Oxygen shut-off valve maintenance 1. The purpose of maintenance is to extend the life of the oxygen shut-off valve and ensure reliable opening and closing. 2. The stem thread is often rubbed against the stem nut. It should be coated with a little yellow dry oil, molybdenum disulfide or graphite powder to lubricate. 3. The copper internal thread ball valve that does not open and close frequently should also rotate the hand wheel regularly to add lubricant to the stem thread to prevent biting. 4, outdoor oxygen shut-off valve , the valve stem should be protected to prevent rain, snow, dust and rust. 5. If the valve is mechanically moving, add lubricating oil to the gearbox on time. 6. Always keep the oxygen shut-off valve clean. 7. Always check and maintain the integrity of the other components of the oxygen shut-off valve . If the fixing nut of the hand wheel falls off, it must be matched and cannot be used. Otherwise, the square of the upper part of the valve stem will be ground, and the reliability of the fitting will be gradually lost, and it will not be able to start. 8. Do not rely on the oxygen shut-off valve to support other heavy objects. Do not stand on the oxygen shut-off valve . 9. The valve stem, especially the threaded part, should be wiped frequently. The lubricant that has been soiled by dust should be replaced with new ones. Because the dust contains hard materials, it is easy to wear the thread and the surface of the valve stem, which affects the service life.
Poly Gamma Glutamic Acid is a natural occurring, multi-functional, and biodegradable biopolymer. Agricultural Grade Poly-Γ-Glutamic Acid
is produced through fermentation by Bacillus subtilis using glutamic acid. Poly Gamma Glutamic Acid
is consists of glutamic acid monomers cross-linked between α-amino and
γ-carboxyl groups, and the molecular weight of PGA is usually between 100~1000
kDa. It is water-soluble, edible and non-toxictowards human, and is environment
friendly. It has broad applications in the fields of medicine, food, cosmetics,
and water treatment.
Applications
*Base Fertilizer:
Use
it about 10kgs for a unit of area, then irrigate with clean water or muck
water. Or irrigate amino acid together with water. Or fertilize with other
compound fertilizers, broadcast application, hole application both are ok. It
is applicable to all the crops.
*Foliar Fertilizer:
Dilute
it by 800-1000 times and spray directly. Also, it can spray by mixed with trace
element. Use 200-500g for a unit of area.
*Compound Fertilizer &
Irrigation Fertilizer:
It
can be added to compound fertilizer by rate of 5-8%, improve the nutrient
content of compound fertilizer, increases crops` direct absorption.
Advantage For Fertilizer Gamma-PGA
1.Easy
and high-efficacy absorption by plants.
2.Help
the absorption and the translocation of the nutrients in cells.
3.Improves
the immune system of the crops and increases their resistance against diseases,
severe weather.
4.Simulates
protein synthesis and gives strength to plants accelerating their growth
