Description
Technical Field
The invention relates to the field of design and manufacture of GMT felting mechanical equipment, in particular to a high-efficiency low-pollution GMT powder scattering device and a using method thereof.
Background
The light fiber reinforced thermoplastic composite material is abbreviated as GMT, and is mainly used as a structural part and an interior part in an automobile due to the characteristics of high specific strength, thermoplasticity, recyclability, easiness in processing and forming and the like. At present, with the expansion and extension of the market, the light GMT composite material is gradually developed into the fields of buildings, houses and the like.
Manufacturing lightweight GMTs internationally can be classified by process into dry and wet GMTs. The wet process technology is mainly monopolized by a few foreign enterprises represented by Hanhua and KPS, and is based on the traditional papermaking process and combined with special technical means, PP resin and chopped glass fibers are uniformly mixed and laid in a solution, and then the mixture is dried and hot-pressed to form the light GMT material. Because the lapping process is completed in the solution, theoretically, any additive can be added in the process, and the threshold of adding the additive by a wet method is reduced. The dry GMT method is characterized in that polypropylene fibers and glass fibers are uniformly carded together through a mechanical roller, a mixed fiber net (the gram weight is between 20g and 50 g) is laid, a single net is longitudinally laid into a plurality of layers of felt nets (between 10 and 100 layers) through a mechanical swing arm of a net laying machine, the felt nets are inserted and reinforced through a needle machine to form a 3D structure felt net, and the 3D structure felt net is baked and molded at high temperature through a thermal compound machine to form the high-strength light composite material. Because the dry mixing, carding, net forming, net laying and needling are all controlled by a precise machine: if the powder is added in the stages of mixing, carding and single-net, the powder spreading uniformity is ensured, but most electrical equipment can be seriously polluted, and the short circuit of the equipment can be caused by partial conductive powder; if the powder is added after lapping, the powder is accumulated on the upper layer of the felt net, the dispersibility of the powder is seriously influenced, and the effect of the auxiliary agent is greatly reduced.
At present, the domestic GMT production only adopts a dry process technology, so that the process is limited by the difficulty, and the addition of an auxiliary agent in the GMT is always a big problem, so that the traditional GMT can not meet the special requirements (flame retardance, low odor, antibiosis, far infrared and the like) provided by an automobile host factory more and more.
