At present, Shandong GRC components are very popular in the market, many people will feel very puzzled when they see this product. Can this European component decorate Chinese villa buildings? Actually, it can, because it has strong plasticity and can be made into many shapes. Which way is such a good product made? Next, let's have a look with GRC component manufacturers!

構件是由水泥砂漿和耐堿玻璃纖維組成的復合材料，還含有外加劑和添加劑。它通常由水泥、纖維、聚合物、添加劑和其他材料組成。快硬硫鋁酸鹽水泥、低堿度硫鋁酸鹽水泥、普通硅酸鹽水泥和白色硅酸鹽水泥是常用的水泥品種。構件材料中使用的纖維需要是耐堿玻璃纖維。

The component is a composite material composed of cement mortar and alkali resistant glass fiber, and also contains additives and additives. It usually consists of cement, fibers, polymers, additives and other materials. Fast setting sulphoaluminate cement, low alkalinity sulphoaluminate cement, ordinary portland cement and white portland cement are commonly used. The fiber used in component materials should be alkali resistant glass fiber.

一、山東GRC構件主要通過兩種方式制造：

1、 Shandong GRC components are mainly manufactured in two ways

1、噴射法：用手工或機械方法將纖維和漿料同時噴涂到模具上，可用于制作農業構件、桶、幕墻、通風管道和模板等。

1. Spray method: the fiber and slurry are sprayed on the mold by hand or mechanical method at the same time, which can be used to make agricultural components, barrels, curtain walls, ventilation pipes and templates, etc.
              

2、預拌法：纖維和漿體預拌好后，澆在模具上，一般是振動。可用于制作擋陽板、種植盆、變電站房、接線盒、排水組件等。

2. Premixed method: after the fiber and slurry are premixed, they are poured on the mold, usually vibrating. It can be used to make sun blocking board, planting pot, substation room, junction box, drainage components, etc.

GRC采用噴射法制造時，水泥砂漿和切割好的AR-玻璃纖維同時從噴頭噴射到合適的模具上。水泥砂漿由可調泵送入噴槍，通過壓縮空氣分散成顆粒。將增強玻璃纖維粗紗喂入噴頭并切割成預定的長度，從而將短切原絲噴入分散的砂漿中，從而在模具上形成均勻的纖維砂漿層。

When GrC is made by spray method, cement mortar and cut ar glass fiber are sprayed from the nozzle to the appropriate mold at the same time. The cement mortar is sent into the spray gun by an adjustable pump and dispersed into particles by compressed air. The reinforced glass fiber roving is fed into the nozzle and cut into a predetermined length, so that the chopped strand is sprayed into the dispersed mortar to form a uniform fiber mortar layer on the mold.

二、山東GRC構件有幾種噴射法?

2、 How many spray methods are there for GRC components in Shandong?

1.手動噴射法：操作者直接將料流噴涂在模具表面，直到達到一定厚度。通過壓輥使料層和模具的形狀完全一致，水泥砂漿滲入纖維中排除空氣，使料層達到要求的密實度。

1. Manual spray method: the operator directly spray the material flow on the surface of the mold until it reaches a certain thickness. The shape of the material layer and the mold is completely consistent through the pressure roller, and the cement mortar infiltrates into the fiber to eliminate the air, so that the material layer can reach the required compactness.

2.機械噴射法：主要用于生產扁平或淺的產品。當模具在輥道或水平傳送帶上前進時，它會通過一個配備有噴頭的橫向移動系統。纖維水泥砂漿混合物可以噴涂到模具上。

2. Mechanical jet method: mainly used to produce flat or shallow products. As the die moves on the roller table or horizontal conveyor belt, it passes through a lateral movement system equipped with nozzles. The fiber cement mortar mixture can be sprayed onto the mold.

3.噴射脫水法：機械噴射法可以制備出連續的GRC材料層，然后脫水形成具有一定塑性的板坯。

3. Spray dehydration: continuous GRC material layer can be prepared by mechanical spray method, and then dehydrated to form slab with certain plasticity.

預拌法是將水泥、砂、水和添加劑與短切增強纖維原砂在攪拌機中混合，然后成型。要制作好的漿料，既有必要的和易性，又能使纖維均勻分散在其中;其次，將纖維混合到漿料中。根據成型方法的不同，預混工藝可分為預混澆注工藝和預混噴涂工藝。預拌澆筑工藝類似于預制混凝土產品，澆筑過程中常補充振動工藝。

Premixing method is to mix cement, sand, water and additives with chopped fiber reinforced raw sand in a mixer, and then form. First of all, a good size should be made, which not only has the necessary workability, but also can make the fibers evenly dispersed in it; secondly, the fibers should be mixed into the size. According to the different molding methods, the premixed process can be divided into premixed pouring process and premixed spraying process. The ready mixed pouring process is similar to the precast concrete product, and the vibration process is often supplemented in the pouring process.
