Jowapur®粘合剂获得国际认证
德国胶王公司推出全新单组份反应型聚氨酯粘合剂用于承重结构胶合木粘接。
近来，适用于承重结构胶合木粘接的Jowapur®粘合剂获得国际认证的类型增加。此系列5款粘合剂产品，是胶王公司单组份反应型聚氨酯产品线的延伸; 产品拥有不同特性以及操作性能，满足了承重木结构领域客户对专用粘合剂的需求。
相比于其他类型的粘合剂有着多种不同的用途，胶王公司开发的专用聚氨酯粘合剂适用于特殊用途，是各自的最佳选择。
相比于一般粘合剂，用于建筑方面的Jowapur®系列粘合剂在组成、性能、加工参数方面有着很大的差异，因为它们是用于特殊用途。这些粘合剂是承重结构胶合梁粘接的最佳选择。
胶王公司Jowapur®单组份聚氨酯粘合剂的特性如下：
单组份、无需混胶、无需养生、无浪费
除以上特性外，Jowapur®粘合剂发泡程度低，这就意味着木结构在间歇性存放时，避免了粘接在一起的风险，同时对于加工机械的污染程度降到最低。此外，在双面刨，平刨或压刨操作时，使加工更加平顺与便捷。
胶王公司先进的生产工艺以及用于稳定粘合剂的化学添加剂使得即便在存储时间较长与温度较高的情况下，增强纤维也不会从粘合剂分离。在整个操作时间内，粘合剂不会形成胶块，避免了堵塞设备喷头。

Carrying a lot of weight - Multifaceted adhesives for load-bearing glulam
Load-bearing glulam plays a growing role in the construction industry and the use of load-bearing glulam in new buildings has been increasing for years. Intense development efforts are underway to make sure the technology meets the growing quality requirements. Jowat, the adhesives specialist from Detmold, supports that development with its know-how acquired over many years, an optimum service, and with a brand new, fully certified set of adhesives.
The right answer for every need
The new adhesives are certified according to EN 15425:2017 and their composition, characteristics, and processing parameters are specifically tailored to the requirements of load-bearing glulam applications. They can be used for fingerjointing as well as for laminating, offer the choice of assembly times between 10 and 60 minutes, and for the first time facilitate an assembly-pressing time ratio of 1:1. Industrial users can therefore optimise their processes by choosing the product best-suited for their needs. A simple change of adhesive, for instance, can help increase their production capacity or alternatively improve process reliability without the need for major investments.
Clear benefits: PUR
Compared with other adhesive systems for the manufacture of load-bearing timber components, polyurethane adhesives provide several advantages in the manufacturing process and quality of the end product because of their characteristics. They are completely free of formaldehyde and require significantly lower application amounts due to a solids content of 100 %. Depending on the formulation, the prepolymers cure at room temperature already within a very short time and are colourless, with no discernible glue line. The adhesives from the Jowapur® series are processed as a one-component system, making mixing, pot life, and adhesive remnants from production obsolete. The limited foaming can help prevent the lams from sticking together when they are temporarily stacked on top of each other or placed next to each other, and therefore considerably reduces the cleaning effort.
The Jowapur® prepolymers are reinforced with fibres that increase the bond strength and prevent the assemblies from sliding apart in the manufacturing process and while the adhesive is curing. Due to optimised flow properties, these adhesives are ideal for contactless application systems in fingerjointing units.
Impressive constructions
From Jowat’s point of view, glulam will continue to become more and more significant in future – a development that should be accelerated with optimised adhesives. “Building with engineered timber brings only advantages,” says Ralph Kirst, responsible for load-bearing glulam business development at Jowat SE. “Furthermore, adhesive bonding facilitates the manufacture of timber constructions in less time and at lower costs. Entire buildings can be prefabricated in mass production and assembled on site.” In light of these advantages, chances are more and more property developers will start using engineered timber. Not only does it make sense from an economic and ecological point of view – wood stores CO2 and helps fight against climate change. Glulam also allows for virtually limitless possibilities in modern architecture, as is demonstrated by the eye-catching design of Jowat’s “House of Technology” in Detmold or the BUGA Wood Pavilion in Heilbronn.
