呔鈴修補DIY分享(簡短版)


(English version at the bottom)

香港鋪頭做呔鈴修補好似唔多.. (可能我唔係點留意, 但freelance 既都唔少.). 有唔少人問我有冇做呔鈴修補. 我自己就從未做過呢樣野, 搞到我又想玩下, 所以就自己買左啲料試下..... 

手工點都肯定差啲, 因為我冇機器整. 只係靠對手用紗紙係咁磨, 磨番平個位之後再補. 補完之後再上色


 對於未試過補鈴既車主, 如果想補既話, 您就要預埋改色, 或者重新嘖過同一隻色啦. 因為日子耐左您條鈴原先既色會變的. 就算噴番同一隻色都會有色差.  

如果鈴邊位多個地方都需要修補的話, 好有可能要好長時間先搞得點. 因為仲要填番個位. 


不過就唔好搵我補啦, 因為我又唔似得其他做左咁多年既師傅補得咁靚, 有機會有少少突左啲補既位出黎. (除非您唔介意拎黎俾我玩). 

如果冇街出, 不妨可以自己試玩下. *最好拆左條呔出黎用砂紙磨, 就手啲. 所以如果您有打算想自己整, 您又咁岩又會換呔個陣您就可以順便搞埋.


下次會試下噴色, 到時再分享下.

There are not many retail stores prvoide repair rim service. (or maybe I am not aware of it since I do not provide such service, but I am aware that there are some freelancers who provide such service). More ppl asking such service, and out of curiosity, I decide to try it out myself.

Surely not as great as those professional. I do not have any devices to help, only using sand paper


For people who have never patronize a store for rim repair service, there is a high possibility of a need to change the color of the rim (or simply "renew" the rim by spraying the same color) as the color may change after long service hours.

It may take a long time too if there are multiple places to repair.

But please do not look for me to get this service as I am just a first timer trying this for fun. (unless you do not mind letting me "playing" around with your rim.

If you have no places to go, why not trying it out yourself? *It's easier to rub the rim by dismounting the tire. If you happen to change tire, you could take the rim to rub before installation of new tire.


The next time I will try changing color of the rim.

輪胎介紹其實好難回答


今次內容幾複雜. 因為我唔係好識點樣整理番講重點. 內容係想講下點解咁難去答 "有咩呔好介紹", 同埋 "有咩呔抵玩" 呢啲差唔多既問題

---------------------------------------

"我想揀安全既呔, 咩牌子都得"

呔既性能當然係車主最關心既一樣野. 揀番啲出名既大牌子當然有信心, 但係咪代表其他所有呔都唔好呢?


其中一樣輪胎製造商係研發輪胎時會測試既野, 就係計算輪胎既咬地性能(係唔同既方向)



當輪胎失去咬地力, 您就會失去控制車既方向. 依照當時輪胎情況下, 輪胎咬地力失去之後既一剎那有機會係再番黎.

通常都會諗到係, 輪胎老化, 或者係該款輪胎性能唔夠好, 唔安全.




老化的確係失去咬地力既因素(大部分發生呢個情況都係). 但後者就唔一定.

每一款呔都有佢既咬地力既極限. 當您用多於條呔咬地力既極限, 部車就會失去控制. 至於點知自己已經去到呢個極限就有好多因素, 包括車款.

當然輪胎物料對於咬地力都好重要

但係另一方面都要知馬路上既物料係會影響到輪胎既咬地性. 因為當輪胎行駛係馬路上就會係之間產生左化學作用. 

所以您有機會有聽過, 歐洲製既呔唔岩您係香港用. 因為歐洲製既係俾番歐洲個邊既路上面用, 唔係俾香港既路上面用. 另外地區既溫度等問題都有影響.



輪胎像膠同馬路上既化學作用 (好似係叫 hydrogen bond, 我唔係好肯定. 唔會係ionic, 都唔會係convalent). 呢種既bonding 會令到輪胎粘住係路面上. 而影響到化學作用 (chemical reaction) 既常見因素如溫度, (e.g. 高溫會加快化學作用). 有時您都會聽到, 要令到條呔行到去最岩既溫度先發揮到個款呔既性能. (但過高會有反效果)

呢樣都解釋左點解唔應該係雨天渣快車. 因為路面會有一層水擋住像膠同馬路上產生既化學作用.


另外其他影響輪胎性能包括汽車配件....

所以我係答唔到"有咩呔好介紹", 同埋 "有咩呔抵玩". 如果有既話, 其實我唔駛放咁多牌子上網. 我直接賣一個牌子就夠. 

Tyre recommendation is not easy to answer

This topic is quite complicated in a way that I couldn't figure out how to summarize the points nor how to express the points clearly. The main point I want to bring out is...

it's difficult to recommend tyres model for you, especially when the question asked is 

"which brand and model is value-added / worth purchasing"

Keep reading if you are interested to know why.

---------------------------------------

"I wanted a tyre that is safe to drive, does not really matter which brand it is"

The tyre performance is the most important concern of all drivers. Choosing a famous brand is surely making one's mind better in driving. But does that imply other models are not good enough for driving?


One of the (mutual) things that all tyre manufacturers are working on with their tyres involve the calculation of tyre grip in all directions.



Once the tyre lost grip, you lose control of your car. Depending on your tyre condition, you may get the control back just right after you lost it.

Normally people would think that it is either the tyre ages or the tyre performance is not good (hence not safe to use)



While the primary is true to most of the situations, the latter may not be the case 

Each tyre has its limit and once you utilize beyond this limit,  your vehicle will start to lose control. How to tell if you reach this limit depends on a number of factors, including your vehicle type. 

Of course the materials of the tyre plays a very important role in the contact on the road.  


However, it is also important to look at the material used to create the road, in which also an attribute to the performance of the tyre because of the chemical reaction between the tyre rubber and the road.

Thats why you may have heard choosing a made in western tyres may not be suitable to you in Hong Kong as those are meant for roads in EU or the west, which may differ from the materials used in Hong Kong. And so as temperature, humidity, etc.



The material used in tyre form a bond with the road (I think it is hydrogen bond, I am not too sure. Not ionic, not convalent). The bond helps to stick your tyre on the road. Bonding is affected by common factors like temperature ( in which the higher temperature, the faster the reaction to form the bond ). Hence the reason (or point) you may have heard, to allow the tyre reach to the optimal temperature and better performance the tyre will give to you. (and too hot will destroy the bond instead)

This also explains why you should not drive fast in a rainy day or on a wet road as the water layer blocks the formation of bonding.


There are other things affect tyre performance, including your vehicle parts. 

I have no answer to "which brand / model is value-added or worth buying". Otherwise I will just sell that particular brand.
