1、Strong combination between coating and matrix ensuring long service life of coating without any peeling.
2、With higher hardness of coating,abrasion resistance will increase manyfold and service life will be prolonged linearly.
3、Thickness of coating could be even and accurately controlled, ensuring precision of rolls.
4、Surface roughness ofcoating will reach to Ra0.4~0.6 after special fine polishing, pretty suitable for high-speed corrugated cardboard making machine.
5、Matching with flute designs of UVand UVV type, increase efficiently hardness of cardboard and deduct wastage of paste and medium paper.
6、Theoretically, flutes in service will be never worn and take up ratio will be never changed.
7.By using tungsten carbide corrugating rolls, cardboard will be maintained atcertain thickness and printed always flat for stable quality of cardboard and carton.
8、Used coating could be removed by special process and the rolls could be refurbished for reuse.
9、Improvement in service life deducts frequencies of changing, saving expenditure of manpower and material resources.
