Yeyiphi indima edlalwa kwakhona kwiPowder yeRubber eDispersible kudaka olusekwe kwiGypsum?

Yiyiphi indima edlalwa kwakhona umgubo werabha werabha kwi-gypsum-based mortar?A: indima yokuchithwa kwakhona kwe-latex powder kwi-gypsum slurry emanzi: ukusebenza kwe-1 yokwakha;2 ukusebenza kokuhamba;3 i-thixotropy kunye ne-anti-sag;4 ukutshintsha ukuhambelana;5 yandisa ixesha elivulekileyo;6 ukomeleza ugcino lwamanzi.

Isiphumo seHigh Flexible Redispersible Powderemva kokunyangwa kwe-gypsum: i-1 yokwandisa amandla okuqina (i-adhesive eyongezelelweyo kwi-gypsum system);2 ukwandisa amandla okugoba;3 ukunciphisa imodyuli elastiki;4 ukwanda kokukhubazeka;5 ukwanda kwezinto eziphathekayo;I-6 yokuphucula ukuxhatshazwa kokugqoka, i-7 ukuphucula ukubambisana, i-8 ukunciphisa ukufakwa kwamanzi kwezinto eziphathekayo, i-9 ukwenza i-hydrophobic yezinto eziphathekayo (ukongeza i-hydrophobic rubber powder).

Zeziphi izinto zokuncamathelisa eziqhelekileyo zegypsum?

Impendulo: i-cellulose ether i-agent yokugcina amanzi inomsebenzi wokwandisa ukunamathela phakathi kwe-gypsum kunye nesiseko, njengesidingo sokudibanisa ibhodi ye-gypsum, ibhloko ye-gypsum, imigca yokuhlobisa i-gypsum ngaphezu kokongeza i-cellulose ether yokugcina amanzi, kufuneka kwakhona udibanise. ezinye i-organic adhesives, i-latex powder edibeneyo, i-polyvinyl alcohol rubber powder, i-carboxymethyl cellulose (CMC) , isitashi esilungisiweyo, i-polyvinyl acetate (iglue emhlophe), i-vinyl acetate-vinyl copolymer emulsion, njl.

Indlela yokukhetha i-adhesive ye-gypsum?

A: I-polyvinyl alcohol kunye ne-carboxymethyl cellulose ayinamanzi kangako, kodwa njengoko igypsum isetyenziswa kuphela ngaphakathi endlwini njengento yokuncamathelisa.I-Latex Powder enokuphinda ihlakazweIimfuno zokungangeni kwamanzi kunye nokuqina aziphezulu, ngoko ke ukonga ngakumbi ukusebenzisa i-polyvinyl alcohol kunye ne-carboxymethyl cellulose ukunyusa ukudibanisa.I-polyvinyl acetate kunye ne-vinyl acetate-vinyl copolymer emulsion ine-adhesion efanelekileyo, ukuxhathisa okulungileyo kwamanzi kunye nokuqina, kodwa inani le-polyvinyl alcohol likhulu kune-gypsum, kwaye ixabiso liphezulu.
