Labratory and Quality Control Unit
In order to fulfill the slogan of “engineering the properties of our specialty” of Sam Polymer Bonyan Company and quality reproducibility, it is necessary to enter the raw materials into the factory and manufactured products continuously before production and during production with different physical, mechanical, thermal and … Be examined. Sam Polymer Bonyan Company, with a wide range of devices and equipment, has the ability to perform the necessary tests to fulfill the slogan and repeatable quality of its products.
1. Measured mechanical properties, which include tensile, flexural and impact properties, are measured by universal devices and impact testers.
-
Tensile and flexural properties are directly related and the higher they are, the more suitable they are for applications under higher load and pressure.
-
Impactability is inversely related to tensile and bending, and the higher the value, the higher the energy attenuation and is used for applications such as energy dumping, sound, etc.
2. Physical properties are measured by melt flow index and hardness tester. Shrinkage is also measured using a special mold and caliper and micrometer.
-
Melt flow index is used to measure the viscosity and molecular mass (flow) of plastic. The higher the molecular mass and viscosity, the lower the number.
-
Hardness tester is also used to measure the hardness of plastics and rubber with Shore D and Shore A. The softer the material and the higher the elasticity and the less filler and crystallinity it has, the less hard it is.
-
Shrinkage is measured for the shrinkage of the polymer melt of different compounds. The higher the amount of filler and reinforcer and the more tensile, bending and chemical structure the polymer has with the polar functional groups, the less shrinkage.
3. Thermal properties are measured by HDT-Vicat andDSC devices.
-
The higher the polarity of the polymer with the higher the ability to interact and the higher the bending and bending, the higher the HDT,so they are used to produce parts that require a higher service temperature.
-
To evaluate the thermal stability of polyolefins, by DSC device OITtest It is taken to show the stability of the polymer against oxidation. The higher this value, the longer the life of the final part.
4. Spectrophotometer and light cabin are used for color measurement and color matching.
-
A spectrophotometer is used to match the light of the input to the laboratory and the replicated sample, which presents the color in three parameters: white, black, yellow, blue, red, and green, based on which the desired color is analyzed.
-
The light cabin device is also used to match the colors visually.
5. Furnaces are used to check the ash content of products and inputs.
6. DSC device is used to check the input polymers and their purity percentage and identify unknown samples.
