Icyiciro cy'inyubako MHEC

Icyiciro cy'inyubako MHEC Methyl HydroxyethylCelliloseNi ifu yera idahumura, idasembuye kandi idahumanya ishobora gushonga mu mazi akonje kugira ngo ikore umuti ubonerana. Ifite imiterere yo gukomera, gufatana, gukwirakwira, gukurura, gukora firime, kuyihagarika, kuyishyira mu kirere, kuyisiga, kuyigabanya, gukora ku buso, kubika amazi no kuyirinda. Kubera ko umuti w'amazi ufite imikorere ikora ku buso, ushobora gukoreshwa nk'umuti urinda colloidal, emulsifier na dispersant. Umuti w'amazi wa MHEC wo mu rwego rwo kubaka ufite ubushobozi bwo kuvura amazi kandi ni umuti urinda amazi neza. Hydroxyethyl methyl cellulose irimo amatsinda ya hydroxyethyl, bityo ifite ubushobozi bwiza bwo kurwanya imyumbati, kudahinduka neza kw'ubushyuhe no kurwanya ubwivumbure mu gihe kirekire.

Imiterere y'umubiri n'imiti:

Ishusho: MHEC ni ifu y'umweru cyangwa hafi yera ifite uduce duto cyangwa ingano; nta mpumuro igira.

Gushonga: MHEC ishobora gushonga mu mazi akonje n'amazi ashyushye, L model ishobora gushonga mu mazi akonje gusa, MHEC ntishobora gushonga mu bintu byinshi bishongesha mu binyabutabire. Nyuma yo gutunganya ubuso, MHEC ikwirakwira mu mazi akonje nta guhurirana, kandi ishonga buhoro buhoro, ariko ishobora gushonga vuba iyo ihinduye agaciro kayo ka PH ka 8 ~ 10.

Ubudahangarwa bwa PH: Ubudahangarwa buhinduka gato mu rugero rwa 2 ~ 12, kandi ubudahangarwa bugabanuka birenze urwo rugero.

Ubunini: Igipimo cyo gutsinda cya mesh 40 ≥99% Igipimo cyo gutsinda cya mesh 80 100%.

Ubucucike bugaragara: 0.30-0.60g/cm3.

Porogaramu 

Ingano y'inyubako ya MHEC methyl Hydroxyethyl cellulose ishobora gukoreshwa nk'ikingira, emulsifier na dispersant bitewe n'imikorere yayo mu gisubizo cy'amazi. Ingero z'ikoreshwa ryayo ni izi zikurikira:

1. Ingaruka za methylhydroxyethylcellulose ku mikorere ya sima. Hydroxyethylcellulose yo mu rwego rw'ubwubatsi ni ifu yera idafite impumuro, uburyohe, kandi idahumanya ishobora gushonga mu mazi akonje kugira ngo ikore umuti ubonerana. Ifite imiterere yo gukomera, gufatana, gukwirakwira, emulsification, gukora firime, gusunika, kunyuzamo amazi, kwegeranya, gukora ku buso, kubika amazi no kurinda colloid. Kubera ko umuti w'amazi ufite imikorere ikora ku buso, ushobora gukoreshwa nk'umuti urinda colloid, emulsifier na dispersant. Umuti w'amazi wa MHEC yo mu rwego rw'ubwubatsi wa Hydroxyethyl cellulose ufite ubushobozi bwo gufata amazi neza kandi ni umuti mwiza wo kubika amazi.
2. Tegura irangi ryoroshye cyane, rikozwe mu bice bikurikira hakurikijwe uburemere bw'ibikoresho fatizo: 150-200g by'amazi yakuwemo ioni; 60-70g by'umusemburo wa acrylic; 550-650g by'umusemburo mwinshi wa kalisiyumu; 70-90g by'umusemburo wa talc; 30-40g by'umusemburo wa methyl cellulose; 10-20g by'umusemburo w'amazi wa lignocellulose; 4-6g by'ibikoresho bikora filime; 1.5-2.5g by'umusemburo urwanya udukoko; 1.8-2.2g by'umusemburo ugabanya ubukana; 1.8-2.2g by'umusemburo ugabanya ubukana; 1.8-2.2g by'umusemburo ugabanya ubukana; 3.5-4.5g; ethylene glycol 9-11g; umusemburo w'amazi wa MHEC wo mu rwego rw'ubwubatsi ukozwe muri 2-4% by'umusemburo wa MHEC uvanze mu mazi;fibre ya seluloseumuti w'amazi ukozwe muri 1 -3%fibre ya selulosebikorwa binyuze mu gushonga mu mazi.

