The quality of the paste of the wall tiles directly affects the decoration effect, especially the paste quality of the deep color sleeve bricks. The evaluation of the quality of home decoration is more prominent and must be constructed strictly according to the standard procedures to ensure the quality.
Wall tile paste is one of the main technical tasks of bricklayers in home renovation projects. The paste program for the specification of the wall tiles is: grassroots sweeping treatment → wiping the base ash → selecting bricks → soaking → rowing bricks → playing a line → pasting a standard point → pasting a tile → sewing → wiping a seam → cleaning.
First, the wall tile paste construction specifications
1. When processing at the grassroots level, all types of dirt on the wall should be cleaned and watered and moistened one day in advance. For example, when the grass-roots level is a new wall, when the cement mortar is 70% dry, bricks, bullets, and tiles must be placed.
2, before the official paste must be pasted standard points, to control the smoothness of the paste surface, the operation should be used at any time to check the flatness by the ruler, uneven, not straight, to remove the re-adhesive.
3, tile paste must be soaked in clean water for more than two hours before the brick body does not bubble prevail, remove the dry stand-by. Paste from the bottom up paste, requiring mortar full, ash, must remove the heavy sticky, not allowed from the brick joints, mouth ash filling pad.
4, when sticking to meet the pipeline, lighting switch, bathroom equipment support, etc., must use a whole brick set of cut and match, prohibit the use of non-whole brick patchwork paste. The whole or independent part of the paste should be completed at one time, and once it cannot be completed, the joint mouth should be left at the construction joint or the female corner.
Second, the wall tile paste inspection and acceptance of the wall tiles must be solid, no skew, missing edges and cracks and other defects.
Wall tile paving surface should be flat, clean, color coordination, reasonable pattern arrangement, no discoloration, pan-alkali, stains and significant gloss damage. The brick joints are densely packed, straight, uniform in width and width, and uniform in color. The lap direction at the yin and yang corners is correct. Non-whole bricks are suitable for use and are arranged straight. The hole has the correct size and the edges are neat. Inspection flatness error is less than 2 mm, facade vertical error is less than 2 mm, seam height deviation is less than 0.5 mm, and flatness is less than 2 mm.
Third, the wall tile paste common quality problems and treatment methods
The common quality defects of wall tile paste are empty drum fall off, discoloration, uneven seams and surface cracks.
1, empty drum off: The main reason is that the adhesive material is not full, the bricks are not soaked enough and the base layer is not processed. During construction, the bricks on the sleeve must be clean and free from immersion for not less than 2 hours. The thickness of the adhesive should be controlled between 7 and 10 mm and should not be too thick or too thin. When sticking, it is necessary to make the tile and the bottom layer stick densely. You can tap it with a wooden hammer. When hollow drums are produced, the wall tiles shall be removed, the original bonded mortar shall be removed, and cement mortar shall be used to repair the total volume of 37 glue.
2, color change: the main reason in addition to poor tile quality, axial surface is too thin, the operation method is also an important factor. The materials should be strictly selected during construction, and clean water should be used for soaking the sleeve bricks. Paste cement mortar should use pure sand and cement. Always clean the remaining mortar on the brick surface during operation. If the color change larger wall tiles should be updated.
3, seams are not straight: The main reason is that there are differences in the specifications of bricks and improper construction. The bricks should be carefully selected during construction and the same kind of dimensions should be used together for one wall. The standard points must be posted. The standard points must be on the basis of the ruler. After each line is pasted, it should be checked in a timely manner by using the ruler horizontally and vertically. If the joints exceed the allowable error, the wall tiles should be removed in time for rework.
Fourth, the wall tile paste the estimated time
Wall tile paste is a highly technical construction project. It takes a lot of man-hours, and when the auxiliary materials are prepared and the grassroots processing is better, each worker can complete about 5 square meters a day. The general family decoration is glued to the bathroom and the kitchen wall. Face takes about 7 days. Different specifications of ceramic wall tiles, different binders used, and different number of basic wall pipes will affect the construction period. Therefore, the actual construction period should be determined according to site conditions. Paste the wall tile construction, can be parallel or cross-operation with other projects, but should pay attention to product protection.

One of the most fascinating materials of our time is polycrystalline cubic boron nitride PCBN - the second hardest material after diamond. At CeramTec, PCBN is used as a cutting material from which indexable inserts are manufactured for machining.
PCBN is produced synthetically and is a "composite material" made of cubic boron nitride and a mostly ceramic binder phase. The ratio of cBN to binder content and the cBN grain size determine the application.
PCBN cutting materials are used in the machining of hard and/or highly abrasive workpiece materials. The high hardness and the extremely high hot hardness (up to temperatures above 1,000°C), the edge stability and inertness towards ferrous materials as well as the basically good chemical resistance give CBN cutting materials a high potential for use in machining. On the cutting material side, a distinction is made between high- and low-cBN cutting material grades.
PCBN (Polycrystalline Cubic Boron Nitride) blanks for cutting tools are composite ultrahard materials sintered by polycrystalline CBN and carbide alloy under ultra-high pressure and high temperature conditions. They combine the hardness, wear resistance, and thermal stability of CBN with the impact resistance and toughness of carbide alloy. PCBN blanks are highly suitable for cutting ferrous and non-ferrous metals with high hardness.
