HPMC vandretention
HPMC-vandretention er en ikke-ionisk celluloseether. I cementmørtel og gipsbaseret opslæmning spiller det hovedsageligt en rolle som vandretention og fortykkelse, hvilket effektivt kan forbedre opslæmningens vedhæftning og sagmodstand. Det er et uundværligt tilsætningsstof i mørtel og pasta. HPMC vandretention produceret af Milestone Industrial Co. Ltd. har høj renhed og god kvalitet. Det har fremragende vandretention og fortykningsegenskaber, når det bruges i mørtel og gips. Det er det første valg for celluloseethere i din byggebranche.

Produkt beskrivelse
HPMC vandretention
HPMC vandretention is a non-ionic cellulose ether. In cement mortar and gypsum-based slurry, it mainly plays a role of water retention and thickening, which can effectively improve the adhesion and sag resistance of the slurry. It is an indispensable additive in mortar and paste. HPMC vandretention produced by Milestone Industrial Co. Ltd. has high purity and good quality. It has excellent water retention and thickening properties when used in mortar and gypsum. It is the first choice for cellulose ethers in your construction industry.

Er vandretentionskapaciteten og mængden af HPMC vandretention påvirket af sæsonen?
1) Since air temperature, wind pressure and other factors will affect the volatilization rate of water in cement mortar and gypsum-based products, there are some differences in the water retention effect of the same amount of HPMC vandretention in different seasons.
2) I forskellige årstider kan opslæmningens vandretentionseffekt justeres ved at øge eller mindske mængden af HPMC-vandretention under specifik konstruktion. Fremme mørtel og gips for at vise forskellig vandretention.

Ydelsen i specifikke operationer er som følger:
If you want to achieve the water retention effect during the high temperature summer construction, you need to add high-quality HPMC water retention in sufficient quantities according to the formula, so that the water will not lose too fast during the operation; if you do not add high-quality HPMC vandretention, the high temperature The operation will have quality problems such as insufficient hydration, reduced strength, cracking, hollowing and falling off caused by excessive drying, and it will also increase the difficulty of construction for workers.
If under non-summer and non-high temperature conditions, as the temperature drops, the amount of HPMC vandretention can be gradually reduced, so that the same water retention effect can be achieved.