Uburyo bwo gukoraInzu MHEC y'icyiciro cy'inyubako？

ItsindaumusaruroUburyo bwo kubaka MHEC methyl hydroxyethyl cellulose ni uko ipamba itunganyijwe ikoreshwa nk'ibikoresho fatizo naho ethylene oxide igakoreshwa nk'ikintu gitanga ubushyuhe mu gutegura MHEC yo kubaka. Ibikoresho fatizo byo gutegura MHEC yo kubaka bitegurwa mu bice hakurikijwe uburemere: ibice 700-800 bya toluene na isopropanol nk'umusemburo, ibice 30-40 by'amazi, ibice 70-80 bya sodium hydroxide, ibice 80-85 by'ipamba itunganyijwe, impeta ibice 20-28 bya oxythane, ibice 80-90 bya methyl chloride, ibice 16-19 bya aside glacial acetic; intambwe zihariye ni izi zikurikira:

Mu ntambwe ya mbere, shyiramo uruvange rwa toluene na isopropanol, amazi, na sodiyumu hidroksidi mu gikoresho cyo gupima, wongere ubushyuhe kuri dogere selisiyusi 60-80, hanyuma ubigumishe mu gihe cy'iminota 20-40;

Intambwe ya kabiri, gukonjesha ibikoresho byavuzwe haruguru kugeza kuri 30-50°C, ongeramo ipamba itunganyijwe, ushyiremo uruvange rwa toluene na isopropanol, ushyiremo 0.006Mpa, wuzuze azote inshuro 3, hanyuma ukoreshe alkali nyuma yo kuyihindura. Imiterere y'ikoreshwa ry ...-50°C;

Intambwe ya gatatu, eteri: nyuma yo gushyiramo alkali, reactor ijyanwa kuri 0.05～0.07MPa, ethylene oxide na methyl chloride byongerwaho kandi bikabikwa mu gihe cy'iminota 30～Iminota 50; icyiciro cya mbere cyo gupima ubushyuhe: 40～Ubushyuhe bwa 60°C, 1.0～Amasaha 2.0, igitutu kigenzurwa hagati ya 0.15-0.3Mpa; icyiciro cya kabiri cyo gupima ubushyuhe: 60～90℃, 2.0～Mu masaha 2.5, igitutu kigenzurwa hagati ya 0.4-0.8Mpa;

Intambwe ya kane, gutandukanya: ongeramo aside glacial asetic mbere y'igihe kuri desolventizer, kanda mu bikoresho bya etherized kugira ngo bigabanya ubushyuhe, wongere ubushyuhe kuri dogere 75～80°C kugira ngo habeho ubushyuhe buzamuka bugere kuri 102°C, kandi agaciro ka pH kazaba 68. Iyo ubushyuhe burangiye, uzuza amazi yo mu isafuriya yo kubukuraho amazi yavuwe n'igikoresho gisubiza inyuma ku bushyuhe bwa 90°C.～100°C;

Intambwe ya gatanu, gukaraba hakoreshejwe centrifuge: ibikoresho biri mu ntambwe ya kane bishyirwa muri centrifuge hakoreshejwe screw screw itambitse, hanyuma ibikoresho byatandukanyijwe bishyirwa mu isafuriya yuzuyemo amazi ashyushye mbere yo koza ibikoresho;

Intambwe ya gatandatu, ni ukumisha hakoreshejwe centrifuge: ibikoresho byogejwe bijyanwa mu cyuma cyumisha hakoreshejwe screw centrifuge itambitse, ibikoresho bikuma kuri 150-170°C, hanyuma ibikoresho byumye bigasenywa bigapfunyikwa.

Ugereranyije n'ikoranabuhanga risanzweho ryo gukora eteri ya cellulose, ubuuburyo bwo gukoraIkoresha ethylene oxide nk'ikintu gitanga ubushyuhe mu gutegura selulosi ya MHEC yo mu rwego rwo kubaka, kandi kubera ko irimo amatsinda ya hydroxyethyl, ifite ubushobozi bwiza bwo kurwanya indwara. Irakomera neza kandi irarwanya indwara mu gihe kibitswe igihe kirekire. Ishobora gusimbura izindi ether za selulosi.

Burwego rwo kubaka MHECni ibikomoka kuri eteri ya selulose,Cellulose ether ni ibikoresho bya polymer byiza bifite uburyo bwinshi bwo gukoresha biva muri polymer cellulose karemano binyuze mu kuvura imiti. Kuva aho nitrati ya cellulose na acetate ya cellulose byakorewe mu kinyejana cya 19, abahanga mu bya shimi bakoze urukurikirane rw'ibintu byinshi biva muri cellulose bya ether za cellulose. Inzego nshya zikoreshwa zihora zivumburwa kandi hari inganda nyinshi zibigiramo uruhare. Ibicuruzwa bya ether bya cellulose nka sodium carboxymethyl cellulose (CMC), ethyl cellulose (EC), hydroxyethyl cellulose (HEC), hydroxypropyl cellulose (HPC), methyl hydroxyethyl cellulose (MHEC) Kandi methyl hydroxypropyl cellulose (MHPC) n'izindi ether za cellulose zizwi nka "monosodium glutamate y'inganda" kandi MHEC yo mu rwego rwo kubaka yakoreshejwe cyane mu gufunga amatafari, mortier yumye, sima na plaster ya gypsum n'ibindi.
