Problems solved by technology

After tempering, some nickel sulfide stones will change in crystal state with time and environmental changes, resulting in an increase in volume, causing micro-cracks inside the glass, which may lead to self-explosion of the glass
[0004] After the self-explosion, a...

Embodiment 1

[0025] A method for preparing antifouling tempered glass for household use, comprising the following steps:

[0026] Step 1, ingredients: take quartz sand, limestone, aluminum alum, sodium hydroxide, Glauber's salt, feldspar, molybdenum trioxide, carbon powder, clarifying agent and cadmium oxide according to the ratio of parts by mass;

[0027] Step 2, Grinding, drying and mixing: Grind quartz sand, limestone, bauxite, sodium hydroxide, Glauber’s salt, feldspar, carbon powder and clarifying agent to 400-600 μm, dry the powder after grinding, and control the moisture at 2.8%; put the dried raw materials into a mixer and mix for 1.5min to obtain component A, and set aside; then add 30 times of molybdenum trioxide and cadmium oxide to dissolve in water, use wet grinding, spray dry after concentration, Carry out dry grinding again, dry, pass through 800 mesh sieve, moisture content is controlled at 0.75%, obtain component B; then component B is added in the mixer and mixed with co...

Embodiment 2

[0042] A method for preparing antifouling tempered glass for household use, comprising the following steps:

[0043] Step 1, ingredients: take quartz sand, limestone, aluminum alum, sodium hydroxide, Glauber's salt, feldspar, molybdenum trioxide, carbon powder, clarifying agent and cadmium oxide according to the ratio of parts by mass;

Abstract

The invention discloses a preparation method of household antifouling tempered glass. The method comprises the following steps: in the tempered glass cooling process, intermittently blowing to lower the glass temperature to 470-490 DEG C; then, carrying out ultrasonic cleaning on the glass, continuously blowing air and drying, and reducing the temperature of the glass to 150-180 DEG C; and respectively carrying out antifouling treatment on the two sides of the glass by adopting an antifouling coating, and finally cooling to room temperature by cold air. According to the method, ultrasonic cleaning is conducted on the glass after intermittent air blowing is conducted on the glass, and then antifouling treatment is conducted at the temperature of 150-180 DEG C, so that energy can be saved, and antifouling treatment is directly conducted at the temperature; and due to the fact that the main components of the antifouling coating are hydroxyl polyester resin and carboxyl-terminated polyester resin, a compact film structure can be formed, so that the protection effect on the glass is better, even if the glass bursts, the probability of splashing of glass fragments is lower, and the household use is safer.

Description

technical field [0001] The invention relates to the technical field of tempered glass, in particular to a preparation method of antifouling tempered glass for household use. Background technique [0002] Tempered glass (Tempered glass / Reinforced glass) belongs to safety glass. Tempered glass is actually a kind of prestressed glass. In order to improve the strength of glass, chemical or physical methods are usually used to form compressive stress on the glass surface. Wind pressure, cold and heat, impact, etc. [0003] For the production of tempered glass, the most likely problem is the phenomenon of self-explosion, that is, the phenomenon of self-rupture without the action of external mechanical force. The self-explosion of tempered glass can be called the "cancer" of the glass industry. At present, there is no way to solve this problem. a question. There are various reasons for the self-explosion of tempered glass. The main reason is that there are heterogeneous particle...
