Needle roller punching machine series
The punching machine is a kind of mechanical equipment that is driven by the power mechanism after the raw material is installed, and the punching die acts on the material to complete the punching. The punching machine can perform operations such as sheet processing, stamping, molding, embossing, etc. that force metal into the mold.
The series of desiccant deoxidizer film perforating needle rollers developed by our company adopts imported alloy steel wire needles with high strength and good abrasion resistance, and advanced perforation technology. The processing accuracy reaches the same level in the world. The air permeability detection is uniform and stable.

The stable operation of the on-line chromatographic analyzer can provide important control data for optimizing ethylene production and increasing the ethylene yield. It is one of the key process parameters of the ethylene plant. According to reports, this technology is aimed at the unstable operation of the cracked gas on-line chromatograph analyzer in petrochemical plants and the problem of inaccurate sampling data. Based on the original sampler, it firstly created the secondary cyclone separation technology, which enabled the analysis of sample gas after two cyclone separations. Achieve a good oil and gas separation effect to ensure the long-term stable operation of the analyzer.
The use of new technologies makes the analytical measurement results of the online chromatograph more accurate and stable. At the same time, the maintenance workload of the entire analysis system is greatly reduced, which effectively reduces the operational risk of the ethylene combined device. The key technology in this achievement, the vortex refrigerant oil mist separation method, has applied for a national invention patent.
At present, the on-line chromatograph analyzers of 10 ethylene cracking furnaces that have been included in the research plan are stable and the data analysis is accurate. The requirements for crack depth control are met, and the success rate of research is 100%.
The on-line analysis of ethylene cracked gas is performed on-line analysis of pyrolysis gas produced from naphtha, light naphtha, atmospheric diesel, decompressed diesel, hydrogenated tail gas, ethane, liquefied petroleum gas, etc. as raw materials. The yield of pyrolysis feedstocks converted to pyrolysis products, ethylene, propylene, and butadiene, was measured as the effect of the cracking process.
This series of needle rollers are widely used for perforating various kinds of desiccant deoxidizer films for food, various kinds of micro-perforated or air-impermeable plastic packaging films, and medicinal packaging films. There are cold perforated needle rollers for direct perforation and heated perforated needle rollers.
Our company specializes in the supply of desiccant perforated needle rollers, deoxidizer film perforated needle rollers, wholesale of film perforated needle rollers, product quality and processing technology reliability, and stability are at the domestic advanced level, and can be produced according to customer requirements. Special specifications of needle roller, needle ring products. Welcome customers to consult.
