What is self tapping screwUpdate Date:[2020-05-20]
Generally, it refers to the wood screws with sharp head, coarse teeth and hard texture, as well as aluminum alloy and plastic. A special self tapping screw for tapping metal holes is called a tap. Self tapping screw is used for non-metallic or soft metal, without bottom hole and tapping; self tap...Type of nutUpdate Date:[2020-05-20]
Nuts are the parts that connect the mechanical equipment closely. Only nuts and bolts of the same specification can be connected together through the inner thread. For example, m4-p0.7 nuts can only be connected with m4-p0.7 series bolts (in nuts, M4 refers to the inner diameter of the nut is about 4mm, 0...Purpose of screw steelUpdate Date:[2020-05-20]
Purpose of screw steel: screw steel is widely used in building, bridge, road and other civil engineering construction. As far as the public facilities such as highway, railway, bridge, culvert, tunnel, flood control, dam, etc., as well as the foundation, beam, column, wall, slab and screw steel of housing ...Hot dip galvanizing process and relevant instructionsUpdate Date:[2020-05-20]
Technological process workpiece → degreasing → washing → pickling → washing → dipping auxiliary plating solvent → drying and preheating → hot galvanizing and hot galvanizing → finishing → cooling → passivation → bleaching and hot galvanizing and washing → drying → inspection of relevant technological ...Technical difference between hot galvanizing and cold galvanizingUpdate Date:[2020-05-20]
Technical differences between hot galvanizing and cold galvanizing: The corrosion resistance of hot galvanizing is much higher than that of cold galvanizing. Hot galvanizing will not rust in a few years, cold galvanizing will rust in half a year! The cold galvanizing process is used to protect th...What is the performance of nutUpdate Date:[2020-05-20]
There are many kinds of nuts. Now let's talk about the hydraulic nuts in detail. What are their performance advantages? The hydraulic nut is an advanced bolt fastening system, which has the same working principle as the hydraulic stretcher. It is mainly used for the fastener assembly in narrow spac...Production process of screw steelUpdate Date:[2020-05-20]
Rebar is the surface ribbed bar, also known as ribbed bar, usually with two longitudinal ribs and transverse ribs evenly distributed along the length direction. The shape of transverse rib is spiral, herringbone and crescent. Expressed in millimeters of nominal diameter. The nominal diameter of ribbed bar ...Common factors affecting the speed and quality of galvanizingUpdate Date:[2020-05-20]
In the actual production process, the common factors affecting the speed and quality of galvanizing are as follows: (1) The pretreatment is not complete. There is oxide film on the surface of the workpiece, which affects the normal deposition of zinc. (2) Poor conductivity. The current is con...Type of surface galvanizing of steel plateUpdate Date:[2020-05-20]
Cold galvanizing Cold galvanizing, also known as electro galvanizing, is the use of electrolytic equipment to remove oil, pickling, and then put the pipe into a zinc salt solution, and connect the negative electrode of the electrolytic equipment, place a zinc plate on the opposite side of the pipe, connect...Main purpose of studUpdate Date:[2020-05-20]
