06. Ubushyuhe bw'ubuso: 2% by'umuti w'amazi ni 42 ～56dyn/cm.
07. Bishongesha mu mazi no mu bintu bimwe na bimwe bishongesha, nka ethanol/amazi, propanol/amazi, trichloroethane, nibindi mu rugero rukwiye.
Ibisubizo by'amazi bikoresha ubuso. Umucyo mwinshi, imikorere ihamye, ubushyuhe bwa gel bw'ibicuruzwa bifite imiterere itandukanye
Bitandukanye, uburyo bwo gushonga buhinduka bitewe n’ubukana, uko ubukana bugabanuka, uko gushonga kuba kwinshi, imikorere y’ibipimo bitandukanye bya hydroxypropyl methylcellulose (HPMC) igira itandukaniro, gushonga kwa hydroxypropyl methylcellulose (HPMC) mu mazi ntibigira ingaruka ku ngaruka za PH.
08. Iyo ingano ya methoxyl igabanutse, urugero rwa gel ruriyongera, ubushobozi bwo gushonga mu mazi buragabanuka, kandi imikorere y'ubuso bwa hydroxypropyl methylcellulose (HPMC) nayo iragabanuka.
09. Hydroxypropyl methylcellulose (HPMC) ifite ubushobozi bwo gukuba, irwanya umunyu, ifu y'ivu nke, ihindagurika rya PH, ifata amazi, ihindagurika ry'ibipimo, ubushobozi bwiza bwo gukora filime, hamwe n'uburyo bwinshi bwo kurwanya enzymes, imiterere yo gukwirakwira nk'igitsina no gufatana.
Icya gatatu, imiterere ya hydroxypropyl methylcellulose (HPMC):
Iki gicuruzwa gihuza imiterere myinshi ifatika n'iya chimique kugira ngo kibe ikintu cyihariye gifite akamaro kenshi, kandi imiterere itandukanye ni iyi ikurikira:
(1) Kubika amazi: Bishobora kubika amazi ku buso bufite imyenge nk'imbaho za sima zo ku nkuta n'amatafari.
(2) Imiterere ya firime: Ishobora gukora firime ibonerana, ikomeye kandi yoroshye kandi irwanya amavuta neza.
(3) Gushonga kw'ibinyabuzima: Iki gicuruzwa gishongeshwa mu bintu bimwe na bimwe by'umwimerere, nka ethanol/amazi, propanol/amazi, dichloroethane, na sisitemu y'ibintu by'umwimerere igizwe n'ibintu bibiri by'umwimerere.
(4) Gushyushya: Iyo umuti w'amazi w'umuti ushyushye, uzakora gel, maze gel yakozwe ikongera kuba umuti nyuma yo gukonja.
(5) Ibikorwa byo hejuru: Gutanga ibikorwa byo hejuru mu gisubizo kugira ngo hagerwe ku gukurura no kurinda koloyide, ndetse no gushimangira icyiciro.
(6) Guhagarika: Bishobora kubuza imvura kugwa kw'uduce duto, bityo bikabuza ikorwa ry'ibishishwa.
(7) Koloyide irinda: ishobora kubuza ibitonyanga n'uduce duto guhuriza hamwe cyangwa gufungana.
(8) Gufata neza: Ikoreshwa nk'umuti wo gufata irangi, ibikomoka ku itabi, n'ibikomoka ku mpapuro, ifite imikorere myiza cyane.
(9) Gushonga kw'amazi: Iki gicuruzwa gishobora gushonga mu mazi mu rugero rutandukanye, kandi ingano yacyo ntarengwa igengwa gusa n'ubushyuhe.
(10) Kutagira ionic: Iki gicuruzwa ni eteri ya cellulose itari ionic, idahuzwa n'umunyu w'icyuma cyangwa izindi iyoni kugira ngo habeho ibintu bidashonga.
(11) Gukomera kw'aside-base: bibereye gukoreshwa mu rugero rwa PH3.0-11.0.
(12) Nta buryohe cyangwa impumuro, ntabwo bigizweho ingaruka n'imikorere y'umubiri; bikoreshwa nk'inyongera mu biribwa no mu miti, ntabwo bizahinduka mu biribwa kandi ntabwo bizatanga karori.
