Iyiphi indima edlalwa kabusha impushana yerabha ehlakazeka odakeni olususelwa ku-gypsum? A: indima ye-latex powder ehlakazeka kabusha ku-gypsum slurry emanzi: ukusebenza kwe-1 yokwakha; 2 ukusebenza kokugeleza; I-3 thixotropy kanye ne-anti-sag; 4 shintsha ukubumbana; 5 yandisa isikhathi sokuvula; 6 thuthukisa ukugcinwa kwamanzi.
Umphumela weI-High Flexible Redispersible Powderemva kokwelashwa kwe-gypsum: i-1 ekhulayo amandla okuqina (i-adhesive eyengeziwe ohlelweni lwe-gypsum); 2 ukwandisa amandla okugoba; 3 ukuncipha kwe-elastic modulus; 4 ukukhubazeka okwandayo; 5 ukwandisa ukuminyana kwezinto ezibonakalayo; 6 ukuthuthukisa ukumelana nokugqoka, i-7 ukuthuthukisa ukubumbana, i-8 ukunciphisa ukumuncwa kwamanzi kwento, 9 ukwenza i-hydrophobic impahla (ukwengeza i-hydrophobic rubber powder) .
Yiziphi izinamathiselo ezijwayelekile ze-gypsum?
Impendulo: i-cellulose ether egcina amanzi ejenti inomsebenzi wokwandisa ukunamathela phakathi kwe-gypsum nesisekelo, njengesidingo sokuhlanganisa ibhodi le-gypsum, i-gypsum block, imigqa yokuhlobisa ye-gypsum ngaphezu kokwengeza i-ejenti yokugcina amanzi ye-cellulose ether, udinga futhi ukwengeza ezinye izinamathiselo eziphilayo, i-latex powder ehlakazekayo, i-polyvinyl alcohol rubber powder, i-carboxymethyl cellulose (CMC), isitashi esilungisiwe, i-polyvinyl acetate (iglue emhlophe), i-vinyl acetate-vinyl copolymer emulsion, njll.
Ungakhetha kanjani i-adhesive ye-gypsum?
A: I-polyvinyl alcohol kanye ne-carboxymethyl cellulose azikwazi ukungena emanzini, kodwa njengoba i-gypsum isetshenziswa endlini kuphela njengento yokunamathisela,I-Latex Powder ehlakazeka kabushaIzidingo zokungangeni kwamanzi nokuqina aziphezulu, ngakho-ke ukonga kakhulu ukusebenzisa i-polyvinyl alcohol ne-carboxymethyl cellulose ukuze kwandiswe isibopho. I-polyvinyl acetate ne-vinyl acetate-vinyl copolymer emulsion inokunamathela okuhle, ukumelana namanzi okuhle nokuqina, kodwa inani le-polyvinyl alcohol likhulu kunelo le-gypsum, futhi intengo iphakeme.
