Packer Reinjector Syringe Injector

대화정밀공업은 최고 품질의 자재를 생산하기 위해 노력합니다.: Syringe Injector

Characteristics

As the movement of injected resin is enlarged in concentric circles, no defect or separation is generated by the injection pressure.
Made of transparent material, users easily observe the injection volume with Clear eyes.
As it allows users to repair the structure cleanly while maintaining the original status and without dismantling or entering down, Is costs less repair expense and saves time for work.
As injection is made by low pressure similar to the one generated by a rubber band, it causes less damage to the sealed area. And also to offers high work precision, construction management is make easier.

Syringe injector Injection System

01. Surface cleaning

Examine the crack status, width, depth, and others prior to deciding injection method.

02. Marking the bench positions

If the concrete thickness is 200mm~300mm and the crack width is 1mm or less.
Five benches are required per meter in general. The required number of benches Depends on concrete thick ness and crack width, Decide and mark where to place the fixing Plates after checking the crack status.

03. Attaching the benches

Attach and fix the injection benches with epoxy sealing material. Make sure that sealing material is applied to the benches seamlessly.

04. Sealing

Perform 1mm-thick, 30mm-wide epoxy sealing on the crack except the parts where he benches are placed. in an effort to prevent injection material from Overflowing the crack.
Verify that sealing material has hardened sufficiently.

05. Injection

Fill the injection material to cylinder body, insert it into the fixing plate, and then fix it with elastic cord or spring.
(To be noted, you need to replace the cylinder body with a recharged one if more than 30cc of injection is required.)
