New Building Formwork

In today's era of rapid progress and development of various things, the construction industry has become a pillar industry in my country, and building formwork is an important tool for the construction of concrete structure projects. In the current engineering construction, the formwork engineering accounts for 20%-30% of the cost of the concrete project. %, accounting for 30%-40% of the engineering labor, accounting for about 50% of the construction period. Therefore, formwork technology directly affects the quality, cost and benefit of engineering construction, which makes the requirements of various projects in the construction industry gradually higher for building formwork.

Ⅰ. Types of building shuttering

At present, the available building formwork mainly includes aluminum formwork, wood formwork, plastic formwork, etc., but there are still some fly in the ointment:

1. Wooden formwork.

It has high cost of use, is not resistant to corrosion, wear resistance, poor waterproofness and cannot be recycled, which is contrary to the concept of energy saving, environmental protection and green building advocated by the state.

2. PVC building formwork.

The use cost is low, but the weight is large, which is not conducive to handling, and is only suitable for large-scale projects.

The above problems have forced people to develop lighter and more durable building shuttering. After repeated tests and careful research and development, Yunnan Jingchun Trading has produced a new type of plastic formwork - a new type of hollow plastic formwork.

The new hollow plastic template is based on imported polypropylene resin, adopts an exclusive formula, and adds chemical additives such as toughening, strengthening, weather resistance, anti-aging, and flame retardant. It has high strength and small deformation, and is suitable for use in various conditions.

The hollow plastic building formwork modifies the conventional PP material by applying the polymer nanotechnology, and creates the "nano polymer additive". For the disadvantages of building formwork, the deformation rate of the formwork is perfectly controlled within 2mm, and the diagonal line is controlled within 0.5mm, which better meets the construction needs.

Ⅱ. The performance comparison between plastic building formwork and various forms is as follows:

The superiority in performance makes the building formwork have the incomparable advantages of traditional formwork: its surface is a polymer material, smooth and clean, the formwork splicing is tight and smooth, the demoulding is easy, and no release agent is required, which saves cost and time for construction. And the density of plastic formwork is only 1/21 of that of steel, light weight, convenient for workers to carry, saving time. The formwork will not deform and absorb water during use, which can greatly improve the construction safety.

If the formwork is damaged, it can be recycled and regenerated 100%, reducing the impact of waste on the environment, and it has the convenience of use of conventional building formwork and more features than conventional formwork.

The needs of the society have prompted the continuous innovation and development of building formwork. At the same time, the new plastic formwork will also push the construction industry to a new climax.
