Heat extrusion system of micro passage aluminum flat pipe, online zinc spray system are delivered for use
The microchannel zinc-aluminum flat tube chamber adopts a refined aluminum rod, a microchannel aluminum tube (also referred to as a "parallel flow aluminum flat tube") which is treated by hot extrusion and surface zinc spray anticorrosion treatment, and is a thin-walled porous flat tubular material. It is the key material for the new generation of parallel flow microchannel air conditioning heat exchangers. This product is mainly used in various air-conditioning systems using new environmentally friendly refrigerants. As a pipeline component carrying new environmentally friendly refrigerants, it uses parallel flow microchannel heat exchangers, which are similar to traditional copper tube-through tubes and aluminum. Compared with the tube-snake-type coil exchanger, the micro-channel zinc-aluminum flat tube has outstanding environmental protection, efficiency, energy saving and cost reduction.
The zinc coating on the surface of the zinc-coated aluminum tube is required to be high: the atomized particles are micron-submicron, and the amount of zinc per unit area is strict. International high-end products: Micro-channel zinc-aluminum tubes used in automotive, commercial and domestic air-conditioning heat exchangers are basically produced by hot extrusion. And the production method generally used is a large-tonnage press (generally 2200T--3600T) with a bar (100Kg or more) as a raw material for stripping and extruding a plurality of microchannel aluminum tubes.
Since entering the industry in 2005, Shanghai Liangshi Spraying Equipment Co., Ltd. has continuously satisfied the needs of its customers by relying on its own R&D and production advantages. At the same time of increasing its reputation, our technology research and development and manufacturing advantages are simultaneously in the presence of multiple microchannel aluminum flat tubes. Online application of zinc and dust removal has been applied and shined.
In the field of continuous extrusion (Kangfeng machine production microchannel aluminum flat tube) and hot extrusion (small tonnage horizontal extruder one out of 1 mode production microchannel aluminum flat tube) field first fully realized unmanned operation: one button start , automatic shutdown alarm, three-level dust removal, strict implementation of national environmental standards for gas emissions. Fully realized unmanned operation: one-button start, automatic shutdown alarm, three-level dust removal, strict implementation of national environmental standards for gas emissions.
Although a small number of domestic manufacturers continue to research and develop and overcome the technology of producing multiple microchannel aluminum tubes at the same time, in the subsequent online zinc spraying and dust removal equipment, all domestic thermal spraying equipment suppliers are unable to provide coatings that can be close to imported equipment. The surface quality system, each manufacturer can still rely on imported zinc spray equipment to complete the zinc spray process on the surface of aluminum tubes. Multiple spray guns are arranged in the narrow aluminum tube space. At the same time, if a large tonnage press (generally 2200T or more) produces four microchannel aluminum tubes (commonly known as one out of 4), eight sets of zinc spraying systems must be used. A set of supporting dust removal system, this zinc spray system is monopolized by British and Japanese companies!

The user test data shows that the salt spray test of the zinc spray layer meets the relevant standards, the zinc content and uniformity of the coating unit area meet the highest requirements of the industry, and the roughness meets the requirements of the user standard. It can be seen that the surface quality of the aluminum tube obtained by the latest equipment of our company is excellent, and the coating is beautiful, which has been affirmed by users.
The friendly cooperation with the largest domestic manufacturer of micro-channel aluminum flat tubes using horizontal extruders has made our company the only and largest manufacturer and supplier of micro-channel aluminum flat tube zinc-spraying system equipment in China. Status makes us feel that we have a great responsibility to support the growth of national enterprises!
During the process of arc-spraying zinc, due to the relationship between the width of the aluminum tube and the principle of spraying itself, about 70% of the zinc material transported will be atomized and fleeing. If not collected, the environment and operation will be carried out. The personnel bring damage; at the same time, the process of spraying zinc will produce a large amount of toxic waste gas. If it is not collected, it will also cause harm to the operator and cause serious pollution to the workshop. We make full use of the latest theories and achievements of modern dust removal, use a reasonable combination of dust removal methods to achieve the purpose of environmental protection and labor protection, so that the production environment and the external environment meet the relevant standards of labor hygiene and industrial emissions.

The zinc-spraying system equipment on the surface of aluminum tubes involves a comprehensive display of multi-disciplinary and multi-disciplinary industrial technologies. It requires not only the research and development of the fields, but also the experience and capabilities of the production. It also requires the ability to integrate and integrate the technologies of various disciplines. Top technical talent team
Good system service has become a major factor in the success of Shanghai Liangshi in this industry. So far, we have successfully provided four production lines for Jiangsu customers.
