GRC component is very important in our life. GRC components are usually installed outdoors and exposed to wind and rain, which leads to a variety of bad situations. The reason is that the evaporation of water in GRC affects the strength of GRC components. What factors should be considered for the general requirements of GRC components? The GRC component manufacturer will tell you.

一個(gè)GRC構(gòu)件安裝完畢后，用防水涂料或油漆用于構(gòu)件的保養(yǎng)。這主要是為了避免水分蒸發(fā)。另一方面，也是為了防止與空氣接觸，從而在內(nèi)部鋼筋上形成鐵銹而失去使用。當(dāng)然，涂層在一段時(shí)間后會(huì)被風(fēng)化，所以有必要再次涂刷。

After a GRC component is installed, waterproof coating or paint is used for component maintenance. This is mainly to avoid water evaporation. On the other hand, it is also to prevent contact with the air, so as to form rust on the internal reinforcement and lose use. Of course, the coating will be weathered after a period of time, so it is necessary to brush again.

要定期清潔。使用一段時(shí)間后，這種構(gòu)件的表面會(huì)有很多污漬。我們可以用不到80壓力的高壓水槍來(lái)清洗，但強(qiáng)度不宜過(guò)大，否則會(huì)損壞部件。應(yīng)特別注意定期清潔這一要求;

Clean regularly. After a period of use, there will be a lot of stains on the surface of this component. We can use the high pressure water gun with less than 80 pressure to clean, but the strength should not be too high, otherwise the parts will be damaged. Special attention should be paid to the requirement of regular cleaning;
                 

防止陽(yáng)光直接照射。如果是室外GRC組件，一定要做好相應(yīng)的防曬措施，比如實(shí)施遮蓋或者涂刷相應(yīng)的防曬物質(zhì)，防止陽(yáng)光直射可以很好地延長(zhǎng)其使用壽命。當(dāng)然，但如果是室內(nèi)GRC組件，也需要防水涂料。

Prevent direct sunlight. If it is outdoor GRC components, it is necessary to take corresponding sunscreen measures, such as covering or brushing the corresponding sunscreen material, to prevent direct sunlight, which can well extend its service life. Of course, but if it is indoor GRC components, also need waterproof coating.

因此，我們需要采取有效的維修方法，并適當(dāng)?shù)募哟髲?qiáng)度，以便于脫模和搬運(yùn)，從而設(shè)計(jì)強(qiáng)度，并限制收縮，避免開(kāi)裂。養(yǎng)護(hù)可使水泥化停止，增強(qiáng)強(qiáng)度和粘結(jié)性。它需要在很大程度上減少體積損失、收縮和可能出現(xiàn)的開(kāi)裂。為了控制水的流失，簡(jiǎn)單地說(shuō)，補(bǔ)水是固化的基礎(chǔ)，同時(shí)加上溫度的控制。脫模前后，模具通常用干凈質(zhì)量好的聚乙烯薄膜包裹，這也是為了避免GRC中水分蒸發(fā)和風(fēng)的影響，同時(shí)也為了粘附水分與傳熱。此外，在維護(hù)的早期階段，GRC構(gòu)件應(yīng)具有足夠的強(qiáng)度，以防止在脫模和搬運(yùn)過(guò)程中損壞。特別是在一些地區(qū)，要求停止對(duì)GRC組件的加熱，使溫度保持在15℃以上。

Therefore, we need to take effective maintenance methods and increase the strength appropriately to facilitate demoulding and handling, so as to design the strength, limit the shrinkage and avoid cracking. Curing can stop cementation and enhance strength and cohesiveness. It needs to greatly reduce volume loss, shrinkage and possible cracking. In order to control the loss of water, simply speaking, make-up water is the basis of solidification, and temperature control is also added. Before and after demoulding, the mold is usually wrapped with clean and good quality polyethylene film, which is also to avoid the influence of moisture evaporation and wind in GRC, and also to adhere moisture and heat transfer. In addition, at the early stage of maintenance, GRC members should have sufficient strength to prevent damage during demoulding and handling. Especially in some areas, it is required to stop heating GRC components to keep the temperature above 15 ℃.

GRC構(gòu)件具有強(qiáng)度高、韌性大、吸收率低、綠色、不易褪色、成本低、重量輕等特點(diǎn)。與主體建筑具有同等的服務(wù)壽命。對(duì)美化建筑環(huán)境做出了巨大貢獻(xiàn)，成為建筑企業(yè)界非常流行的裝飾材料。

GRC components have the characteristics of high strength, high toughness, low absorption rate, green environmental protection, not easy to fade, low cost, light weight and so on. It has the same service life as the main building. It has made a great contribution to beautify the building environment and has become a very popular decoration material in the construction industry.