4. Uburyo bwo gusenya Hydroxypropyl methylcellulose (HPMC):
Iyo ibikoresho bya hydroxypropyl methylcellulose (HPMC) byongewe mu mazi, birafungana hanyuma bigashonga, ariko uku gushonga biratinda cyane kandi biragoye. Hari uburyo butatu bwo gushonga bwatanzwe hepfo, kandi abakoresha bashobora guhitamo uburyo bworoshye bitewe n'uko bukoreshwa:
1. Uburyo bwo gukoresha amazi ashyushye: Kubera ko hydroxypropyl methylcellulose (HPMC) idashonga mu mazi ashyushye, icyiciro cya mbere cya hydroxypropyl methylcellulose (HPMC) gishobora gukwirakwizwa mu mazi ashyushye ku buryo bungana, hanyuma iyo bikonje, hasobanurwa uburyo butatu busanzwe bukurikira:
1). Shyira amazi ashyushye akenewe mu gikoresho hanyuma uyashyushye kugeza kuri dogere selisiyusi 70. Shyiramo buhoro buhoro hydroxypropyl methylcellulose (HPMC) ukoresheje uburyo bwo kuvanga buhoro buhoro, hydroxypropyl methylcellulose (HPMC) itangira kureremba hejuru y'amazi, hanyuma buhoro buhoro igakora ubushyuhe, ukonjeshe ubushyuhe ukoresheje uburyo bwo kuvanga.
2). Shyushya 1/3 cyangwa 2/3 (ingano ikenewe) y'amazi mu gikoresho hanyuma uyashyushye kugeza kuri 70°C. Dukurikije uburyo bwa 1), shyiramo hydroxypropyl methylcellulose (HPMC) kugira ngo utegure amazi ashyushye. Hanyuma ongeramo amazi akonje cyangwa amazi y'urubura asigaye mu gikoresho, hanyuma ongeramo amazi ashyushye ya hydroxypropyl methylcellulose (HPMC) yavuzwe haruguru mu mazi akonje, hanyuma uvange, hanyuma ukonjeshe uruvange.
3). Shyiramo 1/3 cyangwa 2/3 by'amazi akenewe mu gikoresho hanyuma ushyushye kugeza kuri 70°C. Dukurikije uburyo bwa 1), shyiramo hydroxypropyl methylcellulose (HPMC) kugira ngo utegure amazi ashyushye; Amazi akonje cyangwa barafu asigaye yongerwa mu mazi ashyushye hanyuma uruvange rugakonjeshwa nyuma yo kuvanga.
2. Uburyo bwo kuvanga ifu: uduce tw'ifu ya hydroxypropyl methylcellulose (HPMC) n'ibindi bintu bingana cyangwa byinshi bivanze n'ifu bikwirakwizwa neza binyuze mu kuvanga byumye, hanyuma bigashonga mu mazi, hanyuma hydroxypropyl methylcellulose Base cellulose (HPMC) ishobora gushonga hatabayeho guterana. 3. Uburyo bwo kunywesha solvent ya organique: hydroxypropyl methylcellulose (HPMC) itarakwirakwizwa cyangwa ikanyobwa hamwe n'ibintu bivanze nka ethanol, ethylene glycol cyangwa amavuta, hanyuma ikayishonga mu mazi. Muri iki gihe, hydroxypropyl methylcellulose (HPMC) nayo ishobora gushonga neza.
5. Imikoreshereze y'ingenzi ya hydroxypropyl methylcellulose (HPMC):
Hydroxypropyl methylcellulose (HPMC) ishobora gukoreshwa nk'ikintu gikomeza ubushyuhe, gikwirakwiza, gitera ubushyuhe n'imashini zikora filime. Ibicuruzwa byayo byo mu rwego rw'inganda bishobora gukoreshwa mu bintu bya buri munsi, mu bikoresho by'ikoranabuhanga, mu by'ubwubatsi no mu byo gusiga.
1. Guhindura imiterere y'umuvuduko w'amazi:
Mu gukora resins zikoze mu buryo bwa sintetiki nka polyvinyl chloride (PVC), polyvinylidene chloride n'izindi copolymers, polymerization yo gusunika ni yo ikoreshwa cyane kandi ni ngombwa kugira ngo monomers zisunika mu mazi zihamye. Nk'umubumbe ushongesha mu mazi, hydroxypropyl methylcellulose (HPMC) ifite imikorere myiza ku buso kandi ikora nk'ikintu kirinda colloidal, gishobora gukumira kwiteranya kw'uduce twa polymer. Byongeye kandi, nubwo hydroxypropylmethylcellulose (HPMC) ari polymeri ishongesha mu mazi, inashongesha gato muri monomers zisunika mu mazi kandi yongera ubwiyongere bwa monomers zikomokaho uduce twa polymeri, ku buryo ishobora guha polymers ubushobozi bwiza bwo gukuraho monomers zisigaye no kongera uburyo bwo kwinjiza plasticizers.
2. Mu gukora ibikoresho by'ubwubatsi, hydroxypropyl methylcellulose (HPMC) ishobora gukoreshwa muri ibi bikurikira:
1). Igikoresho cyo gufata no gufunga cya tepi ikoze muri gypsum;
2). Guhuza amatafari, amatafari n'ishingiro bishingiye kuri sima;
3). Stucco ishingiye kuri plasterboard;
4). Sima ishingiye ku gishushanyo mbonera;
5). Mu buryo bwo gukuraho irangi n'irangi.
