SGR-1920鍋爐用緩蝕阻垢劑（磷系）
1. 產(chǎn)品介紹
本鍋爐緩蝕阻垢劑是由有機磷酸鹽和聚羧酸和堿性增效劑等復(fù)配而成，具有很高的緩蝕和阻垢性能，其耐溫性能特別好，藥劑成堿性，其PH值和爐水PH相當。
可有效的應(yīng)用于低壓鍋爐的爐內(nèi)水處理，鍋爐包括水暖、蒸汽、機車用鍋爐等，也可用于海水淡化、蒸餾劑水箱等系統(tǒng)的緩蝕防銹。
2. 性能指標
產(chǎn)品外觀 | 琥珀色液體 |
PH（1%水溶液） | 10-12 |
密度（20℃） | ≥1.10g/cm3 |
固含（%） | ≥ 20 |
3. 使用方法
按每噸水加200ppm的藥劑比例加入鍋爐補充水中即可，使用時注意排污，要求每小時排污一次，每次5-10秒，如鍋爐帶垢運行時可加大藥劑用量，勤排污，運行10-20天后反應(yīng)停爐，人工把脫落下的水垢清理干凈，防止污垢堵塞管道，然后轉(zhuǎn)入正常運行；
有條件的可測爐水濃縮倍數(shù)，控制在10倍左右，其它參數(shù)按勞動有關(guān)規(guī)定調(diào)整（如爐水PH10-12等）。
鍋爐補充水的總硬度應(yīng)控制在200mg/L以內(nèi)，若硬度過高可用石灰法或其它方法降硬度，否則藥劑的阻垢效果將受影響。
4. 包裝與貯運
(1)本品采用藍色塑料桶包裝，25Kg/桶，1t/桶或根據(jù)客戶需要確定。
(2)本產(chǎn)品儲存在陰暗、通風的庫房，并遠離火種和高溫，庫溫不宜超過30℃。
(3)與易燃、可燃物、酸類、堿類等物質(zhì)分開存放，切忌混儲。
5. 安全與防護
原液對皮膚有刺激性，應(yīng)避免與眼睛直接接觸，應(yīng)立即用大量清水沖洗，不可凝視，不可與皮膚長期接觸。須佩戴好防護眼鏡、防酸堿手套、安全帽，必要時要穿戴好防酸堿防護服。
產(chǎn)品特性
鍋爐緩蝕阻垢劑機理
01 、藥劑螯合與晶格畸變作用：無機鹽晶體生長過程是按晶格形狀有序排列，阻垢分散劑能優(yōu)先與晶體扭折位置的陽離子螫合，使晶體不能按正常規(guī)律生長，而是使晶體形成了歪晶，晶體仍繼續(xù)長大，螯合物被鑲嵌在繼續(xù)生長的晶體中，這種晶體在彈性應(yīng)力作用下容易碎裂，形成外形不規(guī)則的小晶體，晶體發(fā)生畸變，而不長大。
02、藥劑分散作用：阻垢分散劑通過物理或化學作用被吸附到無機鹽微晶及其他懸浮物粒子表面。吸附了阻垢分散劑的小晶體和懸浮物表面形成雙電層，改變了顆粒表面原來的電荷狀況，在靜電作用下，顆粒相互排斥、這樣避免了顆粒碰撞后長大沉積，并將無機鹽微晶及懸浮微粒分散在水中。
03、緩蝕作用：鍋爐緩蝕阻垢劑中的堿性增效劑成分，能有效去除水汽系統(tǒng)的溶解氧，防止設(shè)備的氧腐蝕； 同時能夠調(diào)節(jié)系統(tǒng)回水PH,避免酸性析氫腐蝕，同時能在設(shè)備表面形成有效的鈍化膜，加強設(shè)備的耐腐蝕性能。
實驗結(jié)果展示
一、緩釋效果
加藥前試片腐蝕嚴重，大量銹斑，加藥后試片一層鈍化膜，試片光滑；
二、阻垢效果
未加藥時，結(jié)垢嚴重，加藥后生成松散的水渣，易被沖走，不易粘附在設(shè)備表面上。

boiler (phosphorus system)SGR-1920
product presentation
The boiler corrosion inhibitor is composed of organic phosphate and polycarboxylic acid and alkaline synergist, with high corrosion inhibition and scale resistance performance, its temperature resistance is particularly good, the agent is alkaline, its PH value is comparable to the furnace water PH.
Can be effectively used in the boiler water treatment of low pressure boiler, boiler including water heating, steam, locomotive boiler, etc., can also be used in seawater desalination, distillation agent water tank and other systems of corrosion prevention and rust prevention.
performance index
product appearance | Amber liquid |
PH (1% aqueous solution) | 10-12 |
Density (20℃) | ≥1.10g/cm3 |
Solid containing (%) | ≥ 20 |
usage method
According to the proportion of water and 200ppm per ton of agents to join the boiler supplement water, pay attention to use sewage, discharge once every hour, 5-10 seconds, such as boiler with scale operation can increase the dosage of medicine, frequently sewage, running 10-20 days, artificial fall off the scale cleaning, prevent dirt blocked pipe, and then transferred to normal operation;
The concentration ratio of measurable furnace water can be controlled at about 10 times, and other parameters should be adjusted according to the relevant labor regulations (such as furnace water PH 10-12, etc.).
The total hardness of the boiler supplementary water should be controlled within 200 mg/L. If the hardness is too high, the lime method or other methods can be used to reduce the hardness, otherwise the scale resistance effect of the agent will be affected.
