ntchito

Crate ya pulasitiki ili ndi ubwino wake wokongola, kukana kwa dzimbiri, mphamvu zambiri, kusayamwa kwa chinyezi, khalidwe laukhondo, kuyeretsa kosavuta, kukonza kosavuta ndi kuumba, zomwe zimathandiza kupanga chitukuko, kasamalidwe kosavuta, mtengo ndi moyo wautali wautumiki.HDPE crate an m'malo milandu matabwa, makatoni ndi zotengera zina zoyendera ma CD, chimagwiritsidwa ntchito mu chakudya, chakumwa ndi mafakitale ena.Nthawi zambiri amapangidwa m'njira ziwiri.

1. Hot extrusion ndi ozizira kukanikiza akamaumba

Zida zazikulu zopangira mabokosi opangira pulasitiki ndi polyethylene yolimba kwambiri, copolymer polypropylene ndi polyvinyl chloride.Bokosi lachiwongola dzanja la pulasitiki limapangidwa ndi njira yotentha yotulutsa ndi kuzizira, yomwe ili ndi ndalama zochepa za zida, kugwiritsa ntchito mphamvu zochepa, mawonekedwe osavuta komanso zofunikira zaukadaulo, koma kuchita bwino kwambiri, kupangira zinthu movutikira komanso kusauka kwamakina, kotero sikumagwiritsidwa ntchito kwenikweni. kupanga.

Njira zamakono ndi motere: utomoni batching dyeing - "Sungunulani extrusion -" yosungirako yamphamvu kutchinjiriza - "kufa casting -" kumaliza.

2. Jekeseni akamaumba

Bokosi lachiwongola dzanja la pulasitiki ndi thireyi ya pulasitiki kuwonjezera pa kutentha kwa kutentha ndi kuzizira kozizira, njira yomwe imagwiritsidwa ntchito kwambiri ndi jekeseni, kuumba jekeseni kumatchedwanso jekeseni kapena jekeseni, mfundo yake ndi mfundo ya singano ndi njira yogwiritsira ntchito ndizofanana. , kotero anthu ena amatchedwanso ndondomeko jekeseni akamaumba.Kumangirira jekeseni ndikoyenera mitundu yonse ya ma thermoplastics ndi mapulasitiki ena a thermosetting.Pulasitiki ya ufa kapena granular kuchokera ku hopper ya makina a jakisoni mu mbiya kuti itenthetse, kuti pulasitiki isungunuke, malo othamanga ndi mapulasitiki abwino, ndiyeno mu plunger (kapena wononga) pansi pa kukankhira kwa nozzle kutsogolo kwa mbiya mu nkhungu patsekeke ndi kutentha otsika, pambuyo kuzirala ndi kutsegula nkhungu, mankhwala pulasitiki akhoza analandira.

Njirayi ili motere: kudyetsa - kutenthetsa plasticization - jekeseni - kuumba - demold.

Pakadali pano, makina omangira jekeseni omwe amagwiritsidwa ntchito kwambiri ndi makina opangira jekeseni yopingasa.jekeseni akamaumba zida ndalama ndi lalikulu, nkhungu kapangidwe zovuta, mkulu processing mtengo, oyenera kupanga yaikulu.
