Eia ka mea pono e ike:

You use recycled materials to make new things. You must check quality at every step. Good preparation helps you get the best results from extrusion.

Shredding and Melting

Shredding into Flakes

You break the clean, dry plastic into small pieces. Shredders cut the plastic into flakes. These flakes look like tiny chips. Shredding helps the plastic melt faster. It also makes it easier to handle. You can use single-shaft or double-shaft shredders. Each machine works quickly. The flakes stay the same size. Uniform flakes help the melt stay smooth. This lowers the chance of blockages in the extruder.

Manaʻo kōkua: Smaller flakes melt faster and more evenly. This makes the recycled plastic better.

Melting and Degassing

After shredding, you put the flakes in an extruder. Hoʻomaʻamaʻa ka extruder i ka plastic. Huli ia i wai mānoanoa. Pono ʻoe e wehe i ka makū a me nā kinoea mai ka heheʻe. Inā ʻoe e waiho iā lākou i loko, hiki i nā ʻōhū a i ʻole nā ​​wahi nāwaliwali.

Hoʻomaʻemaʻe nā ʻōnaehana hoʻoheheʻe i ka plastic i hoʻoheheʻe ʻia. ʻElua ʻano puka makani nui: ka lewa a me ka hakahaka. Huki kēia mau puka makani i ke kinoea a me ka makū i ka hehee ʻana o ka plastic. Hoʻopili ka kānana i nā mea haumia paʻa. Hoʻoheheʻe homogenization hui i ka plastic. ʻO kēia ka mea e nānā a maʻalahi.

Eia kahi papa e hōʻike ana i ka hana ʻana o kēlā me kēia kaʻina hana:

Hiki iā ʻoe ke hoʻohana ʻenehana holomua e hoʻomaikaʻi i ka degassing. Hoʻohana kekahi mau ʻōnaehana i ka vacuum a hoʻoneʻe i nā mea haumia. Eia ʻekolu laʻana:

Mālama nā ʻōnaehana hoʻoheheʻe a me ka hoʻoheheʻe ʻana i kāu plastik recycled maʻemaʻe a ikaika. Loaʻa iā ʻoe nā huahana maikaʻi a kōkua i ka pale ʻana i ke ʻano.

Extruding Recycled Plastic: Ke Kaʻina Hana

Ka hānai ʻana i nā Pellets i loko o ka Extruder

Hoʻomaka ʻoe i ke kaʻina extrusion ma ka hānai ʻana i nā pellets i loko o ka extruder. Loaʻa kēia mau pellets mai nā ʻōpala plastik i hoʻohana hou ʻia āu i hoʻomaʻemaʻe a hoʻomaʻemaʻe ʻia. ʻO ka extruder he mīkini me kahi pahu lōʻihi a me kahi wili i loko.
