A good news came from Hohhot, Inner Mongolia, China Zhonghai Chemical Tianye Company successfully produced pellet products with an annual output of 60,000 tons of polyformaldehyde C-line. At this point, the largest single polyoxymethylene project in China was successfully completed and put into full operation in China National Oceanic Corporation. The China Chemical Industry Chain has been successfully extended and expanded.

The polyoxymethylene project of China Ocean Chemical Tianye Co., Ltd. has a total of three production lines, which can produce about 60,000 tons of polyoxymethylene annually. Polyoxymethylene has a long process flow, especially for process conditions. According to the design and domestic and foreign precedents, the polyoxymethylene plant generally takes 3 months to drive, and the temperature cannot reach below 10°C. In the cold environment of minus twenty degrees Celsius in winter, the tester of China National Ocean Chemical Tianye Company achieved production of qualified pellets on November 19 last year in only 25 days, and set a precedent for domestic and foreign customers. With the experience of successful test of the A-line, they opened the POM B line feeding test curtain on December 30, 2010. On January 11, 2011, it took only 13 days for line B to successfully produce polyformaldehyde pellets. On May 19th, 2011, the polyoxymethylene line C was fed through a dozen units such as formaldehyde concentration, tripolyformaldehyde monomer production, polymerization, grinding passivation, monomer removal, blending, and granulation packaging. On June 7, qualified pellet products were produced. Up to now, a full set of equipment has produced more than 10,000 tons of polyformaldehyde, which has injected vitality into the domestic polyformaldehyde market.

It is understood that the company's annual production of 60,000 tons POM project has been listed as a special research topic in the field of major new materials by Hohhot Chemical Amano. It has received strong support from policies and funds, and also established a special laboratory to improve the quality of POM. Sexual research.

It is also known that polyoxymethylene is a high-tech thermoplastic engineering plastic that is widely used in fields such as electrical and electronic equipment, machinery, instruments, daily-use light industry, automobiles, building materials, and agriculture. "Steel" is the future metal replacement material. Currently, there are not many enterprises that can master polyformaldehyde production technology and can produce qualified polyformaldehyde. There are few product varieties, and most of them rely on imports. Currently, the import volume accounts for about 50% of domestic consumption.

Featurers of Model CL-80/100/80H-1500mm

1.Strong Double Layer Vacuum Box Device

Strong Double Layer Vacuum Box Device helps absorb the hot air between film and cooling roller,which makes the film be more closed and tightly to the cooling roller thus enhance the cooling effect when the machine is running in high speed.

2. High Quality and Updated Advanced Cooling System

The cooling roller's diameter is 1000mm with bi-directional loop design and helix runner inside.The high-precision steel is adopted to ensure stable temperature on roller surface.

3.Melting Pump--Plastic melt metering pump is more and more important in extrusion process, especially in high-end products industries, such as high quality sheets, pipes, BOPP, optical cable.Installing the melt metering pump in the cast stretch film unit can make the machine produce constantly and efficiency. The pump can improve the product quality, stable the production process and decrease the energy consumption.

4.Four Air Shaft Roll Changers Device

One roll change takes only 30 seconds and this system can help produce small hand roll online when the machine is running in high speed.And so there is no need to install a Rewinding Machine to rewind,which helps save a lot of time, cost and labor.

Plastic melt metering pump is more and more important in extrusion process, especially in high-end products industries, such as high quality sheets, pipes, BOPP, optical cable.

Installing the melt metering pump in the cast stretch film unit, which can keep the production constantly and efficiency. The pump can improve the product quality, stable the production and decrease the energy consume.

The housing is made of chromium-nickel alloy or nickel-base alloy, titanium alloy. The gear is made of quenching chromium steel, other metal materials are also applicable. Bearing is made of graphite NIAG, zirconium oxide or quench tool steel.

Advantages:

FAST AND STABLE FLOW SUPPLY

Eliminated the extruder`s pulsation wave. Improve the product quality, decrease the defective rate, and decrease the waste, which can save 2% material and 25% of the unit power consumption.

STABLE AND EFFICIENCY PRESSURE CONTROL

The melt pump can provide a stable pressure, which short the discharge time obviously and make the production effectively.

INCREASE THE EXTRUDER OUTPUT AND THE MACHINE LIFE

It has been found that after install the melt pump, the max pressure wave value is the pressure after pump. Which can make the inner pressure of the extruder decrease, the melt shear strength decrease, the temperature curve gently, and restrain the temperature rising. Also the melt pump can avoid the damage to the extruder from the high pressure.

Main Technical Specification of CL-80/100/80H-1500mm

(Such as plastic film machinery.)

(1) Overall Dimensions(L*W*H): 14m*6.5*4.45

Max width of rewinding: 500mm*3

Max Rewind Diameter: ø400mm

Liner speed of machinery: 350m/min

(2)Rewind the film by combining it`s surface and core to make the film roller tightly closed and level and smooth.

(3)Remove the film roller and install the paper tube at the same time, which only takes about 25-30s and produce 2-3kg small film roller when the machine is running in high speed.

(4)Automatic edge material recycling system with on-line vacuum makes the process of rewinding more smooth, increases the fracture resistance, and decreases the limitation by liner speed.

(5)The recycling materials are extruded out from only and specific screw to stable the the extrusion system and to decrease the deviation about the weight of film.

(6) The extrusion machine is driven by coupling which stables the extrusion process and therefore stables the film output from die head.

(7)Prompt measurement to adjust the thickness and uniformity of the film easily.
