一、齿轮泵表面粘涂原理及特点 近年来表面粘涂技术我国设备维修得到了广泛应用，适用于各种材质零件设备修补。其工作原理将加入二硫化钼、金属粉末、陶瓷粉末纤维等特殊填料胶粘剂，直接涂敷于材料或零件表面，使之具有耐磨、耐蚀等功能，主要用于表面强化修复。它工艺简单、方便灵活、安全可靠，不需要专门设备，只需将配好胶涂敷于清理好零件表面，待固化后进行修整即可，常室温下操作，不会使零件产生热功当量影响变形等。 二、粘涂层涂敷工艺 轴套外圆、轴套端面贴合面、齿轮端面或泵壳内孔小面积均匀性磨损量0.15-0.50mm之间、划痕深度0.2mm以上时，宜采用粘涂修补工艺。粘涂层涂敷工艺过程：初清洗→预加工→{zh1}清洗及活化处理→配制修补剂→涂敷→固化→修整、清理或后加工。 粘涂工艺虽然比较简单，但实际施工要求却相当严格，仅凭选择好胶粘剂，不一定能获得高粘涂强度。既要选择合适胶粘剂，还要严格地按照正确工艺方法进行粘涂合适胶粘剂，还要严格地按照正确工艺方法理行粘涂才能获得满意粘涂效果。 （一）涂敷 用修补剂先粘修表面上薄涂一层，反复刮擦使之与零件充分浸润，然后均匀涂至规定尺寸，并留出精加工余量。涂敷尽可能朝一个方向移动，往复涂敷会将空气包裹于胶内形成气泡或气孔。 （二）预加工 用细砂纸磨成一定沟槽网状，露出基体本色。 （三）{zh1}清洗及活化处理 用丙酮或专门清洗剂进行。然后用喷砂、火焰或化学方法处理，提高表面活性。 （四）修整、清理或后加工 进行精镗或用什锦锉、细砂纸、油石将粘修面精加工至所需尺寸 （五）配制修补剂 修补剂使用时要严格按规定比例将本剂（A）固化剂（B）充分混合，以颜色一致为好，并规定时间内用完，随用随配。 （六）初清洗 零件表面{jd1}不能有油脂、水、锈迹、尘土等。应先用汽油、柴油或煤油粗洗，{zh1}用丙酮清洗。 （七）固化 用涂有脱模剂钢板压工作上，一般室温固化需24小时，加温固化（约80℃）需2-3小时。

1, the gear pump principle and characteristics of surface coating In recent years, surface coating of our equipment maintenance has been widely used for a variety of materials spare parts and equipment repair. It works to join the molybdenum disulfide, metal powder, ceramic powder filler fiber and other special adhesive coating on the materials or components directly to the surface, so that with wear, corrosion and other functions, mainly used for surface hardening repair. It process simple, convenient and flexible, safe and reliable, no special equipment, just with good adhesive coating on the cleared part surface can be trimmed after curing, constant room temperature operation, does not make parts produce mechanical equivalent of heat impact deformation. Second, sticky coating coating process Cylindrical sleeve, sleeve end fitting surface, the gear pump shell hole end or even a small area of 0.15-0.50mm of wear between the scratch depth of 0.2mm or more, should fix withsticky coating process. Adhesive coating during the coating process: first pre-processing → Cleaning → activation → final cleaning and preparation of repair agent curing → → → coating finishing, cleaning or after processing. Cohering technique is a relatively simple, but the actual construction requirements are very strict, a good adhesive choice alone does not necessarily have access to high-viscosity coating strength. We must choose the right adhesive, but also strictly in accordance with the correct method of cohering technique suitable adhesive, but also strictly in accordance with proper methods of handling line process to a satisfactory coating of adhesive coating effect. (A) Coated Putty stick with the first thin coat repair the surface, repeated scratching with the components to make the full invasion, and then uniformly coated to the required size, and precision machining allowance set aside. Coating as moving in one direction, reciprocating air parcels in the plastic coating will form a bubble or pore within. (B) pre-processing Ground into a certain groove with fine sandpaper network, exposing the substrate character. (C) the final cleaning and activation With acetone or specialized cleaning agents. Then sandblasting, flame or chemical means, and improve the surface activity. (D) repair, cleaning or after processing For fine boring or needle files, fine sandpaper, sharpening stone will stick to the required size shaving finish (E) preparation of Putty Putty when used strictly in accordance with the provisions of proportion to the agent (A) curing agent (B) well-mixed, color-line as well, and used within the specified time, with the use allocation. (F) Initial cleaning Part surface must not have oil, water, rust, dust, etc.. Should use gasoline, diesel or kerosene rough wash, and finally washed with acetone. (G) curing Pressure plate coated with release agent with the work, generally take 24 hours at room temperature curing, heat curing (about 80 ℃) take 2-3 hours.
