Waste press dewatering technology

Unclear garbage trucks are special vehicles for transporting urban rubbish. However, in recent years, the garbage truck transportation industry also has many problems that need to be rectified. For example, it goes all the way in the process of transporting rubbish and drops garbage water, which pollutes road surfaces and emits odors. While increasing the workload of the cleaners along the road, it also made many people resentful. Due to the high water content of domestic garbage trucks in China, many problems have arisen for the transfer of garbage and the handling of terminals. The waste disposal costs and disposal costs are greatly increased, which is not conducive to the direct incineration and recycling of energy. In order to solve the problems of high moisture content in garbage and difficulty in garbage classification, the government has vigorously carried out research on rapid waste dewatering technology applicable to garbage transfer stations, increased the efficiency of compression and transport of existing garbage transfer stations, reduced secondary environmental pollution, and effectively reduced waste. Moisture content, at the same time do waste dry and wet classification, eliminate environmental pollution caused by the secondary operation process of garbage, and increase the heat value of waste combustion. This technology not only saves manpower but also improves work efficiency.

After a car's garbage has been transported, the staff only needs to remove the trash can and pull it to the place where the trash can is placed on the front of the pre-compression type mobile garbage compression box. When the button is pressed, the loading machine of the pre-compression type mobile garbage compression box is automatically turned over. Trash, enter the box. Closed trash cans are self-compressed and the entire process is handled by dedicated personnel. It is worth noting that during the processing of domestic waste, there will be a “water mist” jet that will not produce odors during the entire dumping process. Because "this kind of spray equipment is our high-pressure spray deodorization system installed in the garbage station, the sprayed mist is a special natural plant deodorant, non-toxic and harmless to the human body. It can not only remove dust, deodorize, but also achieve disinfection. The effect of this technology is that it has limited the problem of garbage and water, improved work efficiency, reduced manpower output, and really played the role of environmental protection.

Titanium Dioxide(TIO2)

Titanium dioxide is an important inorganic chemical pigment, the main component is titanium dioxide. The production process of titanium dioxide has two process routes: sulfuric acid method and chloride method. It has important applications in coatings, inks, papermaking, plastics and rubber, chemical fiber, ceramics and other industries.

It has two types: rutile type (Rutile R type) and anatase type (Anatase A type). The rutile crystal structure is compact, relatively stable, and has low optical activity, so it has good weather resistance, and has high hiding power and decolorizing power.

Titanium dioxide is widely used in coatings, plastics, rubber, ink, paper, chemical fiber, ceramics, daily chemicals, medicine, food and other industries.
The coating industry is the largest user of titanium dioxide, especially Rutile Titanium Dioxide, most of which is consumed by the coating industry. The paint made of titanium dioxide has bright colors, high hiding power, strong tinting power, low dosage, and many varieties. It can protect the stability of the medium, and can enhance the mechanical strength and adhesion of the paint film to prevent cracks. Prevent the penetration of ultraviolet rays and moisture, and extend the life of the paint film.
The plastics industry is the second largest user. Adding titanium dioxide to plastics can improve the heat resistance, light resistance, and weather resistance of plastic products, improve the physical and chemical properties of plastic products, enhance the mechanical strength of the products, and extend the service life.
The paper industry is the third largest user of titanium dioxide. As a paper filler, it is mainly used in high-grade paper and thin paper. Adding titanium dioxide to the paper can make the paper have better whiteness, good gloss, high strength, thin and smooth, no penetration during printing, and light weight. Titanium dioxide for papermaking generally uses Anatase Titanium Dioxide without surface treatment, which can act as a fluorescent whitening agent and increase the whiteness of paper. However, laminated paper requires the use of surface-treated rutile titanium dioxide to meet the requirements of light resistance and heat resistance.
Titanium dioxide is also an indispensable white pigment in advanced inks. The ink containing titanium dioxide is durable and does not change color, has good surface wettability and is easy to disperse. The titanium dioxide used in the ink industry has rutile type and anatase type.
The textile and chemical fiber industry is another important application field of titanium dioxide. Titanium dioxide for chemical fiber is mainly used as a matting agent. Since the anatase type is softer than the gold red type, the anatase type is generally used. Titanium dioxide for chemical fiber generally does not require surface treatment, but in order to reduce the photochemical effect of titanium dioxide and prevent the fiber from degrading under the action of titanium dioxide photocatalysis, surface treatment is required for some special varieties.
The enamel industry is an important application field of titanium dioxide. The enamel grade titanium dioxide has high purity, good whiteness, fresh color, uniform particle size, strong refractive index and high color reducing power, and has strong turbidity and Opacity, make the coating thin, smooth and strong acid resistance after enamelling. It can be evenly mixed with other materials in the enamel manufacturing process, does not agglomerate, and is easy to melt.
The ceramic industry is also an important application field of titanium dioxide. Ceramic grade titanium dioxide has high purity, uniform particle size, high refractive index, excellent high temperature resistance, and does not change ash at 1200°C for 1 hour. High opacity, thin coating, light weight, widely used in ceramics, construction, decoration and other materials.
