**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).
Özellikler:
– 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 set pu ana makine

PU ana şasinin uzunluğu genellikle 25 ila 30 metredir ve bu uzunluk müşteri tarafından sağlanan çizimler ve gerekli köpük kalınlığı ile belirlenir. Müşterilerin üretim ihtiyaçlarını daha iyi karşılamak için ekipman, çeşitli üretim senaryolarına uyum sağlayabilmesi için farklı ürün özelliklerinin çeşitliliği ve esnekliği tamamen göz önünde bulundurularak tasarlanmıştır.

Ana şasimiz, yalnızca çalışma sırasında ekipmanın dengesini ve verimliliğini sağlamakla kalmayan, aynı zamanda makinenin üretim maliyetini de önemli ölçüde azaltan bir kauçuk kayış iletim sistemi kullanır. Geleneksel iletim yöntemleriyle karşılaştırıldığında, kauçuk kayışlar şok emilimi ve aşınma direnci açısından mükemmeldir, böylece ekipmanın hizmet ömrünü uzatır, bakım sıklığını azaltır ve işletmeler için sonraki işletme maliyetlerinden tasarruf sağlar.

1 Tüm PLC Kontrol Sistemi seti

Tüm ana makine 3 parçadan oluşur: rulo şekillendirme makinesi, PU köpük sistemi ve kesme sistemi. Her parçanın bağımsız bir elektronik kontrol sistemi vardır ve 3 sistem akıllı bir şekilde çevrimiçi olarak çalıştırılabilir.
