Due to the seasonality of harvesting is necessary to create serious saw logs and veneer inventories of raw materials for wood processing enterprises. But the stockpiling of raw materials not only leads to the freezing working capital, but also for the inevitable decline in the quality of raw materials and even its loss. And it ultimately leads to higher prices for the cost of production. Reasons for which the decline in the quality raw materials as follows: End of the crack; Fungal and mold damage; Defeats nasekomymi. drevesinyPri natural drying of wood drying in the drying chamber outer surface of the timber quickly dries up, while the inner remains moist, while dried (outer) part of the wood shrinks. Accordingly, in the dried part of the stresses cause the cracks. Cracks in its turn contribute to the smooth penetration of fungal spores deep into the wood. The most intensive moisture evaporates from the end surface of the logs, which explains the formation of cracks in this area.
Defeats mushrooms and plesenyuDrevesina is a breeding ground for various fungi. For their development requires the optimal temperature and moisture content. The optimum temperature for most species of fungi is blue 26-27 C. The most favorable moisture for the development of fungi 35-80%. wood in most cases it has high water absorption rate, "Some types of mushrooms stimulate the development of strong blue wood-destroying fungi. The development of wood-destroying fungi occurs at a temperature from 2 to 35 C, humidity of 20% wood.
Crisis in the yard all been waiting for cheap windows, but not so easy, prices rise and vice versa is likely to grow further. On the background of the crisis taking place here in Russia are increasingly offering so-called "object systems". They can called by different names – lightweight, light, corporate or tender, but the quality is different and it is a specialized systems with a reduced thickness of the outer walls of the profile. The fact that they appeared and offered on a window market can be easily explained. Manufacturer seeks to produce the maximum number of profile with decreasing its expenses, and as a rule, the calculation is carried out in linear meters, and not by weight profile. Most consumers will not notice the difference in thickness of the walls, think of some tenths of millimeters, but the difference is and it is very important and has implications for both the customer and the producer or window ie the company is an actual deterioration in the quality profile, or product. What happens? The client receives a box of economy – the class with the following deficiencies: – deterioration in the quality of welds due to thin walls and they become more brittle.
– Reduced resistance (stiffness) of the profile (windows) to the temperature changes with changing weather conditions during the year. – The use of lightweight reinforcement. – Deteriorated rigid fixation hardware window, ie in reduced operational safety box. – Poor quality installation of windows, especially in winter tk profile at this time of year is very vulnerable and may just crack and break away when struck. When carrying out installation work hard to put a window in the opening level unnecessarily profile all curved (wave), and is the most important cycle of mounting box.
– Increase in complaints. We have repeatedly offered a lightweight profile, and why – we answer, he is thin-walled. A you remove the stickers, attach the other – we retort. That's how we sell the profile. And from such grief – manufacturers that by lowering prices and a temporary increase in turnover suffer conscientious window company.
