1 喷漆之前外表遭到污染（如蜡、矽、油、水、锈，流出之焊接物及空气污染等）。
1 painting before the appearance of pollution (such as wax, silicon, oil, water, rust, outflow of welding and air pollution, etc.).
2 运用对底材或面漆不适合的漆料。
2 the use of paint is not suitable for substrate or topcoat.
3 干喷底漆（含粉量过高、树脂成膜物缺乏）
3 dry primer (powder content is too high, lack of resin film)
4 运用便宜稀释剂溶解力缺乏。
4 the use of cheap diluent dissolving power shortage.
5 涂膜过薄。
5 thin film.
解决方法：
Resolvent：
1 彻底清除被涂物外表残留之一切污物。
1 thoroughly remove all dirt from the surface of the coating.
2 选用准确适宜的底漆。
2 choose the appropriate primer.
3 杰出之底漆喷涂，防止干喷（粗膜）
3 excellent primer spray to prevent dry spray (thick film)
4 运用合格杰出的稀释剂。
4 the use of qualified good diluent.
涂装技术平面规划图规划的好坏，对涂装线的运用至关重要。假如规划不妥，即便各项单台设备制作得再好，整条出产线也欠好运用。
The application of coating technology is very important to the application of the painting line. If the planning is wrong, even if the production of a single device again good, the whole production line is not good to use.
现将喷塑烤房平面规划图图多见的典型过错列举如下，供参阅。
The typical fault spray barn planning Tutu see listed below, for reference.
1、产值达不到规划纲要：有的规划不思考吊挂方法，不思考吊挂距离，不思考上下坡、水平转弯干涉，出产时间不思考废品率、设备利用率、商品顶峰出产才能。导致产值达不到规划纲要。
1, the output value is not up to the plan: some planning thinking hanging method, not thinking of hanging distance, not thinking of interference on the downhill, horizontal curve, production time without thinking the rejection rate, equipment utilization rate, commodity production to peak. Resulting in less than the output plan.
2、技术时刻不行：有的规划为了下降造价，经过削减技术时刻来到达意图。多见的如：前处理过渡段时刻不行，形成串液；固化时未思考升温时刻，形成固化不良；喷漆流平时刻不行，形成漆膜流平不行；固化后冷却不行，喷漆（或下件）时工件过热。
2, no moment: some planning in order to decrease cost, after cutting time to express map. See more such as: the pretreatment time not formed on the transition section, liquid; curing without thinking of heating time, the formation of bad curing paint; leveling time no film formation leveling; after curing cooling no, paint (or pieces) when the workpiece overheating.
3、运送设备规划不妥：工件的运送方法有多种，规划不妥，对出产才能、技术操作、上下件都会产生不良后果。多见的有悬挂链运送，其负载才能、牵引才能都需求核算和干涉绘图。链条的速度对设备的配套也要有相应的请求。涂装设备对链条的平稳性、同步性也有请求。
3, transport equipment planning is not correct: there are a variety of delivery methods, planning, production capacity, technical operation, the upper and lower parts will have adverse consequences. There are more than a suspended chain transport, its load capacity, traction capacity accounting and interference mapping. The speed of the chain of equipment must have the corresponding request. Coating equipment for the stability of the chain, synchronization also request.
4、设备选型不妥：因为商品的请求不同，设备选型也有所不同，而各种设备有其长处，也有其缺点。而规划时不能向用户阐明，制作后发现很不满足。例如，喷粉烘道用风幕隔热、洁净度请求的工件未装置净化设备等。这类过错是涂装线最多见的过错。
4, equipment selection is wrong: because of the different requirements of the goods, equipment selection is also different, and a variety of equipment has its advantages, but also has its shortcomings. The planning can not be clarified to the user, the production was found to be very satisfied. For example, dusting oven workpiece with heat insulation, the cleanliness of the air curtain device request not purification equipment etc.. This type of fault is the most common fault of the coating line.
5、设备的技术参数挑选不妥：当时涂装线因为技术参数挑选过错的比较多见，一是单台设备的规划参数选用下限，二是对设备体系的配套性不行注重，三是底子没有规划彻底拍脑袋。
5 technical parameters and equipment selection was wrong: painting line because of technical parameters for choosing fault more common, one is the lower limit of the planning parameters of single equipment, two is not on the supporting equipment system focusing on three is no planning completely clap.
6、配套设备缺项：涂装线关联设备较多，有时为了下降报价，就省去了一些设备。也没能向用户阐明，形成扯皮。多见的有前处理供热设备、喷涂设备、气源设备、排气管道设备、环保设备等。
6, lack of supporting equipment: coating line associated equipment more, and sometimes in order to reduce the price, it eliminates some equipment. Has not been able to clarify to the user, the formation of wrangling. There are a lot of pre-treatment heating equipment, spraying equipment, gas equipment, exhaust pipe equipment, environmental protection equipment, etc..
7、未思考设备节能问题：当时，能源价格变化很快，而规划时，未能思考这些疑问，使得用户出产成本较高，有些用户不得不在运用较短时刻内重新改造和采购设备。
7, did not think such: at that time, the energy price changes quickly, and planning, not to think about these questions, so that the user cost of production is high, some users have to use a shorter time to renovation and purchase of equipment.
