Ni uruhe ruhare ifu ya reberi isubirwamo igira uruhare muri minisiteri ishingiye kuri gypsumu? Igisubizo: uruhare rwongeye gutatanya ifu ya latx mumazi ya gypsumu itose: imikorere yubwubatsi 1; Imikorere 2; 3 thixotropy na anti-sag; 4 guhindura ubumwe; 5 kongerera igihe cyo gufungura; 6 kongera amazi.
Ingaruka yaIfu ihindagurika cyanenyuma yo gukira gypsumu: 1 kongera imbaraga zingutu (adhesive yongeyeho muri sisitemu ya gypsumu); 2 kongera imbaraga zo kunama; Kugabanya modulus yoroheje; 4 kongera ubumuga; 5 kongera ubwinshi bwibintu; 6 kunoza imyambarire, 7 kunoza ubumwe, 8 kugabanya kwinjiza amazi, 9 gukora hydrophobique (kongeramo ifu ya hydrophobique).
Ni ubuhe butumwa busanzwe bwa gypsumu?
Igisubizo: selulose ether igumana amazi ifite umurimo wo kongera guhuza hagati ya gypsumu na base, nko gukenera guhuza ikibaho cya gypsum, blok ya gypsum, imirongo ishushanya ya gypsumu usibye kongeramo selile ya ether igumana amazi, ugomba no kongeramo amavuta amwe n'amwe, ifu ya latx ikwirakwizwa, ifu ya polyvinyl inzoga ya rubber, carboxymethyl selulose (CMC), ibinyamisogwe byahinduwe, acetate polyvinyl (glue yera), vinyl acetate-vinyl copolymer emulsion, nibindi.
Nigute ushobora guhitamo ibifatika bya gypsumu?
Igisubizo: inzoga za polyvinyl na carboxymethyl selulose ntizirinda amazi, ariko nka gypsumu ikoreshwa mumazu gusa nk'ifata,Ifu ya Latexibisabwa kugirango birinde amazi kandi biramba ntabwo biri hejuru, nibyiza rero gukoresha inzoga za polyvinyl na carboxymethyl selulose kugirango wongere umubano. Acetate ya polyvinyl na vinyl acetate-vinyl copolymer emulsion ifite adhesion nziza, irwanya amazi meza kandi iramba, ariko ingano ya alcool ya polyvinyl nini kuruta iyo gypsumu, kandi igiciro kiri hejuru.
