Ndeipi basa rinoitwa redispersible rubber poda mu gypsum-based mortar?A: basa re-dispersible latex powder mune wet gypsum slurry: 1 kuvaka kwekuita;2 kuyerera kwekuita;3 thixotropy uye anti-sag;4 shandura kubatana;5 kuwedzera nguva yakazaruka;6 kuwedzera kuchengetwa kwemvura.
Mhedzisiro yeHigh Flexible Redispersible Powdermushure mekurapa gypsum: 1 kuwedzera simba rekusimba (yakawedzera adhesive mugypsum system);2 kuwedzera simba rekukotama;3 inoderera elastic modulus;4 kuwedzera deformability;5 kuwedzera zvinhu density;6 yekuvandudza kupfeka kuramba, 7 kuvandudza kubatana, 8 kuderedza kunyura kwemvura, 9 kugadzira iyo hydrophobic (kuwedzera hydrophobic rubber powder).
Ndezvipi zvakajairika gypsum adhesives?
Mhinduro: cellulose ether mvura-inochengetedza mumiriri ine basa rekuwedzera adhesion pakati pegypsum uye chigadziko, sekuda kusungirira gypsum board, gypsum block, gypsum yekushongedza mitsara mukuwedzera kuwedzera cellulose ether inochengetedza mvura, iwe unofanirwawo kuwedzera. mamwe organic adhesives, dispersible latex powder, polyvinyl alcohol rubber powder, carboxymethyl cellulose (CMC), modified starch, polyvinyl acetate (white glue), vinyl acetate-vinyl copolymer emulsion, nezvimwewo.
Nzira yekusarudza adhesive ye gypsum?
A: polyvinyl doro uye carboxymethyl cellulose haina kudzivirira mvura, asi sezvo gypsum inongoshandiswa mukati meimba seanonamira, iyoRedispersible Latex Powderzvinodiwa zvekusapinda mvura uye kusimba hazvina kukwirira, saka zvine mari yakawanda kushandisa polyvinyl doro uye carboxymethyl cellulose kuwedzera kubatana.Iyo polyvinyl acetate uye vinyl acetate-vinyl copolymer emulsion ine yakanaka adhesion, yakanaka kudzivirira mvura uye kusimba, asi huwandu hwepolyvinyl doro hwakakura kupfuura iyo yegypsum, uye mutengo wakakwira.
