Viscosity ea hydroxypropyl methylcellulose hpmc ke eng?

Putty powder bakeng sa marako a ka hare hangata e na le viscosity ea 100,000. Seretse sa samente se na le litlhoko tse phahameng tsa ho lokisoa, 'me viscosity ea 150,000 e bonolo ho e sebelisa. Ho feta moo, karolo ea bohlokoa ka ho fetisisa ea HPMC ke ho notlela metsi, ho lateloe ke ho teteana. Ka putty powder, haeba ho boloka metsi ho le molemo 'me viscosity e le tlaase (7-80,000), e ka boela ea e-ba le viscosity e phahameng ea tlhaho le ho boloka metsi ho batla ho le betere. Ha viscosity e feta 100,000, viscosity ha e na phello e fokolang ho boloka metsi.

Ke phello efe ea bohlokoa eaHPMC ka putty phofo, le hore na k'hemistri ea tlhaho e etsahala?

HPMC e bapala mesebetsi e meraro ea ho tiisa, ho boloka metsi le ho haha ​​​​ka putty powder.

Thickening: Methylcellulose e ka tsepamisoa ka litharollo tse phaphametseng, tse nang le metsi ho boloka ts'ebetso e ts'oanang le e tsitsitseng le ho thibela ho fanyeha ha phallo.

Ho boloka metsi: Lerako le ka hare la phofo le omella butle, 'me kalaka e ekelitsoeng ea calcium e bonahala tšebelisong ea metsi.

Kaho ea boenjiniere: Methyl cellulose e na le phello ea lubricating, e ka etsang hore phofo ea putty e be le sebopeho se setle sa boenjiniere.

HPMC ha e amehe liphetohong tsohle tsa lik'hemik'hale empa e le tlatsetso feela. Putty phofo, leboteng, ke phetoho ea lik'hemik'hale, hobane ho na le phetoho e ncha ea lik'hemik'hale tsa lik'hemik'hale, phofo ea putty e tsoa leboteng, e sila phofo, 'me e sebelisa hape hobane ntho e ncha ea lik'hemik'hale (calcium carbonate) e hlahisitsoe.

Likarolo tse kholo tsa calcium fly ash ke: Ca(oh)2, Cao le palo e nyane ea metsoako ea Caco3, Caoh2oCa(oh)2-Ca(oh)2caco3h2o lime e ka fetoloa calcium bicarbonate metsing le khase, ha mpc e feela metsi a qhibilihang ka har'a Calcium fofa molora ke ponahatso e matla, eo ka boeona e sa kopaneleng ho bonahatsa leha e le efe.

Ke eng e lokelang ho lebisoa tlhokomelo ho ts'ebeliso ea 'nete ea kamano pakeng tsa viscosity le mocheso oa HPMC?

The viscosity ea HPMC e inversely tekano le mocheso, ka mantsoe a mang, viscosity eketseha le ho fokotseha ha mocheso. The viscosity ea sehlahisoa, viscosity ea sehlahisoa se bolela hore tharollo ea eona ea 2% e mocheso oa likhato tse 20 tsa Celsius, le liphello tsa liteko.

Lits'ebetsong tse khethehileng, tlhokomelo e lokela ho lefshoa libakeng tse nang le phapang e kholo ea mocheso pakeng tsa lehlabula le mariha, 'me ho kgothaletswa ka matla ho sebelisa viscosity e tlaase mariha. Ho seng joalo, viscosity e tlaase, viscosity ea cellulose e tla eketseha, 'me likhahla li tla ba boima.

Viscosity e bohareng: 75000-100000 e loketseng phofo ea putty
Lebaka: ho boloka metsi hantle

Viscosity e phahameng: 150000-200000 e loketse seretse sa polystyrene particle insulation le seretse sa inorganic insulation.
Mabaka: viscosity e phahameng, ho tlosoa ka thata ha seretse sa samente, ho lahleheloa ke gloss, mohaho o ntlafetseng.
