Icyiciro cyo kubaka MHEC

Urwego rwo kubaka MHEC

Icyiciro cyo kubaka MHEC M.Ethyl HydroxyethylCelluloseni impumuro nziza, idafite uburyohe, idafite uburozi bwifu yifu ishobora gushonga mumazi akonje kugirango ibe igisubizo kibonerana. Ifite ibiranga kubyimba, guhuza, gutatanya, emulisation, gukora firime, guhagarikwa, adsorption, gelation, ibikorwa byubutaka, kugumana ubushuhe hamwe na colloid ikingira. Kubera ko igisubizo cyamazi gifite imikorere igaragara hejuru, irashobora gukoreshwa nkumuti urinda colloidal, emulifier na dispersant. Icyiciro cyo kubaka MHEC methyl Hydroxyethylcellulose igisubizo cyamazi gifite hydrophilicity kandi nikintu cyiza cyo kubika amazi. Hydroxyethyl methyl selulose irimo amatsinda ya hydroxyethyl, bityo ikaba ifite ubushobozi bwiza bwo kurwanya ibibyimba, guhagarara neza kwijimye no kurwanya indwara ya mildew mugihe cyo kubika igihe kirekire.

Imiterere yumubiri nubumashini:

Kugaragara: MHEC ni umweru cyangwa hafi ya fibrous yera cyangwa ifu ya granular; impumuro nziza.

Gukemura: MHEC irashobora gushonga mumazi akonje namazi ashyushye, L moderi irashobora gushonga mumazi akonje gusa, MHEC ntishobora gushonga mumashanyarazi menshi. Nyuma yo kuvura hejuru, MHEC ikwirakwira mumazi akonje nta agglomeration, kandi igashonga buhoro, ariko irashobora gushonga vuba muguhindura agaciro ka PH ya 8 ~ 10.

PH itajegajega: Ubukonje burahinduka gake murwego rwa 2 ~ 12, kandi ubwiza bugabanuka kurenza iyi ntera.

Granularity: igipimo cya mesh 40 ≥99% 80 igipimo cya mesh 100%.

Ubucucike bugaragara: 0.30-0.60g / cm3.

Gusaba 

Urwego rwo kubaka MHEC methyl Hydroxyethyl selulose irashobora gukoreshwa nka colloid ikingira, emulisiferi kandi ikwirakwiza bitewe nubuso bwayo bukora mubisubizo byamazi. Ingero zikoreshwa ni izi zikurikira:

1. Ingaruka za methylhydroxyethylcellulose kumikorere ya sima. Kubaka urwego MHEC methylHydroxyethylcellulose ni ifu yera itagira impumuro nziza, itaryoshye, idafite uburozi ishobora gushonga mumazi akonje kugirango bibe igisubizo kiboneye kibonerana. Ifite ibiranga kubyimba, guhuza, gutatanya, emulisation, gukora firime, guhagarikwa, adsorption, gelation, ibikorwa byubutaka, kugumana ubushuhe hamwe na colloid ikingira. Kubera ko igisubizo cyamazi gifite imikorere igaragara hejuru, irashobora gukoreshwa nka colloid ikingira, emulisiferi na dispersant. Kubaka icyiciro cya MHEC methyl Hydroxyethyl selulose yumuti wamazi ufite hydrophilique nziza kandi nikintu cyiza cyo kubika amazi.
2. Tegura irangi ryubutabazi hamwe nubworoherane buhanitse, bikozwe mubice bikurikira kuburemere bwibikoresho fatizo: 150-200g y'amazi ya deionion; 60-70g ya emulion yuzuye ya acrylic; 550-650g ya calcium iremereye; 70-90g ya talc; 30-40g ya methyl selulose yumuti wamazi; 10-20g yumuti wamazi wa lignocellulose; 4-6g yimfashanyo ikora firime; 1.5-2.5g ya antiseptic fungicide; 1.8-2.2g yo gutatanya; 1.8-2.2g yumukozi woza; Thickener 3.5-4.5g; Ethylene glycol 9-11g; icyiciro cyubwubatsi MHEC igisubizo cyamazi gikozwe muri 2-4% Icyiciro cyinyubako MHEC yashonga mumazi; iselileigisubizo cyamazi gikozwe muri 1 -3%selilebikozwe no gushonga mumazi.

