Uruhare rukomeye rwo gushonga amazihydroxypropyl methyl selulose HPMCmuri minisiteri ni ngombwa mubice bitatu, kimwe nubushobozi buhebuje bwo gufata amazi, bibiri ni ibyangiritse ku bwenge no kwikomeretsa bya minisiteri, bitatu ni imikoranire na sima. Kugumana amazi mabi ya minisiteri muburyo bwose bwo gutwara biroroshye gutandukanya amazi asohoka, gukwirakwira hejuru yibintu byoroshye, amazi menshi aroroshye kuyakuramo kugirango asogonge, bitange impinduka ziranga minisiteri, minisiteri yangiza ibyangiritse ibintu byose bisanzwe coagulation hamwe nuduce duto twibikoresho fatizo hagati yo guhuza bityo bigabanye imbaraga zo kwikuramo urukuta rwa masonry. Kubika amazi ya minisiteri bisobanurwa na stratifike.
Kurenza ubwiza bwahydroxypropyl methyl seluloseHPMC, uburyo bwiza bwo gufata amazi, niko ubwiza bwumuti wa polymer wamazi. Uburebure n'imiterere y'urunigi rwa molekile nabyo biterwa na misile igereranije ya polymer (ubushyuhe bwikirahure). Umubare wamatsinda akora nayo agira ingaruka kumurongo.
Hydroxypropyl methyl selulose HPMC ifite imikorere yo gufata amazi kuva hydroxypropyl methyl selulose yonyine kandi ikanakoresha amazi. Birazwi neza ko selile idashobora gushonga mumazi kubera imiterere yayo yo hejuru ya kristaline, nubwo urunigi rwa molekile ya fibre irimo amatsinda menshi ya OH afite amazi menshi.
Imbaraga zidasanzwe za covalent hamwe na van der Waals imbaraga hagati yimiterere ya molekile ntishobora kwishyurwa nubushobozi bwo kuyobora amatsinda ya methyl yonyine. Kubwibyo, irashobora gushonga mumazi gusa. Iyo molekile isimbuye itangijwe, ntabwo molekile isimbuza gusa isenya urunigi rwa hydrogène, ariko kandi imigozi ya covalent mumurongo wa hydrogène isenywa na molekile isimburanya muminyururu ituranye. Nibisimburwa byinshi, niko intera ya molekulari nini. Nibyinshi byingirakamaro kumena covalent bonds. Iyo fibre ya fibre ihora yaguka, igisubizo cyamazi cyinjira hanyuma hydroxypropyl methyl selulose ihinduka amazi, bikavamo igisubizo cyamazi menshi cyane.
Mugihe ubushyuhe bwibidukikije buzamuka, hydrime ya polymer iba nkeya kandi amazi yirukanwa hagati yumunyururu. Iyo amazi ahagije akuweho, imiterere ya molekile iragenda yegeranya buhoro buhoro, itanga urusobe rwibice bitatu byimyenda ishobora kuramburwa. Ubukonje, ibipimo, ingano yubushyuhe hamwe nubushyuhe bwa hydroxypropyl methyl selulose nibintu byangiza imikorere yo gufata amazi ya minisiteri.
Hydroxypropyl methyl selulose viscosity igabanijwemo: viscosity 100.000, viscosity 150.000, viscosity 200,000.
Nigute ushobora guhitamo hydroxypropyl methyl selulose?
100.000 viscosity hydroxypropyl methyl selulose irashobora gukoreshwa nkifu yimbere yimbere. Amabati. Umukozi. Amabuye ya beto. Gukomera cyane ntabwo kugabanya ibikoresho byo gutaka.
Inorganic insulation insulation mortar ibisobanuro biri hejuru, ubukonje bwibihumbi 150 hydroxypropyl methyl selulose cyangwa ibihumbi 200 hydroxypropyl methyl selulose. Niba uhisemo imbuto nshya ko viscosity ari ibihumbi 100, tanga umuvuduko wo kumanika ibintu byoroshye.
Uruhare rwiganjemo methyl selulose ni ukubika amazi, hagakurikiraho kubyimba. Kurambirwa nifu yumwana murukuta rwimbere, niba ifite amazi meza gushonga hamwe nubwiza buke (70000-80000), urashobora gusaba. Iyo ubwiza burenze 100.000, ubwiza ntibwangiza kubika amazi. Mu gukora no gukora ifu yimbere yimbere, nta mpamvu yo guhitamo ibishishwa 200.000. Kuberako ibishishwa ari binini cyane, biragoye gushushanya no gushushanya kubwinshi.
Hydroxypropyl methyl selulose ikoresha ubwiza bwa 100.000.
1.
