Tightness is an important goal of glass bottles, especially for bottles containing food. If air leaks, it will cause erosion and transformation of food, which is harmful to human health, so how to detect the air tightness of glass bottles? , Glass bottle.　　1. Investigate whether there are oblique caps, tilted caps, sliding caps and crushed claws in the glass bottle caps.　　2, investigate whether the cover surface is concave, whether the safety button is sunken, to confirm whether there is a vacuum in the glass bottle. 3. Measure the glass bottle manufacturer when tightening the azimuth measurement, first find out the straight seam of the bottleneck on the bottle mouth of the glass bottle, use a ruler to measure the distance between the bottleneck of the glass bottle and the starting edge of the closest lid claw, which is the tightening azimuth. , The measured value is taken from the right side of the straight seam of the bottleneck of the glass bottle as a positive value for the wine bottle, and the value taken from the left side of the bottleneck of the glass bottle is a negative value. Why can't the glass bottle be filled too slowly? Friends may have encountered the situation that the bottle suddenly burst without external force. This is caused by the internal squeezing force. The reason for the bottle manufacturer is that the liquid contained When it is full, the glass bottle cannot withstand this force. The reason why the bottle breaks and the bottle cap bursts out and hurts people. This is because the liquor, wine and honey contain glucose. The customized glass bottle will produce hydrogen peroxide under the action of glucose oxidase. The hydrogen peroxide is at high temperature. Oxygen is easily decomposed, resulting in more air in the bottle. If the honey bottle or white wine bottle is too full, it will cause the bottle to swell and deform.
