Combined with the hot data of the entire network in the past 10 days, this article will provide you with structured answers from the dimensions of industry trends, butter types, performance comparisons and purchasing suggestions.
1. Related data of hot topics across the entire network (last 10 days)
| keywords | search index | Main discussion platform | Hotspot related events |
|---|---|---|---|
| Construction machinery maintenance | 18,742 | Baidu/Zhihu | Extreme weather triggers heated discussion on equipment maintenance |
| Lithium grease butter | 9,856 | Station B/Douyin | Technology blogger’s comparison and evaluation video goes viral |
| Excavator maintenance | 15,309 | Kuaishou/Tieba | Equipment failures occur frequently during the spring start-up season |
2. Comparison of core parameters of special butter for excavators
| type | Applicable temperature | water resistance | Wear resistance | Mainstream brands |
|---|---|---|---|---|
| Calcium based lipid | -10℃~60℃ | generally | ★★★ | Great Wall/Kunlun |
| Lithium grease | -30℃~120℃ | excellent | ★★★★★ | Mobil/Shell |
| Compound aluminum base grease | -40℃~150℃ | Excellent | ★★★★ | Total/Castrol |
3. In-depth analysis of hot issues
1.Why has lithium-based grease become the focus recently?Actual measurements by Douyin technology celebrity "Mechanical Master" show that after 30 hours of continuous operation, lithium-based grease reduces pin wear by 47% compared to calcium-based grease. The related video has received more than 500,000 likes.
2.How to choose butter in extreme weather?According to data from the China Construction Machinery Association, 25% of lubrication failures occurred in Northeast China due to low temperatures in February. Composite aluminum-based grease still maintains good pumpability in a -35°C environment.
3.Consumer misunderstandings:Baidu Index shows that the search volume for the misconception "the thicker the butter, the better" dropped by 38% year-on-year, indicating that professional science popularization is effective.
4. Purchasing suggestions (organized based on hot topic feedback)
1.Normal working conditions:Choose NLGI level 2 lithium-based grease, which is the most cost-effective (market price is about 25-40 yuan/kg)
2.Rainy/Underwater Operations:It is recommended to use waterproof butter with PTFE additives, such as Shell Gadus S2 V220
3.Ultra-low temperature environment:Choose synthetic hydrocarbon-based grease, the freezing point can reach -50℃ (such as Kunlun FH-SO low-temperature grease)
5. Observation of Industry Trends
Tmall data shows that sales of construction machinery grease increased by 63% year-on-year in February 2024, of which biodegradable products grew by 210%. As environmental protection policies tighten, green lubricants that comply with GB/T 31469 standards will become a new hot spot.
