Kusiyana pakati pa puffing makina ndi extruder

1, Tanthauzo ndi mfundo ntchito ya puffing makina ndi extruder
Makina opukutira ndi ma extruder ndi zida zomwe zimagwiritsidwa ntchito kwambiri pamakampani opanga pulasitiki komanso mafakitale opanga zakudya. Ngakhale pali kufanana pakati pa awiriwa, kusiyana kwawo kofunikira kudakali kwakukulu.

Makina opukutira amagwiritsa ntchito kutentha kwambiri komanso kuthamanga kwambiri kuti atulutse nthunzi wambiri wamadzi nthawi yomweyo, zomwe zimapangitsa kuti zinthuzo zikule ndikupunduka, kupanga zakudya zodzitukumula zokhala ndi voliyumu yayikulu, mawonekedwe otayirira, kukoma kowoneka bwino komanso kofewa, komanso kugaya mosavuta ndi kuyamwa, monga monga corn flakes ndi popcorn, zomwe ndizofala kwambiri zakudya zofunkhidwa. Mfundo yogwiritsira ntchito makina otukusira ndikutenthetsa zinthuzo pansi pamikhalidwe inayake, kuchititsa kuti mpweya wake wodzaza ndi nthunzi ukuchuluke mosalekeza, kupitirira kukana kwazinthuzo ndikuyambitsa kuwonongeka. Kenako, nthunzi ya chinyezi imakula nthawi yomweyo, zomwe zimapangitsa kuti zinthuzo zisokonezeke ndikukula nthawi yomweyo, motero zimakwaniritsa kutukusira.

Extruder ndi ndondomeko ya Kutentha ndi kusungunuka pulasitiki, ndiyeno extruding izo ku nkhungu zitsulo pansi kuthamanga kwambiri kutulutsa akalumikidzidwa pulasitiki mankhwala ndi mapaipi, monga zodzikongoletsera, zidole, etc. Mfundo ntchito ya extruder ndi: pambuyo Kutentha ndi mipope. kusungunuka, zinthu za thermoplastic zimatulutsidwa kuchokera kumutu wa nkhungu kudzera pakukakamiza kokakamiza. Chifukwa mkulu extrusion kuthamanga, zinthu extruded ali obalalika boma, ndiyeno mosalekeza anatambasula monga nkhungu akutsika, kupanga ankafuna Mzere kapena zozungulira m'mimba mwake perforated mankhwala pulasitiki.

2. Kusiyanitsa pakati pa makina opumira ndi extruder
Kusiyanitsa kwakukulu pakati pa makina opukutira ndi ma extruder kuli mu mfundo zawo zogwirira ntchito, kuchuluka kwa ntchito, ndi zida zopangira.
1. Mfundo zosiyana zogwirira ntchito
Makina opukutira amapangidwa ndi kutulutsa ndi kupaka chinyezi mkati mwa zinthuzo pansi pa kutentha kwakukulu ndi kupanikizika, pamene extruder imapangidwa ndi spiral extrusion mkati mwa pulasitiki.
2. Zosiyanasiyana zogwiritsira ntchito
Puffing makina makamaka oyenera kubala zakudya zodzitukumula monga chimanga flakes, vwende mbewu, etc. Ndipo extruders ndi makina ambiri, monga zida zofunika popanga mankhwala pulasitiki, chimagwiritsidwa ntchito m'minda monga zomangamanga, chakudya, ulimi, etc.
3. Zosiyanasiyana zopangira
Makina opukutira amagwiritsidwa ntchito makamaka pokonza zinthu zachilengedwe monga njere, pomwe ma extruders amagwiritsidwa ntchito pokonza zinthu za polima monga PVC, PE, ndi zina.
