Cleaning agent

Abstract

The invention discloses a cleaning agent. The cleaning agent comprises the following materials in percentage by weight: 1 to 6% of potassium silicate, 2 to 7% of tripoly-sodium silicate, 1 to 5% of sodium carbonate, 0.5 to 3% of potassium oleate, 0.5 to 3% of alkaryl polyether, 0.5 to 3% of sodium gluconate, 0.5 to 3% of tetrasodium ethylenediamine tetraacetate, 0.5 to 3% of an antifoaming agent, 0.5 to 3% of a corrosion inhibitor, and the balance of water. According to the mode mentioned above, the cleaning agent provided by the invention has the formula adopting components without smell and toxicity, the residual scaling powder and the residual rosin can be permanently decomposed and fallen, the residual greasy dirt can be removed and dissolved, and the foam can be effectively removed; and the cleaning agent has the corrosion protection effect, is remarkable in the cleaning effect and is durable, and is an environment-friendly cleaning agent with reasonable price and high cost performance.

Description

technical field [0001] The invention relates to a cleaning agent, in particular to a cleaning agent used for cleaning flux, rosin and oil stain residues. Background technique [0002] Electronic circuit surface mount technology (SMT) is a circuit assembly that mounts non-lead or short-lead surface mount components on the surface of a printed circuit board or other substrates, and solders and assembles them by reflow soldering or dip soldering. even technology. With the rapid development of the SMT industry, a large number of used reflow furnaces, wave soldering furnaces, various fixtures, production lines and various equipment parts will be produced in the production process. There are flux, rosin and oil residues in these equipment , need cleaning agent to maintain and clean in time. [0003] At present, many domestic manufacturers use German and American brands of cleaning agents, but foreign brands are expensive and increase production costs. Although domestic cleaning...

Problems solved by technology

Although domestic cleaning agents are cheap, their cleaning effect is poor, they are used for a short time, they are prone to foam, and they need to be washed with a lot of water. The cleaning process has a strong smell and is highly corrosive, which will have a negative impact on the equipment during the cleaning process.
