Burada sicakligin 23-30 °C araliginda, tercihen 23 “C, oldugunun teyit edilmesi gerekmektedir. In the method of the invention, first of all, the weight adjustment of the polyol in the mixing tank is being done. Here, the temperature is between 23-30 °C, preferably 23 °C. Next polyola The cell angle is added at the rates indicated in Table 1 and are mixed. Afterwards, bentonite is added to the mixture and the mixture is mixed for another 20 minutes. are mixed. In this step, bentonite is added to the polyol with a screw system. required. Otherwise, homogenization cannot be achieved in the mixture. In this situation, It can cause regional agglomeration in bentonite polyol. This is also printed on the mold that uniform swelling does not occur in all parts of the material, (nozzle clogging source) causes mixing problems and the production of defective products. In short Here, homogenization is important. After homogenization The temperature of the resulting mixture is preferably measured with the aid of a thermocouple. Here It is necessary to confirm that the temperature is in the range of 23-30 ° C, preferably 23 “C.
Bunun ardindan enjeksiyon kaliplama yöntemi kullanilarak polyol karisim ve MDI izosiyanat basinçla kaliba enjekte edilmektedir. Bu adimda uygulanan basinç 130-170 Pa araliginda, tercihen 160 Pa, olmaktadir. Son olarak malzeme kalipta bekletilmekte ve reaksiyonun tamamlanmasi saglanmaktadir. Burada bekleme süresi 220-280 saniye, tercihen 4 dakika, olmaktadir. Kalibin açilmasiyla bulus konusu yönteme uygun olarak üretilmis poliüretan parça edilmektedir. After that, polyol mixture and MDI using injection molding method. The isocyanate is injected into the mold under pressure. The pressure applied in this step is 130-170 Pa in the range, preferably 160 Pa. Finally, the material is kept in the mold and reaction is completed. Here, the waiting time is 220-280 seconds, preferably 4 minutes. By opening the mold, in accordance with the method of the invention. The produced polyurethane is shredded.
Bulus konusuyla gelistirilen ürünle özellikle içten yanmali araçlarda motor üstü ve etrafinda titresim sönümleme ve araç içine motor sesinin araç içine daha az gelmesi saglanmaktadir. Regülasyonlar geregi gazlar belirli periyotlarla dogaya zarar verdigi için degismektedir. Bentonit kullanarak uzun süre herhangi bir proses degisikligine gitmeden sürdürülebilir bir üretim saglanmaktadir. Sisirici ajanlarin yanici ve patlayici özelligi sistemden bertaraf edilmistir; çünkü bentonit için böyle bir yanici etki söz konusu degildir. With the product developed with the subject of the invention, especially in internal combustion vehicles, vibration damping around and less engine noise inside the vehicle is provided. As required by the regulations, gases damage nature periodically. is changing. Using bentonite for a long time without any process changes sustainable production is ensured. Flammable and explosive properties of the inflating agents removed from the system; because there is no such flammable effect for bentonite.
