Thermosetting plastics are plastics that can be cured under heat or other conditions or have insoluble (melt) characteristics, such as phenolic plastics,
Epoxy plastic stool. Thermoplastics are divided into two types of formaldehyde cross-linked type and other cross-linked type. Formaldehyde cross-linked plastics include phenolic aldehydes, amino-plastics, and other cross-linked plastics include unsaturated polyesters, epoxy polyesters, collar dimethylallyl acrylate resins, etc. The molecular chains of resins in thermoplastics are all linear or branched structures. There are no chemical bonds between the molecular chains. They soften and flow when heated, and they become hard after cooling. Thermoplastic resins are linear or branched before curing. After curing, the molecular chains form chemical bonds and become a three-dimensional network structure, which cannot be melted or dissolved in a solvent. It is mainly used in thermal insulation, wear resistance, insulation, temperature and high pressure resistant plastics used in harsh environments.
Thermosetting plastic density meter tester is a special instrument for measuring thermosetting plastics. The instrument will be described in detail next
The principle of thermosetting plastic density detector DH-300
This machine adopts Archimedes principle, simple and convenient operation, fast measurement, accurate results, durable, economical and so on. Products comply with ASTM D792, GB / T 1033, HG4-1468, JIS-K-6268, ISO 2781, UL, IEC, CCC, VDE and other national standards.
Thermosetting plastic density detector is the most widely used digital density measuring instrument with the precision of 1/1000. When using water as the medium, only two steps can display the density value. Compared with the traditional thermosetting plastic density detector, this machine does not need manual calculation, which is convenient and time-saving, accurate and efficient.
Main application: Widely used to measure the plastic used in harsh environments such as heat insulation, wear resistance, insulation, high temperature resistance

Thermosetting plastic density detector detailed measurement operation steps:
Block measurement steps
â‘ First measure the weight of the product in the air, press ENTER to store the memory.
â‘¡ Put it in water again to measure the weight in water, press ENTER to store, and display the density value.
Granular measurement steps:
1. Place the tennis ball on the hanging rail in the water, the glass on the measuring table, and press [ZERO].
The key deducts the weight of tennis balls and glasses.
2. Put the sample to be tested into the glass on the measuring table.
3. When the stable symbol is displayed, press the [ENTER] key, [SAVE-A] appears, and then the [------] table appears
It shows that it is in the process of memory, and it points to M (weight in air) after the memory is completed.
4. Use tweezers to take out the tennis ball on the pendant in the water and open it. Pour the sample in the glass into the tennis ball to buckle the tennis ball. (Note that there must be no missing samples).
5. Use tweezers to pick up the tennis ball and clean it in alcohol, shake it with a little force to make sure there are no air bubbles between the particles.
6. Use tweezers to pick up the cleaned sample (tennis ball) and place it on the pendant in the water and put the glass back on the measuring table.
7. When the stable symbol is displayed, press the [ENTER] key, [------] appears, and then [SAVE-B] appears to indicate that it is in the process of memory. After the memory is completed, point to SG, the specific gravity value.
8. After recording the required data, press the [ENTER] key to return to the to-be-tested mode and measure the next sample.
