2. Kana yakashandiswa pamwe chete nemamwe marudzi emvura inoderedza vamiririri, hapana maitiro epamusoro.

Munguva yakapfuura, pakugadzira kongiri, rudzi rwepombi yemushonga waigona kuchinjwa pamadiro, uye zvinhu zvemusanganiswa wekongiri hazvizove zvakasiyana zvakanyanya nemigumisiro yerabhoritari, uye kwaisazova nekushanduka kamwe kamwe kwezvinhu zvemusanganiswa wekongiri. .

Kana polycarboxylic acid-based-based-water-reducing agents inoshandiswa pamwe chete nemamwe marudzi emvura-inodzikisa mvura, zvakaoma kuwana superimposed effects, uye mutual solubility pakati pepolycarboxylic acid-based-based water-reducing agent solutions nemamwe marudzi emvura- kuderedza agent solutions ihwo hurombo.

3. Hapana chekugadzirisa mhedzisiro mushure mekuwedzera zvinowanzoshandiswa kushandura zvikamu.

Parizvino, kune mari shoma mukutsvaga kwesainzi pane polycarboxylic acid-based-water-reducing agents. Muzviitiko zvakawanda, chinangwa chekutsvaga kwesainzi ndechekuwedzera kuvandudza kwayo plasticizing uye kuderedza mvura. Zvakaoma kugadzira mamorekuru zvimiro zvinoenderana neakasiyana einjiniya zvinodiwa. Nhevedzano yepolycarboxylic acid-yakavakirwa mvura yekudzikisa maajenti ane akasiyana ekudzoreredza uye kukurumidza mhedzisiro, hapana mhepo-inopinza kana akasiyana mhepo-intraining zvivakwa, uye akasiyana viscosities anogadzirwa. Nekuda kwekusiyana uye kusagadzikana kwesimende, musanganiswa, uye akaunganidzwa mumapurojekiti, zvakakosha kuti vanogadzira musanganiswa uye vatengesi vaunganidze uye vagadzirise polycarboxylate inoderedza mvura-inoderedza zvigadzirwa zvinoenderana nezvinodiwa zveprojekiti.

Parizvino, matanho ehunyanzvi ekugadziriswa kwekomboni yevashandi vanodzikisa mvura anonyanya kubva pamatanho ekugadzirisa echinyakare-anoderedza mvura maajenti akadai se lignosulfonate series uye naphthalene series high-effect-effect-reducation agents. Miedzo yakaratidza kuti yakapfuura gadziriso tekinoroji matanho haakodzeri kune polycarboxylic acid-yakavakirwa mvura yekudzikisa maajenti. Semuenzaniso, pakati pezvikamu zvakasara zvinoshandiswa kugadzirisa naphthalene-based-water-reducing agents, sodium citrate haina kukodzera polycarboxylic acid-based-water-reducing agents. Kwete chete iyo haina kudzoreredza, inogona kukurumidza coagulation, uye sodium citrate mhinduro Iyo miscibility ne polycarboxylic acid-based-water reduction agents zvakare yakashata kwazvo.

Uyezve, marudzi mazhinji eanosvibisa maajenti, air-entraining agents uye thickeners haana kukodzera polycarboxylic acid-based water reduction agents. Kuburikidza nemiedzo uye ongororo iri pamusoro, hazvina kuoma kuona kuti nekuda kwekunyanya kweiyo molecular chimiro chepolycarboxylic acid-yakavakirwa mvura yekudzikisa maajenti, zvichibva pahupamhi hwekutsvagisa kwesainzi uye kuunganidzwa kweinjiniya yekushandisa chiitiko panguva ino, kukanganisa kwacho. yepolycarboxylic acid inoderedza mvura maajenti pa polycarboxylic acid-based superplasticizers kuburikidza nezvimwe zvinoumba makemikari Hapana nzira dzakawanda dzekugadzirisa zvinoderedza mvura, uye nekuda kwedzidziso uye. zviyero zvakamiswa kare zvekugadzirisa mamwe marudzi evamiririri vanoderedza mvura, kuongorora kwakadzama uye tsvakurudzo inogona kudiwa kune polycarboxylate-based based-reducation agents. Gadzirisa uye wedzera.

4. Kugadzikana kwekuita kwechigadzirwa kwakanyanyisa.

Haasi mazhinji makambani ekongiri anodzikisa mvura agent synthesis anogona kunyatso kutorwa semakambani akanaka emakemikari. Makambani mazhinji anongogara ari mudanho rekutanga rekugadzira remusanganisi nemichina yekurongedza, uye mhando yechigadzirwa inoganhurwa nemhando ye masterbatch. Panyaya yekutonga kwekugadzira, kusagadzikana kweiyo sosi uye mhando yezvigadzirwa zvakagara zviri chinhu chikuru chinotambudza kuita kwepolycarboxylic acid-based superplasticizers.
