## 重点判断方向

### 建筑腻子批刮末端黏刀、返刀重

比较末端黏刀、返刀轻重和收刀状态，同时复核针孔、开裂、打磨、粘结和耐水后状态。
- 产品：[福大四方®建筑腻子用 5010 羟丙基甲基纤维素醚 HPMC](https://www.88800666.com/products/building-putty-5010-hpmc/)
- 应用：[建筑腻子与墙面找平应用场景](https://www.88800666.com/applications/putty-powder/)
- 判断方法：[室内耐水腻子用 HPMC，为什么不能只看黏度？](https://www.88800666.com/technical-column/building-putty-cellulose-ether-selection/)

### 自流平砂浆泌水和经时流动度

固定胶凝材料、级配、用水和搅拌条件，比较防泌水、流动阻力、经时状态、针孔和强度。
- 产品：[福大四方®流动性砂浆用低粘羟丙基甲基纤维素醚 HPMC](https://www.88800666.com/products/self-leveling-hpmc-400/)
- 应用：[水泥基自流平砂浆](https://www.88800666.com/applications/self-leveling-mortar/)
- 判断方法：[水泥基自流平砂浆，防泌水与经时流动怎样一起看？](https://www.88800666.com/technical-column/self-leveling-bleeding-flow-retention/)

### 砂浆施工轻便与强度保持

施工轻便与湿密度、抗压、拉伸粘结、收面和复购稳定一起判断，不只比较含气或短时手感。
- 产品：[福大四方®砂浆增塑剂](https://www.88800666.com/products/plaster-mortar-plasticizer/)
- 应用：[干粉砂浆应用场景](https://www.88800666.com/applications/dry-mix-mortar/)
- 判断方法：[普通抹灰砂浆比较增塑与引气路线，为什么要同时看密度？](https://www.88800666.com/technical-column/plaster-mortar-plasticizer-jgt-426/)

### 干粉砂浆纤维分散与抗裂

先按裂缝出现时间和位置分类，再比较纤维长度、分散、露纤、施工状态、强度和粘结。
- 产品：[福大四方®干粉砂浆用合成纤维](https://www.88800666.com/products/dry-mortar-synthetic-fiber/)
- 应用：[保温系统抗裂砂浆](https://www.88800666.com/applications/crack-resistant-mortar/)
- 判断方法：[保温系统抗裂砂浆的合成纤维，怎样判断长度组合是否值得采用？](https://www.88800666.com/technical-column/dry-mortar-synthetic-fiber-length-grading/)

### 防火涂料开裂与炭层完整性

比较纤维分散、施工厚度、干燥裂纹与粘结；膨胀型还要观察炭层完整性。耐火性能按涂料类型、完整配方和规定试验确认。
- 产品：[福大四方®防火涂料用合成纤维](https://www.88800666.com/products/fireproof-coating-synthetic-fiber/)
- 应用：[钢结构防火涂料](https://www.88800666.com/applications/steel-fireproof-coating/)
- 判断方法：[非膨胀型钢结构防火涂料加纤维，怎样判断裂纹控制是否有效？](https://www.88800666.com/technical-column/steel-fireproof-coating-synthetic-fiber-char-layer/)

### SMA 纤维用量、油石比和分散

用同一矿料、级配和沥青条件比较析漏、分散、油石比、马歇尔指标和路用性能，不由单一纤维承诺工程结果。
- 产品：[福大四方®SMA 沥青路面用合成纤维](https://www.88800666.com/products/sma-asphalt-synthetic-fiber/)
- 应用：[SMA 沥青路面](https://www.88800666.com/applications/sma-asphalt/)
- 判断方法：[SMA 合成纤维想降掺，怎样判断性能与成本？](https://www.88800666.com/technical-column/sma-synthetic-fiber-dosage-reduction-test/)
