Tlhahlobo ea tekheniki e kopaneng:

1. Ho kopanya litaba ka joala ba bo-mme

Moemeli oa ho fokotsa metsi oa Polycarboxylate ke mofuta o mocha oa mokhoa o phahameng oa ho fokotsa metsi. Ha e bapisoa le li-agents tsa setso tse fokotsang metsi, e na le ho qhalana ho matla ka konkreite 'me e na le tekanyo e phahameng ea ho fokotsa metsi. Ho kopanngoa ha joala ba bo-'mè bo fokotsang metsi ho ka finyelloa ho isa bohōleng bo itseng. Ho fetola boima ba lihlahisoa tsa lihlahisoa tsa limolek'hule tsa mahlakoreng, ho bua ka kakaretso, ho kopanya pakeng tsa lino tse tahang ho ka finyella liphello tse ntle. Joala ba 'm'a a le mong bo ka kopanngoa le lino tse ngata tsa bo-'m'e ho fihlela mesebetsi ea bona, empa ho ke ho hlokomeloe hore lino tse tahang tsa boleng bo holimo, tse sebetsang hantle li hloka ho khethoa. Ka nako e ts'oanang, acid ea polycarboxylic e ke ke ea kopanngoa le lisebelisoa tse ling tse fokotsang metsi, tse kang naphthalene series le aminoxantholate.

2. Ho kopanya litaba le lisebelisoa tse ling tse sebetsang

Ts'ebetsong ea sebele ea kaho, e le ho rarolla mathata a tobaneng le mohaho oa morero, ho hlokahala ho ntlafatsa ts'ebetso ea konkreite. Haeba motsoako oa 'mè oa joala a le mong a ke ke a finyella litlhoko, tabeng ena, lisebelisoa tse ling tse nyenyane tse sebetsang, ho akarelletsa le li-thickeners, joalo-joalo, li hloka ho eketsoa ho ntlafatsa ts'ebetso ea konkreite. . Retarder e ka eketsoa ka konkreite, e leng thepa e nyenyane e fetolang moemeli oa ho fokotsa metsi ho ikamahanya le nako ea ho beha tlas'a maemo a fapaneng a mocheso. Ho eketsa karolo ea retarder ho tla fokotsa bongata ba konkreite. Ka nako e ts'oanang, ha u kopanya retarder, hoa lokela ho hlokomeloa hore retarder ka boeona e na le phello ea ho fokotsa metsi, 'me ntlha ena e lokela ho nahanoa nakong ea ts'ebetso ea motsoako oa ho fokotsa metsi. Bothata ba ho tsoa ha metsi ka konkreite bo boetse bo tloaelehile mererong. Tabeng ena, li-thickeners le li-air-entraining agents li ka sebelisoa ho ntlafatsa bothata, empa moea oa konkreite o hloka ho laoloa ka mokhoa o utloahalang, ho seng joalo matla a konkreite a tla fokotseha.
