The application prospect of calcium carbonate in stone plastic floor is broad. PVC floor is a new generation of floor decoration materials popular in the European and American home furnishing market. It was first born in Europe in the early 1960s, and was introduced to the United States in the 1960s. After decades of research and improvement in Europe and the United States, PVC flooring has been widely promoted and used all over the world. In Europe, the United States, Japan, South Korea and other regions, the application of PVC flooring has occupied more than 40% of the market share, and shows a gradual upward trend.
Application prospect of calcium carbonate in stone plastic floor
SPC is the abbreviation of stone plastic composite, which is literally translated as stone plastic composite. It is referred to as stone plastic floor, which belongs to a kind of PVC floor. Traditional lvtpvc flooring also contains stone powder used to enhance the stability of products, which can also be called SPC flooring, but its stone powder content is far lower than SPC products. There are also wood flour and PVC mixed, abbreviated as WPC wood plastic flooring. The products introduced in this paper are lock lock SPC products with high content of stone powder.
Advantages of SPC floor
Green environmental protection and zero formaldehyde
Healthy, green and environment-friendly building materials are people’s goal. The main source of formaldehyde in the floor is glue, most of the floor installation need to use glue, composite floor is made of glue, so the problem of formaldehyde in the decoration has been difficult to avoid. The reason why SPC floor can achieve zero methanol comes from its unique material and composition.
SPC floor is a kind of product made of PVC base material extruded by extruder combined with T-shaped mold, PVC wear-resistant layer, printing layer and PVC base material are respectively heated by calender for lamination and embossing at one time. The process is simple, lamination is completed by heat, and glue is not needed. The main material in the base course of SPC stone plastic floor is natural stone powder, which is tested by the national authority department. The material does not contain formaldehyde and any radioactive elements, which can provide a comfortable and healthy environment for residents.
Waterproof, antiskid, fireproof and flame retardant
SPC floor has strong waterproof performance. It solves the problems of mildew, arching and peculiar smell of traditional wood floor due to high humidity. Compared with PVC floor made of LVT sheet, the stone powder content of lock type SPC floor is higher, and paving without glue can effectively avoid the glue deformation caused by soaking in water.
When the SPC floor is soaked in normal temperature tap water for 24 hours, there is no bubble deformation on its surface, and its expansion rate is only 0.12%. Compared with other floor products, this expansion rate can be ignored. Therefore, the waterproof performance of SPC floor is extremely superior. The fire index of SPC floor can reach B1 level, second only to stone, and SPC floor itself will not burn, high temperature is not easy to deform, can effectively play a role in flame retardant.
Laminate flooring is one of the most wear-resistant materials in the flooring industry. The wear resistance of its aluminum oxide surface can reach more than 12000 rpm. According to the thickness of PVC wear-resistant layer, the wear-resistant degree of SPC floor surface is also different. The wear-resistant revolution of 0.55mm PVC wear-resistant layer can reach 12000-20000 revolution, which is stronger than lvtpvc floor with softer texture. Because of the superior wear resistance of SPC floor, SPC floor is more and more popular in hospitals, schools, office buildings, shopping malls, supermarkets, vehicles and other places with large flow of people.
Elastic recovery noise reduction
SPC floor has comfortable foot feeling, good elastic recovery and impact resistance, and is not easy to be damaged or sunken due to external impact. SPC products with cork cushion or EVA foam on the bottom layer can effectively absorb the impact force, so as to reduce the reaction force of the ground on the human body when falling. The cushion at the bottom has good sound absorption performance, which can effectively reduce the transmission of ground noise. The surface coating of SPC floor can inhibit the growth of bacteria, play an antibacterial effect, so that children and the elderly can better contact with the floor, comfortable and healthy.
Low expansion coefficient
Low expansion coefficient is the biggest advantage of lock type SPC floor compared with traditional floor materials, which can effectively avoid thermal expansion and cold contraction caused by external environment, and avoid floor deformation. Thanks to its low expansion coefficient, in the process of SPC floor paving, large area paving can be realized without reserving expansion joint. Traditional floor paving more than 8 meters need to install T-shaped strip, and stone plastic floor can achieve large area paving 400 square meters without T-shaped strip, and in the whole house paving, the door position does not need to install buckle strip.
