PP composite material is a material composed of GF and PP resin. Due to the different types of GF and PP types and structural status, the mixing method is very different from the mixed category. : Dry method and wet process. This article mainly introduces the dried method, which is no longer described in the wet process.
The dry method is generally called a combing process, which is based on the development of non -woven machinery technology. The specific production method is mainly divided into two parts: the felt part and the board part.
Miss -making parts mainly include: fiber opening, pine, mixing, combing, net, acupuncture and scrolls.
The plate parts mainly include: surface treatment of felt materials, decoration and selection of non -woven fabrics, heating melting plate pressure or roller pressure and cutting edges.
The main steps of the traditional foundation part are as follows:
01
Open the bag. The fiber purchased on the market is generally bags and compressed. It needs to be opened by a charter to make most of the block or ductive fibers decompose and discrete into flocculent or bundle. Then transport it to the next process.
Features of the charter: The electronic automatic pound cotton device is installed in the charter, which can mix different fibers according to the proportion of the product.
02
Kaisong. The fiber after the opening package only removes the compression of the bag. The fiber is still small in a small piece. It needs to pass the pine process to disperse the fiber to a certain extent, and then transport it to the next process. The pine machine is equipped with a rake thorns roller, which can achieve the purpose of the chemical fiber after the package to the initial pine, that is, from a large fiber block, fiber group, or fiber bundle to a smaller fiber block or fiber bundle.
The principle of Kaisong: According to the decentralization requirements of the felt material, Kaisong can generally be divided into pre -kaison and essence. The pre -pine is generally used in the blade type (the blade installed on the pine tin forest). Pine pine is generally used to open pine with a combing needle nail plate (with a combed needle on the pine tin forest).
03
Okura is mixed with cotton. The important process of Masaki Mixed Cotton is compared to some of the fiber -mixed fibrous fiber felt, which is mainly to complete the functions of mixing, pine, reserves of various fiber raw materials. At the same time as damage, the mixed fiber must be uniformly flocked and the fiber raw material is transported and fed evenly. The equipment is a cotton box.
