       安徽萘系緩凝高效減水劑

  JW-I萘系緩凝高效減水劑系以β-萘磺酸亞甲基高級縮合物以及適量緩凝、增強等組分復合而成,具有高效減水、緩凝、保坍和增強等功能。產品對水泥適應性強,摻量少,使用方便,特別適用于高效減水和緩凝要求的混凝土工程。

安徽萘系緩凝高效減水劑

  一、主要性能

  ▉本品分為粉劑和液體兩種,粉劑呈棕褐色,水劑呈棕黑色。產品性能穩定,無毒、無刺激性和放射性,不含對鋼筋有銹蝕危險的物質。

  ▉增大流動性:水泥凈漿流動度大于200mm,當混凝土配合比不變時,摻入適量高效減水劑后,可將拌合料的流動性由0~50mmt提高到150~250mm。

  ▉高效減水:按照國家規定現行標準GB8076-2008《混凝土外加劑檢測》,其減水率達18%以上,最大的可達25%

  ▉高保坍:本產品采用反應性高分子共聚物為保坍組分,其保坍能力很強,而卻對水泥品種、型號及其氣溫適應性強,幾乎不受溫度變化的影響。在氣溫低時,混凝土坍落度損失慢,反應性高分子共聚物的釋放速度慢;氣溫高時,混凝土坍落度損失加快,反應性高分子共聚物釋放速度加快,混凝土的保坍能力提高。

  ▉緩凝效果明顯。摻用本產品的混凝土,其初凝時間可延緩10h左右,這一特性為避免或減少施工裂縫提供了不少保證,也可通過調整產品配方以調整混凝土的凝結時間,確保滿足工程需求。

  ▉提高混凝土強度:在單位膠凝用量相同的條件下,其28d強度較普通混凝土一般可提高35~60%

  二、適用范圍

  產品可廣泛適用于高效減水和緩凝要求的混凝土

  三、使用方法

  ▉粉劑量為膠凝材料的0.5-1.0%,水劑為1.3-2.0%.

  ▉粉狀固體若直接使用,應與水泥一道投入拌合為切勿直接加在濕的砂、石表面;若配成溶液,則應充分溶解。

  ▉為確保混凝土土均質性,攪拌時間要延長30~60秒。

  四、包裝與貯存

  ▉粉劑采用內塑料袋外編織袋包裝,每袋凈重40公斤,水劑罐裝或協議包裝。

  ▉應在干燥環境中存放,水劑要密封,粉劑要注意防潮,避免結塊。

  ▉本品有效期三年,粉劑堆放高度不宜超過10袋。

  五、技術服務

  根據用戶和工程的需要,有時需要特定配方的JW-I緩凝高效減水劑,我公司將根據您的工程技術要求,實際使用的原材料以及工地的特定條件,做出評估分析來確定特定的配方,以帶來最佳的砼質量和最好的經濟效益。

  JW-I Naphthalene retarded sulphonate superplasticizer

  JW-I Naphthalene retarded sulphonate superplasticizer withβ- naphthalene sulfonic acid methylene senior condensate as well as the amount of slow coagulation, enhanced component compound and into, has the advantages of high efficiency water reducing, retarding, slump and enhancement functions. Products of cement adaptability, less content, easy to use, suitable and concrete engineering setting requirements on high efficiency water reducing

  The main performance

  ▉This product is divided into two kinds :powder and liquid , powder is brown, agent is brown black . Products performance is stable, non-toxic, no stimulation and radioactivity, no rust risk of reinforced material.

  ▉Increased liquidity: the fluidity of cement paste is greater than 200mm, when the retarding soil mix ratio, adding superplasticizer, the liquidity of mixture composed of 0 ~ 50mmt to 150 ~ 250mm.

  ▉High-efficient water reducing: according to the current standard GB8076-2008 "test of concrete admixture" provisions of the state, the water reducing rate of more than 18%, the largest up to 25%

  ▉High slump: This product uses reactive polymer as the slump of graves, the slump retaining ability is very strong, but the type and temperature adaptability of cement varieties, strong, nearly not affected by temperature changes. In low temperatures, the slump loss of concrete is slow, reflecting the release rate of copolymers slow; In high temperatures the concrete slump loss accelerated, reactive polymer release speed, improve the concrete slump retaining ability.

  ▉Retarding effect is obvious. Mixed with this product concrete, the initial setting time delay of about 10h, the characteristics of construction in order to avoid or reduce the gap to provide a lot of assurance, also can adjust the product formula to adjust the setting time of concrete, to ensure that meet the requirements of engineering.

  ▉Improve concrete strength: in terms of unit under the same amount of cementing material, its 28d strength is lower than ordinary concrete can be increased by 35 ~ 60%

  Scope of application

  Products can be widely applied to high efficiency water reducing and retarding and requirements of concrete.

  The use of methods

  ▉Powder content of cementitious material 0.5-1.0%, agent 1.3-2.0%

  ▉Powdered solid if direct use, should be mixed with cement an input is not directly add surface in the wet sand, stone; if the match into solution, it should be fully dissolved.

  ▉In order to ensure the concrete soil heterogeneity, stirring time should be extended from 30 to 60 seconds.

  Packaging and storage

  ▉Powder using plastic bag inside, outer woven bag, net weight 40 kg per bag, canned or agreement packaging agent.

  ▉Should be stored in dry conditions, water should be sealed, powder should pay attention to moisture, avoid caking.

  ▉This product is valid for a period of three years, powder stacking height should not be more than 10 bags.

  Technical service

  According to the needs of users and engineering, sometimes need a specific formulation of the JW-I retarding superplasticizer, our company will according to your requirements engineering technology, the specific conditions of raw materials and site, make evaluation and analysis to determine the specific formula, with the best since the concrete quality and the best economic benefit.
