回转式格栅清污机厂家 只不过后者是利用静电场的作用，而不是电子作用。其机理是水分子具有极性（也称偶极子），当水偶极子通过静电场时，每个水偶极子将按正负有序地连续排列。如水中含有溶解的盐类，其正负离子将被水偶极子包围，也按正负顺序排列于水偶极子群中，不能自己的运动，因而也就不能靠近管（器）壁，并进而沉积于管（器）壁上形成水垢。同时，水中释放的氧，可使管壁产生一层极薄的氧化层，可以防止管（器）壁腐蚀。化学法利用化学剂使表面污染或覆盖层与其发生化学反应而被除去，如对垢层的酸洗、碱洗等。为使基材在化学清洗中不受腐蚀或使腐蚀率控制在允许范围内，通常在化学清洗液中要加入适量的缓蚀剂和起活化、渗透、润湿作用的添加剂。
The manufacturer of rotary grille cleaner only uses electrostatic field instead of electronics. The mechanism is that water molecules have polarity (also known as dipoles), when water dipoles pass through the electrostatic field, each water dipole will be in a sequence of positive and negative. If there are dissolved salts in water, the positive and negative ions will be surrounded by water dipoles and arranged in the order of positive and negative in the water dipole group, so they can not move themselves, so they can not be close to the wall of the tube, and then deposited on the wall of the tube to form scale. At the same time, the oxygen released from the water can make the pipe wall produce a very thin oxide layer, which can prevent the corrosion of the pipe wall. Chemical methods use chemicals to cause surface contamination or chemical reactions with the coating to be removed, such as pickling and alkaline washing of the scale layer. In order to prevent the substrate from being corroded in chemical cleaning or to control the corrosion rate within the allowable range, an appropriate amount of corrosion inhibitor and additives with the functions of activation, permeation and wetting should be added to the chemical cleaning solution.
