這是hoya兄 跟大家分享的他開孔的好方法^^
不過此方法十分危險就是了啦
相信hoya兄在製作的過程中
一定有全身防護 良好通風 廢液收集 對吧^^
建議hoya兄在post這篇文章之前
應該要以"強烈"的字眼 寫出Hydrofluoric Acid 對身體的傷害
如何做安全防護 如何急救 及廢液的處理............
如此才不會讓不了解 HF的人死於非命喔
能做到這樣的話 這篇文章就更有保留的價值了喔^^
謝謝您的分享

HYDROFLUORIC ACID
--------------------------------------------------------------------------------
Hydrofluoric acid (HF) is a clear, colorless, fuming, corrosive liquid or gas commonly used to dissolve silica and metals in the laboratory. Improper use may cause serious injury, illness, or death. Faculty, staff and students are required to receive training prior to using hydrofluoric acid. Instruction should include identification of HF hazards, proper protective measures, and procedures for treatment in the event of exposure.
SYNONYMS

Anhydrous hydrofluoric acid Hydrofluoride Hydrogen fluoride

HEALTH EFFECTS
A poison by inhalation, ingestion, absorption, or contact. Target organs are the eyes, respiratory and digestive systems, and skin. Anhydrous HF or HF mists or vapors can cause severe respiratory-tract irritation, which may be fatal. A corrosive irritant to skin, eyes (at 0.05 mg/L), and mucous membranes; acid splashed into the eyes may cause blindness. Ingestion causes acute irritation of the digestive tract and of the esophagus. A teratogen.
Symptoms of exposure include irritation of the eyes, nose, and throat; pulmonary edema, burns of the skin and eyes; nasal congestion; bronchitis.

HANDLING/PROTECTIVE EQUIPMENT
HF attacks glass, concrete, and some metals; especially cast iron and alloys that contain silica. It also attacks such organic materials as leather, natural rubber, and wood.
Adequate ventilation is crucial. All work must be performed in a hood so that safe levels are not exceeded; i.e., less than the OSHA 8-hour Permissible Exposure Limit of 3 parts per million (ppm) and the 15 minute Short-Term Exposure Limit of 6 ppm.
All contact of the vapor or liquid with eyes, skin, respiratory , or digestive system must be avoided by using protective equipment. Wear anti-acid clothing (e.g., an acid-resistant apron), neoprene gloves, goggles and/or a face shield, and synthetic rubber shoes or boots to avoid burns and poisoning. Wearing clothing that has absorbed small amounts of HF can result in serious delayed effects such as painful, slow-healing skin ulcers. The protective equipment should be washed after each use to remove any HF. A safety shower and eyewash fountain must be readily accessible.
Contact lenses should not be worn when working with this chemical.

STORAGE
Anhydrous HF must be stored in pressure containers because of its low boiling point (19.54 C) and high vapor pressure (40 mm Hg at 2.5 C).
Although HF is nonflammable, it should not be stored or used in metallic containers or piping since aqueous solutions can cause formation of hydrogen which presents a fire and explosion hazard. Potential sources of ignition (sparks and flames) should be excluded from areas having equipment containing HF.

SPILL RESPONSE
Spills of HF must be treated immediately to minimize the dangers of vapor inhalation, body contact, corrosion of equipment, and possible generation of hazardous gases. Only properly trained personnel should cleanup spills using the procedure outlined below. If you have not received such training, evacuate the area and contact the Environmental Health and Safety Department at 1-6590.
If properly trained, contain the spill and evacuate non-essential personnel from the laboratory or area where the spill occurred. Next, using appropriate protective equipment (i.e., approved respirator, gloves, apron, and eye protection) slowly cover the contaminated surface with lime, sodium carbonate (soda ash), or sodium bicarbonate. Mix and add water to form a slurry. Check pH to determine neutrality and dispose the mixture down the drain with copious amounts of water once pH is between 5.5 and 8.5.

FIRST AID
Anyone who knows or suspects that he or she has come into direct contact with HF should immediately flush the exposed area with large quantities of cool water continuously for at least 15 minutes. Contaminated clothing should be removed as quickly as possible while flushing. Medical attention should be obtained promptly, even if the injury appears slight. On the way to the physician, the burned area should be immersed in a mixture of ice and water or, if readily available, an iced solution of benzalkonium chloride. It may be necessary to remove the area being soaked from the solution periodically to relieve discomfort caused by the cold. If immersion is impractical, a compress made by inserting ice cubes between layers of gauze should be used. Contact the Poison Center for additional assistance.
In case of contact with the eyes, immediately flush the eyes with large amounts of water, alternately lifting the lower and upper lids. Continue for at least 15 minutes. Get medical attention immediately.
Anyone who has inhaled HF vapor should be removed immediately to fresh air. If breathing has stopped, artificial respiration should be performed. Keep the affected person warm and at rest. Get medical attention as soon as possible.
Anyone who has ingested HF should drink a large quantity of water as quickly as possible. Do not induce vomiting. Again, medical help should be obtained promptly. After the acid has been diluted with water, if medical attention is delayed, the person should be given milk or 2 fluid ounces of milk of magnesia to drink in order to soothe the burning effect.

