DRY ICE BLASTING

CLEANING TECHNOLOGY 

OF the FUTURE


技術優勢


PolarTech´s與乾冰磚相比較 的主要優點有以下五點。

1. 乾冰清洗營運成本低。
2. 乾冰清洗立即噴氣供應 
3. 乾冰清洗低設備投資。 
4. 輕穎的乾冰清洗機設計。
5. 液態 CO2在地補充容易。


1.乾冰清洗營運成本低:我們的技術要求僅連接到液態 CO2 鋼瓶、 小鋼瓶或更大的低壓槽。CO2的價格, 液態 CO2 的價格是 0.50 歐元每公斤。相比 1.10歐元 每公斤乾冰。(低約1/2市場價格)。你使用乾冰必須考慮從生產開始的大約 24 小時蒸發8%。乾冰隨著時間的增長你需要使用變得越多。清洗一天損失可達 15%。 


2.乾冰清洗立即噴氣供應:很多在市場中的乾冰清洗機器需要 m3/1.5 分鐘才能執行。PolarTech´s CO2乾冰清洗機執行清理操作將低至m3/ 0.6分鐘。


3.乾冰清洗低設備投資達到同樣的效果:PolarTech´s CO2乾冰清洗機的技術設備投資是一些乾冰清洗機供應商的1/2價格。一般備品備件是貴達 300%和交貨時程長。PolarTech´s進行所有的備品備件庫存,如果當地時間之前收到的訂單並於下單同一天出貨,乾冰清洗機器需要的軟管定期更換是屬高成本,我們的技術提供不容易磨損和撕裂的軟管可以節省更換的費用。


4.輕穎的乾冰清洗機設計:一般乾冰清洗機重達 120 公斤很難操縱。PolarTech´s乾冰清洗裝備有較輕的機型,您可以輕鬆地操作在手。我們的機器仍然是較輕的設計,操作簡便。


5.液態 CO2在地補充容易: 使用乾冰清洗機意味著它必須要計畫的操作,除非你擁有你自己乾冰製造機。液態 CO2 用完時可以在本地短時間內取得。

客戶擁有優勢

乾冰清洗減少生產停機時間,使用乾冰清洗你可以經常在操作期間清潔生產設備。這意味著沒有拆除或冷卻下來必要和隨後重新裝配。從根本上減少了生產停機時間,因此得到可觀的經濟效果。


乾冰清洗降低的人力成本,實施乾冰清洗將減少部分清潔和維修費用。這是由於更高的速度和更有效的清洗與傳統方法相比。 


乾冰清洗減少磨損和撕裂,乾冰清洗是完全非磨料也因此受清潔本體沒有受到同樣的效果從砂、 刮等研磨的表皮損害。


 乾冰清洗減少廢物處理成本,減少或甚至被淘汰掉像化學藥品和溶劑的有害物質的處置成本。我們的作業只有乾冰碰到表面蒸發和脫落的塗層要從地板上掃除。



其他好處

環境:乾冰清洗是無毒,在許多情況下,我們減少了或完全消除化學品和溶劑的使用。只有少量的廢物產生,通常不需要特別昂貴的處理。CO2 用於清洗環保再生的產品。它也不會對溫室效應有任何貢獻。

表面光潔度高: 使用乾冰清洗是一種完全乾燥的過程,CO2離開了表面無殘留物。與傳統的溶劑的表面處理方式相比效能多達 3.5 倍,表面黏著問題大大降低。凝結可能發生對薄鍍金屬部件但由加熱空氣 (PT 設備選項的一部分) 可以解決這個問題。

對材料: 乾冰清洗可以非常溫取代侵略性。在同一台機器上可以執行繁多的清理任務,只需更改設置。可清潔如電子元器件、 軟金屬,紡織品都可以用無損傷清洗的功能。像清潔模具橡膠或塑膠行業不會造成任何磨損表面上的熱處理表面。

附加應用:除了清洗各種表面/設備、 乾冰清潔可用於油漆、 塗料或鍵結過程前的表面預處理。尤其是在塑膠工業中可用於去除毛邊或脫塗層。

自動方案:乾冰清洗是一個極具潛力的市場應用,可以24/7配合機械手臂在現有的生產實施或作為一個獨立的操作設置。 

 

運作方式

Cleaning with dry ice has been used for several years. More commonly used are dry ice in pellet form or blocks using a shaving technology. Both technologies are subject to high investment costs and high running costs. These factors have so far been the obstacles for establishing themselves as a general cleaning process in the industries.

