With the national environmental protection control policy is becoming more and more strict and the general trend of the national development of green building materials, the development space of gypsum products will be further increased, gypsum-based self-leveling mortar as a green building material, very in line with the policy of circular economy and sustainable development, the future market potential is huge.
Gypsum-based self-leveling is an ideal material for accurate leveling of the floor of buildings, and is suitable for the interior living room and bedroom of new, reconstructed and expanded civil buildings. It is mainly used for ground floor leveling, floor heating backfill, etc., and can be used to lay wooden floors, carpets, tiles and other ground decoration materials on its surface.
Gypsum-based self-leveling advantages:
1) The thickness of a single construction is 10-40mm, the surface flatness is high (less than 3mm 2m), and the fine leveling greatly reduces the arching phenomenon after laying wooden floors and other materials
2) No cracking, no hollowing, high strength, firm bonding, can solve the large area of wood floor and other ground decoration materials
3) Fast curing, high construction efficiency, can greatly shorten the construction period;
4) It has heat insulation, sound insulation, spontaneous breathing and excellent antibacterial properties, and is suitable for floor heating system
5) Prefer neutral materials that are friendly to the human body, safe and environmentally friendly.
Frequently asked questions about gypsum-based self-leveling mortar on the market:
Gypsum-based self-leveling surface stomata cause analysis:
The sealing effect of the interface agent is not good, and the interface agent is missed when brushed, and it is applied thinlyThe raw ground absorbs water quickly and dries;The amount of defoamer in the product itself is insufficient or improperly selected.
Cause analysis of low water leakage and intensity:
The construction water consumption is large, the moisture content is high after hardening, and the water is difficult to volatilizeGypsum self-leveling products have a low tolerance to water addition;The coagulation time is too long, resulting in a decrease in strength.
3) Cracking. Cause analysis: the quality of the self-leveling product itself, the shrinkage control is not good;Before construction, the base layer was not properly treated, the ground was not cleaned and there was dust, and the original base had cracks and was not repairedThe base layer under the insulation board is not leveled, and the insulation board or plumbing pipe is not fixed, and it is in a floating stateImproper maintenance after construction, pay attention to ventilation, close the entrance and exit of the site, and do a good job of protecting the finished product.
4) Mold. Cause analysis: gypsum-based self-leveling mortar has high moisture content, and water is difficult to volatilizeThe industrial by-product gypsum is untreated and the impurities exceed the standard.
In response to the above problems, Oriental Yuhong Sand Powder Technology Group has taken a series of measures to improve. The gypsum self-leveling mortar products launched are produced by high-quality desulfurized gypsum, which is green and environmentally friendly, with excellent performance, which meets the production needs and the trend of green development. At the same time, the use of high-quality supporting products and standardized construction processes can effectively ensure the professionalism and accuracy of the construction process.
