In the renovation, the installation of the toilet is very critical, and the acceptance is also very particular. It is not only necessary to look at the final result. During the installation process, workers must be allowed to perform the construction according to the specifications, so as to avoid hidden dangers in the future life. What are the installation specifications?
(1) Take out the pipe plug of the ground water outlet, and check that there is no debris in the pipe. Clean the area around the nozzle.
(2) Align the outlet pipe of the toilet with the outlet pipe, place it flat, and draw a mark on the hole of the toilet bolt and remove the toilet.
(3) Insert a hole with a diameter of 20 mm and a depth of 60 mm at the imprint, insert a 10 mm diameter bolt into the hole, secure it with cement, align the eye of the toilet with the bolt, align it with the mark, and after the test, The toilet was removed. Put putty around the outlet of the toilet bowl and the nozzle of the water pipe, and then align the four bolt holes of the toilet with the bolt, lay it flat and align it. Put a rubber pad on the bolt and screw it on until the nut is tight.
(4) Align the back center of the toilet and draw a vertical line. Draw a horizontal line at a height of 800 mm from the ground. Draw a seal on the horizontal line according to the positions of the two side holes on the back of the tank. Play a diameter of 30 mm at the hole. 70 mm hole. Insert a bolt 10 mm in diameter and 100 mm in length into the hole and secure it with cement. Hang the back water tank on the bolt and align it with the center of the toilet. Specially align with the center of the toilet bowl. Place a good rubber pad on the bolt, screw on the nut, and tighten it until it is tight.

Sanding Belt
Abrasive belt is a belt-shaped tool that can be ground and polished, which is made by bonding abrasives to flexible materials such as paper and cloth with a binder. It is a main form of coated abrasives. Its basic composition is: base material, abrasive and binder, collectively called the three elements of abrasive belt. Abrasive belt is the main tool of the sanding process. Abrasive belt grinding is a soft grinding method, which is a compound processing abrasive tool with multiple functions of grinding, grinding and polishing.
Abrasive tools are tools for grinding, grinding and polishing. Most of the abrasives are artificial abrasives made of abrasives and bonding agents, and natural abrasives are also directly processed from natural ore. In addition to being widely used in machinery manufacturing and other metal processing industries, abrasive tools are also used in the processing of non-metallic materials such as food processing, paper industry and ceramics, glass, stone, plastic, rubber, and wood.
Abrasives are divided into natural abrasives and artificial abrasives. All materials that can be used for grinding or grinding in nature are collectively referred to as natural abrasives.
Natural abrasives mainly include: natural corundum and garnet
Artificial abrasives mainly include: white corundum, brown corundum, silicon carbide, zirconium corundum, synthetic diamond, cubic boron nitride.
How to choose a suitable abrasive belt and further improve the smoothness and flatness of sanding is a very important issue in the use of abrasive belts. Due to the differences in the three major components of abrasive belts and various characteristic factors, abrasive belts can be divided into many varieties according to different grinding objects, grinding conditions and grinding requirements. The following is the classification of abrasive belts according to abrasives. Different abrasive belts are suitable for different products. The following types of belt operations are: automatic grinding, mechanical hand grinding, desktop grinding, and manual tool grinding.
Types of abrasive belts (according to abrasives):
1: Accumulated abrasive belt
Application: Widely used in polishing various non-alloy, low-alloy and high-alloy steel, stainless steel, brass, bronze and other non-ferrous metals. Good self-sharpening, long service life, uniform grinding volume and uniform surface roughness.
2. Brown corundum belt
Application: Widely used in metallurgy, machinery, shipbuilding, wood, building materials, textile printing and dyeing industries. Grinding and polishing of bamboo and wood products, decorative panels, stainless steel, non-ferrous metals and other complex surfaces. Fast cutting, heat resistance, long service life, efficient wear resistance.
3. Ceramic abrasive belt
Application: Widely used in grinding chromium steel, chromium-nickel steel, stainless steel, high-alloy steel, nickel-based alloy, titanium alloy, brass and bronze, etc., with good self-sharpening, strong grinding, and large removal of grinding materials.
4. Silicon carbide belt
Application: Widely used in the grinding and polishing of brass, bronze, titanium alloy, aluminum alloy, glass, ceramics, minerals, stone, rubber, and synthetic materials. The sand surface is sharp, with very high strength and grinding ability, suitable for grinding medium and high density plates. The bucky has strong tension and ultra-wide sub-tension, which can be used for ultra-large abrasive belts.
5. Zirconium corundum abrasive belt
Application: Widely used in the grinding and polishing of steel, alloy steel, cast iron and non-ferrous metals, medium load or heavy load powerful grinding. The rigid polyester fabric is resistant to strong tension and impact, has high abrasion resistance, and has excellent comprehensive cost performance.
