It has excellent mechanical properties and can be machined for cutting, welding, etc. It has high compressive strength, and the internal pressure breaking strength is as high as 0.3mpa or more; its filtration accuracy is easy to guarantee, and even if it works under high temperature and high pressure, the pore diameter will not be deformed. Its porosity can reach 35-45%, the pore size distribution is uniform, the dirt holding capacity is large, and the regeneration method is simple, and it can be reused after regeneration.

Production Process:

The metal microporous titanium powder sintered corrugated plate is made by adding high-purity powder into the rolling mill and rolling under pressure, as shown in the rolling mill as shown below:

After being rolled and formed by a rolling mill, high-temperature sintering is carried out in a vacuum sintering furnace, as shown in the following vacuum sintering furnace:

Note: 1. During the rolling process, the pressure of the rolling mill is very important, which affects the air permeability of the board. Yinggao has professionals to carry out pressure rolling to ensure the air permeability is qualified.

2. The sintering time in the vacuum sintering process affects the service life of the board, so sufficient and appropriate sintering time is the key process of the sintering process.

8. Precautions for use:

1. Titanium filter elements are consumables. Although they are more durable than other filter elements, care should be taken not to scratch, bump, smash, or drop during cleaning and disassembly to prevent human-made damage. It is strictly forbidden to use tools to exert force on the surface of the filter element. 2. Under normal circumstances, the filtrate is filtered from the outside of the filter element to the inside, and reverse filtration is not recommended. the

3. When filtering, pressurize slowly to the required working pressure, and it is strictly forbidden to open the valve to pressurize quickly. the

4. Maximum working pressure ≤ 2MPa. When the filtration efficiency is lower than 50%, it is necessary to use clean air or clean liquid to backwash and backwash online in time. the

5. When backflushing and backflushing the titanium filter element, generally use pure gas to backflush first. The backflush pressure is 1.2-1.5 times the working pressure. Backwash with clean solution, backwash for 3-5 minutes, 2-3 times. the

6. If the pressure loss of the filter element is still serious after online backflushing and backwashing, it should be removed in time

Nine, cleaning method:

According to the pollution situation and the chemical properties of the pollutants and the physical and chemical properties of titanium metal, the titanium filter element can be regenerated and cleaned by physical and chemical methods. Physical methods mainly adopt: clean liquid backflushing, clean gas backflushing and ultrasonic cleaning. Chemical methods mainly use: dilute acids, dilute alkalis, oxidants, surfactants, enzymes and other cleaning agents. The above methods can also be used interchangeably. the

According to several common application situations, the cleaning method is as follows:

1. For decarbonization and filtration in the pharmaceutical and chemical fields, backflushing and backwashing methods are often used in combination with ultrasonic cleaning to achieve good results. the

2. In the water industry, since most of the intercepted water-insoluble salts and oxides on the surface of the filter element are soaked in 5% nitric acid, the cleaning effect can be achieved without ultrasonic cleaning. the

3. For raw liquid filtration, the following methods should be used for cleaning in combination with the chemical properties of pollutants:

(1) Alkaline cleaning: Soak in 3-5% sodium hydroxide analytically pure solution for 30-60 minutes at a temperature of about 40 degrees, which is best in an ultrasonic cleaner. After immersion, flush the inside and outside with filtered deionized water or water for injection until neutral, and measure the conductivity. Blow dry with pure air ≥ 0.4MPa pressure. the

(2) Pickling: Soak in 5% nitric acid solution for more than 8 hours at a temperature of about 40 degrees. Best in ultrasonic cleaners. After soaking, rinse the inside and outside with filtered deionized water or water for injection to neutrality and side conductivity. Blow dry with pure air ≥ 0.4MPa pressure. the

(3) Organic matter pollution can be cleaned in combination with surfactants, and the cell debris pollution system combined with enzyme cleaning is more effective (food and beverages can be cleaned with high-concentration citric acid). the

(4) The above methods can be used alone or in conjunction with each other. If conditions permit, the effect of combining with an ultrasonic cleaning machine is good. Note: Frequent online backflushing (online cleaning with pure compressed air or filtered stock solution or clean water backflush), can reduce the number of times of cleaning with the above methods.
