前言去除绘画上附着的泥土、尘埃、颜料、墨迹等,用以往的方法,效果都不太理想,而且容易对绘画造成损伤。本实验是用空吸网和超声波发生器配合,对上有胶矾的绢上的墨迹,进行局部清洗,效果颇佳。透过具有一定面积与厚度的过滤材料,利用真空泵制造强制气流,则从该材料上部滴下的液体,被通过液体周围的气流阻碍,不能沿着与材料平面相平行的方向扩散,而是大致垂直地,顺着厚度方向被直接排出。根据这种现象做成的装置,就是空吸网。因为可以把纸、布等作为过滤材料,所以,对纸质或绢质的书画,可以采用这种方法进行局部清 Preface Removal of dirt, paint, ink and the like adhering to the painting can not be achieved by the conventional methods, and can easily cause damage to the painting. This experiment is the use of suction net and ultrasonic generator with a glass on the alum silk ink, local cleaning, the effect is quite good. By using a filter material of a certain area and thickness to create a forced air flow by means of a vacuum pump, the liquid dripping from the upper part of the material is obstructed by the gas flow around the liquid and can not diffuse in a direction parallel to the plane of the material, but is substantially vertical Ground, along the thickness direction is directly discharged. According to this phenomenon made of the device is empty net. Because you can put paper, cloth, etc. as a filter material, so paper or silk painting, you can use this method for local clear
