Both belong to PVC floor, the specifications and sizes are the same, and some parts are the same size;
Dry back mainly has eight specifications of 942*157, 1227*157, 1227*187, 1227*235, 914.4*101.6, 470*470, 608*308 (unit: mm);
Loose lay mainly has 942*157, 1227*157, 1227*187, 1227*235, 470*470, 608*308 (unit: mm).
Click mainly has 936*150, 1220*150, 1220*180, 1220*228, 1500*228, 600*300 (unit: mm). These specifications, pay attention to compare with dry back.
WPC currently has two specifications 1217*146, 1217*178, 596*296 (unit: mm).
SPC mainly has: 1210*150, 1210*181, 203*1219, 178*1219, 152*1219 (unit: mm).
A. Installation method: dry back requires the use of glue, etc., also known as glue down; loose lay directly on the pavement (loose lay bottom material is covered with black leather, placed on the plane can not move.)
B. Thickness: Dry back, our factory only starts from 2.0mm thick bottom. If it is lower than this specification, we can not make it. Loose lay is generally consistent with Click 4.0mm, 5.0mm
C. Wear-resisting layer: Under normal circumstances, we now do 2.0 mm and 2.5mm thick dry back, wear-resistant 0.1mm-0.5mm, 3.0mm thick dry back, wear-resistant 0.1mm-1.0mm, 2.0mm 2.5mm, in principle, we can do more than 0.5mm wear resistance, but it is not cost-effective. In addition, the formulation of the bottom material and the middle material have to be changed and tested. Now the factory basically does not do; Now, for the dry back, the wear layers of 4.0mm and 5mm are basically only wearable for 0.3mm and 0.5mm, for the same reason.
D. Price: dry back is cheap, loose lay is more expensive
E. Health time: dry back requires 24 hours to health after tempering. Loose lay is the same as the lock series, which takes 48 hours.
F: The flexibility of the two is different. The loose lay product is obviously much softer than the dry back. Such characteristics can also be used as a distinguishing feature. At the same time, the most obvious is that there is a layer of black leather at the bottom of the loose lay, which can be distinguished by soft and hard using a nail scraping test.
