The YJ-8143 Shellac Ash Tester is designed and manufactured in accordance with the requirements specified in the determination of ash content in the standard GB/T 8143 "Test Methods for Shellac Products", and is applicable to determining the ash content of shellac by the method specified in the standard. Test Principle: The sample is carbonized, incinerated at high temperature, ashed, weighed, and the ash content is calculated.
I. Main Technical Features of the YJ-8143 Shellac Ash Tester:
1. This instrument consists of three parts: a high-temperature heating furnace, a temperature control console, and an electric furnace. It has a small volume and occupies little space.
2. The heating furnace adopts an integrated structure, special refractory materials and heating components, with short heating time and long service life. The whole machine is beautifully designed. The inner furnace lining is a rectangular integral lining made of high-aluminum silicon carbide refractory material.
3. The temperature control console adopts an adjustable digital display controller, with small temperature overshoot and stable and accurate temperature control.
4. The spiral heating element wound from iron-chromium-aluminum alloy wire is inserted into the wire slots on the upper, lower, left and right sides of the inner furnace lining, providing heating from all four sides. The furnace is of a sealed structure, and the space between the inner furnace and the furnace shell is lined with refractory fiber aluminum silicate cotton and diatomite products as the insulation layer.
5. Determination Procedure: Weigh approximately 3g of the sample that has passed through a sieve with an aperture of about 0.4mm (equivalent to 40 mesh), accurate to 0.1mg, and place it in a porcelain crucible that has been incinerated to constant weight at 500℃ to 550℃ in advance. First, carbonize the sample at low temperature completely, then move it into the furnace and incinerate it at 500℃ to 550℃ for 1 hour. After all is ashed, take it out and cool slightly, then place it in a desiccator to cool to room temperature and weigh. Repeat incineration for 30 minutes, cool to room temperature and weigh, until the weight difference between two consecutive weighings does not exceed 0.0005g.
