hlobopolycarboxylate superplasticizerli ka ama boleng ba tsona, 'me maemong a boima, li ka lebisa litabeng tsa boleng ba konkreite. Mehato e latelang e khothaletsoa.

1. Khetha sodium gluconate ea boleng bo holimo e le karolo e khutlisang morao.

Hajoale, ho na le bahlahisi ba bangata ba sodium gluconate 'marakeng. Baetsi ba nang le litsamaiso tse thata tsa taolo ea tlhahiso ba ka laola ka nepo tsoekere e setseng le Aspergillus niger nakong ea tlhahiso, ka hona ba fokotsa kotsi ea ho senyeha ho li-superplasticizers tsa polycarboxylate tse entsoeng ka sodium gluconate.

2. Eketsa tekanyo e loketseng ea li-preservative.

Ho eketsa palo e nepahetseng ea li-preservative nakong ea tlhahiso ea polycarboxylate superplasticizer ho ka thibela ho senyeha. Li-preservatives tsa mantlha tse 'marakeng hajoale li kenyelletsa sodium nitrite, sodium benzoate, le isothiazolinone. Isothiazolinone e sebelisoa haholo, e sebetsa haholo, ebile e na le chefo e tlase. Ke fungicide e sa tloseng oxidizing e nang le mefuta e mengata ea pH, e etsang hore e be khetho e nepahetseng bakeng sa ho thibela le ho thibela li-superplasticizers. Tekanyetso ke 0.5-1.5 kg ka tone ea polycarboxylate superplasticizer.

3. Ela hloko tikoloho ea polokelo.

Boloka polycarboxylate superplasticizer sebakeng se pholileng, se nang le moea o pholileng hole le khanya ea letsatsi. Ho ile ha etsoa teko eo ho eona karolo e 'ngoe ea polycarboxylate superplasticizer e neng e kenngoa ka har'a botlolo e pholileng, e sireletsang letsatsi, ha karolo e 'ngoe e ne e kenngoa ka botlolo e pepesehetseng letsatsi le tobileng. Botlolo e neng e pepeselitsoe letsatsing e ile ea bōptjoa ka potlako 'me ea fetoha e ntšo.

Hape, lijana tsa polokelo ea polycarboxylate superplasticizer li lokela ho etsoa ka thepa e seng ea tšepe, kaha kutu ea tšepe e ka baka ho fifala esita le ho senyeha. Ka mohlala, litanka tsa tšepe tse sa hloekang li ka etsa hore superplasticizer e be khubelu, litanka tsa tšepe li ka etsa hore e be tala, 'me litanka tsa koporo li ka etsa hore e be putsoa.

4. Hakanya ka mokhoa o utloahalang palo ea polycarboxylate superplasticizer e sebelisitsoeng morerong ona.

Mererong e meng, sekhahla sa ts'ebeliso ea polycarboxylate superplasticizer hangata ho thata ho e laola ka lebaka la lintlha tse kang tsoelo-pele ea projeke le maemo a leholimo. Maemong a mang, polycarboxylate superplasticizer e bolokiloe setšeng nako e fetang likhoeli tse tharo kapa ho feta, e lebisang ho senyeha khafetsa. Ka hona, ho khothaletsoa hore bahlahisi ba buisane le lefapha la projeke mabapi le kemiso ea tšebeliso ea sehlahisoa le potoloho pele se tlisoa, ho netefatsa ts'ebeliso e reriloeng le tekano e matla lipakeng tsa tšebeliso ea polycarboxylate superplasticizer le ho e tlatsa.

5. Fokotsa tšebeliso ea li-preservatives tse kang formaldehyde le nitrites.

Hajoale, bahlahisi ba bang ba li-superplasticizer ba sebelisa li-preservatives tse kang formaldehyde, sodium benzoate, le nitrite e matlafatsang oxidizing. Le hoja e le litšenyehelo, li-preservative tsena ha li sebetse. Ho feta moo, formaldehyde e ka baleha ha nako e ntse e feta, mocheso le pH, e leng ho etsang hore sehlahisoa se tsoele pele ho senyeha. Ho khothalletsoa ho sebelisa li-biocide tsa boleng bo holimo neng kapa neng ha ho khoneha. Bakeng sa litanka tsa polokelo ea li-superplasticizer tse senyehileng, li hloekise hantle pele u li tlatsa ka polycarboxylate superplasticizer e ncha.

Ho phaella moo, bakeng sa li-superplasticizers tsa polycarboxylate tse nang le hlobo e fokolang haholo, phekolo ea mocheso, ho eketsoa ha hydrogen peroxide kapa soda ea caustic soda, kapa mekhoa e meng e ka sebelisoa ho e sebelisa hape. Lingoliloeng tse amehang li bontša hore mekhoa ena ea phekolo e ka tsosolosa moldy polycarboxylate superplasticizer ho thepa ea eona ea pele, ho finyella 'mala o tšoanang le oa lihlahisoa tse sa tsitsang le ho felisa monko o monate.
