Exposed to moisture for an extended period of time, bamboo flooring products can absorb moisture and weaken. Because bamboo is grass, the grain runs the length of the board. Inferior or inappropriate bamboo selection, the use of bamboo that is either harvested too young or not properly dried can be prone to changes in temperature and humidity. This can lead to cupping, warping and swelling of the material.
1. Uneven distribution of floor moisture content
In the case of air drying, on the contrary, the board will bend like a slotted side.

Solutions
1. In production:
When health balance, drying should not be too fast, drying kiln to keep the temperature uniform;
Try to make sure that both sides of the floor have the same texture
2. How to avoid before installation
Proper expansion joints reserved for paving
3. After installation
Because the weather humidity changes with the season, you can see if the floor will recover in a few months. If it is still tile, you can only replace the floor

We all know that the raw materials of SPC flooring are mainly composed of plastic and stone powder, the content of stone powder is too small, the RIGID SPC FLOORING is not strong and the cost will rise, and too much stone powder will also cause the floor to be brittle and easy to break
Product sampling is very important, and the sampling standards affect the authenticity of the test results. The following are the latest sampling standards.
Main Specifications Layer: Multi Ply Edge: Micro Bevel/Bevel Moisture content: 7-9% Surface wood Layer: 0.3-6mm Length: 300-2200 mm Width: 90-300 mm Thickness:10/12/14/15/18/20 mm Finish:smoke/embossed/hand-scraped/brushed/sawing Joint: T&G/Click
QUALITY CONTROL STANDARD-WOOD PLASTIC COMPOSITE FLOORING OUTDOOR SCOPE This standard specifies the requirements of WPC floor for export, test methods, inspection rules and packaging, transportation and storage requirements. TECHNICAL REQUIREMENTS Size And Deviation Length 0~+10mm, Negative tolerance is not allowed Width ±1mm, the difference between the maximum and minimum values ≤3 mm Thickness thickness＜25mm， ±0.5mm thickness≥25mm，±1.0mm Tolerance on wall thickness ±0.5mm Structure wood plastic composite Bevel need negotiation by the Customer and factory Straight Angle ≤ 0.30mm Straightness ≤ 1.0mm Model of click should be the same as the confirmed steel model Note: No tongue WPC flooring does not required height difference and gap; If have tongue and groove, the width of tongue should be more than 3mm. For wpc flooring, the weight should be more than 95% of WPC weight which two parts agreed. WPC Flooring Appearance & Quality Requirements In addition to the design effect, the color should be uniform, the surface is flat, no scratch, no obvious concave and convex, the impurity, the end should be straight, no burr. Item Superior product Qualified product Color unmatching It is allowed if not too obvious Surface unevenness Not allowed It is allowed if not too obvious Split, crack Not allowed Spots,dirt and similar surface defects ≤4mm², allowable amount is 1pc/m ≤4mm², allowable amount is 3pcs/m Blister Not allowed Bubble Not allowed Trace grain Not allowed It is allowed if not too obvious Surface granular Not allowed It is allowed if not too obvious Incomplete sander-polishing Not allowed Tongue and corner deformity Not allowed The board face concave and convex is only used for judging the plane plastic wood floor WPC Flooring Physical And Chemical Performance Requirements Test Item Test method Standard Water absorption of 24h At room temperature, the immersion time of the sample was 24h±15min ≤2.0% State after heating( 120℃) (120±2)℃，(30+3)min No bubbles, cracks, pitting Size change rate after heating(100℃) (100±2)℃，(60+3)min ±1.0% Density ≥1.2g/cm³ surface abrasion resistance 100*100*1pc sample, install it on the wear tester.
