Gypsum powder fineness and water absorption rate of the plaster mold life has an important impact. Gypsum powder is too coarse, the mold used for some time, due to corrosion, surface will appear coarse plaster mold factory lines, uneven surface of the mold, Liaoning plaster mold factory line, so the rough surface of the body, it affects the finished appearance, Heilongjiang plaster Mould plant lines, reduce die life; however, too small particles (specific surface area> 1500cm2 / g), since the crystals have a greater stress, strength decreases, also resulting in decreased die life, while the fine through fine gypsum mold poor water absorption. Proved: gypsum powder particle control about 80 percent of maintaining the same particle size and fineness of 120 mesh sieve is less than 1%, not only to the inner surface of the mold has a good feel, and a higher strength and better water absorption rate. Plaster mold is to produce gypsum plaster line and its other products produced by the mold, generally applied in the field of decoration. Accordance with the material is usually divided into glass fiber reinforced plastic material and silicone material two kinds. Whether or fiberglass mold silicone mold are use to produce raw material for plaster, gypsum powder and glass fibers and water, these three according to certain production processes to be processed into gypsum line. Also note that when you use do not damage the surface of the plaster mold with a hard object, as far as possible to avoid damaging the mold. Anhydrite and gypsum belong to the same rigid gas cementing material, after grinding process can also be used to make paint materials, gypsum board, masonry and other building materials. Thus in the cement industry, Henan plaster mold factory lines, both of which are produced can cement-coagulation agents, in order to regulate the cement setting Speed. Smooth level surface, it is because plaster mold relief decoration product design patterns, when you install the paint will not be able then scrub and other processing, so the surface finish requirements but also to a high degree. Only after that the surface is more delicate, smooth feel of plaster relief painting decorative product installation, it may be a good decorative effect. If the surface is rough, not smooth, installation painting after a certain feeling of giving a shoddy. Henan plaster mold factory lines, ARTEL plaster mold (online consultation), plaster mold factory lines provided by Gaomi Artel plaster mold factory.
