Description

HEAT-RESISTING AND ANTI-STICKY BAG FOR ASPHALT

Technical Field of the Invention

The invention relates to a heat-resisting bag for asphalt, more specifically this invention relates to a bag-formed multi-layered packaging for asphalt and the process for making the same, wherein the inner surface has a special layer of heat-resistance and anti- sticky against the asphalt, therefore at the time the asphalt being used, there is no remaining asphalt left at said inner surface of such a bag-formed multi- layered packaging.

Background Art

Various types of form and design of packaging or bag could be obtained easily, each of bags could be designed based on both form and strength according to the usage as needed. Also, raw materials being used for making the bag would be depending on the usage.

In order to limit the problem to be discussed relating to the packaging or bag of the invention, then in the discussion, such a packaging or bag will be specified, particularly to a packaging or bag according to the usage of a packaging or bag for asphalt.

The asphalt is like paste and has sticky characteristic, having a melting point between 45 -52°C. At a temperature around 45°C, this asphalt would be soft and starting to melt. In order to take the asphalt out of drum and tank, or vessel, it should be heated to make it flow out of drum, tank or ship.

Several usage of asphalt to include for example road development projects, plantation development projects, factory development projects, highway development projects, airport development projects, etc. In addition, asphalt could be used for example to make a roof protecting layer and to repair by patching the body of wooden boat to prevent leakage, etc.

Below is a summary of asphalt during the process and storage by use of steel drum:

- Temperature of the process of asphalt at 300°C. - Temperature when filling process to steel drum is about 160- 180°C.

- Time to cool down till harden about 2 days.

- Softening point at 45 - 56°C.

- Transport for bulk is with heat (vessel and tank).

- The storage of Asphalt is out door.

- The usage of Asphalt is at construction site and out door with temperature about 45- 50°C.

Problem and disadvantage of the existing in drum packaging and bulked:

Heavy packaging; The smallest packaging in steel drum is 150 kgs, it is heavy and can not be carried by one man. Since it is heavy; it is not convenient for shop to retail on in shop inside the city or like cement and other construction material.

Distribution Problem; Drum and bulk are not accessible to the small areas require addition equipment to load and unload asphalt.

Waste of Energy; The process at site for road construction; it required energy more than 40% compare to process with the easy-peel bag.

Waste Inside Steel Drum 5-10%. Once the steel drum is heated and most of the asphalt is take out, there is 5 - 10 % of asphalt is stick to the drum.

Less Popular. The asphalt become less popular due to the packaging, so the Fisherman and small housing contractor, small road repaired; has a hard time to find or buy it so they find other alternative material to do the job; which is much more expensive than Asphalt.

Limited and Expensive Steel Drum. Steel drum is scarce in the market and expensive, so it is the disadvantage to the Asphalt Manufacture to sell and to distribute their product. The cost of packing is high and it is not suitable for other purpose that required small quantity of asphalt at the time.

Most of the Asphalt is stored and distributed through hot bulk mode which used a lot of energy; and it must be heated all the time during storing to maintain its molten states and discharge.

Pollution; Since the bulk asphalt required heat during storage and distribution; it creates carbon and damage the environment.

Bulk quantity is sold through the tank, therefore small user are not able to purchase in bulk as it will be too much, and delivery investment of truck is high; and special design, and can not be used for other purpose. Furthermore, in the aspect of various types of alternative packaging made of plastic, that is started to be used and becoming interested in the market nowadays, there are some problems and disadvantages. Among said problems or disadvantages include: packaging in the form of conventional bag or sack is not heat-resistant, therefore asphalt should be kept in a lower temperature for the asphalt being filled in said conventional bag or sacks; this lower temperature cause the asphalt become much thicker, so very high pressure will be needed to force the asphalt filling into bag or sack packaging; and when the asphalt would be taken out of the bag or sack, then some sticky asphalt will still adhere to inner surface of such a bag or sack packaging; this results in a financial loss for the reason of inefficient process. Another disadvantage of conventional asphalt packaging is related to ambient temperature; asphalt tends to be melted when ambient temperature is increased, then this melted asphalt will flow through small gap of sewn yarn around conventional bag or sack-formed packaging. This also will result in damage the consumers because of losing the content or volume asphalt of said packaging.

In order to overcome disadvantages and problems related to various conventional containers or packaging, such as conventional steel drums or bags and/ or sacks in form as mentioned above, inventor provides a novel packaging of bag or sack in form; this packaging is extremely heat resistant, anti-sticky and anti-leakage suitable for asphalt, so in other words, this packaging of bag or sack in form is a very practical, efficient, economical and easy to use.

This novel packaging according to the invention has a heat resisting characteristic, and easy in use especially for asphalt to be filled.

Therefore, this novel packaging of bags or sacks in form according to the invention is becoming a solution against various problems and disadvantages of conventional containers or packaging.

Process 1.

