Several issues that need attention when cotton topping
In order to top up at the right time, we must adhere to the principle of “when the time is not equal, and the branches are not equalâ€. No matter how high the plant is, it must be topped in time.
At present, waterproof
roof coating and Bridge Deck Waterproofing
mostly use a combination of polyurethane waterproof coating and waterproofing
membrane. Although it can achieve a certain waterproof effect, there are still
many problems.
UMS-AUPT
polyurea elastomer waterproof coating replaces other traditional waterproof
layer, not only solves the problem of poor adhesion between polyurethane
waterproof coating and waterproofing membrane, lap joint between coils, sealing
of waterproof coating and long construction period And technical problems such
as environmental pollution caused by waterproof coatings during construction.
The Roof Waterproof Coating and bridge
preservation waterproof. And UMS-AUPT brushed polyurea waterproof
coating system can be used to complete the durable waterproofing easily and
efficiently.
UMS-AUPT
polyurea elastomer waterproof coating has excellent performance:
1. It has strong
adhesion, can be attached to almost any substrate and is easy to apply. It can
be used on different substrates such as concrete, metal, wood and plastic.
2. UMS-AUPT
brushed polyurea elastomer jointless coating system for Waterproof Roof , the tensile strength is large, and the most
chaotic parts such as roof margin, skylight and air conditioning well can also
be used.
3. The
construction speed is fast, the whole waterproof layer can be integrated into
one body, completely preventing the immersion of harmful media, and greatly
prolonging the service life of the concrete structure.
4. It has good
weather resistance, excellent UV resistance, high process tolerance in outdoor
low temperature environment, and can close concrete cracks up to 10 mm.
5. Good
environmental adaptability, no VOS emission during construction, and solve
technical problems such as environmental pollution during construction.
The two majestic
constructions of Astana, the new capital of the Republic of Kazakhstan, are
excellent, for example, including the largest mosque in Central Asia. This
magnificent building can accommodate more than 5,000 people in the main hall,
the dome is 40 meters high, and there are four minarets. Polyurea Roof Coating, which can taste the cold test
of minus 50 °C.
A similar
solution was chosen for the opening and closing of the Astana Stadium. The
stadium covers an area of 10,000 square meters and can accommodate more than
30,000 spectators. The two special construction projects are intended to be a
complete success, and it is abundantly proven that polyurea coatings can remain
stable even under extreme climatic conditions, and this coating system will
continue to open up new uses.

2. The topping time generally starts from July 5th to July 10th and ends on July 15th.
3. Topping method: manually remove the two leaves and one heart at the top of the cotton plant, and bring out the deep burial of the land to prevent the spread of pests and diseases. It is generally required to retain 8-9 fruit branches, and the plant height should be controlled at 65-70cm. For the cotton fields with strong growth, it is necessary to carry out artificial sticks in advance, retain 2-4 camp-like branches, and cut empty branches and alfalfa buds. In order to improve the ventilation and ventilation conditions in the field, promote cotton early maturity.
