處理飲用水的話，含量低的聚合氯化鋁會(huì)有較多雜質(zhì)和水不溶物，所以要求用高含量。特別是造紙，化妝品制作中更是要用高含量的。
處理飲用水必須用飲水級(jí)的，工業(yè)級(jí)的在檢測(cè)時(shí)不檢測(cè)重金屬，另外水不溶物也高于飲用水的，總的來說飲用水級(jí)的關(guān)乎人命，不能亂用，一定要是真正的飲用水級(jí)的，如果工業(yè)級(jí)的被用于飲用水，隱患很多。而且純度
不同，工業(yè)用都是26-28%，飲用水用30%。
而污水處理的話，含量高低要求并不嚴(yán)格，含量低的不是太多就行，可以多投放些藥劑也可以達(dá)到預(yù)定的效果。

and the characteristics of the water body. At this stage, because of its many advantages, it is very popular with everyone. At this stage, we have developed a composite inorganic polymer flocculant. The Flocculation Characteristics and precipitation of this kind of flocculant will be further developed at the level of polyaluminium chloride. I believe that it will also occupy a large sales market in the future.練，銷售市場(chǎng)銷售量的絮凝劑。PAC應(yīng)用時(shí)具備絮體發(fā)生快、沉淀 性能好，水中堿度消耗少，特別是對(duì)水溫、pH值、濁度和有機(jī)物含量改變適應(yīng)能力強(qiáng)等優(yōu)勢(shì)。 聚氯化鋁的絮凝全過程事實(shí)上也是一個(gè)脫穩(wěn)流程，所謂脫穩(wěn)便是使膠體顆粒失去穩(wěn)定性的過程，液體中原先均勻分散的固體顆粒結(jié)合成很大的顆粒，進(jìn)而沉淀出來，超越凈水目的，影響其成效的要素也 特別多，如溶液PH值、溫度、拌和速度、拌和時(shí)間、水體的特點(diǎn)等等，現(xiàn)階段因其諸多長(zhǎng)處，十分受大伙兒親睞，現(xiàn)階段，咱們也研制出了復(fù)合型無機(jī)高分子絮凝劑，這類絮凝劑的絮凝特性和沉淀作用 將在聚氯化鋁的層級(jí)上再進(jìn)一步，相信未來也會(huì)占有挺大銷售市場(chǎng)！這是PAM起吸附架橋作用，使懸浮的粒子產(chǎn)生絮凝沉淀，達(dá)到凈化污水的目的。也可用于自來水的凈化，尤其是和無機(jī)絮凝劑配合使用，在水處理
4、油田化學(xué)品 如粘土防膨劑、油田酸化用稠化劑品等。(PAM) is a linear water-soluble polymer, which is one of the most widely used varieties of water-soluble polymer compounds. PAM and its derivatives can be used as efficient flocculants, thickeners, paper enhancers and liquid drag reducing agents. They are widely used in water treatment, paper making, petroleum, coal, mining, metallurgy, geology, light textile, construction and other industrial sectors.
Nonionic polyacrylamide
Uses: 1. When the suspended sewage is acidic, it is more appropriate to use non-ionic polyacrylamide as flocculant. This is because PAM acts as an adsorption bridge to make suspended particles flocculate and precipitate, so as to purify the sewage. It can also be used to purify tap water, especially in combination with inorganic flocculants, and has the best effect in water treatment.
2. Adding some chemicals to textile industry auxiliaries can be used to compose chemical data for textile sizing.
3. Dissolve non-ionic polyacrylamide into 0.3% concentration and add crosslinking agent in sand control and sand fixation. Spraying on desert can play a role in sand control and sand fixation.
4. Soil moisturizers are used as basic materials of soil moisturizers and various modified polyacrylamides.
Cationic polyacrylamide:
Usage: 1. Sludge dewatering can choose the corresponding brand of this product according to the nature of sludge, which can effectively dewatering gravity sludge before the sludge enters the filter press. When dewatering, it produces large flocs, non-sticking filter cloth, non-dispersing, less dosage, high dewatering efficiency and less than 80% moisture content of mud cake.
2. The treatment of sewage and organic wastewater shows positive electricity in acidic or alkaline medium, so flocculation and precipitation of sewage with negative charge of suspended particles in sewage is very effective, such as wastewater from alcohol factory, brewery, monosodium glutamate factory, sugar factory, meat food factory, beverage factory and textile printing and dyeing factory. Cationic polyacrylamide is several or tens of times more effective than anionic polyacrylamide, nonionic polyacrylamide or inorganic salts, because such wastewater generally has negative charges.
3. Water treatment flocculant in Waterworks has the characteristics of low dosage, good effect and low cost. Especially, the combination of inorganic flocculant and inorganic flocculant has better effect.
