4 PRIMARY STEPS OF BRICK MANUFACTURING PROCESS
|砖制造涉及的步骤
砖的制造包括以下四个操作或步骤。
- 制备砖粘土或砖土
- Moulding of bricks
- Air drying of bricks
- Burning of bricks
1。制备砖粘土或砖土
在此步骤中,将土壤以台阶进行挖掘,然后放在平稳的地面上。然后,将土壤清洗为植被,石头或卵石等杂质。去除杂质后,它会暴露于天气几个月。这称为风化过程。在完成风化过程后,将土壤与其他材料混合在一起,以准备好砖土。然后,通过彻底破坏,浇水并揉捏混合土壤。调速通常是在哈巴狗磨坊中进行的。
2。Moulding of Bricks
根据要生产的产品质量,砖块以多种方式模制。通常,成型是通过以下两种方式完成的
- 手工成型
- 机器成型
对于手工成型,钢化粘土被强迫在模具中,以使其填满模具的所有角落。通过木制罢工或用电线框架去除额外的粘土。然后将模具抬起,然后将生砖放在地面上。
在要制造大量砖块的情况下,使用机器成型。用于成型的机器通常有两种类型。
- 塑料粘土机
- 干粘土机
In plastic clay machine the clay in plastic state is forced to rectangular openings of a size equal to the length and breadth of the bricks and are then cut into strips of thickness of the brick with wires in frames.
In dry clay machines, dry clay is reduced to powder, filled dry into mould by the machine and then are subjected to high pressure to form hard and well shaped bricks.
3。Drying of Bricks
干燥通常是通过将砖块放在带有开放侧面的棚子中来完成的,以确保空气的自由循环并防止恶劣的天气和雨水。允许砖块干燥,直到将水分含量为5%到7%。干燥期通常从7到14天不等。由于以下原因,模制砖被干燥。
- 如果直接将湿砖或绿砖直接燃烧,则可能会破裂并扭曲
- 要清除砖中的最大水分,以节省燃烧期间的时间和燃料
- 为了提高生砖的强度,以便可以在窑炉中处理和堆叠更高的高度,以燃烧而不会损坏。
4。burn
这是制造砖的非常重要的一步。砖可以通过下面给出的两种不同的方法燃烧。
- 燃烧在夹具或帕萨瓦(Pazawah)中被称为clamp burning
- 在火焰窑或巴塔中燃烧窑炉燃烧
在夹子,一批绿色砖堆氧化铝ng with firewood, coal etc. and sealed with clay. It is then fired slowly to intense heat which may take many days. Modern kilns, however, permanent structures consisting of many chambers. There areintermittent and continuous kilns。模制粘土被堆叠在房间中。然后将它们缓慢干燥并燃烧至高温并冷却。装载,干燥,燃烧,冷却和排空的一个周期可能需要多达两周的时间。这些过程是在间歇性的窑炉中间歇性地进行的,并在连续的窑中以循环顺序进行。
Is there any other soil apart from clay can be good for brick making?
为什么挖掘过程后的粘土量仅限于600mm至1200mm(我在大多数书籍上都发现)?背后有工程吗?
Why the bricks are burnt?
In order to attain hardness, strength and weather resistant properties. Green bricks are not able to resist load to a great extent moreover they get damaged when water comes in there contact. Once the bricks are fired the alumina and silica present in the brick earth fuse together hence changing the chemical as well as physical properties of the green bricks.
Yes
烤箱干燥仅需24 - 48小时
黑棉土用来制造砖块?
Which type of bricks not dried?
Moulded bricks
drying bricks takes along time of 7-14 days ,is their any other short form than that
为什么粘土砖被燃烧
然后只有它具有稳定性和抗压强度
