Many felt there bocay, manufacturers are also uneven in quality, in order to guarantee to buy good quality blankets, Xiaobian to summarize the following items to buy blankets to note, don't thank me, you happy for us to complete the mission. The first thing to say is that the weight per unit volume of the felt (g / cm3) is too large to lose its elasticity, and the unit volume is too small to wear out. Thickness, thickness and so on have a variety of performance, the use of units can be used according to the requirements of the appropriate selection, procurement is best to inform the product use, so as not to affect the use of production. Second, we must understand that the current variety of special felt felt blankets, general felt. The difference between varieties according to material thickness, the volume weight of unit size (i.e. compact bulk density) and color division: technical requirements are divided according to the difference between with and without strength, elongation, capillary action, the use of units can be selected according to needs. Inspection, this standard can be tested. The above is the Boke felt small to give attention to introduce the selection of felt, with it I believe we will not buy again at the. It is our pleasure to provide help for all of you!
