Sesenyi sa metsi ke eng?
Setsi se fokotsang metsi, se tsejoang hape e le dispersant kapa plasticizer, ke sehlomathiso se sebelisoang ka ho fetesisa le sa bohlokoa ka ho fetesisa ka konkreite e seng e lokisitsoe. Ka lebaka la ho adsorption le ho hasana ha eona, ho kolobisa le liphello tse thellang, e ka fokotsa haholo tšebeliso ea metsi ea konkreite e ncha ka ts'ebetso e ts'oanang ea ts'ebetso ka mor'a tšebeliso, kahoo e ntlafatsa haholo matla, nako e telele le thepa e meng ea konkreite.
Moemeli o fokotsang metsi o ka aroloa ka mefuta e 'meli ho latela phello ea ona ea ho fokotsa metsi: e tloaelehileng ea ho fokotsa metsi le e sebetsang hantle haholo e fokotsang metsi. Setsi sa ho fokotsa metsi se ka kopanngoa le lisebelisoa tse ling ho theha mofuta oa matla a pele, mofuta o tloaelehileng, mofuta oa ho khutlisa le moea o fokotsang metsi ho latela litlhoko tsa boenjiniere ts'ebetsong.
Lisebelisoa tse fokotsang metsi li ka aroloa ka lignosulfonate le li-derivatives tsa eona, polycyclic e nkhang hamonate ea sulfonic acid, letsoai le qhibilihang ka metsing le resin sulfonic acid, aliphatic sulfonic acid salts, polyols e phahameng, letsoai la hydroxy carboxylic acid, polyol complexes, polyoxyethylene ethers le lihlahisoa tsa tsona. likarolo tse kholo tsa lik'hemik'hale.
Mokhoa oa ts'ebetso oa ho fokotsa metsi ke ofe?
Lisebelisoa tsohle tse fokotsang metsi li sebetsa ka holim'a metsi. Phello ea ho fokotsa metsi ea sesebelisoa se fokotsang metsi e bonoa haholo-holo ke mosebetsi o ka holimo oa ntho e fokotsang metsi. Mokhoa o ka sehloohong oa ts'ebetso ea ho fokotsa metsi ke o latelang:
1) Mochine o fokotsang metsi o tla adsorb ho sebopeho se tiileng-metsi, ho fokotsa tsitsipano ea holim'a metsi, ho ntlafatsa metsi a holim'a likaroloana tsa samente, ho fokotsa ho se tsitse ha thermodynamic ea ho hasana ha samente, 'me kahoo ho fumana botsitso bo lekanyelitsoeng.
2) The reducer metsi tla hlahisa adsorption directional holim'a likaroloana tsa samente, e le hore holim'a likaroloana samente tla ba le qoso e tšoanang, generating electrostatic repulsion, kahoo ho senya sebopeho flocculated ea likaroloana tsa samente le qhalakanya likaroloana samente. Bakeng sa polycarboxylate le sulfamate superplasticizers, adsorption ea superplasticizer e ka sebopeho sa selikalikoe, terata le lisebelisoa, kahoo e eketsa sebaka se pakeng tsa likaroloana tsa samente ho hlahisa electrostatic repulsion, e bontšang ho hasana ho molemo le ho boloka ho theoha.
3) Filimi ea metsi a qhibilihisitsoeng e thehoa ka mokhatlo oa hydrogen bond pakeng tsa ho fokotsa metsi le limolek'hule tsa metsi ho hlahisa tšireletso ea sebaka, ho thibela ho kopana ka ho toba ha likaroloana tsa samente le ho thibela ho thehoa ha sebopeho se khutsitseng.
4) Ha lesela la adsorption le thehoa holim'a likaroloana tsa samente, le ka thibela metsi a pele a samente, kahoo a eketsa molumo oa metsi a sa lefelloeng le ho ntlafatsa ho phalla ha pente ea samente.
5) Lisebelisoa tse ling tse fokotsang metsi li tla boela li hlahise palo e itseng ea li-bubble tse nyenyane ho fokotsa khohlano pakeng tsa likaroloana tsa samente, kahoo ho ntlafatsa ho hasana le botsitso ba slurry ea samente.
