He aha te mahi a te paura rapa redispersible i roto i te moata gypsum-based? A: te mahi o te paura taherapa re-dispersible i roto i te slurry gypsum maku: 1 mahi hanga; 2 mahi rere; 3 thixotropy me te anti-sag; 4 huri i te whakakotahitanga; 5 whakaroa te wa tuwhera; 6 whakarei ake te pupuri wai.
Te painga oHigh Flexible Redispersible Paurai muri i te rongoa gypsum: 1 te whakanui ake i te kaha tensile (te taapiri taapiri i roto i te punaha gypsum); 2 te whakanui ake i te kaha piko; 3 te whakaheke i te waahanga rapa; 4 te whakanui ake i te deformability; 5 te whakanui ake i te kiato rauemi; 6 ki te whakapai ake i te mau kakahu, 7 ki te pai ake te whakakotahitanga, 8 ki te whakaiti i te whakauru wai o te rauemi, 9 ki te hanga i te rauemi hydrophobic (whakapiri hydrophobic rapa paura) .
He aha nga taapiri gypsum noa?
Whakautu: ko te kaihoko pupuri wai cellulose ether te mahi o te whakanui ake i te piri i waenga i te gypsum me te turanga, penei me herea te papa gypsum, poraka gypsum, raina whakapaipai gypsum hei taapiri atu ki te taapiri i te kaihoko pupuri wai cellulose ether, me taapiri ano koe etahi whakapiri waro, paura taherapa marara, polyvinyl waipiro rapa paura, carboxymethyl cellulose (CMC) , māngaro whakarerekē, polyvinyl acetate (kāpia ma), vinyl acetate-vinyl copolymer emulsion, etc.
Me pehea te whiriwhiri i te whakapiri mo te gypsum?
A: Ko te waipiro polyvinyl me te carboxymethyl cellulose he iti ake te parewai, engari i te mea ka whakamahia noa te gypsum i roto i te whare hei whakapiri,Te paura taherapa tukuruaKo nga whakaritenga mo te parewai me te mauroa kaore i te teitei, no reira he pai ake te whakamahi i te waipiro polyvinyl me te carboxymethyl cellulose hei whakanui ake i te hononga. Ko te polyvinyl acetate me te vinyl acetate-vinyl copolymer emulsion he pai te piri, te pai o te wai me te roa, engari ko te nui o te waipiro polyvinyl he nui atu i te gypsum, a, he nui ake te utu.
