自流平砂漿施工期間的重要事項

來源：http://www.wavc.cn 日期：2023-03-18 發布人：

自流平砂漿是一種干混型粉狀材料，由多種活性成分組成，硬化速度快、流動性好。主要組成部分有普硅水泥、高鋁水泥、硅酸鹽水泥、活性酵母激發劑等。下面來講講濟南自流平砂漿施工期間的重要事項吧。

Self leveling mortar is a dry mixed powder material composed of a variety of active ingredients, with fast hardening speed and good fluidity. The main components include ordinary silicon cement, high alumina cement, Portland cement, active yeast activator, etc. Let's talk about important issues during the construction of Jinan self-leveling mortar.

（1）保證施工器具清潔，不能混入其他材料攪拌，應嚴格控制材料與水的比例，石膏基自流平砂漿：水=1:0.35~0.40，充分攪拌漿料使內部精料分散均勻，保證石膏基自流平砂漿流動性的同時不造成漿體離析。

(1) Ensure that the construction equipment is clean and cannot be mixed with other materials for mixing. The ratio of materials to water should be strictly controlled. Gypsum based self-leveling mortar: water=1:0.35-0.40. Fully mix the slurry to evenly disperse the internal fine materials, ensuring the fluidity of gypsum based self-leveling mortar without causing slurry segregation.

（2）基層含水率應＜8%，含水率較大會影響界面劑成膜，且后期水汽蒸發降低石膏基自流平砂漿粘結力，待界面劑成膜干燥后再進行施工。

(2) The moisture content of the base layer should be less than 8%. A large moisture content will affect the film formation of the interfacial agent, and the later water vapor evaporation will reduce the adhesive force of the stone plaster based self-leveling mortar. The construction can be carried out after the film formation of the interfacial agent is dried.

（3）應根據場地情況、施工情況、施工厚度等設置好分區線，分區線內的區域應在初凝時間內澆筑完畢，未連續澆筑將形成接茬，影響整體平整度。

(3) Zoning lines should be set according to site conditions, construction conditions, construction thickness, etc. The areas within the zoning line should be poured within the initial setting time. Discontinuous pouring will form joints and affect the overall flatness.

（4）自流平石膏攪拌后應在30min內使用完畢，超過操作時間砂漿流動性會急劇下降，失去操作性。

(4) After mixing, the self-leveling gypsum should be used within 30 minutes. After the operation time, the fluidity of the mortar will decrease sharply and the operability will be lost.

（5）已澆筑完成的禁止再次調整，未澆筑平整的自流平砂漿應在干燥后進行界面處理后再進行下一層澆筑。

(5) It is prohibited to adjust the poured mortar again. The self-leveling mortar that has not been poured and leveled should be dried and undergo interface treatment before pouring the next layer.

（6）澆筑前建議做界面處理，以降低基層吸水率，基層吸水后會造成喪失流動性，蜂窩、鼓泡等現象。

(6) Before pouring, interface treatment must be carried out to reduce the water absorption rate of the base layer. After the base layer absorbs water, it may cause loss of fluidity, honeycomb, blistering, and other phenomena.

（7）施工完成后，避免擾動，不能有穿堂風，以免造成局部過早干燥；夏季炎熱溫度較高時，宜選擇夜間進行施工；在寒冷的情況下，使用溫水（水溫不超過35℃）攪拌。

(7) After construction is completed, avoid disturbance and avoid ventilation to avoid premature drying of parts; When the summer is hot and the temperature is high, it is advisable to choose night construction; In cold conditions, stir with warm water (water temperature not exceeding 35 ℃).

（8）若下一工序與石膏基自流平砂漿接觸面為水泥基產品，應在石膏基自流平砂漿干燥后，做表面封閉處理；有機類飾面層不能施工于石膏基自流平砂漿上。

(8) If the contact surface between the next process and the gypsum based self-leveling mortar is a cement based product, the surface shall be sealed after the gypsum based self-leveling mortar is dried; Organic finishing layers cannot be applied to gypsum based self-leveling mortar.

（9）石膏基自流平砂漿干燥后（含水率≤1.0%）才能進行下一工序施工，需保證抹灰石膏含水率低于8%，否則會造成下一工序粘結力降低。

(9) The gypsum based self-leveling mortar can only be constructed in the next process after drying (moisture content ≤ 1.0%). It is necessary to ensure that the moisture content of the plastering gypsum is lower than 8%, otherwise the adhesive force in the next process will be reduced.

（10）新攪拌的漿體與已經過了操作時間的漿體，嚴禁混合攪拌，避免產生操作時間急劇縮短、開裂等現象，做到每次攪拌的料使用干凈。

(10) It is strictly prohibited to mix the newly stirred slurry with the slurry that has passed the operation time, to avoid sharp shortening of the operation time, cracking, and other phenomena, and to ensure that the material used for each mixing is clean.

（11）石膏基自流平砂漿施工厚度應≥5mm，厚度過薄將影響石膏基自流平砂漿的流平性，影響石膏基自流平砂漿的水化硬化，降低成品的終強度。

(11) The construction thickness of gypsum based self-leveling mortar should be ≥ 5mm. If the thickness is too thin, it will affect the leveling property of gypsum based self-leveling mortar, affect the hydration and hardening of gypsum based self-leveling mortar, and reduce the final strength of the finished product.

自流平砂漿用途廣泛，可以用于工業廠房、車間、倉儲、商業賣場、體育館、醫院、辦公室等；也可以用于居家等。它既可以作為飾面面層，也可以作為耐磨基層。您有相關需求就來我們網站http://www.wavc.cn咨詢吧！
