Isikhuthai-polycarboxylate superplasticizerkungathinta ikhwalithi yazo futhi, ezimweni ezimbi kakhulu, kuholele ezinkingeni zekhwalithi ephathekayo. Kunconywa izinyathelo ezilandelayo.

1. Khetha i-sodium gluconate yekhwalithi ephezulu njengengxenye ebuyisela emuva.

Njengamanje, kunenqwaba yabakhiqizi be-sodium gluconate emakethe. Abakhiqizi abanezinhlelo eziqinile zokulawula ukukhiqiza bangalawula ngempumelelo i-glucose eyinsalela kanye ne-Aspergillus niger ngesikhathi sokukhiqiza, ngaleyo ndlela behlise ubungozi bokonakala kuma-polycarboxylate superplasticizers akhiwe nge-sodium gluconate.

2. Engeza inani elifanelekile lesivikeli.

Ukwengeza inani elifanele lokulondolozwa ngesikhathi sokukhiqizwa kwe-polycarboxylate superplasticizer kungavimba ngempumelelo ukubola. Izilondolozi eziyinhloko okwamanje ezisemakethe zifaka i-sodium nitrite, i-sodium benzoate, ne-isothiazolinone. I-Isothiazolinone isetshenziswa kabanzi, iyasebenza kakhulu, futhi inobuthi obuphansi. Kuyi-fungicide engafaki oxidizing enobubanzi be-pH ebanzi, okuyenza ibe yinketho ekahle yokuvimbela kanye nokubulala amagciwane ama-superplasticizers. Umthamo ngu-0.5-1.5 kg ngethani le-polycarboxylate superplasticizer.

3. Naka indawo yokugcina impahla.

Gcina i-polycarboxylate superplasticizer endaweni epholile, enomoya omuhle kude nelanga eliqondile. Ukuhlolwa kwenziwa lapho ingxenye eyodwa ye-polycarboxylate superplasticizer yafakwa ebhodleleni elipholile, elivikela ilanga, kanti enye ingxenye yafakwa ebhodleleni elichayeke elangeni eliqondile. Ibhodlela elichayeke elangeni labumba ngokushesha futhi laba mnyama.

Futhi, iziqukathi ze-polycarboxylate superplasticizer zokugcina kufanele zenziwe ngezinto ezingezona ezensimbi, njengoba ukugqwala kwensimbi kungabangela ukuguquguquka ngisho nokuwohloka. Ngokwesibonelo, amathangi ensimbi engagqwali angabangela ukuthi i-superplasticizer ibe bomvu, amathange ensimbi angayibangela ibe luhlaza, futhi amathange ethusi angabangela ukuba ibe luhlaza okwesibhakabhaka.

4. Linganisa ngokunengqondo inani le-polycarboxylate superplasticizer elisetshenziswe kuphrojekthi.

Kwamanye amaphrojekthi, izinga lokusetshenziswa kwe-polycarboxylate superplasticizer ngokuvamile kunzima ukulilawula ngenxa yezinto ezifana nokuqhubeka kwephrojekthi kanye nezimo zezulu. Kwezinye izimo, i-polycarboxylate superplasticizer igcinwe esizeni isikhathi esingaphezu kwezinyanga ezintathu noma ngaphezulu, okuholela ekuwohlokeni okuvamile. Ngakho-ke, kunconywa ukuthi abakhiqizi baxhumane nomnyango wephrojekthi mayelana neshejuli yokusetshenziswa komkhiqizo kanye nomjikelezo ngaphambi kokulethwa, ukuqinisekisa ukusetshenziswa okuhleliwe kanye nebhalansi eguquguqukayo phakathi kokusetshenziswa kwe-polycarboxylate superplasticizer kanye nokugcwaliswa kabusha.

5. Yehlisa ukusetshenziswa kwezivimbelakuvunda ezifana ne-formaldehyde ne-nitrites.

Njengamanje, abanye abakhiqizi be-superplasticizer basebenzisa izilondolozi ezifana ne-formaldehyde, i-sodium benzoate, nama-nitrites ane-oxidizing. Nakuba zibiza kakhulu, lezi zivimbelakuvunda azisebenzi. Ngaphezu kwalokho, i-formaldehyde ingaphunyuka ngokuhamba kwesikhathi, izinga lokushisa, ne-pH, okubangela ukuthi umkhiqizo uqhubeke ukonakala. Kunconywa ukusebenzisa ama-biocides ekhwalithi ephezulu noma nini lapho kunokwenzeka. Emathangeni okugcina e-superplasticizer awonakele, wahlanze kahle ngaphambi kokuwagcwalisa nge-polycarboxylate superplasticizer entsha.

Ngaphezu kwalokho, ama-superplasticizers e-polycarboxylate anesikhunta esincane kakhulu, ukwelashwa kokushisa, ukungezwa kwe-hydrogen peroxide noma i-liquid caustic soda, noma ezinye izindlela zingasetshenziswa ukuze zisetshenziswe kabusha. Izincwadi ezifanele zibonisa ukuthi lezi zindlela zokwelapha zingabuyisela i-polycarboxylate superplasticizer esikhunjeni sayo sokuqala, zithole umbala ofana nowemikhiqizo engabunjiwe futhi ziqede iphunga.
