Model NO.: YQ-Z-48B
Origin: China (Mainland)
Paper Brightness Meter Testing Equipment Cardboard Whiteness Tester

1. Description:
This brightness meter is mainly used to measure the whiteness of paper, paperboard, paper pulps, pulps of chemical fiber, cotton, chemical fiber, textile, plastic, starch, salt, white cement, porcelain clay and talcum powder, etc. It can also be used to measure the opacity and other optical performance of thin pages.
1.1 Measure the diffuse blue reflectance factor (R457), which is also called "blue brightness" or "ISO brightness".
1.2 Analyze whether the sample material contains fluorescence brightener, and measure the fluorescence brightness produced from fluorescence emission. I. E. Brightness degree.
1.3 Measure the brightness stimulus value Y10 of sample, I. E. Diffuse green reflectance factor Ry.
1.4 Measure the transparency, opacity, optical-absorption coefficient and light-scattering coefficient of samples.
1.5 Measure the ink absorbency of paper and board.

Graphite Mould

At our factory outlet, we offer a wide range of hot-selling graphite moulds for casting. These moulds are manufactured using high-quality graphite materials, ensuring durability and long-lasting performance. Our graphite moulds are designed to withstand high temperatures and provide excellent dimensional accuracy for producing high-quality castings.


Some of our popular graphite moulds for casting include:


1. Graphite Ingot Moulds: These moulds are used for casting metal ingots, such as gold, silver, and other precious metals. They come in various sizes and shapes to accommodate different casting requirements.


2. Graphite Crucibles: Crucibles are essential for melting and pouring molten metal into moulds. Our graphite crucibles are highly resistant to thermal shock and have excellent heat retention properties.


3. Graphite Dies: Dies are used for casting complex shapes and intricate parts. Our graphite dies are precision-machined to ensure accurate and repeatable casting results.


4. Graphite Plates: Plates are used for casting flat or thin metal parts. Our graphite plates are available in various thicknesses and sizes to meet different casting needs.


5. Graphite Rings: Rings are commonly used for casting cylindrical or round-shaped metal parts. Our graphite rings are highly durable and can withstand high temperatures and pressures.


All our graphite moulds are carefully crafted to meet the highest quality standards. They undergo rigorous quality checks to ensure they are free from defects and can provide consistent and reliable casting results.


If you are looking for high-quality graphite moulds for casting, visit our factory outlet to explore our wide range of hot-selling products. Our knowledgeable staff will assist you in finding the right moulds for your specific casting requirements.
