This paper introduces the effect of the complex addition of phosphate on improving the water-resistant feature of Magnesium cement and makes a preliminary discussion about the addition improving mechanism of water-resistant Magnisium cement.

Investigation on Packing Technique of Corrugated Board with Waterproof and Moisture-holding;

Hydration resistance of AlN powder and the application of AlN powder to corundum spinel castables;

Surface modification of CaO clinker and its hydration resistance;

Applying the mechano chemistry method, raw material of CaCO 3 and Ca(OH) 2, the influence of the time of mechanical active on the hydration resistance has been investigated in this paper.

Study on adhesive strength and water resistance of wood glue based on modified wheat gluten;

The mechanical properties,water resistance,and transparency of the CES/PVA film were investigated,and a morphological microscopical analysis(SEM) was performed to study surface properties of the films.

The stability,water resistance,and other performances of the water-based ink are not very ideal,which is a great impediment to its development and application in packaging and printing industry.

The results indicated that the use of surface sizing agent can improve the water-resistance of paper and reduce the addition level of internal sizing agent.

The results proved that the use of the AGP as a surface sizing agent can improve the water-resistance of the paper and reduce the use of the internal sizing agent.

Their structure properties were introduced at first, then through the experiment, the benefit of SMA(r) Resin in improvement of water-resistance, ink-jet printability, porosity and coefficient of friction of treated paper was explained;and through the laboratory experi.

A special waterproof agent on the spray-ink typewrite paper;
