About daily methods to prevent damage to hardware

Hardware is a necessity for ordinary people in daily life, and it is also an indispensable building material in the modern construction industry. Whether it is door and window industry, plumbing industry, cabinet industry, furniture industry, decoration industry, etc., it will be widely applied to hardware products. Small hardware not only plays a very important role in these industries, but also has a very decorative effect. However, the damage of hardware has caused many consumers to worry. Sometimes it is better to buy the hardware, but after using it for some time, there are still some problems. So when we encounter such a problem, what should we do? In fact, the hardware also needs everyone's careful maintenance.

Teach you how to prevent daily hardware damage
The following small series has compiled a number of methods for daily hardware damage prevention: 1. The model, specifications and performance of the hardware accessories should conform to the current national standards and relevant regulations, and match the selected plastic doors and windows.
2. For sliding windows with a width of more than 1m, or doors and windows with double glazing, double pulleys or rolling pulleys should be used.
3. The sliding hinges shall not be made of aluminum alloy and shall be made of stainless steel.
4. To install the hardware with the fastening screws, a metal lining must be built in. The thickness of the lining should be at least twice the distance of the fastener. Do not fasten to plastic profiles or use non-metallic linings.
5, hardware accessories should be installed last, door and window locks, handles, etc. should be assembled after the window door fan is inserted into the frame to ensure correct position and flexible switch.
6, the hardware should be carefully maintained after installation to prevent rust and corrosion. In daily use, it is necessary to lightly open and close the door to prevent hard opening and damage.

3. Application
Printing and dyeing industry: mainly used for dyeing vat dyes suspension, leuco acid staining, dispersion and soluble vat dyes dyeing. Also be used for silk / wool interwoven fabric dyeing, the yarn is no color. Mainly used for industrial dye dispersion and diffusion of color lakes manufacturing additives.
Building materials industry: as early strength cement water reducing agent, the amount of 0.5-1% by cement after the shock has good dispersion effect, increasing the strength of cement. Diffused N of concrete tensile strength, impermeability, frost and compressive modulus of elasticity are improved, no corrosion of steel effect.
Pesticide industry: It can be widely used in wettable pesticides, with good dispersion and solubilization, can significantly improve the efficacy, dosage according to product requirements. Example: buprofezin, the amount of 3-5 %; thiophanate amount of 0.8-1.5 %, 0.8-1 % Kai Ling vegetables.
Electroplating industry: the color is added, crossing pigment dispersants N allows uniform dispersion can significantly improve the plating surface brightness, and the amount is usually 10% of the pigment.
Rubber industry: rubber (latex) of industrial production process, the dispersed substances such as sulfur accelerator, antioxidant zinc oxide fillers ( such as barium sulfate , calcium carbonate ), etc., added to the dry weight of a Dispersing Agent N2-4% , 10% Dispersant solution prepared in advance , and along with the other components in a ball mill grinding , can improve the dispersion effect and shorten the milling time .
Packing: 25kg bags.
Storage: two years and must be upload and download lightly.
