The production process of the XPS extruded foam board is not complex, but in order to ensure that the final processed plate conforms to the national standard or industry standard, so as to realize the optimal application and long-term application of the plate, the thermal insulation material of the XPS extruded foam board needs the manufacturer to pay more attention to the production link of the plank. Next, let's introduce the matters needing attention during the production of the XPS extruded foam board.

XPS Foam Board


Pay attention to the extrusion process

In order to improve the competitive advantage, the XPS extruded foam board manufacturers need to have a certain competitive advantage and improve the quality of the plate, which requires effective control of the quality of the plate, which can start from its production technology. the XPS extruded foam board is made through the extrusion process, and the effective control of this link can realize the quality control of the XPS extruded foam board.

The selection of high-quality raw materials is very important to the quality of the XPS extruded foam board. Manufacturers need to ensure that standard plastic materials are used.


Add flame retardants

XPS extruded foam board in the production process, but also pay special attention to the addition of flame retardant, because the XPS extruded foam board is very prone to fire accidents, so in production, but also add flame retardant, effectively organize and delay the violent combustion of the plate, now, the state has also issued a corresponding policy, there is no flame retardant XPS extruded foam board is not allowed to use.


Grooming treatment

In the production process of the XPS extruded foam board, we should also pay attention to peeling and fuzzing treatment, the main purpose of this link is to improve the adhesion of the whole system and release internal stress.

In the process of processing and production, the XPS extruded foam board also needs to be peeled and haired before it can be applied and installed, and peeling treatment is very necessary. The epidermis of the ordinary XPS extruded foam board is smooth, and the stickability of the plastering mortar and adhesive is very poor, so it needs to be peeled and haired. Next, let's introduce the two main purposes of the exfoliated board.


Improve the adhesion of the system

When the XPS extruded foam board is processed, it needs to be peeled and haired, and there are two main purposes in this link. The first purpose is to make the surface roughness of the plate convenient for pasting, and greatly improve the tensile bond strength of the plastering mortar and adhesive. at the same time, it can also improve the freeze resistance and water resistance of the XPS extruded foam board, and greatly improve the bonding strength of the system. Peeling can increase the surface roughness of the XPS extruded foam board and improve its adhesion to other materials, such as adhesives or coatings.


Release internal stress

The second purpose of peeling the XPS extruded foam board is to release a certain amount of internal stress, which can effectively avoid internal quenching in the long-term application, thus reducing the thermal insulation performance of the plate and affecting the normal use of the plate.

Through the above content, we can see that the two main purposes of peeling and depilation of the XPS extruded foam board are to improve the adhesion of the system and release the internal stress. therefore, it is very necessary for this kind of plate to carry out full peeling and depilation treatment.

Heat may be generated in the process of peeling and depilation, which can reduce the surface temperature of the XPS extruded foam board, thus preventing the sheet from deformation or warping.
