Post time: 05-01-23High quality galvanized wire in general, the zinc layer attached to the surface of the wire is relatively thick, so when we buy galvanized wire, as long as we look at the thickness of the zinc layer machine, we can generally judge whether the quality of galvanized wire is high quality.
The cooling circulation system uses spray to cool the drawing die, and takes away a lot of heat generated by the drawing machine in high speed drawing in time to ensure the quality of the wire. Control drawing process parameters: drawing speed 10 ~ 12m/s; Winding tension 8 ~ 10N; Measuring length 30km; The mass fraction of lubricant is 3.5 ~ 4.5%; pH value of lubricant 7 ~ 8; Lubricant temperature 30 ~ 40℃.
- If the requirements are not high, and the ventilation is good, and relatively dry place, it is recommended to use electric galvanized barbed rope, because the price of this product has a certain advantage, for ordinary users, this is a more appropriate product.
- The zinc layer on the galvanized wire has good ductility, can be cold blanking, rolling, bending and other molding without damage to the zinc layer. The zinc layer of galvanized wire with thick zinc layer has fine crystallinity, uniform and no void, and good corrosion resistance. The zinc layer obtained by electrogalvanizing is very pure and corrodes slowly in the gas, liquid and fog of acid and alkali, which can effectively protect the steel matrix. Galvanized layer can also be chromate passivation into a variety of colors, beautiful and generous, with good decoration.

The purchase of blade barbed rope also needs to consider the higher manual installation cost in the later period. Generally, customers only ask the price of blade barbed rope, and sometimes the installation cost is not taken into account in the budget, which is very unreasonable. Because the installation cost is not cheaper than the rope itself, sometimes even the blade rope and column combined. The blade stabbing rope needs a lot of manpower and material resources for installation. In general, the installation cost is also a relatively large expenditure item in the stabbing rope project.

3, with oil cloth (oil used cloth), carefully from inside to outside, including each cage wire repeatedly grinding many times. The front of the bird cage, the door flowers, where vision is often in place, are repeatedly rubbed in order to improve the surface finish, equivalent to “grinding”. Note: door flowers, arhat lines and other structures are delicate and fragile, do not break. This process, which requires time and patience, care, is also a process of observing and appreciating the cage. Use new cloth again, according to the above process, wipe again and again. This process is equivalent to polishing. For important parts, you can use a little force, the speed can be a little faster (do not use force). Be careful to fold the cloth neatly, otherwise marks will easily form. When this process is complete, the surface finish is significantly improved.

HPMC (Hydroxypropyl methyl cellulose) is a water-soluble polymer made from cellulose modified with hydroxypropyl groups. It is used as a thickener, emulsifier and stabilizer in foods, pharmaceuticals and cosmetics. HPMC is produced by treating methyl cellulose with propylene oxide. The end result is a white, odorless and tasteless powder. Hydroxypropyl methyl cellulose is very similar to methyl cellulose, but it is more soluble in water and has a higher viscosity. HPMC has many uses, such as a thickener (to replace cornstarch), a stabilizer (to prevent ingredients from separating or settling), a binder (to hold ingredients together), or an emulsifier (to mix two substances that do not dissolve well into each other).
- Understanding HPMC's solubility is critical for formulators and researchers. It helps in selecting the right grade and adjusting processing conditions to achieve the desired properties in end-products. The chart serves as a practical tool, simplifying the complex relationship between HPMC, solvent type, temperature, and particle size.
