High speed shutter door is a rapid operating, anti-crash shutter door for indoor application . The most advantage of this door is that the opening/closing speed can reach to 0.6-1.8m/s, really fast action a lot than tranditional rollling shutter door. short opening and closing times reduce cooling loss, avoid airflow and enable a smooth operating procedure. They can also be designed in larger dimensions for the mining and aircraft industries.
High speed door can be easily installed, economical,quiet and efficient with electromechanical drive.
This door quickly though in/out open gate, ideal for warehouses,factories, hangars use, widths can be from 2m to 20 meters.
The material of this door are variety: PVC curtain to keep the insdie clean, heavy duty aluminum door with wind-resisitant function can wrok in heavy windy weather, and also the freezer door can be used in cold warehouse or somewhere like that.

Its characteristics: Oatmeal is a selective pre-emergence soil treatment agent. When germinated through the soil layer, the oatmeal is mainly absorbed by the bud sheath or the first cotyledon and is transmitted in the body. The growth site is the most sensitive, inhibiting the biosynthesis of fatty acids, and the top of the bud sheath is hollow. The dead oat can not be unearthed. And death; and the wild oats after emergence, absorbed by the roots, the wild oats after the poisoning of the drug, stop growing, the leaves are dark green, the heart leaves dry and die. Because of its strong volatility, its vapor is also toxic to wild oats. It should be mixed in time after application, and it is mainly decomposed by soil microorganisms in the soil. Applicable crops are mainly wheat, as well as beans and beets.
Control object: single wild oatmeal.
How to use: Mainly used in wheat fields. It is safer for wheat. Before planting, the ground is leveled with 40% emulsifiable concentrate 150-200ml/666.7 square meters, and water is 30~40kg, evenly sprayed on the soil surface, or mixed with soil; 40% emulsifiable concentrate 200ml/666.7 square meters, sprayed with water, immediately after application, shallow mixed soil 2~3cm, it is better to not cultivate wheat seeds, or mix 40% emulsifiable concentrate 200ml/666.7 square meters, apply , but with the application of water with water.
Note: The drug has high activity on oatmeal, good herbicidal effect, and 70~80ml of active ingredient per 666.7 square meters before seeding, and 80~90ml of effective ingredient in 666.7 square meters in seedling stage and autumn application. Because of its volatility, it needs to be mixed with the application of the drug, such as mixing soil after 4h interval, the herbicidal effect is significantly reduced. The depth of sowing is closely related to the efficacy and phytotoxicity. If the wheat seeds are directly exposed to the drug in the drug layer, it will also cause phytotoxicity to the wheat.
Use the medicine to remove wild oats from the wheat field
In addition to the chemical reagents of oatmeal - oatmeal, also known as wild wheat, wild swallow and so on.
