配件用俩月就变脆，雾化忽大忽小。雾化器配件回料掺多了，脆的根子在源头。
结论先摆：雾化器配件，耐化学防脆绑一起
雾化器配件是“接触药雾”的件：耐化学、防脆、密封。材料要耐化学、韧性好、密封——结论先给：雾化器配件用医用级 SEBS 基 TPE 是主流；高温药液，硅胶或 TPV 留。
雾化器配件最大的坑：料脆不脆，回料占比说了算。回料占比高，料就脆——回料，是脆的根源。
雾化器配件是功能件：发脆、开裂都是问题。材料选对，雾化才稳——功能件，别省料钱。
TPE凭啥不脆：耐化学可做，韧性可加
雾化器配件用 TPE 的理由：耐化学可做、韧性可做、密封可做、效率高——四条合起来，适合配件。
耐化学是核心：接触药雾。耐化学测试写进验收——溶胀，就是问题。
韧性不能省：回料掺多了，弯折几次就发白开裂。回料占比写进验收——回料，是脆的根源。
吸一天吹它：药雾、加热、密封
药雾工况：接触药液。耐化学数据要验——溶胀，就是问题。
温度工况：雾化加热。耐温数据要验——变形，就是问题。
密封工况：配件密封。密封测试要验——漏雾，就是问题。
TPE还是硅胶：配件上看黄不黄
| 维度 | TPE | 硅胶 |
|---|
| 耐化学 | 可做 | 好 |
| 韧性 | 可做 | 好 |
| 回料风险 | 需控 | 低 |
| 成本 | 中 | 中高 |
| 效率 | 注塑 | 硫化 |
| 批次 | 稳 | 稳 |
表格读法：硅胶耐化学好但贵、硫化慢；TPE 性价比高——常规配件 TPE，高温药液硅胶。
按药液温度选：高温硅胶，常规 TPE。
回料排查表：源头原包优先
| 项目 | 方法 | 异常提示 |
|---|
| 回料占比 | 供应商声明 | 高则脆 |
| 韧性 | 冲击测试 | 低则脆 |
| 颜色 | 对比色卡 | 暗则疑回料 |
| 批次 | 追溯记录 | 无则疑回料 |
表格读法：回料占比、熔指、冲击四项排下来，脆料现原形。
回料，是脆的根源。
两个坑：回料冒充、耐化学造假
坑一：回料冒充。新料包装里掺回料，弯折测试一上就露馅——回料占比必问。
坑二：耐化学虚标。报告写耐化学，实际溶胀——耐化学按实测验收。
坑三：烘料漏做。受潮发脆——烘料对照，必做。
验收三问：变脆、透明度、批次
三问：回料占比多少、耐化学按什么药液、烘料按什么条件。一验：实际雾化实测——三问一验，供应商底细清楚。
回料验证要先行：先问清回料比例和来源，再谈价格——回料，是脆的根源。
留样要成习惯：每批留样，耐化学韧性按批次复测。批次换料先对比再放量——批次稳，客诉少。
雾化器配件尺寸精度影响雾化效果——尺寸公差波动大，雾化就不稳。透明配件对杂质色点敏感，透明度批次一致性单独验收。
配件选型，尺寸精度和透明度一起验。
配件用几个月变脆发黄——耐化学档位不够，消毒液和药液把材料侵蚀了。按实际清洁消毒方式做测试。
变脆不是用旧了，是材料扛不住化学侵蚀。
回料占比高的料批次不稳定——原包料优先，源头清楚了回料风险才低。采购时问清原料来源，别只看价格。
回料占比说了算，批次稳不稳看源头。
把工作温度和清洁消毒方式告诉供应商——带加热功能的雾化器，药液温度偏高。按实际温度选料，按消毒方式推荐配方。
温度和清洁方式说清，配方才对路。
雾化器配件是“小而精的件”——尺寸精度高，透明度要求高，化学兼容性要求高。三样一起顾，材料选不对就出问题。小配件的账，一点都不小。
雾化器配件常见问题与对策表
| 现象 | 原因 | 对策 |
|---|
| 发脆 | 回料占比高 | 查回料 |
| 溶胀 | 药雾腐蚀 | 换耐化学料 |
| 变形 | 加热温度高 | 换耐温料 |
| 漏雾 | 密封不足 | 调配合 |
| 透明度差 | 杂质 | 换纯净料 |
雾化器配件耐温按 60℃ 热水循环 100 次验收，不变形不析出。 雾化片周边密封要软，外壳要挺——同一件软硬两段料，双色注塑模具要调温度。

Accessories become brittle after just two months, and atomization fluctuates between big and small. Too much recycled material in atomizer parts causes brittleness at the source.
Conclusion first: atomizer accessories are chemical-resistant and anti-brittle, bundled together
Nebulizer accessories are "contact medicinal mist" parts: chemical-resistant, anti-brittle, sealed. Materials must be chemical-resistant, tough, and sealed—conclusion first: medical-grade SEBS-based TPE is mainstream for atomizer accessories; High-temperature chemicals, silicone gel, or TPV are retained.
The biggest pitfall of atomizer parts: whether the material is brittle or not depends on the proportion of recycled material. High recycled material means the material is brittle—recycled material is the root of brittleness.
Nebulizer accessories are functional parts: brittleness and cracking are problems. Choosing the right materials ensures atomization is stable—functional parts, don't skimp on material costs. Why not
TPE brittle: chemical resistance can be made, toughness can be added
Reasons for using TPE for atomizer parts: chemical resistance can be made, toughness can be made, sealing can be made, efficiency is high — all four together are suitable for parts.
Chemical resistance is the core: contact with chemical mist. Chemical resistance test is written into acceptance — swelling is the problem.
Toughness cannot be compromised: too much recycled material will cause white and crack after a few bendings. Return material ratio is written into acceptance — return material is the root cause of brittleness.
Breathe for a day: Medicinal mist, heating, sealing
Medicinal mist working condition: Contact with chemical liquid. Chemical resistance data must be checked—swelling is the problem.
Temperature condition: Atomization and heating. Temperature resistance data must be tested—deformation is the problem.
Sealing condition: Accessory sealing. Sealing test must be checked—mist leakage is the problem.
TPE or silicone: Check the parts for yellow or not
| dimensions | TPE | silicone |
|---|
| chemical resistance | can be made | good |
| toughness | workable | good |
| Refill Material Risk | Requirement Control | Low |
| Cost | Medium | Medium High |
| Efficiency | Injection Molding | Vulcanization |
| Batch | Stable | Stable |
Table Reading: Silicone is chemically resistant but expensive, vulcanization slow; TPE offers high cost-performance ratio—regular accessories TPE, high-temperature medicated silicone.
Select by chemical temperature: high-temperature silicone, conventional TPE
Return Material Inspection Table: Original Source Priority
| Project | Method | Abnormal Notification |
|---|
| Recycled Material Proportion | Supplier Declaration | High Brittle |
| Toughness | Impact Test | Low Brittle Material |
| Color | Contrast color card | Dark Suspected Recycled Material |
| Batch | Traceability Record | No Suspected Recycled Material |
Table Reading: Return material ratio, melting index, and impact are listed together, revealing the original form of the brittle material.
Recycled material is the root cause of brittleness.
Two pitfalls: recycled material passed off, chemical resistance falsification
Pitfall One: recycled material passed off. Mixed material into new packaging, bending test immediately reveals the truth—recycled material proportion must be asked.
Pitfall 2: Chemical resistance false labeling. The report says chemical resistance, but actual swelling is used—chemical resistance is accepted based on actual tests.
Pitfall 3: Drying material is missed. Moisture and brittleness—Dried material is a must.
Acceptance question 3: brittleness, transparency, batch size
Question 3: What is the proportion of recycled material, chemical resistance according to chemical solution, drying material under what conditions. First inspection: Actual atomization testing—three questions and one inspection, supplier details are clear.
Return material verification must come first: first ask about the return material ratio and source, then discuss the price—return material is the root cause of brittleness.
Make it a habit to retain samples: keep samples for each batch, and retest chemical toughness by batch. Compare batch material changes before scaling up—batch stability, fewer customer complaints.
Atomizer component dimensional accuracy affects atomization results—large dimensional tolerances cause unstable atomization. Transparent parts are sensitive to impurity color spots; batch consistency for transparency is accepted separately.
Component selection: check dimensional accuracy and transparency together.
Parts become brittle and yellow after a few months—insufficient chemical resistance, disinfectants and chemicals have eroded the material. Test according to actual cleaning and disinfection methods.
Brittleness isn't because it's old, it's because the material can't withstand chemical corrosion.
Batches with high recycled material are unstable—prioritizing original packaging material, knowing the source reduces the risk of recycling. When purchasing, ask about the source of raw materials; don't just look at price.
Tell the supplier the proportion of recycled material; whether the batch is stable depends on the source.
Tell the supplier the working temperature and cleaning and disinfection method—for atomizers with heating functions, the chemical solution temperature is too high. Select materials based on actual temperature, and recommend formulas based on disinfection methods.
Explain temperature and cleaning methods clearly, and only then will the formula be appropriate
Atomizer accessories are 'small but refined components'—they require high dimensional accuracy, high transparency, and high chemical compatibility. Considering all three together, if the material selection is wrong, problems arise. The costs of small accessories are not small at all.
Table of Common Problems and Countermeasures for Atomizer Accessories
| Phenomenon | Reason | Countermeasure |
|---|
| becoming crispy | High proportion of recycled material | Retrieve return material |
| Swelling | Drug mist corrosion | Change to chemical-resistant material |
| Transformation | High heating temperature | Change to heat-resistant material |
| leakage fog | Insufficient sealing | coordination |
| Poor transparency | Impurity | Change to pure material |
Atomizer accessories should withstand 60℃ hot water circulation tested 100 times for acceptance, without deformation or precipitation. The edge seal of the atomizing sheet must be soft, and the shell should be firm — the same piece has two sections with different hardness, and the temperature of the two-color injection mold needs to be adjusted.
Cologne client case: High rework rate of coating delamination, reproduce tactile feel during production debugging
A medical device factory in Jiaxing was experiencing mass delamination of coated parts for atomizer accessories, with a persistently high rework rate. Kolon cooperated on-site to follow the production and adjust until the yield stabilized, the tactile rebound matched the benchmark samples, and the delamination disappeared. During production adjustment, the delamination was locked down before mass production—coating is the art of temperature.
Summary
When selecting atomizer accessories, first ask about the recycled material, then test chemical resistance. Whether the material is brittle depends on the proportion of recycled material—don't let the recycled material take the blame.
