在室內裝修材料選擇中，環保性能已成為消費者關注的核心指標。膩子粉與硅藻泥作為墻面基層處理與裝飾的常用材料，其環保性差異需從原料構成、生產流程、使用場景及健康影響等多維度進行綜合評估。

　　In the selection of indoor decoration materials, environmental performance has become a core indicator of consumer concern. Putty powder and diatomaceous earth are commonly used materials for wall base treatment and decoration, and their environmental differences need to be comprehensively evaluated from multiple dimensions such as raw material composition, production process, usage scenarios, and health impacts.

　　原料成分是環保性的基礎決定因素。傳統膩子粉以碳酸鈣、滑石粉等無機礦物粉料為主體，添加纖維素醚、淀粉醚等天然或改性植物膠作為粘結劑，部分產品會加入灰鈣粉提升硬度。這類配方中，重金屬含量通常低于國家強制標準，但低端產品可能因使用劣質膠粉導致甲醛殘留。硅藻泥則以硅藻土為核心原料，其多孔結構賦予材料調節濕度的功能，但需配合石英砂、粘土及化學助劑改善施工性能。值得注意的是，部分硅藻泥產品為提升粘結力會添加白水泥或石膏，可能引入微量放射性物質，需通過權威檢測確保氡濃度達標。

　　The composition of raw materials is the fundamental determinant of environmental friendliness. Traditional putty powder is mainly composed of inorganic mineral powders such as calcium carbonate and talcum powder, with the addition of natural or modified plant adhesives such as cellulose ether and starch ether as binders. Some products also add calcium ash powder to enhance hardness. In this type of formula, the heavy metal content is usually lower than the national mandatory standard, but low-end products may have residual formaldehyde due to the use of inferior rubber powder. Diatomaceous earth is the core material of diatomaceous earth, and its porous structure endows the material with the function of regulating humidity, but it needs to be combined with quartz sand, clay, and chemical additives to improve construction performance. It is worth noting that some diatomaceous earth products may add white cement or gypsum to enhance adhesion, which may introduce trace amounts of radioactive substances. Authoritative testing is required to ensure that radon concentration meets the standard.

　　生產環節的環保控制直接影響最終產品的綠色屬性。正規膩子粉工廠采用全封閉自動化生產線，粉塵排放通過布袋除塵器處理，廢水經沉淀池循環利用，但小型作坊可能因工藝落后造成揚塵污染。硅藻泥生產對原料研磨精度要求更高，能耗較普通膩子粉生產增加約20%，但部分企業通過余熱回收技術降低能耗。兩類材料在烘干環節均存在能源消耗差異，電加熱與天然氣烘干對碳排放的影響需納入環保評估體系。

　　The environmental control in the production process directly affects the green attributes of the final product. Legitimate putty powder factories adopt fully enclosed automated production lines, with dust emissions treated through bag filters and wastewater recycled through sedimentation tanks. However, small workshops may cause dust pollution due to outdated processes. The production of diatomaceous earth requires higher grinding accuracy for raw materials, and the energy consumption is about 20% higher than that of ordinary putty powder production. However, some enterprises reduce energy consumption through waste heat recovery technology. There is a difference in energy consumption between the two types of materials in the drying process, and the impact of electric heating and natural gas drying on carbon emissions needs to be included in the environmental assessment system.

　　使用階段的健康風險是消費者最直接的關切點。膩子粉施工需與膠水混合，劣質膠水中的甲醛釋放周期可達3-15年，成為室內空氣污染主要來源。而硅藻泥采用干粉兌水攪拌，施工過程無需添加有機溶劑，理論上可避免VOC釋放。但硅藻泥的多孔結構可能吸附空氣中的游離甲醛，需關注其分解能力——僅添加光觸媒或納米二氧化鈦的產品才具備持續凈化功能，普通硅藻泥僅起物理吸附作用。

　　The health risks during the usage phase are the most direct concern for consumers. Putty powder construction needs to be mixed with glue, and the formaldehyde release cycle in inferior glue can reach 3-15 years, becoming the main source of indoor air pollution. Diatom mud is mixed with dry powder and water, and there is no need to add organic solvents during the construction process, theoretically avoiding VOC emissions. However, the porous structure of diatomaceous earth may adsorb free formaldehyde in the air, and its decomposition ability needs to be considered - only products with added photocatalysts or nano titanium dioxide have continuous purification function, while ordinary diatomaceous earth only has physical adsorption effect.

　　功能特性帶來的環境效益不容忽視。硅藻泥的調濕性能可將室內濕度維持在40%-70%的舒適區間，減少空調除濕能耗，經測算可使建筑整體節能率提升8%-12%。其呼吸功能還能緩解墻面結露現象，延長裝修壽命。膩子粉雖不具備主動調濕能力，但現代產品通過添加竹炭、海泡石等成分，也可實現一定的甲醛吸附功能，且耐水膩子在潮濕環境中的穩定性優于普通硅藻泥。

　　The environmental benefits brought by functional features cannot be ignored. The moisture regulating performance of diatomaceous earth can maintain indoor humidity within a comfortable range of 40% -70%, reduce air conditioning dehumidification energy consumption, and is estimated to increase the overall energy efficiency of buildings by 8% -12%. Its respiratory function can also alleviate wall condensation and extend the lifespan of decoration. Although putty powder does not have the ability to actively adjust humidity, modern products can also achieve a certain formaldehyde adsorption function by adding components such as bamboo charcoal and sepiolite, and the stability of water-resistant putty in humid environments is better than that of ordinary diatomaceous earth.

　　全生命周期的環保性評估需考慮材料可回收性。膩子粉作為基層材料，翻新時需完全鏟除，產生建筑垃圾，但部分企業已開發可降解型產品，廢棄物經破碎后可用作路基填料。硅藻泥墻面翻新可局部修補，減少材料浪費，且硅藻土本身為天然礦物，廢棄后不會對土壤造成污染。

　　The environmental assessment of the entire lifecycle should consider the recyclability of materials. Putty powder, as a base material, needs to be completely removed during renovation, generating construction waste. However, some companies have developed biodegradable products, and the waste can be used as roadbed filling after being crushed. The renovation of diatomaceous earth walls can be partially repaired to reduce material waste, and diatomaceous earth itself is a natural mineral that will not cause soil pollution after disposal.
