Seretse se ikemetseng se thehiloeng ho Gypsum: kakaretso
Seretse sa ho ikemela ke thepa e khethehileng ea mohaho e etselitsoeng lisebelisoa tsa fatše tse hlokang sebaka se boreleli, se lekaneng. Lisebelisoa tsena hangata li na le li-binders, aggregates le li-additives tse fapaneng ho finyella litšobotsi tse itseng tsa tshebetso. Gypsum ke liminerale tsa tlhaho tse atisang ho sebelisoa e le setlamo sa mantlha sa seretse se ikemelang ka lebaka la thepa ea eona e ikhethang, ho kenyeletsoa tlhophiso e potlakileng le ts'ebetso e ntle haholo.
Lisebelisoa tse tala bakeng sa seretse se ikemetseng sa gypsum:
1. Gypsum:
Mohloli: Gypsum ke liminerale tse ka rafshoang ho tloha li-deposit tsa tlhaho.
Mosebetsi: Gypsum e sebetsa joalo ka setlamo se seholo sa seretse sa ho ikemela. E thusa ho tiisa ka potlako le ho ntlafatsa matla.
2. Ho kopanya:
Mohloli: Aggregate e tsoa ho sediment ea tlhaho kapa lejoe le pshatlehileng.
Karolo: Likopano, joalo ka lehlabathe kapa lehlohlojane le letle, li fana ka bongata ho seretse le ho susumetsa thepa ea eona ea mochini, ho kenyelletsa matla le ho tšoarella.
3. Cellulose ether:
Mohloli: Li-cellulose ethers li tsoa mehloling ea tlhaho ea cellulose joalo ka makhasi a lehong kapa k'hothone.
Mosebetsi: Cellulose ether e sebetsa e le mofetoleli oa rheology le moemeli oa ho boloka metsi ho ntlafatsa ts'ebetso, ho khomarela le ts'ebetso e akaretsang ea seretse se ikemetseng.
4. Setsi se fokotsang metsi se sebetsang hantle haholo:
Mohloli: Li-superplasticizers ke li-polymer tsa maiketsetso.
Mosebetsi: Setsi sa ho fokotsa metsi se sebetsang hantle haholo se ntlafatsa ho phalla ha metsi le ho sebetsa ha seretse ka ho fokotsa metsi, ho etsa hore ho be bonolo ho beha le ho ba boemong.
5. Retarder:
Mohloli: Li-retarders hangata li thehiloe ho metsoako ea lintho tse phelang.
Mosebetsi: Retarder e ka fokotsa nako ea ho beha seretse, ea eketsa nako ea ho sebetsa le ho khothaletsa ts'ebetso ea ho lekanya.
6. Ho tlatsa:
Mohloli: Li-fillers li ka ba tsa tlhaho (joalo ka limestone) kapa tsa maiketsetso.
Mosebetsi: Li-filler li kenya letsoho bophahamong ba seretse, li matlafatsa molumo oa tsona le ho ama thepa e kang density le thermal conductivity.
7. Fiber:
Mohloli: Lithapo li ka ba tsa tlhaho (mohlala, likhoele tsa cellulose) kapa tsa maiketsetso (mohlala, polypropylene fibers).
Mosebetsi: Likhoele li eketsa matla a ho tsitsa le a flexural a seretse le ho fokotsa kotsi ea ho petsoha.
8. Metsi:
Mohloli: Metsi a lokela ho hloeka 'me a loketse ho nooa.
Mosebetsi: Metsi a bohlokoa bakeng sa ts'ebetso ea hydration ea samente le lisebelisoa tse ling, a kenya letsoho ntlafatsong ea matla a seretse.
Mokhoa oa Tlhahiso:
Ho lokisoa ha lintho tse tala:
Gypsum e rafshoa le ho sebetsoa ho fumana phofo e ntle.
Aggregate e bokelloa ebe e pshatleha ka boholo bo hlokahalang.
Li-cellulose ethers li hlahisoa ho tsoa mehloling ea cellulose ka ts'ebetso ea lik'hemik'hale.
motsoako:
Gypsum, aggregate, cellulose ethers, superplasticizer, retarder, fillers, fibers le metsi li lekantsoe hantle le ho tsoakoa ho fihlela motsoako o tšoanang.
QC:
Motsoako ona o etsa liteko tse matla tsa taolo ea boleng ho netefatsa hore o kopana le botsitso bo boletsoeng, matla le litekanyetso tse ling tsa ts'ebetso.
Sephutheloana:
Sehlahisoa sa ho qetela se pakoa ka mekotleng kapa lijaneng tse ling bakeng sa ho ajoa le ho sebelisoa libakeng tsa kaho.
ha re phethela:
Ho hlahisa li-gypsum-based self-leveling mortars ho hloka khetho e hlokolosi le ho kopanya lisebelisoa tse tala ho finyella thepa e hlokahalang. Li-cellulose ethers li phetha karolo ea bohlokoa e le li-additives tse ntlafatsang ho sebetsa, ho khomarela le ho sebetsa ka kakaretso ha seretse. Ha indasteri ea kaho e ntse e tsoela pele ho fetoha, lipatlisiso le nts'etsopele ea mahlale a thepa li ka lebisa ntlafatsong e eketsehileng ea seretse sa ho ikemela, ho kenyeletsoa ts'ebeliso ea li-additives tse ncha le lisebelisoa tse tala tse tšoarellang.
