Application of polyvinyl alcohol to thermal insulation system inside gypsum polyphenylene board external wall;

The article introduces production methods and technology of insulation board compounded with strengthened gypsum and foamed polystyrene,presents successful experience and construction methods of the insulation board which used for the first phase of the project of Hui-Long-Guan culture-residence quarter in Beijing,and so far that s the greatest economical-applicable residence quarter in China.

Study on sound absorption and insulation of gypsum board structure and its application;

Deformation of papered gypsum board and control technology of split in connection;

Study on the performance of phase change energy storing gypsum boards;

The manufacture technology of complex wall material from wheat straw and hard plasterboard was researched.

Phase-changing energy-storing gypsum wallboard was produced by directly incorporating butyl stearate with poly vinyl alcohol as dispersing agents or by imbibing those phase-changing materials.

Two kinds of phase-change energy-storing gypsum wallboards were produced by directly incorporating commercial grade butyl stearate(BS) or phase-change paraffin with poly vinyl alcohol(PVA) as dispersing agents during the process of conventional gypsum board production.
