The difference between potassium sulfate and potassium chloride

The appearance of potassium sulfate is white crystal or colored crystals or particles. It is characterized by low moisture absorption, is not easy to agglomerate when stored, and is easily soluble in water. Applicable to all kinds of crops, can be used as base fertilizer, top dressing, seed fertilizer and top dressing. The base fertilizer is generally 10-12.5 kg, the fertilization amount is 1.5-2.5 kg, and the foliar spray fertilizer is 0.5%-2%. Potassium is generally adsorbed by the soil and will not be lost. However, it is also necessary to adopt a “small amount of meals” on the sand with poor fertilizer retention capacity. Generally, it is best applied to potassium plants such as potatoes and melons. Wide range of use, large dosage.
The appearance of potassium chloride is white or light yellow crystal, sometimes containing iron salts in red. Soluble in water, it is a high concentration of quick-acting potash. It can be used as base fertilizer and topdressing. The amount of base fertilizer is 8-10 kg, and the amount of fertilizer is 5-7. The scope of application is smaller than that of potassium sulfate. Special attention should be paid to the use of chlorine-sensitive crops such as grapes, potatoes, tobacco and other crops to avoid "chlorine damage".
To correctly distinguish and use these two kinds of fertilizers, it should be noted that when purchasing potassium fertilizer, the first thing to look at is whether the appearance meets the above explanation; the second is to see the bag marking implementation standard, the potassium sulfate implementation of HG/T3279-1990 issued by the Ministry of Chemical Industry, chlorine The national standard GB6549-86 implemented by potassium, and the third can not simply consider the price, mainly depends on its nutrient content.

Angle Valves

Globe Valves and angle valves are designed for throttling or regulating flow in commercial and industrial applications. Bronze, cast iron, or cast ductile iron materials. Threaded, flanged, or solder end connections.

Angle valves for use in commercial and industrial applications. Typical services include hot and cold water, HVAC, steam, compressed air, gas and other general utility services.
Vacuum angle valve is used for turn on or shut off the airflow in the vacuum pipeline, the applicable media is air and non-corrosive gases.
It has two structures, one is angle type and another is a 3-way type within an ISO-KF or ISO-F various flange end pre-pump port.
a) Small diameter (≤DN50) valve body are precision investment casting.
b) Large diameter (> DN50) valve body are molding shaped seamless steel or steel plate.
c) Bellows sealed structure can withstand 150ºCtemperature, metal sealed structure can withstand 450ºCtemperature.
d) Can install on any position to control the airflow in the vacuum pipeline, as an on-off valve purpose
