刮刀式涂布 利用刮刀的揩抹作用以达到将压敏胶粘剂均匀涂抹在基材表面。

scraper coating is made by wiping the scraper to achieve the uniform application of pressure sensitive adhesive on the surface of the substrate.

转移涂布,将医用透气胶带的基材(医用无纺布)与预先涂有压敏胶粘剂的防粘性基材(医用硅油纸)加压复合,从而使压敏胶粉剂从医用硅油纸的表面转移到医用无纺布上。

the substrate (medical nonwoven fabric) of the medical permeable adhesive tape is compacted with the anti sticky substrate (medical silicon paper) coated with pressure-sensitive adhesive (medical silicone paper) in advance to transfer the pressure sensitive adhesive powder from the surface of medical silicone paper to the nonwoven fabric.

凹印涂布 利用圆形棍筒表面上均匀或规则排布的凹印坑,将粘度小的液体胶均匀转移到医用透气胶带的基材上。

gravure printing uses uniform or regularly arranged gravure pits on the surface of the circular cylinder to transfer the small viscosity liquid adhesive onto the substrate of the medical breathable adhesive tape.

挤出涂布 利用压力将压敏胶由缝隙中挤出,并涂抹于医用透气胶带基材表面。

extrusion coating uses pressure to squeeze pressure sensitive adhesive from the gap and smear it on the surface of medical breathable adhesive tape.

其实,医用透气胶带基本上都属于转移涂布,先将医用热熔胶或医用溶剂胶先涂布到医用硅油纸上,然后经过加压复合将硅油纸表面胶黏剂转移到医用无纺布上,从而加工成医用透气胶带,常见的挤出涂布主要用于热溶胶,溶剂胶主要用刮刀涂布法,也有用凹印涂布法的。

in fact, the medical permeable adhesive tape is basically a transfer coating. first, the medical hot melt adhesive or the medical solvent glue is first coated on the medical silicone paper, then the silicone oil paper surface adhesive is transferred to the medical nonwoven fabric through pressure compound, and then the medical air permeable adhesive tape is processed. the adhesive is mainly coated with scrapers and gravure coating.
