The advantages and disadvantages of decoration mortar is analyzed

by:Opal     2021-01-18
Compared with other facing materials, decorative mortar has the following features:


the parts of exterior wall thermal insulation system should have physical and chemical stability, all parts should be compatible with each other. Decoration mortar is a kind of inorganic material, is in line with the plaster mortar in composition, so no each other between material corrosion, has a good adhesion between two materials;


decoration mortar has good temperature resistance, will not cracking by temperature changes greatly, which provide good protection for the thermal insulation system;


good decoration mortar crack resistance. To join in the decoration mortar has certain characteristics to disperse latex powder, mortar has certain flexibility, can guarantee won't appear fatigue damage under repeated deformation and fracture;


the main raw material of decoration mortar is


inorganic silicate and quartz sand, paint is also used in the mineral of iron oxide pigments. Inorganic materials is one of the characteristics of good durability, long service life;


porous structure, internal decoration mortar is one of the polymer composition can improve the porosity. This structure can make the water vapor molecules as small molecules through freely, and macromolecule water molecules cannot pass;


decoration mortar is a kind of inorganic material, belongs to the non-combustible material. It can prevent the erosion of polystyrene was open inward to the wall. In terms of fire resistance, decorative mortar has incomparable advantage over other act the role of the surface; Color decoration mortar with ferric oxide and other inorganic pigment dyeing, durable not easy to fade, not as dazzling as the paint color, give a person a kind of simple, stable, has the connotation of feeling; Decoration mortar material is more than 95% of the inorganic material, is tasteless green building materials.


the difference between the decoration mortar and really stone paint: ( In addition to the implementation of the standard is different, and the following difference)


gelled material is different. — — Decoration mortar cementing materials are mainly cement, true stone lacquer is emulsion.


— — Different formulations of decorative mortar with quartz sand and paint toner; True stone lacquer is made of natural colored sand color.


— — System of different color decoration mortar with the color such as ferric oxide series toner color; True stone lacquer is the object of natural body color.


different compactness - — Decoration mortar formula system usually contains a larger mesh powder filling, increased the effect of the surface of the roundness, high compactness; Really stone paint surface of gravel and low compactness.


the difference between the decoration mortar and texture coating: ( In addition to the implementation of the standard is different, and the following difference)


gelled material is different. — — Decoration mortar main gelled material for cement, texture coating for emulsion.


general different combustion performance level - — Decoration mortar can reach A level, texture coating cannot reach A level.


the shortcoming of decoration mortar


decoration mortar weathering easily. — — Weathering is a common problem of cement base material.


and materials, construction, weather and other factors. Manual control is extremely difficult. Decoration mortar basification, at the same time because of basification, easy to produce off color.


the narrow width of color - — Cement itself has color, even if the white cement, color is also far less than demand. Therefore, in the process of color matching, decorative mortar is often not enough bright, not modulation and bright colors.
