The above seeds were wrapped in a sandcloth, squeezed out a portion of the water, and placed in a refrigerator at a temperature of about 5°C. Rinse the seeds one at a time with water every morning and evening. After 2 days, dry the seeds in a bright environment. Rinse with cold water twice a day. After each flush, use an electric fan to blow the seeds for 5-10 minutes to blow off excess water from the seeds so as to avoid causing oxygen deficiency and affecting germination. Generally after 5-6 days to germinate.
2, cool treatment: The seeds that have been soaked in the first method are wrapped in gauze and squeezed and wrapped. Then hang it in the deep well, 40-50 centimeters from the surface of the water, and remove it twice a day with clean water. After washing, the surface of the seed should be dried with a fan and then wrapped in a well. This can be germinated and sown after 6-8 days of treatment.
Automatic Fitting Fabrication Of Plastics
Fabricated fittings are constructed by joining sections of pipe,machined blocks, or molded fittings together to produce the desired configuration.
Components can be joined by butt or socket heat fusion, electrofusion, hot gas welding or extrusion welding techniques. It is not recommended to use either hot gas or extrusion welding for pressure service fittings since the resultant joint strength is significantly less than that of the other heat fusion joining methods.
Fabrication of Plastics designed for full pressure service are joined by heat fusion. For Hdpe/poly/polyethylene Fitting Fabrication of Plastics, Yuda RGH workshop plastic pipe fitting welders can make elbow, tee, cross and wye fittings in relevant clamps. For eliminating operator errors and increasing productivity, you can choose RGH-A series CNC Polyethylene Fabrication Machines, or Fully automatic HDPE Fusion Fittings Welder with all jaws operated hydraulically for faster welds, precision welding operation, and data logger function.
