                                      铁瓶盖在封盖时旋得越紧越好吗?

                                          铁瓶盖简单机械,是斜面的变形。圆柱体表面有像螺蛳壳上的螺纹叫做阳螺旋,在物体孔眼里的螺纹叫做阴螺旋。阴阳两组螺旋配合起来,旋转其中一个就可以使两者沿螺旋移动,螺纹愈密,螺旋直径愈大愈省力。

                                      1.加强桶/板桶的坚固度

                                      2 铁盖让全?#26696;?#21152;美工,大方,漂亮

                                      3 捅底有凹型,铁盖可以让桶与桶上下对放更加稳固,平稳,同时底部跟地面有一定的空间距离,可以防止桶潮湿和运输中的磨损

                                      封盖时旋得越紧越好吗?     

                                      大多数玻璃瓶装罐头的密封,主要是由瓶内真空度决定的,而非依靠爪与螺纹的扣合,爪的作用?#37995;?#20445;证杀菌过程中盖与螺纹的扣合,以及重复封盖,杀菌冷却后的密封主要依靠瓶内的真空来保证。通常标准瓶盖与标准玻璃瓶(符合DIN6094)配合,封盖时盖爪进入瓶口螺纹线的1/3-1/2处即为较理想的配合。
                                        过度封盖反而易造成爪变形,爪生锈,慢性漏气,杀菌跳盖等?#22909;?#24433;响。因此,铁瓶盖在封盖时应注意适当的封盖扭力。