Take the woven cloth min of 10 x 10 800 D with the strength of 60 kgs per 5 cm; and the low elongation approximately 18-22 %. The process at the weaving machine, that the surface of the woven must be flat and no folding, if the tape is folded during weaving, it will make the surface uneven and will affect the second and third coating process. Then process coating on one side of the woven sheet, min 25 mc thickness; the coating is to cover the uneven surface of the woven for further coating of the HRRA ( heat and release agent). The max elongation on the woven sheet of 18% and max of 22% is to prevent the shrinkage of the woven during the coating of the silicon which will go through heat oven about 120-150° Celsius. If the elongation is too big percentage the woven will shrink and the surface of the lamination will be damage and will create holes or uneven coating of both PP coating material and the silicon on the surface of the woven; hence the leak of the asphalt will happen.

Then take this coated wove for process further with sandwiched lamination to the paper. The lamination of the sandwich is about 27-30 mc. The purpose of the sandwich lamination with the paper is to stabilize the shrinkage of the woven during process coating of the HRRA chemical of which coating, the woven will go to the oven the temperature about 120- 150° C. If the adhering of the woven to paper is good the shrinkage is a minimum; and the HRRA chemical will be at the best result for anti heat and anti sticky of the asphalt.

Then the woven cloth will be processed HRRA coating; and one side of the woven will be left not coating about 4-5 cm, this is for the further process of sealing into tube.

Process 2

Take the woven from process 1; to make a tube by process through the tubing machine for gluing, sizing in width and length, or by sewing at the side and cover with shift-proof (material for anti leak). Then the woven tube will be closed at the bottom by sewing and Cover with sift proof for anti leak. This will be the inner layer of asphalt bag that has direct contact with the asphalt. The parameter of the top of the bag about 5-6 cm will be sewn with the sift proof which has width about 6 cm; the function of the sift proof is to prevent the leak from the sewing line. For best result; sift proof is essential, but for short term storage and delivery, sift proof is not required.

Process 3

Prepare the HDPE liner for the second layer, the thickness of the film is 15 -20 mc; the function of the HDPE liner is for the protection of the leaking of the asphalt from the inner layer through the sewing hold from the top and bottom and the seam in the middle.

Size of the Liner is to be bigger than the inner bag by about 5 cm and longer about 20 cm. This is for the reason of easy insert into the bag and some space for the inner bag to expand; the length is for folding to cover the sewing area of the bag on the top. The HDPE liner has be at this thickness 15-20 mc as the static of thin film is high, so when the bag is wet; it will stick better to the paper bag inside.

Process 4 Take the woven sheet sized as required size of bag then coated with the PP coating; with the UV stabilizer, and color desired; in this case is black color for representation of product; and black color also protect the Sun light from damage the plastic woven. So the bag can be stored outdoor much longer.

Then take the black woven coated with to process in the tubing machine for sizing, in width and length and printing; this will be outer bag and the length desired, in this case is 78 cm. Then close the tube at the bottom by sewing, the folding will be double fold to prevent the leak of the asphalt.

The function of this bag is to protect the inner layer during storage, and transport of the bag. The function of the UV coated is to prevent the bag is direct contact with sun light.

Process 5.

Insert the inner bag (material process in process 1 & 2), then the

HDPE liner as second layer, then cover the two layers with the outer bag (process 4).

Bag design and Process Spec B

3 Layer Easy Peel Woven Type with Heat Resistance asphalt bag.

[From Inner : HRRA PP Woven coated/HDPE/PPwoven coated color), Asphalt bag for Spec 60/70 and 80/ 100 with the softening point from 45 - 52°Celsius.

Process.1

Take the woven cloth min of 10 x 10 800 D with the strength of 60 kgs per 5 cm; and the low elongation approximately 18-22 %. The process at the weaving machine, that the surface of the woven must be flat and no folding, if the tape is folded during weaving, it will make the surface uneven and will effect the second and third coating process. Then process coating on one side of the woven sheet, min 25 mc thickness; the coating is to cover the uneven surface of the woven for further coating of the HRRA (heat and release agent). The max elongation on the woven sheet of 18% and max of 22% is to prevent the shrinkage of the woven during the coating of the silicon which will go through heat oven about 120-150 Celsius. If the elongation is too big percentage the woven will shrink and the surface of the lamination will be damage and will create holes or uneven coating of both PP coating material and the silicon on the surface of the woven; hence the leak of the asphalt will happen.

Process 2

Take the woven from process 1; to make a tube by process through the tubing machine for gluing, sizing in width and length, or by sewing at the side and cover with the felt (material for anti leak). Then the woven tube will be closed at the bottom by sewing and Cover with sift proof for anti leak. This will be the inner layer of asphalt bag that has direct contact with the asphalt. The parameter of the top of the bag about 5-6 com will be sewn with the sift proof which has width about 6 cm; the function of the sift proof is to prevent the leak from the sewing line. For best result; sift proof is essential, but for short term storage and delivery, sift proof is not required.

Process 3

Prepare the HDPE liner for the second layer, the thickness of the film is 15-20 mc; the function of the HDPE liner is for the protection of the leaking of the asphalt from the inner layer through the sewing hold from the top and bottom and the seam in the middle.

