With the development of technology and the improvement of environmental protection requirements, in the production process of automobiles and parts, the parts cleaning process also puts forward higher requirements for cleaning equipment and cleaning agents. The general requirements for cleaning automobiles metal parts are as follows: the cleaning speed is fast, and the dirt on the metal surface can be completely removed within the cleaning time set by the cleaning machine process; No corrosion to the cleaning machine and cleaned parts; The cleaning agent has the advantages of low cost, environmental protection and mild smell; During the cleaning process, no insoluble matter remains on the surface of the cleaning object, no new dirt is generated, no new covering layer harmful to subsequent processes is formed, and the product quality is not affected.

工程師推薦清洗劑時不僅（jǐn）要滿足工藝要求，還必須在清（qīng）洗（xǐ）設備及清洗方式、清洗（xǐ）零部件材質、零件表麵汙垢類型以及下一道工（gōng）序、水質和車間環（huán）境等眾多要素（sù）之間做到權衡。

When recommending cleaning agent, the Engineer shall not only meet the process requirements, but also make a trade-off between many factors such as cleaning equipment and cleaning method, cleaning part material, part surface dirt type, next process, water quality and workshop environment.

常用的清（qīng）洗設備包括：浸入式清洗、噴淋清洗、高壓噴淋清洗以及超聲波清洗設備。

Common cleaning equipment includes immersion cleaning, spray cleaning, high-pressure spray cleaning and ultrasonic cleaning equipment.

浸入式清洗一（yī）般清（qīng）洗的（de）零部件為多腔體，要求清洗劑具有較強的清洗能力，對（duì）於清洗劑消泡性能要求不高，但要求清洗劑（jì）具有一定的乳化雜油的能力，這樣（yàng）才能保障零部（bù）件在清（qīng）洗（xǐ）並被取出清洗（xǐ）劑後不會被清洗（xǐ）掉的雜油二次汙染其表麵。乳化雜油能力（lì）強的清（qīng）洗劑（jì）缺點是清洗劑清洗能力逐步降低，導致清洗劑使用壽命較短。

Generally, the parts to be cleaned by immersion cleaning are multi cavity, which requires the cleaning agent to have strong cleaning ability, and the defoaming performance of the cleaning agent is not high, but the cleaning agent is required to have a certain ability to emulsify miscellaneous oil, so as to ensure that the surface of the parts will not be polluted by the cleaned miscellaneous oil after the cleaning agent is taken out. The disadvantage of the cleaning agent with strong emulsified miscellaneous oil ability is that the cleaning ability of the cleaning agent is gradually reduced, resulting in short service life of the cleaning agent.

汽（qì）車變（biàn）速（sù）器零部件的（de）清（qīng）洗大多采用通過式噴淋清洗機，一般分為清洗—漂洗—烘（hōng）幹三個過程，個別情（qíng）況根（gēn）據（jù）工藝要求而變化，清洗—清洗—漂（piāo）洗—烘幹或（huò）清洗—漂洗（xǐ）—漂洗—烘幹。噴淋清洗機配有（yǒu）撇油器，采用（yòng）抗（kàng）雜油能力較強的清洗劑可（kě）以提高清洗劑的使用壽命。如清洗的變速器零部件材質一（yī）般（bān）為鍛鋼（gāng），零部件（jiàn）表麵（miàn）汙物多為低粘度切削液，選用清洗劑時在考（kǎo）慮清洗能力的同時要考（kǎo）慮清（qīng）洗劑的（de）消（xiāo）泡能力，一般情況下，隨著清（qīng）洗劑溫度的升（shēng）高，其去汙（wū）能力也隨之提高，但（dàn）超（chāo）過一定溫（wēn）度後，去汙（wū）能力反而下降，推薦（jiàn）清洗劑時要考慮一個適宜的溫（wēn）度範圍。另一（yī）方麵，由於漂洗清洗劑（jì）濃度（dù）一般較低，範圍在0.5%～1.5%，要求清洗劑具有較好的防鏽（xiù）能力。

The cleaning of automobiles transmission parts mostly adopts the through spray cleaning machine, which is generally divided into three processes: cleaning rinsing drying. Individual conditions change according to the process requirements, cleaning cleaning rinsing drying or cleaning rinsing rinsing rinsing drying. The spray cleaning machine is equipped with an oil skimmer. The use of cleaning agent with strong anti impurity oil ability can improve the service life of the cleaning agent. For example, the cleaned transmission parts are generally made of forged steel, and the dirt on the surface of the parts is mostly low viscosity cutting fluid. When selecting the cleaning agent, the defoaming ability of the cleaning agent should be considered while considering the cleaning ability. Generally, the decontamination ability increases with the increase of the temperature of the cleaning agent, but the decontamination ability decreases after exceeding a certain temperature, An optimum temperature range should be considered when recommending cleaning agents. On the other hand, because the concentration of rinsing cleaning agent is generally low, ranging from 0.5% to 1.5%, the cleaning agent is required to have good anti rust ability.

高壓噴淋清洗機在去除零部件表麵汙物（wù）的同時（shí）還可去除金屬表麵毛刺，零件多采用定位和定點噴（pēn）淋方式，要求清洗劑在高壓下有很好的抵抗泡沫能力。

High pressure spray cleaning machine can remove metal surface burrs while removing the dirt on the surface of the components, and the parts are mostly positioned and fixed spray. The cleaning agent is required to resist foam at high pressure.

一些特（tè）定工藝條件下，推薦清（qīng）洗（xǐ）劑時必（bì）須要考慮對後麵工序的影響，如（rú）在某變速器軸、齒生產工藝流程中：磨齒—噴淋清（qīng）洗（中間清洗）—拋丸—噴淋清洗（終洗），其中噴淋中間清洗過程要考慮（lǜ），清洗劑清洗零件烘幹後，零部件表（biǎo）麵不能有粘性清洗劑殘留或（huò）覆蓋膜。。

Under some specific process conditions, the impact on subsequent processes must be considered when recommending cleaning agent, such as on a transmission shaft In the tooth production process: gear grinding - spray cleaning (intermediate cleaning) - shot blasting - spray cleaning (final cleaning), which shall be considered in the spray intermediate cleaning process. After the parts are cleaned with cleaning agent and dried, there shall be no viscous cleaning agent residue or covering film on the surface of the parts..

91污都知道，清洗劑（jì）主要是用於去（qù）除工件表麵的切削液、磨灰以及金屬顆粒物等，並提供短（duǎn）期（qī）的防鏽作用。一般清洗劑（jì）的防鏽能力在濕度、溫度高的（de）車間條件下，不足以保證工序間防鏽，特別是在夏（xià）季車間（jiān）濕度、溫度較高的情況下（xià）。

As we all know, cleaning agents are mainly used to remove cutting fluid, grinding ash and metal particles on the workpiece surface, and provide short-term rust prevention. The antirust ability of general cleaning agents is not enough to ensure the antirust between processes under the workshop conditions of high humidity and temperature, especially under the conditions of high humidity and temperature in the workshop in summer.
