我們都知道鹽城固化劑地坪漆施工對(duì)基礎(chǔ)地面的要求比較高,要求基層水泥強(qiáng)度在C25以上,含水率在8%以下,無(wú)起砂起灰現(xiàn)象。但是你知道為什么無(wú)錫固化劑地坪漆施工對(duì)基面的要求這么高嗎?下面無(wú)錫固化劑地坪漆廠(chǎng)家就給大家詳細(xì)解答基層缺陷對(duì)南通固化劑地坪漆施工的影響。針對(duì)基面缺陷對(duì)無(wú)錫固化劑地坪漆施工造成的不良影響,施工前需要對(duì)基礎(chǔ)地面進(jìn)行以下處理: Epoxy we all know that the construction of epoxy floor paint requires higher requirements for the foundation floor, requiring the strength of the base cement to be above C25, moisture content below 8%, and no sand and ash phenomenon. But do you know why the construction of floor paint requires so high a base? The following epoxy floor paint manufacturers will give you a detailed answer to the impact of base defects on the construction of floor paint. In view of the adverse effects of base surface defects on the construction of epoxy floor paint, the following treatments are needed before construction: 1、 強(qiáng)度低:地坪漆行業(yè)一般要求水泥地面的壓縮強(qiáng)度要大于25MPa,如果基面的強(qiáng)度過(guò)低會(huì)導(dǎo)致無(wú)錫固化劑地坪漆施工后的地面與基層的固著不牢,車(chē)間廠(chǎng)房地面長(zhǎng)期有叉車(chē)行走,此時(shí)就會(huì)使得基層與無(wú)錫固化劑地坪地面一起拉裂。 1、 強(qiáng)度低:地坪漆行業(yè)一般要求水泥地面的壓縮強(qiáng)度要大于25MPa,如果基面的強(qiáng)度過(guò)低會(huì)導(dǎo)致無(wú)錫固化劑地坪漆施工后的地面與基層的固著不牢,車(chē)間廠(chǎng)房地面長(zhǎng)期有叉車(chē)行走,此時(shí)就會(huì)使得基層與無(wú)錫固化劑地坪地面一起拉裂。 2、 平整度:水泥地面不平整,將會(huì)影響整個(gè)無(wú)錫固化劑地坪的裝飾效果,特別對(duì)于環(huán)氧自流平地坪,地面不平整會(huì)造成涂膜厚度不均勻,影響著涂膜的性能特點(diǎn)。 2. Flatness: The unevenness of cement floor will affect the decorative effect of the whole epoxy floor. Especially for the epoxy self-leveling floor, the unevenness of the ground will cause the uneven thickness of the film and affect the performance characteristics of the film. 3、 防水、防潮:無(wú)錫固化劑地坪漆施工前要注意基層做好防水、防潮處理,不然土壤中的水分會(huì)通過(guò)水泥地面的毛細(xì)孔作用上升到面層,影響地坪漆材料與混凝土的黏結(jié),便會(huì)使得涂膜產(chǎn)生鼓泡、脫層等現(xiàn)象。 3. Waterproof and moisture-proof: Before the construction of epoxy floor paint, attention should be paid to the waterproof and moisture-proof treatment of the base layer, otherwise the moisture in the soil will rise to the surface layer through the capillary effect of the cement floor, which will affect the bonding between the floor paint material and concrete, and will cause blistering and delamination of the coating film. 4、 疏松:基層混凝土水泥地面疏松,會(huì)導(dǎo)致底漆的用量大大增加,并且在無(wú)錫固化劑地坪漆施工中存在大量的沙粒雜質(zhì),影響著施工效果,成本也會(huì)隨之增大。 4. Porosity: Loose base concrete cement floor will lead to a large increase in the amount of primer, and there are a large number of sand impurities in the construction of epoxy floor paint, which will affect the construction effect, and the cost will also increase.
