Use salt sauce to prevent and treat 2.5% of salt, 2% of soy sauce, 1% of binder (flour can be used), add 50 kg of water, stir in the pan, boil for 10-15 minutes, and put it into the bucket for use (if one Use the remaining salt sauce to keep it sealed. After the affected area has been wiped clean, apply evenly with a brush, apply it once every 5 days, and continue to apply it 2 or 3 times.
Use vinegar to prevent the sickness from scratching with a knife first, then brush with vinegar and apply it on the new brush. Brush once every 7 days, and even brush 3 to 4 times to cure. If you vinegar in advance, the control effect will be better.
Use alkaline water to prevent alkali from 1 part and add 4 parts of water. After stirring well, use a brush to brush directly on the trunk. After the brush, the sickness is obviously exposed. First cut the sickle with a knife into a box of 1 cm in length and depth, cut the trace deep into the xylem, and then brush with alkali water. If you scrape the disease and then brush alkaline water better. Specific practice: In the disease period, brush once every 10 days, so that alkaline water penetration of the disease; in the recurrence of the disease, brush every 7 days 1, while regular inspections, timely detection of diseased trees found.
The above methods can be carried out throughout the year and are cost-effective.
Quartz Sleeve
We provide quartz sleeve for the uv lamp.
The quartz sleeves are probably the most abused components of a UV system, yet they are one of the most critical for delivering UV rays into the water stream.
Sleeves provide a protective barrier around the lamp so that the lamp can operate at its optimal temperature. For the quartz sleeve to maximize a unit`s performance, both the interior and exterior of the sleeve must be cleaned periodically, even in UV units installed in ultra-pure water systems. All quartz sleeves are susceptible to fouling.
Cleaning frequency of quartz sleeves will be site-specific and directly related to water quality. UV systems that are installed in post-reverse osmosis/deionization (RO/DI) locations will require cleaning much less frequently than units installed on raw water or surface water systems. As a general rule of thumb, a post-RO/DI system should have the quartz sleeves cleaned once a year.
Plan on cleaning quartz sleeves quarterly on post-activated carbon systems and more frequently for hard water applications exceeding 5 grains of hardness.
Standard clear quartz glass tube is high quality purity and automatic controlled fusing furnace
It has the characteristics of high purity,strong resistance,high transmission and accurate dimensions,and the OH content 1-20ppm after air of vacuum baking is available.
