He aha ke kuleana o ka pauka lāʻau redispersible i loko o ka gypsum-based mortar?A: ke kuleana o ka pauka latex re-dispersible i loko o ka gypsum slurry pulu: 1 hana hana;2 kahe hana;3 thixotropy a me ka anti-sag;4 hoʻololi i ka pilina;5 hoʻonui i ka manawa wehe;6 hoʻonui i ka mālama ʻana i ka wai.
Ka hopena oKiʻekiʻe Flexible Redispersible paudama hope o ka mālama ʻana i ka gypsum: 1 ka hoʻonui ʻana i ka ikaika tensile (hoʻopili hou i ka ʻōnaehana gypsum);2 ka hoʻonui ʻana i ka ikaika kulou;3 hoemi ana i ka elastic modulus;4 hoʻonui deformability;5 e hoʻonui ana i ka nui o nā mea;6 e hoʻomaikaʻi i ka pale ʻana i ka ʻaʻahu, 7 e hoʻomaikaʻi i ka cohesion, 8 e hōʻemi i ka lawe ʻana o ka wai o ka mea, 9 e hana i ka mea hydrophobic (hoʻohui i ka pauka hydrophobic rubber).
He aha nā gypsum adhesive maʻamau?
Pane: ʻo ka cellulose ether wai ka mea mālama i ka hana o ka hoʻonui ʻana i ka adhesion ma waena o ka gypsum a me ke kumu, e like me ka pono e hoʻopaʻa i ka papa gypsum, gypsum block, gypsum decorative lines i ka hoʻohui ʻana i ka cellulose ether wai-paʻa ʻana, pono ʻoe e hoʻohui. kekahi mau mea hoʻopili kūlohelohe, pauka latex dispersible, polyvinyl alcohol rubber pauka, carboxymethyl cellulose (CMC), starch i hoʻololi ʻia, polyvinyl acetate (keʻokeʻo glue), vinyl acetate-vinyl copolymer emulsion, etc.
Pehea e koho ai i ka mea hoʻopili no ka gypsum?
A: polyvinyl alcohol a me carboxymethyl cellulose ʻaʻole liʻiliʻi ka wai, akā no ka mea, hoʻohana ʻia ka gypsum i loko o ka hale ma ke ʻano he mea hoʻopili.Pahu Latex Hiki HouʻAʻole kiʻekiʻe nā koi no ka wai a me ka lōʻihi, no laila ʻoi aku ka maikaʻi o ka hoʻohana ʻana i ka waiʻona polyvinyl a me ka carboxymethyl cellulose e hoʻonui i ka pilina.ʻO ka polyvinyl acetate a me ka vinyl acetate-vinyl copolymer emulsion he hoʻopili maikaʻi, kūpaʻa wai maikaʻi a me ka lōʻihi, akā ʻoi aku ka nui o ka polyvinyl alcohol ma mua o ka gypsum, a ʻoi aku ke kumukūʻai.
