What elements should be considered for the general requirements of GRC components?

構(gòu)件在我們現(xiàn)在的生活中非常重要。GRC構(gòu)件一般安裝在室外，經(jīng)常暴露在風(fēng)雨中，導(dǎo)致各種情況。原因是GRC組分中的水分蒸發(fā)，影響GRC組分的強(qiáng)度。GRC構(gòu)件的一般要求應(yīng)考慮哪些要素？山東GRC構(gòu)件的制造商將通知您。

Component is very important in our present life. GRC components are generally installed outdoors and often exposed to wind and rain, resulting in various conditions. The reason is that the evaporation of water in GRC components affects the strength of GRC components. What elements should be considered for the general requirements of GRC components? The manufacturer of Shandong GRC components will inform you.

一個(gè)GRC構(gòu)件安裝完畢后，用防水涂料或油漆停止GRC構(gòu)件的維修。這主要是為了避免水分蒸發(fā)。另一方面，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，所以有必要再次停止使用；

After the installation of one GRC component, the maintenance of GRC component shall be stopped with waterproof coating or paint. This is mainly to avoid water evaporation. On the other hand, it is to prevent it from contacting with air and thus forming rust on the internal reinforcement and losing its use. Of course, the coating will be weathered after a period of time, so it is necessary to stop using again;

停止定期清潔。使用一段時(shí)間后，GRC表面會(huì)有很多污漬。我們可以用不到80的高壓水槍停止清洗，但強(qiáng)度不宜過大，否則會(huì)損壞部件。應(yīng)特別注意定期停止這一清潔要求；

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

防止陽光直射。如果是室外構(gòu)件，本聲明可能不完整，但如果是室內(nèi)GRC構(gòu)件，防止陽光直射可以很好地延長(zhǎng)其使用壽命。當(dāng)然，也需要防水涂料。

Prevent direct sunlight. If it is an outdoor component, this statement may not be complete, but if it is an indoor GRC component, its service life can be well extended by preventing direct sunlight. Of course, waterproof coating is also required.

因此，我們需要采取有效的維修方法，并適當(dāng)?shù)脑缙趶?qiáng)度，以便于脫模和搬運(yùn)，從而保證設(shè)計(jì)強(qiáng)度，并限制收縮，避免開裂。養(yǎng)護(hù)可使水泥水化正常停止，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)的開裂。為了控制水的流失，簡(jiǎn)單地說，補(bǔ)水是固化的基礎(chǔ)，加上溫度控制。

Therefore, we need to take effective maintenance methods and appropriate early strength to facilitate demoulding and handling, so as to ensure design strength, limit shrinkage and avoid cracking. Curing can stop cement hydration normally 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 put, water replenishment is the basis of solidification, plus temperature control.

脫模前后，模具通常用干凈的聚乙烯薄膜包裹，這也是為了避免GRC中水分蒸發(fā)和風(fēng)的影響，同時(shí)也為了粘附水分傳熱。

Before and after demoulding, the mold is usually wrapped with clean and high-quality polyethylene film, which is also to avoid the influence of moisture evaporation and wind in GRC, and also to adhere moisture for heat transfer.

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)過程中損壞。特別是在一些地區(qū)，要求停止對(duì)GRC構(gòu)件的加熱，使溫度保持在15℃以上。關(guān)注我們http://www.nyqaac.com，了解更多的內(nèi)容！

In addition, at the early stage of maintenance, GRC members shall have sufficient strength to prevent damage during demoulding and handling. Especially in some areas, it is required to stop heating GRC components and keep the temperature above 15 ℃. Follow us http://www.nyqaac.com , learn more!
