Many large-scale PVC coil floor projects will provide technical parameter tables, which are classified into many categories, so what are the main technical parameters? PVC coil floor mainly consists of two types of floor, one is homogeneous permeable PVC floor, the other is multilayer composite PVC floor. This paper mainly introduces the technical parameters of the two types of floor.

Technical parameter table of homogeneous permeable floor

The main technical parameters of homogeneous permeable floor are: weight parameter, thickness parameter, wear grade parameter, surface treatment parameter, fire grade parameter, tovc emission, etc. The weight parameter refers to the weight per square meter of PVC floor. The lower the weight, the higher the PVC content and the better the wear resistance. The wear-resistant grade is divided into t, P, m, F and T, which is the highest wear-resistant grade. At present, the wear-resistant grade of products from many small manufacturers can not reach T. among the domestic homogeneous and permeable floor manufacturers, Da Julong is one of the few manufacturers that can produce T-class wear-resistant products. There are also many surface treatment parameters, such as: put iodine wine, iodophor and other chemical reagent treatment, shoe printing resistance treatment, stain resistance treatment, the surface treatment of all brands are different. Most of the fire rating parameters require Class B1. Many small manufacturers fail to meet the requirements. Tovc is a total organic compound, mainly including hydrocarbons, halogenated hydrocarbons, oxygen hydrocarbons and nitrogen hydrocarbons. It includes benzene series, organic chlorides, freon series, organic ketones, amines, alcohols, ethers, esters, acids and petroleum hydrocarbon compounds, which do great harm to pregnant women and children. Therefore, tovc is an important technical index of various products.

Technical parameters of multilayer composite

The most important technical parameters of multi-layer composite floor are thickness parameters: there are many kinds of multi-layer composite floor thickness, 2.0mm, 2.2mm, 2.6mm, 2.4mm, 3.0mm, the most used is 2.0 thickness. Wear resistant layer parameters: 0.3mm,. 035mm, 0.4mm, 0.5mm, 0.6mm. Many cheap products do not meet the wear-resistant layer thickness standard, and most big brands are guaranteed. Fire rating: B1 is the standard required by most projects, wear rating: T, in theory, as long as the floor has a pure PVC wear-resistant layer, it can reach t wear-resistant. TVOC emissions, multi-layer composite PVC floor emissions are less than 100 micrograms.
