耐油性:耐磨地面本身不具备耐油性。如果要达到良好的抗渗耐油性能,可便用HOPER液态硬化剂、混凝土密封固化剂从而使耐磨地面表层有更佳的致密性、达到良好的抗渗性,并可以提高地面的耐磨强度和光泽度。

地坪养护:
耐磨地坪完工后(视天气温度情况),用水加PVC薄膜或专用养护剂,涂敷耐磨地坪表面进行养护,防止其表面水分激烈蒸发,保障耐磨地坪强度的稳定,养护时间为七天。
施工方案:
一、初次刮除浮浆
混凝土在浇注一定时间后(具体时间因气候定)用橡皮推刀刮除水,浮浆
耐磨地坪施工工序:
**次提浆
**次撒布
整平提浆
第二次撒布材料
二次撒布材料提浆
第三次撒布材料
在气温偏高的情况下,因混凝土凝固较快也可分二次,完成撒布材料
收光作业
耐磨地坪是在基层混凝土初凝阶段,将耐磨材料均匀撒布在混凝土表面,经专业机械施工,从而使其与混凝土地面形成一个整体,完工后的地坪具有**致密性、加倍提高地坪耐磨性、抗压性、及耐冲击性,使用寿命长。
(一)、耐磨材料概述:
耐磨材料是由骨料、波兰特种水泥及颜料和外剂等经合理级配生产的。骨料为砂状,是天然矿石成分,硬度在莫氏8度以上,平均粒径为1.5mm,占总量的60%;胶结物经过处理的高标号特种水泥,基本色调有原色、灰色、铁红色、绿色等。
(二)、 施工现场,具备以下条件:
1、施工现场的照明要充分(满足夜间施工需求);
2、业主或总包方需在施工现场提供堆放材料及机器设备的仓库;
3、浇筑混凝土时,每天浇筑量800-1000m2,金刚砂施工人员6-8人,机器7-9台;
4、为避免耐磨地面施工播撒材料时污染墙面或柱面,正在装饰的墙面、柱面,需预留距地面约1.5米左右的高度,待耐磨地面完工后再继续装饰;如已经装饰好的在约1.5米左右的高度间用塑料薄膜遮盖保护;
5、如有预埋管道及机器接口,需预先做好准备:
6、业主或总包方应提前**施工现场中的杂物,确保能如期施工;
7、耐磨地坪施工时,现场班组不得交叉作业。
8、抹光完成后的地面,必须进行养护,用**专用的养护腊进行养护。
(三)、耐磨地坪施工工艺
耐磨材料撒布的时间随气候、湿度、混凝土配合比及外加剂品种性能等因素而变化。撒布过早会使耐磨材料沉入混凝土中而失去效果;撒布太晚混凝土已凝固,会失去粘结力,使耐磨材料无法与其结合而造成剥离。混凝土浇筑后3-5小时,脚踩约下陷5mm,视表面无泌水且成初凝状态则进行耐磨材料工序:
1、每平方米耐磨材料撒布量不低于5Kg/m2;
2、墙、柱、门和模板等边线处水分消失较快,宜优先撒布施工,以防因失水而降低效果;
3、首先,给抛光机装上圆盘,整体打磨混凝土表面,从周边逐渐向内收抹,起到提浆作用;
4、**次将2/3的**耐磨材料均匀撒布在混凝土表面,材料吸收混凝土中的水分,颜色变深后,即可开始**次抹平,工具采用抹光机(装圆盘),时间应撑控好,应注意不要搓抹过度;
5、紧接着,将余下1/3的**耐磨材料均匀撒布混凝土表面,施工方向与**次垂直,随后进行第二次抹平工作;抹光作业时应纵横交错进行,均匀有序,防止材料聚集。
6、**,必须用抹光机(刀片)完成进行收光,收到光亮为止。注意随着混凝土凝固时应调整刀片倾斜角度,此时地面已有一定的硬度,不易被破坏;
7、边角处需用人工抹光,收边;
8、养护:抹光完成后的地面,必须进行养护。应在地坪完成6-12小时内用**专用养护腊进行养护。
9、为防止不规则龟裂,耐磨地坪完工2天后应切切割缝,切割缝方块为4-6m (一般根据车间梁柱距离而定),为使切割缝整齐顺直,应先统一弹线,切割深度应是地坪厚度的1/3,切割缝由土建完成,填缝材料用弹性胶或弹性树脂。
(四)、 成品保护:后续各工种、工序应妥善保护完工地面
1、严禁在成品地面上拌和材料污染到地面,影响质量;
2、完工后的金刚砂地面需洒水养护一周;
3、水电安装施工应严禁铁架铁梯、钢管材料、风管材料等,破坏成品地面,尤其地面仍处养护期内时;
4、梁柱底板粉刷涂料时,应铺放遮盖物,严禁到处洒落;
Oil resistance: Wearresisting itself does not have oil resistance. If you want to achieve good impermeability oil resistance, can you use HOPER liquid hardener, concrete sealer so that the wear surface of the ground have a better density, to achieve good impermeability, and abrasion resistance can be improved ground and gloss.
