Cement bonded particle boards: sizes, prices and other parameters
The prices of cement bonded particle board for leaf at retail are defined depending on its sizes. In production there is so-called standard dimension of cement bonded particle board which makes 3200×1250 mm. At the same time thickness can vary from 10 to 40 mm.
Permissible deviations in size indicators (both width, and product length). The plate is thicker, the bigger deviation is allowed both towards increase, and towards reduction. So, for panels 10 mm thick maximum deviation makes 0.6 mm; 12–16 mm – 0.8 mm; 18–28 mm – 1 mm; 30–40 mm – 1.4 mm. However the total indicator of error should not exceed 3 mm on one product.
In addition to the cement bonded particle board sizes, there are also other technical indicators for which finished products are without fail tested, for example:
- at normal humidity, density of plate should not exceed 1300 kg/m²;
- the indicator of water absorption should not be more than 16%;
- at air humidity from 6 to 12%, cement bonded particle board should not inflate more than for 2%;
- durability of ready plate on stretching should not be less than 0.4 MPas;
- for bend the following norms are provided: for panels 10-16 mm thick – 12 MPas, 18–24 mm – 10 MPas, 26–40 mm – 9 MPas.
State standards regulate everything, including even plate surface roughness degree. The maximum allowed indicator of roughness for panels which have undergone processing on the grinding equipment makes 80 microns. And for the raw plates the limit is provided in 320 microns.
Helpful advice! Many producers provide considerable discounts for wholesale buyers therefore it is better to count in advance how many material you are required and to make the order once.