針對(duì)基面缺陷對(duì)地坪漆施工造成的不良影響,施工前需要對(duì)基礎(chǔ)環(huán)氧地面進(jìn)行以下處理: In view of the adverse effect of base surface defect on floor paint construction, the following treatment should be carried out on the base epoxy floor before construction. 1、基層面上附著物的處理 1. Treatment of attachments on base surface
在基層表面上,如水泥地面,會(huì)附著施工留下的水泥疙瘩、砂粒和浮漿(水泥游離堿性結(jié)晶體)等,這些基層附著物在施涂地坪底漆之前必須用磨光機(jī)或鏟刀等施工工具清除干凈。如基層存在用瀝青填補(bǔ)的伸縮縫,必須將伸縮縫中的瀝青全部挖出,然后灌入環(huán)氧砂漿,用金屬抹刀抹至和周?chē)鶎铀健?On the surface of the base, such as the cement floor, there will be cement bumps, sand grains and floating slurry (cement free alkaline crystals) left by the construction. These base attachments must be cleaned by polishing machine or shovel knife before applying the floor primer. If there are expansion joints filled with asphalt in the base, the asphalt in the expansion joints must be digged out, then filled with epoxy mortar, and wiped with metal spatula to the level of the surrounding base. 2、油污的處理 2. Treatment of Oil Pollution
對(duì)于工業(yè)地坪,可能會(huì)受到多種油污污染,對(duì)于油污污染過(guò)的地坪,該處混凝土的毛細(xì)孔已全部被油污填充,環(huán)氧類(lèi)底漆不能滲入到混凝土中去,影響漆膜和底材的附著力,有時(shí)會(huì)引起縮孔等弊病,常用處理方法有以下幾種:對(duì)表層較少的油污,可用硬毛刷蘸清潔劑或溶劑多次清洗;嚴(yán)重污染的地坪,建議用汽油或酒精燃燒方法去除;用研磨機(jī)除去污染的混凝土層;以上方法處理的地坪仍有油污泛出的地面,建議重新做混凝土。 For industrial floor, it may be polluted by many kinds of oil pollution. For the floor polluted by oil pollution, the capillary holes of the concrete are all filled with oil pollution. Epoxy primer can not penetrate into the concrete, which affects the adhesion of the film and the base material, and sometimes causes shrinkage holes and other defects. The common treatment methods are as follows: for less oil pollution on the surface, hard brush can be used to dip in clean. It is suggested to use gasoline or alcohol burning method to remove the seriously polluted floors, and grinding machine to remove the polluted concrete layer. The floors treated by the above methods still have oil-polluted floors, so it is suggested to make concrete again. 3、平整度的處理 3. Treatment of Flatness
對(duì)于大面積的地坪的平整度要求為:3毫米誤差(2米的測(cè)量段)、合格率85%,對(duì)平整度達(dá)不到要求的地方需要修補(bǔ):用環(huán)氧砂漿或其它合適的材料對(duì)地面上的坑洞、不平整處修補(bǔ)1-3遍;用研磨機(jī)、銑刨機(jī)修整地面的平整度。 The flatness requirement for large area of the ground is: 3 mm error (2 m measurement section), 85% qualified rate. The places where the flatness can not meet the requirement need to be repaired: the holes and irregularities on the ground should be repaired 1-3 times with epoxy mortar or other suitable materials; and the flatness of the ground should be repaired with grinders and milling machines. 4、切割縫的處理 4. Treatment of Cutting Seam
先將切割縫割成“V”型,清除干凈縫內(nèi)的雜物、碎石;2用環(huán)氧砂漿填平切割縫;將兩側(cè)打磨平整一致。 Firstly, the cutting seam is cut into "V" type, and the debris and debris in the clean seam are removed; secondly, the cutting seam is filled with epoxy mortar; and the two sides are polished uniformly.
5、結(jié)構(gòu)縫的處理 5. Treatment of structural joints
先將縫兩側(cè)的松動(dòng)部分鑿掉成如下方型,目的是修補(bǔ)后的環(huán)氧砂漿部分下面有一個(gè)承重面;清除干凈縫內(nèi)的雜物、碎石;中間用PE泡沫(分兩段)填充保護(hù)后,兩邊用環(huán)氧砂漿填平;待環(huán)氧砂漿干燥后,將上面一段PE泡沫拿掉,用彈性密封膠填平;將兩側(cè)打磨平整一致。 First, the loose parts on both sides of the seam are chipped into the following square shape. The purpose is to repair the epoxy mortar part with a load-bearing surface below; remove the debris and gravel from the clean seam; fill with PE foam in two parts, and use epoxy mortar to fill the sides. After drying the epoxy mortar, remove the upper PE foam and fill it with elastic sealant. 6、裂縫的處理 6. Treatment of cracks
先將裂縫處切割成“V”型,清除干凈縫內(nèi)的雜物、碎石;用環(huán)氧砂漿或其它合適的材料填平,干燥后打磨平整。 Firstly, the cracks are cut into "V" shape, and the debris and debris in the cracks are removed. Then, the cracks are filled with epoxy mortar or other suitable materials and ground flat after drying. 7、地磚接縫的處理 7. Treatment of floor tile joints
清除接縫之間的灰塵和雜質(zhì);用環(huán)氧砂漿或其它合適的材料填平,干燥后打磨平整。 Remove dust and impurities between joints; fill with epoxy mortar or other suitable materials, and grind flat after drying.
