1. Ubu umusaruro wimbere mu gihugu hamwe nibisabwa na hydroxyethyl selulose
1.1 Kumenyekanisha ibicuruzwa
Hydroxyethyl selulose (yitwa hydroxyethyl selulose) ni hydroxyalkyl selulose ikomeye, yateguwe neza na Hubert mu 1920 kandi ni na eferi ya elegitoronike ikora amazi kandi ifite umusaruro mwinshi ku isi.Gusa iyi nini nini kandi yihuta cyane itera imbere ya selile nyuma ya CMC na HPMC.Hydroxyethyl selulose ni polymer idafite amazi ya elegitoronike yabonetse hamwe nuruhererekane rwo gutunganya imiti itunganijwe neza (cyangwa ibiti byimbaho).Nibintu byera, bidafite impumuro nziza, ifu idafite uburyohe cyangwa ibintu bikomeye.
1.2 Ubushobozi bwo gukora ku isi nibisabwa
Kugeza ubu, amasosiyete manini ya hydroxyethyl selulose ku isi yibanda mu bihugu by'amahanga.Muri byo, ibigo byinshi nka Hercules na Dow muri Amerika bifite ubushobozi bukomeye bwo kubyaza umusaruro, bikurikirwa n'Ubwongereza, Ubuyapani, Ubuholandi, Ubudage n'Uburusiya.Biteganijwe ko umusaruro wa hydroxyethyl selulose ku isi mu 2013 uzaba toni 160.000, hamwe n’ikigereranyo cyo kuzamuka kw’umwaka ku kigero cya 2.7%.
1.3 Ubushinwa bukora umusaruro nibisabwa
Kugeza ubu, ubushobozi bw’ibarurishamibare mu gihugu bwa hydroxyethyl selulose ni toni 13.000.Usibye abahinguzi bake, ahasigaye ahanini bahinduwe kandi bahujwe nibicuruzwa, ntabwo hydroxyethyl selulose muburyo nyabwo.Bahura cyane nisoko ryo mucyiciro cya gatatu.Hydroxyethyl selulose yimbere mu gihugu Umusaruro wa selile fatizo uri munsi ya toni 3.000 kumwaka, kandi ubushobozi bwisoko ryimbere mu gihugu ni toni 10,000 kumwaka, muribyo birenga 70% bitumizwa hanze cyangwa bitangwa ninganda zatewe inkunga n’amahanga.Inganda zingenzi z’amahanga ni Yakuolong Company, Dow Company, Klein Company, AkzoNobel Company;uruganda rwa hydroxyethyl selulose rukora ibicuruzwa harimo cyane cyane Cellulose y'Amajyaruguru, Shandong Yinying, Yixing Hongbo, Wuxi Sanyou, Hubei Xiangtai, Yangzhou Zhiwei, nibindi. umugabane utwarwa nibicuruzwa byo hanze.Igice cyamasoko yimyenda, resin na wino.Hariho itandukaniro rigaragara hagati yibicuruzwa byimbere mu gihugu n’amahanga.Isoko ryo mu rwego rwo hejuru mu gihugu rya hydroxyethyl ryihariwe cyane n’ibicuruzwa byo hanze, kandi ibicuruzwa byo mu gihugu ahanini biri ku isoko ryo hagati no hasi.Koresha hamwe kugirango ugabanye ingaruka.
Isoko rya hydroxyethyl selulose rishingiye ku karere, Pearl River Delta (Ubushinwa bw'Amajyepfo) niyambere;hakurikiraho umugezi wa Delta wa Yangtze (Ubushinwa bw'Uburasirazuba);icya gatatu, Uburengerazuba bw'Amajyepfo n'Ubushinwa;imyenda 12 ya mbere ya latx Usibye Nippon Paint na Zijinhua, ifite icyicaro i Shanghai, ahasigaye cyane cyane mu karere k'Ubushinwa.Ikwirakwizwa ry’inganda zikora imiti buri munsi naryo cyane cyane mubushinwa bwamajyepfo no mubushinwa.
Urebye ku bushobozi bwo kubyara umusaruro, irangi ni inganda zikoresha cyane hydroxyethyl selulose, zikurikirwa n’imiti ya buri munsi, icya gatatu, amavuta, n’inganda zikoresha bike cyane.
