Teach you how to choose hydroxypropyl methyl cellulose viscosity?

Many mortar, putty powder enterprises will use hydroxypropyl methyl cellulose this chemical raw materials, some enterprises on the selection of which viscosity of hydroxypropyl methyl cellulose is not very clear, hydroxypropyl methyl cellulose has 4W-5W low viscosity of hydroxypropyl methyl cellulose, also have 10W, 15W, 20W high viscosity of hydroxypropyl methyl cellulose. Here is how to choose hydroxypropyl methyl cellulose from various industries.

01 Cement mortar

Cement mortar to choose 10W-20W viscosity of hydroxypropyl methyl cellulose, this viscosity of hydroxypropyl methyl cellulose can be used as water retention agent, retarding agent so that the mortar has pumping property, can make cement mortar daub will not dry too fast and crack, increase the strength after hardening.

02 putty powder

Putty powder to choose 10W of hydroxypropyl methyl cellulose, water retention is good low viscosity can also. This viscosity of hydroxypropyl methyl cellulose in the putty is mainly from water retention, bonding and lubrication, to avoid the crack and dehydration phenomenon caused by too fast water loss, and enhance the adhesion of the putty, reduce the construction flow hanging phenomenon, the construction is smooth.

03 ceramic tile binder

The brick binder should be hydroxypropyl methyl cellulose with 10W viscosity. This viscosity of hydroxypropyl methyl cellulose can significantly improve the adhesive strength of ceramic tile binder, water retention increase construction cycle, delicate, uniform, convenient construction, and has good moisture resistance.

04 glue

107 glue and 108 glue to use 10W viscosity instant hydroxypropyl methyl cellulose. Hydroxypropyl methyl cellulose can make glue with thickening and water retention, enhance the construction.
