Nigute methyl hydroxyyeryl selile yateguwe?

Amavu n'amavuko

Ubugari bwa selile ni polymer yakoreshejwe cyane yimiti ikozwe muri polymer karemano yubugari binyuze mubuvuzi. Nyuma yo gukora sitrate ya selile na selile yashyizeho urukurikirane rwa selile, kandi imirima mishya yavumbuwe ubudahwema, imaze gukoreshwa mu bikorwa byinshi mu nganda. Ubugari bwa Cellus Bicuruzwa nka sodium carboxymethyl selile ya selile (ec), hptroxyIcyubahiro Nk'inganda za Monosodium "kandi byakoreshwaga cyane mu gukinisho bya peteroli, kubaka, aho bihurira, ibiryo, imiti n'imiti ya buri munsi.

Hydroxyyeryy Methyl Methyl Medoulose (mHPC) ni ifu yera itagira impumuro nziza ishobora gushonga mumazi akonje kugirango akore igisubizo gisobanutse. Ifite ibiranga ibiranga, guhuza, gutatana, kurengana, gushiraho film, guhagarikwa, gukomera, gukomeza ubushuhe no kurinda ubushuhe no kurinda ubushuhe no kurengera colloid no kurinda ubushuhe no kurengera colloid. Bitewe nubuso bwibikorwa byigisubizo cyamazebwe, birashobora gukoreshwa nkabakozi ba colloidal, emalifier no gutabarwa. Hydroxyyethyy Methylcellus igisubizo cy'amazi afite hydrofili nziza kandi ni ushinzwe kugumana amazi meza. Kuberako hydroxyyerthyl methylcellse irimo amatsinda ya hydroxyerthyl, ifite ubushobozi bwiza bwo kurwanya mildew, umutekano mwiza wa vildew, ubukungu bwifashe neza kandi bwo kurwanya indwara yoroheje mugihe cyo kubika igihe kirekire.

Hydroxyyeryy MethylcellllAlose (HEMC) yateguwe no kumenyekanisha abasimbuye Ethylene (MS 0.4) muri Methylcellseliulose (MC), kandi kurwanya umunyu biruta ibyo polymers itazwi. Ubushyuhe bwa Gelalelcellsellse nacyo kiri hejuru yubwa MC.

Imiterere

Ibiranga

Ibiranga nyamukuru bya hydroxyyethyl methylcellse (hemc) ni:

1.. Hemc irashobora gushonga mumazi akonje. Ubushake bwayo bukomeye bugenwa gusa na viscosiya. Kukesha agaciro biratandukanye na viscosiya. Kumanura viscosiya, niko kwitonda.

2. Kurwanya Umunyu: Ibicuruzwa HemC ni elegisi itari iolyleleadtes, nuko birahagaze neza mugihe cyamashanyarazi cyangwa kongerera amashanyarazi bishobora kubaho, ariko kongera amashanyarazi mu buryo bwa electrolytes birashobora gutera ingwate.

3. Igikorwa cyo hejuru: Bitewe nimikorere yubuso bwibisubizo bitangaje, birashobora gukoreshwa nkabakozi ba colloidal, emalifier no gutabarwa.

4. Gel

5. Impeta ya Metabolic na Odor nkeya nimpumuro: Hemc ikoreshwa cyane mubiryo nubuvuzi kuko itazagira ubwenge kandi ifite impumuro nke nimpumuro nziza.

6. Kurwanya Lowew: Hemc afite imbaraga nziza zo muriboherwa no gushishoza neza mugihe cyo kubika igihe kirekire.

7..

Gusaba

Hydroxyyeryl Methylcellsellse irashobora gukoreshwa nkabakozi ba colloidal, emalifier no gutatanya kubera imikorere-ikora mu gisubizo gikora. Ingero zayo zisaba ni izi zikurikira:

1. Ingaruka za HydroxyEthyyl Methylcellse ku mikorere ya sima. HydroxyEthyyl methylcellse ni ifu idafite impumuro nziza, idafite uburozi, idatsinzwe, ishobora gushonga mumazi akonje kugirango akore igisubizo gisobanutse. Ifite ibiranga ibiranga, guhuza, gutatana, kurengana, gushiraho film, guhagarikwa, gukomera, gukomeza ubushuhe no kurinda ubushuhe no kurinda ubushuhe no kurengera colloid no kurinda ubushuhe no kurengera colloid. Kubera ko igisubizo cy'amazebwe gifite imikorere ikora cyane, irashobora gukoreshwa nk'umukozi uriganya ya Colloical, Emalifier no gutabarwa. Hydroxyyethyy Methylcellus igisubizo cy'amazi afite hydrofili nziza kandi ni ushinzwe kugumana amazi meza.

