U tseba hakae ka moemeli oa ho fokotsa metsi?

Letsatsi la poso: 9, Sep, 2024

Laqeba la metsi ke sebaka sa konkreiti se ka fokotsang palo ea metsi a kopanyang ha a ntse a boloka boroko ba konkreite. Boholo ba tsona ke li-surfactats tsa anionic. Kamora ho eketsoa motsoako oa konkreite, e na le phello ea ho ntlafatsa le ho ntlafatsa ts'ebetso ea metsi, le ho ntlafatsa phallo ea motsoako oa konkreite; kapa fokotsa tšebeliso ea setjhaba sa senjure le boloka ea sand.

Ho latela ponahalo:
E arotsoe ka lebaka la ho ipapisitsoe le metsi le phofo e thehiloeng ho metsi. Likahare tse thata tsa ho ipapisitse le metsi hangata li 10%, 20%, 40% (e boetse e tsejoang ka hore na ke li-braor), tse ngata tsa phofo hangata li 98%.

Ho fokotsa metsi a ho fokotsa basebetsi1

Ho latela bokhoni ba ho fokotsa metsi le ho ntlafatsa matla:
E arotsoe ho fokotsa metsi a tloaelehileng (e tsejoang ka hore ke ka polasetiki ea metsi ho feta 14%, ho kenyeletsoa letoto la nefthalene letoto la Mefumene, Aminosulfenate Series, setoriki sa amichetic le ho fokotsa metsi a phahameng (sekhahla sa phokotso ea metsi ha se ka tlase ho 25%, e emeloang ke lisebelisoa tsa metsi tsa Polycarboxy tsa Polycarboxy

Ho latela lisebelisoa tsa compopition:
Lignin sulfnates, li-aluble tsa metsi li qhalana, fokotsa limela tse phahameng tsa metsi, fokotsa metsi a polycarboxxx, jj.

Ho latela sebopeho sa lik'hemik'hale:
Ligramo tsa metsi, fokotsa ho fokotsa metsi le ho fokotsa metsi le ho fokotsa metsi le ho fokola ha metsi a nang le maqhubu a polycarboxxy .

Karolo ea ho fokotsa metsi:
1. Switch e fetola likhakanyo tsa lisebelisoa tse fapaneng tse fapaneng (ntle le samente) le matla a konkreite, palo ea leholeane e ka fokotsoa.
2. Mookuduteng e fetola likhaphano tsa lisebelisoa tse fapaneng (ntle le metsi) le boroko ba konkreite, ho fokotsa metsi a ka ntlafatsa matla a konkreite.
3. Mookudi ba fetola literene tsa lihlahisoa tse fapaneng, rheology le polasetiki ea konkreite e ka etsoa ka lebelo le matla la kaho .
Ho fokotsa meeli ea metsi ho qoqa ka 'mala ho ka eketsa bophelo ba konkreite ka makhetlo a mabeli ho feta habeli ho feta habeli.
5.duce sekhahla sa shrinkage sa ho hlapaola konkreite le ho thibela mapetsi ka likarolo tsa konkreiti; ntlafatsa ho hanyetsa serame, e sebetsang ho haheng mariha.
