外墻保溫必看：濟(jì)南抹面砂漿與粘結(jié)砂漿的核心區(qū)別，別再混用了！

　　External wall insulation must see: the core difference between Jinan plastering mortar and bonding mortar, don't mix them up anymore!

　　在墻面尤其是外墻保溫施工中，抹面砂漿和粘結(jié)砂漿是兩種高頻使用的材料，但很多人會把它們混淆，甚至誤用，不僅影響施工效果，還可能導(dǎo)致外墻保溫系統(tǒng)開裂、脫落等隱患。其實(shí)兩者的定位、成分、性能和用途有著明確差異，作為專業(yè)抹面砂漿生產(chǎn)廠家，今天就從外墻保溫場景出發(fā)，幫大家有效理清這兩種砂漿的區(qū)別，避免踩坑。

　　In the construction of wall insulation, especially for exterior walls, plastering mortar and bonding mortar are two frequently used materials. However, many people confuse or even misuse them, which not only affects the construction effect but may also lead to hidden dangers such as cracking and detachment of the exterior wall insulation system. In fact, there are clear differences in the positioning, composition, performance, and use of the two types of mortar. As a professional manufacturer of plastering mortar, today we will start from the exterior wall insulation scene to help everyone thoroughly clarify the differences between these two types of mortar and avoid pitfalls.

　　先從核心用途說起，這是區(qū)分兩者的首要標(biāo)志。抹面砂漿的核心作用是“找平與保護(hù)”，在外部保溫系統(tǒng)中，它主要用于保溫板表面的處理——一方面能填補(bǔ)保溫板表面的微小凹凸，讓基層達(dá)到平整狀態(tài)，為后續(xù)外墻裝飾（如刷涂料、貼瓷磚）打下基礎(chǔ)；另一方面能在保溫板外層形成防護(hù)層，隔絕外界的灰塵、雨水，保護(hù)保溫板不受侵蝕，同時還能配合耐堿網(wǎng)格布增強(qiáng)抗裂性能，防止墻面因溫度變化或外力沖擊出現(xiàn)裂縫。

　　Let's start with the core purpose, which is the primary distinguishing factor between the two. The core function of plastering mortar is "leveling and protection". In external insulation systems, it is mainly used for surface treatment of insulation boards - on the one hand, it can fill the small bumps and depressions on the surface of insulation boards, making the base layer reach a flat state, and laying the foundation for subsequent exterior wall decoration (such as painting and tiling); On the other hand, it can form a protective layer on the outer layer of the insulation board, isolating dust and rainwater from the outside, protecting the insulation board from erosion, and at the same time, it can be combined with alkali resistant mesh cloth to enhance crack resistance, preventing cracks from appearing on the wall due to temperature changes or external impact.

　　而粘結(jié)砂漿的核心用途是“粘貼與固定”，它就像“膠水”一樣，專門用于將保溫板、瓷磚等材料牢牢粘貼在墻體基層上。在外部保溫施工中，第一步往往是用粘結(jié)砂漿將保溫板粘結(jié)到建筑外墻上，它需要確保保溫板與墻體之間沒有空隙、不空鼓，即使長期暴露在風(fēng)吹雨淋的環(huán)境中，也不會出現(xiàn)脫落現(xiàn)象，是整個外墻保溫系統(tǒng)的“固定基石”。

　　The core purpose of bonding mortar is "adhesion and fixation". It is like "glue", specifically used to firmly adhere insulation boards, tiles and other materials to the wall base. In external insulation construction, the first step is often to use bonding mortar to bond the insulation board to the exterior wall of the building. It is necessary to ensure that there is no gap or hollowing between the insulation board and the wall, and even if it is exposed to wind and rain for a long time, it will not fall off. It is the "fixed cornerstone" of the entire external wall insulation system.

　　成分差異是兩者功能不同的根本原因，雖然它們都以水泥和沙為基礎(chǔ)原料，但關(guān)鍵添加成分截然不同。抹面砂漿的成分中，除了水泥（提供基礎(chǔ)強(qiáng)度）和沙（增加體積、提升穩(wěn)定性），通常會加入石灰——石灰能改善砂漿的施工性，讓砂漿更容易涂抹平整，同時提升砂漿的柔韌性，減少干燥收縮時的開裂風(fēng)險；聚合物改性劑則是“可選配置”，只有對防裂要求較高的場景才會添加，用于進(jìn)一步增強(qiáng)抗裂性和粘結(jié)力。

　　The fundamental reason for the different functions of the two is the difference in composition. Although they are both based on cement and sand as raw materials, the key added components are completely different. In addition to cement (which provides foundation strength) and sand (which increases volume and stability), lime is usually added to the composition of plastering mortar. Lime can improve the workability of mortar, make it easier to apply smoothly, and enhance its flexibility, reducing the risk of cracking during drying shrinkage; Polymer modifiers are an "optional configuration" that will only be added in scenarios with high crack resistance requirements to further enhance crack resistance and bonding strength.

