How to Remove Impurities On the Surface of Concrete?

 Impurities on the surface of concrete refer to liquids or solids that exist on the surface of concrete, which can affect the bonding and maintenance of floor coatings and concrete, or cause problems related to the use of floor coatings and concrete. Surface impurities must be thoroughly removed before construction.

Common Surface Impurities Include the Following:

1. The old coating, which is common in floor renovation projects, will be accompanied by oil stains.

2. Cement slurry, which is a thin layer formed by incompletely hydrated water slurry floating on the outer surface of the concrete. The reason is the continuous exposure of concrete constructed at lower temperatures.

In the air, or the concrete is plastered and pressed too much. The general floating layer is 1-2mm;

3. Concrete curing agent or release agent, or another contaminated grease.

Common Concrete Base Treatment Measures:

1. Shot blasting:

Shot blasting is the most effective, cleanest, and dust-free method for concrete. The shot-blasted concrete surface is clean and hard, and small cracks are easy to find. The concrete surface can be cut to 3mm thickness. It is suitable for large area use.

2. Grinding treatment:

Diamond abrasives are usually used, which can effectively remove local high points and surface impurities. YG Machinery has floor grinders specially used for processing concrete roads. Please contact us for the best quality and best price machines.

3. Milling treatment:

Suitable for concrete processing with old coatings or weak layers. It is suitable for partial treatment, and the later cost is high. YG machinery's floor scarifier machine can effectively remove impurities on the surface of the concrete, please contact us to know more about the machine.

4. Pickling treatment:

Pickling treatment will roughen the surface of the concrete, but it cannot remove laitance or other loose substances. Usually, a 10% hydrochloric acid solution is used. Combined with a high-pressure water gun, the effect is better. Suitable for local treatment.

What Should I Pay Attention To When Operating the Water Well Drilling Rig?

 1. When there is a drilling tool in the hole, the gyrator is not allowed to reverse, except for the action required by the prescribed procedure.

2. When the rotator is reversed to remove the drill rod, the oil cylinder must be left with enough unloading stroke to avoid damage to the drill rod thread.

3. During the working process of the water well drilling rig, attention should be paid to the temperature changes of the moving parts at any time. The temperature rise of bearings, gears, oil pumps, oil motors, motors, etc. must not exceed 45 degrees, and the temperature at the oil tank outlet must not exceed 60 degrees, otherwise, the machine should be shut down for inspection and processed;

4. Observe the oil return pressure gauge of the pump station, and find that when the oil return pressure exceeds 0.35Pa, stop the machine to replace or clean the filter;

5. When the drilling rig is working, pay attention to whether there is oil leakage in the components of the hydraulic system, hoses, and pipe joints. If there is any fault, it should be dealt with in time;

6. When the drilling rig is working, in addition to the corresponding changes in the oil supply pressure, rotation, and propulsion speed caused by the change in the drilling load, the sudden and large increase in system pressure causes a huge change in the rotation and advancement speed. The agricultural drilling rig should be stopped immediately, find out the reason. Deal with faults;

7. When the drilling rig stops working, all operating handles should be placed in the middle position.

8. When the drill pipe is normally withdrawn from the drill pipe, the drill pipe must be clamped with a clamp or a rod clamp, and the person taking the rod must leave a safe place 1m away from the drill pipe before calling the drilling rig driver to operate The regulations require the drilling rig to be driven to withdraw the drill pipe. During the process of retreating the drill pipe, the rod taker and the driver of the drilling rig must cooperate closely, take care of each other, concentrate their energy, and prevent misoperations and exceptions.

9. When the connecting joint between the hydraulic shaft and the drill pipe is seized and cannot use the rod clamp or rod clamp, use a pipe clamp to clamp the drill rod, and use an extension rod (0.5-1m) to connect the pipe clamp (increase the torque) ), manually loosen the joint of the drill rod.

10. When the connecting joint between the water shaft and the drill pipe is bitten and cannot be loosened by the manpower with the pipe wrench, the pipe wrench can be used to clamp the drill pipe. One end of the pipe wrench is close to the frame as a fulcrum, and the pipe wrench is fixed with an iron wire On the frame after the personnel in the drilling field leave the drilling field to a safe place, the drill pipe driver can start the drilling rig to reverse the drill pipe to prevent the pipe clamp from flying off and hurting people due to misoperation.

11. When the inclination angle of the drill rod is greater than 30°, the operator must not face the drill rod when dealing with broken drill rods to prevent the drill rod from slipping out during drilling and hurting people.

