Production Process
Backing Fabric Inspection
A. Measure the thickness and weight,inspect the appearance.
B.Record the color spot, dirty spot and fracture.
C.Test the tensile strength, tear strength ,elongation rate and seam slippage.
01
Release Paper Inspection
Check the fracture and damage spot of the release paper.
The operative standard is that there should be less than 3 paper scars within 100 meters and less than 6 fracture within 1500 meters.
02
Resin Preheating
Preheat the resin 24 hours before production.
03
Mix The Ingredients
Weigh the ingredients according to the product formula and mix them evenly.
04
Pretest The Ingredients
Put the prepared resin into the test beaker according to the proper proportion, to check the adhesive degree and bubble state. The engineer observes the foam density and test the adhesive hardness and maturity.
05
Resin Into The Tank
The resin is put into the special storage tank for mixing, temperature control and vacuum.
06
Unwind The Release Paper
After the release paper is unwound, pay attention to the tension control and abnormal control. The tension is controlled within 0.4 to 0.5.
07
Prepare Top Layer Ingredients
Weigh the resin ingredients according to the product formula and mix them evenly.
08
First Coating of Top Layer
Apply the prepared resin onto the release paper, then scrape it to make it flat.
09
Oven Operation And Control For The First Coating
10
Second Coating Of Top Layer
Apply the prepared resin onto the first coating, then scrape it to make it flat.
11
Oven Operation And Control For The Second Coating
12
Pipe Temperature Control
Control the temperature of the pipeline from storage tank to resin nozzle.
13
Temperature Control Of Coating Head
14
Scraping Resin
Spray the mixed resin from the coating head and apply it to the second coating layer.
15
Oven Operation And Control For Third Coatin
16
Backing Fabric opening
Open the backing fabric at the right speed on the top of the opening machine.
17
Resin Molding And Gluing
Through the temperature regulation mechanism of long oven, the resin layer and backing fabric can be glued and molded.
18
Inspection During The Production
Cut a small piece of the product every 100 meters and check the weight, thickness, color and hand feeling.
19
Separation Of Release Paper And Rolling
Peel the release paper from the finished products and roll the finished products.
20
Inspection and Roll Classification
Inspect the finished products, pack them in rolls, and classify them according to the customers' requirements.
21
Inspect The Thickness, Width And Weight Of The Finished Products
22
Complete Physical Property Test Of The Finished Products
Based on clients' demanded specifications, test all the performances and properties of the finished products.
23
Store The Finished Products In Warehouse, Waiting For Delivery
