(一）根据胶的成分的不同，用于建筑用胶合板的胶有如下几种：
　　脲醛胶：防潮胶水/用于室内装修、家俱，不可用于室外。
　　三聚氰胺胶：防潮、并具有一定的耐水煮、耐气候特性/可用于室外或者室内、但不可以经常被水浸渍。
　　酚醛胶：防潮、优秀的耐水煮、耐气候特性/可用于室外或者室内、可经受室外风吹雨打。
　　（二）根据环保等级，用于胶合板的胶可以分为E0级,E1胶，E2胶（以及连E2级都达不到的不合格的胶）。E0级是最高环保等级。E1级胶做的胶合板就可以直接用于室内了。
　　高质量的脲醛胶/三聚氰胺胶/酚醛胶都可以达到E0级、E1级，即都可以直接用于室内。
　　（三）环保建议：
　　1、如果要制作一般室内用的木制品，可以使用E1级（甚至E0级）脲醛胶；如果进一步想让该木制品有更强的防水防潮性能的话，可以使用E1级（甚至E0级）三聚氰胺胶。
　　2、如果你要制作室外用的木制品，可以使用E1级（甚至E0级）酚醛胶。

(I) According to the different components of glue, there are several types of glue used for construction plywood:

Urea-formaldehyde glue: moisture-proof glue/used for interior decoration and furniture, not for outdoor use.

Melamine glue: moisture-proof, and has certain water boiling resistance and weather resistance characteristics/can be used outdoors or indoors, but cannot be frequently immersed in water.

Phenolic glue: moisture-proof, excellent water boiling resistance and weather resistance characteristics/can be used outdoors or indoors, and can withstand outdoor wind and rain.

(II) According to the environmental protection level, glue used for plywood can be divided into E0, E1, E2 (and unqualified glue that does not even reach E2). E0 is the highest environmental protection level. Plywood made of E1 glue can be used directly indoors.

High-quality urea-formaldehyde glue/melamine glue/phenolic glue can reach E0 and E1 levels, that is, they can all be used directly indoors.
(III) Environmental protection suggestions:

1. If you want to make wooden products for general indoor use, you can use E1 (or even E0) urea-formaldehyde glue; if you want to make the wooden products more waterproof and moisture-proof, you can use E1 (or even E0) melamine glue.

2. If you want to make wooden products for outdoor use, you can use E1 (or even E0) phenolic glue.
