Plastic floor is another name for PVC floor. The main component is PVC material, and PVC floor can be made into two kinds, one is homogeneous infiltration, that is, the pattern material from the bottom to the surface is the same. There is also a composite type, that is, the top layer is a pure PVC transparent layer, and the printed layer and foam layer are added below. "PVC floor" refers to the floor made of PVC material. Specifically, PVC and its resin are used as the main raw materials, and fillers, plasticizers, stabilizers, colorants and other auxiliary materials are added, which are produced on a sheet-like continuous substrate through a coating process or a calendering, extrusion or extrusion process. Formally, it can be divided into two types: coiled floor and thin floor; The so-called coiled material floor is the floor with soft texture. Generally, its width is 1.5 m, 1.83 m, 2 m, 3 m, 4 m, 5 m, etc. The length of each roll is 7.5m,15m, 20m, 25m, etc. , with a total thickness of1.6mm. There are many specifications of board floors, which are mainly divided into strips and squares. There are two main types in structure: compound type and homogeneous type, and one is semi-homogeneous type; The so-called composite PVC floor refers to its multi-layer structure. Composite coiled material is generally composed of 4~5 layers of structure, including wear-resistant layer (including UV treatment), printed film layer, glass fiber layer, elastic foam layer and base layer. Composite sheets are generally laminated by 3-4 layers, generally including wear-resistant layer (including UV treatment), printed film layer, stable layer and base layer. Homogeneous PVC floor, whether coiled material or plate, is homogeneous from top to bottom, that is, from top to bottom, it is the same material and the same color.
