# Simplified Quality Assurance Points for Fly Ash Brick Making Machine Production Product quality requires **full-process control over raw materials, equipment, processes, and testing**. The core measures are as follows:

I. Raw Material Control: Source Quality Check
1. **Qualified Raw Materials** Fly ash must meet GB/T 1596-2017 (fineness ≤30%, loss on ignition ≤8%); use P.O 42.5 grade cement, lime with CaO ≥80%, gypsum ≥90%, and clean water.
2. **Precise Proportioning** Adopt an automatic batching system (error within ±1%), mix materials according to the formula (fly ash 30%-70%, etc.), and adjust water content based on raw material humidity (10%-15% for dry mixes, 20%-25% for slurries).

II. Equipment Guarantee: Stability & Precision
1. **Molding Equipment** Hydraulic machines: pressure 10-30MPa (≥20MPa for load-bearing bricks); vibration machines: frequency 2,000-3,000 times/min. Regularly calibrate molds (error ≤0.1mm) and ensure uniform material distribution.
2. **Curing Equipment** Steam curing kilns: control temperature (heat up to 60-90℃, keep constant for 4-6h) and humidity ≥90%; for natural curing, avoid direct sunlight/rain, and maintain temperature ≥5℃ in low-temperature conditions.

III. Process Standardization: Proper Operation
1. **Mixing** Use a dual-shaft mixer for 3-8 minutes; complete molding within 30 minutes to avoid raw material agglomeration/premature setting.
2. **Molding** Cycle time: 15-30 seconds; slow demolding (≤50mm/s) and use release agent to prevent adhesion.
3. **Curing** Steam-cure load-bearing bricks for 3-5 days; naturally cure non-load-bearing bricks for 7-14 days. Stack cured bricks ≤1.5 meters high. 

IV. Testing Check: Eliminate Defective Products
1. **In-Process Testing** Sample every 100 molds to check green brick dimensions (deviation ≤±2mm) and appearance; test strength in the middle of curing (reach over 70% of the design value).
2. **Finished Product Testing** Batch-by-batch inspect compressive strength (MU10 ≥10MPa, etc.), water absorption ≤18%, and frost resistance (no damage after 25 cycles). Destroy defective products.
