How to seal balcony window, how about frameless balcony window?
Many owners of friends choose to seal the balcony when they should use what kind of material, what kind of aluminum alloy window, so let's introduce it to you today. In the industry of frameless balcony window, there is a saying like this: six points of material, three points of technology, and one point of after-sales service
Talk about the material
The main components of frameless balcony windows are: up and down rails; moving glass in the middle; and connecting and pulling their accessories
First of all, track: no matter whether your balcony window is linear or curved with angle, the track material should be aluminum magnesium alloy (industry standard). Magnesium is added to aluminum alloy to strengthen the hardness of profile, The more material the window is made of, the more time it takes to process the rail, the better it will be? If the conditions permit, we still need to find the authoritative department for appraisal. But generally, the most effective way is to cut the window track material. The qualified aluminum magnesium alloy window track has a smooth and glossy cut. The cut surface will not be black and uneven, and there will be no big burr on the edge. The appearance of window track is sprayed with fluorocarbon dust-free (three spraying and three coating). Only by such surface treatment can the profile be more aging resistant, yellowing resistant and smooth. (if the common spraying thickness is not enough, it is easy to fall off, and there are small particles on the surface, and the handle is not good.)
The key to the top ten brands of frameless balcony window lies in the sealing, and the sealing strip plays an important role. The sealing strip material used in the market is generally modified by PVC. In soft PVC, its key role is nothing more than the quality of adding plasticizer. At present, the more stable plasticizers are dioctyl phosphate phthalate and dibutyl ester. But now the market price is very high, some illegal traders use some other cheap things to replace (waste engine oil, the remaining oil base of oil refinery, etc.), which has brought great hidden danger to the majority of consumers.
The product symptoms are as follows:
1. The appearance of oil seeping on the surface appears. Those waste engine oil is not compatible with PVC at all. Grease is easily found on the surface of sealing strip, and yellow marks are also found on the surface of profile. Even not environmental protection, there are many volatile substances, polluting the air.
2. When the so-called plasticizer volatilizes or seeps out, the sealing strip will lose its original softness, become very hard, and will soon age and shrink. As a result, a large gap appears in the airtight part of doors and windows, and the airtightness becomes very poor (water leakage and dust leakage). Especially, the steel lining inside the plastic steel doors and windows will be corroded quickly. Many users often find the pressure from the window inside in rainy season A lot of red liquid flows out of the strip and it is very dirty, that is, the doors and windows are leaking, the steel lining is corroded too early, and the service life of doors and windows will be greatly reduced.
The glass used in frameless balcony window is all toughened. The quality of the glass depends on the quality of the glass. If it is glass produced by small companies or irregular manufacturers, there will be impurities in it, and the transparency is not good. A straight line may become a curve Next it depends on which toughened glass company tempered. Before glass tempering, the manufacturer should cut according to the size of the glass, and then grind the edge. It should be noted here: there are many kinds of glass edging: manual edging has been basically eliminated, but there are still small workshops using mechanical computer edge grinding, but there are two types of edge grinding. The size error of single edge grinding is large, while the probability of dimension error is reduced by double grinding. No frame balcony windows are not encrypted seal, now why add it? In the past, the size error of glass edge grinding was large, which led to the large gap in the middle of glass and poor sealing performance. What's more, the tempering technology of some companies fails to meet the requirements, and the tempered glass is not vertical. So now some companies that do no frame balcony windows will not recommend non encrypted seals to customers, because their materials and technology can not meet the requirements of non encrypted seals. Regular frameless balcony window manufacturers will require the tempering company to mark the trademark, the mark of the tempering company and CCC Mark on each piece of glass they supply, so as to provide customers with the search and inspection. Therefore, I would like to remind you that what the salesman promised to you before signing the bill should be compared one by one after the window is installed to protect their own rights and interests.
