Ke mefuta efe ea mefuta e fokotsang metsi 'me litšobotsi tsa tsona ke life?

Lisebelisoa tse fokotsang metsi, tse tsejoang hape e le li-plasticizers kapa superplasticizers, ke li-additives tsa lik'hemik'hale tse sebelisoang ka konkreite le metsoako ea seretse ho ntlafatsa ts'ebetso, ho fokotsa metsi le ho ntlafatsa ts'ebetso ea thepa. Ho na le mefuta e mengata ea lisebelisoa tse fokotsang metsi, e 'ngoe le e 'ngoe e na le litšobotsi tsa eona le tšebeliso ea eona. Mefuta e meng e tloaelehileng ke ena:

1. Lignosulfonates: Lignosulfonates li nkiloe makhasi a lehong 'me ke e' ngoe ea mefuta ea khale ka ho fetisisa ea ho fokotsa metsi. Hangata li sebelisoa ka metsoako ea konkreite ho ntlafatsa ts'ebetso le ho fokotsa metsi a mangata ha li ntse li boloka matla a lekaneng. Lignosulfonates li na le litšenyehelo tse ngata ebile li lumellana le mefuta e mengata ea samente.
2. Naphthalene Sulfonates: Lisebelisoa tsa metsi tse thehiloeng ho Naphthalene sulfonate li sebetsa haholo ho fokotsa metsi ka metsoako ea konkreite ha li ntse li ntlafatsa ho phalla le ho sebetsa. Li loketse ka ho khetheha bakeng sa ho hlahisa konkreite e matla haholo ka tekanyo e tlaase ea metsi ho ea samente. Naphthalene sulfonates e ka boela ea thusa ho fokotsa kotsi ea ho arohana le ho tsoa mali ka konkreite.
3. Melamine Sulfonates: Melamine e fokotsang metsi e fana ka thepa e phahameng ea ho fokotsa metsi ha e bapisoa le lignosulfonates le naphthalene sulfonates. Li fana ka ts'ebetso e ntle haholo, matla a pele a pele, le ho tšoarella ho ntlafetseng ka metsoako ea konkreite. Melamine sulfonates hangata e sebelisoa lits'ebetsong tsa konkreite tse sebetsang hantle joalo ka konkreite ea precast le prestressed.
4. Polycarboxylate Ethers (PCEs): Li-ether tsa Polycarboxylate ke moloko o mocha oa lisebelisoa tse fokotsang metsi tse tsejoang ka katleho ea tsona e phahameng le ho feto-fetoha ha maemo. Ba ka fokotsa haholo metsi ka har'a metsoako ea konkreite ha ba ntse ba boloka ho phalla le ho sebetsa ka nako e telele. Li-PCE li fana ka tšebelisano e ntle haholo le mefuta e fapaneng ea samente le metsoako 'me hangata li sebelisoa ka har'a konkreite e ikemetseng (SCC) le lits'ebetso tse phahameng tsa ts'ebetso (HPC).
5. Metsoako e Kopanetsoeng: Lisebelisuoa tse ling tse fokotsang metsi li entsoe e le motsoako oa motsoako, o ka kenyelletsang motsoako oa metsoako e fapaneng ea lik'hemik'hale ho finyella lipakane tse itseng tsa ts'ebetso. Metsoako ena e ka fana ka litlamorao tse ts'oanang, joalo ka ts'ebetso e ntlafalitsoeng ea ho putlama, ntlafatso ea matla, kapa ho fokotseha ha moea.

Litšobotsi tsa li-agent tse fokotsang metsi li ka kenyelletsa:

• Phokotso ea Metsi: Mosebetsi o ka sehloohong oa li-agents tse fokotsang metsi ke ho fokotsa palo ea metsi a tsoakaneng a hlokahalang ho finyella botsitso bo lakatsehang ba metsoako ea konkreite kapa ea seretse. Sena se thusa ho ntlafatsa matla, ho tšoarella, le ho sebetsa ha thepa ha ho ntse ho fokotsa kotsi ea ho arohana le ho tsoa mali.
• Mokhoa oa ho sebetsa: Lisebelisoa tse fokotsang metsi li ntlafatsa ho sebetsa le ho phalla ha metsoako ea konkreite, ho lumella ho behoa habonolo le ho kopanya ntle le ho tela matla kapa momahano. Ba thusa ho etsa bonnete ba kabo e tšoanang ea li-aggregates le lisebelisoa tsa samente nakong eohle ea motsoako.
• Ho lumellana: Lisebelisoa tse fokotsang metsi li lokela ho lumellana le li-admixtures tse ling le li-additives tse sebelisoang ka metsoako ea konkreite, joalo ka li-air-entraining agents, li-set retarders, le li-accelerator. Ho lumellana ho tiisa hore thepa e lakatsehang le ts'ebetso ea konkreite li finyelloa ntle le liketso tse mpe kapa litla-morao.
• Sekhahla sa Tekanyo: Ho sebetsa hantle ha liente tse fokotsang metsi ho ipapisitse le sekhahla sa litekanyetso, seo hangata se hlahisoang e le peresente ea lintho tse entsoeng ka samente motsoakong. Litefiso tse nepahetseng tsa litekanyetso li ka fapana ho latela lintlha tse joalo ka mofuta oa samente, litšobotsi tse kopaneng, mocheso oa tikoloho le thepa ea konkreite e lakatsehang.
• Nako ea ho Beha: Lisebelisoa tse ling tse fokotsang metsi li ka susumetsa nako ea ho beha metsoako ea konkreite, ebang ke ho potlakisa kapa ho chechisa linako tsa ho beha pele le tsa ho qetela. Tekanyo e nepahetseng le khetho ea lisebelisoa tsa ho fokotsa metsi lia hlokahala ho fihlela maemo a lakatsehang bakeng sa lits'ebetso tse khethehileng tsa kaho.
• Litšenyehelo le Ts'ebetso: Lits'oants'o tse kang ho boloka litšenyehelo, litlhoko tsa ts'ebetso, le litlhaloso tsa morero li phetha karolo ea bohlokoa ho khetheng moemeli ea nepahetseng oa ho fokotsa metsi bakeng sa kopo e itseng. Ho bohlokoa ho lekola melemo le mefokolo ea mefuta e fapaneng ea lisebelisoa tse fokotsang metsi ho fumana khetho e nepahetseng bakeng sa litlhoko tsa projeke.

lisebelisuoa tse fokotsang metsi li bapala karolo ea bohlokoa ho ntlafatsa ts'ebetso le ho tšoarella ha metsoako ea konkreite le seretse, ho lumella mekhoa e metle ea ho haha ​​le ho ntlafatsa boleng ba mehaho e felileng.
