Kusankhidwa kwa HPMC Yakuwoneka Kopanga matope owuma?

Methyl cellulose mc ndi hydroxypropyl methy celyose (hpmc) kukhala ndi mankhwala okhazikika, kukana kwa madzi, ndipo sikukhudzidwa ndi kusintha kwa PH Mtengo Wofunika. Sikuti mafakiti apamwamba, abwino. Mawonekedwe ake ndi okhazikika poyerekeza ndi mphamvu yogwirizana. Maonekedwe a mafakitale, ang'onoang'ono mphamvu. Kupanga kwa putty ufa nthawi zambiri umakhala pakati pa 50,000 ndi ma viscossies okwanira 50,000. Matope ofuula akunja amawuma ndi malo ophatikizika ndi oyenera mamasukidwe 15 mpaka 10,000, makamaka kuti achulukitse ndi zomangamanga, amatha kuchepetsa kuchuluka kwa simenti. Chosangalatsa china ndikuti matope a simenti ali ndi nthawi yolimba, pomwe imafunikira kuchiritsidwa ndipo madzi ayenera kuwongolera ndipo madzi ayenera kukhala onyowa. Chifukwa cha madzi osungidwa a cellulose, madzi ofunikira a simembala amatsimikizika kuchokera ku madzi osungidwa kwa cellulose, motero mphamvu zolimba zitha kutheka popanda kukonza.

Ponena za mtundu wa cellulose, makamaka mawilo, imatha kuyesedwa ndi wozungulira, ndipo amathanso kufananizidwa ndi njira yosavuta. Poyerekeza, tengani 1 gram ya celluuluse ndi ma viscction omwewo, onjezerani madzi okwanira, ndikuwathira nthawi yomweyo, ndikuwona kuti ndi kuwonekerako kwabwinoko, ndipo ali ndi mphamvu yabwinoko. Bwino kuwonekera, zosayera.

Carboxymethyl cellulose cmc ndi sodium carboxymethyl sturch (ma cms) ndizotsika mtengo. Amagwiritsidwa ntchito mu ufa wotsika kwambiri pamiyala yamkati. Chogwiritsidwa ntchito pofikira owuma. Chifukwa izi zimachitika ndi simenti, calcium laimu ufa, ufa wa gypsum, ndi womata zipatso.

Anthu ambiri amaganiza kuti ma cellouse awa ndi alkaline. Nthawi zambiri, simenti ndi laimu calcium ufa ndi alkalinine, ndipo akuganiza kuti atha kugwiritsidwa ntchito limodzi. Komabe, masentimita ndi masentimita si zinthu zosakwatira. Acid a chlorooacetic acid omwe amagwiritsidwa ntchito popanga machitidwe ndi acidic. Zinthu zotsalazo pamapulogalamuyi zitakumana ndi sikani calcium ufa, kuti asaphatikizidwe. Opanga ambiri atayika kwambiri chifukwa cha izi, kotero chidwi chiyenera kulipidwa.
