Crasso effectus hydroxypropyl methylcellosus

Hydroxypropyl methylcellulose editibus humidum cæmento cum optimum viscositas, quae potest significantly auget adhaesionem inter infectum cæmento et basi layer et amplio anti-sagax perficientur de cæmento. In cæmento. The thickening effect of cellulose ether can also increase the homogeneity and anti-dispersion ability of fresh cement-based materials, prevent delamination, segregation and bleeding of mortar and concrete, and can be used in fiber-reinforced concrete, underwater concrete and self-compacting concrete .

Hydroxypropyl methylcellosus crescit viscositas cement-fundatur materiae ex viscosity cellulosa aethere solution. Viscositas Cellulose aether solutio est plerumque aestimari a indice "viscositas." Viscositas Cellulose Aether refers to the certa concentratione (ut II%) de Cellulose aether solutio ad certum temperatus (ut a a certa mensurae instrumentum (ut rupe (vel gyrationis rate, ut XX RPM).

Viscositas est momenti parametri ad aestimare ad perficientur de Cellulose aether. The higher the viscosity of hydroxypropyl methylcellulose solution, the better the viscosity of the cement-based material, the better the adhesion to the substrate, the better the anti-sagging and anti-dispersing ability. Fortis, si autem eius viscositas est magna, quod erit afficit fluiditatem et operability cement-fundatur materiae (ut haerentem holocaustum cultris per emplastring cæmento). Ideo in viscositas Cellulose aethere in sicco-mixta cæmento plerumque 15,000 ~ 60.000 MPA. S-I, auto-adtritio cæmento quod auto-compacting concretum quod eget superior fluidos eget inferioribus viscosity of Cellulose aether.

Praeterea, crasso effectus hydroxypropyl methylcellosus auget aquae demanda cemento-fundatur materiae, ita augendae cedat cæmento.

Et Viscosity de hydroxypropyl Methylcellulose solutio pendent in his factoribus:

Cellulosose Aether Molecular pondus (vel gradu polymerization) et concentration, solution temperatus, tondendas rate et test modi.

I. De altiorem gradum polymerization de cellulosose aether, maior est molecularium pondus, et altior viscositas aqueum solution;

2. The higher the dosage (or concentration) of cellulose ether, the higher the viscosity of its aqueous solution, but attention should be paid to selecting the appropriate dosage when using it, so as to avoid excessive dosage and affect the working performance of mortar and concrete;

III. Sicut pleraque liquida, in viscositas cellulosis aether solution et decrescet cum incremento temperatus et altior concentratio de Cellulose aether, maior effectus temperatus;

IV. Cellulose aether solutions sunt plerumque pseudoplasticas cum tondendas extenuantibus proprietatibus. In altiorem ad tondendas rate per test, in inferioribus viscositas.

Ergo cohaesionis cæmento erit redigetur ex actione externa vis, quod est utile ad radping constructione cæmento, ut cæmento potest habere bonum workability et cohaesionis simul. Tamen, cum concentratio de Cellulose aether solution est valde humilis et viscititas est valde parvum, et ostendam in characteres Newtonian fluidi. Cum concentration crescit, solutio paulatim ostendere characteres pseudoplastic fluidi, et altius concentration, magis obvious pseudoplasticitas.
