The traditional baking-free brick can divided two sorts. One is pressure molding clay baking-free brick, the other one is Baking-free brick forming waste residue.
a.Pressure molding clay baking-free brick:
Using clay as the main raw material,adding a small amount of gelled material,It is a kind of non fired common clay brick by force on smash, mix, compression molding and nature curing.
As material of general housing Building wall, the shape is rectangle, the gauge is 240mm*115mm*53mm.
Through compared size deviation, outwards quality and strength with building materials industry standard JC422-91 to divide first class product andconformity product.According to strength can divide 3 degree: level 7.5, level 10 and level 15.
b.Baking-free brick forming waste residue:
It is load-bearing brick or load bearing hollow brick which adopt use industrial waste as the main raw material.Which use a small amount cement as cementing material. Which add lime, plaster, and additive at the same time. Which through stir when add water in preparing semi dry materials, increase pressure or vibratory compaction and then nature curing[ or autoclaved curing].
This is the traditional baking-free brick.
The baking-free block centered on strength and durability.In simple terms,The strength and durability of baking-free brick mainly comes from two aspectsin simple terms:a.The physical function of molding machine
b.The chemistry function after forming gelled material or adhesive material chemistry
Physical function:Different effect power can make principle baking-free block more intense and more durable .It including the pressure of machine、vibration power、and vacuum forming the vacuum force when pouring shape at the time of the casting . In addition,and wheel grinding, mixing of materials produced by the homogenization, plasticizing and other auxiliary forces.It can divided two sorts.
1.The power of a single.As only pressure power or only vibration power.
2.The strength of composite.For example,it can not only use pressure power,but also use vibration power and vacuum power.
Chemistry function:In general,it is depend rely on cementing material,such as cementing force of cement, magnesite, gypsum ,combine other material particles into a whole .But it can divided flush chemistry intention,mediate chemistry intention and composite chemistry intention.
1.flush chemistry intention. It refers to flush use cementing combine different material.Cementitious materials including method for Cementation of making cement, gypsum, or adhesion of phenolic resin, unsaturated polyester. It is effective for the majority of solid waste materials.And is the widely used in the baking-free brick molding.
2.Mediate chemistry intention. It is exploit excitation function by stimulating effects on activity of solid wastes, to make active solid wastes to produce gelproperties, and then combine different material.
3.Composite chemistry intention. It is combine flush chemistry intention and mediate chemistry.
However, in real life ,Most are the physical effects of the combined with chemical method .It is depend on actual situation of waste and requirements of unburned brick technology about what is the role in the physical or chemical action.
We has long committed to aerated autoclaved concrete block machine and baking-free block machine research,has always been leading China’s baking-free brick machine and aerated autoclaved concrete block machine of development, the company motto of ”keep improving, quality outstanding” the goal, try to meet customer demand, won unanimous favorable comment of customer, product reputation at home and abroad. In order to give new and old customer better service, dongyue engineers summarize the using brick machine nine skills, help you do safety and quality production.
1 in the process of production, and the oil pump motor running sweaty can lead to motor burned down, the reason is the total pressure of valve equipment is too much. Should turn govern valve down, until the motor run normal Be a timely adjust and check is the operation condition of machine
2, hollow brick machine electric power system of power host line select 2 above 25 ㎜ aluminum wire or 16 ㎜ copper wire.when Equipment is under the normal operation ,the input voltage is high voltage 380 V-410 V, low voltage 330 V-360 V, the machine must have reliable grounding
3, when the new vibration is insufficient, the brick forming cycle is long or a loose brick can appear ,beacuse the down mould pressure dowm too much, the pressure inhibit the vibrating, should turn down the pressure valve .
4, cause mould, balance arms and host block machine parts appear open welding or damage, because the pressure of the down mould turn too low, the pressure can not lock the down mold, leading to a fully conscious of excessive vibration, which affects the whole equipment parts, should governing valve pressure builds up, to stabilize the vibrating force machine.
5, when a brick face loose, break off , or when the upper mould with down mould die move up, the reason is the pressure of the pressure head is too little: can’t make brick position leading to loose.
6,the middle of brick occurrence,because the stress of hydraulic is too big , or vibration time is too short, the uppermould can not pressure in the place.
7 if governing valve fail, because the governing valve spring inside is damaged, should replace the spring.
8,if a cylinder leak oil, the reason is the cylinder of seal sealing the result is bad, should change in time the corresponding types of sealing parts.
9, concrete hollow brick machine operation shall read product manual carefully before production, each operating person should be comprehensive trained, until assessment qualified is good.
