The cracks, peeling, and shedding of the automatic putty scraper are mainly caused by the poor adhesion of the putty and the base. If the base layer is not cleaned properly or the treatment method is improper, the template release agent, oil, inorganic acid and organic acid on the base layer are not completely removed, there is no aqueous solution of fire alkali (for removing oil stains on the wall), and there is no adhesive or putty. Improper blending of the formula emulsion will reduce the bonding strength between the putty and the base layer.
The putty coating is too thick. The thickness of the putty coating is related to the choice of materials and mix ratio. Such as scraping big white putty, in order to facilitate operation. The amount of talcum powder is more, improving the lubricating performance of putty. Generally, the coating will not be too thick; but if the filling effect of putty is used, the amount of big white powder will increase. The self-powder particles are coarse, the putty has poor lubrication performance, and it is not easy to operate. At this time, the coating may be too thick.
The fully-automatic putty scraping machine can play a very good effect. Let's take a specific look at where it is suitable for use. The necessary conditions are necessary, that is, the construction site must be equipped with hydropower. This is the basic condition, otherwise it will not work. For the flat ground, the construction site should try to choose the safe flat ground. If the ground is not flat, it will affect the flatness of the putty.
No children are allowed, and children must be isolated on the machine construction site, otherwise more dangerous things will happen easily. The prepared mortar is just a simple application, and can not distinguish the quality of the putty, so it is necessary to prepare the putty mortar.
