Processing method for renewable waste plastic glass fiber building formwork

Abstract

The invention discloses a processing method for a renewable waste plastic glass fiber building formwork. The processing method is characterized by comprising the following steps of: firstly, sorting materials and manually sorting, cleaning and drying different materials; secondly, crushing and drying the sorted materials; thirdly, mixing and blending the crushed materials; fourthly, mixing and granulating; fifthly, conveying the granulated materials to an extruding machine hopper; sixthly, heating and melting; seventhly, casting; eighthly, carrying out compression moulding forming; ninthly, cooling and setting; and tenthly, shearing. The processing method has the advantages of favorable strength, small deformation, high turnout frequency, favorable demoulding effect, 100 percent of recovery of waste plates, environment friendliness and energy saving.

Description

technical field [0001] The invention relates to building templates, in particular to a processing method for renewable waste plastic glass fiber building templates. Background technique [0002] In the construction of houses, bridges, tunnels and brick production, the concrete pouring process is often applied, and the concrete pouring process requires formwork. Traditional formwork includes wood boards and steel plates. Due to the shortage of wood board resources and the weight of steel plates, synthetic building formwork is gradually used. Among them, wood-plastic building formwork is commonly used. Wood-plastic building formwork is made of waste plastics PP, ABS , PVC, PE and other recycled particles, which are mixed with wood powder or plant stem powder as filler (black), its disadvantages are: it will be deformed when heated in the sun; nails will crack when they are nailed below zero; when dropped at high altitude It is easy to break when it falls; it cannot be constru...

Problems solved by technology

Traditional formwork includes wood boards and steel plates. Due to the shortage of wood board resources and the weight of steel plates, synthetic building formwork is gradually used. Among them, wood-plastic building formwork is commonly used. Wood-plastic building formwork is made of waste plastics PP, ABS , PVC, PE and other recycled particles, which are mixed with wood powder or plant stem powder as filler (black), its disadvantages are: it will be deformed when heated in the sun; nails will crack when they are nailed below zero; when dropped at high altitude It is easy to break when it falls; it cannot be constructed in winter; the other is stone powder plastic building formwork

Stone powder plastic building formwork is composed of recycled particles such as waste plastics PP, ABS, PVC, PE, etc. The filling inside is stone powder. The disadvantages of this board also exist: heat deformation under the sun; Cracking; construction is not possible in winter, and the biggest disadvantage is poor thermal stability, high temperature, wavy shape, and low turnover times

Moreover, the above two synthetic building formworks still have small specifications and sizes, inconvenient mold assembly, large loss, easy sticking of concrete on the surface, need to brush release agent, and troublesome demoulding; delamination phenomenon will appear in the formwork when it encounters water

It can only be assembled with small pieces, which is time-consuming and labor-intensive; waste formwork has no value in use and cannot be recycled
