Thickener mhando uye hunhu
Cellulosic thickeners ane high thickening kunyatsoshanda, kunyanya pakukora kwechikamu chemvura; vane zvishoma zvipingamupinyi zvekugadzira zvipfeko uye zvinoshandiswa zvakanyanya; vanogona kushandiswa muhupamhi hwepH. Nekudaro, pane zvazvakaipira senge kusamira zvakanaka, kuwanda kupfachuka panguva yekupfeka roller, kusagadzikana kwakashata, uye kukonzeresa hutachiona. Nekuti ine yakaderera viscosity pasi pepamusoro shear uye yakakwira viscosity pasi pe static uye yakaderera shear, iyo viscosity inowedzera nekukurumidza mushure mekuputira, iyo inogona kudzivirira kudonha, asi kune rumwe rutivi, inokonzera kushata kwemazinga. Zvidzidzo zvakaratidza kuti sezvo huremu hwemamorekuru hweiyo thickener hunowedzera, kupfapfaidza kwepende yelatex kunowedzerawo. Cellulosic thickeners anowanzo kupfapfaidza nekuda kwehukuru hwawo hwemamorekuru. Uye nekuti cellulose yakawedzera hydrophilic, inoderedza kushomeka kwemvura kwefirimu repende.

Polyacrylic acid thickeners ane kusimba kwakasimba uye kuenzana zvivakwa, uye yakanaka kugadzikana kwebiological, asi inonzwira pH uye haina kushomeka kwemvura.

Iyo associative chimiro cheassociative polyurethane thickener inoparadzwa pasi pekuita kweshear force, uye viscosity inoderera. Apo simba rekuveura rinonyangarika, iyo viscosity inogona kudzorerwa, iyo inogona kudzivirira chiitiko che sag mubasa rekuvaka. Uye kudzoreredza kwayo viscosity kune imwe hysteresis, iyo inobatsira pakugadzika kweiyo firimu yekuputira. Hurukuro hwema molecular mass (zviuru kusvika kumakumi ezviuru) zve polyurethane thickeners yakadzikira zvakanyanya pane yakaenzana mamolecular mass (mazana ezviuru kusvika kumamiriyoni) emhando mbiri dzekutanga dzemakobvu, uye haizosimudziri kupfachuka. Polyurethane thickener molecules ane zvose hydrophilic uye hydrophobic mapoka, uye mapoka e-hydrophobic ane hukama hwakasimba nematrix yefirimu yekuputira, iyo inogona kuwedzera kumira kwemvura kwefirimu yekuputira.
