Problems solved by technology

Moreover, the transportation cost of ordinary plastic pallets accounts for a high proportion of the product price. The domestic shipping fee is 10 to 15 yuan / piece, accounting for about 5% of the product price, and the export transportation fee is 50 to 80 yuan / piece, accounting for 25 to 40% of the product price. , because the transportation cost of export is particularly high, it is difficult to sell domestic plastic pallet products to the international market

Embodiment Construction

[0024] Below in conjunction with embodiment the present invention is described in further detail.

[0025] The production process of super-strong glass fiber plastic trays, the materials used in super-strong glass fiber plastic trays are super-strong GFR-PP rods and super-strong GFR-PP plates, and its production includes super-strong GFR-PP Plate welding forming production process; the forming process adopts continuous forming or local heating during plate making, mold forming or general mechanical method; ultrasonic welding is used, or ordinary heating is used to melt and then extrude.

[0026] The production process of super-strength glass fiber rods is that the glass fibers are placed at the head of the plastic extruder at the front of the screw, extruded together with the polypropylene resin melt, and each strand of glass fiber adhered to the polypropylene resin is pulled Out of the machine head, after cooling, it becomes a super-strength fiberglass wire; the super-strengt...

Abstract

The present invention discloses production process of super strong GRP tray, and the super strong GRP tray is made with super strong GRP rod and super strong GRP plate and through ultrasonic, heating or pressurized welding. The super strong GRP tray may be made with only super strong GRP plate and the corresponding production process includes the steps of cutting material, forming, combining, welding or adhering. Or, super strong GRP tray may be made with super strong GRP plate and super strong GRP to form skeleton, and the corresponding production process includes the steps of cutting material, forming plate, locating the facing sheet, pressurizing the rods, welding, etc. The super strong GRP tray product has the advantages of high mechanical performance, powerful bearing capacity and low cost.

Description

technical field [0001] The invention relates to a production process of a super-strong glass fiber plastic tray. Its products have the characteristics of super strong mechanical properties and bearing capacity, and low processing cost. Its cost performance is much better than conventional plastic pallets, and can be widely used in construction, transportation and civil life and other fields. Background technique [0002] Among the five general-purpose plastics of polymers, polypropylene (PP) is the fastest-growing variety. PP modification, like PE, can be divided into two methods: chemical modification and physical modification. Chemical modification is mainly copolymerization, grafting, crosslinking, etc., and the purpose of modification is achieved by changing the molecular structure of polypropylene (PP). Physical modification is mainly to add additives such as blending, reinforcement, filling, etc. to endow polypropylene (PP) with new properties. The purpose of modify...
