Uglerod Tolasi Isitish Naychalari Zarba Mashinalari Oshirish Mumkin?

Plastic bottles are now widely used across various industries in daily life, including the beverage industry, daily chemical industry, food industry, household goods industry, and pharmaceutical and chemical industries. Plastic bottles have become the dominant type of container in contemporary society, having long replaced traditional glass or metal bottles. The production of plastic bottles requires PET multifunctional blow molding machines. The working principle of the blow molding machine is to heat the plastic preform to a certain temperature, and then use a special process to blow it into the desired shape and size. So, can uglerod tolali isitish quvurlari be used in blow molding machines? The answer is yes.

Shamollatish mashinalarida umumiy isitish quvurlari

Hozirgi vaqtda puflash mashinalarida eng ko'p ishlatiladigan isitish quvurlari volfram filamentli infraqizil isitish quvurlari hisoblanadi. Biroq, infraqizil isitish naychalarining kamchiliklari bor: volfram filamenti yuqori haroratlarda asta-sekin sublimatsiyalanishi va himoya gazidagi kislorod miqdori bilan reaksiyaga kirishishi tufayli isitish filamenti vaqt o'tishi bilan yonib ketadi, bu muqarrar masala.

Nima uchun uglerod tolali isitish quvurlari to'liq avtomatik puflash mashinalarida ishlatilishi mumkin?

1. O'xshash shakli va tuzilishi:

Uglerod tolali isitish quvurlari share the same shape and structure as infrared heating tubes. Both have similar external structures and materials, which can be made from either transparent quartz tubes or ruby quartz tubes. All the advantages of infrared heating tubes, such as acid and alkali resistance, high temperature tolerance, quick startup speed, and low thermal inertia, are also present in carbon fiber heating tubes.

2. Isitish elementlaridagi farqlar:

The key difference lies in the heating element material. Infrared heating tubes use tungsten filaments, while uglerod tolali isitish quvurlari use carbon fibers. Carbon fiber is a new material that has gained popularity in the last decade due to its excellent physical and chemical properties, and it is widely used in various fields. The biggest advantage of carbon fiber over tungsten filament is that under the protection of inert gas or in a vacuum environment, the physical properties of carbon fiber are much more stable—several times more stable than tungsten filament. This means that as long as the vacuum environment is maintained, carbon fiber heating elements can operate continuously, a significant advantage that tungsten filaments cannot match.

3. Spektral Ishlash:

Volfram filamentli infraqizil isitish naychalari, tashqi kvarts naychalari yoki boshqa parametrlar bilan sozlangandan so'ng, to'lqin uzunligini 1,06-1,2 gacha boshqarishi mumkin. Aksincha, uglerod tolali isitish quvurlari 1,5-15 radiatsiyaviy diapazonga ega. Ushbu to'lqin uzunligi diapazoni Plastmassalardagi funktsional guruhlar tomonidan so'rilgan infraqizil spektr bilan bir-birining ustiga chiqadigan maydonga ega, shuning uchun plastik tarkibiy qismlarni tahlil qilishda ko'pincha infraqizil spektrometrlardan foydalaniladi. Shuning uchun uglerod tolali isitish quvurlari plastik qismlarni isitish uchun ko'proq mos keladi.

Infraqizil isitish quvurlari hozirda juda yaxshi ishlayotgan bo'lsa-da, shuning uchun ko'plab ishlab chiqaruvchilar yangi uglerod tolali isitish trubkasi puflash mashinalarini joriy qilmagan bo'lsalar-da, asosiy tashvishlar isitish samaradorligi va ishlash muddati. Biroq, bu tashvishlar asosan keraksizdir.
