Dewaxing water background
edit
As the first process of metal electroplating parts pretreatment, the speed and thoroughness of wax removal are of great significance to the production of electroplating line. Therefore, choosing a good dewaxing agent can improve the performance of dewaxing and bring good economic benefits.
Dewaxing water concept explained
edit
Wax removal water is a water-based active substance based, metal corrosion inhibitors, additives as a supplement to the metal corrosion inhibition effect of the component and solvent and other multi-functional cleaning agent, with the emulsification ability of wax dirt and oil cleaning power. With wax removal thoroughly, clean oil removal, no corrosion to the workpiece, no discoloration after cleaning, no oxidation rust function.
Principle of dewaxing water
The wax scale of polishing wax is mainly composed of paraffin wax, fatty acid, loose soap, metal oxide and some inorganic solid polishing small particles such as: corundum, silicon carbide, high aluminum porcelain and so on. The solid particles are distributed uniformly in the polishing wax system in the form of powder, as well as some residual pieces of polishing cloth, polished metal matrix powders and oxides. The wax scale and workpiece are mainly adhered by mechanical adhesion, intermolecular force adhesion, electrostatic force adhesion and other adhesion methods. When the wax scale particles of mechanical adhesion are smaller than 011μm, it is difficult to remove. This is the conclusion obtained from the observation of various wax scale for a long time. The key to the preparation of wax removal water is the reasonable combination of various active substances, additives, corrosion inhibitors, etc., by reducing the workpiece surface tension, improve the wetting permeability and emulsification, dissolution, solubilization and other properties, so as to strengthen the permeability and dissolution capacity, to achieve the wax removal performance.
A high quality dewaxing water must have good comprehensive performance. Its dewaxing ability, rust prevention, defoaming and stability are four important technical indexes to evaluate the quality of dewaxing water. After rust prevention, defoaming and stability meet the requirements of use, the index of wax removal ability is a decisive index to evaluate the quality of the wax removal water. The dewaxing ability is determined by the type, quantity and compound of the active substance in the formula of dewaxing water. [1]
Dewaxing water action
Dewaxing water is widely used in electroplating, watches, crafts, jewelry and other hardware industry after polishing of the workpiece wax removal process. Wax removal water is mainly composed of surfactants, additives, corrosion inhibitors, co-solvents and other composite deployment, so that the product at room temperature, heating, ultrasonic, immersion and other processes can quickly and thoroughly remove all kinds of wax scale, stainless steel, carbon steel, zinc alloy, aluminum alloy, magnesium alloy, copper alloy and other substrates do not produce corrosion, oxidation and other negative effects, has a long service life and environmental performance. In addition, attention should be paid to the reasonable allocation of product viscosity, odor, color, transparency and other appearance properties to meet the psychological needs of customers and improve the added value of products.
Dewaxing water application and status
The dewaxing water has the ability of removing emulsification of waxy dirt and cleaning power of oil. With wax removal thoroughly, oil removal clean, no corrosion to the workpiece, no discoloration after cleaning, no oxidation rust, more economic and environmental protection than the use of trichloroethylene and non-toxic. This product is suitable for cleaning all kinds of metal workpiece after polishing.
Wax removal water is through active substances, additives, corrosion inhibitors, co-solvents and other composite, the preparation of products. At normal temperature, medium temperature, ultrasonic, immersion and other processing processes can quickly and thoroughly remove all kinds of wax scale, oil, wax removal water because of the active substance in the product, the consistency can reach more than 3000, and the consistency principle is different from that of dishwashing detergent, dishwashing detergent added thickening ingredients, and the consistency of wax removal water is completely derived from the content of active substance, with the quality instrument detection, Usually content in more than 60 wax removal water rendering
Dewaxing water type
Dewaxing water according to PH can be divided into alkali type dewaxing water, neutral dewaxing water, and acid dewaxing water, for different workpiece, have their own advantages, stainless steel parts strong corrosion resistance, do not belong to active metal, and alkaline dewaxing water is just suitable, its durability, dewaxing strength will be better than neutral dewaxing water and acid dewaxing water, neutral dewaxing water is generally used for active metal, Such as six series seven series aluminum alloy, magnesium alloy, zinc alloy and copper wax removal, acid wax removal water cleaning out the product is good hydrophobicity, for hydrophobic products with high requirements, acid wax removal water is more suitable
Method of using wax removal water
edit
Generally need to be warmed to more than 80 degrees immersion or ultrasonic cleaning, one to ten minutes can be clean wax scale.