　　粘結(jié)砂漿的成分則完全圍繞“強(qiáng)粘結(jié)”設(shè)計(jì)，它同樣含有水泥和沙，但幾乎不會添加石灰，反而會核心增加“聚合物改性劑”的用量——這類成分能大幅提升砂漿的粘結(jié)強(qiáng)度，確保保溫板、瓷磚等材料粘得牢、不易脫落；同時還會加入纖維素醚、乳膠粉等專用添加劑，纖維素醚能改善砂漿的保水性，避免砂漿過快干燥影響粘結(jié)效果，乳膠粉則能增強(qiáng)砂漿的柔韌性和耐候性，讓粘結(jié)層能適應(yīng)墻體輕微沉降或溫度變化，避免因剛性過強(qiáng)導(dǎo)致開裂。

　　The composition of the bonding mortar is completely designed around "strong bonding". It also contains cement and sand, but almost no lime is added. Instead, the amount of "polymer modifier" is increased, which can greatly enhance the bonding strength of the mortar, ensuring that materials such as insulation boards and tiles are firmly bonded and not easily peeled off; At the same time, special additives such as cellulose ether and latex powder will be added. Cellulose ether can improve the water retention of mortar, avoiding the influence of rapid drying on the bonding effect. Latex powder can enhance the flexibility and weather resistance of mortar, allowing the bonding layer to adapt to slight wall settlement or temperature changes, and avoiding cracking caused by excessive rigidity.

　　性能側(cè)重上，兩者的差異也十分明顯。抹面砂漿更看重“平整度”和“抗裂性”——施工后表面需光滑平整，才能讓后續(xù)裝飾層貼合緊密；同時要具備一定的抗裂能力，防止因環(huán)境變化出現(xiàn)裂縫，破壞保溫和防護(hù)效果。而粘結(jié)砂漿的核心性能是“粘結(jié)強(qiáng)度”，外墻保溫場景下，它的粘結(jié)強(qiáng)度需能承受保溫板自身重量以及風(fēng)吹、震動等外力，確保長期不脫落；此外還需具備良好的耐候性，在高溫、低溫、雨天等不同環(huán)境下，粘結(jié)性能不衰減；同時要有輕微的柔韌性，避免墻體沉降導(dǎo)致粘結(jié)層開裂。

　　In terms of performance emphasis, the difference between the two is also very obvious. The plastering mortar places more emphasis on "flatness" and "crack resistance" - the surface needs to be smooth and even after construction in order for the subsequent decorative layers to adhere closely; At the same time, it is necessary to have a certain degree of crack resistance to prevent cracks from occurring due to environmental changes, which can damage the insulation and protective effects. The core performance of bonding mortar is "bonding strength". In the scenario of external wall insulation, its bonding strength needs to be able to withstand the weight of the insulation board itself, as well as external forces such as wind and vibration, to ensure long-term adhesion; In addition, it is necessary to have good weather resistance, and the bonding performance should not deteriorate in different environments such as high temperature, low temperature, and rainy days; At the same time, it should have slight flexibility to avoid wall settlement and cracking of the bonding layer.

　　在實(shí)際外墻保溫施工中，兩者通常是“配合使用”而非“二選一”：先在建筑外墻上涂抹粘結(jié)砂漿，將保溫板合理粘貼并固定；待粘結(jié)砂漿固化后，再在保溫板表面涂抹抹面砂漿，找平的同時壓入耐堿網(wǎng)格布增強(qiáng)抗裂性；非常后待抹面砂漿干燥，即可進(jìn)行外墻裝飾。這種“粘結(jié)固定+抹面防護(hù)”的組合，才能確保外墻保溫系統(tǒng)既牢固又耐用。

　　In actual external wall insulation construction, the two are usually used in combination rather than choosing one from the other: first, apply bonding mortar on the building's external wall, accurately paste and fix the insulation board; After the bonding mortar solidifies, apply plastering mortar on the surface of the insulation board, level it, and press in alkali resistant mesh cloth to enhance crack resistance; Finally, wait for the plaster mortar to dry before proceeding with exterior wall decoration. This combination of "adhesive fixation+plaster protection" is necessary to ensure that the external wall insulation system is both firm and durable.

　　廠家專業(yè)選型建議

　　Manufacturer's professional selection suggestions

　　作為生產(chǎn)廠家，提醒大家：施工前一定要根據(jù)用途合理選型，粘貼保溫板、瓷磚就用粘結(jié)砂漿，找平保溫板表面、做防護(hù)層就用抹面砂漿，切勿混用——用抹面砂漿粘保溫板，會因粘結(jié)強(qiáng)度不足導(dǎo)致保溫板脫落；用粘結(jié)砂漿做抹面，則會因成本過高且表面平整度不佳，影響后續(xù)裝飾。同時要選擇符合國家標(biāo)準(zhǔn)的產(chǎn)品，比如抹面砂漿需符合GB/T 25181-2019，粘結(jié)砂漿需符合JC/T 992-2016《墻體保溫用膨脹聚苯乙烯板膠粘劑》，確保性能達(dá)標(biāo)，為外墻保溫系統(tǒng)的安全保駕護(hù)航。

　　As a manufacturer, we remind everyone that before construction, it is necessary to accurately select according to the purpose. When pasting insulation boards and tiles, use bonding mortar. When leveling the surface of the insulation board and making a protective layer, use plastering mortar. Do not mix them - using plastering mortar to stick insulation boards may cause the insulation board to fall off due to insufficient bonding strength; Using adhesive mortar for plastering may affect subsequent decoration due to high cost and poor surface smoothness. At the same time, products that meet national standards should be selected, such as plastering mortar that meets GB/T 25181-2019, and bonding mortar that meets JC/T 992-2016 "Adhesive for Expanded Polystyrene Boards for Wall Insulation", to ensure performance standards and safeguard the safety of external wall insulation systems.
