When using the visual method to identify the quality of the gypsum board, the front side of the board should be visually inspected under the condition of bright light of 0.5m, first look at the surface, the surface is smooth and smooth, and there should be no pores, stains, cracks, Insufficient angle, uneven color and incomplete pattern, the upper two layers of paper on the plasterboard should be strong, which can prevent cracking and crack the gypsum board when the screw is screwed; look at the side to see if the plaster texture is dense. There is no empty drum phenomenon, the more dense the gypsum board is more durable.
2, tapping by hand
This is mainly used to check the elasticity of the plasterboard. It is tapped by hand and gives a very solid sound. The gypsum board is durable and durable. If the sound is very empty, the board has an empty drum and the texture is not good.
3, size tolerance, flatness and right angle deviation
Dimensional tolerance, flatness and right-angle deviation should meet the eligibility criteria. If the deviation of the decorative gypsum board is too large, the decorative surface will be irregularly tidy, and the entire surface will be uneven, which will have a great influence on the decorative effect.
4, look at the signs
On each package, there should be the name of the product, the trademark, the quality grade, the name of the manufacturer, the date of manufacture, and the signs of moisture, care and product marking. If the signs on the package are not uniform, or none at all, it means This kind of product is not produced by a formal company. It is recommended not to buy it.
What are the buying tips for buying plasterboard:
1. Ask for a quality inspection report to understand the quality of the product.
2, check the appearance quality, carefully check whether the front of the gypsum board has oil stains or watermarks, whether the front of the gypsum board is flat, there are more and deeper corrugated grooves and scratches.
3. Check the degree of bonding between the facing paper and the core. It is necessary to randomly find a few sheets, and use the gypsum core and the face paper to expose the facial tissue at the end. If the exposed facial tissue paper is peeled off between the layers, it indicates that the protective paper of the sheet is bonded with the gypsum core. Good; if there is a tear between the exposed facial paper and the plaster core layer, it indicates that the sheet is poorly bonded.
