As the temperature rises, the home improvement market is getting hotter. The survey found that many construction supervisors have at their disposal five or six sites at the same time, the most being ten. In order to catch up with the progress, coupled with the shortage of manpower, the barbarous decoration has risen. >>>Returning experience from a few thousand oceans: The packed guerrillas are good at doing evil The savage decoration is mostly "guerrilla" “As the decoration season begins, complaints from home improvement are also heating up.†According to the person in charge of the Consumer Complaint Consultation Station of the Hunan Provincial Interior Decoration Association, among the complaints that are effectively accepted, the majority of complaints concerning the quality of decoration and decoration are in the majority. . The person in charge analyzed that: “The complaints handled by the association involved the decoration company, especially the member companies, which can effectively solve it. However, this part of the complaints only account for about 40% of the total number of complaints, and most of the complaints are still concentrated on The guerrilla's brutal decoration." According to reports, the decoration "guerrillas" have mostly no fixed office space, and do not have industrial and commercial licenses, decoration qualification certificates, technical qualifications and other certificates. For consumers' complaints about the decoration of "guerrilla guerrillas", it is generally difficult for the association to safeguard its rights. Among the complainants, middle-aged and senior citizens accounted for the vast majority. Owners who lacked decoration experience often only paid attention to the decoration price issue, but they paid little attention to the issues concerning the decoration team's license and qualifications. Think twice and avoid savage decoration Home decoration is a complicated process. For the first time decoration of the owner, whether it is to choose the decoration company, the specific construction process or the acceptance after the renovation, each link must think twice and prevent the loss of their own interests. Experts reminded that for owners who have decoration requirements, the first thing is not to choose a decoration company. Instead, they should integrate their own needs, housing conditions, etc., and do a good job positioning the home improvement level. Then, according to the positioning of the renovation, choose the home improvement company of the corresponding grade. . "Renovation to find a formal home improvement company does not mean that the decoration is guaranteed. Some home improvement companies will sign home-made contract terms with the owners. This deserves the attention of the owners." Yao Baolin, president of the Provincial Interior Decoration Association, said that he should sign with the home improvement company. The residential decoration contract printed by the Provincial Administration for Industry and Commerce avoids the overlord clause in the homemade contract of the home improvement company. At the same time, for all renovation payments, the landlord should not pass the company finances directly to the project manager or others. Renovation acceptance ensures safety Construction is the most critical part of the renovation process, which directly determines the quality of the entire project and is also the most concentrated complaint. According to reports, for some concealed projects, such as pipe laying is not horizontal and vertical, and fixed with a pipe card; plastic pipe embedded in the wall and the ground is protected with cement mortar, and can prevent the kick crack; electrical circuit decoration process is Reasonable, etc., these owners are generally difficult to ponder clearly, it is best to ask a professional acceptance master to accept the decoration of the house. "The decoration security problem must not be underestimated, the house after acceptance is not qualified, resolutely not staying." Yao Baolin reminded consumers that in the face of brutal decoration, the industry dares to say no. Experience talk about home improvement decoration interior decoration house decoration decoration company The preparation technology of Si3N4 ceramics has developed rapidly in the past few years. The preparation process mainly concentrates on reaction sintering method, hot pressing sintering method, atmospheric pressure sintering method, gas pressure sintering method, etc. Due to different preparation processes, various types of Silicon Nitride Ceramics have Different microstructures (such as porosity and pore morphology, grain morphology, intergranular morphology, and intercrystalline second phase content). Therefore, the performance varies greatly. In order to obtain Si3N4 ceramic materials with excellent performance, high-quality Si3N4 powder should be prepared first. The quality of Si3N4 powder prepared by different methods is not exactly the same, which leads to the difference in its application. The failure of many ceramic materials is often attributed to Developers do not understand the differences between various ceramic powders and have insufficient knowledge of their properties.
