Polyurethane phenolic insulation board equipment production process

Date: 2017-03-24

Share to:

Polyurethane phenolic insulation board equipment is a new type of building materials equipment, the main production process is feeding, mixing, injection molding, foam foam, the following look at the specific introduction.

①, feeding, mixing: through the feeding system will be quantitative cement, foam agent, foam stabilizer added to the mixer, dry mix for 30 seconds.

②, stir: the amount of warm water into the mixer, wet stirring for 2 minutes; the amount of the blowing agent into the mixer for 8-15 seconds.

③, injection molding, foaming: Immediately into the mold into the mold foam, foaming process about 3-5 minutes.

④, stripping: foam insulation board to be completed to complete the initial coagulation, with the initial strength can be stripped.

⑤, cutting: with a certain strength of the foam insulation board blanks after stripping can be cut, cutting specifications according to the need to adjust the cutting blade.

⑥, the initial maintenance: After the completion of injection molding for several hours after the initial maintenance.

⑦, finished product conservation: foam cement insulation board maintenance age should not be less than 7 days.

The elongated shaft machining supplier tells you the advantages of the hollow shaft

2017 - 03 - 22

Hollow shaft is more and more people to use, then let's talk about what the advantages of what you loved by everyoneHollow shaft occupies a relatively large volume of space, but can reduce the weight. According to the mechanical analysis of materials, in the shaft transmission torque, from the radial section to see, the more the place outside the effective torque transmission effect. In the shaft need to pass a larger torque, you need a thick shaft diameter. And because the role of the torque in the axial parts of the smaller, so the general use of hollow to reduce the weight of the shaft.

Continuous casting roll manufacturers to remind you must consider the oxidation of wire

2017 - 03 - 22

The wire must be considered for oxidation, in order to prevent the formation of plastic deformation is not uniform to avoid failure in the course of the operationAs the protective gas oxidation increases, the amount of deoxidized elements (such as silicon, manganese, titanium, etc.) in the wire increases correspondingly, and the strength of the weld metal is reduced. When the deoxidation element in the wire contains the most insufficient, causing the weld toughness to decline, but also may lead to welding defects (such as pores, etc.) generation.Welding hot-rolled steel, normalizing steel and ...
