Tai''an glass steel tube manufacturers: causing delamination causesSolutions

At present in the world by reciprocating filament winding process for tube manufacturers than the other two production technology manufacturers moremore, one of the reasons is reciprocating filament winding process for the manufacture of glass steel pipe has a more extensive use, Applicability Comparison well.

China begins from 70 time small batch production of FRP pipe, after 20 years of development and practical application show that, our country glass steel pipeline industry develops slowly. Compared with the developed countries, in raw materials, equipment, technology management, engineering design, product standard, construction standard, application rangeso on are put in very big difference.

Glass tube caused by stratified reasons : ①tape too old; the adhesive resin content is too little or not uniform; the hot roll temperature is too low, the melted resin is not good, not good adhesive to stick a tube core; the tape tension is small; the mold release agent dosage is too much, the core fabric.

Solution:①adhesive glue content, soluble resin glue content to meet the quality requirements; the hot roll temperature adjustable high, make the tape after the heat roller, sticky tape is weak, can be firmly glued the tube core; the tape tension adjustment;④no oily agents from loss or reduction of its dosage.