Size of the Liner is to be bigger than the inner bag by about 5 cm and longer about 20 cm. This is for the reason of easy insert into the bag and some space for the inner bag to expand; the length is for folding to cover the sewing area of the bag on the top. The HDPE liner has be at this thickness, the thinner film when the bag is wet, it will stick better with the inner bag.

Process 4

Take the woven sheet then coated with the PP coating; with the UV stabilizer, and color desired; in this case is black color for representation of product; and black color also protect the Sun light from damage the plastic woven.

Process 5,

Insert the inner bag (material process in process 1 85 2), then the HDPE liner as second layer, then cover the two layers with the outer bag (process 4).

The process of the material of the bag at the inner layer that contacts with the asphalt is applied by HRRA chemical therefore the Asphalt is not stick to the material of the bag; therefore there is no waste with the packaging of the Easy Peel Bag.

The design of the bag from the sewing with the sift proof on top and bottom of the inner layer of the bag has prevent leak, even through the bag is sewn by the thread that is cover by the sift proof; small leak will happen if the bag is store at the temperature around the bag nearly or more than the softening point; it will melt and start to leak out of the bag. The sift proof will make the asphalt stick to the itself and slow down the leak.

The paper sandwiched laminated on the inner has the propose of absorbing the water and keep the surface of the asphalt harden faster, and the cool water absorbed to the paper will make the asphalt cool down faster, during the packing and unpacking as EasyPeel bag required water when filling, storing out door, and opening the bag. Therefore cooling time of asphalt can be shortened from 2 days to 4-6 hours.

The second ply of the bag is HDPE for small size and PE for heavy duty (200-1000 kgs) has the function of the preventing 100% leak; the thin layer approximately 15-20 mc for small weight, 75 mc for 200 kgs and up., since the film is very thin and static is high; it will stick to the inner layer (paper) so it will absolute prevent the leak through the sewing holes and the sift proof. So the film is like a good seal for the bag.

Outer layer is Polypropylene woven coated with black color for small bag; (for big bag is white or any color desired.as storage will be indoor); with UV stabilizer; it will keep the bag longer in the sun.

Since the asphalt is packed with the EasyPeel bag, there is no waste, the bag makes the asphalt more competitive; easy to distribute, and it can be retailed in any construction shop in the near future. Small users, and other application of the asphalt besides the road construction and small repair of road can be done without big budget and any time as the supplied of asphalt will be more common like other construction material.

The bag is strong, can be stacked up to 20 stacks without damage the bottom stack; therefore the cost of the delivery on the vessel can be much more competitive. The bags can be transferred as is, and no need extra protection; like jumbo bag; from warehouse to truck, truck to warehouse, to vessel, then to truck and to warehouse or site; min 8 -10 times. High stacking, save space, save money on investment on the warehouse, and trucking or renting.

The bag can hold the high temperature up to 130°C (with the same method of filling with the water tank and cooling with the water pool) so the flow during the packing is faster, therefore the out put of the filling is much more than other bag; hence; the return of the investment will be faster.

The storage of bag is required no heat; therefore, storage and distribution of bag is saving energy and create clean air. The seller or stockiest of the asphalt can enjoy the saving of the energy for the storage of the asphalt in bag.

EasyPeeL bag gives friendly working environment. Many accidents had occurred during process in the asphalt heating tank as the drums often and accidentally drop to the heating tank and the hot asphalt is splashed all over and it can get to the workers who work around the mouth of the asphalt heating tank.

As EasyPeel bag is design to be open before used; so the workers need area to work on the opening of the bag, the area is design under and quite for away from the mouth of the heating tank. Afterward it is transferred to the tank by the conveyor. Since the asphalt is with the small weight; the splashing is not likely to occurred and if there is; it is a small splash and but it can not get to the workers.

High output at the mixing plant as asphalt is cooked faster with smaller lump again saving the time and energy at site. The output is more than 40 % from compare to output from using drum packaging.

Benefit of the invention:

Reduce the cost of packaging for Asphalt more than 50% from steel drum to easy peel bag [EZ PEEL BAG].

Reduce the waste of Asphalt from 5-10% (left over inside the steel drum after heating) to nearly 0% waste; no left over inside the bag.

Create better way to distribute Asphalt in smaller packaging; hence the asphalt will serve other industries beside the road construction such as housing and wood working product and boat industry.

Save energy for heating Asphalt in bulk tank during storage and transport by pack in bag.

Save energy for heating asphalt at site as taking out the asphalt from drum take longer. The saving of the energy and time can be up to 45%.

The asphalt will be more competitive and affordable for small user; and saving cost to all road and highway construction.

Conclusion; the EasyPeel bag has created tremendous of saving in just about every area, substitute for the existing packaging with much lower cost, saving energy for storage and distribution, saving in freight and warehouse as it can be stacked very high and no need extra protection, save environment, friendly working environment and most of all everybody can afford from small to big quantity.

Sample of cost saving at conblock, road project at Kalimantan: Drum a ainst EZ PEEL bag.

Addition Equipment needed for moving by man carry no investment Create Job not much in every aspect.

With the example above, EZ PEEL compares to drum in value.
