Home improvement "incurable diseases"
1, home improvement project "layer subcontracting"
With the changes in the concept of consumer spending, home improvement companies have become a trend. Some of the former decoration workers, who were once called “marathon guerrillas,†have accumulated experience and experience. After the funds, one after another went to the industrial and commercial department to register and set up the company. However, consumers are increasingly demanding home improvement company brands and services and do not look at small and medium-sized decoration companies. This group of people found that their prospects did not change after the establishment of the company, so many people went to the brand decoration company as project managers.
Although many decoration companies now claim to not subcontract, the actual project manager's management of construction workers is relatively flexible. Almost every project manager has a contact with a group of workers in his or her hands. Usually there is no salary payment and no employment contract. When a project starts, the project manager calls the worker by telephone.
Among these workers, quality is good or bad, and some workers are serious and responsible. They are not inferior to decoration companies. However, if the construction quality is not good, the interests of consumers will not be guaranteed. It is recommended that the majority of property owners should not rely on the home improvement company that sells on the door, let alone the low price of the “guerrilla guerrillasâ€. They should go for more, see more, and more than one. After determining the decoration company, they must first look at their business licenses. With the qualification certificate, when signing the contract, it is required to provide a home-installed contract printed by the country, avoiding loopholes in the contract and eliminating worries.
2, home improvement environmental protection "complaints first"
In recent years, with the fiery home improvement market, environmental protection issues have become increasingly prominent, and various types of disputes and deaths caused by renovation pollution have frequently occurred. A considerable number of consumers lack comprehensive and specific environmental protection knowledge. This has made home improvement companies and guerrillas with irregular operations take advantage of difficulties because of the long duration of home improvement, complicated processes, and mixed material markets. Pollution and environmental protection indicators exceeded.
According to the survey, 68% of the diseases are related to indoor air pollution, and 9% of children with leukemia have recently undergone renovations at home. 65% of fetal malformations are due to excessive formaldehyde in the room. Home improvement environmental protection is increasingly concerned by the people.

Organic compounds may be classified in a variety of ways. One major distinction is between natural and synthetic compounds. Organic compounds can also be classified or subdivided by the presence of heteroatoms, e.g., organometallic compounds, which feature bonds between carbon and a metal, and organophosphorus compounds, which feature bonds between carbon and a phosphorus.
Another distinction, based on the size of organic compounds, distinguishes between small molecules and polymers.
Compounds that are prepared by reaction of other compounds are known as "synthetic". They may be either compounds that already are found in plants or animals or those that do not occur naturally.
Most polymers (a category that includes all plastics and rubbers), are organic synthetic or semi-synthetic compounds.
Many organic compounds-two examples are ethanol and insulin-are manufactured industrially using organisms such as bacteria and yeast. Typically, the DNA of an organism is altered to express compounds not ordinarily produced by the organism. Many such biotechnology-engineered compounds did not previously exist in nature.
