At that point spread the surface with 5 cm of untreated soil to forestall corruption of the polymer by sunlight and stagnation of water on a shallow level.
  • Be particularly cautious not to put the unmixed dry item at the base of the gap. After hydration, the item would destabilize the plant.

Usage for Bare-root Dipping

  • Mix 1 kg of SAP in 150-200 liters of water. (Sums differ contingent upon the saltiness of the water)
  • Slowly pour in the item while mixing the water to acquire a dressing without unloading of particles.
  • Let the dressing wait for 15 minutes, the time required for SAP to arrive at its greatest ingestion. It is critical to get a dressing that will hold fast totally to the roots. The more extended the development time, the thicker the dressing will be, and the better it will stick to the roots.
  • A water-solvent nematocide and additionally fungicide may likewise be added to the planning to secure plants against nematode and parasitic assaults.

Usage for Flower Transport

SAP as the hydrogel might be set in fixed plastic pockets. When solidified, the pockets are frequently utilized in the vehicle of heat-sensitive plant items, for example, cut flowers. The hydrogel has incredible protection from heat burn and doesn’t spill in the wake of defrosting.

Usage for Hydroseeding

The other favorable position of SAP is that it forestalls cellulose mulch from turning out to be hardpan during a drought. The mulch stays circulated air through and permits the seeds to grow rapidly. SAP additionally makes it conceivable to lessen the measure of mulch.

  • SAP must be added last to the hydroseeder tank, after different parts: seeds, composts, mulch, and so on.
  • Stir in any event 15 minutes before spreading.

Drilling

In oil or gas, well drilling lost circulation happens when drilling liquid, referred to regularly as “mud”, streams into at least one land arrangement as opposed to returning up the annulus. Lost dissemination can be a major issue during the boring of an oil well or gas well.

SAP Drilling Mud Additive which is another natural assurance item with great water-absorbable and swellable properties, can viably against lost dissemination.

What is lost circulation?

In oil or gas well drilling, lost circulation occurs when drilling fluid, known commonly as “mud”, flows into one or more geological formations instead of returning up the annulus. Lost circulation can be a serious problem during the drilling of an oil well or gas well.

Consequences

1. Blowout

If the amount of fluid in the wellbore drops due to lost circulation (or any other reason), hydrostatic pressure is reduced, which can allow gas or fluid which is under higher pressure than the reduced hydrostatic pressure to flow into the wellbore. An influx of gas or fluid into the wellbore, known as a” kick”, can lead to a blowout.

2. Dry Drilling

Dry drilling occurs when fluid is completely lost from the wellbore without actual drilling coming to a stop. The effects of dry drilling range from as minor as destroying a bit too as serious as major damage to the wellbore requiring a new well to be drilled. Dry drilling can also cause severe damage to the drill string, including snapping the pipe, and the drilling rig itself.

Solution of lost circulation

Traditional Solution of lost circulation

There are some options are available when lost circulation occurs, depending on the severity: Increasing the viscosity of the fluid with bentonite or with the addition of other additives, which typically includes organic plant particles.

SAP Drilling Mud Additive – A better solution for lost circulation

It is a new environmental protection material with good water-absorbable, thickening property and swellable properties, can effectively against lost circulation.

Other Applications

It finds broad utilization in various explicit items because of its stunning properties; some of them might be recorded here:

  • As an added substance for functional covering in numerous particular applications,
