干粉砂漿已被廣泛應(yīng)用，但在應(yīng)用過(guò)程中一些生產(chǎn)、使用和監(jiān)督的概念和性能指標(biāo)混淆，今天濟(jì)南抹面砂漿小編為大家分析一下主要的概念如下:
Dry powder mortar has been widely used, but in the process of application, some concepts of production, use and supervision are confused with performance indicators. Today, Jinan plastering mortar Co., Ltd. analyzes the main concepts as follows:
1. 粘度和強(qiáng)度
1. Viscosity and strength
粘度越高，強(qiáng)度越高。強(qiáng)度通常是指砂漿凝固后的物理性能指標(biāo)，粘度通常是指砂漿攪拌后的狀態(tài)，是施工過(guò)程中的一個(gè)指標(biāo)。粘度不一定與強(qiáng)度有關(guān)。
The higher the viscosity, the higher the strength. Strength usually refers to the physical performance index of mortar after solidification, and viscosity usually refers to the state of mortar after mixing, which is an index in the construction process. Viscosity is not necessarily related to strength.
2、粘結(jié)強(qiáng)度和抗壓強(qiáng)度
2. Bond strength and compressive strength
粘結(jié)強(qiáng)度是指砂漿對(duì)底層的附著力。有兩種抗剪強(qiáng)度和抗拉強(qiáng)度?？估瓘?qiáng)度是指砂漿表面抗垂直作用于表面的拉力;抗剪強(qiáng)度是通過(guò)施加平行力來(lái)測(cè)量的強(qiáng)度。
Bond strength refers to the maximum adhesion of mortar to the bottom layer. There are two kinds of shear strength and tensile strength. The tensile strength refers to the resistance of mortar surface to the tensile force acting vertically on the surface; the shear strength refers to the strength measured by applying parallel force.
抗壓強(qiáng)度是指施加壓力所確定的砂漿破壞的值，一般為砂漿的內(nèi)聚強(qiáng)度。高粘結(jié)強(qiáng)度不一定高抗壓強(qiáng)度，低抗壓強(qiáng)度不一定低粘結(jié)強(qiáng)度。
Compressive strength refers to the maximum value of mortar failure determined by the applied pressure, which is generally the cohesive strength of mortar. High bond strength is not necessarily high compressive strength, low compressive strength is not necessarily low bond strength.
3.防水防水

The concept of waterproof is mainly used in putty products. Waterproof refers to that the performance of materials in water environment does not change greatly, and waterproof refers to that water cannot penetrate. The putty is only applied with paint before leveling the material, and there shall be no waterproof material performance. JG158 putty for interior building and jg157 putty for exterior wall of building only stipulate the water resistance of putty. Observe whether the putty layer changes after soaking in water for a certain time. In the process of practical application, some enterprises exaggerate their propaganda, saying that the putty they produce is waterproof, while some users often ask whether the putty on the outer wall is waterproof.
4. 保溫隔熱
4. Thermal insulation
隔熱是砌體材料或產(chǎn)品在冬季防止熱量損失和保持室溫穩(wěn)定的能力。冬季通常指圍護(hù)結(jié)構(gòu)(包括屋頂、外墻、門(mén)窗等)，以防止熱量從室內(nèi)轉(zhuǎn)移到室外，從而保持適當(dāng)?shù)氖覂?nèi)溫度。隔熱是砌體材料或產(chǎn)品在夏季防止熱量進(jìn)入并保持室溫穩(wěn)定的能力。通常指的是封閉的能力，隔離輻射熱的影響，從太陽(yáng)和高溫室外在夏季，從而保持其內(nèi)部表面在一個(gè)適當(dāng)?shù)臏囟取Ｎ覈?guó)建筑能效設(shè)計(jì)規(guī)范對(duì)不同地區(qū)建筑能效指標(biāo)的規(guī)定不同，如下表所示:
Heat insulation is the ability of masonry materials or products to prevent heat loss and maintain room temperature stability in winter. Winter usually refers to enclosure (including roof, exterior wall, doors and windows, etc.) to prevent heat transfer from indoor to outdoor, so as to maintain appropriate indoor temperature. Heat insulation is the ability of masonry materials or products to prevent heat from entering and keep room temperature stable in summer. Usually refers to the ability to close, isolate the effects of radiant heat from the sun and high temperature outdoors in summer, thus maintaining its internal surface at an appropriate temperature. China's building energy efficiency design code has different regulations on building energy efficiency indicators in different regions, as shown in the table below:
保溫與隔熱的區(qū)別:
Difference between heat preservation and heat insulation:
(1)不同的傳熱過(guò)程。保溫是指冬季的傳熱過(guò)程。它通常被認(rèn)為是穩(wěn)定的傳熱，也考慮了不穩(wěn)定傳熱的一些影響。隔熱是指夏季的傳熱過(guò)程，通常在24小時(shí)周期內(nèi)周期性地進(jìn)行傳熱考慮。
(1) different heat transfer processes. Heat preservation refers to the heat transfer process in winter. It is generally considered as stable heat transfer, and some effects of unstable heat transfer are also considered. Heat insulation refers to the heat transfer process in summer, which is usually considered periodically in a 24-hour period.
(2)評(píng)價(jià)指標(biāo)不同。隔熱性能通常用傳熱系數(shù)或傳熱阻力來(lái)評(píng)價(jià)。在夏季(即炎熱天氣)，隔熱性能通常是通過(guò)計(jì)算室外溫度條件下圍護(hù)結(jié)構(gòu)內(nèi)表面的溫度來(lái)評(píng)估的。若圍護(hù)結(jié)構(gòu)內(nèi)表面溫度低于或等于相同條件下240mm厚磚墻(即磚墻)內(nèi)表面溫度，則認(rèn)為滿足保溫要求。
(2) different evaluation indexes. Thermal insulation performance is usually evaluated by heat transfer coefficient or heat transfer resistance. In summer (i.e. hot weather), the thermal insulation performance is usually evaluated by calculating the maximum temperature of the inner surface of the enclosure under outdoor temperature conditions. If the maximum temperature of the inner surface of the enclosure is lower than or equal to the maximum temperature of the inner surface of 240mm thick brick wall (i.e. brick wall) under the same conditions, the insulation requirements shall be considered to be met.
(3)施工措施不同。由于保溫性能主要取決于圍護(hù)結(jié)構(gòu)的傳熱系數(shù)和傳熱阻力的大小,由多孔輕質(zhì)保溫材料輕型圍護(hù)結(jié)構(gòu)的傳熱系數(shù)小,傳熱阻力較大,因此,保溫性能好,但由于其重量輕,熱穩(wěn)定性較差,易受太陽(yáng)輻射和室內(nèi)外溫度波動(dòng)的影響，內(nèi)表面溫度升高，因此隔熱性能往往較差。
(3) different construction measures. Because the thermal insulation performance mainly depends on the heat transfer coefficient and heat transfer resistance of the enclosure, the heat transfer coefficient of the light-weight enclosure made of porous lightweight thermal insulation material is small and the heat transfer resistance is large, so the thermal insulation performance is good, but because of its light weight and poor thermal stability, it is easy to be affected by solar radiation and indoor and outdoor temperature fluctuations, and the internal surface temperature rises, so the thermal insulation performance is often poor.
