Karolo ea hydroxypropyl methylcellulose ka putty
Ho tloha ho teteaneng, ho boloka metsi le kaho ea mesebetsi e meraro.
Thickening: Cellulose e ka teteaneng ho emisa, boloka motsoako oa tharollo o tsitsitse, 'me o hane ho theoha. Ho boloka metsi: Etsa hore phofo ea putty e ome butle, 'me u thuse karabelo ea molora oa calcium tlas'a ketso ea metsi. Kaho: Cellulose e na le phello ea lubricating, e ka etsang hore putty powder e be le ts'ebetso e ntle ea ho sebetsa. Hydroxypropyl methylcellulose ha e kenye letsoho karabelong efe kapa efe ea lik'hemik'hale mme e bapala karolo e thusang feela. Putty phofo e kenngoa ka metsi ho kopanya lebota, e leng lik'hemik'hale tsa lik'hemik'hale, hobane ho na le sebopeho sa ntho e ncha ea calcium carbonate. Likarolo tse ka sehloohong tsa phofo ea molora oa calcium ke: motsoako oa calcium hydroxide Ca (OH) 2, calcium oxide CaO le palo e nyenyane ea calcium carbonate CaCO3. Ash calcium e etsa calcium carbonate tlas'a ts'ebetso ea CO2 ka metsing le moeeng, ha hydroxypropyl methyl Cellulose e boloka metsi feela 'me e thusa karabelo e ntle ea molora oa calcium, eo ka boeona e sa keneng letsoho karabelong leha e le efe.
Re qala ka ho hlahloba mabaka a ho theoha ha phofo ea putty ho tloha linthong tse tala tsa putty: molora oa calcium powder, hydroxypropyl methylcellulose, phofo e boima ea calcium, molora oa calcium oa metsi.
1. Ka tlhahiso ea sebele, e le ho potlakisa ho bola, mocheso oa calcination o atisa ho eketseha ho 1000-1100 ° C. Ka lebaka la boholo bo boholo ba lisebelisuoa tse tala tsa lejoe la mokoetla kapa kabo e sa leka-lekaneng ea mocheso ka sebōping nakong ea calcination, lime hangata li na le lime e sa chesang mollo le lime e chesang ho feta tekano. Khalsiamo carbonate kalaka e ka tlas'a mollo ha e senyehe ka ho feletseng, 'me ha e na matla a momahaneng nakong ea tšebeliso, e ke keng ea fana ka matla a lekaneng a momahano ho putty, e leng se fellang ka ho tlosoa ha phofo ho bakoang ke boima bo sa lekaneng le matla a putty.
2. Lintho tse phahameng tsa calcium hydroxide ka har'a phofo ea molora oa calcium, ho molemo ho thatafala ha putty e hlahisoang. Ho fapana le hoo, ho fokotseha ha lintho tsa calcium hydroxide ka har'a phofo ea molora, ho mpefala ho thatafala ha putty sebakeng sa tlhahiso, ho bakang bothata ba ho tlosoa ha phofo le ho tlosoa ha phofo.
3. Phofo ea molora ea calcium e kopantsoe le phofo e ngata ea khalsiamo e boima, e leng se etsang hore litaba tsa molora oa molora o be tlaase haholo ho fana ka boima bo lekaneng le matla ho putty, e leng se etsang hore putty e theohe phofo. Mosebetsi o ka sehloohong oa putty powder ke ho boloka metsi, ho fana ka metsi a lekaneng bakeng sa ho thatafala ha molora oa calcium powder, le ho etsa bonnete ba ho thatafatsa ho lekaneng. Haeba ho na le bothata ka boleng ba hydroxypropyl methylcellulose kapa lihlahisoa tse sebetsang li le tlase, mongobo o lekaneng o ke ke oa fanoa, o tla etsa hore ho thatafala ho se ke ha lekana le ho etsa hore putty e theohe phofo.
E ka fumanoa ho tloha ka holimo hore boleng ba hydroxypropyl methylcellulose bo futsanehile haholo 'me bo ke ke ba finyella phello e itseng,' me putty powder e tla oa. Lebaka le ka sehloohong ke grey beggar heavy calcium.
