Application
The lab manual hot press is a versatile tool that can be used for a variety of applications. Powder samples, granular samples, polymer materials, or plastic film materials can all be pressed using this press. Hot pressing can be used to reveal changes in the sample under high temperature and high pressure. This press is a valuable tool for any researcher investigating the properties of materials.
After being heated and pressurized, the chemical stability of the sample particles or powder is improved, which is not easy to be broken and is conducive to cutting and preservation. This treatment can also enhance the adhesion of the powder to the binder, and improve the performance of the products made of it.
The hot press is mainly used in some laboratories and units that need to prepare or test powder samples, particle samples, plastic films and other solid samples at high temperature and high pressure. The hot press can be used to prepare samples for X-ray diffraction analysis, BET specific surface area analysis and infrared absorption analysis. It is an important device for the research and development of new materials.
The hot manual press is perfectly suitable for engineering and technical personnel of colleges and universities and research institutes to carry out spectrum detection and qualitative analysis. It can also be used in the production process of many products to determine the aromatic content of raw materials and products. In addition, it is an indispensable instrument in the field of food safety and quality control.
Maintenance of manual hot press
Keep flat and clean
If the surface of the hot press plate is not flat or clean, it will damage the hot press plate. Hard metal objects are not allowed to enter so as not to damage the hot press plate.
Do not load different sizes of slabs into the hot press at the same time, as this can cause deformation of the hot press and hot press plate. It is best to load the hot press with slabs of the same size, so that they can be evenly pressed and heated, resulting in a better finish product.
Clean the upper and lower linings
The upper and lower liner of the hot press plate is to protect the surface of the hot press plate, and the upper liner plate directly affects the quality of the plate surface. The material of the upper liner is required to have good toughness, wear resistance and heat resistance. The surface of the upper liner should be flat and smooth, so that the plate surface will not be scratched during hot pressing, and the plate surface will be bright after hot pressing.
If you don't regularly clean between the liner and hot press plate, it's easy for fibers and other dirt to get trapped. Over time, this can cause the machine to function less effectively. To keep your machine running smoothly, it's important to remove the liner and clean away any dirt buildup regularly.
The upper liner plate of a Lab Manual hot press is generally changed once a week. This helps to polish the surface and ensure the quality of the finished board surface. It also helps to prevent any dirt or debris from build up on the surface of the board.
Pad the fiberboard
Before pressing the upper liner into place, be sure to pad the fiberboard beneath it. This will help prevent the liner from becoming damaged during installation.
If the heat press is not working correctly, it can cause the transfer to be misaligned or not adhere to the substrate. If you are having problems with your heat press,make sure that the platens are the same size and that they are lined up correctly.
Direct pressing of fibreboard without a liner is not permitted. This is because the adhesive in fibreboard can seep through the paper and ruin the press. In addition, the press could get damaged if the fibreboard is not properly supported.
If the shutdown time is long, it is necessary to remove the steam condensed water in the hot pressing plate in time to avoid its internal corrosion. The steam condensed water can be discharged through the drain valve at the bottom of the hot pressing plate. After the steam condensed water is discharged, the drain valve should be closed and the surface of the hot pressing plate should be wiped dry to prevent rust.
