Description
Изобретение относитс к электротехнике и может найти применение, в частности, дл снижени сопро гивлени растеканию заэемлителей.The invention relates to electrical engineering and can be used, in particular, to reduce the resistance to spreading of users.
Известен состав, понижающий сопротивление растеканию заземлителей на основе акриламида СKnown composition that reduces the resistance to spreading of earthing based on acrylamide C
Недостатком указанного состава вл етс присутствие в электролите хлористых солей. Как известно хлориды наиболее опасные в коррозионном отношении соли. Попада в грунт, при искусственной обработке его сол ми, ионы хлора уничтожают пленку окислов на стали, увеличиваю анодные повехности и при наличии хороших катодов (железобетонных фундаментов ), усиливают коррозионные разрушени элементов заземл ющих систем. Кроме того, это довольн сложный состав.The disadvantage of this composition is the presence of chloride salts in the electrolyte. As it is known chlorides are the most dangerous in terms of corrosion salts. Getting into the ground, when artificially processing it with salts, chlorine ions destroy the oxide film on the steel, increase the anode surfaces and, in the presence of good cathodes (reinforced concrete foundations), increase the corrosion damage of the elements of the grounding systems. In addition, it is a rather complex composition.
Известен состав дл обработки вы коомного грунта на основе природног гипса, примен ющийс дл уменьшени удельного сопротивлени грунта и коррозионного воздействи на заземлтели из черной и оцинкованной стали С2..A known composition for treating cement based on natural gypsum is used to reduce the resistivity of the soil and the corrosive effect on the groundings made of black and galvanized C2 steel ..
Недостатком состава вл етс небольшой эффект снижени сопротивлени грунта и антикоррозионного свойства.. При добавлении гипса в / грунт coпpoтивлeниJe его уменьшаетс в среднем только на 60%, а защита от коррозии увеличиваетс на 14%.The disadvantage of the composition is a small effect of reducing soil resistance and anti-corrosion properties. When adding gypsum in / soil, its resistance decreases on average by only 60%, and corrosion protection increases by 14%.
Цель изобретени - создание состава , обладающего низким сопротйвлеThe purpose of the invention is to create a composition having a low resistance.
нием растеканию заземлителей в сочетании с повышенной антикоррозионной стойкостью.the spreading of earthing in combination with increased corrosion resistance.
Поставленна цель достигаетс тем что состав на основе гипса дополнительно содержит азотнокислый калий (KNOj) , окись хрома (Cf-jOj ) пирофосфорнокислый нaтpийi Noц,P20Y 10Н20 при следующем соотношении компонентов , мас.%:The goal is achieved by the fact that the composition on the basis of gypsum additionally contains potassium nitrate (KNOj), chromium oxide (Cf-jOj) natrophosphate sodium natrii Nots, P20Y 10H20 in the following ratio of components, wt.%:
Са504-2 2 10-97,0Ca504-2 2 10-97.0
KNOj1,0-30,0KNOj1.0-30.0
Cr-20j1,0-30,0Cr-20j1.0-30.0
1,0-30,0 Дл повышени окислительных свойств солей окислительного типа азотнокислого кали , окиси хрома в гипс введен пирофорсфорнокислый натрий, способствующий переводу рыхлых гидрозакисей железа в более прочные защитные пленки. Кроме того, введение в гипс вышеуказанных солей способствует удержанию влаги в грунте и поглощению последней из атмосферы , что создает более стабильный режим снижени сопротивлени грунта. ; В табл. 1 приведен рецептурный v состав данного высокоомного грунта. 1.0-30.0 To increase the oxidative properties of the salts of the oxidizing type of potassium nitrate, chromium oxide, sodium pyrophosphorate sulphate is introduced into gypsum, which promotes the transfer of loose iron hydroxakis to stronger protective films. In addition, the introduction of the above salts into gypsum contributes to the retention of moisture in the soil and the absorption of the latter from the atmosphere, which creates a more stable mode of reducing the resistance of the soil. ; In tab. 1 shows the prescription v composition of this high-resistance soil.
В табл. 2 приведены свойства предлагаемого состава по сравнению с известным.In tab. 2 shows the properties of the proposed structure in comparison with the known.
Как видно из представленных данны сопротивление грунта, содержащего даный состав снижаетс на 32% по сравнению с известным в сочетании с повышенной антикоррозионной стойкостью.As can be seen from the presented data, the resistance of the soil containing this composition is reduced by 32% compared with the known in combination with increased corrosion resistance.
