Fascia gun, also known as deep myofascial impactor, is a soft tissue rehabilitation tool that relaxes the body's soft tissue through high-frequency impact. Fascia gun can be understood as a civilian version of DMS (electric deep muscle stimulator). Its vibration frequency will change when it is used, and its basic function is similar to that of DMS. The use of the fascia gun must pay attention to the way and method. At the same time, the first use of the fascia gun should be under the guidance of professionals. It is best to use it step by step, otherwise it may cause damage.
The large round head of fascia gun is generally used for shoulder, back, hip and thigh; The small round head is used for large areas of muscles such as arms and legs. The fascia gun should be used along the muscle texture and fascia direction of the human body, not just against the muscle sores. However, a large number of nerves and blood vessels such as the head, cervical vertebra and spine cannot be used. The recommended length of use for each part is 3 to 5 minutes. The correct use of fascia gun will not lead to muscle swelling. Therefore, if this happens, it means that the muscle is damaged due to improper use. The joints, groin, armpit and other areas with rich nerves and blood vessels and no muscle protection should be avoided.
The fascia gun transmits the force and vibration to the fascia of the human body through high-frequency vibration (2000-3200 times/min), so as to increase the tissue blood flow and relax the muscles. It can also make the human tissues produce relative displacement through resonance, reduce tissue adhesion, restore the elasticity of muscles and fascia, relax the tense and stiff fascia, and relieve some discomfort symptoms of the human body.
At present, the existing methods for disposing of waste plastics at home and abroad are only for regeneration, landfill and incineration. These treatment methods will cause re-contamination to varying degrees. How can we dispose of used plastics thoroughly, safely, economically and without pollution?
Plastics are based on a variety of polymeric hydrocarbon polymer molecules as the main component. The raw materials in plastics are: various hydrocarbon polymer molecular polymers and various additives. How many different resins and additives affect the performance of plastic products, there are more than 100 types of plastics, plastics can be divided into two types according to their properties:
(1) Thermoplastics such as polyethylene, polypropylene, polystyrene, polyvinyl chloride, nylon, ABS, etc. (2) Thermosetting plastics such as phenolic, epoxy, and unsaturated polyesters. Commonly used in everyday life are waste plastic film, packaging tape, woven bags, fast food boxes, foam plastics, plastic food bags, scraps of plastic products, and a variety of electrical enclosures. All plastics are formed by the polymerization of C and H in crude oil. The polymer compound.
The chemical composition of petroleum (crude oil) has two major categories: one is hydrocarbon, which means that it contains only two elements of C and H, and the other is non-hydrocarbon, which means O, S, N and other heteroatoms. Hydrocarbons composed of petrochemicals, that is, polymer compounds formed by the polymerization of two elements, C and H, are the main components of plastics. It can be seen that plastic products actually originate from petroleum.
The principle of catalytic cracking of waste fuel under normal pressure at atmospheric pressure is to cut large macromolecule chains at a certain temperature through nanotechnology to form small molecular chain hydrocarbons, and the small molecular chain compounds are generally around C4 to C20. It is a component of steam, coal and diesel oil. Wax oil and heavy oil no longer exist in this catalytic cracking process.
The main process flow Waste plastics → pretreatment → automatic feed → melt decomposition → catalytic cracking → cooling → crude oil → fractions → condensation → refining and refining → finished products.
