1) Wall structure of natural granite and marble plates. Natural stone is heavier. In order to ensure safety, double insurance is adopted. That is, the plate and the base layer are tied with copper wire, and then the cement mortar is poured. The facing plate is separated from the structural wall by 3-5cm, and it is used as a grouting joint. The height of each filling is about 20cm, and the infusion is continued after solidification.
2) Construction technology of natural granite and marble sheet wall surface. Base treatment - installation of base steel mesh - sheet drilling - lashing sheet - grouting - caulking - polishing.
(2) Bluestone slab wall structure and construction technology
The bluestone slab wall structure and construction process can be pasted in a similar way to glazed tiles. The bluestone plate has a high water absorption rate and is saturated with water before application.
When using small-sized stone and artificial stone in the local decoration, you can refer to the glazed tile attachment method.
Alpha Cyclodextrin sulfate & Hydrocortisone phosphate
Alpha-Cyclodextrin (synonyms: cyclohexaamylose, cyclomaltohexaose, alpha-Schar-dinger dextrin) is a non-reducing cyclic saccharide comprised of six glucose units linked by alpha-1, 4 bonds.
It is produced by the action of cyclodextrin glucosyltransferase (CGTase, EC 2.4.1.19) on hydrolysed starch syrups at neutral pH (6.0–7.0) and moderate temperature (35–40°C).
The annular (or doughnut-shaped) structure of alpha-cyclodextrin provides a hydrophobic cavity that allows formation of inclusion complexes with a variety of non-polar organic molecules of appropriate size.
The hydrophilic nature of the outer surface of the cyclic structure makes alpha-cyclodextrin water-soluble.

Gamma-cyclodextrin is a ring-shaped molecule made up of eight glucose units linked by alpha-1,4-bonds. The solubility degree of gamma-cyclodextrin in water is 23.2 g/100ml @ 25°C, which is higher than alpha-cyclodextrin and beta-cyclodextrin, and it is used to allow formation of inclusion complexes with bigger molecules.
CAS No.: 17465-86-0
Molecular Formula: C48H80O40
Molecular Weight: 1297.12
Application:
Gamma-cyclodextrin can be used as a carrier for flavours, sweeteners, and colours. In chemistry it is a valuable chemical reagent. When gamma-cyclodextrin exists, fluorescence intensity of fluorescence pigment will become much bigger, so it is used as the analysis of protein and amino acid. Gamma-cyclodextrin is also used to separate long-chain organic compound, racemic modification and so on. Besides, the adsorbent made by gamma-cyclodextrin is used chromatographic analysis. It also can be used as complexing agent and cultivation agent in study of enzymatic activity.
