Have a deeper understanding of laundry gel beads
The self-degree of the laundry beads is the apparent characteristic of the laundry beads, which refers to the ratio of the surface of the laundry beads to the diffuse reflection radiant energy of the fully reflective diffusion surface in the visible light region, that is, the degree of whiteness is called BaiDu. The whiteness meter was irradiated with D65 light source. After the whiteness meter was calibrated with a standard whiteboard, the tristimulus values u200bu200bX, Y, and Z of the sample were measured, and the whiteness was calculated by the Ganz whiteness formula.
① For the convenience of measurement, a white porcelain plate with a flat surface, no nicks, and no cracks can be used as the working whiteboard for daily whiteness measurement. The working whiteboard should be calibrated with a standard whiteboard.
② The working whiteboard should be stored in a desiccator in a dark place. If it is polluted, it must be wiped with a flannel or absorbent cotton dipped in absolute ethanol. Then put it in a drying oven at 105-110°C for 30 minutes, take it out, and cool it to room temperature in a desiccator. Use standard self-board calibration.
The main material of laundry gel beads is bleaching agent: such as sodium perborate, sodium percarbonate and other peroxides. Bleached laundry beads mainly add sodium percarbonate. This is because the laundry gel is at 60. Hot water above C can release active oxygen during washing, which can bleach stains on fabrics and clothes. White clothes can be washed whiter, but it is better not to wash colored clothes at high temperatures, as this will bleach the colored parts and make the clothes old.