Types of Water Well Drilling Rigs

 

Water well drilling rigs can be divided into three main categories, rotary water well drilling rigs, impact well-drilling machine, compound well drilling rigs. Rotary water well drill machine can be divided into large and small pot cone drilling machines, positive and reverse circulation rotary disk drilling machine, hydraulic well drilling machine, DTH impact rotary drilling rig machine, etc…

The Working Principle of Rotary Water Well Drilling Rigs

It mainly relies on the rotary motion of the drilling tools to break rock strata and form holes. Simple rotary well drilling equipment has only a drilling device, while a well-structured model has drilling devices and circulating well-washing devices. The drilling tools of rotary table type drilling equipment includes drill pipe and drill bits. The diameter of the commonly used drill pipe has six kinds of 60, 73, 76, 89,102, and 112mm and the drilling bits can be divided into two categories, full drilling bits, and annular drilling bits.

Large And Small Pot Cone Drilling Machine

It mainly uses its pot taper drill tool to rotary and cut the soil layer. Depending on the size of the drill string, they can be called large pot cones and small pot cones, which can be driven by humans or power.

Positive And Reverse Circulation Mud Washing Rotary Disk Drilling Machine

It is composed of towers, a hoist, a rotary table, a drilling tool, a mud pump, a faucet, and a motor. When it works, the power machine drives the rotary table through the transmission device, and the drill bit is driven by the active drill pipe to rotate the broken rock layer at a speed of 30-90r/min.

Pneumatic Well Washing Rotary Drill Machine

It uses an air compressor instead of a mud pump to clean well. It usually adopts the reverse circulation method, that is, compressed air is sent to the gas-water mixing chamber in the well through the gas supply pipeline so that it can be mixed with the water flow in the drill pipe to form the aerated water flow with the proportion less than 1. Under the action of gravity of the annular water column around the drill pipe, the aerated water flow inside the drill pipe carries rock debris continuously up and out of the well and flows into the sedimentation tank. Then the precipitated water flows back into the well in a self-flowing manner.

Hydraulic Power Head Rotary Drilling Rig Machine

The type is driven by a hydraulic motor through a reducer. The powerhead moving up and down the tower is used to drive the drill pipe and drill bit to rotate and cut rock layers instead of the rotary disc and faucet. It is characterized by fast drilling speed, while the loading and unloading of drilling tools and the downhole pipe are relatively simple.

DTH Vibratory Rotary Well Drilling Machine

It is a kind of rotary water well drilling equipment that drills into rocks formations by the connection of vibration and rotary motion. The excitation force produced by the vibrator causes the whole drill string to make conical pendulum motion. The drill bits are placed on the outside of the vibrator shell through a friction ring set. On the one hand, it vibrates horizontally with the vibrator at a frequency of about 1000r/min. On the other hand, it rotates around the axis of the vibrator at a low speed of 3-12r/min to break the rock strata, while the drilling pipe doesn’t turn. The well is cleaned by means of compressed-air reverse circulation, and the cuttings are discharged out of the well through the pipe and drill pipe cavity at the center of the vibrator.

In recent years, nitrile gloves have been used more widely in industries such as housework, chemistry, aquaculture, glass, food, and scientific research. Since customers choose nitrile gloves, it means that they have higher requirements for quality and use environment. Therefore, the market and living space of low-end nitrile gloves have been shrinking, and the production and sales of nitrile gloves have gradually concentrated on middle and high-end products. The quality requirements for products are getting higher and higher.The production technology of nitrile gloves has been updated rapidly in recent years. The new production technology represented by the unilateral two-hand mold process has greatly improved the production efficiency and has also given new entrants a clear advantage in latecomer.

Nitrile Gloves Features:

1. Nitrile is a kind of rubber, mainly synthesized from acrylonitrile and butadiene, and is a key material for organic synthesis and pharmaceutical intermediates.
2. The nitrile glove model is divided into non-slip palm numb surface and hand tip numb surface non-slip, overall numb surface non-slip, generally no powder.
3. Nitrile gloves do not contain protein, amino compounds, and other harmful substances, and rarely cause allergies.
4. Nitrile gloves are degradable, easy to handle, and environmentally friendly.
5. The puncture resistance of nitrile gloves is three to five times higher than that of latex. For dentists who need to use sharp tools, durable nitrile gloves can create a safer barrier in contact with patients.
6. Fit hand shape. Due to its good thermal conductivity, which provides excellent flexibility, which is particularly important for medical professionals or those who operate small parts or tools.
7. The nitrile material can be added with pigments and the color is brighter. Can relieve the nervousness of patients.