Amazi menshi arashobora gukora beto ihagije, imbaraga zifatika zikomeza kwiyongera. Mu buryo nk'ubwo, imbaraga zo guhonyora hamwe no gukata lazeri imbaraga zo gukomeretsa zirashobora kunozwa muburyo bukwiye, hanyuma bigatezimbere ingaruka ziteganijwe zo kubaka, kunoza imikorere.
2. Urukuta rw'imbere rushyiramo ifu irwanya ubukana.
Muri putty, moisturizing, bonding, amavuta ni ngombwa cyane, kugirango wirinde ubwinshi bwamazi aterwa no guturika hamwe nubutaka bwumye nabyo bitezimbere guhuza ifu yinkuta yimbere imbere, kugabanya ibintu bimanikwa mumyubakire, kubaka ubwubatsi ugereranije neza.
3. Amashanyarazi ya Paris yoza ibicuruzwa byuruhererekane.
Muri plaster yibicuruzwa bya Paris, bifite ingaruka nyamukuru zo gufata amazi, kubyimba no gutose. Nkibyo, bifite ingaruka zambere zo gushiraho, zishobora kongera igihe cyubwubatsi no gukemura ibibazo byo guturika nimbaraga zumwimerere zo kwikuramo mubikorwa byubwubatsi.
4. Amashanyarazi adafite amazi.
Nkibikorwa byingenzi bya demulifisiferi, birashobora kunoza imbaraga zingutu hamwe no gukata lazeri imbaraga zo kwikomeretsa, kunoza igifuniko cyo hejuru, kunoza guhuza no guhuza imbaraga zo kwikuramo.
5. Ceramic tile yometseho.
Amabati maremare yamashanyarazi hamwe ninganda zinganda ntizigomba gutose cyangwa gutose hakiri kare, ibyo bikaba byongera imbaraga zo guhuza imbaraga. Igihe cyo kubaka ni kirekire, cyoroshye kandi kimwe, gikiza igihe n'imbaraga mubwubatsi. Mubyongeyeho, ifite kandi amavuta meza yo kwisiga.
6. Umukozi wo gukurura. Ikidodo.
Fibre ya HPMC ifite ireme ryiza, kugabanuka guke no kwihanganira kwambara cyane, gufata neza ibikoresho fatizo bitangirika kwangiza ibikoresho byinganda, kugirango hirindwe kwinjira mumishinga yose yubwubatsi.
7. Dc ibikoresho bisanzwe.
Ubushobozi bwo guhuza neza butuma sisitemu yo kuzenguruka yujuje ubuziranenge bwa sima, igahindura igipimo cyo kugumana amazi kugira ngo ikomere vuba kandi igabanye gucika no gufunga.
8. Irangi ryinganda murukuta latex irangi.
Mu nganda zitunganya inganda n’inganda, methylpropyl methyl selulose irashobora gukoreshwa nkumukozi ukora firime, demulsifier, demulsifier na adhesive, kugirango firime igire imyambarire myiza yo kwambara, imikorere ikozwe neza, ifatanye hamwe nubushyuhe bwa pH bifite agaciro. gutera imbere. Ibisubizo biteganijwe nabyo nibyiza iyo bivanze numusemburo kama. Ifite ubushyuhe bwinshi kandi ikora neza.
Hydroxypropyl methyl selulose 1500000 viscosity.
Hagati ya 100.000 yubukonje hamwe na 200.000 viscosity, 150.000 viscosity hafi 100.000.
Hydroxypropyl methyl selulose ikoreshwa 200.000.
Mu bikoresho byo kubaka, cyane cyane ikoreshwa rya insorganic insulateri ya minisiteri, ikintu cyingenzi nukuzamura ubumwe, kongera imbaraga zinguvu, gukora minisiteri ya beto byoroshye gufunga, kunoza imikorere. Mubyongeyeho, ifite anti-vertical liquidité. Imikorere ihanitse cyane irashobora kongera igihe cyo gukora cya beto ya beto, kunoza imvune no kuvunika, kunoza ubwiza bwubutaka, kunoza neza.
. Muri rusange, umubare wongeyeho ni munini, ubwiza ni buto, ubwiza ni bunini, igipimo cyo gufata amazi ni kinini, muri byo amafaranga yiyongereye agira uruhare runini ku kigero cyo gufata amazi, ubukonje n’igipimo cyo gufata amazi ntabwo kiri hasi kuruta umubano, igipimo cyo guseswa ahanini biterwa nurwego rwo guhindura isura hamwe nubunini bwa selile ya selile. Methyl selulose na hydroxypropyl methyl selulose muri ethers nyinshi za selile nyinshi zifite umuvuduko mwinshi wo gufata amazi.
