu rwechigadzirwa, hainyanyi kushandiswa mukugadzira, uye inonyanya kukwikwidzana neHPMC mukugadzira zvinhu zvekuvaka. MHEC ine gel point, asi yakakwira kupfuura HPMC, uye sezvo huwandu hwe hydroxy ethoxy huchiwedzera, gel point yayo inofamba ichienda kunzvimbo yekupisa kwakanyanya. Kana ikashandiswa mu mixed mortar, zvinobatsira kunonoka cement slurry pakupisa kwakanyanya. Bulk electrochemical reaction, kuwedzera mwero wekuchengetedza mvura uye simba re tensile bond re slurry nezvimwe zvinokanganisa.

Kukura kwemari inoshandiswa muindasitiri yekuvaka, nzvimbo yekuvaka dzimba, nzvimbo yakapedzwa, nzvimbo yekushongedza dzimba, nzvimbo yekugadzirisa dzimba dzekare uye shanduko dzadzo ndizvo zvinhu zvikuru zvinokanganisa kudiwa kweMHEC mumusika wemuno. Kubva muna 2021, nekuda kwedambudziko idzva rekorona pneumonia, mutemo wezvezvivakwa, uye njodzi dzemari dzemakambani ezvezvivakwa, kubudirira kweindasitiri yezvezvivakwa muChina kwaderera, asi indasitiri yezvezvivakwa ichiri indasitiri yakakosha mukusimudzira hupfumi hweChina. Pasi pemisimboti yese ye "kudzvinyirira", "kudzora kudiwa kusina musoro", "kudzikamisa mitengo yenyika, kudzikamisa mitengo yedzimba, uye kudzikamisa tarisiro", inosimbisa kutarisa pakugadzirisa chimiro chekugovera kwenguva yepakati nerefu, uku ichichengetedza kuenderera mberi, kugadzikana, uye kugara kwenguva refu kwemitemo yekutonga, uye kuvandudza musika wezvezvivakwa kwenguva refu. Nzira inoshanda yekutarisira kuona kuti musika wezvezvivakwa unogara kwenguva refu, wakasimba uye une hutano. Mune ramangwana, kusimudzira indasitiri yezvezvivakwa kuchava nekukura kwemhando yepamusoro nehunhu hwepamusoro uye kumhanya kwakaderera. Saka, kudzikira kuri kuita budiriro yeindasitiri yezvivakwa kuri kukonzerwa nekugadziriswa kweindasitiri zvishoma nezvishoma mukuita kwekuvandudza kwakanaka, uye indasitiri yezvivakwa ichiri nenzvimbo yekuvandudza mune ramangwana. Panguva imwe chete, zvichienderana ne "Chirongwa chemakore mashanu chegumi nemana cheNyika cheKubudirira kwehupfumi nemagariro evanhu uye 2035 Long-term Goal Outline", zvinokurudzirwa kushandura maitiro ekuvandudza maguta, kusanganisira kukurumidzisa kuvandudzwa kwemaguta, kushandura nekuvandudza nharaunda dzekare, mafekitori ekare, mabasa enzvimbo dzezvitoro dzakadai semabhuroko ekare nemisha yemaguta, uye kukurudzira kugadziriswa kwezvivakwa zvekare nezvimwe zvinangwa. Kuwedzera kwekudiwa kwezvinhu zvekuvaka mukugadzirisa dzimba dzekare inzira yakakosha yekuwedzera nzvimbo yemusika weMHEC mune ramangwana.

Zvichienderana nehuwandu hweChina Cellulose Industry Association, kubva muna 2019 kusvika 2021, kugadzirwa kweMHEC nemabhizinesi emuno kwaive matani 34,652, matani 34,150 uye matani 20,194 zvichiteerana, uye huwandu hwekutengesa hwaive matani 32,531, matani 33,570 uye matani 20,411 zvichiteerana, zvichiratidza kudzikira kukuru. Chikonzero chikuru ndechekutiMHECuye HPMC dzine mabasa akafanana, uye dzinonyanya kushandiswa pakuvaka zvinhu zvakaita sedhaka. Zvisinei, mutengo weMHEC nemutengo wekutengesa wakakwira kupfuura weHPMC. Mumamiriro ezvinhu ekukura kuri kuramba kuchienderera mberi kwehuwandu hwekugadzira HPMC munyika, kudiwa kwemusika weMHEC kwaderera. Muna 2019 Pakazosvika 2021, kuenzanisa pakati peMHEC neHPMC output, huwandu hwekutengesa, avhareji yemutengo, nezvimwewo ndekwekuti:
