📚 表达句精选¶
🎯 事实描述类¶
-
Talc is remarkably efficient at helping fruit to grow and stay healthy.
滑石在帮助水果生长和保持健康方面极为高效。
-
Just like people, fruit can get sunburned.
就像人一样，水果也会被晒伤。
-
Fruit-flavoured chewing gum is slightly acidic and would react with the calcium carbonate.
水果味口香糖略带酸性，会与碳酸钙发生反应。
-
In the factory, talc is also used to dust the gum base pellets and to stop sticking during the packing process.
滑石也被用于给胶基颗粒除粉，防止在包装过程中粘连。
🧠 逻辑连接¶
-
The true versatility of this mineral is nowhere better displayed than in its use in certain niche markets.
这种矿物真正的多功能性在某些利基市场中体现得最为充分。
-
On the other hand, talc makes an ideal filler because it’s non-reactive chemically.
而滑石是理想的填充剂，因为它在化学上不活跃。
🔍 立场评价 / 替代优劣¶
-
Talc is inert and non-abrasive, and does not affect the flavour, colour or chemical composition.
滑石具有惰性和非磨蚀性，不会影响风味、颜色或化学成分。
-
Talc appears to reduce the incidence of fungus on fruit and is seen as a useful alternative to chemical sprays.
滑石似乎能减少真菌发生率，被视为化学喷剂的有益替代品。
🧾 可引用例证¶
- 橄榄油行业：使用滑石吸收乳化剂，提升油产量，提高1-3%，每1%可增收$40,000（中等厂商）
- 口香糖制造：使用滑石作为填充剂，避免与酸反应，比碳酸钙更安全
- 农业防晒：滑石用于水果防晒，替代高耗水喷雾，减少晒伤，提升果实外观与口感
- Invelop Maximum SPF：美国市场商品化应用，试验中将日灼率降低60%
