Many customers and friends often consult customer service staff about the main uses of foam packaging machines. They don't know much about common sense in the field. Therefore, today's editors can use foaming machines and equipment.
1. Foamed plastic board is mainly used in construction sites, has the function of heat insulation and heat preservation, and is ambitious. So, in the southern part of the tropical climate, you can use air-conditioned rooms that are hot in summer to reduce energy consumption and keep you insulated. It is the most energy-efficient insulation material used in China's construction industry in the freezing regions of the north.
2. Packaging products: Shaped parts made of foam plastic box pads are now the best packaging materials, but in a sense, it has shockproof and shockproof effects. Foam plastic product packaging is mainly used for household appliances box mats, ceramic glass product packaging, tableware, outer box mats, food, health care box mats, wine, beverage box mats, raw vegetable preservation and seafood packaging, and pipe insulation. EPP foam box
3. Foam plastic floating material: Due to the low water absorption of foam plastic products, the surface has large buoyancy and is not easy to age. It has a certain mechanical strength, making it an excellent floating material and widely used in various containers. Lifesaving equipment, buoys, salvage, fishing and other surface operations.
4. Foam packaging products produced with foam packaging machines and other materials can be used to make May cement handicrafts, maybe animal specimens, movie props, promotional materials, stage set, product introduction, gallery exhibition, clip art ball models and other Manufacturing materials.
5. Castings disappear very quickly. The first is that foamed plastic products are composed of hydrocarbons, which will destroy the residual carbon powder at high and high temperatures. It has a certain mechanical strength, is easy to cut, simple to machine and glue.
6, the use of new filter material foaming small particles for small and medium-sized water supply and fresh water container water supply system, other researchers for seed germination and water layer breeding. Mixing clay, cement, fireproof materials, etc., can be made into lightweight wall insulation bricks.
2 new foam packaging technologies
Foam packaging has been widely used in foam packaging, epp auto parts packaging, construction, industry, sports and leisure, but the molding process of polypropylene foam is difficult. The main reason is the universal linear shape. The melt strength of polypropylene (LPP) is very low. The "feasibility" of the progressive foaming system, that is, how to improve the melt elasticity (melt strength), is the most important issue in the demand processing of polypropylene extrusion foaming.
Different from common methods such as "crosslinking, grafting and lowering temperature", we propose two new technical methods 33138 "melt mixing" and "melt insertion" for foam packaging and foam packaging. Used to improve the "melt strength" of polypropylene. The research work mainly involves the rheology and crystallization behavior of foaming systems, both of which have important effects on extrusion foaming. On this basis, the effects of raw material blending and molding processes on the extrusion foaming behavior of various polypropylene foaming systems were studied. After starting research work, new technologies for producing high-melting-point-strength polypropylene can be obtained, and the practical problem of high material costs in polypropylene extrusion foaming is currently being solved. Increasingly useful quality methods.
