Everyone knows that the kitchen is a major place for home cooking. Therefore, when decorating the kitchen, all aspects must be taken into consideration, especially the kitchen floor. In addition to the aesthetic characteristics, we must also consider the moisture-proof, fireproof and antifouling aspects of the floor. Here we introduce: kitchen floor shopping skills and maintenance knowledge.
Kitchen Flooring Tips:
1, moisture resistance
The kitchen is a very humid place, and the water vapor is one of the invisible killers of the wooden floor. Floors with poor moisture resistance, once the moisture enters, will cause edging, swelling, corrosion and other phenomena, and damage the life of the wooden floor. Therefore, when choosing a kitchen floor, be sure to choose a floor with good moisture resistance. When paving, use a special moisture-proof floor mat to increase the moisture resistance of the kitchen floor.
2, fire resistance
The kitchen is equipped with wooden floors and it is very important to prevent fires. Choose a wood floor for the kitchen, use a floor with good fireproof performance, and apply additional fire-retardant paint. It is recommended to add 5-6 times of fire-retardant paint to the wood floor. When purchasing flooring, it is also possible to test the fire performance of the floor by means of burning with a lighter.
3, wear resistance
Kitchens are often stepped on, sometimes bumped and scratched, so they require high wear resistance on the floor. The laminate flooring has high wear resistance, and the general wear resistance index can reach 4000 revolutions to meet the demand. Solid wood flooring and engineered wood flooring wear resistance is slightly poor, if you choose, you need more careful maintenance.
4, stain resistance
The particularity of the kitchen space makes it easy for the kitchen floor to become "dirty." Adding dirt, leaves, and other difficult-to-clean rubbish makes the antifouling properties of the floor particularly important. When purchasing a kitchen floor, routine testing methods (such as writing with an oil-based pen) can be used for testing.
Kitchen floor care:
1, moisture prevention work to do a good job
Moisture is one of the biggest killers of the floor. Moisture can cause a "destructive" blow to the wooden floor. To prevent moisture in the kitchen floor, first of all, the pavement, reasonable materials and paving can do more with less. Second, we must always pay attention to the cleanliness and ventilation of the kitchen floor. If we accidentally sprinkle water, we must clean it in time.
2, stains need to be cleared in time
In the kitchen, accidental splashes of oil, vinegar, etc., if not cleaned, will cause varying degrees of damage to the wooden floor. For a long time, it is easier to produce scars on the floor, affecting the appearance of the ground. If oil stains on the wooden floor are difficult to clean, wipe with warm dilute bleach.
3, the correct cleaning and maintenance
In the daily maintenance of the floor, cleaning attention to control the amount of water. Do not use water or damp mop to mop the floor to avoid excessive humidity. The floor that is wiped is best to open doors and windows immediately to allow the air to circulate and dry the floor. The wooden floor waxes every two weeks or one month, and regular maintenance of the floor is also possible.
4, eliminate heat and fire
Overheated soup pots, kettles, etc. should not be placed directly on the wooden floor, it is easy to cause burns. It is even more difficult to use naked flames directly on wooden floors, which will not only cause damage to wood floors but also cause fires. If the floor is burned, a slight discoloration can be dripped with two drops of cooking oil and gently wipe it to restore it.

With the continuous development of drilling production, the use conditions of drilling rigs have become more and more diversified, and various types of drilling rigs have appeared accordingly. Factors affecting the type and composition of drilling rigs include drilling method, drilling depth, borehole size and drilling tool size, and drilling area conditions (such as electricity or fuel, transportation, and meteorological conditions).
1. According to drilling method
(1) Impact drilling rigs, such as wire rope impact drilling rigs (drilling rigs), vibration drilling rigs, etc.
(2) Rotary drilling rigs, such as those used in rotary drilling.
(3) Downhole power drilling tools, such as rotary drilling tools, turbo drilling tools, screw drilling tools, electric drilling tools, etc.
2. Divided by drilling depth
(1) Ultra-deep well drilling rig. It adopts a drilling rig with a diameter of 114 mm drill pipe, a nominal drilling depth range of more than 7000 meters, and a maximum hook load of more than 4,500 kN.
(2) Deep well drilling rig. The drill rod is 114 mm in diameter, the nominal drilling depth is 4000-7000 meters or more, and the maximum hook load is 2250-4500 kN or more.
(3) Drilling rigs for medium and deep wells. It adopts a drilling rig with a diameter of 114 mm drill pipe, a nominal drilling depth range of 1500-4000 meters or more, and a maximum hook load of 900-2250 kN or more.
Three, according to power equipment
(1) Diesel Engine-driven drilling rigs, which use diesel engines as power through mechanical transmission or hydraulic transmission.
(2) AC driven drilling rig, suitable for use in oil fields with industrial power grids.
(3) The drilling rig is driven by direct current, and the working unit is driven by a direct current motor.
Fourth, according to the driving mode
(1) Drive alone. Each working machine is driven by generators of different sizes, which are mostly used for electric drive. The transmission is simple and easy to install, but the power utilization rate is low and the total equipment mass is large.
(2) Unified drive. The three working units of drawworks, drilling Pump and turntable are driven by the same power unit. Most drilling rigs use this scheme. The unified drive can also include only one drilling pump, and the other drilling pump is driven separately. The unified drive drilling rig has high power utilization and can be adjusted mutually when the engine fails, but the transmission is complicated, installation and adjustment are troublesome, and the transmission efficiency is low.
(3) Group drive. The combination of power is between individual drive and unified drive. There are two options for three working machines. The power utilization rate of this kind of drilling rig is higher than that of a single drive, and the transmission ratio is simple to drive in a unified manner. Two sets of working machines can also be installed on different heights and scattered sites.
