1. Muchidimbu Kusuma Cellulose Ether
Cellulose ether ishoko rinoshandiswa kune zvakasiyana-siyana zvakatorwa kubva kune zvakasikwa cellulose (yakanatswa donje uye huni pulp, etc.) Chigadzirwa chinoguma chinobva kuzasi kweselulosi. Mushure me etherification, cellulose inonyungudika mumvura, dilute alkali solution uye organic solvent, uye ine thermos plasticity. Kune marudzi mazhinji e-cellulose ethers, ayo anoshandiswa zvakanyanya mukuvaka, simende, pendi, mushonga, chikafu, peturu, makemikari ezuva nezuva, machira, kugadzira mapepa uye zvigadzirwa zvemagetsi uye mamwe maindasitiri. Zvinoenderana nehuwandu hwezvinotsiva, inogona kukamurwa kuita ether imwechete uye yakasanganiswa ether, uye zvinoenderana neionization, inogona kukamurwa kuita ionic cellulose ether uye isiri-ionic cellulose ether. Parizvino, ionic cellulose ether ionic zvigadzirwa zvine tekinoroji yekugadzira, kugadzirira kuri nyore, mutengo wakaderera, uye zvipingamupinyi zveindasitiri zvakaderera. Iwo anonyanya kushandiswa mukuwedzera kwechikafu, machira anobatsira, makemikari ezuva nezuva nemimwe minda, uye ndizvo zvigadzirwa zvikuru pamusika. chigadzirwa.
2. Iko kushandiswa kukuru uye basa re cellulose ether
Parizvino, mainstream cellulose ethers pasi rose iCMC, HPMC, MC, HEC, zvichingodaro. Pakati pawo, CMC ine chikamu chikuru chakabuda, inoverengera inenge hafu yezvakabuda pasi rose, ukuwo HPMC neMC zvese zvinotora chikamu che33% chepasi rose. kudiwa, uye HEC inoverengera inosvika makumi matatu muzana yezvinodiwa pasi rose. 13% yemusika. Kunyanya kukosha kwekupedzisira kushandiswa kwecarboxymethyl cellulose (CMC) ndeye detergent, inoverengera ingangoita 22% yemusika wepasi pemvura inodiwa, uye zvimwe zvigadzirwa zvinonyanya kushandiswa muminda yekuvaka, chikafu nemishonga.
Global Cellulose Ether Inoda Kuparara neChigadzirwa
3. Zvikumbiro zvepasi
Munguva yakapfuura, nekuda kwekukura kushoma kwekuda kwenyika yangu ye cellulose ether muminda yemazuva ese makemikari, mushonga, chikafu, machira, nezvimwewo, kudiwa kwe cellulose ether munyika yangu kwainyanya kuiswa mumunda wezvivakwa zvekuvaka. Kusvika nhasi, indasitiri yezvivakwa ichiri kuverengera 33% yenyika yangu cellulose ether inoda. %. Kudiwa kwenyika yangu cellulose ether mumunda wezvivakwa zvekuvaka kwave kuzara, uye kudiwa muminda yemazuva ese makemikari, mishonga, chikafu, machira, nezvimwe zviri kukura nekukurumidza nekuvandudzwa kwehunyanzvi hwekushandisa. Semuyenzaniso, mumakore achangopfuura, simira capsules ine cellulose ether sechinhu chikuru mbishi, uye nyama yekugadzira, chigadzirwa chiri kubuda chakagadzirwa ne cellulose ether, ine tarisiro yekuda kwakawanda uye nzvimbo yekukura.
