Abstract
The present invention discloses an industrial blasting fuse with high humidity resistance and a producing method thereof. The present invention is characterized in that external coating materials of the blasting fuse are changed from water solution of polyvinyl alcohol into mixed materials with asphalt as a main component. The performance of water resistance, moisture protection, mildew protection and denaturation of the blasting fuse is higher than that specified in the standards of common industrial blasting fuses, production equipment is not added, and the cost is not increased. The products are particularly suitable for high-temperature moist regions and underwater operation.
Description
The present invention relates to a kind of industrial blasting fuze and manufacture method thereof.
Regulation according to GB9108-1995 " industrial blasting fuze ", the present industrial blasting fuze of China is divided into two kinds on coventional type and deflagration type, this standard is stipulated industrial blasting fuze water resisting property, becoming diameter less than the rope of 25cm volume the safety fuse platter, is 20 ℃ in temperature, and the degree of depth is after soaking 4 hours in the hydrostatic of 1m, take out sample, wipe appearance moisture, cut off appearance rope head, the some examination still meets the combustionproperty requirement.For satisfying the water resistance requirement, the quick-fried office of the former people of Ministry of ordnance Industry had once issued the product figure WD419 of industrial blasting fuze, two kinds of industrial blasting fuze appearances of regulation coventional type deflagration type moisture-proof barrier is a polyvinyl alcohol water solution, this regulation is accepted by the nearly all safety fuse producer in the whole nation, and do not change decades.
In fact, industrial blasting fuze is in warehousing, and it is very inequality in transportation and the use water repelling property being required, and the water repelling property of prescribed by standard can not satisfy all occasions that safety fuse uses.In certain areas, China south, be subjected to the influence of plum rains high temperature season, underwater demolition particularly, the water repelling property of general requirement can not satisfy under the above-mentioned environment for use industrial blasting fuze water resisting property, moistureproofness, mildew-resistant are become performance demands, thereby the plastics industry safety fuse that high waterproof occurred and coated by PVC.But in the manufacturing processed of product, the coating of plastics moisture-proof barrier must realize that by independent operation manufacturing cost greatly increases on Special Equipment.
The purpose of this invention is to provide the sex change of a kind of anti-water moistureproof and mildewproof and can be higher than the GB9108-1995 standard, and production unit, operation, industrial blasting fuze and manufacture method thereof that cost is constant substantially.
Technical scheme of the present invention is: under the situation that does not change the industrial blasting fuze production process, only changing the composition of outer coating material-changed into pitch by polyvinyl alcohol water solution is the compound of main component, and its appearance " true qualities of paper and cotton thread " is changed into chocolate.
The proportioning raw materials of outer coating material is: petroleum pitch 40 ± 1%, ceresine 15 ± 1%, paraffin 10 ± 1%, talcum powder 35 ± 1%.
Manufacture method is: 1, pitch is removed packing and surperficial sand, by the ratio of components weighing, put into a pot internal heating, all behind the no bubble of fusing, pull impurity out.2, add ceresine and paraffin, heat fused successively by ratio of components.3, after pitch, ceresine, paraffin are fully miscible, add talcum powder one by one slightly and ceaselessly stir, it is mixed.4, through abundant interfused coating, under the situation of no bubble and pimple, pour mold cools down into, the warehouse-in that is cut into small pieces after solidifying is stored.When 5, using the pitch that processes got the raw materials ready and send into the safety fuse production line, add " safety fuse spinning " operation.
Advantage of the present invention is: 1, the sex change of the anti-water moistureproof and mildewproof of product can be higher than the GB9108-1995 standard, has enlarged the product use range.2, do not change former industrial blasting fuze production process and equipment.3, raw material is easily purchased, and cost is low, thereby does not increase the products production cost.
The present invention develops according to the China market demand, for many years, has stood strict test at China's southern area of relative humidity and extreme temperatures, receives praises from customers.The present invention and general industry safety fuse performance are compared as follows table:
Claims (2)
1, a kind of high moisture-proofing industrial blasting fuse is characterized in that: its outer coating material is to be the compound of major ingredient with pitch.
2, a kind of manufacture method of high moisture-proofing industrial blasting fuse is characterized in that: the proportioning raw materials of outer coating material is: petroleum pitch 40 ± 1%, and ceresine 15 ± 1%, paraffin 10 ± 1%, talcum powder 35 ± 1%; Manufacture method is: (1), pitch is removed packing and surperficial sand, by the ratio of components weighing, put into a pot internal heating, after off-bottom does not have bubble, pull impurity out; (2), add ceresine and paraffin successively, heating is dissolved by ratio of components; (3), after pitch paraffin ceresine is fully miscible, add talcum powder one by one slightly and ceaselessly stir, it is mixed; (4), through abundant miscible coating, under the situation of no bubble and pimple, pour mold cools down into, the warehouse-in storage is cut into small pieces after solidifying; (5), when using the pitch that processes got the raw materials ready and sends into the safety fuse production line, add " safety fuse spinning " operation.
