1、粘接强度

封边完毕后，撕扯封边带，直观感受拉力强度和观察封边带粘板材木屑多少，或进行拉力剥离测试。相同条件下(指封边机、封边条、操作方法和环境相同)，选拉力强的产品。一般情况下，高温胶强度要比中低温胶强。粘结强度是影响封边质量的致关因素。

Bonding strength

After edge banding, tears edge zone and feels intuitively tensile strength and observed wood quantity, or test tensile peel. Under the same conditions (of a machine, edge banding, method of operation and environment the same), selected high tensile products. In general, high temperature adhesive stronger than the low temperature glue. Bonding strength is the key factor Influences the edge quality.

2、初粘强度和亲和力

不同品牌的热熔胶初粘强度和亲和力均有一定的差别。初粘强度高的胶，有助于增强粘结力，加大对各种类型的封边带的适应范围，但是开放时间相对偏短;亲和力好，对一些比较难封边的材料比较不会出现质量问题，根据国内封边材料的品质，PVC背胶涂布情况、三聚氰胺纸封边透胶量情况、原木皮油脂含量、木皮背面裱纸(布)湿润性，都会影响封边贴合，封边材料背面亲润性太低，会导致封边强度降低或封边脱落。选择热熔胶时，选择的热熔胶的初粘强度和粘度值要适合自己的封边材料。例如：某热熔胶封PVC封边不会脱落，封背面裱有无纺布的木皮会脱落，换另外型号热熔胶封边良好，说明某热熔胶初粘强度和亲和力较低，适用范围不广。

Initial adhesive strength and affinity

Different brands of hot melt adhesive bonding strength and affinity have some differences. Strong initial adhesive helps to strengthen the cohesive force, broaden the using ranges of various types of Edge, but the opening time is relatively short; for the materials difficult to edge, good affinity blue is comparably good for quality. according to The banding material quality, PVC coated gum, melamine paper edge sealing glue penetration amount of raw wood, oil content, wood Biaozhi ( cloth ) wet backRun, will affect the edge paste Mupi Edge material, original oil content, Mupi back paper ( cloth ) wettability, will affect the edge paste, sealing material Surface affinity of too low, cause the edge strength decreased or edge off. When selecting hot melt adhesive, make sure initial bond strength and viscosity values fit your Sealing material. For example: a hot melt adhesive closure of PVC edge will not fall off, a rear mounted with a non-woven veneer will fall off, the other types of hot melt adhesive edge is good, this explains the low bonding strength and affinity of this hot melt adhesive .

3、粘度值(粘稠程度)

粘度值能影响初粘强度和热熔胶的流动性，也影响胶的涂布。一般高温胶200℃粘度值设定在45000-120000mpa.s;封边机速度快，选的胶粘度值要中等偏大。中温胶180℃粘度值设定在20000-40000mpa.s;低温胶150℃粘度值设定在15000-25000mpa.s;粘度值的大小不代表粘结强度。

Viscosity ( viscous degree )

Viscosity values influences the initial bonding strength and hot melt fluidity, also affect the adhesive coating. General high temperature glue viscosity at 200 ℃value setting in 45000-120000mpa.s; if Edge banding machine is speedy, glue viscosity value should be medium to large. Medium temperature plastic viscosity at 180 ℃values set in the 20000-40000mpa.s; low temperature glue viscosity at 150 ℃values set in the15000-25000mpa.s; viscosity value does not mean bond strength.

4、热流动性

流动性影响胶的涂布均匀程度和胶对板材的渗透性、湿润性。流动性不好，涂胶时会涂胶不均，断断续续;流动性不好，胶不能渗透到板材，不能形成“胶钉”状胶膜;所以选热熔胶时，优先选相同温度相同粘度值下流动性好的产品。

Heat flow

Liquidity effects adhesive coating uniformity and adhesive sheet permeability, wettability. Not good fluidity, glue is uneven, and mobility; Not good, glue cannot penetrate into the sheet, cannot form the Film adhesive like “Gel Nail " so when selecting hot melt adhesive, good mobility product is better under the same temperature the same viscosity value.

5、抗热性

现在很多家具需要装在集装箱里长途运输或飘洋过海出口国外，集装箱里温度很高，热熔胶需有一定的抗热性，封边条才不会脱落，抗热性不能低于摄氏60度，应选择抗热性高一点的产品。中低温胶的抗热性一般是55-65℃，高温胶的抗热性一般是68-75℃，高温胶抗热性>中温胶>低温胶。

Heat resistance

Now a lot of furniture are installed in containers and shipped to the foreign country through long-distance transport, the temperature in container is high, so to make sure sealing Edge will not come off, hot melt adhesive needs to have a certain resistance, a high heat-resistant product is the right choose, heat resistance should be no less than 60 degrees Celsius. Low temperature plastic thermal resistance is generally 55-65℃, high temperature adhesive Heat resistance is generally 68-75℃, the temperature is high, the product is better.

6、涂胶量(效益)

好热熔胶一般涂胶量150-200g/ m2,如果填充料过多，涂胶量会增大，某些品质一般热熔胶有的涂胶量达到250-300g/ m2，虽然价格较低，但不见得会降低成本，而且胶线粗，影响美观。优先选涂胶量低的产品。

Glue spreading amount ( benefit )

The good Hot melt adhesive generally contents 150-200g/m2, if the filler is overmuch, glue spreading amount increases, some hot melt adhesive with general quality reached 250-300g/m2, Although the price is low, but cannot reduce the cost, and the glue line thick, Affect the appearance. coating low volume products are better to choosef.
