1. The adhesive layer has strong weather resistance. PUR reactive hot melt adhesive can undergo physical and chemical covalent bond reactions with the surface of the substrate, thus forming a physically riveted whole between the two substrates, which will not break under certain temperature conditions. Therefore, its overall bonding strength will not change with seasonal temperature differences. 2. PUR hot melt adhesive is solid in itself, but after heating, it becomes liquid and has good fluidity, allowing it to automatically flow into gaps between objects, solving component tolerances and avoiding weak adhesion issues. 3. The transition from liquid to solid results in high initial adhesion. The adhesive layer after thermal reaction has high bonding strength, can withstand high and low temperatures, high humidity, has good weather resistance, and a long service life. 4. PUR hot melt adhesive possesses the characteristics of ordinary hot melt adhesives, meeting the initial rapid curing assembly requirements for object bonding and better achieving different process assembly and industrial automation production requirements.
With the increasing emphasis on environmental protection and consumers' demands for indoor air quality in home life,hot melt adhesive hasthe characteristic of rapid curing and is widely used as an environmentally friendly adhesive material inthe home appliance and furniture industry. For example, it is used for bonding components of products such as 3D mattresses, sofas, refrigerators, air conditioners, televisions, computers, mobile phones, speakers, and fabrics for clothing.
First of all, what is PUR hot melt adhesive?
1. The adhesive layer has strong weather resistance. PUR reactive hot melt adhesive can undergo physical and chemical covalent bond reactions with the surface of the substrate, forming a physical riveted whole between the two substrates that will not break under certain temperature conditions. Therefore, its overall bonding strength will not change with seasonal temperature differences.
2. PUR hot melt adhesive is solid at room temperature but becomes liquid when heated. It has good fluidity and can automatically flow into gaps between objects to solve component tolerances and avoid weak adhesion issues.
3. The transition from liquid to solid results in high initial adhesion strength. The adhesive layer after thermal reaction has high bonding strength and can withstand high and low temperatures as well as high humidity; it has good weather resistance and a long service life.
4. PUR hot melt adhesive possesses the characteristics of ordinary hot melt adhesives, meeting the initial rapid curing assembly requirements for object bonding while better achieving different process assembly and industrial automation production requirements.
Next, what isPUR hot melt adhesive machine?
The spraying technology of hot melt adhesive machines mainly utilizes high temperatures to melt solid hot melt adhesives into liquid form. With pressure devices and program control systems, the melted glue is transmitted through hot melt glue pipes or guns for automatic spraying onto substrates. After cooling down, the bonding is completed. It integrates heating control, pressure devices, liquid delivery functions for gluing applications such as dispensing glue or coating.
There are two types of hot melt glue machines used in home appliances: one is EVA hot melt glue machine mainly used for rotating gluing on refrigerator bodies and bonding between air conditioner covers and main units as well as mattress foam bonding.The other type isPUR hot melt adhesive machine?, mainly used for(mobile phones),(televisions and computers),, etc., household(appliance products) edge sealing parts.电器产品的围边部分。
(Jingtai) hot melt glue machine has a strong temperature control system and spray control system; from heating to spraying throughout the process there is precise temperature control ensuring good spray effect which helps guarantee product quality while improving environmental friendliness.
(PUR) hot melt glue machines are more expensive than ordinary EVA machines; PUR adhesives are also more costly than regular ones. So why are they expensive? Why do some manufacturers still choose them?(PUR) hot melt glue machines have particularly high requirements for external factors.其实它还有另外一种名字(PUR) also goes by another name called moisture-reactive hot melt glue machine; one major reason being that its glue can be waterproofed so some electrical edge sealing must use (PUR) machines; however (PUR) cannot come into direct contact with air; if it does contact air then an entire barrel of (PUR) will be wasted which results in significant losses for factories.所以在购选家电行业的Therefore when selecting a (PUR)hot melt glue machine in the home appliance industryit requires careful considerationIf you want to know more information,please follow us or contact us(Jingtai)!请关注和联系我们精泰吧！
