**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).
Особенности:
– 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.

Длина полиуретановой рамы обычно составляет от 25 до 30 метров, что определяется чертежами, предоставленными заказчиком, и требуемой толщиной вспенивания. Чтобы лучше удовлетворить производственные потребности клиентов, оборудование разработано с учетом разнообразия и гибкости различных спецификаций продукции, чтобы оно могло адаптироваться к различным сценариям производства.

В нашей главной раме используется система передачи на резиновых ремнях, которая не только обеспечивает стабильность и эффективность оборудования во время работы, но и значительно снижает стоимость производства машины. По сравнению с традиционными методами передачи, резиновые ремни обладают отличной амортизацией и износостойкостью, что продлевает срок службы оборудования, снижает частоту технического обслуживания и экономит последующие эксплуатационные расходы предприятий.

1 Полный комплект системы управления PLC

Вся основная машина состоит из 3 частей: валковой машины, системы вспенивания полиуретана и системы стрижки. Каждая часть имеет независимую электронную систему управления, и все три системы могут управляться интеллектуально в режиме онлайн.
