Temizlenmemiş sert cam yıkama nedenleri

Temizlenmemiş sert cam yıkama nedenleri

In daily life, we often contact toughened glass products, such as tea tables, tempered glass doors, tempered bathroom doors and so on. When cleaning such objects, we will find that some toughened glass is not clean. What causes the washing of glass is not clean? Tempered glass is not clean because the quality of glass is not up to standard.After tempering, there are defects such as glass bars and pock marks.

Whether the quality of toughened glass can meet the standard, besides the reason of glass raw material, whether the setting of technological parameters is reasonable is the decisive factor. Only by thoroughly understanding the relationship between their functions and relations can they produce high quality tempered glass. All the parameters are designed around theuniform heating and rapid cooling”, but they are not isolated, but also an organic whole.We must consider comprehensively to get a perfect process. Temperature related glass defects and correction methods:

  1. Wave bars
    If the temperature is too high and the heating time is too long, the waves will appear in the glass. This is because the heating of the glass has exceeded the critical point, and the glass has begun to soften. If there is such a defect, the heating time will be shortened.
  2. Pock marks
    Too long heating time will also cause pitting on the lower surface of the glass. There are two kinds of pockmarks, one is concentrated and orange peel, çok uzun ısıtma süresinden kaynaklanır, özellikle kalınlığı fazla olan kalın camlar için 12 milimetre. Bazı üniteler, kesintisiz hale getirmek için ısıtma süresini uzun süre ayarlayabilir, Bu duruma göre ayarlanabilir.Yukarıdaki üst kademenin ve seramik silindirin yüzeyinin temiz olmaması nedeniyle, veya ön cam silindiri tablasının cam parçalarının temizlenmediği.

3, beyaz sis
Beyaz sis, camın alt yüzeyinin ortasında beyaz bir işarettir. Genellikle ilk birkaç ocakta görülür. Seramik merdanenin aşırı yüzey sıcaklığından kaynaklanır. Cam fırına birkaç on saniye girdiğinde, camın alt yüzeyi ısı iletiminden doğrudan etkilenir, ve dört köşe kıvrılıyor, cam ve seramik rulo arasındaki temas yüzeyi küçülür, ve seramik silindirin sürtünme kuvveti artar Seramik silindirin yüzey sıcaklığının düşmesi ile kaybolur. İlk üretimde düşük sıcaklığı ayarlayabiliriz, düşük gücü düşürmek, ve fırının sürekli üretildiğinden emin olun, böylece fırın havaya kaldırılamaz. Üretim geçici olarak durdurulursa, ısıtma anahtarı kapatılabilir ve beyaz sis önlenir.

4, bükme
Sertleştirilmiş cam ürettiğimizde, bükme genellikle rüzgar basıncını ayarlayarak veya üfleme mesafesini ayarlayarak yapılır. Çok verimli ve hızlı. ancak, some operators do not understand that the difference in temperature between the upper and lower will also cause the bending of the glass. Assuming that the distance between the windscreen segments and the wind pressure is the same, if the four corners of the glass are bent upward, it will indicate that the temperature of the lower part is too low.On the contrary, if the four corners of the glass are bent down, it means that the temperature at the bottom is too high. If the temperature needs to be adjusted to make the glass level, it will not be solved by the one or two furnace.

5, sphere
This is done when the thin glass is below 6 mm and the layout is bigger. It can be adjusted by the function of temperature adjustment. The temperature of the middle and the upper and lower parts of the middle can be adjusted up. Sometimes it needs to be adjusted about 30 derece. (from the second rows on the vertical side to the middle), an excellent operator should understand that the relationship between temperature and optical performance is: the temperature is high, the heating time is long, and the yield is high.But the optical performance will be poor. Otherwise, the temperature is low or the heating time is short, the optical performance is good, but the yield will be low. This requires us to sum up carefully and find the best effect. The temperature is highly related to the granularity of tempered glass. Under the condition of equal wind pressure, the temperature is high, the particles are small, the temperature is low and the particles are large.
