1.Muyero wepolycarboxylate superplasticizer yekudzikisa mvura mumiririri wakakura kwazvo, uye kune mabhubhu akawandisa pamusoro peiyo kongiri chimiro.
Kubva pakuona kwekupomba uye kusimba, zvinobatsira kuwedzera zvakakodzera mhepo-inopinza zvinhu. Mazhinji emapolycarboxylate ekudzikisa mvura ane mhepo-inopinza zvivakwa. Polycarboxylic acid-yakavakirwa mvura-inoderedza admixtures zvakare ine saturation point senge naphthalene-yakavakirwa mvura-inoderedza admixtures. Kune marudzi akasiyana esimende uye akasiyana simenti dosages, saturation mapoinzi eiyi admixture mukongiri akasiyana. Kana huwandu hwekusanganiswa huri pedyo nekuzara kwayo, iyo fluidity yemusanganiswa wekongiri inogona kuvandudzwa chete nekugadzirisa huwandu hweslurry mukrete kana kushandisa dzimwe nzira.
Phenomenon: Imwe chiteshi chekusanganisa yanga ichishandisa polycarboxylic acid-yakavakirwa mvura-inoderedza mumiriri kugadzira kongiri kwenguva yakati. Kamwe kamwe rimwe zuva, imwe nzvimbo yekuvaka yakashuma kuti mushure mekubvisa chimiro chemudhuri wekucheka, zvakaonekwa kuti pakanga pane mafuru akawandisa pamusoro pemadziro uye chitarisiko chaive chakashata zvakanyanya.
Chikonzero: Pazuva rokudira kongiri, nzvimbo yokuvaka yakashuma kakawanda kuti kudonha kwakanga kuri kuduku uye mvura yakanga isina kunaka. Vashandi vari pabasa murabhoritari yekongiri yekusanganisa chiteshi vakawedzera huwandu hwemisanganiswa. Nzvimbo yekuvaka yakashandisa simbi yakakura yakaita fomu, uye zvinhu zvakawandisa zvaiwedzerwa panguva imwe panguva yekudururwa, zvichikonzera kuzunguzika kusina kuenzana.
Kudzivirira: Simbisa kutaurirana nenzvimbo yekuvaka, uye kurudzira kuti kureba kwekudyisa uye nzira yekuzunguza zvishandiswe zvakanyatsoenderana nezvinodiwa. Kuvandudza mvura yemusanganiswa wekongiri nekugadzirisa huwandu hweslurry mukrete kana kushandisa dzimwe nzira.
2.Polycarboxylate mvura-inoderedza mumiririri yakanyanyisa-yakasanganiswa uye nguva yekuisa yakawedzerwa.
Chiitiko:Kudonha kwekongiri kwakakura, uye zvinotora maawa makumi maviri nemana kuti kongiri igadzike. Pane imwe nzvimbo yekuvaka, maawa 15 mushure mekugadzira dandakongiri yakadururwa, yakashumwa kuchiteshi chokuvhenganisa kuti chikamu chekongiri chakanga chisati chasimbiswa. Nzvimbo yekuvhenganisa yakatumira mainjiniya kuti atarise, uye mushure mekupisa kurapwa, kusimba kwekupedzisira kwakatora maawa makumi maviri nemana.
Chikonzero:Kuwanda kwezera rekudzikisa mvurant yakakura, uye tembiricha yakadzikama husiku, saka kongiri ye hydration inononoka. Vashandi vanoburutsa panzvimbo yekuvaka vanowedzera mvura pachivande kune kongiri, iyo inopedza mvura yakawanda.
Kudzivirira:Huwandu hwemusanganiswa shzvingave zvakakodzera uye kuyerwa kunofanira kuva kwakarurama. Tinokuyeuchidza kuti uteerere kuvharidzira uye kugadzirisa kana tembiricha panzvimbo yekuvaka yadzikira, uye polycarboxylic acid admixtures inonzwa kudyiwa kwemvura, saka usawedzera mvura paunoda.
