Description
Technical field
The present invention relates to construction formwork, particularly relate to the processing method of renewable waste plastics glass construction formwork.
Background technology
In the constructions such as house building, bridge, tunnel construction and fragment of brick production, often application pouring concrete technique, concrete placement needs template.Conventional template comprises plank and steel plate, due to plank resource scarcity, steel plate is too heavy again, now use synthesis construction formwork gradually instead, what described synthesis construction formwork was wherein commonly used has wood plastic building mould, wood plastic building mould is made up of regenerated particle such as waste plastics PP, ABS, PVC, PE, and the inside is mixed with wood powder or plant rod powder is that inserts produces (black), and its shortcoming is: be heated under the sun and can be out of shape; Subzero nail one nail can ftracture; Easily break when high-altitude is dropped; Winter can not construct; Another kind is stone flour plastic building template.Stone flour plastic building template is made up of regenerated particle such as waste plastics PP, ABS, PVC, PE, and the inside filler is stone flour, and the shortcoming of this plate also exists temperature distortion under the sun equally; Subzero nail one nail can ftracture; High-altitude is dropped and is easily broken; Winter can not construct, and also have maximum drawback to be that heat stability is bad, temperature is too high, occurs wave-like, and the number of turnover is few.And it is few that above-mentioned two kinds of synthesis construction formworks also also exist specification, and spell mould inconvenience, loss is large, and surface is sticky concrete easily, needs brush release agent, demoulding trouble; Meet water template and there will be stratification.Can only be assembled with fritter, time-consumingly to take a lot of work; Useless template is without value, not recyclable.
Summary of the invention
The object of the invention is the shortcoming existed to overcome prior art, there is provided a kind of with recycled plastic, be primary raw material in conjunction with glass fiber, shaping template reaches minus 20 degrees and also can construct, and high-altitude is dropped and do not broken, and nails winter and does not ftracture, under the sun, temperature distortion is little, the number of turnover is up to more than 50 times, and stripping result is good, and useless plate 100% reclaims the processing method of the renewable waste plastics glass construction formwork of environmental protection and energy saving.
