在購買點膠機之前你要知道這些！
在你買點膠機之前，有兩件事你需要知道:
Before you buy a water dispenser, there are two things you need to know:
1. 使用膠水的基本特性:
1. The basic characteristics of glue:
它是什么膠水?單組分還是雙組分(AB膠)?
What kind of glue is it? One component or two component (AB glue)?
膠水是一種把兩個物體粘在一起的物質。膠水不是獨立存在的。它必須分散在兩個物體之間才能結合。
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膠是兩種液體混合硬化膠的另一個名字,一個液體膠,一個液體硬化劑,兩液相混合,強化能力,沒有必要努力依靠溫度應該成熟,是一種常溫硬化膠,做模型能夠使用有時哦!
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)如果是雙組分，AB膠的體積比是多少?
2) If it is two-component, what is the volume ratio of AB glue?
所謂的雙組分AB，在室溫下固化，組分A(也稱為組分A)，主要是e-44環氧樹脂，因為e-44環氧樹脂
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)膠水的粘度和密度是多少?
3) What is the viscosity and density of the glue?
用布氏粘度計(以CPS厘泊為單位)測定膠水的粘度。這種膠水的粘度通常在300到300立方厘米之間。在水溶性膠粘劑中，固體含量并不決定膠水的粘度，而是取決于膠水配方中的增塑劑、增粘劑等，影響膠水的粘度。一般情況下，周邊環境溫度為較高的“粘度↓”、“溫度↓粘度↑”。27℃時水的粘度為“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.
膠水要多久才能凝固?完全固化時間嗎?
How long does it take for the glue to solidify? Is it fully solidified?
膠水和密封膠應在一定的環境下使用。在使用條件上，有應力條件、環境溫濕度、化學介質條件、室外條件等。
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)壓力。當粘接劑受剝離力和不均勻拉力作用時，可使用較好的韌性，如橡膠膠、聚氨酯膠等。當受到均勻的拉力、剪切力時，可選用硬度和強度適中的膠水，如環氧膠、丙烯酸膠等。
(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)溫度。不同的膠水具有不同的耐熱性。根據溫度使用不同的膠水。
(2) Temperature. Different glues have different heat resistance. Use different glue according to temperature.
(3)濕度。潮濕和潮濕對膠粘劑界面的穩定性是非常不利的，可以說是有害而無益的。由于水分子體積小，極性大，通過滲透、擴散，起到一種水解作用，使膠水連接表面破壞或自行脫落，使膠水連接強度和耐久性降低。膠粘劑零件要求良好的耐水性，可選用環氧膠粘劑、聚氨酯膠粘劑等。
(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)化學介質?；瘜W介質主要是指酸、堿、鹽、溶劑等，不同類型的膠水，不同的固化條件，具有不同的耐介質能力。因此，根據膠粘劑的接觸介質來選擇膠水和密封劑。
(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)戶外條件。采用室外的膠水連接條件比較復雜，氣溫變化大，風吹雨淋，日曬凍結，會加速膠水層老化，使壽命縮短。因此，在室外條件下，膠水要選用高溫固化和抗老化的膠粘劑，如酚醛縮醛膠粘劑、環氧丁腈膠粘劑;硅膠密封膠用于密封。
(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. 配藥工藝要求:
2. Requirements of dispensing technology:
1)配藥精度的要求是什么?每種產品使用多少膠水?
1) What is the requirement of dispensing accuracy? How much glue does each product use?
2)封口用膠水嗎?粘貼?絕緣?水分?靜脈滴注法?
2) Glue for sealing? Adhesion? Insulation? Moisture? Intravenous drip?
3)如何實施配藥操作?
3) How to implement dispensing operation?
