He aha te mahi a te paura rapa Redispersible i roto i te moata-a-Gypsum?

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 hei whakapai ake i te mau kakahu, 7 hei whakapai ake i te whakakotahitanga, 8 hei whakaiti i te whakaurunga wai o te rauemi, 9 hei hanga i te rauemi hydrophobic (te taapiri i te paura rapa hydrophobic) .

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.
