1、看包装。不宜选用外包装粗糙、容器外形歪斜，使用说明等文字印刷模糊的商品。外包装粗糙的商品质量很难得到保证。
1. Look at the package. It is not advisable to choose goods with rough outer packing, skewed containers and vague printed instructions. It is difficult to guarantee the quality of rough outer packing.
2、看生产日期。注意察看胶粘剂外包装上注明的生产日期，过期的胶粘剂质量和效果会下降。
2. Look at the date of production. Attention should be paid to the date of production indicated on the outer package of adhesives. The quality and effect of the expired adhesives will decrease.
3、开桶查看。胶粘剂的胶体应均匀、无分层、无沉淀，开启容器时无冲鼻刺激性气味。
3. Open the barrel. Adhesive colloid should be uniform, no layers, no precipitation, no irritating odor when opening the container.
4、根据被粘物的物理性质选择胶粘剂粘接脆性和刚性材料(如陶瓷、玻璃、水泥和石料等〉，选择强度高、硬性大和不易变形的热固性树脂胶粘剂，如环氧树脂脂肪酸胶、酚醛树脂胶和不饱和聚酯胶;粘接弹性和韧性材料(如橡胶、皮革、塑料薄膜等)，选择弹性好、有一定韧性的胶粘剂。
4. Choose adhesives to bond brittle and rigid materials (such as ceramics, glass, cement and stone) according to the physical properties of the adhesives. Choose thermosetting resin adhesives with high strength, high hardness and non-deformability, such as epoxy resin fatty acid adhesives, phenolic resin adhesives and unsaturated polyester adhesives; Adhesive elasticity and toughness materials (such as rubber). Leather, plastic film, etc.) Choose an adhesive with good elasticity and certain toughness.
