The effect and requirements of each layer of the surface are different, and the mortar used for each layer is different. At the same time, the characteristics of the base material and the engineering parts are different, and the technical requirements of the mortar are different. This is also the main basis for selecting the type of mortar. Cement mortar should be used for parts with high humidity or high strength; mixed mortar is mostly used for indoor bottom or middle or surface plastering;...
Japan's Oji Paper Co., Ltd. has successfully developed a high-compression rate molding paper for making food containers, and plans to produce 2,000 tons per year after two years. This high-compression profile paper is made from specially selected wood raw materials and is made from wood pulp with a unique pharmaceutical formulation. It is understood that, compared with general food container paper, the new high compression rate forming paper can be stretched and processed even after being...
At present, the valve has become one of the fastest growing industries in China's equipment manufacturing industry. The types of valves are constantly increasing, and the requirements of various industries for valve quality and technology are also getting higher and higher. However, like most of the machinery industry, China's valve industry is also facing the bottleneck of the late start, the bottom of the poor development. Enterprises in the procurement, most of them are more inclined to...

(A), the valve used on the water supply pipeline, the general principle of choice according to the following: 1, the diameter is not more than 50mm, it is advisable to use a stop valve, pipe diameter greater than 50mm gate valve, butterfly valve. 2, need to adjust the flow, water pressure should be used when the control valve, globe valve. 3, requiring a small flow resistance parts (such as the pump suction pipe), should adopt the gate valve. 4, the flow should be two-way flow of pipe sections...
The thermal insulation masonry cast-in-place bearing wall system is a new type of thermal insulation load-bearing structure, which first appeared in Europe and the United States. After the introduction of the building technology into China, it was valued by the construction industry. The thermal insulation masonry cast-in-place bearing wall system is constructed by the factory to produce the thermal insulation hollow block into a wall body, and the vertical and horizontal steel bars are...
Newly designed and installed control system, in order to ensure that the regulating valve can work normally while driving and make the system run safely, the new valve should be checked whether the nameplate mark on the valve accords with the design requirement before installation. The following items should also be debugged. Basic error limit; full stroke deviation; backlash; dead zone; leakage (in demanding occasions). If the original system is overhauled control valve, in addition to the...
Analysis of the Causes of Shock Pattern in Injection Moulding Products The surface of a rigid plastic part such as PS near its gate is densely corrugated centered on the gate, sometimes referred to as a grooving pattern. The reason is that if the melt viscosity is too large and the mold is filled with stagnant flow, the material at the front end will quickly condense and shrink as soon as it comes into contact with the surface of the cavity, while the subsequent melt expands and expands the...
Pulp mouldings are a new type of packaging material produced from pulp as a raw material and are widely used for the inner packaging of various products. The production process of pulp molding products is divided into three processes: slurry processing, vacuum forming and thermal energy drying. The energy consumption of the drying process occupies a large proportion in the entire production cost. How to reasonably determine the drying process conditions and reduce energy consumption is a key...
Many different types of casting press molding method customarily divided into: ① ordinary sand casting, including wet sand, dry sand and chemical hardening sand three categories. ② special casting, press molding materials can be divided into natural mineral sand and gravel as the main form of special casting material (such as investment casting, cement casting, foundry shell casting, vacuum casting, solid casting, ceramic mold casting etc.) and a metal as the main material of special casting...