Corrosion aggregate standard salt corrosion test., 42 d of natural telecommunications always positive, stable value + 0.5 mm (SCE), the maximum value of + 120MV (SCE) cement test specimen, 5% NACI
Solution soak, 2 years and 3 months, no rust.
Floor conservation:
Wear-resistant floor after completion (depending on weather temperatures), water and PVC film or special curing agent, coating wear-resistant floor surface maintenance, prevent rapid evaporation of surface moisture, protect the stability of wear-resistant floor strength, curing time seven days.
Construction program:
First, the initial curettage laitance
Pouring concrete at a certain time (the time due to climate may be) scraping with a rubber knife to push the water, floating pulp
Wear-resistant floor construction process:
The first mention pulp
First spreader
Leveling mention pulp
Second spreading material
Secondary mention slurry spreading material
Third spreading material
In the case of high temperatures, because the rapid solidification of concrete can be divided into secondary, complete spreading material
Received light work
Wear-resistant floor at the grassroots level concrete initial setting stage, the wear-resistant material evenly spreading the concrete surface, the professional mechanical construction, making it the concrete floor form a whole, after the completion of an efficient dense floor, doubling to Ping wear resistance, resistance to stress, and impact resistance, and long service life.
(A), wear-resistant material Overview:
Wear-resistant material is made of aggregate, cement and pigments and Polish special outside agent, after reasonable grading of production. Aggregate is sand-like, natural mineral ingredients, Mohs hardness of more than 8 degrees, the average particle diameter of 1.5mm, accounting for 60% of the total; cement processing through high-grade special cement, basic colors have color, gray, iron red, green and so on.
(B), the construction site, with the following conditions:
1, the construction site lighting should be sufficient (to meet the construction needs of the night);
2, the owner or general contractor must provide stacking materials and equipment warehouse at the construction site;
3, when the pouring of concrete pouring daily volume 800-1000m2, construction workers Emery 6-8, 7-9 sets of machines;
4, in order to avoid the wear-resistant surface construction material contamination spreading or cylindrical walls being decorated walls, cylindrical, to be reserved from the ground about 1.5 meters height, wear-resistant surface to be completed before proceeding decoration; as It has a good decoration at a height of about 1.5 meters between the plastic film covering protection;
5, if the embedded pipes and machine interface, you need to prepare in advance:
6, the owner or the total package in advance to clear the construction site of debris, to ensure the construction schedule;
7, wear-resistant floor construction, site work team may not cross.
8, wiping the floor after completion of the light must be conservation, conservation with special conservation of the Royal Prince.
(Iii), wear-resistant floor construction process
Wear-resistant materials strewn time with climate, humidity, concrete mix and admixtures performance factors. Spreading premature wear-resistant materials will lose the effect of sinking concrete; concrete has solidified spreading too late, lose adhesion, abrasion-resistant material so that its binding and can not be caused by the release. 3-5 hours after the concrete pouring, foot subsidence of about 5mm, depending on the surface without bleeding into the initial setting state and wear-resistant materials is carried out the steps of:
1, per square meter of wear-resistant material spreading of not less than 5Kg / m2;
2, sideline water walls, columns, doors and templates disappear quickly, should give priority to spreading construction, to prevent water loss and reducing effect;
3, first, to the polishing machine mounted on the disc, overall polished concrete surface, wipe gradually inward from the periphery, the role played mention pulp;
4, the first two-thirds of the Royal resistant materials evenly spreading the concrete surface, the concrete material absorbs moisture, after darken, you can start the first smooth, tool use trowel (loaded disk ), the time should hold good control, you should be careful not to rub the wipe over;
5, followed by the Royal resistant materials remaining 1/3 evenly spreading the concrete surface, construction and the first vertical direction, followed by a second smooth work; trowel work should be criss-crossing, uniform and orderly, prevent material accumulation.
6. Finally, you must use the trowel (blade) completion of received light, bright received so far. Note that when the concrete has set as adjust blade angle, this time the ground has a certain hardness, not easy to be destroyed;
7, the corners need to use artificial trowel, income side;
8, conservation: ground trowel after completion, must be conserved. Floor should be completed within 6-12 hours conservation with special conservation of the Royal Prince.
9, in order to prevent irregular cracks, wear-resistant floor two days after completion should honestly kerf, cutting sewing squares of 4-6m (generally based on the beams from the workshop may be), in order to cut straight seams and edges should be unified elastic line, cutting depth should be 1/3 the thickness of the floor, cut the seam is completed by the civil, caulking material elastic rubber or elastic resin.
(D), product protection: Follow all types of work, the process should be completed properly protected ground
1, is prohibited in the finished floor mixing material contamination to the ground, affecting the quality;
2, emery ground sprinkler maintenance required after the completion of the week;
3, installation of water should be prohibited formwork construction ladder, pipe materials, duct materials, sabotage finished ground, especially when the ground is still curing period;
4, floor beams when paint coatings, should placement covering forbidden spilled everywhere;
