Description:
Chitin is a naturally occurring polysaccharide found in the shells of living organisms such as crabs, lobsters, tortoise, shrimps, and insects or it can be generated via fungal fermentation processes. And chitosan is a unique biobased polymer that is a derivative of chitin and forms the exoskeleton of arthropods. It is obtained by partial deacetylation of chitin using a chemical method or by enzymatic hydrolysis. In general, chitin with a degree of deacetylation of 70% or above is considered to be chitosan.
Application:
Chitin and its derivative chitosan are natural biopolymers which are extracted from crabs, prawns, and shrimps. Chitin consists of �²-(1,4)- linked 2-acetamido-2 deoxy-�²-D-glucose which is insoluble in water and hydrophobic in nature.
Chitin is a natural biopolymer, which is biocompatible and biodegradable and useful in many applications like biomedical, electronics, photography, and textiles. The main advantages of chitin and its derivates are the low cost and easily availability. The chitin-based composites like chitin beads, chitin nanofibers, and chitin hydrogels are used in drug delivery and tissue engineering applications. In recent times, chitin and its derivates have gained much importance in the field of electronic applications as sensors and energy storage applications. Chitin nanofiber papers are being used as flexible green electronics in solar cells and organic light-emitting diodes. Aksoy et al. prepared low-cost chitin derivatives with high conductivity, for the construction of Schottky diodes, which are useful for photoelectrical applications. Schauer et al. reported a variation of the piezoelectric effect of the chitin electrospun nanofibers.
1. Description: It is the raw material for making thermosetting resin, light curing epoxy resin coating, oil resistant coating and drying coating. Its copolymer emulsion is used for fiber finishing, fabric, leather and paper coating. Also used as wood, metal and other adhesives.
2. Typical recipes
Used as crosslinked monomer in acrylic emulsion. The amount of carboxyl-containing acrylic emulsion pressure-sensitive adhesive is L % ~ 2% of the total monomer mass, and the initial adhesion will be greatly reduced if it exceeds 3%. For emulsion adhesives without carboxyl group, the general dosage is not more than 5%. The crosslinking reaction temperature of MMAM alone is high, generally 120 ~ 170�??�?�ºC, and the addition of protic catalyst can reduce the crosslinking temperature. Acrylic acid (AA) can both provide hydrogen protons and copolymerize with acrylates, so MMAM should be used as a composite crosslinking agent with AA at a dosage of 3:2. Cross-linking agent HA can replace N- hydroxymethyl acrylamide, and does not contain formaldehyde.
3. Application scope
A. Can be used as crosslinking agent, widely used in fiber modified resin, processing dyes, plastic adhesives, soil stabilizers, etc.
B. Used for fiber modification, resin processing, adhesives and paper, leather, metal surface treatment agent.

This equipment is a four-channel embedded digital hard disk video recorder designed for automotive safety. It is embedded processor and operating system, combining video / audio compression / decompression, gps, vehicle recorder, high capacity hard disk storage technology, the system has high intelligence and high stability. Used in bus, ship, train, and other areas for security.
This Audio/Video Recording Pen appears to be a high quality, stylish writing instrument, and it is.
But looks can be very deceiving, because this pen also conceals a 1 mega-pixel video camera and DVR! You simply push one button and digital video begins to record onto the built-in 8GB memory chip.
Slide the pen apart to expose a USB port, allowing fast downloading of data and making charging the device very simple. A compact built-in battery cell delivers power for three hours on a full charge, putting two hours of covert video surveillance at your fingertips!
This unit features the latest technology that you wont find in any other DVR pen. Not only can you set it to record audio and video, you can switch over to audio only mode, motion activation, or even adjust the resolution that the device records in. Record any video and audio evidence instantly.
The Digital Video Pen works as a 4 / 8 / 16 GB USB drive and is plug & play compatible, with a built-in rechargeable Lithium-ion battery.
The small pinhole camera can be used secretly for any law enforcement or personal covert mission.
Students can also use this camcorder to record lessons and tutorials.
Its highly sensitive microphone can clearly capture sounds in a 15 square meter area.