Uburyo bwo gutanga umusaruroIcyiciro cyo kubaka MHEC？

Uwitekaumusarurouburyo bwo kubaka icyiciro cya MHEC methyl hydroxyethyl selulose ni uko ipamba itunganijwe ikoreshwa nkibikoresho fatizo naho okiside ya Ethylene ikoreshwa nkibikoresho bya etherifing kugirango utegure icyiciro cya MHEC. Ibikoresho fatizo byo gutegura icyiciro cyo kubaka MHEC gitegurwa mubice byuburemere: ibice 700-800 bya toluene na isopropanol bivanze nkibishishwa, ibice 30-40 byamazi, ibice 70-80 bya sodium hydroxide, 80-85 by ipamba nziza, impeta ibice 20-28 bya oxyethane, ibice 80-90 bya methyl chloride, ibice 16-19 bya acide glacial acetique; intambwe zihariye nizi zikurikira:

Mu ntambwe yambere, ongeramo imvange ya toluene na isopropanol, amazi, na hydroxide ya sodium muri keteti ya reaction, uzamure ubushyuhe kuri 60-80 ° C, hanyuma ubigumane muminota 20-40;

Intambwe ya kabiri, alkalisation: gukonjesha ibikoresho byavuzwe haruguru kuri 30-50 ° C, ongeramo ipamba inoze, utere hamwe nuruvange rwa toluene na isopropanol, wimure kuri 0.006Mpa, wuzuze azote kubasimbuye 3, hanyuma ukore alkalis nyuma yo kuyisimbuza Ibihe bya alkalisation ni nkibi bikurikira: igihe cyo guswera ni amasaha 2, naho ubushyuhe bwa alkalisation ni 30 ℃-50 ℃;

Intambwe ya gatatu, etherification: nyuma ya alkalisation, reaction yimurwa kugeza 0.05～0.07MPa, okiside ya Ethylene na methyl chloride yongeweho kandi ibikwa kuri 30～Iminota 50; icyiciro cya mbere cya etherification: 40～60 ℃, 1.0～Amasaha 2.0, igitutu kiyobowe hagati ya 0.15-0.3Mpa; icyiciro cya kabiri cya etherification: 60～90 ℃, 2.0～Amasaha 2.5, igitutu kiyobowe hagati ya 0.4-0.8Mpa;

Intambwe ya kane, kutabogama: ongeramo metero ya glacial acetike ya acide mbere ya desolventizer, kanda mubikoresho bya etherified kugirango bitabogamye, byongere ubushyuhe kuri 75～80 ℃ yo gusenya, ubushyuhe buzamuka bugere kuri 102 and, naho agaciro ka pH kazaba 68. Iyo gusenya birangiye; kuzuza isafuriya ya desolvation n'amazi ya robine yatunganijwe nigikoresho cya osmose ihindagurika kuri 90 ℃～100 ℃;

Intambwe ya gatanu, gukaraba centrifugal: ibikoresho byo muntambwe ya kane byashyizwe hamwe na centrifuge ya horizontal, hanyuma ibikoresho bitandukanijwe byimurirwa mu isafuriya yo gukaraba yuzuyemo amazi ashyushye mbere yo koza ibikoresho;

Intambwe ya gatandatu, yumisha centrifugal: ibikoresho byogejwe bijyanwa mumashanyarazi binyuze muri horizontal centrifuge ya horizontal, ibikoresho byumye kuri 150-170 ° C, nibikoresho byumye bikajanjagurwa bikapakirwa.

Ugereranije na selile isanzwe ya selile ikora, ubuuburyo bwo kubyaza umusaruroikoresha okiside ya Ethylene nkumukozi wa etherifyinga kugirango ategure ibyiciro byubaka MHEC methyl hydroxyethyl selulose, kandi kubera ko irimo amatsinda ya hydroxyethyl, ifite ubushobozi bwiza bwa antifungal. Guhagarara neza kwijimye no kurwanya mildew mugihe cyo kubika igihe kirekire. Irashobora gusimbuza izindi selile.

Building urwego MHECni selile ya ether ikomoka,Cellulose ether ni polymer nziza yimiti ifite imiti myinshi ikoreshwa muri polymer naturelose isanzwe ivura imiti. Kuva nitrate ya selulose na selulose acetate yakozwe mu kinyejana cya 19, abahanga mu bya shimi bakoze urutonde rwinshi rukomoka kuri selile ikomoka kuri selile. Imirima mishya ikoreshwa ihora ivumburwa kandi inganda nyinshi zirimo. Ibicuruzwa bya selile ya selile nka sodium carboxymethyl selulose (CMC), Ethyl selulose (EC), hydroxyethyl selulose (HEC), hydroxypropyl selulose (HPC), methyl hydroxyethyl selulose (MHEC) Na methyl hydroxypropyl selulose (MHPC) nibindi bya selile. "Inganda monosodium glutamate" hamwe nicyiciro cyo kubaka MHEC cyabaye kinini ikoreshwa muri tile yometseho, yumye yumye, sima na gypsumu nibindi.