2. Irangi ryoroheje cyane rirateguwe, rikozwe mu bikoresho fatizo bikurikira mu bice n'uburemere: 150-200 g cy'amazi ya deionized; 60-70 g ya emulic nziza ya acryccion; 550-659 g ya calcium iremereye; 70-90 g ya talcum ifu; Shingiro na selile iratanga umusaruro 30-40g; lignocellse igisubizo cya 10-20G; Imfashanyo ya firime 4-6g; antiseptic na fungicicide 1.5-2.5g; gutabata 1.8-2.2g; Umukozi utose 1.8-2.2G; 3.5-4.5g; Ethylene Glycol 9-11g; Hydroxyyerthyl methylcellus igisubizo kiratangaje gikorwa no gushonga 2-4% hydroxyyerthyl methylcellse mumazi; Igisubizo cya lignocellse kiratangaje gikozwe muri 1-3% lignocellse ikorwa no gushonga mumazi.

Imyiteguro

Uburyo bwo gutegura HydroxyIthyyl Methyl Cellulose, uburyo ni bwo bupamba bunoze bukoreshwa nk'igikoresho kibisi, kandi Ethylene Oxide ikoreshwa nk'umukozi wa hantu ho gutondeka mu rwego rwo gutegura HydroxyEthyl Methyl Cellulose. Ibice byuburemere bwibikoresho fatizo byo gutegura HydroxyEthyl Methylcellse ni izi zikurikira, ibice 8-295 by'amazi, ibice 80-40 by'igice cya Methine, 16-19 ya acide yinda; Intambwe Zihariye ni:

Intambwe yambere, muri reaction Kettle, ongeraho toluene na isopropal kuvanga, amazi, na sodium, na sodium hydroxide, ubushyuhe kugeza kuri 60-80 ° C, Komeza gushyuha muminota 20-40;

Intambwe ya kabiri, alkalisation: Cool Ibikoresho byavuzwe haruguru kugeza 30-50 ° C, shyiramo ipamba rya Alkalisation, kandi uzuza allet

Intambwe ya gatatu, Gutandukanya: Nyuma ya alkalisation irangiye, reaction yimuwe kugeza kuri 0.05-0.0. Icyiciro cya mbere cyo Guhanga: 40-60 ° C, amasaha 1.0-2.0, igitutu kigenzurwa hagati ya 0.15 na 0.3mpa; Icyiciro cya kabiri cyo guhindura: 60 ~ 90 ℃, amasaha 2.0 ~ 7,000, igitutu kigenzurwa hagati ya 0.4 na 0.8mpa;

Intambwe ya kane, kutabogama: ongeraho aside iri mu kigero cy'izabukuru mu gihe cyo kugandukira, ukabandike mu buryo butamenyereye 72-80. Ikigega cyo gusezerana cyuzuyemo amazi yavuwe nigikoresho cya osmose ya osmose kuri 90 ° C kugeza 100 ° C;

Intambwe ya gatanu, Centrifugal Gukaraba: Ibikoresho biri mu ntambwe ya kane biranyeganyega mu ndege za horizontal, kandi ibikoresho byatandukanijwe byimurirwa mu gikari cyo gukaraba cyuzuyemo ibikoresho bishyushye mbere yo gukaraba ibikoresho;

Intambwe ya gatandatu, centrifugal yumye: Ibikoresho byogejwe byatanzwe mumene unyuze mu gisirikare cya horizontal, kandi ibikoresho byumye kuri 150-170 ° C, kandi ibikoresho byumye birajanjagurwa kandi bipakiye.

Ugereranije na tekinoroji ya Celolose Ifite viscosity Stcosity Itumanaho ryibishobora no kurwanya ibyombora mugihe cyo kubika igihe kirekire. Irashobora gukoreshwa aho kuba andi bahanga muri selile.
