A screw is a very small and inconspicuous tool in our life. Although it may seem small, it’s really a working code that we can’t live without. It’s also a small job with a very important role and a lot of power. It has very flexible use effects, drywall screws have its own unique role in our lives. Now, as a product manufacturer, the overall quality of our drywall screws is very good and the overall quality is very good.
Screws are still a very important small tool in the whole construction project work. Without such a small tool, we can’t do all kinds of fixed work, all kinds of house decoration and house construction. Drywall screws and other small tools can be used together, with good surface setting effect and fixing effect. Without such a small tool, it would be difficult to talk about some of the wood pressure maintenance records in our home or summarize the various manufacturing thicknesses in our rooms. This is a very important tool for us.
Now our drywall screw manufacturer produces nails. The overall quality is very good, the corresponding quality is better, the convenient service life of the intuitive education body is longer, because now our cattle manufacturers have made a good improvement on the overall material, the corresponding product performance has been better improved, and our play has played a better use effect.
The price of drywall screws in the market now varies widely. Cheap drywall screws are just over 5,000 tons, while expensive screws are nearly twice the size of regular screws. Why are prices so different? Is it a change in the material or a problem in the production process?
Hot external treatment of dry wall screws is a method to change the problem of steel parts by different cooling methods. Now commonly used thermal external treatment has fire. All the fire and tempering, what effect do these three methods produce?
1. Drywall screw quenching: heat the steel to more than 942℃, so that the steel reflects the austenitic state, and then put in cold water or cooling oil quenching, so that the steel reflects the martensite property. This method of exposure increases the strength and hardness of the steel. The strength and hardness of sample grade steels vary greatly between quenched and unquenched steels
2. Drywall screw annealing: The same heat treatment method that heats the steel to austenitic state and then cools it naturally in the air. This method can reduce the strength and hardness of steel, improve the flexibility of steel, easy to process. Generally, steel goes through this step before being processed
3, tempering: whether quenching, annealing or pressure treatment, will produce internal stress in steel parts, and the imbalance of internal stress will affect the energy of steel structure and mechanical parts from the inside, so should be tempering treatment. The material is kept indoors at temperatures above 700 degrees to change its internal stress, and then cooled naturally.
