Karolo ea Polycarboxylate Superplasticizer ho Grouting Mortars

Li-polycarboxylate superplasticizers (PCEs) ke lisebelisoa tse fokotsang metsi tse sebetsang ka mokhoa o phahameng tse sebelisoang haholo kahong, ho kenyeletsoa le libopong tsa li-grouting.Sebopeho sa bona se ikhethang sa lik'hemik'hale le thepa li etsa hore li atlehe ho ntlafatsa ts'ebetso le ts'ebetso ea lisebelisoa tsa grouting.Mona ke likarolo tsa bohlokoa tsa li-superplasticizer tsa polycarboxylate ho lirekere tsa grouting:

1. Phokotso ea Metsi:

• Karolo: Mosebetsi oa mantlha oa polycarboxylate superplasticizers ke phokotso ea metsi.Ba na le bokhoni ba ho qhala likaroloana tsa samente, ho lumella ho fokotseha ho hoholo ha metsi a grout ntle le ho tela ho sebetsa.Sena se fella ka matla a phahameng le ho tšoarella ha thepa ea grouted.

2. Matla a Ntlafetseng:

• Karolo: Li-PCE li ntlafatsa bokhoni ba ho sebetsa ha li-grouting mortars ka ho fana ka phallo e phahameng le boiketlo ba ho behoa.Sena se bohlokoa haholo lits'ebetsong moo grout e hlokang ho kenella le ho tlatsa libaka tse moqotetsane kapa li-voids.

3. Karohano e Fokotseng le ho Tsoa Mali Mali:

• Karolo: Li-superplasticizers tsa Polycarboxylate li thusa ho fokotsa karohano le litšekamelo tsa mali tsa thepa ea grouting.Sena ke sa bohlokoa bakeng sa ho fihlella kabo e tšoanang ea lintho tse tiileng, ho thibela ho rarolloa, le ho netefatsa ts'ebetso e ts'oanang.

4. Rheology e Ntlafetseng:

• Karolo: Li-PCE li fetola thepa ea rheological ea li-grouting mortars, tse susumetsang phallo ea tsona le viscosity.Sena se lumella hore ho be le taolo e ntlafetseng holim'a thepa nakong ea kopo, ho netefatsa hore e lumellana le sebōpeho se lakatsehang 'me e tlatsa li-voids ka katleho.

5. Matlafatso e Matlafalitsoeng:

• Karolo: Li-superplasticizers tsa polycarboxylate li kenya letsoho ho ntlafatseng ho khomarela pakeng tsa grout le substrate.Sena se bohlokoa bakeng sa ho netefatsa tlamo e matla le ho thibela litaba tse joalo ka debonding kapa delamination.

6. Ntlafatso ea Pele ea Matla:

• Karolo: Li-PCE li ka khothaletsa nts'etsopele ea matla a pele ho li-grouting mortars.Sena se na le thuso lits'ebetsong tseo ho tsona litlhophiso tse potlakileng le ho fumana matla li hlokahalang, joalo ka likarolo tsa konkreite kapa litokiso tsa sebopeho.

7. Ho lumellana le Li-additives:

• Karolo: Li-superplasticizers tsa polycarboxylate hangata li lumellana le li-additives tse ling tse atisang ho sebelisoa ha ho etsoa lirekere tsa grouting, tse kang li-accelerator tse behiloeng, li-retarders le li-air-entraining agents.Sena se lumella ho feto-fetoha ha maemo ho lokiseng thepa ea grout ho latela litlhoko tse khethehileng tsa morero.

8. Tšusumetso ea Moshoelella le e Tlase ea Tikoloho:

• Karolo: Li-PCE li tsebahala ka bokhoni ba tsona ba ho fokotsa metsi ha li ntse li boloka ts'ebetso.Sena se kenya letsoho mekhoeng ea kaho e tšoarellang le e baballang tikoloho ka ho fokotsa khabone ka kakaretso e amanang le tlhahiso le ho tsamaisa samente.

9. Phalleha e Phahameng ho Li-Grouts tsa Boiketlo:

• Karolo: Ho li-grouts tsa ho ikemela, li-superplasticizer tsa polycarboxylate li bohlokoa bakeng sa ho fihlela phallo e lakatsehang ntle le karohano.Sena se etsa bonnete ba hore grout e ikemela 'me e fana ka sebaka se boreleli, se lekanang.

10. Matla a Ntlafetseng:

Maikutlo:

• Tekanyo le Moralo oa Motsoako: Tekanyo e nepahetseng ea polycarboxylate superplasticizer e ipapisitse le moralo oa motsoako, mofuta oa samente le litlhoko tse ikhethang tsa projeke.Ho bohlokoa ho latela likhothaletso tsa moetsi.
• Teko ea Tumellano: Etsa liteko tsa tšebelisano ho netefatsa hore superplasticizer e lumellana le likarolo tse ling tsa motsoako oa grout, ho kenyeletsoa samente, li-additives le li-admixtures.
• Boleng ba Samente: Boleng ba samente e sebelisoang seretseng sa grouting bo ka ama ts'ebetso ea superplasticizer.Ho sebelisa samente ea boleng bo holimo ho bohlokoa bakeng sa ho fumana litholoana tse ntle.
• Maemo a Kopo: Nahana ka mocheso oa tikoloho, mongobo, le maemo a mang a tikoloho nakong ea ts'ebeliso ea seretse sa grouting ho netefatsa ts'ebetso e nepahetseng.

Ka kakaretso, li-superplasticizers tsa polycarboxylate li bapala karolo ea bohlokoa ho ntlafatseng ts'ebetso ea seretse sa grouting ka ho ntlafatsa ts'ebetso, ho fokotsa litaba tsa metsi, le ho khothaletsa ho khomarela hantle le nts'etsopele ea matla a pele.Tšebeliso ea bona e tlatsetsa katlehong le ts'ebetsong ea mekhoa ea ho haha.
