As early as 100 years ago, people had to prepare polyacrylonitrile but no suitable solvent, failed to made fibers. Mimicking the performance of polyacrylonitrile fiber wool, good elasticity, elongation at 20% still maintain a 65% rebound rate, fluffy and curly and soft, warm and 15% higher than wool, synthetic wool said.

But you know what? Polyacrylonitrile fiber is not only a difference in the textile sector in recent years, have begun to emerge in the engineering field, Here we look at it together!

Polyacrylonitrile fiber reinforced material as a secondary concrete, "Sisiyuan" brand polyacrylonitrile fiber can significantly improve the toughness and impact resistance of concrete, and effectively prevent the emergence and development of cracks and improve the permeability of concrete durability, frost resistance, etc. Also as a reinforcing fiber asphalt concrete industrial product, it can not only greatly improve the adhesion of the asphalt pavement, high temperature stability, fatigue resistance, and low temperature cracking and prevent performance reflective cracking. Effectively improve the tensile, shear, compression and impact strength. It is a huge role and prospects for use in concrete engineering is increasingly being recognized and accepted.

"Sisiyuan" construction method polyacrylonitrile fiber brand:
◎ The role of the product in concrete is achieved through physical action, with concrete aggregate, admixtures, cement admixtures and do not have any conflict of mixing equipment and construction technology has no special requirements. Concrete construction method is as follows:
1, at the suggestion of adding volume and the amount of fiber each side mixed concrete and accurate weighing of fiber;
2, will be added to the prepared fiber sand, stone, cement compound, be added to the mixer; the first dry mix for 30 seconds, 1 minute plus wet mix can be put into use.
3, after adding fiber construction process and maintenance process and not added fiber concrete concrete identical.

Note: After adding fiber, reinforced concrete cohesiveness, slump down slightly, it is recommended to change the amount of admixture, not by increasing the amount of water can be adjusted.
