**Principle and comparison of high-pressure foaming and low-pressure foaming of polyurethane**

1. Low-Pressure Foaming
Principle:
Mechanical mixing: Mix material A (isocyanate) and material B (polyol + additives) by low-speed stirring (200-1000 rpm), and inject them into the mold by gravity or low pressure.
Chemical reaction: Isocyanate (-NCO) reacts with polyol (-OH) to form polyurethane, accompanied by the formation of CO₂ bubbles (foaming agent effect).
Jellemzők:
– The mixing accuracy is low, and problems such as uneven bubbles and inconsistent density are prone to occur.

2. High-Pressure Foaming
Principle:
High-pressure impact mixing: A and B materials are accurately measured under high pressure (100-200 bar) and instantly mixed (mixing time <1ms) by high-precision collision mixing heads.
-Atomization mixing: High pressure makes the raw materials atomized to ensure uniform mixing at the molecular level.

Core advantages of high-pressure foaming:
1. More uniform mixing and finer pores
– High-pressure atomization can reduce dead zones and avoid defects caused by unmixed materials (such as lumps and uneven bubbles).
2. Higher production efficiency
– Suitable for automated continuous production.
3. Less material waste
– The mixing head is self-cleaning, with a residual amount of <0.1%, which reduces raw material loss and can save 7-9% of raw materials compared to low-pressure foaming.
4. Better product performance
– The pore structure is more uniform.

High-pressure foaming technology is superior to low-pressure foaming in terms of mixing accuracy, production efficiency and product performance, and is particularly suitable for high-end manufacturing.

1 készlet pu host gép

A PU főkeret hossza általában 25-30 méter, amelyet a megrendelő által megadott rajzok és a kívánt habvastagság határoz meg. Az ügyfelek termelési igényeinek jobb kielégítése érdekében a berendezés tervezésekor teljes mértékben figyelembe vették a különböző termékspecifikációk sokféleségét és rugalmasságát, így a berendezés a különböző termelési forgatókönyvekhez alkalmazkodik.

A főkeretünk gumihevederes erőátviteli rendszert alkalmaz, amely nemcsak a berendezés stabilitását és hatékonyságát biztosítja működés közben, hanem jelentősen csökkenti a gép gyártási költségeit is. A hagyományos erőátviteli módszerekkel összehasonlítva a gumihevederek kiváló ütéselnyelő és kopásállóságúak, ezáltal meghosszabbítják a berendezés élettartamát, csökkentik a karbantartási gyakoriságot, és megtakarítják a vállalkozások későbbi üzemeltetési költségeit.

1 PLC vezérlőrendszer teljes készlete

Az egész főgép 3 részből áll: tekercselőgép, PU habosító rendszer és nyírórendszer. Mindegyik rész független elektronikus vezérlőrendszerrel rendelkezik, és a 3 rendszer intelligens módon online működtethető.
