High
pressure injection technique characteristics
The
high pressure injection machine can produce high injection pressure,deliver
the chemical to the center of wall crack,the chemical diffuse
from center to all direction.The chemical fast react with water
and harden to plug up the crack permanently and rech water stop
effect surely.This constructing method use high pressure injection
machine, injecting high pressure,big flow,thus can stop the
water immediately. Especially for stop the big running water,
this method has its magic part.Its inject point is from the
center of the structure's crack, so it is effective. It is very
fast and efficient, especially for the cracks that is over 40cm
thickness' concrete wall. |

High
pressure injection Chemical characteristics
The chemical is multiple. Application
choice depends on the water leaking and crack condition.
Chemical can be classified into polyurethane and epoxy.
Polyurethane can be classified into single component and
two components. Its reacting speed and hardening time
depend on the quantity of added accelerator to adjust
its harden time. According to its hardening classified
elasticity and little elasticity water stopper ( Rigid
type). So you can have multiple choices. Under your professional
judgment and right choice, therefore you can suit the
remedy to the case, to get twice the result with half
the effort. |

Machine
High
pressure injection machine, injection pressure can reach 8000-10000
Lb, can inject into above 0.02mm hairline cracks.Transferable material
suction method: Besides traditional pour material method，this machine
can change to use hose suction method to feed-in material，which can
save the pouring material time and material.Except while installing
this rig，need to use cleaner to clean up material feed-in system and
suction hose right the way, to avoid chemical dried caused inside
blockage inside.
