本公司采用先进的生产技术和设备，把颜料在不同的改性树脂体系中进行预先分散，用于高档油墨、油漆和涂料的生产，主要产品有脂溶和醇溶型硝化棉预分散颜料色片、水性丙烯酸预分散颜料色片、氯醋聚合物预分散颜料色片、乙酸丁酸纤维素预分散颜料色片、聚乙烯醇缩丁醛预分散颜料色片等。

However, the effect of ARF on Fe availability was enhanced relatively in the same way with time on these two different calcareous soils.

因此，酸性根际肥在一定程度上可减少肥料氮的硝化损失，提高肥料氮的利用率，同时对环保也具有一定的意义。

It was synthesized on the basis of carbazole by two steps reaction of nitrosation and reduction.

以咔唑为起始原料，经亚硝化和还原两步反应合成N-氨基咔唑。

This research's goal is develops one kind of high performance the emulsion cellulose nitrate lustre-coating agent, while maintains the resolver superiority enhances the emulsion stability.

本研究的目的是研制一种高性能的乳液型硝化纤维光亮剂，在保持溶剂型优势的同时提高乳液型的稳定性。

Cellulose Nitrate; Nitrocellulose containing a maximum of 12.6% Nitrogen

硝酸纤维素；硝化纤维素含氮量不超过12.6

The results showed that phosphating followed by coating acrylic acid can improve the adhesive strength. Increasing water temperature and the concentrations of cellulose nitrate in the buffer layer, decreasing the concentrations of R-2 resin and solvent can reduce the elongation.

结果表明，铝材表面经过磷化处理后，用丙烯酸金属涂料涂覆，可提高水转印后粘接性，转印时水温升高，过渡层配方中硝化棉增多，随R-2树脂减少，以及溶剂的减少都会使伸长率下降。

DSPI MV-series f-imagnat innovativeink, binders is cellulose nitrate, alcohol-soluble, table, heat-resistant up to 160 ° c.

DSPI的MV—F—KA系列油不朱，拆闭料是硝化纤维素，醇溶性，边印，耐矮温可达160℃。

The cellulose nitrate lustre-coating agent's has surpassed for 100 years in leather Tu Shi application, because it surpassed the casein, the acrylicresin, the polyurethanes lustre-coating agent and the low in price obviously in the top layer Tu Shi overall performance obtained the widespread application.

硝化纤维光亮剂在皮革涂饰中的应用已超过一百年，因其在顶层涂饰中的综合性能明显优于酪素、丙烯酸树脂、聚氨酯类光亮剂且价格低廉而得到了广泛的应用。
