電子防垢、除垢

Electronic scale prevention and removal

原理是：利用高頻電場改變水的分子結構，使其防垢和除垢。當水通過高頻電場時，其分子物理結構發(fā)生了變化，原來的締合鏈狀大分wyt_dsry子，斷裂成單個水分子，水中鹽類的正負離子被單個水分子包圍，運動速度降低，有效碰撞次數減少，靜電引力下降，無法在受熱壁式管面上結構，從而達到防垢目的。同時由于水分子偶極矩增大，使其與鹽的正負離子（水垢分子吸合能力增大，使受熱面或管壁上的水垢變得松軟，容易脫落，產生了除垢的效果。

The principle is to use high-frequency electric field to change the molecular structure of water to prevent and remove scale. When water passes through the high-frequency electric field, its molecular physics structure changes, and the original associated chain like large component wyt_ The dsryon breaks into a single water molecule, and the positive and negative ions of the salt in the water are surrounded by a single water molecule, resulting in a decrease in movement speed, effective collision times, and electrostatic attraction. It is unable to structure on the heated wall tube surface, thus achieving the goal of scale prevention. At the same time, due to the increase in the dipole moment of water molecules, the adsorption ability of water molecules with positive and negative ions of salt (scale molecules) increases, making the scale on the heating surface or pipe wall soft and easy to fall off, resulting in a descaling effect.

靜電防垢、除垢與電子除垢一樣，也是通過改變水分子狀態(tài)來實現防垢、除垢目的的。只不過后者是利用靜電場的作用，而不是電子作用。其機理是水分子具有極性（也稱偶極子），當水偶極子通過靜電場時，每個水偶極子將按正負有序地連續(xù)排列。如水中含有溶解的鹽類，其正負離子將被水偶極子包圍，也按正負順序排列于水偶極子群中，不能自己的運動，因而也就不能靠近管（器）壁，并進而沉積于管（器）壁上形成水垢。同時，水中釋放的氧，可使管壁產生一層極薄的氧化層，可以防止管（器）壁腐蝕。

Electrostatic scale prevention and removal, like electronic scale removal, also achieve the purpose of scale prevention and removal by changing the state of water molecules. However, the latter utilizes the action of an electrostatic field rather than the action of electrons. The mechanism is that water molecules have polarity (also known as dipoles), and when water dipoles pass through an electrostatic field, each water dipole will be continuously arranged in a positive and negative order. If the water contains dissolved salts, its positive and negative ions will be surrounded by water dipoles and arranged in a positive and negative order within the water dipole group. They cannot move on their own and therefore cannot approach the wall of the tube (vessel), which in turn deposits on the wall to form scale. At the same time, the oxygen released in water can create an extremely thin oxide layer on the pipe wall, which can prevent corrosion of the pipe (device) wall.
