Phenolic foam, máy đổ xốp Phenolic, panel phenolic

Chúng tôi đã bắt đầu triển khai bán các loại máy đổ nhựa phenonlic trên thị trường Việt Nam.

Do đặc tính axit cao, do đó máy đổ xốp Phenolic cần có thiết bị chuyên dụng, từ đường ống, đầu trộn, cho đến bồn chứa đều cần thiết kế đặc biệt để chịu được axit.

Tuy nhiên, lợi thế là nếu sử dụng máy đổ phenolic thì cũng đồng thời sử dụng được nguyên liệu xốp PU trên máy này.

Xốp Phenolic có đặc tính cách nhiệt tốt, hiệu quả chống cháy cao nên được sử dụng nhiều trong các dự án công nghiệp.

PHENOLIC FOAM INJECTOR

 

1.    GENERAL:

PF series of low pressure foaming machine is international high technology products, which combined with the application of china phenolic insulation industry independent innovation to develop high-tech products. The main parts from European famous brand, and the machine performance, safety and reliability is on the advanced level of similar products as Italy made. The equipment reliability and accuracy is on a leading position in china compared other manufacturers.

The PF injector assemble all the module on one rack. And the pipelines is short with less pressure loss, precise temperature control. PF-4 low-pressure foam machines is consisted of phenolic reaction system, and resin Tank A (phenolic liquid), Tank B (curing agent); two measurement units independent motor drived by inverter to change the rotational speed of the metering pump, meanwhile adjusting the material output flow.

Mixing ratio adjustment range: 100:50 to 100:10

2.5 Injection time: 0.5 to 99.99 (accurate to 0.01s)

2.6 The number of injection procedures:

Manual injection: 3 groups operation button / can do continuous injection

2.7 Unit of measurement: measurement accuracy ≤ 0.5%, to make measurement of A/B material. Including: bracket, driving motor, coupling, metering pumps, and electronic pressure switch, etc.

2.8 Pressure limit and control system

The material pressure is at 1 ~ 2MPa. If working pressure exceeds this value, the machine will automatically stop injecting, and alarm with displays a “abnormal working pressure ” fault information.

Electrical protection: When the pressure reaches to the set protection pressure, the equipment will automatically stop and alarm , display “pump overpressure” failure information.

The A pump protection pressure set is 0.25MPa, B is 0.15MPa.

 

2.9 Material flow control and testing unit

As the material mixing ratio requirements, the parameters of A/B material should be set respectively set when injecting; The material flow is adjusted by the rotational speed of the metering pump, then change the proportion of A/B material.

 

2.10 Material filter

The two material all have filter with accuracy of 330μm, to make sure no dust get into material recycling. The filter should be cleaned or changed by sometime to sewage.
