1. the no streamline trace in surface and do not have the method for making of thermoplastic polyvinyl chloride'"'"'s soft transparent adhesive plaster of indenture comprises:

  • A. the thermoplastic soft transparent rubberized fabric does not have the formation of streamline trace, and main dependence makes sizing material roll after water-bath mechanism quick cooling reaches micro-crystallization effect at the rolling press wheel face, impels to reach no streamline trace in surface and bright characteristic;

    B. dispose water removal device,, enhance productivity by the moisture that is attached to the adhesive plaster surface after the water-bath is removed;

    C. dispose the heating, drying section, will cool off and the merging of heating again, make adhesive plaster obtain fully to finalize the design and keep suitable coiling temperature (30~

    85 ℃

    ) at the cooling wheels;

    The suitable adhesive plaster temperature (30~

    85 ℃

    ) of control when d. transparent rubberized fabric batches, and give adhesive plaster suitable pressure 1~

    8kg/cm 2, air is involved in finished product when preventing to batch, and reaches the characteristic of the no indenture in surface;

    E. before batching, by in the each several part cooling wheel, feeding hot water and control constant temperature, and be coated with cloth or other water-absorbing material at wheel face, make adhesive plaster through out-of-date, except that drying the residual moisture, also obtain required coiling temperature;

    F. on the adhesive plaster under the control proper temperature or at the spool center, apply suitable pressure, enable to prevent from fully to be involved in air, and realize the required no indenture outward appearance of finished product.
