Putty o ikutloa a le boima
Nakong ea kaho ea putty, batho ba bang ba tla kopana le boemo boo letsoho le utloang le le boima.Lebaka le tobileng ke lefe?E ka ntlafatsoa joang?
Mabaka a tloaelehileng a etsang hore putty e ikutloe e le boima ke:
1. Tšebeliso e fosahetseng ea mohlala oa viscosity ea cellulose ether:
Tabeng ena, viscosity ea cellulose ether ka kakaretso e phahame haholo, 'me putty e entsoeng e tla ikutloa e le boima nakong ea ts'ebetso ea ho senya;
Lebaka le leng ke hore nakong ea kaho nakong ea lehlabula, tšebeliso ea hydroxypropyl methylcellulose ether e nang le mocheso o fokolang oa mocheso o phahameng o ka etsa hore putty e lahleheloe ke viscosity, e tla ama maikutlo a kaho.
2. Karolelano e fosahetseng kapa phofshoana e ntle:
Ka kakaretso, ho na le lisebelisoa tse ngata tsa gelling tse sa tloaelehang, kapa botle ba ho tlatsa bo khethiloeng bo botle haholo, bo atisang ho khomarela thipa;
Hape hoa khoneha hore e le ho fokotsa litšenyehelo, ha ho na li-additives tse fokolang ho ntlafatsa letsoho la letsoho, tse kang starch ethers le lubricants ea thixotropic.
Mekhoa ea ho ntlafatsa 1
Karolelano e nepahetseng ea thepa e tala le khetho ea fineness
Bokhabane ba thepa e tala ka kakaretso bo ka laoloa ho 150-200 mesh, 'me botle ba ho tlatsa ka kakaretso bo ka ba 325 mesh, eseng hantle haholo;
Palo ea joala ea phofo ea polyvinyl e ke ke ea feta 6%;
Hape hoa hlokahala ho ithuta ho fokotsa bongata ba lisebelisoa tsa samente tsa inorganic.Ka kakaretso, ho lekane ho laola samente ho 28% -32%, le ho sebelisa li-additives ho ntlafatsa tshebetso ea eona ka botlalo.
Mokhoa oa ho ntlafatsa 2
Khetha ether ea cellulose e nepahetseng
Ka kakaretso, re khothaletsa hydroxyethyl methyl cellulose ether ka ts'ebetso e ntlafetseng, e nang le ho hanyetsa mocheso o phahameng haholoanyane 'me e ka ikamahanya hantle le kaho ea lehlabula le ho fokotsa litšenyehelo tsa phapanyetsano ea mariha le lehlabula;
Ntho ea bohlokoa ke ho khetha ether ea cellulose e nang le viscosity e loketseng.Ka kakaretso, cellulose ether e nang le viscosity ea 80,000 ho ea ho 100,000 e lekane bakeng sa putty powder, empa palo ea cellulose ether e kenyelletsoeng e tlameha ho khethoa ka liteko tse utloahalang tsa kaho!
Mekhoa ea ho ntlafatsa 3
Kenya li-additives ho ntlafatsa maikutlo a letsoho
Qetellong, re ka nahana ka ho eketsa starch ether kapa thixotropic lubricant (bentonite) ho ntlafatsa maikutlo a seretse;
Hopola: motsoako oa mokhoa oa saense ke senotlolo sa ho rarolla bothata!
