How to make foam for foam machine
The following points shall be met during the production of sponge:
1. Proportioning of large materials
Formulate according to the work order of the day (such as the variety to be produced). The materials (such as polyether, polymer and talcum powder) shall be prepared by the operator in charge according to the percentage in the formula Finally, pump the raw materials into the cylinder body with agitation, and adjust the temperature of the large cylinder used for pumping foam after about 50 minutes of agitation.
2. Check and pump TDI
Check whether the TDI in the TDI container is enough to compare with that used in the formula. If it is not enough, you should wear a mask and rubber gloves
In the case of TDI, pull the TDI from the raw material warehouse to the place where it is used and pump it into the cylinder body with agitation. When adjusting the temperature, pay special attention to prevent TDI from splashing on the skin and eyes from the barrel, if any, wash it with clean water or seek medical advice in time.
3. Proportioning of small materials
Prepare small materials in percentage, such as T-9, A33 and silicone oil The ingredients prepared from the color material shall be poured into the corresponding iron container for stirring for foaming. During this operation, the operator shall have a good sense of protection and wear a mask and rubber gloves.
4. Check and debug the machine
After studying all the preparations, the operator shall repeatedly check each switch and button during the commissioning of the foaming machine. The machine can be started only after it is accurate.
5. Startup process
The machine can be started after the work is fully prepared and the personnel at each post are in place. A large amount of gas is discharged during the formation of sponge. The gas is discharged to the outside by the exhaust fan. The operator should wear a mask and rubber gloves prepared in advance for operation.
Sponge is a kind of light industrial product formed by the high-speed operation of the foaming machine head and the final chemical reaction based on the proportion of raw materials and the flow test.
