Description

Packing method for asphalt

The present invention relates to a kind of packing method of goods, have more the say so packing method of pitch of this locality.

Pitch for example No. 10 building asphalts is a kind of broad-spectrum architectural waterproof materials, pitch is produced in China and has been used existing decades, the packaging Problems of pitch is never solved well, pitch all is in bulk for these years, just do not pack, give the storage of asphaltic products like this, transportation, use brings very big inconvenience, since pitch be not packaged in the hardening in winter frangible have be Powdered, summer, softening adhesion became one to stick together greatly, make loading and unloading, transportation, keeping, storage and sale bring very big inconvenience, especially there is part pitch to be thick liquid in summer, polluted transport vehicle, easy-clear not again after the pollution, because pitch does not have the open ground of packing to stack, easily sneak into for example sandy soil of impurity, limestone etc., thus the quality and the in-use performance thereof of pitch influenced, because exposed bulk storage has been wasted stacking field boundary ground; Owing to contain objectionable impurities in the pitch, for example contain carcinogen, easily cause pollution to soil, water source, environment, in addition, because pitch does not have the bulk storage of packing, rainwater stays that one of weather one thermosetting sticks together in the slit when rainy, rainwater is wrapped in wherein, cause bumping in when fusing, the pot phenomenon of overflowing, sometimes also causing fatal accident, is the hidden danger of an accident, and bulk asphalt also has the big problem of another one to have no idea exactly with trade mark and producer, cause opportunity for the personation low-quality goods, damaged customer's interests.

Because the nothing of pitch packing has caused a lot of problems, human craft paper packing is arranged, owing to pack the adhesion that has solved between the pitch with paper, problems such as storage, sale because the pitch of paper web packing all is the geometric configuration of comparison rule, are convenient to pile up neat again, when transportation, also reduced useless space, increase load-carrying quantity, reduced the transportation number of times, reduced traffic cost.But, owing to also brought new problem with wrapper, the pitch of the wrapper for example general weight of pitch of paper web packing is the 50-100 kilogram, must smash in winter during use, need during summer to cut, time-consuming, strengthened labor intensity of operating personnel, and because weather temperature height, pitch clings wrapper and is difficult for tearing, and has to pitch is melted with wrapper, so must pull wrapper come out from the pitch of fusing, like this, wrapper brings out a lot of pitch, and one has wasted pitch, has caused the pollution to environment again, and often cause operation element personnel's scald accident, very dangerous.

Purpose of the present invention just is to work out a kind of new packing method of pitch, after pitch is packed with this new packing method, the all advantages that not only have wrapper pitch, and can overcome the weak point of wrapper pitch again, utilize this packing method can prevent adhesion between the pitch in other words, be convenient to again store, sell and transportation, when using pitch, needn't smash again Dong Xiaqiuchungeji, cutting, alleviate labor intensity of operating personnel, not being afraid of pitch again clings its external packing, needn't from the pitch of fusing, pull the external packing of pitch again out, thereby avoided the generation of the scald accident of operating personal, reduced the waste of pitch, free from environmental pollution again.

The present inventor has studied the various packing that can be used for packaged asphalt to achieve the above object, research is with after certain suitable packing packaged asphalt, pitch and its external packing can be melted together, housing material is melted in the pitch, again can not be owing to exterior material is melted in the degradation that wherein makes pitch.

The packing method of a kind of pitch of the present invention is in the plastic film bag of exactly pitch being packed into.

For the ease of the transportation of piling up of pitch, again so that pitch is certain geometric configuration, in the plastic film bag that the geometric configuration with asphalt blocks of again asphalt blocks of certain geometrical shape being packed into adapts for well.

The geometric configuration of said asphalt blocks is good with square, cuboid, cylinder.

Said plastic film bag be shaped as square, oblong, cylindrical shape for well.

Make the material of above-mentioned plastic film bag, should have higher intensity, can sustain the extruding under certain external force effect, torsional buckling and to the relative stability of temperature, under the lower situation of temperature, be difficult for embrittlement, guarantee the integraty of packing, and any chemical reaction can not take place with pitch in this material, and influence the quality and the performance of pitch, under the temperature of asphalt melting, can melt soon again, can mix mutually uniformly with pitch again after the fusing, form uniform phase body, containing the quality of pitch of plastic film material and performance again can not be therefore and variation, found out commercially available polyvinyl chloride plastic film (PVC) through contriver's test of many times, sealed polyethylene plastic (PE), high density low pressure polyethylene plastic sheeting (HDPE), lower density low pressure polyethylene plastic sheeting (LDPE), polyacrylic film (PP), polystyrene plastics film (PS), the wherein any plastic sheeting of general polystyrene plastic sheeting (GPPE) all meets above-mentioned requirement as asphalt packing material, so plastic film bag is the polyvinyl chloride plastic film bag, the sealed polyethylene plastic bag, high density low pressure polyethylene plastic film bag, lower density low pressure polyethylene plastic film bag, the polyacrylic film bag, the general polystyrene plastic film bag, polystyrene plastics bag film a kind of bag wherein.

The comparison of No. 10 asphalt performances of No. 10 pitches of table 1 and the 6098 high density low pressure polyethylene plastic film materials (containing milky white master batch 6%) that contain fusing.

No. 10 pitches of softening point standard contain the membraneous material of fusing