Gutanga mu gihugu no gukenera hydroxyethyl selulose: muri rusange gutanga no gukenera kuringaniza, hydroxyethyl selulose yo mu rwego rwo hejuru ntishobora kubikwa gato, hamwe na hydroxyethyl selile yo mu rwego rwo hasi yo mu rwego rwo hasi, hydroxyethyl selulose yo mu rwego rwa peteroli, hamwe na hydroxyethyl selulose Cellulose itangwa ahanini na imishinga yo mu gihugu.70% by'isoko rusange rya hydroxyethyl selile yo mu gihugu itwarwa na hydroxyethyl selile yo mu mahanga yo mu rwego rwo hejuru.
Ibyiza no gukoresha 2-hydroxyethyl selulose
2.1 Ibyiza bya hydroxyethyl selile
Ibintu nyamukuru biranga hydroxyethyl selulose ni uko ibora mumazi akonje namazi ashyushye, kandi ikaba idafite imiterere.Ifite intera nini yo gusimbuza, kwikemurira no kwiyegeranya.imvura.Hydroxyethyl selulose yumuti irashobora gukora firime ibonerana, kandi ifite ibiranga ubwoko butari ionic budahuza na ion kandi bufite ubwuzuzanye bwiza.
TemperatureUbushyuhe bwo hejuru hamwe no gukomera kwamazi: Ugereranije na methyl selulose (MC), iboneka gusa mumazi akonje, hydroxyethyl selulose irashobora gushonga mumazi ashyushye cyangwa mumazi akonje.Urwego runini rwo gukemuka no kuranga viscosity, hamwe na gelasi idafite ubushyuhe;
Resistance Kurwanya umunyu: Bitewe nubwoko butari ionic, irashobora kubana nizindi polymers zishonga amazi, surfactants hamwe nu munyu mugari.Kubwibyo, ugereranije na ionic carboxymethyl selulose (CMC), hydroxyethyl selile ifite imbaraga zo kurwanya umunyu.
Ret Kugumana amazi, kuringaniza, gukora firime: ubushobozi bwayo bwo gufata amazi bwikubye kabiri methyl selulose, hamwe nogutunganya neza no gukora firime nziza, kugabanya amazi, kugabanuka nabi, guhuza ibitsina bikingira.
2.2 Gukoresha hydroxyethyl selulose
Hydroxyethyl selulose nigicuruzwa kitari ionic cyamazi ya elegitoronike ya ether, ikoreshwa cyane mububiko bwububiko, peteroli, polymer polymerisation, ubuvuzi, gukoresha burimunsi, impapuro na wino, imyenda, ububumbyi, ubwubatsi, ubuhinzi nizindi nganda.Ifite imirimo yo kubyimba, guhuza, kwigana, gutatanya no gutuza, kandi irashobora kugumana amazi, gukora firime no gutanga ingaruka zo gukingira.Irashobora gushonga byoroshye mumazi akonje namazi ashyushye, kandi irashobora gutanga igisubizo hamwe nubwinshi bwubwiza.Imwe muma selile yihuta.
1) Irangi rya Latex
Hydroxyethyl selulose niyo ikoreshwa cyane mubyimbye muri latex.Usibye kubyimba latx yatwikiriye, irashobora kandi kwigana, gutatanya, gutuza no kugumana amazi.Irangwa ningaruka zidasanzwe zibyibushye, iterambere ryiza ryamabara, imitungo ikora firime hamwe nububiko buhamye.Hydroxyethyl selile ni inkomoko ya ionic selulose ishobora gukoreshwa muburyo bugari bwa pH.Ifite guhuza neza nibindi bikoresho mubice (nka pigment, inyongeramusaruro, uwuzuza umunyu).Ipitingi yuzuye hamwe na hydroxyethyl selulose ifite rheologiya nziza kubiciro bitandukanye byogosha kandi ni pseudoplastique.Uburyo bwubwubatsi nko gukaraba, gusiga uruziga, no gutera.Ubwubatsi bwiza, ntabwo byoroshye gutonyanga, kugabanuka no kumeneka, no kuringaniza neza.
