Thermoplastic plastics are the most widely used plastics. They are made of thermoplastic resin as the main component and added with various additives to form plastics. Under certain temperature conditions, the plastics can soften or melt into any shape. The shape is unchanged, this state can be repeated and always has plasticity, and this repetition is just a physical change, making this plastic a thermal plastic. Generally, the molecular weight of polymers in thermoplastics can reach hundreds of thousands to millions. These macromolecules can be linear or branched. The macromolecules are entangled with each other in a disordered or relatively ordered arrangement , Forming a polymorphic structure. Thermoplastics are widely used in electrical, mechanical, construction, daily necessities, etc.
Thermoplastic density measuring instrument is a special density measuring instrument for measuring the density of thermoplastics. Now the instrument will be introduced in detail.
Principle of Thermometer Density Meter 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.
Density meter for thermoplastic density is currently the most widely used digital density measuring instrument with a precision of one-thousandth. Using water as the medium, only two steps can display the density value. Compared with the density meter of traditional thermoplastic density, the machine does not need manual calculation, and the operation is convenient and time-saving, and the measurement is accurate and efficient.
Main uses: Widely used in measuring radio wave machine parts, water pipes, packaging materials, eating utensils, high-grade insulation materials, bearings, chemical resistant pipes, radio housings, paints, etc

Density meter detailed measurement operation steps of thermoplastic density:
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.
