Palo ea HPMC e sebelisoang lits'ebetsong tse sebetsang e fapana ho itšetlehile ka boemo ba leholimo, mocheso, boleng ba molora oa calcium oa sebakeng seo, foromo ea putty powder le "boleng bo hlokoang ke bareki". Ka kakaretso, e pakeng tsa 4 kg le 5 kg. Ka mohlala: boholo ba phofo ea putty Beijing ke 5 kg; boholo ba phofo ea putty Guizhou ke 5 kg lehlabula le 4,5 kg mariha; palo ea putty ho Yunnan e batla e le nyane, ka kakaretso ke 3 kg ho isa ho 4 kg, joalo-joalo.
Ke viscosity e nepahetseng ea hydroxypropyl methylcellulose (HPMC) bakeng sa tlhahiso ea putty powder?
Putty powder ka kakaretso ke li-yuan tse 100,000, 'me litlhoko tsa seretse li holimo,' me li-yuan tse 150,000 lia hlokahala bakeng sa tšebeliso e bonolo. Ho feta moo, mosebetsi oa bohlokoa ka ho fetisisa oa HPMC ke ho boloka metsi, ho lateloa ke ho teteaneng. Ka phofo ea putty, hafeela ho boloka metsi ho le molemo 'me viscosity e tlaase (70,000-80,000), hape e ka khoneha. Ha e le hantle, ha viscosity e phahame, ho molemo ho boloka metsi a lekanyelitsoeng. Ha viscosity e feta 100,000, viscosity e tla ama ho boloka metsi. Ha ho sa le joalo.
Mosebetsi o ka sehloohong oa ts'ebeliso ea HPMC ka putty powder ke ofe?
Ka phofo ea putty, HPMC e bapala likarolo tse tharo tsa ho tiisa, ho boloka metsi le ho haha.
Thickening: Cellulose e ka teteaneng ho emisa le ho boloka seaparo sa tharollo holimo le tlase, le ho hanela ho theoha.
Ho boloka metsi: etsa hore phofo ea putty e ome butle-butle, 'me u thuse molora oa calcium ho itšoara tlas'a ketso ea metsi.
Kaho: Cellulose e na le phello ea lubricating, e ka etsang hore phofo ea putty e be le mohaho o motle.
HPMC ha e nke karolo ho liphetoho leha e le life tsa lik'hemik'hale, empa e bapala karolo ea thuso feela. Ho eketsa metsi ho phofo ea putty le ho e beha leboteng ke karabelo ea lik'hemik'hale, hobane lintho tse ncha li thehoa. Haeba u tlosa phofo ea putty leboteng ho tloha leboteng, u e sila ka phofo, 'me ue sebelise hape, e ke ke ea sebetsa hobane lintho tse ncha (calcium carbonate) li entsoe. ) hape. Likarolo tse kholo tsa phofo ea calcium ea molora ke: motsoako oa Ca(OH)2, CaO le chelete e nyenyane ea CaCO3, CaO H2O=Ca(OH)2—Ca(OH)2 CO2=CaCO3↓ H2O Karolo ea molora oa calcium. ka CO2 ka metsing le moeeng Tlas'a boemo bona, calcium carbonate e hlahisoa, ha HPMC e boloka metsi feela, e thusang ho itšoara hantle ha molora oa molora, 'me ha e kopanele karabelo leha e le efe ka boeona.