Wide range of application, stainless steel products, copper, aluminum and other alloy products are applicable, such as watchband watchcase, glasses frame, foot wire, metal accessories and ornaments;
Strong penetration and dissolution ability, fast wax removal speed;
Does not contain sodium hydroxide and inorganic salt, does not damage the base material;
Using concentration (2~5%) high oil tolerance, and can be used as oil removal and degreasing products, long life, economic and practical.
Usage: When preparing the solution, add the water into a clean tank and heat it to more than 60℃. Then stir well and add the wax removal water XCY-1008A (less than 100℃) at the required temperature at a ratio of 1:20. In order to get the best cleaning effect, according to the cleaning object and the degree of dirt, can also reduce the proportion of water, temperature to 80℃ combined with ultrasonic equipment cleaning for 3 to 10 minutes, rinsed with pure water and then dried. When cleaning by hot soaking and hand wiping, the workpiece should be shaken continuously until it is clean.
Wax removal water precautions
edit
In order to maintain the best cleaning effect, the cleaning workpiece shall not overlap each other, and 1 ~ 3% wax removal water should be added regularly every day.
The same cleaning tank can not clean different metal polishing workpiece surface wax scale, because of the different activity of different metals, in the cleaning process due to heating will produce different oxidation effect, and different metals in the same cleaning tank cleaning, there will be metal ions of active metal attached to the inactive metal surface. Wax removal water cleaning zinc alloy active workpiece, pay attention to cleaning time should not be too long, cleaning temperature should not exceed 85 degrees Celsius, otherwise the workpiece will produce light corrosion phenomenon.
When the wax scale suspension of the cleaning tank increases significantly and reaches basic saturation, the wax removal cleaning effect decreases significantly, and the wax removal water needs to be added in time to maintain. When the amount of wax and oil is too much, the cleaning fluid needs to be replaced, depending on the cleaning of the workpiece, the general replacement cycle is 2 ~ 10 days.
When the workpiece has heavy oil dirt, it should be cleaned in the wax removal water cleaning tank and rinsed in 0.5-1% alkali water for 30 seconds to 1 minute.
After the cleaning solution works for a certain time, the wax slag in the cleaning tank can be filtered and used again, or the filtered cleaning solution can be better used as crude lotion, which can make full use of the cleaning solution to reduce the cleaning cost.
Characteristics of waxed aquatic products
edit
Dewaxing water must have good comprehensive properties. Dewaxing ability, rust shear property, low bubble property, stability and no corrosion are the main indexes to evaluate the quality of dewaxing water.
Rust resistance: The product is required to be cleaned, with the ability to prevent rust between processes.
Low foam: Because the general use of wax removal process for ultrasonic cleaning, so the need to remove wax water must be very low foam height, to prevent too much foam affect the use of the product effect.
Stability: The product is required to be used at high temperature without precipitate, flocculation, stratification and other adverse elements. At the same time, the product should have strong processing capacity.
Non-corrosive: Because polishing parts are generally polished products, the appearance of corruption and gloss conditions are very high, so, wax removal water must have no corrosion on all kinds of metal workpiece, do not make the workpiece discoloration ability.
With the above four technical standards at the same time, the dewaxing water dewaxing function is to evaluate the quality of the dewaxing water decision standard. However, the dewaxing effect depends on the selection type, number and compound of the active substance in the dewaxing water formula. The selection of simple active matter as detergent, its washing ability and foam property is generally not ideal, the application of two or more kinds of active matter compound, not only can promote the dirt removal performance, and the compound product foam performance is good, convenient rinsing, and its rust resistance and corrosion resistance have been improved.
