Hollow glass production process several quality control points

Date：2013-11-29 Author：zhaoyang Hits：1073

Various manufacturers in the production process , the focus is inconsistent quality assurance , so there are always some trade-off place. The following process issues often appear just published his own opinion .

Chajiao connection
We used aluminum groove type hollow glass requires double sealed , no matter which path will eventually lead to problems with sealing insulating glass seal failure. The road is sealed with a butyl rubber , the current domestic mechanical process abroad can not guarantee effective seal gusseted junction. Gusseted connection problems , are the remedial measures being taken by the butyl rubber coating --- that work hand- caulking the outside gusseted aluminum .

First, we determine a premise that no matter which path will eventually lead to problems with sealing insulating glass seal failure ; then we put on this by hand butyl rubber caulking aluminum gusseted to do something outside of the evaluation process : advanced production process hand backward links .

And , if you go to the shop look you will find that almost every Chajiao junction blocking butyl rubber filled not enough - that is, most of the gusseted joints sealed or single channel , which will directly lead to a hollow glass seal failure. This part of the workshop on quality control department must have attention, but why would the majority of caulking dissatisfied with it, I think there are two factors : First, the workers are basically basic salary plus piecework , this part of some rough You can save more time ; Second, this process is more cumbersome operation and do not do or make do with less appearance observed .

Bending at the four corners of the aluminum lattice is continuous bending , gusseted joints sealed at basically the same straight line . Reflected in the weaker part of the line connection. Beijing and Shanghai in several glass deep- processing manufacturers I have observed , in-line connections are basically filled the . Why - because the simple and almost no waste of time. Therefore infer , bending aluminum coming widely. But bending aluminum prices are too high, many manufacturers can not accept , and therefore concluded that the development of new products will compete with the emergence of the industry , so that the problem is resolved, the above reminds us : attention to sealing gusseted junction , caulking sufficient .

Molecular sieve adsorption time
Even if all of the materials you have used hollow glass best , your product may still not passed the test. The material has its own characteristics, such as molecular sieves.

Full sieve adsorption time per 24 hours is inspected . Even better production process , we use molecular sieves have a basic exposure time requirements: from starting until you open the bag filled insulating glass sealant filling finished second , longer than 4 hours. If you have higher requirements for insulating glass, exposure time can be shortened to 1. 5 hours . Exposure time as short as possible , but less than 1. 5 hours of the production process is more difficult to operate in mass production .

Some companies strict quality assurance . One morning I went to a glass factory production workshop , not the time to go to work , I saw a pile of plastic pots inside the zeolite Banpen , about 5 kg by the end of 2005 - the so products can support a summer and a winter too you ! . I told them truthfully speaking boss consequences , and later to the time or so , tell no one cares . Later, I interrupted and their business.

Polysulfide rubber curing time
First, the curing time can not be adjusted , the curing time is too long workshop may not have enough space to place ; too short , then the cure speed is too fast , not enough time for the coating , the more serious is the cause of the cured polysulfide reduce the adhesive performance , within a specific time to grasp the scope of the manufacturers should be given .

Second, part of which can determine the quality of polysulfide rubber - construction performance . For example, the Central Plains polysulfide rubber , his A, B component is using the ratio 100:7 ~ 100:14 , while the proportion of many manufacturers are given : 10:1 , you know, this is only a theoretical value , the actual operation is not possible , it has also become a part of the manufacturers of quality irresponsible excuse.

Drying speed and new finished insulating glass mist .
Last month, in a hollow glass, to see just produced hollow glass placed under the hot sun , and soon out of the mist, we were surprised , suspicion quality and craftsmanship of hollow glass materials.

This phenomenon can be explained by the drying rate of hollow glass. As we all know , there is a molecular sieve adsorption process steam . Molecular sieve adsorption rate slower the better . Molecular sieve adsorption is only partially completed , the static air inside the hollow glass also contains more water vapor , so the mist phenomenon occurred. Wait sieve to complete the task , fog disappears naturally.

Several factors influence the drying rate of the hollow glass are: production workshop air humidity , the filling ratio zeolite , molecular sieve adsorption rate , pore size and aluminum density of sealing quality , the above phenomenon is seen in the analysis only . Of his own view, multi- industry friends hope to enlighten.
