從原理來看，砂紙打磨的方法對于雨刮片橡膠條老化所造成的清潔效果降低情況很好用，因此當(dāng)我們發(fā)現(xiàn)雨刮器刮不干凈玻璃時(shí)，首先要判斷其原因。如果是雨刮器在使用時(shí)發(fā)抖、異響，有可能是安裝過緊或者雨刮臂的位置和角度有問題，這時(shí)需要去專業(yè)的店里進(jìn)行調(diào)整。
From a principle perspective, the sandpaper polishing method is effective in reducing the cleaning effect caused by the aging of the rubber strip of the wiper blade. Therefore, when we find that the wiper cannot clean the glass, we should first determine the cause. If the wipers tremble or make abnormal noises during use, it is possible that they are installed too tightly or there is an issue with the position and angle of the wiper arms. In this case, it is necessary to go to a professional store for adjustment.
如果雨刮片膠皮表面出現(xiàn)嚴(yán)重?fù)p壞老化，甚至開裂等情況，這時(shí)候必須更換雨刮片。
If the surface of the wiper blade rubber is severely damaged, aged, or even cracked, it is necessary to replace the wiper blade at this time.
如果外觀沒有問題，但是雨刮片的上下總有一些部位刮不到，這時(shí)需要檢查是不是雨刮已經(jīng)變形，上下端翹起來，不能完全貼合在玻璃上，如果變形嚴(yán)重則需要更換。
If there is no problem with the appearance, but there are always some parts of the wiper blade that cannot be scraped, it is necessary to check if the wiper has deformed, the upper and lower ends are warped, and cannot fully fit on the glass. If the deformation is severe, it needs to be replaced.
當(dāng)然如果以上三點(diǎn)都不屬于，那我們就確定為雨刮片可能由于腐蝕老化造成工作效果退化，雖然可以正常使用，但是清潔效果已經(jīng)大打折扣。我們也通過這幾點(diǎn)來尋找符合要求的測試車輛。
Of course, if none of the above three points belong, then we determine that the wiper blades may have degraded their working performance due to corrosion and aging. Although they can be used normally, their cleaning effect has been greatly reduced. We also use these points to find test vehicles that meet the requirements.
2：確定測試車輛
2: Determine test vehicle
首先我們從同事中搜集了幾臺(tái)反應(yīng)雨刮片不好用的車，通過實(shí)驗(yàn)發(fā)現(xiàn)這些車多多少少都遇到了一些雨刮片的問題。
Firstly, we collected several cars from our colleagues who reported that the wiper blades were not working properly. Through experiments, we found that these cars encountered some problems with the wiper blades to some extent.
通過觀察測試車輛的現(xiàn)象，其中一臺(tái)雨刮的工作效果確實(shí)不太好，雖然沒有異響和明顯的變形和老化，但是刮完后玻璃上會(huì)殘留比較明顯的印記，符合我們的測試要求，今天的測試就從它開始。
By observing the phenomenon of the test vehicle, it was found that one of the wipers did not work well. Although there were no abnormal noises, obvious deformation or aging, there were still obvious marks on the glass after scraping, which met our testing requirements. Today's test will start from it.
3：購買工具
3: Purchase Tools
其實(shí)這個(gè)小竅門需要用到的工具非常簡單，清水一瓶，砂紙一張。這里需要說一句，市面上砂紙分為很多種，粗細(xì)程度也不一樣，這里建議用細(xì)砂紙進(jìn)行雨刮翻新，避免粗砂紙對表層傷害過度，反而會(huì)影響雨刮片的使用。
In fact, the tools required for this tip are very simple, one bottle of water and one piece of sandpaper. It should be noted that there are many types of sandpaper available on the market, with varying degrees of thickness. It is recommended to use fine sandpaper for wiper refurbishment to avoid excessive damage to the surface caused by coarse sandpaper, which can actually affect the use of wiper blades.
