Gasification materials of powder is overmuch, material layer resistance increases, permeability worse.
气化原料中粉末过多，料层阻力增大，透气性变坏。
This structure forms the passivation layer against corrosion and wear. The optimum layer against wear improves the resistance of material surface in corrosion, wear and fatigue extremely.
这种结构形成了抗磨损的优化表面层和抗腐蚀的钝化层，明显改善了材料表面抗磨损、抗疲劳和抗腐蚀特性。
This instrument is an internation of single and multi-layer and cardboard corrugated cardboard, also can be used for silk, cotton, etc of non-paper-made material strength of resistance test.
式仪器，广泛地适用于包装材料，主要用于测定各种纸板及单层和多层瓦楞纸板，也可用于丝绸、棉布等非纸质材料的耐破强度的测试。