4. Oilfield chemicals such as clay anti-swelling agents and thickeners for oilfield acidification.
5. Paper reinforcer cationic PAM is a water-soluble cationic polymer containing carbamoyl group. It has the functions of reinforcement, retention and filter aid. It can effectively improve the strength of paper. At the same time, the product is also a highly effective dispersant.
Anionic polyacrylamide
Uses: 1. Industrial wastewater treatment has the best effect on sewage treatment, such as coarse suspended particles, high concentration, positive charges of particles, neutral or alkaline PH value of water, iron and steel plant wastewater, electroplating plant wastewater, metallurgical wastewater, coal washing wastewater, etc.
2. Drinking water treatment in many Waterworks of our country comes from rivers. The content of sediment and minerals is high and turbid. Although it can't meet the requirements after sedimentation and filtration, it needs to add flocculant. The dosage of flocculant is 1/50 of inorganic flocculant, but the effect is several times that of inorganic flocculant. Inorganic flocculant and cationic flocculation of our company can be used for river water seriously polluted by organic matter. The effect of acrylamide is better.
3. Recycling of lost starch grains in starch factories and alcohol factories now contains a lot of starch in the wastewater of many starch factories. Anionic polyacrylamide is added to flocculate and precipitate starch particles, and then the precipitate is filtered into cake shape by pressure filter, which can be used as feed. Alcohol in alcohol factories can also be dehydrated by anionic polyacrylamide and reclaimed by pressure filter.
噴霧干燥型聚合氯化鋁的產(chǎn)品質(zhì)量很多時(shí)候關(guān)系到人們的生命健康，因此，生產(chǎn)噴霧干燥型聚合氯化鋁具有明確而嚴(yán)格標(biāo)準(zhǔn)，可以保證人們的健康和安全。
滾筒式聚氯化鋁 鋁含量一般,水不溶物高,多用于污水處理.
板框式聚氯化鋁 鋁含量高， 水不溶物低. 用于污水處理和飲用處理.
噴霧干燥聚氯化鋁 鋁含量高， 水不溶物低，溶解速度快，用于飲用水及更高標(biāo)準(zhǔn)水處理.
PAC聚氯化鋁由于噴霧干燥穩(wěn)定性好，適應(yīng)水域?qū)?，水解速度快，吸附能力?qiáng)，形成礬花大，質(zhì)密沉淀快，出水濁度低，脫水性能好等優(yōu)點(diǎn)，在同樣水質(zhì)的情況下，噴霧干燥聚氯化鋁投加量減少，尤其在水質(zhì)不好的情況下，噴霧干燥產(chǎn)品投量與滾筒干燥聚氯化鋁相比，可減少一半，不僅減輕了工人的勞動(dòng)強(qiáng)度，而更重要的是減少用戶的制水成本。除此之外，用噴霧干燥產(chǎn)品可保證安全性，減少水事故，對(duì)居民飲用水非常安全可靠。When treating drinking water, polyaluminium chloride with low content will have more impurities and water insolubles, so high content is required. Especially in papermaking, cosmetics production is to use high content.
Drinking water must be treated at drinking water level. Heavy metals are not detected at industrial level, and insoluble substances in water are also higher than drinking water. Generally speaking, drinking water level is related to human life and can not be used arbitrarily. It must be a real drinking water level. If industrial level is used for drinking water, there are many hidden dangers. And the purity is different, industrial use is 26-28%, drinking water is 30%.
And sewage treatment, the content requirements are not strict, low content is not too much, you can put more medicines can also achieve the desired effect.
Henan an Jia Jing Environmental Protection Technology Co., Ltd. specializes in the production of polyaluminium chloride, which is mainly divided into drinking water level and industrial grade. The production process is mainly divided into spray method and roller method.
Drum-type polyaluminium chloride is generally used for sewage treatment because of its high water insoluble content.
Plate-frame polyaluminium chloride has high content and low water insoluble. It is used for sewage treatment and drinking treatment.
Spray drying has high content of polyaluminum chloride, low insoluble substance and fast dissolution rate. It is used for drinking water and higher standard water treatment.
PAC polyaluminium chloride has the advantages of good stability in spray drying, wide adaptation to water area, fast hydrolysis speed and strong adsorption capacity. It has the advantages of large alum, high quality and fast sedimentation, low turbidity and good dewatering performance. Under the same water quality, the dosage of spray drying polyaluminum chloride is reduced, especially when the water quality is not good, the product volume of spray drying is compared with that of drum drying polyaluminum chloride. It can be reduced by half, which not only reduces the labor intensity of workers, but also, more importantly, reduces the cost of water production for users. In addition, spray drying products can ensure safety and reduce water accidents, which is very safe and reliable for drinking water.
