The hottest patented two-component insulating glas

Patented two-component insulating glass gluing machine

first of all, let's understand the curing principle of the two-component outer glue of insulating glass

we know that component a of the main rubber of the two-component insulating glass adhesive itself is not cured, and it will be gradually cured only after a certain amount of vulcanizing agent is added. In order to appropriately speed up the curing speed of the adhesive, we add a certain amount of vulcanizing accelerator to the curing agent to speed up the reaction between the vulcanizing agent and the main rubber. When we artificially increase the dosage proportion of the curing agent in order to speed up the curing of the adhesive, Although the vulcanization speed of the rubber is increased, the quality of the rubber itself is reduced. We use a blade to break the accelerated vulcanization and curing rubber and find that the rubber at this time is much softer than the normal rubber, like a foaming sponge. Therefore, in order to ensure the quality of the two-component glue as much as possible, our workers must fully mix it according to the standard proportion to prevent the local accelerator content of the glue from being too high, which will affect the overall quality of the insulating glass

2 the relationship between different vulcanization States and their adhesion during vulcanization of two-component hollow rubber

the raw materials used in the two-component adhesive for insulating glass have strong adhesion, but no matter how strong the adhesion is, the characteristics of the materials need to meet the specific performance requirements, The best adhesion of the two-component adhesive we use (with glass and aluminum strip) is to apply it to the required coating area immediately after adding the specified amount of curing agent, so that it can complete the process from vulcanization to complete vulcanization at the coated area. If we apply the adhesive to the required area in the semi vulcanized state, the bonding strength will be greatly affected

the author has done such an experiment, preparing 200 pieces of glass samples for cleaning and drying, mixing the qualified two-component glue at a time according to the standard proportion, and coating the glue on the sample glass every 10 seconds under the same environmental conditions. When the glue is applied to 116 samples, the glue has lost its bonding ability. After being placed for one day, the bonding force between the glue and the glass is tested respectively, and it is found that the bonding force decreases with the strengthening of the degree of vulcanization, Until the adhesion is completely lost. Recall that in the past, a friend produced insulating glass because of the wrong size, more than 100 pieces of insulating glass were scrapped and put in the open air. Half a year later, it was found that some of them had been cracked and degummed, but some were intact. My friend wondered why the same materials, the same workers, the same production process, the same storage environment, why would there be different sealing effects? The real reason is that there are too many adhesives, which are applied to the glass under different degrees of vulcanization, and the cracked insulating glass is coated with adhesives in the semi curing state

conclusion: in order to achieve the best adhesion of the two-component hollow adhesive, the inorganic insulation materials mainly include rock wool, glass wool, cement foaming insulation materials, etc. must be coated immediately after matching evenly to buffer the strong vibration and impact generated by the passing of high-speed vehicles on the hollow glass, and strive to finish the coating of the adhesive within one minute

3 the function of the two-component glue applicator

the function of the two-component glue applicator is to meet the above three unavoidable defects in manual scraping

first, the proportion is inconsistent

second, the allocation is uneven

third, the glue cannot be applied to the insulating glass immediately after mixing, so that it can complete the process from vulcanization to complete vulcanization on the glass

at the same time, the glue structure applied to the glass edge by the glue applicator under high pressure is dense, The same glue is soft and bubbly when it is mixed manually and applied to the glass. Just like the strong structure of cement concrete after vibration, the concrete without vibration cannot achieve the required strength even if the mixing amount of cement is increased. Therefore, high standard hollow glass, such as curtain wall hollow, must be produced by machine coating

machine gluing is the only way to avoid the four defects of manual scraping at present.

at present, the use of two-component gluing machine in the world must adopt the supporting two-component machine gluing, and machine gluing is actually hand gluing after full grinding and filtration. This kind of glue has good fluidity, fine and greasy without impurities, but this kind of glue has little to do with the sealing performance of the glue itself, just to match the operability of the machine, This is the glue that has undergone fine physical processing (the price is 2 to 3 yuan per kilogram more expensive than manual scraping). It is also common to block the machine when using it. If you use ordinary manual scraping glue and put it in the machine for construction, the machine will not work in less than 10 minutes

glue applicator, as its name suggests, is a machine. The so-called machine is a kind of equipment that can improve the efficiency more than manual production of insulating glass. But the glue applicator on the market can improve the quality of insulating glass, but the improvement of efficiency is not obvious, and a considerable number of equipment are less effective than manual glue scraping. Based on the above reasons

first, the price of glue applied by the supporting machine is expensive

second, the low production efficiency

is the main reason why the majority of insulating glass enterprises do not use it organically.

a new type of insulating glass two-component glue applicator has applied for a national patent in February 2009 (inventor: Zhao Shiping)

this new type of two-component glue applicator overcomes the defects of the glue applicator of the world's well-known technology and has the following special functions

first How to add oil to the universal tensile testing machine when it can normally coat all two-component insulating glass adhesives (including manual scraping):

Second, it can improve the structural strength and compactness of two-component adhesives, so as to greatly improve the overall quality of insulating glass

Third, it is efficient. At present, the working efficiency of two glue applicators with the highest efficiency in the market is that one of this machine can be competent.

if you have such a glue applicator, Then you can use ordinary and cheap manual glue scraping to produce high-grade machine coated insulating glass of 16 to 17 yuan per kilogram, which improves the overall quality and production efficiency of the product. A skilled worker operating the machine can coat insulating glass of more than 800 square meters a day. Smart friends, you should know it. Welcome to visit
