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. 粘度和強度

　　1. Viscosity and strength

　　粘度越高，強度越高菌菇。強度通常是指砂漿凝固后的物理性能指標(biāo)笔骏，粘度通常是指砂漿攪拌后的狀態(tài)，是施工過程中的一個指標(biāo)哈寂。粘度不一定與強度有關(guān)残昔。

　　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)強度和抗壓強度

　　2. Bond strength and compressive strength

　　粘結(jié)強度是指砂漿對底層的附著力佑茴。有兩種抗剪強度和抗拉強度物即。抗拉強度是指砂漿表面抗垂直作用于表面的拉力;抗剪強度是通過施加平行力來測量的強度键闺。

　　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.

　　抗壓強度是指施加壓力所確定的砂漿破壞的值砾脑，一般為砂漿的內(nèi)聚強度。高粘結(jié)強度不一定高抗壓強度艾杏，低抗壓強度不一定低粘結(jié)強度韧衣。

　　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

　　3. Waterproof

　　防水防水概念主要在膩子產(chǎn)品中，防水指的是材料在水環(huán)境中的性能不發(fā)生很大變化购桑，防水指的是水不能滲透畅铭。膩子只是在調(diào)平材料前刷上涂料，無應(yīng)無防水材料性能勃蜘。JG158《建筑室內(nèi)用膩子》和JG157《建筑外墻用膩子》標(biāo)準(zhǔn)只規(guī)定了膩子的耐水性硕噩。觀察膩子成型后在水中浸泡一定時間后，膩子層有無變化缭贡。而實際應(yīng)用過程中有些企業(yè)夸大宣傳炉擅，說自己生產(chǎn)的膩子是防水的，而有些使用單位經(jīng)常詢問外墻膩子是否防水阳惹。

　　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)定的能力谍失。冬季通常指圍護結(jié)構(gòu)(包括屋頂、外墻琢播、門窗等)铝比，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)溫度茄颈。隔熱是砌體材料或產(chǎn)品在夏季防止熱量進入并保持室溫穩(wěn)定的能力穷筒。通常指的是封閉的能力，隔離輻射熱的影響去柿，從太陽和高溫室外在夏季弦撤，從而保持其內(nèi)部表面在一個適當(dāng)?shù)臏囟绕б弧Ｎ覈ㄖ苄гO(shè)計規(guī)范對不同地區(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)不同的傳熱過程鼠基。保溫是指冬季的傳熱過程曼舟。它通常被認(rèn)為是穩(wěn)定的傳熱，也考慮了不穩(wěn)定傳熱的一些影響聚伤。隔熱是指夏季的傳熱過程嗤积，通常在24小時周期內(nèi)周期性地進行傳熱考慮。

　　(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)評價指標(biāo)不同坠天。隔熱性能通常用傳熱系數(shù)或傳熱阻力來評價夯秃。在夏季(即炎熱天氣)，隔熱性能通常是通過計算室外溫度條件下圍護結(jié)構(gòu)內(nèi)表面的溫度來評估的痢艺。若圍護結(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)表面溫度仓洼，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)施工措施不同堤舒。由于保溫性能主要取決于圍護結(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,易受太陽輻射和室內(nèi)外溫度波動的影響色建，內(nèi)表面溫度升高，因此隔熱性能往往較差舌缤。

　　(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.
