Selection of silo lining board
At present, in power plants, steel mills, coal mines and other kinds of silos, in order to prevent the bonding of materials, arch bridge and lead to poor cutting, blocking, lining board is generally installed in the silo. The lining types are: cast SLATE, microcrystalline board, nylon board, stainless steel board, ultra high molecular weight polyethylene board (UHMW-PE) and so on. However, because the manufacturers do not know the advantages and disadvantages of various lining boards, it is often difficult to draw a good conclusion about which type of lining boards to purchase. Therefore, according to our years of practical experience in the market service, solemnly recommend to you: choose ultra high molecular weight polyethylene lining board as a variety of silo lining board, is your first choice. At this point, we make a comparative analysis from the following aspects, for reference only.
I. Selection of raw materials and forming process of various lining boards and location of some manufacturers
1, cast SLATE: this product is a kind of mineral soil raw material, after melting into liquid at high temperature, pouring into blank plate, and then grinding molding. Its manufacturer is concentrated in the area that has raw material of production pottery and porcelain more.
2, microcrystalline plate: this product is the use of quartz sand after smelting glass, the remaining slag liquid pouring into blank plate, and then polished finishing molding. Its manufacturer is currently only next to xingtai glass factory.
3 nylon board: this product is selected in the nylon class of a called "oil-containing nylon" raw material, after melting into liquid temperature, pouring pressure molding. As far as WE know, there are only two. A family in Tangyin, Henan, and a family in Zhangjiakou, Hebei.
4, stainless steel plate: select the stainless steel plate sold on the market as lining plate raw material. No molding, can be directly welded. They are sold everywhere.
5, ultra high molecular weight polyethylene board: polyethylene plastic in all aspects of the better, the relative molecular weight of more than 1.5 million ultra high molecular weight polyethylene as raw material, because of its melting state lower limit flow speed is zero, can not be extruded, can not be injection molding so can only depend on calcination molding. The manufacturers are not more than 100, mostly in Henan Tangyin.
6, other: in addition to the above five kinds of regular liner on the market at present, there are all kinds of plastic plate, the plate, they, in the foreign sales are generally in "ultra-high molecular weight polyethylene lining board" or to referred to as "the banner of" polymer lining board ", induced by the user, the user mistaken for ultra-high molecular weight polyethylene liner. In fact, these are fake and shoddy products, they choose recycled plastic or such as: ordinary polyethylene, polypropylene, PVC and so on can not be used as lining board raw materials, after extrusion processing molding, disrupt the market, harm users.
As mentioned above, we seem not to see the advantages and disadvantages of various material lining board, but from the selection of raw materials, the way of forming and the number of manufacturers, we are not difficult to see the choice of nylon board, ultra-high molecular weight polyethylene board, stainless steel plate as lining board use must not be questioned.