Chiyero chezvakasiyana zvemusika wepasi peselulosi ether munyika yangu
Tichitora ndima yezvivakwa zvekuvaka semuenzaniso, cellulose ether ine yakanakisa zvivakwa zvakaita sekukora, kuchengetedza mvura, uye kunonoka. Naizvozvo, zvinhu zvekuvaka giredhi cellulose ether inoshandiswa zvakanyanya kuvandudza kugadzirwa kwedhaka rakagadzirwa-yakasanganiswa (kusanganisira yakanyorova-yakasanganiswa dhaka uye yakaoma-yakasanganiswa dhaka), PVC resin, nezvimwewo, latex pendi, putty, nezvimwewo, kusanganisira kuita kwe kuvaka zvinhu zvigadzirwa. Nekuda kwekuvandudzwa kwedanho remadhorobha renyika yangu, kukurumidza kusimukira kweindasitiri yezvivakwa zvekuvaka, kuenderera mberi kwekuvandudzwa kwedanho rekuvaka mechanization, uye kuwedzera kwekuchengetedza nharaunda zvinodiwa nevatengi zvezvinhu zvekuvaka zvakafambisa kudiwa kweasiri-ionic cellulose ethers. mumunda wezvigadzirwa zvekuvaka. Munguva yePurogiramu yeMakore Mashanu yechigumi nenhatu, nyika yangu yakakurumidzisa kugadziridzwa kwemisha yezvitangwena nedzimba dzakasakara, uye yakasimbisa kuvakwa kwezvivakwa zvemumaguta, kusanganisira kukurumidza kushandura misha yezvitangwena nemisha yemumaguta, zvichikurudzira kugadziridzwa kwakakwana kwedzimba dzekare dzekugara, dzakasakara dzimba dzekare uye dzisina kukwana seti Dzimba remodeling nezvimwe. Muhafu yekutanga ya2021, nzvimbo yezvivakwa zvekugara zvichangobva kutanga yaive 755.15 miriyoni square metres, kuwedzera kwe5. Nzvimbo yakapedzwa yeimba yaive 364.81 miriyoni square metres, kuwedzera kwe25.7%. Kudzoreredzwa kwenzvimbo yakapedzwa yezvivakwa kunofambisa kudiwa kwakabatana mumunda we cellulose ether zvekuvaka.
4. Musika wemakwikwi maitiro
Nyika yangu inogadzira zvakanyanya cellulose ether munyika. Panguva ino, zvekuvaka zvemukati giredhi cellulose ether yave yakanyatso kugariswa. Shandong HEAD ndiyo inotungamira bhizinesi mumunda we cellulose ether muChina. Mamwe makuru ekugadzira mudzimba anosanganisira Shandong RUITAI, Shandong HEAD, North TIANPU Chemical, YICHENG Cellulose, etc. Coating-giredhi, mishonga uye chikafu-giredhi cellulose ethers parizvino ari kunyanya kutorwa nemakambani ekunze akadai seDow, Ashland, Shin-Etsu, uye Lotte. . Pamusoro peShandong HEAD nemamwe makambani ane simba rinopfuura 10,000 matani, kune vakawanda vanogadzira madiki e-non-ionic cellulose ethers ane simba re 1,000 tons. Zvokudya zvepamusoro-soro uye zvigadzirwa zvegiredhi remishonga.
5. Kupinza uye kutumira kunze kwe cellulose ether
Muna 2020, nekuda kwekuderera kwehuwandu hwekugadzira kwemakambani ekunze nekuda kwedenda remhiri kwemakungwa, huwandu hwekutengesa kunze kwe cellulose ether munyika yangu hwakaratidza kukurumidza kukura. Muna 2020, kutengesa kunze kwe cellulose ether kuchasvika 77,272 matani. Kunyangwe huwandu hwekutengesa kunze kwenyika yecellulose ether yenyika yangu yakakura nekukurumidza, zvigadzirwa zvinotengeswa kunze kwenyika zvinonyanya kuvaka zvinhu cellulose ether, nepo huwandu hwekutumirwa kwemishonga uye chikafu chegiredhi cellulose ether idiki kwazvo, uye kukosha kwakawedzerwa kwezvigadzirwa kunze kwenyika kwakaderera. Parizvino, huwandu hwekunze kwenyika hweselulosi ether yenyika yangu hwakapeta kana huwandu hwekuunza kunze kwenyika, asi kukosha kwekutumirwa kunze kwenyika kuri pasi pekaviri kukosha kwekuunza. Mumunda wezvigadzirwa zvepamusoro-soro, iyo yekutsinhanisa kunze kwekunze kwemukati cellulose ether ichine nzvimbo yakawanda yekusimudzira.
