Hardware doors and windows are moving towards energy conservation and environmental protection

Hardware doors and windows are moving towards energy conservation and environmental protection China's doors and windows industry has experienced wooden doors and windows, aluminum alloy doors and windows, steel doors and windows after several stages, but also to follow the trend of the times, is moving toward the direction of energy conservation and environmental protection.

Plastic steel doors and windows by virtue of its thermal insulation, sealing noise, corrosion resistance, anti-aging, elegant appearance and other advantages, welcomed by the people. At present, plastic steel doors and windows are the most commonly used products. Wooden doors and windows can lead scenery, ventilation, sound insulation, and coordinate interior decoration, and are gradually becoming the mainstream of high-end windows and doors. Aluminum alloy doors and windows are moving toward high-grade energy-saving and soundproofing. Steel doors and windows are gradually being eliminated due to poor overall performance.

Building materials industry analysts believe that green environmental protection is becoming popular and the development of energy-saving and environmentally friendly windows and doors is a huge business opportunity for the door and window industry. The painted doors, which can be processed and produced according to the needs of different users, have been sought after by younger groups and have also improved the decorative quality of the doors. In terms of function, consumers have put forward higher and stricter requirements for the insulation of windows and doors, and protection against ultraviolet rays. China is adopting a series of measures to control the excessive growth of high-energy-consuming and high-polluting industries. Doors and windows procurement will also be biased toward new types of high-value-added products. The birth of a large number of low-carbon and energy-saving building materials will promote the development of the door and window industry in China. More rational development.

With the continuation of industrialization and the increase in personal business income, the health benefits in the construction industry will promote the increase in the demand for doors and windows. At the same time, national government departments have repeatedly issued new policies for building energy conservation, and provinces, cities, and autonomous regions have also formulated local architectural design standards. In this case, the door and window industry has accelerated the pace of technological innovation, product upgrading, and quality improvement, and has introduced more new types of environmentally friendly and energy-saving products to the community.

 Our key products are litharge using in assaying of precious metal, and lead nitrate using in gold mining. Lead nitrate is used as medical astringent; tanning material for leather-making; dyeing mordant; photograph promoting agent; flotation for ore; chemical reagents; and also used for making fireworks, match, and other lead salts. In the mean time, we are sourcing the other chemical reagents for our mining customers in Australia, Canada, Africa etc.

1. Product name:lead nitrate

2. Character: white crystal powder, relative density 4.53(20), easily soluble in water, liquid ammonia, light dissolve in ethyl alcohol, not dissolve in concentrated nitrate acid, solubility 56.5g/100g water (20). Dry lead nitrate decompose at 205-223. Damp lead nitrate decompose at 100, first become Pb(NO3)2 . PbO, go on heating, then become PbO. It is strong oxidant, putting together with organics will lead it burning, noxious.
3. Application: Used as flotation reagent for gold ore and other ore.