PolarTech´s patented technology is the solution to the problems above. The supply media is liquid CO2 or dry ice pellets and compressed air. The dry ice particles are accelerated in a jet of compressed air.

PolarTech´s technology is using either liquid CO2 or dry ice pellets separately or in combination of both. The snow blasting we are creating our own “dry ice particles” during the cleaning process.

Dry ice blasting is meant to supplement or replace high-pressure cleaning like water, sand, glass and plastic or even hazardous chemicals and solvents. Dry ice blasting produces no secondary waste. Since the process is completely dry and non-conductive it can be used during production meaning no dismantling and costly downtime. Even cleaning hot surfaces is not a problem.

Dry ice blasting can be used for removing coatings like adhesives, varnish, oil, grease, dust, soot, mould release agents and bitumen to name a few. The technology can be used as pretreatment of surfaces before painting.

The cleaning mechanism of dry  blasting involves 3 functions. Temperature, CO2 is – 79 celcius and therefor creating cracks on the surface material. Kinetic effect, on impact the particles will reach speeds up to 300 m/sec. Sublimation, when the dry ice particles hit a surface they expand 700 fold and thereby “blowing” of the surface material.

手動操作

The control unit has all adjustment of pressure, consumption of CO2 and pellets, operating time etc. The safety operations are separate buttons. Including are the connections for the liquid CO2, compressed air and electric connection. The liquid CO2 supply of the manual CO2 snow blasting machines is mostly supplied using CO2 cylinders with a dip tube. The compressed air supply is provided either via the house network or an external compressor. Power supply is standard 100V, 110V and 230V. The compressed air supply hose is attached using a safety coupling on the control unit as well as on the supply connection. The length of the hose is variable as individual hoses can be connected to each other. The connected hoses can reach several hundred meters if needed. The liquid CO2 supply hose is equally flexible in length and can be extended as required either through fixed pipes or flexible hoses. 

The blasting hose package connects the control unit with the blasting gun. It is comprised of a high-pressure CO2 pipe, a compressed air hose and electrical connection. The hose package can be completed in almost any length.

The blasting gun is the patented technology of PolarTech´s CO2 snow blasting process. This is where the production of CO2 snow particles takes place. The ergonomic gun design gives you a good grip for handling over long period of time.  You can operate flow of liquid CO2, air only and air + CO2. Nozzles are available either round, flat, bended or customized. The fluidic flow of all nozzles is optimized for best performance.

Wear and tear of nozzles does not occur.

                                             


自動線方案

Automated CO2 snow blasting equipment can be implemented as a continuous operation (24 / 7). By installing a control cabinet, it is possible to control and monitor one or several CO2 snow blasting nozzles. The equipment is designed and manufactured according to customer requirements.

The liquid CO2 is supplied using a low pressure tank, a booster pump and an insulated CO2 ring circuit. The compressed air supply is provided either via the house network or by external compressor. The Control Unit includes latest technology for the necessary safety components, operating controls, process controls and monitoring processes. The CO2 snow blasting nozzle can be fitted with a robotic adapter and when this interface is used, it is possible to either fix the machine securely or more flexibly, adapt it to a portal or axle robot. The liquid CO2 has a temperature of approx. -20 °C when a low pressure tank is used. Therefore all pipe lines and hose systems must be thermally insulated. The booster pump and the insulation guarantee that the CO2 is always liquid even with long supply lines. The tank content is monitored completely automatically and when necessary will be filled from a gas supplier's fuelling vehicle. This supply concept keeps operating costs low.

If the amount of CO2 used is minimal then the supply generally can be completed using either CO2 cylinders or bundles with a dip tube. Only in this case can automation be realized with manual standard equipment and an Automatic control unit.
