Before you buy a water dispenser, there are two things you need to know:

　　1. 使用胶水的基本特性:

　　1. The basic characteristics of glue:

　　它是什么胶水?单组分还是双组分(AB胶)?

　　What kind of glue is it? One component or two component (AB glue)?

　　胶水是一种把两个物体粘在一起的物质。胶水不是独立存在的。它必须分散在两个物体之间才能结合。

　　Glue is a substance that binds two objects together. Glue does not exist independently. It must be dispersed between two objects in order to combine.

　　AB胶是两种液体混合硬化胶的另一个名字,一个液体胶,一个液体硬化剂,两液相混合,强化能力,没有必要努力依靠温度应该成熟,是一种常温硬化胶,做模型能够使用有时哦!

　　AB glue is another name of two kinds of liquid mixed hardening glue, a liquid glue, a liquid hardening agent, two liquid mixing, strengthening capacity, there is no need to rely on temperature should be mature, is a room temperature hardening glue, can be used to make models sometimes!

　　2)如果是双组分，AB胶的体积比是多少?

　　2) If it is two-component, what is the volume ratio of AB glue?

　　所谓的双组分AB，在室温下固化，组分A(也称为组分A)，主要是e-44环氧树脂，因为e-44环氧树脂

　　So-called two-component AB, cured at room temperature, component A (also known as component A), mainly E-44 epoxy resin, because E-44 epoxy resin

　　3)胶水的粘度和密度是多少?

　　3) What is the viscosity and density of the glue?

　　用布氏粘度计(以CPS厘泊为单位)测定胶水的粘度。这种胶水的粘度通常在300到300立方厘米之间。在水溶性胶粘剂中，固体含量并不决定胶水的粘度，而是取决于胶水配方中的增塑剂、增粘剂等，影响胶水的粘度。一般情况下，周边环境温度为较高的“粘度↓”、“温度↓粘度↑”。27℃时水的粘度为“1”。

　　Viscosity of glue was measured by Brinell viscometer in CPS centipotes. The viscosity of this glue is usually between 300 and 300 cubic centimeters. In water-soluble adhesives, the solid content does not determine the viscosity of the glue, but depends on the plasticizer and tackifier in the formula of the glue, which affects the viscosity of the glue. Generally, the ambient temperature is higher "viscosity_", "temperature_viscosity_". The viscosity of water is "1" at 27 C.

　　胶水要多久才能凝固?完全固化时间吗?

　　How long does it take for the glue to solidify? Is it fully solidified?

　　胶水和密封胶应在一定的环境下使用。在使用条件上，有应力条件、环境温湿度、化学介质条件、室外条件等。

　　Glue and sealant should be used in a certain environment. In terms of using conditions, there are stress conditions, environmental temperature and humidity, chemical medium conditions, outdoor conditions and so on.

　　(1)压力。当粘接剂受剥离力和不均匀拉力作用时，可使用较好的韧性，如橡胶胶、聚氨酯胶等。当受到均匀的拉力、剪切力时，可选用硬度和强度适中的胶水，如环氧胶、丙烯酸胶等。

　　(1) Pressure. When adhesives are subjected to peeling force and non-uniform tensile force, better toughness can be used, such as rubber, polyurethane, etc. When subjected to uniform tension and shear force, glue with moderate hardness and strength, such as epoxy and acrylic, can be selected.

　　(2)温度。不同的胶水具有不同的耐热性。根据温度使用不同的胶水。

　　(2) Temperature. Different glues have different heat resistance. Use different glue according to temperature.

　　(3)湿度。潮湿和潮湿对胶粘剂界面的稳定性是非常不利的，可以说是有害而无益的。由于水分子体积小，极性大，通过渗透、扩散，起到一种水解作用，使胶水连接表面破坏或自行脱落，使胶水连接强度和耐久性降低。胶粘剂零件要求良好的耐水性，可选用环氧胶粘剂、聚氨酯胶粘剂等。

　　(3) Humidity. Moisture and humidity are very harmful to the stability of the adhesive interface, which can be said to be harmful and unhelpful. Because of the small size and large polarity of water molecules, it plays a hydrolytic role through penetration and diffusion, which destroys or sheds the surface of glue connection, and reduces the strength and durability of glue connection. Adhesive parts require good water resistance. Epoxy adhesives and polyurethane adhesives can be selected.

　　(4)化学介质。化学介质主要是指酸、碱、盐、溶剂等，不同类型的胶水，不同的固化条件，具有不同的耐介质能力。因此，根据胶粘剂的接触介质来选择胶水和密封剂。

　　(4) Chemical medium. Chemical medium mainly refers to acid, alkali, salt, solvent, etc., different types of glue, different curing conditions, different media resistance. Therefore, glue and sealant are selected according to the contact medium of the adhesive.

　　(5)户外条件。采用室外的胶水连接条件比较复杂，气温变化大，风吹雨淋，日晒冻结，会加速胶水层老化，使寿命缩短。因此，在室外条件下，胶水要选用高温固化和抗老化的胶粘剂，如酚醛缩醛胶粘剂、环氧丁腈胶粘剂;硅胶密封胶用于密封。

　　(5) Outdoor conditions. The outdoor glue connection conditions are complex, the temperature changes greatly, the wind and rain, the sun freeze, will accelerate the ageing of the glue layer, and shorten the life of the glue layer. Therefore, in outdoor conditions, high temperature curing and aging resistant adhesives, such as phenolic acetal adhesives, epoxy nitrile butadiene adhesives, and silicone sealants are used for sealing.

　　2. 配药工艺要求:

　　2. Requirements of dispensing technology:

　　1)配药精度的要求是什么?每种产品使用多少胶水?

　　1) What is the requirement of dispensing accuracy? How much glue does each product use?

　　2)封口用胶水吗?粘贴?绝缘?水分?静脉滴注法?

　　2) Glue for sealing? Adhesion? Insulation? Moisture? Intravenous drip?

　　3)如何实施配药操作?

　　3) How to implement dispensing operation?