基本上.....這是 hoya 大大所提供的自身經驗,做為版主的我,並不一定要刪除此篇文章,
而且有太多人提到"危險",我想看過的人,心裡都有危機意識,做任何事之前
自身的安全,和事前的準備,是很重要的.....請各位大大DIY時,多多注意使用工具和材料
有無安全上的顧慮,多多提供一下資訊給,想嚐試的人.........^_^
 
這東西千萬別自己買來處理,就算是號稱工安最嚴謹的工廠都曾出過很令人意外
的危險致命的工安事件,在自己家中處理氫氟酸你所遵循的規範絕對比不上花大
錢管理嚴謹的工廠,

只能說一句話HF是打死都不想碰的東西,網友千萬不要去買去用....

化學這種東西你沒遇上的時候你不覺得他恐怖,出事的時候都已經太晚了
前幾天看電視National Geographic談環境賀爾蒙的節目,只因為船底塗的某
中防止貝類附著的In化合物造成貝類繁殖能力的嚴重降低,而在實驗室中
只要50公尺長的游泳池中加上幾mg的量就有影響.......
有些東西吃多了會致命,有些東西不會致命只會絕種
HF是那種會致命的東西,......
 
我覺得不要刪才好
這麼危險的東西
要是沒講清楚讓大家都去玩才危險
經過大家的討論
我想看的人都應該知道--真的危險性很高
防護雖然能降低危險
但是危險有時候只因為意外
而這意外卻足以讓你致命
希望大家謹記在心喔
幾天的薪水即可以買一個新缸子了
挖一個洞,省個幾千元
卻要用生命來冒險
真的不值得喔
 
風險太大 安全第一
我到是很好奇開出來的洞多平整.可以po一張相片看看嗎?
 
建議加註"""強烈警語""""
為了養魚養到截肢....很恐怖....站上很多年輕人....恐不妥...
 
呵呵
沒想到小弟一篇文章
引起這麼多迴響
在此
特別強調
氫氟酸真ㄉ很危險 跟其他ㄉ強酸強檢一樣都會造成極大ㄉ傷害
所以小弟在過程中
手套加三層口罩加缸子移到陽台加電風扇
並不建議輕易嘗試
小弟只是試圖找出一ㄍ方式在已成型ㄉ強化玻璃上開孔
也許有人之前作ㄉ缸子花ㄌ上萬元現在想開孔卻無計可施
不但成資源ㄉ浪費
也徒增垃圾
站在一ㄍ學理ㄉ立場上
氫氟酸的確不會對塑膠等有機聚合物作用
強化玻璃也的確無法以機械破壞
因玻璃在高溫下急速冷卻會因內應力而形成類似晶型ㄉ結構
所以一受力就像晶體破裂
一ㄍ東西危不危險其實最主要還是取決於使用者
瓦斯本無害 不慎便成災
不是嗎
提供一ㄍ可行性
破解強化玻璃絕對無法開孔ㄉ迷思
但是
極度危險
強烈建議不要嘗試 真ㄉ情非得以 請務必全副武裝
其實板主大人要刪這篇文章小弟也不反對
就讓它束之高閣 藏諸名山ㄅ
小弟ㄉ缸子已經開好孔ㄌ
至於照片 小弟就不POㄌ 以免刺激別人去嘗試
真ㄉ想看我可以mail給您嚕
最後感謝各位大大不吝給小弟惠予指正
 
回覆這ㄍ好像有點離題ㄌ
環境荷爾蒙其實到處都有
燒電線皮就有
焚化爐附近一定特別高
不但惠干擾生物體內正常ㄉ荷爾蒙造成不孕還會造成基因異變致癌
而且
環境荷爾蒙造成ㄉ影響還會”遺傳”
這是工業化國家ㄉ宿命
 
人人都有選擇的自由,
你也有,別人也有,
只是了解的人對於較不熟悉的人有告知的責任,
尤其是有些明顯可以預防跟挽救的事故上,
車子跑的快,很好用很方便,只要你有駕照你就能開,
不過一年死在交通事故的人數遠多於飛機失事(不
論是比例或是件數),
車子可以開不過告知駕駛人風險所在是一種預防,
That's all.

工業化國家ㄉ另一個宿命,
過度以為人定勝天,
最終免不了被吞噬,
 
謝謝大大的分享.雖然很危險.但卻是一個好方法.
沒萬全準備還是不要輕易嘗試
 
20020905一直到20070921再次被推出來研讀五年了..........guudiu 大大還真用心...也讓我見習瞭解該文章的學問....
 
各位大大~如果是我..看完之後絕對不會去用,太危險了...嚇死人,但我還是建議移除這篇..原因是,如果有不法之人拿去用...會很多人...........移除+1
