Starch ether is one of the polysaccharide compounds which is extracted from natural plants. This ether owns a nearly same kind of chemical structure like the cellulose ether. Coming to the physical properties of starch ether, they act similar to the other kinds of either. The starch ether is easily soluble in water, especially cold water.
The usual size of the particles ranges greater than equal to ninety-eight percent or more precisely, eighty mesh sieve. Coming to the viscosity of starch ether, it ranges between three hundred to eight hundred CPS. The moisture content of these ether is usually equal to or less than ten percent. Starch ether owns a typical white or little yellow colour shade.
Where is it used?
Starch ether is used to build mortar. It is because it has a significant property which helps in increasing the consistency of mortar. It also plays a major role in improving the performance of the construction. It is generally used at the conjunction point where nonmodified and modified cellulose ethereal are joined.
The ether can be used for both neutral as well as alkaline system. It is also compatible for use with additives in the mixture of gypsum and cement product. It can also be used with additives like surfactants and other such water-soluble polymers.
This ether is usually used for either hand spraying or spraying mortar using a machine. Other than mortar, several other caulking material and masonry adhesives are sprayed with ether to form a perfect mixture of cement and gypsum.
What is hydroxypropyl starch ether?
Hydroxypropyl starch ether is one of the others which impart unique properties to the products made up of cement or gypsum. The chemical structure of this ether stands quite similar to the structure of hydroxypropyl methylcellulose.
It serves as a good quality HPMC and also owns good comparability with the different types of building additives the starch ether is actually used with the cement based mixtures in order to thicken the mixture and increase its resistance towards cracking. In short, the addition of either allows better workability and a significant drop in the cost of formulating mortar.
Properties of starch ether:-
As per the HPS Manufacturers of Shijiazhuang, this ether owns a special chemical structure, it prevents hanging phenomenon of the thick layers of mortar. Apart from hanging, it also helps in avoiding another such unfavourable phenomenons.
Addition of appropriate amounts of hydroxypropyl starch ether in the mixture or mortar causes a delay in the opening time served by it. The process of water retention can be kept stable by adding starch ether too. Moreover, it has helped in better retention compared to the water retaining the capacity of the common agents.
There are a number of HPS suppliers in China who sell best quality starch ether having fast thickening function for the mortars. The ether helps in enhancing the archeology of the various types of mortar too. Moreover, this ether can be used for effective prevention of the mortar from harsh external chemical reactions too.
