Today we will introduce our knowledge about glue and core slurry transfer.

　　一、什么是胶浆和芯浆:

　　1. What is mortar and core slurry?

　　胶芯胶是溶解在溶剂中形成一定粘度的胶芯胶。经溶剂挥发后，其成分与芯胶完全相同。

　　Core rubber is a kind of core rubber which dissolves in solvent to form a certain viscosity. After solvent evaporation, its composition is ident to that of core rubber.

　　在输送带过程中，常用的胶水是指:用芯胶和溶剂(如甲苯、二甲苯、溶剂汽油等)按1:5-1:6的比例调制而成。

　　In the conveyor belt process, the commonly used glue refers to: using core glue and solvent (such as toluene, xylene, solvent gasoline, etc.) in proportion of 1:5-1:6.

　　芯胶是由压延机薄膜进行压延的，其分子顺序是通过取向，从力学角度看具有各向异性，所以沿压延方向拉伸性能好，抗疲劳性能好。溶剂中的橡胶分子是随机排列的，各向同性的。

　　Core glue is calendered by calender film. Its molecular order is orientation. It has anisotropy from the mechanical point of view. Therefore, it has good tensile properties and fatigue resistance along the calendering direction. Rubber molecules in solvents are randomly arranged and isotropic.

　　两者的角色是什么?

　　What are the roles of both?

　　胶水的作用:

　　The function of glue:

　　通过溶剂良好的流动性和渗透性，溶解在熔融基体中的橡胶能充分进入织物，使橡胶能更好地与织物结合。

　　Through the good fluidity and permeability of the solvent, the rubber dissolved in the melt matrix can fully enter the fabric, so that the rubber can better combine with the fabric.

　　芯胶功能:

　　Core glue function:

　　使带布层粘合在一起,与此同时,传送带由于不同厚度引起的层间应力、变形的差异,和学习一些毁灭性的能量,所以核心胶水在传送带上不可或缺的一部分,一些外国制造商为了延长使用寿命,通常采用的方法增厚橡胶芯的厚度。

　　At the same time, because of the difference of stress and deformation between layers caused by different thickness of conveyor belt and learning some destructive energy, the core glue is an indispensable part of conveyor belt. In order to prolong service life, some foreign manufacturers usually use the method of thickening the thickness of rubber core.

　　在这里我们以金自豪的输送带来说明，如果只使用刷胶而不使用芯胶，那么胶的厚度在布层之间的连接处相对较薄，其使用效果也会有影响。

　　Here we are proud of the gold conveyor belt. If only brush glue is used instead of core glue, then the thickness of glue is relatively thin at the junction between layers of cloth, and its use effect will also be affected.

　　二、有客户会问，不同厂家的芯胶能混吗?

　　Second, some customers will ask, can the core glue from different manufacturers be mixed?

　　这里我们不金傲输送带与不同厂家的芯胶混合，因为不同厂家的芯胶配方是不一样的。橡胶中有很多种复配剂，其中一些会发生相互作用。在同一厂家的配方中，不会出现有不良反应的配合剂。然而，不同厂家的配方却大不相同。

　　Here we do not recommend Jinao conveyor belt mixed with different manufacturers of core rubber, because different manufacturers of core rubber formula is different. There are many kinds of compounds in rubber, some of which interact with each other. In the same manufacturer's formulation, there will be no adverse reactions of the formulation. However, the recipes of different manufacturers are quite different.

　　三、其他一些施工单位一般不提倡使用密封剂，这是为什么呢?

　　Third, some other construction units generally do not advocate the use of sealants, which is why?

　　金瓯输送带认为密封胶的作用主要是将两端硫化在一起，还能防止水等有害介质的侵入，防止清扫车损坏接头。

　　Jinou conveyor belt believes that the main function of sealant is to vulcanize the two ends together, but also to prevent the invasion of harmful media such as water, to prevent the sweeper from damaging the joints.

　　因此，要使硫化接头的使用寿命与带体同步，延长带体的使用寿命必须使用密封剂。

　　Therefore, in order to synchronize the service life of vulcanized joints with the belt body, sealant must be used to prolong the service life of the belt body.

　　此外，使用密封胶做硫化接头会增加成本，也会提高橡胶接头的难度，所以一些施工单位不会提倡使用密封胶。事实上，这对输送带的使用寿命产生了负面影响。

　　In addition, the use of sealants as vulcanized joints will increase costs, but also increase the difficulty of rubber joints, so some construction units will not advocate the use of sealants. In fact, this has a negative impact on the service life of the conveyor belt.
