Production of parts from polymer composite materials (PCM)

Workshops for manufacturing parts from polymeric materials consist of sections:

Binder preparation

Making prepregs,

Winding and laying out,

Snap preparation,

Forming and curing the resulting workpieces,

Preparation of parts for autoclave molding,

Autoclave and pressing,

Machining.,

The main methods of manufacturing parts from PCM are laying and winding prepregs on the finished form.

The main hazardous substances are: vapors of various organic compounds and dust from processed materials.

Emissions of harmful substances from the main processes in g / hour are given in table.

Production of parts from polymer composite materials (PCM)

  1. Polymeric materials for shoes
    Currently, about 70% of shoes are made using polymer materials. The main raw materials in the production of artificial materials for the top, bottom and inner parts of shoes are rubbers, latexes, plastics, synthetic resins, film-forming and binders, solvents, dyes, synthetic and artificial fibers and fabrics, as well as various additives
  2. Polymer materials intended for contact with food
    Hygienic requirements for products made of polymeric materials. For polymeric materials in contact with food, along with such requirements as strength, economy, manufacturability, consumer acceptability, decorativeness, the possibility of disposal, etc., certain hygienic requirements are imposed. These requirements are set out in the “Instruction for sanitary-chemical
  3. Sealing areas for electronic equipment with polymer materials
    When sealing products of electronic equipment (CEA), various polymeric materials are used: compounds, adhesives, varnishes, enamels, sealants, etc. Technological processes for sealing REA products include the following operations: surface preparation, degreasing, applying, pouring or impregnating, drying. Major hazardous substances: fumes of various organic
  4. Production of parts by powder metallurgy
    In the manufacture of parts based on iron and copper powders, the following gases are released into the atmosphere: di-iron trioxide, copper oxide, zinc octadecanoate, ethanol, gasoline, carbon oxide, tetrachlorethylene. Calculations of emissions of harmful substances should be carried out according to the formula (5). The specific emissions of harmful substances into the atmosphere from the main types of equipment for the production of parts by powder metallurgy are given in
  5. Sanitary control over the production and use of materials intended for contact with food
    At the food industry enterprises of the corresponding branches of agriculture, public catering and trade systems, various products (utensils, containers, packaging, equipment, implements, consumer goods, etc.) are used in everyday life, made of various materials: metals and alloys, porcelain, faience, glass and a relatively new type of materials (see, below) - polymer.
  6. RMB
    RMB - The Habitual Picture of the World - is the sum of impressions and beliefs with which we perceive the world. Most often, these are facts that you have not verified: you just took someone’s word for it or someone’s authority convinced you. Mom said - in the land of germs. Dad said - from food - power. The teacher said - There is no magic. Please note that they didn’t come up with this themselves - someone also told them about it. AND
  7. About RMB and VKM
    Often you will see the abbreviation PKM on the pages of the book. That is a HUGE PICTURE OF THE WORLD. This term is used in many philosophical, psychological, esoteric schools. RMB (Habitual Picture of the World) is the sum of impressions and beliefs with which we perceive the world. Most often these are unverified facts, you just took someone’s word for it or someone’s authority convinced you. Mother

  9. Mechanical surface preparation of parts
    To remove molding, core mixture and scale from casting surfaces, shot blasting and shot blasting, tumbling are used. The main harmful substance released into the atmosphere is inorganic dust. Calculations of emissions of harmful substances should be made according to the formulas (4.5). Specific emissions of harmful substances into the atmosphere from the main types of equipment during mechanical
  10. About RMB
    Often you will find such an abbreviation on the pages of a book - RMB. That is a HUGE PICTURE OF THE WORLD. This term is used in many philosophical, psychological, esoteric schools. In my opinion, the easiest way to explain this is from the position Map - Territory. There is our Earth - Territory - a huge geobioenergy-information complex that lives by its own laws and regulations. Each of
  11. I draw RMB
    RMB - A familiar picture of the World. And in my imagination, such a picture immediately arises: a boundless field, soft earth, silk green grass. People are moving across the field in all directions. They crush grass, trample the earth. The most found trails deepen, become a rut. Many paths are so beaten by generations that people are hidden in them with their heads and do not see from there the entire surface of the earth.
