According to the different use characteristics of famous plastics, the production of food plastic products in Quzhou City is usually divided into three types: general plastics, engineering plastics and special plastics. First, general-purpose plastics generally refer to plastics with large production capacity, good formability, cheap price and wide use. The reason of shrinking pit is the same as insufficient filling, which can be solved by excess filling in principle, but there will be stress. Attention should be paid to uniform wall thickness in design, and the wall thickness of reinforced ribs and convex columns should be reduced as much as possible. The treatment of the overflow edge should mainly focus on the improvement of the die. On the other hand, in the forming conditions, we can start to reduce the liquidity. The representative parts on the car are dashboard, rearview mirror, bumper, seat cushion, headrest, steering wheel, instrument panel anti-vibration pad, pillar decoration, front roof lining, window frame, ceiling and side roof frame decoration, door liner, sunshade board, rear roof frame decoration and so on.
It is necessary to strengthen the temperature control during the autumn breeding season of Chinese bees, although the bees have a certain ability to regulate the temperature in the hive, but it is more conducive to the autumn reproduction of the beehive if it can provide a suitable temperature, such as appropriately expanding the hive door or building a sunshade on the beehive when the temperature is generally high in the early stage, while strengthening the heat preservation of the hive when the temperature is generally low in the later stage, such as properly reducing the hive door or covering the hive with insulation.
The importance of glass greenhouse. Temperature is the basic condition to ensure the normal growth of crops. Greenhouse is a thermal insulation agricultural facility for the normal and rapid growth of crops. Heat preservation is an important work in greenhouse agricultural production, so suitable covering materials must be selected. Generally speaking, glass greenhouse is better than glass greenhouse, glass greenhouse can play a decorative role in appearance, and the aging and damage problems of glass greenhouse can be relatively small compared with plastic greenhouse; in terms of performance, due to the complexity of the environment, glass greenhouse can resist various loads (wind load, snow load, etc.). Aluminum alloy (or stainless steel) + plexiglass, ordinary glass, low-cost bamboo ponds and plastic films with beautiful and durable, windproof, rainproof, sunscreen, heat preservation effect and cost, can also be equipped with sunshade and sprinkler system. Plants usually need plenty of light and better glass. Of course, the one-time investment cost of plastics is lower, but the later maintenance cost is also higher, and plastics are easy to age.
Spray-free plastics are more and more used in home appliances and automobiles because of their excellent appearance, environmental protection and economy. In the field of household appliances, non-spraying materials are used in soymilk machines, drinking fountains, electric cookers, water heaters, washing machines, refrigerators, air conditioners, televisions and so on. In the automotive field, spray-free materials can be used for DVD face frames, central control panels, side skirts, glove boxes, sunshades, instrument panels, etc.
Foshan Chenghang plastic Technology Co., Ltd. for you a detailed interpretation of UOJWGl Jieyang City pc Sunshine wavy tile manufacturers spot related knowledge and details, sunlight board set lighting, heat preservation, sound insulation in one, sunshade and rain, can also be used for greenhouse, furniture canopy, office sound insulation, outdoor advertising light box and so on. In foreign countries, in addition to supporting the structure, the pure polycarbonate material quantity of large-scale bright lighting house, a sunshine, crystal transparent, warm and annoying.
