发布时间：2016/7/11 17:00:15 | 信息来源：Huizhou jia will electroplating technology co., LTDIn the process of insulation hanger regardless of the paint or insulation method, key points need to pay attention to the following points:
(1) the insulation must be washed off in advance.
If the rack surface stained with dirt in the process of making, hanger and insulation between can obtain bonding firm, and sometimes may immediately blistering off. This rack is an essential first step of washing, insulation in the process.
(2) using thin coating to enhance the bonding strength favorable backing
The bonding strength between coating and substrate is better than the bonding strength between the coating and the coating is not as good as coating on the substrate. Therefore, when the insulation is coated with a diluted coating, and then to dry and then coated with normal consistency of the coating, so as to improve the bonding strength of the coating on the substrate is very favorable.
(3) master the two time of the coating interval
On a coating of plastic film in the not yet fully dry before it is not suitable to brush the next insulating adhesive, otherwise it will not only affect the bonding strength of insulating adhesive, but also affect the appearance quality.
(4) to do a good job in post processing
When the rack coating the insulating glue and the sufficient and dry to do the work of clearing, if non stick part insulation with insulating cement, fully cleaned. Use sandpaper clean. This is to improve the surface cleanliness of the hanger, necessary to ensure the process of plating can pass on the current.
The above is just the requirements of coated insulation. Sometimes also used the polyethylene plastic film or plastic binding, using these methods to bundle compacting shall prevail, for a certain shape complex pieces is not applicable to the, general to round bar bundling. Binding must be pulled tight, so that on the surface of the plastic film or plastic tape and hanging close, not to bath in order to stay in space, or a solution of the process under the pollution also. Bundled with the rear end with a hot iron seal.
