Hot press cleaning

Thread Content

During normal operation of heat transfer oil hot pressing plates (heat transfer oil pressing machines), the heat transfer fluid, namely heat transfer oil, undergoes a series of physicochemical changes over time as a result of prolonged use. Parameters such as viscosity, residue carbon content, and acid value increase, and significant amounts of fouling in the form of coking and carbonization occur within the system. This affects the proper functioning of the system to some extent, leading to reduced flow rates and insufficient heating temperatures, which in turn has an impact on the production equipment. If the heat distribution on the hot pressing plate is uneven, it prevents the plate from functioning properly. To this end, effective cleaning methods must be employed to remove deposits such as coking and carbonization from the inner walls of the heat transfer oil press, in order to achieve uniform temperature. Based on the actual operating conditions of heat transfer oil pressing machines, Shandong Kaidi Chemical has, through years of effort, developed a heat transfer oil cleaning agent suitable for cleaning such machines – the KD-L212 heat transfer oil pressing machine cleaner. KD-L212 is a cleaning agent for heat transfer oil hot-press machines, designed specifically to effectively remove oil coking, scaling, and carbonized deposits that form in the system over time when different grades of heat transfer oil are used as the heat carrier. Through powerful penetration, stripping, and dissolving actions, it removes and loosens oil deposits as well as other mineral deposits, dissolving them so that they remain suspended in the solution and can be expelled. It can effectively address the uneven heat transfer in hot-press plates, and it is also capable of removing the carbides and coking particles mixed in with the oil dirt. Ensure that the descaling rate is above 90%, that no corrosion or adverse effects occur on the equipment during cleaning, and that it is safe for human use. Product characteristics: (This product has a solvent odor; it is a colorless and transparent liquid with a specific gravity of 1.15±0.05, and it is non-flammable.) ) 1. Safety: non-toxic, non-corrosive, and non-flammable. 2. Easy to use, requiring no heating or mechanical stirring. 3. Economy: Reusable. 4. Non-flammable, non-explosive, non-toxic and harmless, along with a fast dissolution rate and low volatility, are the typical characteristics of this product. 5. The dissolution rate of coke is much higher than that of similar products, while its volatilization rate is much lower than that of similar products. Application range: Removal of oil scale and carbon deposits from heat transfer oil presses, pressing machines, roller presses, heat transfer oil furnaces, pipelines, and heat transfer oil systems. Usage: 1. Drain the remaining heat transfer oil from the system. 2. Connect the pressing machine to an external circulation pump and a circulation tank to form a circulation system. 2. After adding the KD-L212 heat transfer oil hot-pressing machine cleaner of Shandong Kaidi brand to the circulation tank, circulate and clean for 2–4 hours, then discharge the cleaning waste liquid. If the carbon deposit layer is more than 4-5 millimeters thick, the soaking and cyclic cleaning time can be appropriately extended to 4-6 hours. Be sure to maintain a certain pressure within the system during discharge, so that the accumulated carbon deposits can be discharged smoothly and pipe blockages can be avoided. 3. After cleaning with the Shandong Kaidi KD-L212 heat transfer oil hot press cleaner, there is no need for rinsing with water; once the surface is dry, heat transfer oil can be added directly and the machine can be started for use. Precautions: 1. This product has a strong degreasing effect; wear rubber gloves when using it for extended periods of time ; If it accidentally gets on the skin, wash it off with clean water. 2. This product is volatile; please ensure good ventilation when using it ; Make sure to keep it sealed when storing. 3. Standard packaging: 25 kg/plastic drum, 200 kg/iron drum ; It is also available in 5 kilograms per iron drum (for sample testing purposes). If you have any product requirements or questions, please call the Technical Center of Kaidi Chemical’s Industrial Cleaning Division to obtain cleaning solutions and quotes. The manufacturer supplies directly to customers’ factories (Shandong hot press cleaner, Jinan hot press cleaner, Zibo hot press cleaner, Dongying hot press cleaner, Hebei hot press cleaner, Tangshan hot press cleaner, Baoding hot press cleaner, Shijiazhuang hot press cleaner, Wuxi hot press cleaner, Tianjin hot press cleaner, Inner Mongolia hot press cleaner, Xinjiang hot press cleaner, Linyi hot press cleaner, Pizhou hot press cleaner, Langfang hot press cleaner), with 100% guarantee for product quality and technical expertise!

The wood veneer hot-pressing machine is one of the key devices in the particle board production process. Currently, heat transfer oil is widely used as a heat transfer medium in China. Over time, this oil tends to form deposits and carbon buildup to varying degrees, which reduces the efficiency of board production as well as the quality of the finished products. This occurs because the deposits and carbon buildup inside the hot-pressing machine prevent proper heat exchange. So, are there any effective cleaning methods for dealing with such deposits and carbon buildup once they appear? Let’s find out together. Coking of heat transfer oil generally occurs due to the deterioration of the oil. There are many factors that can cause such deterioration, which will not be listed here one by one. However, once the heat transfer oil deteriorates, coking, carbon deposition, and sludge are bound to form. These substances have strong adhesion and poor fluidity, and they are the main reasons behind the reduced efficiency of heat exchange in heat transfer oil. Currently, in China, alkaline cleaners mixed with water are commonly used to clean equipment, but this method has many drawbacks, such as incomplete cleaning, long processing times, and difficulties in disposing of wastewater. Especially with the increased strictness of environmental regulations, it is even more difficult to handle the wastewater generated after cleaning. To address this issue, after conducting practical tests based on foreign cleaning methods, we found two effective cleaning approaches. The first is solvent cleaning; here, the professional hot-press cleaner SP-402 is used in the system for soaking and cleaning. The cleaning process is similar to traditional water washing, except that heating is not required – the cleaner can be used at room temperature. Compared to traditional water-based cleaners, this method offers thorough cleaning without residues, produces less wastewater, and allows the cleaner to be reused. It also takes less time to complete the cleaning process. The second cleaning method is online cleaning. The greatest advantage of this method is that it allows for cleaning the equipment without having to stop production. Currently, many manufacturers abroad use online cleaning agents, and such agents are now being used in China as well (for example, the SP-304 heat transfer oil online cleaning agent produced by Zibo Haoyuan). Based on various cases, it has been found that the cleanliness of equipment after online cleaning can reach over 95%, which allows companies to reduce cleaning costs by 20–35%. Moreover, no waste is generated as a result of this cleaning process, making it highly environmentally friendly. In Europe and the United States, online cleaners are not only used as cleaning agents but also as oil protectants. Data shows that adding an appropriate amount of online cleaner annually can effectively extend the service life of heat transfer oils by one to two years. Through the above introduction, many friends must have gained a new understanding of cleaning hot press machines. So where can these two cleaning products be purchased?
