    环氧地坪漆涂料施工高压无气喷涂

    在环氧地板漆施工中,使用高压无气喷涂能达到比滚涂更好的表观效果。下面来看看环氧地板漆涂料施工高压无气喷涂的注意事项。1、喷涂压力和流量.对某一型号的无气喷涂设备,当使用的涂料私度不变、输入的压缩空气压力一定时,其喷涂压力和流量之间的关系为:流量增大,喷涂压力降低。当输入的压缩空气的压力升高时,喷涂压力和流量便相应增加。

    In the construction of epoxy floor paint, high pressure airless spraying can achieve better appearance than roller coating. Let's take a look at the matters needing attention in the construction of epoxy floor paint for high pressure airless spraying. 1. Spraying pressure and flow. For a certain type of airless spraying equipment, the relationship between spraying pressure and flow rate is that the flow rate increases and the spraying pressure decreases when the coating privacy is unchanged and the input compressed air pressure is constant. When the pressure of compressed air is increased, the spray pressure and flow rate will increase correspondingly.

    2、环氧地板漆涂料黏度与喷涂压力

    2. Viscosity and spray pressure of epoxy floor coatings

    不同类型的涂料黏度不同,高固体分涂料的黏度尤其大,比如无溶剂类高固含量的环氧树脂涂料。黏度越高,施工时需要的喷涂压力越大。一般低黏度涂料的压力比选择23:1、32:1,而高黏度涂料的施工压力比一般在45:1左右。但不能一味增加喷涂的压力,喷涂高黏度涂料时,还应考虑更换大口径的喷嘴。

    Different types of coatings have different viscosity, especially high solid content coatings, such as solvent-free high solid content epoxy resin coatings. The higher the viscosity, the greater the spraying pressure needed during construction. The pressure ratio of low viscosity coatings is 23:1 and 32:1, while the pressure ratio of high viscosity coatings is about 45:1. But can not blindly increase the pressure of spraying, spraying high viscosity paint, should also consider the replacement of large caliber nozzle.

    3、喷嘴的选择

    3. Nozzle selection

    在进行高压无气喷涂前,根据所使用的涂料和喷涂对象,应选择一定孔径和形状的喷嘴。喷嘴的孔径决定了流量的大小,喷嘴的形状则决定了喷雾的幅度。对于你那度较高、所需施工面积较大的涂料,应选择孔径较大的喷嘴。

    Before high-pressure airless spraying, nozzles with certain aperture and shape should be selected according to the coatings and objects used. The size of the nozzle determines the size of the flow, and the shape of the nozzle determines the amplitude of the spray. For those paints with higher size and larger construction area, you should choose larger nozzle.
