Djin, TB

Fumigation Science: The Mechanics of "Jin, TB"

"Jin, TB" is a high-performance fumigant based on aluminum phosphide, designed specifically for the protection of stored grain and warehouse facilities. Unlike contact insecticides, this product operates in the gas phase. Upon exposure to ambient humidity, the tablets trigger the release of phosphine gas (PH3). This gas possesses exceptional penetrating power, allowing it to permeate deep into grain bulks—such as wheat, barley, corn, rice, oats, rye, and peas—effectively targeting pests that live inside the kernels.

Targeting Stored Product Pests

The formulation is specifically calibrated to neutralize a wide array of destructive insects, including the granary weevil, rice weevil, saw-toothed grain beetle, merchant grain beetle, Indian meal moth, and grain moth. By acting on all life stages of these pests—including eggs, larvae, and pupae—it ensures a comprehensive decontamination process.

Technical Specifications and Application Standards

• Chemical Profile: As a Class 1 hazardous material, "Jin, TB" requires stringent adherence to safety protocols. Fumigation must be conducted exclusively by certified professionals in strictly sealed environments.
• Quality Control: The product is manufactured under the joint standards of "Jining City Yamin Chemical Plant" (China) and "Unicity Enterprises L.P." (UK), ensuring consistent tablet mass and predictable gas release rates.
• Environmental Factors: The rate of phosphine release is temperature-dependent. At temperatures below 10°C, the reaction kinetics slow down significantly, necessitating longer exposure times to achieve complete insect mortality.

Properly executed fumigation with "Jin, TB" maintains the milling and baking quality of the grain, provided that the necessary post-treatment aeration (degassing) is performed. The technology remains the industry standard for preventing quality loss in long-term grain storage facilities.
