Momwe mungasankhire makina oyenera?

Zogulitsa zamapulasitiki zimagwira gawo lofunikira pantchito zosiyanasiyana za mafakitale ndi zaulimi komanso moyo ndi zinthu zawo zabwino monga kulemera kopepuka, mphamvu yayikulu, kukana dzimbiri, komanso kukonza kosavuta. Komabe, ndi kugwiritsidwa ntchito kwa zinthu za pulasitiki, kutaya zinyalala zakhala vuto lalikulu, pomwe "zovuta kunyoza mwachilengedwe" lakhala vuto losatha lomwe liyenera kuthetsedwa mwachangu pakuwononga zachilengedwe padziko lonse lapansi.

M'zaka zaposachedwa, ndikukula kwamsanga kwamakampani opanga mapulasitiki adziko langa, makampani opanga pulasitiki a granulator nawonso akula mwachangu. Granulator amatha kupanga zinthu zapulasitiki zobwezerezedwanso m'matumba apulasitiki kudzera munjira zosiyanasiyana kuti akwaniritse kukonzanso kwa pulasitiki. Makampani opanga granulator amaphatikizapo magawo ambiri azachuma mdziko lonse. Sichinthu chofunikira kwambiri pakupanga zinthu zambiri zamafakitale ndi zaulimi, komanso chimagwira ntchito yofunikira kuthana ndi kuipitsa kwa dziko langa, kukulitsa kuchuluka kwa zinthu zopangidwa ndi pulasitiki, ndikukhazikitsa dongosolo labwino lobwezeretsanso pulasitiki. .

Kwa makampani opanga mapulasitiki obwezerezedwanso, momwe mungasankhire pelletizer yoyenera kugwiritsa ntchito ndikofunikira kwambiri, chifukwa cholumikizira pulasitiki sichingathe kupanga mapulasitiki onse chifukwa cha kupsinjika kwapulasitiki kosiyanasiyana ndi kukakamizidwa kwa extrusion. Ma granulators wamba amatha kupanganso mapulasitiki a granulate m'moyo watsiku ndi tsiku, koma monga mapulasitiki ena apadera, monga pulasitiki ya uinjiniya, polyethylene yolumikizidwa pamtanda, nsalu zopota, ndi zina zambiri, ma granulators apadera amafunika kukonzanso ndi kusungunuka. Chifukwa chake, opanga amayenera kusamala mitundu yamapulasitiki yomwe amafunika kuyikonzanso akagula pelletizer, kenako ndikusankha pelletizer yoyenera.

Kuphatikiza apo, mukamagula granulator, muyeneranso kulabadira mfundo izi:

Fotokozani tanthauzo ndi cholinga chogula granulator. Pakadali pano pali mitundu itatu yamakasitomala omwe amagula ma granulators pamsika. Amayikidwa ndipo amayambitsidwa ndi makampani payekha kapena yabizinesi. Opanga pulasitiki amagula ma granulators kuti athetse vuto la zotsalira kuchokera kumafakitale awo. Ndiye pali ogulitsa ndi mabizinesi ogulitsa. Kwa makasitomala omwe amayamba mabizinesi awo kapena mabizinesi azinsinsi, ayenera kufotokoza mitundu ya pulasitiki yopangidwa ndi kampaniyo pogula pelletizer. Olemba ma pelletizers amatha kungobwezeretsanso ndikupanga mapulasitiki azolinga za PP ndi PE, zomwe zimakhalanso zopangira zapulasitiki pamsika wamapulasitiki. Msika wa thovu wa PS ndi wocheperako. Ngati pali njira yotsatsira yomveka yapulasitiki yapadera, ogwiritsa ntchito amathanso kugula ma pelletizers ofanana.

Ntchito ya granulator. Ma granulators amatha kugawidwa m'makina osakanikirana ndi mapira opota molingana ndi kuchuluka kwa zomangira. Pogwiritsa ntchito kagudumu kamodzi, pulasitiki imatumizidwa patsogolo mozungulira mbiya. Pogwiritsa ntchito kagwiridwe ka mapasa, pulasitiki imatumizidwa kutsogolo molunjika mbiya. Malinga ndi mfundo yogwirira ntchito, makina oyendetsa mapasa akaimitsidwa, zinthu zomwe zili mumakina zimatha kutulutsidwa, ndipo makina amodzi amatha kusungira zotsalira zochepa. Mapulasitiki ambiri amatha kupukutidwa, ndipo chopangira chimodzi ndi mapasa chimatha kugwiritsidwa ntchito popanda kusiyanitsa.

Komabe, popanga mapulasitiki obwezerezedwanso, chifukwa chakukula kwakukulu kwa mawonekedwe a nkhungu ndikusinthira kosavuta, makina osungunula amodzi ndiwothandiza kwambiri; popanga mapulasitiki osinthidwa, ma masterbatches amtundu, ndikupaka utoto wosakanikirana, zotsatira za makina awiriwa ndizofanana. ; Mukamapanga zingwe zazitali zazitali zamagalasi komanso zida zolumikizirana zapamadzi, zingagwiritsidwe ntchito ndi ma granulators amapasa okha. Kuphatikiza apo, potengera mtengo wogula kwamakina ndi mtengo wopanga pambuyo pake, mwayi wokhala ndi sikelo imodzi ndi wotsika kwambiri, pomwe zopukutira mapasa zili pachiwopsezo chachikulu. Chifukwa chake, pogula zida, m'pofunika kusankha zida zofananira kutengera ndi zinthu zosiyanasiyana zomwe zimapangidwa ndi kampaniyo.
