Enamel products are safe, non-toxic and easy to clean with multiple good performance such as high hardness,high temperature resistance, wear resistance and insulation.Therefore,it is used to make bowls,plates,pots,teacups,trays and other appliances.The production of enamel is subject to glaze preparation,embryo preparation,glaze coating,drying,firing and inspection.Due to the need for exterior decoration and use,we usually use a gloss meter to measure the gloss of its appearance.
The quality of enamel products that come into contact with food is of vital importance to the human body.The Chinese national "GB T 13484-2011 contact food enamel products" has a requirement for the appearance gloss of the enamel products for the food.The surface gloss of the shiny device must be greater than or equal to 80 GU and the gloss of the matte ware is usually 50 -60GU.
We know that gloss is generally divided into high gloss,ordinary gloss and low gloss.With 70GU and 10GU as the limit value.Generally,a 60 degree gloss meter can be used to measure the gloss of the enamel surface.When the surface gloss is greater than 70 GU,it is recommended to use a 20 degree gloss meter if you want to improve the resolution.When the surface gloss is less than 10 GU,an 85 degree gloss meter can be used to increase the resolution.
The surface gloss of the enamel material specified by the state must be greater than or equal to 80 GU for light fixtures and 50-60 GU for matte vessels.Therefore,it is recommended to use the Linshang LS191 gloss meter when measuring the enamel surface gloss.The Linshang LS191 gloss meter is a 60 degree gloss meter with a measurement range of 0-200GU.The Linshang gloss meter has the following features:
1.The operation method is simple.The LS191 gloss meter has only one button and the measurement data can be displayed on the interface in real time.
2.With intelligent statistics,the instrument can calculate the maximum, minimum,average values and mean squared difference.The measurement data can be used to judge the uniformity of enamel gloss.
3.The measurement accuracy is high,the Linshang LS191 gloss meter can pass the test of the Chinese national authority measurement institute,in line with the national first-class machine standard.
4.Wide measurement range.The meter can not only measure enamel materials but also measure paint, ceramics, baking varnish and other materials.
The Linshang LS191 gloss meter is stable, compact and can be operated online.It is a good choice for measuring the gloss of materials.For more details, please consult us.Our engineers are devoted to provide the best service.
