Latex gloves

(natural rubber coated gloves)

Taken from rubber tree sap, stabilizer ammonia water (about 40%, ammonia accounts for 0.6%), first soaked in methanol (curing effect), soaked in glue, wrinkling area (acetic acid, kerosene, xylene, etc. are mainly used for wrinkling area);

Nitrile gloves

(synthetic rubber coated gloves)

Synthetic from acrylic acid and butadiene, first soaked in methanol solution, methanol has a curing effect to prevent the adhesive layer from penetrating into the inside of the gloves;

Waste gas emission source of protective gloves

Salt immersion area (wrinkled area)

Non operational area (sealed with transparent enclosure)

Waste gas parameters of immersion glue production line

	Planned air volume (m³/h)	Composition of exhaust gas	Exhaust gas concentration (mg/m ³)	Temperature and humidity	Emission method	Collection method	Raw material usage (Day * 1 line)
Nitrile gloves	8000~10000	Metanol	10~4050N	Normal atmospheric temperature Normal pressure	Continuity	Unorganized Capture	Methanol: 1 ton
Latex gloves (foam, looped)	8000~10000	Methanol, ammonia, acetic acid, xylene	10~4050	Normal atmospheric temperature Normal pressure	Continuity	Unorganized Capture	Methanol: 1 ton Xylene: 400kg Other negligible

Overall governance route

Front end exhaust gas collection system

1. Add collection pipelines to VOCs emission areas

The dispersion area includes methanol area, impregnation area, wrinkling area, and main drying area with additional collection pipelines. The main oven is pumped into a slightly negative pressure state;

2. Add manual air valves to each escape zone

Add manual air valves to the dispersion area to balance the extracted air volume in each area;

3. Increase the main exhaust fan

Add one waste exhaust fan to each glove production line, manually controlled by variable frequency, which can match the air volume according to energy consumption and workshop environment requirements;

4. Add electric valves for supervisors

Increase the linkage between the main electric valve and the fan;

5. Make partitions in the dipping area

Open the sliding door at the adhesive position on the operating surface, install an external observation glass, seal the non operating surface directly, and perform secondary subcontracting on the outside;

6. Overall planning of exhaust gas pipeline

All production lines are consolidated to RTO exhaust gas inlet;

Gaomi Yishou Gloves Co., Ltd

Gaomi Yishou Gloves Co., Ltd. was established in 2009 and is a modern enterprise specializing in the research and development, production, and sales of adhesive labor protection gloves.

rto for gloves

The company is located in the Economic Development Zone of Gaomi City, Shandong Province, known as the hometown of labor protection products. After more than two years of development, the factory covers an area of 35 acres and has four fully automatic impregnated glove production lines, with a preliminary production capacity of 35 million pairs of gloves per year. The product has three major series: nitrile, latex, and PVC rubber. Immersion gloves use a large amount of chemical additives in the production process, which contain harmful VOCs such as xylene, methanol, acetic acid, and ammonia. The above exhaust gases not only affect the health of employees and cause air pollution, but also lead to the dispersion and waste of raw materials.
