Polyurethane spraying equipment has been widely used in the exterior wall thermal insulation spraying industry. In order to better complete the spraying work, the cleaning of spraying equipment such as polyurethane high-pressure spraying machines cannot be ignored. Next, let's take a look at how to carry out polyurethane. Cleaning of spraying equipment.
The first is the heating pipe of the polyurethane spraying equipment. When there is a certain pressure in the pipe, the moisture in the air is not easy to enter the pipe of the polyurethane spraying machine. Therefore, in order to ensure that the polyurethane raw material is not affected by the humid air, and the A material will not deteriorate or crystallize in the pipe, it can be The equipment is depressurized. This method is very helpful to maintain the equipment during the daily use of polyurethane spray equipment.
The second aspect is the A material suction pump of the polyurethane spraying equipment. In order to prevent the isocyanate component from reacting with the moisture in the air, causing the slowing down of the feed rate, the imbalance of the pumping ratio, and the occurrence of cavitation in the proportional pump. Therefore, after the equipment is used, clean the surface of the lifting pump with a cleaning agent, and put it into a protective sleeve containing the host cleaning agent to seal the lifting pump.
The third aspect, of course, must not forget the cleaning of the entire polyurethane spraying equipment. If the construction interval reaches more than 30 days, the entire A material system must be thoroughly cleaned and sealed to avoid affecting normal use next time.
Polyurethane foaming process, foam shrinkage, crispy, too soft, heartburn, cracking, smoke and other problems, how to analyze what causes.Polyurethane foaming process by the construction conditions, foaming equipment, construction technology and the impact of environmental temperature, there will be
The common ones are high pressure spraying, polyurethane spraying, hybrid spraying, and polyurea spraying. The construction industry usually uses high pressure sprayers, mostly for industrial production.High-pressure polyurethane spraying machine types:1, from the material of the spraying material i
Polyurethane foaming machine began to appear in foreign countries, with the ease of use and high efficiency by the production industry, and to be widely promoted and used. The polyurethane foaming machine directly determines the quality of the foam produced, even if the quality of the blowing agent
On April 12, CNMC-E3 polyurethane spraying machine was loaded in the industrial park and will be exported to France soon.CNMC-E3 polyurethane spraying machine is widely used in industrial maintenance, tunnel, subway, waterproofing of road base, production of foam film and television props, pipeline
Due to the demand of the production scale, many manufacturers will choose small polyurethane infusion foaming machine to help products for foaming, which can be more convenient for bonding, and in the subsequent use of the process is also more convenient for maintenance. So what are the characterist
Spring Festival does not close, for this year's Spring Festival holiday, CNMC Machinery's Ali International Station store got a good start. We started the year with a salesman, we harvested more than 1.4 million in sales, of which the largest single order reached one million.CNMC Machinery is a subs
Polyurethane sprayers may require special coatings and construction parameters when working with certain specialized types of wood. The following are some common types of specialty woods:
