1. Briefly describe the comparison between PVC floor and rubber floor?
Composition and production process are different: rubber floor is divided into homogeneous and heterogeneous. PVC floor, such as home, hospital, school, office building, factory, public place, supermarket, business, etc“ “PVC floor” refers to the floor made of PVC materials. The main component of plastic floor manufacturer is PVC material. PVC floor can be made into two kinds. One is homogeneous, that is, the material of pattern from bottom to surface is the same.
Stone plastic floor is a high-quality, high-tech research and development of new floor decoration materials, using natural marble powder to form a high-density, high fiber network structure of the solid base, the surface covered with super wear-resistant polymer PVC wear-resistant layer, after hundreds of processes. Homogeneous rubber floor is a kind of vulcanized floor with single layer or multi-layer structure, which is mainly made of natural rubber or synthetic rubber and has the same color and composition; Heterogeneous rubber floor is mainly natural rubber or synthetic rubber.
Color difference: color rubber floor more difficult, because the rubber has a strong absorption color, which is relatively single, most color rubber floor; PVC floor and color is very much, arbitrary combination, can provide more choices for designers.
The difficulty of installation is different in different degrees: PVC floor is light, easy to install and use; The rubber floor is very heavy, so it is difficult to install one. And the installation method of rubber floor can require students to be more strict. If the teaching method is wrong, there will be bubbles, and the requirements for self leveling foundation are more perfect, otherwise the defects of the base will be exaggerated.
Market demand and poor wear resistance: due to the high price, rubber floor is only used in some high-end places, such as hospitals, high-speed railways, power stations, aircraft boarding bridges, stations and other places. Use in a narrower range; And PVC floor because of its high cost, so it is widely used, huge market potential. Also wear rubber floor stronger, it is suitable for a large number of airports, stations and other high traffic websites, as well as airplanes, trains, subways, cars, ships and other vehicles.
2. Quality management requirements of PVC flooring products
2.1 When glue is applied, the indoor environment temperature must be higher than 10 ℃, otherwise construction is forbidden. When the temperature is higher than 10 ℃, the glue drying time shall be determined according to the specific working temperature of the enterprise.
2.2 all applicators must be applied and spread evenly.
2.3, and reasonable uniform cutting.
2.4. The slotting speed is uniform and straight without burr.
2.5 before welding, clean up the excess glue or other sundries in the welding groove.
2.6. The welding line is smooth and straight.
2.7. For the first time, the removal of redundant welding rod must wait until the temperature of welding rod is slightly lower.
2.8 during the laying of PVC floor coil, the students must be able to keep the site clean, closed, weatherproof and keep a certain temperature of the enterprise within at least 48 hours before and after the laying.
2.9 the relative humidity of indoor environment shall not exceed 60%. The technical conditions of material storage are the same.
2.10. Roll PVC floor up and down and label it. Make sure the color, capacity and batch number are clearly marked.
2.11. For materials with multiple rolls of the same product color, those with the same batch number shall be laid in the order of roll number. Use multiple batches of materials, pay attention to students not to lay materials with different batches in parallel.
2.12. Materials should always be arranged in alternate directions to avoid color difference at the seams.
