The Spiral door offers high-speed operation for high-traffic situations and rigid aluminum slat construction that eliminates the need for a second security door. Crisp lines give the Spiral door a stylish look that's great for many types of commercial, automotive retail, government, institutional and industrial applications. The Spiral is ideal for automotive dealerships, government, parking and security. Benefits No metal-to-metal contact reduces wear on the door panel and offers fast, quiet operation.
Aluminum spiral High Speed doors are usually used wherever goods traffic occurs and where the doors have to fulfill special requirements. In the food and beverage industry, or Medical industry for example, special climatic conditions have to prevail; 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.

If the drug precipitates slowly, the suspension is good. In case of poor quality, silicone additives or 0.10% neutral detergent should be added before use to increase wet spread.
If the wettable powder absorbs moisture and is hard, it should not be used as a spray.
If the powder powder absorbs moisture and agglomerates during storage, it needs to be placed in a cool and ventilated place to dry. Do not use it after sun exposure or crushing.
If the agglomeration is serious, it can only be used for toxic soil.
Dairy emulsions In the course of storage, if the storage is not good, the following three situations may occur:
Agglomeration. If the emulsified concentrate has a non-flowing viscous liquid or has formed a soapy solid, it proves that the solvent has been mostly volatilized and the quality has changed and cannot be used.
Precipitation crystallization. For long-term storage of the emulsion, there will be white crystals on the bottom of the bottle or turbidity. If the emulsified milk bottle is immersed in warm water of 30 ° C ~ 40 ° C, the crystallization can be dissolved in about 30 minutes, and it will return to a transparent liquid, indicating that the quality is still good and can be used. If it does not dissolve, it indicates that the quality of the cream has changed and cannot be used.
Changes in the emulsifying properties of the cream. Take 1 part of emulsifiable concentrate, add 200 parts of water, put it in a glass cup, shake it and let it stand for about half an hour. Observe the emulsification. If there is no oil slick in the upper layer, there is no precipitation in the lower layer, no obvious oil beads in the middle, indicating that the emulsification performance is good; There is emulsifiable concentrate, there is sediment underneath, and there is delamination after 10 minutes, indicating that the emulsion is destroyed and cannot be used.
Wettable powder Take 1 part of wettable powder, add 200 parts of water, hold it in a glass cup, shake it for a certain period of time, and observe the suspension.
