Since the 1990s, China's packaging and printing machinery industry has made rapid development, in terms of variety, quantity, technology, quality, etc. have been greatly improved. In the manufacturing technology not only improve the accuracy, but also pay attention to the application of mechatronics and computer control, and strengthen the basic support in the special valve, electronic components and electrical control components, pneumatic diaphragm pump is ink circulation device Essential accessories. The United States, Japan, Germany, Italy's printing machinery are equipped with this pneumatic ink pumping device. Our cartons and plastic printing machines have been equipped with pneumatic diaphragm pumps since the mid-nineties to replace electric pumps that are prone to sparks and are prone to bubbles of ink during work. The "Changjiang" brand pneumatic diaphragm pump has the characteristics of safety, energy saving, high efficiency and durability. Due to the use of compressed air as the driving force, it will not cause sparks, static electricity or electromagnetic interference in the working process and is suitable for flammable and explosive occasions. Media flow according to the needs of the printing press, through the pump needle valve stepless adjustment. After the pump starts to work, the ink continuously reciprocates to prevent the ink in the ink tank from crusting, so as to improve the printing quality. The pump body and filter are made of alloy casting. All parts in the pump are made of high quality corrosion-resistant materials. The special diaphragm and corrosion-resistant ink tube are resistant to ester, ketone, benzene, alcohol and other solvents. The working principle of "Changjiang" brand pneumatic diaphragm pump: under the action of compressed air, the reciprocating motion of the air-chamber auxiliary mechanism in the pump drives the diaphragm to actuate the medium (such as ink, glue, solvent, etc.) in the pump chamber Compression and extraction, play the purpose of transporting media. "Changjiang" brand pneumatic diaphragm pump type: (1) CJ601-type pneumatic one-way diaphragm pump: ordinary type. (2) CJ601S type pneumatic one-way diaphragm pump: with manual ink return device, more convenient for color change or cleaning. (3) CJ602-type pneumatic two-way diaphragm pump: two-way fluid supply, flow rate is one-way diaphragm pump 2 times more stable performance, more suitable for high-speed high-end plastic printing machinery.
Waterproof Sealant
One-component Exposed Polyurethane Sealant is a solvent-free one-component sealant.The sealant is in paste form and can be squeezed out or applied by spread.Sealant is a material used to fill voids (holes, joints, seams, etc.) and has both the functions of bonding and sealing.Adhesive to metal, rubber, wood, cement components, ceramics, glass, etc.The cured rubber layer is rubbery and elastic.
Wide adjustable range of performance.Adhesive to metal, rubber, wood, cement components, ceramics, glass, etc.Excellent adhesion to almost any type of surface with or without special primers
Excellent extrusion, processing and storage stability in a wide range of climatic conditions. Put the sealant into the glue gun and use it immediately.
The sealant can remain elastic at temperatures of -40°C and can also be used for high-temperature roofing applications above 60°C.
The sealant is suitable for the sealing of swimming pools and chemically distilled water.
Sealants can be exposed to the outdoors for a long time and resist biological aging.
