导热灌封胶沉降怎们办?

导热灌封胶沉降怎们办?

导热灌封胶发生沉降是一种非常正常的现象,往里面加导热粉后,基材是硅油,导热粉的密度高于硅油,油重粉轻,就容易发生沉降,而且导热系数越高,沉降的越快,所以高导热系数的灌封胶是否好用,就看多长时间开始发生沉降和沉降后能否再次……

导热垫片的自粘性是涂胶才有的吗,多久时间消失?

导热垫片的自粘性是涂胶才有的吗,多久时间消失?

导热垫片自带粘性是材料本身特性,原始设计当中就具备此特点,不是通过涂胶来实现的,不会对材料导热性能产生影响。在储存期内,自粘性不会消失,但会随着产品老化而消失。自粘型的好处是为了方便操作,与导热绝缘片系列产品相比,表面带……

导热垫片能直接锁螺丝吗?

导热垫片能直接锁螺丝吗?

这个问题为了快速作业,在使用中经常碰到,答案是否定的,很抱歉!虽然导热垫片的源头是硅橡胶,但不是工程塑料,机械强度非常差,由于导热垫片比较软,不能直接开孔锁螺丝固定,这样会使导热垫片开裂碎掉,所以建议不要投机取巧,但是可……

AB管快干胶混合后开始固化时为何有点烫手

AB管快干胶混合后开始固化时为何有点烫手

您用的这个快干胶应该是环氧树脂体系的AB快干胶,环氧树脂胶固化时会放热,有大量的热量往外散,所以用手触碰就是烫手的感觉。快干胶的固化速度非常快,意味着热量会迅速爆发出,与固化慢的环氧胶相比,会更烫手。还有,释放的热量跟混……
