Portable  Gas Detector

  SiH4 Silane

Silane (SiH4) is a colourless, flammable gas with a sharp, repulsive smell similar to that of acetic acid. It is pyrophoric gas meaning it can spontaneously combust and has a a wide flammable range 1.37 to 96% in air.

The greatest hazard of SiH4 is its unpredictable behaviour when released to the air with either delayed ignition, immediate ignition or no ignition. Most accidents occur due to ignitions/explosions caused by poor process handling and the pyrophoric nature of Silane. Changes in cylinder pressure, flow rate, confinement area, humidity, impingement on objects, etc. can cause ignition.

Water repellents, bio-inert layer on titanium implants, masonry protection, control of graffiti, applying polycrystalline silicon layers on silicon wafers when manufacturing , semiconductors and sealants.
The semiconductor industry used about 300 metric tons per year of Silane in the late 1990s. More recently, a growth in low-cost solar photovoltaic module manufacturing has led to substantial consumption of Silane as part of the production process.

HiYi Technology offers single-gas detector or multi-gas detectors, workers can monitor exposure in areas where gases may be present. In areas where workers could be exposed to additional gases, the gas detector will keep workers safe.

XM-E Portable Gas Detector is a continuous monitoring of a variety of single gas detection equipment.

This product is suitable for environmental monitoring, industrial production and other harmful gases working environment, which can effectively protect the health and safety of staff is not compromised.It meets European standard gas detector.

Application Uses of Silane:

It is of practical interest as a precursor to elemental silicon. Several industrial and medical applications exist for silane and functionalised silanes. For instance, its used as coupling agents to adhere fibres such as glass fibres and carbon fibres to certain polymer matrices, stabilising the composite material. In other words, SiH4 coats the glass fibres to create better adhesion to the polymer matrix.

The detector can effectively predict the concentration of dangerous gas alarm, to ensure that the safety of staff life is not threatened, production equipment is not lost.
