| 1、在混凝土结构上固定尼龙衬板技术 在混凝土结构的贮槽、料斗等安装时，尤其是对旧的贮槽或料斗，应校核混凝土结构强度（水泥层的厚度和牢固性是很必要的），混凝土的厚度和结构对安装尼龙衬板的牢固性有着直接的关系。 按照校核结果，选择适当的紧固材料。一般用专用膨胀性螺栓联接，膨胀螺栓必须安在无裂缝、无孔洞的坚硬水泥层上（在上述情况不具备的情况下采用塑材铰钉，也能保证把衬里牢牢固定住）。固定螺栓之间的距离依赖于尼龙衬板的厚度和操作条件而定。 2、在钢结构上固定尼龙衬板技术 固定尼龙衬板一般采用：（1）钢板转钻孔法（2）焊接螺栓法 由于尼龙衬板的膨胀系数是2×10-4/℃，在操作或环境温度出现较大变化的情况下，尼龙衬板的固定形式必须考虑它自由膨胀或收缩。 1, in the concrete structure fixed on nylon lining technology in the concrete structure of the storage tank, hopper installation, especially for tank hopper or old, should check for structural strength of concrete (cement layer thickness and consistency is necessary), the firmness of the thickness and structure of concrete to install nylon lining the board has a direct relationship. According to the check result, choose the proper fastening material. General use special expansion bolts, expansion bolts must be installed in no cracks, no holes in hard cement layer (not available in the case of the plastic hinge pin, can also ensure that the liner is firmly fixed). The distance between the bolts depends on the thickness of the nylon lining and the operating conditions. In 2, the steel structure is fixed on nylon lining plate fixed nylon lining by: (1) plate rotating drilling method (2) by the method of welding bolt nylon liner expansion coefficient is 2 * 10-4/ DEG C, the larger changes in the operation or ambient temperature under the condition of fixed type nylon lining plate must be it is free to consider expansion or contraction. |
