1. Before using the product, look for the various types of logos on the outer packaging products and do a good job of sorting (model, color number, working size, etc.) stacking and use.
2. It is necessary to use products with the same color number and working size on the same plane and the same model to ensure the uniformity of the product's effect.
3, paving the wall to be flat, solid, paving before the basic surface of the building should be dealt with (bottom leveling, spray water conservation, impurity removal, etc.), and then follow the paving program hanging line (bomb line) paste, To ensure the formation of a smooth, straight seam. The smooth wall surface is subjected to a flowering treatment to increase the adhesion and adhesion of products and buildings.
4. During the paving process, do a good job of checking and reviewing each process. When a large area is paved, the working surface shall be divided into several small units to organize construction and inspection. 50m2 is generally regarded as a paving and inspection unit.
5, paving to use a reasonable ratio, a homogeneous cement mortar or ceramic adhesive paving, porcelain tiles decorated with dry hanging is better.
6, when paving according to the product surface pattern features (surface pattern characteristics are not obvious by the tile back logo design) uniform direction paving. In general, do not rotate the products to each other by 90°. Products with inconspicuous surface features do not rotate with each other 180°. Generally, they do not affect the effect greatly.
7. According to different product categories and construction requirements, it is advisable to leave 1-5mm uniform gaps between tiles and perform jointing treatment within 24 hours to express different decorative styles and prevent bulging or peeling. Ash joints should be densely packed, flat and slightly lower than the glaze.
8. The use of sealant paving should be strictly according to the requirements of the sealant application material and water ratio, after 6-8 hours of brushing the sealant, it is recommended to carefully clean the brick surface with a clean sponge and water.
9, before the glazed tile shop needs to be fully absorbed. Place the tiles in clean water (not soaked in a box, the surface of the water must exceed the brick surface) and soak for more than two hours. Scoop up and wait for the surface to dry before using. Non-uniformity in water immersion may cause watermarks or chromatic aberrations on the surface of the product to recover over time.
10, tile paving with a reasonable ratio of cement mortar evenly smeared in the paving surface, porcelain tiles recommended by the use of 50% of the 425 # cement in the 14-mesh sieve sand into the cement slurry, glazed interior wall tiles The product should adopt 1:2 cement mortar below 425#, and the mortar thickness should not exceed 6mm. The use of high-grade cement or pure cement paste, as well as excessive thickness of the cement layer, may cause cracks in the glaze.
11, paving tiles should be used to clean the brick hammer with a clean surface (disable hammers and other hard objects beat the brick surface), so that the surface layer and the grass-roots layer bonded dense, solid, no empty drum phenomenon.
The maintenance of the tiles should achieve the ideal construction effect and long-term use effect. The construction and daily use of the products must be operated strictly in accordance with the instructions for use of the products.
1. The ceramic is a brittle material and should be prevented from bumping during construction to avoid damaging the surface.
2. Remove the cement mortar and other foreign materials that adhere to the brick surface during construction, and always keep the brick surface clean.
3. When the product needs to be used for other operations after paving, dry dust shall be used to remove the dust on the surface of the product. Sand, sewage, and other substances that can damage the surface shall not be left. At the same time, a protective layer shall be applied on the surface.
4. It is forbidden to polish the surface of the product and to clean it with hydrofluoric acid and hydrofluoric acid-containing liquids.
5, the daily use of stains infiltration should be promptly removed, such as stubborn stains need to use a professional cleaning agent to prevent the destruction of the tile surface by a hard object, there is no protection layer not to perform other operations on the brick surface.

Thrust Spherical Roller Bearing
A spherical roller thrust bearing is a rolling-element bearing of thrust type that permits rotation with low friction, and permits angular misalignment. The bearing is designed to take radial loads, and heavy axial loads in one direction.
Spherical roller thrust bearings are of separable construction, The shaft washer is assembled with the cage and a number of asymmetrical spherical rollers and has to be used along with a housing washer having sphered raceway. During mounting, the rings are to be fixed on to their respective seats – shaft washer on the shaft and housing washer on to the housing and then they have to be put together carefully They are manufactured in multiple series.
The raceway of the housing washer is at an angle with it`s ais of rotation, so as to be able to allow the rollers to remain in touch with it. As a result, a spherical roller thrust bearing is capable of carrying both a radial as well as an axial load. Spherical roller thrust bearings – because of their internal geometry – are capable of accommodating certain amount of misalignment. However, they can take axial loads only from one direction, and may need to be used in pairs in Back-to-Back or Face-to-Face arrangement, if thrust load from both the directions are to be carried.
Spherical roller thrust bearings are capable of compensating misalignment and shaft deflection.
The bearings are manufactured in normal accuracy. However, bearings with higher running accuracy can also be supplied.
