The surface of traditional formwork is directly impregnated with wood bark or melamine, which is not waterproof and peels when it touches concrete. The concrete structure is very rough, and it is difficult to demould, which is very destructive to the formwork. Green building formwork is wrapped with polymer fiber skin, which has the characteristics of high strength, high temperature resistance, wear resistance, acid and alkali resistance, no water seepage and no adhesion with concrete. Easy demoulding and smooth concrete structure. It has been proved that the water purification effect has been completely achieved.
The traditional formwork adopts horizontal technology, and the core of the formwork is made of nine layers of wood bark bonded by glue. Due to the influence of raw material moisture, glue quality, glue uniformity, manual board laying technology, hot pressing temperature and pressure and many other factors, the product has some shortcomings, such as easy foaming and bursting, easy delamination, uneven thickness, poor strength, distortion and rough surface. The green building formwork adopts the slab core structure with vertical structure and no delamination, with extremely uniform thickness and high strength, and the overall structure does not delaminate.
Due to process problems, the traditional formwork can only produce two specifications: 1830×9 15 and 1220×2440, and must be cut after arriving at the site, which wastes materials, manpower and time. Green building templates can be customized, positioned and standardized according to the engineering structure, saving a lot of materials, time and manpower.
Due to material problems, traditional templates can only be turned around for 5-8 times; The performance of green building formwork is improved, so the utilization rate is improved, which can be 60-80 times.
I hope my answer is helpful to you!
