Metsi a Reducer Superplasticizer ka Kaho

Li-superplasticizers tse fokotsang metsi ke li-additives tsa bohlokoa indastering ea kaho, haholo mefuteng ea konkreite. Metsoako ena e etselitsoe ho ntlafatsa ts'ebetso ea metsoako ea konkreite ha e ntse e fokotsa metsi, e lebisang ho matla a matla, ho tšoarella le thepa e meng e lakatsehang. Mona ke lintlha tsa bohlokoa tsa li-superplasticizers tse fokotsang metsi kahong:

1. Tlhaloso le Mosebetsi:

• Superplasticizer e Fokotsang Metsi: Motsoako o lumellang phokotso e kholo ea metsi a motsoako oa konkreite ntle le ho senya ts'ebetso ea ona. Li-superplasticizers li hasanya likaroloana tsa samente ka mokhoa o atlehileng haholoanyane, tse lebisang ho phallo e ntlafetseng le ho fokotsa viscosity.

2. Mesebetsi ea Bohlokoa:

• Phokotso ea Metsi: Mosebetsi o ka sehloohong ke ho fokotsa tekanyo ea metsi ho ea ho samente ka metsoako ea konkreite, e lebisang ho matla a phahameng le ho tšoarella.
• Mokhoa o Ntlafetseng oa ho sebetsa: Superplasticizers e ntlafatsa ts'ebetso ea konkreite ka ho ntlafatsa phallo ea eona, ho etsa hore ho be bonolo ho e beha le ho e etsa.
• Matla a Eketsehileng: Ka ho fokotsa metsi a mangata, li-superplasticizers li kenya letsoho ho matla a holimo a konkreite, ka bobeli ka matla a ho hatella le a flexural.
• Ntlafatso ea nako e telele: compaction e ntlafetseng le ho fokotseha ho fokolang ho kenya letsoho ho tšoarella ha konkreite, ho etsa hore e be khahlanong le maemo a tikoloho.

3. Mefuta ea Superplasticizers:

• Sulfonated Melamine-Formaldehyde (SMF): E tsebahala ka matla a eona a phahameng a ho fokotsa metsi le ho boloka mosebetsi o motle.
• Sulfonated Naphthalene-Formaldehyde (SNF): E fana ka thepa e babatsehang ea ho hasanya 'me e sebetsa hantle ho fokotsa metsi.
• Polycarboxylate Ether (PCE): E tsebahala ka bokhoni ba eona bo phahameng ba ho fokotsa metsi, esita le ka tekanyo e tlaase ea litekanyetso, 'me e sebelisoa haholo ka konkreite e phahameng.

4. Melemo:

• Ts'ebetso e Ntlafetseng: Li-superplasticizers li fana ka ts'ebetso e phahameng ho metsoako ea konkreite, e etsa hore e phalle haholoanyane le ho e sebetsana habonolo nakong ea ho beoa.
• Metsi a Fokotseng: Molemo o ka sehloohong ke ho fokotseha ho hoholo ha karo-karolelano ea metsi ho ea samente, e leng se hlahisang matla a ntlafetseng le ho tšoarella.
• Khokahano e Ntlafetseng: Li-superplasticizers li ntlafatsa ho kopana ha motsoako oa konkreite, ho lumella ho kopanya hantle ntle le ho arohana.
• Ho lumellana le Li-Admixtures: Li-superplasticizers hangata li lumellana le metsoako e meng ea konkreite, e lumellang hore ho be le mekhoa e mengata le e hlophisitsoeng.
• Matla a Pele a Pele: Li-superplasticizers tse ling li ka kenya letsoho ho beheng ka potlako le ho nts'etsopele ea matla a pele ka konkreite.

5. Libaka tsa Kopo:

• Itokiselitse Kopanya Concrete: Li-superplasticizers li atisa ho sebelisoa ha ho etsoa konkreite e itokiselitseng ho ntlafatsa ho phalla ha eona le ho sebetsa ha eona nakong ea lipalangoang le ho behoa.
• Konkreite ea Ts'ebetso e Phahameng: Lits'ebetsong moo matla a phahameng, ho tšoarella, le ho kenella ho tlase ho bohlokoa, joalo ka metsoako ea konkreite e sebetsang hantle.
• Precast le Prestressed Concrete: Li-superplasticizers li atisa ho sebelisoa ha ho etsoa lisebelisoa tsa konkreite tse entsoeng esale pele le tse hatelitsoeng pele moo lisebelisoa tsa boleng bo phahameng le matla a pele li leng bohlokoa.

6. Tekanyo le Kamano:

• Tekanyetso: Tekanyo e nepahetseng ea superplasticizer e ipapisitse le lintlha tse joalo ka moralo oa motsoako, mofuta oa samente le maemo a tikoloho. Tekanyetso e feteletseng e lokela ho qojoa.
• Ho lumellana: Superplasticizers e lokela ho lumellana le metsoako e meng ea konkreite e sebelisoang motsoakong. Hangata liteko tsa ho lumellana li etsoa ho netefatsa hore motsoako oa li-admixtures o sebetsa kamoo ho reriloeng kateng.

7. Maikutlo:

• Moetso oa Motsoako: Moralo o nepahetseng oa motsoako, ho nahanoa ka mofuta oa samente, li-aggregate, le maemo a tikoloho, ke tsa bohlokoa bakeng sa tšebeliso e ntle ea li-superplasticizers.
• Mekhoa ea ho folisa: Mekhoa ea ho folisa e na le karolo ho fihlelleng thepa e lakatsehang ea konkreite. Pheko e lekaneng e bohlokoa bakeng sa nts'etsopele ea matla a nepahetseng.

Li-superplasticizers tse fokotsang metsi li amme indasteri ea konkreite haholo ka ho nolofalletsa tlhahiso ea konkreite e sebetsang hantle ka ts'ebetso e ntlafalitsoeng, matla le nako e telele. Kutloisiso e nepahetseng ea mefuta ea bona, mesebetsi, le litataiso tsa ts'ebeliso ke tsa bohlokoa bakeng sa ho fihlela litholoana tse ntle kahong ea konkreite.
