What are the measures to prevent noise hazards?

Using certain measures can reduce the intensity of noise and reduce noise hazards. These measures mainly include:

(1) Muffler. Controlling and eliminating noise sources is a fundamental measure to control and eliminate noise. The production equipment for reforming processes replaces equipment and processes that produce strong noise with low-noise or silent equipment or processes. Keeping noise sources far away from workers' working areas and residential areas is An effective means of noise control.

(2) Control the spread of noise.

Sound insulation. The source of noise is sealed with a suction material, a sound-absorbing structure and a sound-absorbing device to prevent noise from propagating. Commonly used sound insulation walls, acoustic enclosures, soundproof floors, doors and windows.

Muffler. Use sound-absorbing materials to pave the interior walls or hang them in the interior space. Can absorb radiation and reflected sound energy, reduce the level of noise in the propagation. Commonly used sound-absorbing materials are glass, slag wool, felt, foam plastic, cotton wool and so on.

Plan the plant area and factory buildings rationally. A good green protection zone should be set up around the workplace where there is strong noise, and sound absorption materials should be provided on the walls, top surface, and floor of the workshop.

(3) Adopt reasonable protective measures.

Use earplugs properly. Soundproof earplugs and earmuffs have certain soundproof effects. According to the size of the ear canal, a proper earplug can be selected, and the sound insulation effect can reach 30~4080Db, which has better barrier effect to high-frequency noise.

Reasonably arrange the labor system. The working day is wider than the rest time, the rest time leaves the noisy environment, and the working time of the noise operation is limited, which can reduce the harm to the human body caused by noise.

(4) Health care measures. Persons exposed to noise should be treated and observed, and severe cases should be removed from noise operations.

Persons with obvious auditory organ diseases, cardiovascular diseases, and neurological systemic diseases found in pre-employment medical examinations or regular medical examinations may not participate in the work of contacting with strong noise.

SPCP120

Solid-phase synthesis, as the key process in the production of Bio-pharmaceuticals, is widely used for the synthesis of peptides, deoxyribonucleic acid (DNA) and so on. The synthesis method is to bound the functional group such as methyl, hydroxymethyl on a bead, which primiarly is polystyrene microsphere with low crosslink.

excellent batch to batch reproducibility and consistency:The beads are strictly controlled by unique technology and verified SOP from the first step; that can guarantee the consistency of the particle size and crosslink degree to achieve the excellent batch to batch reproducibility in the scale production.
