Plastiki ya mashine ya pelletizing kama kifaa muhimu cha kuchakata tena plastiki inahitaji kufanywa kando wakati wa kushughulika na nyenzo laini na ngumu. Kwa nini vifaa vya laini na vifaa vya ngumu haviwezi kuchanganywa na pellets? Hebu tuchunguze suala hili kwa kina pamoja.
Differences Between Soft And Hard Materials
Kuna tofauti ya wazi kati ya nyenzo laini na ngumu katika suala la mali ya mwili na kemikali:
- Soft material characteristics: such as polyethylene (PE) and other soft plastics usually have a soft, bending, stretching, etc., its molecular structure is loose, and easily to be affected by heat and softening.
- Sifa za nyenzo ngumu: kama vile polypropen (PP) na plastiki zingine ngumu kawaida huonyeshwa na ugumu wa hali ya juu, nguvu ya mkazo wa nguvu, si rahisi kuharibika, nk, na muundo wao wa Masi ni mnene, na kiwango cha juu cha kuyeyuka.
Challenges in Pelletizing Machine Plastic Operation
Wakati wa mchakato wa pelletizing, tofauti kati ya nyenzo laini na ngumu inaweza kusababisha shida zifuatazo:
- Tofauti katika sehemu myeyuko: Viini vya kuyeyuka vya nyenzo laini na nyenzo ngumu ni tofauti sana, na hivyo kufanya iwe vigumu kusawazisha viwango vya joto vya pellet kwa zote mbili.
- The difference in fluidity: Soft materials and hard materials have different fluidity, which may lead to uneven material and poor fluidity when mixing and pelletizing in the same pelletizing machine plastic.
- Ugumu wa Ukingo: Mahitaji ya ukingo wa nyenzo laini na ngumu pia ni tofauti na kuchanganya na kutengeneza pelletizing kunaweza kusababisha ugumu wa ukingo au kupungua kwa ubora wa bidhaa iliyokamilishwa.
Summary: Separate Granulation To Ensure Product Quality
Tofauti kati ya vifaa vya laini na ngumu ni kwamba haziwezi kusindika wakati huo huo katika mchakato wa pelletizing. Kwa hivyo, ili kuhakikisha ubora wa bidhaa na ufanisi wa uzalishaji, nyenzo laini na ngumu lazima zipigwe kando na kutibiwa kibinafsi kulingana na sifa na mahitaji yao. Hii itahakikisha kwamba bidhaa ya mwisho ya pelletized ina ubora thabiti na athari nzuri ya ukingo, hivyo kuleta manufaa zaidi kwa wateja.
