Abstract
The utility model relates to a drainage antirot tube which is a drainage tube which is used for an underground mining in a mine. The inner wall of the existing steel tube body is provided with an epoxy resin protective layer and glass cloth in a cloth watering mode so that the corrosion problem of the drainage tube is radically treated, and the service life is extended. The utility model is especially suitable for drainage for a water mine whose acidity pH is less than 5.
Description
The utility model relates to the waste pipe that the down-hole, mine is used.
Drainage underground is one of top priority of mining, what at present the waste pipe of down-hole mainly used is cast iron or cast-steel pipe, more is to use seamless steel pipe, and the above two one are to be not easy to install and maintain and replace, most importantly damage easily in the down-hole, its price is expensive relatively.For the latter, because most of mines are acid water, working life is very short, is the mine water of 4-4.5 for acid pH value, and seamless steel pipe can only use as many as 1 year half a year, and acid pH value only used two weeks to two more than ten day at the steel pipe below 4 o'clock, consumed greatly.
The purpose of this utility model is the waste pipe that a kind of acid-resistant anti-corrosion will be provided.
Concrete scheme of the present utility model is: the inwall at steel pipe waters cloth one deck epoxy resin protective layer and one deck glass fibre cloth at least.Epoxy resin preferably uses E-42(634) type epoxy resin.
Characteristics such as it is good to the utlity model has the acid-resistant anti-corrosion performance, is easy to manufacture, and cost is low, and the life-span is long.
Below in conjunction with accompanying drawing the utility model is further described:
Accompanying drawing is a sectional view of the present utility model.
Embodiment 1: at the inwall of steel pipe 1 flow coat one deck E-42(634 at first) epoxy resin protective layer 3, for improving its performance, ginseng has an amount of ethylenediamine curing agent and o-benzoic acid dibutylester plasticizing agent and quartz flour bulking agent therein; Be stained with one deck glass fibre cloth 2 then, be coated with one deck epoxy resin protective layer at last again, treat to do in 24 hours solid getting final product.
Embodiment 2: at the at first washcoated one deck Epon828 of inwall of steel pipe 1 epoxy resin protective layer 3, ginseng has an amount of polyamide resin 650 curing agent and polyester resin plasticizing agent and quartz flour bulking agent therein; Be stained with layer glass silk cloth 2 then, treat to do naturally in 24 hours solid getting final product.
Claims (2)
1, a kind of draining anti-corrosion pipe that is used for the down-hole, mine has steel pipe, it is characterized in that: water at least on the steel pipe inwall and be furnished with one deck epoxy resin protective layer and one deck glass fibre cloth.
2, anti-corrosion pipe according to claim 1 is characterized in that: the epoxy resin of the cloth that waters is E-42(634) epoxy resin.
