低压锅炉水控制剂 LP BOILER WATER CONTROL
LP BOILER WATER CONTROL
低压锅炉水控制剂
(专用于低压锅炉)
说明
这种专门的锅炉水处理剂是为适应简便处理锅炉水的需要而设计生产的。由
于“马力达”低压锅炉水控制剂为液态，故在使用前无需溶解干粉剂。本剂
不像干粉剂那样会因潮湿而凝结或硬化，故没有储存方面的困难。本剂将磷
酸盐、碱和沉淀物处理剂结合于一体，又具有很强的可溶性，故易于使用。
用途
使用“马力达”低压锅炉水控制剂，可以在化学反应上控制形成水垢的矿物
质；在物理反应上控制形成盐的粘度；并通过保持必要的PH值，控制锅炉
金属的腐蚀现象。
在锅炉水蒸发时，从锅炉内释放出许多晶体微粒。如果任其发展，晶体微粒
即会粘附于金属表面，并相互粘沾从而形成水垢。使用“马力达”低压锅炉
水控制剂，可以防止晶体微粒产生并粘附于锅炉表面。随后，用清炉的方法
除去这种经处理并已沉淀的形成水垢的矿物质。
剂量
低压锅炉水控制剂最初剂量应根据水的硬度而定。使硬度保持在零度所需的
剂量约为每半吨（125加仑）供给水每谷硬度（17PPM）加入23毫升（0.05品脱）低压锅炉水控制剂。
注意事项
本剂及其溶液不要与皮肤经常或长期接触。请参阅涌标签上的附加说明。
DESCRIPTION
The development of this particular boiler treatment was promoted by the need for a simplified system of boiler water control. Because MAGNUS L.P.BOILER WATER CONTROL is a liquid, the necessity of dissolving dry powders prior to addition to boilers is eliminated. Storage problems are avoided since there is no caking or hardening which might occur if powdered type treatments become wet or damp. Incorporated in MAGNUS L.P.BOILER WATER CONTROL are phosphate, alkali and sludge conditioners in one easy to use, completely water soluble product.
USES
The use of L.P.BOILER WATER CONTROL offers chemical control over scale forming minerals, physical control over adhesive properties of scale forming salts and corrosion control of boiler metal by maintaining the necessary pH.
As evaporation of boiler water takes place, minute crystals are precipitated from boiler water. If allowed to grow uncontrolled, these crystals tend to adhere to metal surfaces to build on each other to form scale. The use of MAGNUS L.P. BOILER WATER CONTROL prevents their growth and adhesion to boiler surfaces. Conditioned, precipitated scale forming minerals are then easily removed by blow down.

PRECAUTION
Repeated or prolonged contact with the product or its solutions should be avoided. See additional precautions on drum label.
STORAGE
Store in a cool place in original container and protect from direct sunlight.

DOSAGE
LPBW CONTROL is initially dosed on the basis of hardness. The dosage needed to maintain zero hardness is approximately one litre of treatment, per one ton of feedwater,
per grain(17ppm) of hardness.
Example: To treat a boiler using 5 tons of feedwater daily having a 3 grain (51ppm) hardness:
5tons X 3 X 25ml = 375ml LPBW CONTROL daily.
The following chart shows calculated doses based on hardness and phosphate tests:
Note: In certain cases, when recommended limit cannot be maintained by LPBW alone, Hardness Control may be used as a supplement to raise phosphate level or Alkalinity Control to raise alkalinity to recommended limits.
QUICK TESTS
For Auxillary Boilers when using Low Pressure Boiler Water Control. Normally MAGNUS recommends that all appropriate tests to be done using LPBW CONTROL. However, these test may be simplified when necessary:
Hardness:
1. If the sample to be tested is highly turbid, it should first be iltered. Any suspended hardness will give erroneous results.
2. Wash shaker bottle thoroughly and rinse with sample to be tested.
3. Fill 50ml of cooled sampl e into the shaker bottle, using the graduated mark on the bottle for a guide.
4. Fill a dropper bottle with Standard Soap Solution. Using the graduated dropper (0.5ml) add apprx. 0.3ml of solution to the water in the shaker bottle. Shake vigorously. Lay the bottle on its side and check to see if the lathers permanent (last 5 minutes).
5. If the lather is not permanent or does not form at all, add more soap solution approx. 0.2ml at a time until a permanent lather is formed. Subtract 0.3ml from the total amount of soap solution added and multiply the result by 20. The result is the amount of hardness present in ppm.
