涂剂

Besides, the application of PUA that we synthesized in UV curable leather finishing was studied.

其次，论文对所合成水性UV 聚氨酯丙烯酸酯在皮革涂饰剂中的应用进行了研究。

This step is important for removal of any puddled primers so that there is no interference in complete seating of the post.

这一步对于多余的涂底剂去除至关重要，这样才能使桩完全的无任何阻碍的就位。

The study evaluated the influence of the two different polyol's raw material origins and the different dispersing additives in the polyurethane coatings formulations on the weathering resistance by glossmetry, spectrocolorimetry, chalking test, infrared spectroscopy etc. The influence of light stabilizer and dispersant on the degradation characteristerics of polyurethane coating has also been evaluated. Ultraviolet radiation from sunlight causes the chalking of resin and the fading of pigment by breaking down the chemical bonds in coatings.

本实验将配制成不同灰色聚氨基甲酸酯涂料配方，加入硬化剂后涂装在试片上，待自然风乾后，制成不同配方涂膜试片，进行加速风化耐候利睑、光泽度、分光色差、粉化、红外线光谱仪等测试，探讨不同的聚醇树脂原料来源，与不同的润湿分散添加剂种类，对於聚氨基甲酸酯涂料耐候性质的影响。

Methods: Using to orthogonal design select the emulsifying agent of progest cream,based on the appearance, subtleness, and stability.

以外观、涂展性、细腻性及稳定性为考察指标，采用正交设计，以综合打分的方式筛选乳化剂。

Respectively, glutamic acid derivatized β-CD has been synthesized with epoxy chloropropane as the intermediate, a water-insoluble yellow liquid was got after the acetylating of the by using acetic anhydride, which was used as a novel gas chromatographic CSP; A water-soluble β-CD polymer cross-linked with epoxy chloropropane has been synthesized, and the derivatives of β-CD polymer were synthesized by its alkylating and acetylating. The different β-CD derivatives were coated on silica capillary columns by dynamic method, the chromatographic properties and retention behaviors of the fused silica capillary columns were studied, the results showed that the β-CD derivatives had good stereoselectivity and separation results to some compounds, especially to various positional isomers and enantiomers.

本文还分别以环氧氯丙烷为中间体，合成了七{2，6-二-O-[3-(1，3-二羟基丙氨酸)]}-β-环糊精，再用醋酸酐将其乙酰化，得到了一种淡黄色粘稠液体，合成了一种新型的环糊精衍生物；以环氧氯丙烷作交联剂合成了一种水溶性的β-环糊精聚合物，再将其烷基化和酰基化，合成了β-环糊精聚合物的不同衍生物，用动态法将不同类型的β-环糊精衍生物涂渍在石英毛细管柱上，通过对所制备柱柱性能的测试和对一系列化合物的分离和保留行为的研究，结果表明所合成的β-环糊精衍生物对各类化合物，特别是对位置异构体和对映异构体具有较好的分离效果，显示了很强的立体选择性。

Formerly, surface painting or admixing with water repellent admixture had low efficiency and relatively high cost.

以往 ，表面涂覆或掺加憎水剂，效果不大而且昂贵。

The gold bonder and sand blasting can significantly improve the bond strength of porcelain fused electroformed pure gold copings.

金沉积基底与瓷的结合力低于Ni-Cr合金；基底表面喷砂和涂金黏结剂能增强金沉积基底与瓷的结合强度。

A KV5O13x-C positive electrode was prepared by using a combined method of two steps for the electrolyzing and heat treatment without the use of the adhesive.

摘 要：在没有涂敷粘结剂的条件下，采用电解和热处理相结合的两步法直接制得KV5O13 x -C正极。

In both cases, operations should be stopped and the joints disassembled, recleaned and fluxed.

在这些情况下，连接作业应该停止，并且拆开连接部件，重新清洗并且涂敷焊剂。

Immediately after fluxing, the parts to be brazed should be assembled.

焊剂涂敷后，应该立即进行铜焊组装。

Plunder melds and run with this jewel!

掠夺melds和运行与此宝石！

My dream is to be a crazy growing tree and extend at the edge between the city and the forest.

此刻，也许正是在通往天国的路上，我体验着这白色的晕旋。
