The production process of fireproof material involves a few step, the option that includes raw material, mix, shape, dry, fire and finish machining. It is the detailed overview of every measure below:
The choice of 1. raw material is fireproof material by natural and mineral with synthesis material is made. The choice depends on wants property and application. Common raw material includes: Alumina zircon of dolomite of chromite of bauxite of magnesite of 2 oxidation silicon
The preparative raw material of 2. raw material carries a series of craft preparation: Smash and abrade: Raw material is smashed and grind wear fine pink, in order to achieve a needed particle size distribution. Screening and classification: Undertake to powder screening is mixed classification, in order to ensure the uniformity of finished product and consistency.
3. mixes raw material and adhesive, additive and water, form even mixture. Composition depends on the specific type of the fireproof material of a production. Mix can undertake in the blender of all sorts of types, for example: Collect of secret of agitate of disk type of paddle type mixer blender
4. shapes to form mixture material wants form next. According to the type of fireproof material product, use all sorts of shaping technology: Suppress: Hydraulic pressure or mechanical compressor are used at shaping below high pressure brick and other form. Extruding: Material squashs to manage shape and good account through the mould. Mould: Pour mixture into the mould, form whole fireproof material or pouring makings. Note model to shape: Use at complex form and fine detail.
5. is dry the moisture content that shaping fireproof material product contains need purify. Dry undertake below controlled condition, in order to prevent craze and warp: Air is dry: Undertake below ambient conditions initiative and dry. Control is dry: Use kiln or kiln control temperature and humidity carefully.
6. agglomeration fire is to gift the crucial step of fireproof data strength and wear. It is involved heat in kiln or product of furnace lieutenant general high temperature, in order to cause chemistry and physical change: Agglomeration: Heat material slightly under its melting point, make grain is united in wedlock together. To calcine: The water that purify chemistry combines and other volatile material.
The fireproof material of frit of report of 7. cut nap, be like brick of founding zirconium corundum, after heat preservation is passed after founding, still need to have precision work, in order to reach a needed measure and exterior mass: Cut and abrade: Implement the appearance of composite level and measure. Exterior coating: Bring to bear on coating in order to offer additional protection or enhance specific performance.
8. quality control is in whole production process, carry out strict quality to control measure, in order to ensure the product accords with the standard of the requirement and standard: Physics checks: Measure rate of density, hole, intensity and coefficient of thermal conductivity. Chemical analysis: Check chemical class status in order to ensure consistency. Dimension examination: Ensure the product accords with formulary dimension and public errand.
9. is packed and carry finished product fireproof material course is packed carefully, be being carried in order to prevent and store the attaint in the process. Proper label and file are crucial also to dogging to assure with quality.
The production process that summarizes fireproof data is complex, involve many step, in order to ensure the product has high temperature and the property that slashing application wants. The choice of raw material, mix and shape the quality control in the process, careful dry be being controlled with fire and strict quality is manufacturing high quality the key of fireproof material.
