Motsoako oa metsi ke motsoako oa konkreite o ka fokotsang bongata ba metsi a kopanyang ha o ntse o boloka ho putlama ha konkreite. Boholo ba bona ke li-anionic surfactants. Ka mor'a ho eketsoa ka motsoako oa konkreite, e na le phello ea ho qhalakanya likaroloana tsa samente, tse ka ntlafatsang ts'ebetso ea eona, ho fokotsa tšebeliso ea metsi a yuniti, le ho ntlafatsa metsi a motsoako oa konkreite; kapa fokotsa tšebeliso ea samente le ho boloka samente.
Ho ea ka ponahalo:
E arotsoe ka metsi-based le powder-based. Lintho tse tiileng tsa metsi a thehiloeng ka kakaretso ke 10%, 20%, 40% (e tsejoang hape e le joala ba 'mè), 50%,' me lintho tse tiileng tsa phofo hangata ke 98%.
Ho ea ka bokhoni ba ho fokotsa metsi le ho matlafatsa matla:
E arotsoe ka mokhoa o tloaelehileng oa ho fokotsa metsi (hape o tsejoa e le plasticizer, ka sekhahla sa phokotso ea metsi e seng ka tlase ho 8%, e emeloang ke lignin sulfonates), se fokotsang metsi se sebetsang hantle haholo (se tsejoang hape e le superplasticizer, se nang le sekhahla sa phokotso ea metsi se seng tlase ho feta. ho feta 14%, ho kenyelletsa letoto la naphthalene, letoto la melamine, letoto la aminosulfonate, letoto la aliphatic, joalo-joalo) le mochini o fokotsang metsi o sebetsang hantle (sekhahla sa phokotso ea metsi ha se tlase ho feta 25%, e emeloang ke polycarboxylic acid series water reducer), 'me e arotsoe ka mofuta oa matla a pele, mofuta o tloaelehileng le mofuta oa ho beha butle ka ho latellana.
Ho ea ka thepa ea sebopeho:
Lignin sulfonates, matsoai a nkhang hamonate a polycyclic, resin sulfonate e qhibilihang ka metsing, lisebelisoa tse fokotsang metsi tse nang le naphthalene, lisebelisoa tse fokotsang metsi tse sebetsang hantle haholo, amino tse fokotsang metsi tse sebetsang hantle haholo, li-polycarboxylate tse fokotsang metsi, joalo-joalo.
Ho ea ka sebopeho sa lik'hemik'hale:
Li-lignin sulfonate tse fokotsang metsi, tse fokotsang metsi a nang le naphthalene, tse fokotsang metsi a sebetsang hantle haholo tse thehiloeng melamine, li-aminosulfonate tse thehiloeng ho aminosulfonate, tse fokotsang metsi tse nang le mafura a mangata, li-polycarboxylate. .
Mosebetsi oa ho fokotsa metsi:
1. Ntle le ho fetola karolelano ea lihlahisoa tse sa tšoaneng (ntle le samente) le matla a konkreite, palo ea samente e ka fokotsoa.
2.Ntle le ho fetola karo-karolelano ea lihlahisoa tse sa tšoaneng tse tala (ntle le metsi) le ho theoha ha konkreite, ho fokotsa palo ea metsi ho ka ntlafatsa haholo matla a konkreite.
3. Ntle le ho fetola karo-karolelano ea lisebelisoa tse sa tšoaneng tse tala, rheology le polasetiki ea konkreite li ka ntlafatsoa haholo, e le hore kaho ea konkreite e ka etsoa ka matla a khoheli, ho pompa, ntle le ho sisinyeha, joalo-joalo, ho eketsa lebelo la kaho le ho fokotsa tšebeliso ea matla a kaho. .
4. Ho eketsa lisebelisoa tse fokotsang metsi ho konkreite ho ka eketsa bophelo ba konkreite ka makhetlo a fetang a mabeli, ke hore, ho eketsa bophelo bo tloaelehileng ba tšebeletso ea mohaho ka makhetlo a fetang a mabeli.
5.Ho fokotsa sekhahla sa ho fokotseha ha konkreite le ho thibela mapetsong a likarolo tsa konkreite; ntlafatsa ho hanyetsa serame, e leng se loketseng kaho ea mariha.
Mokhoa oa ts'ebetso ea ho fokotsa metsi:
· Phahamiso
·Lubrication
· Tšitiso e matla
· Phello e liehang ea ho lokolloa ha liketane tsa mahlakoreng a copolymer
