Precautions of the plastic crushing and washing
There are also some precautions of the plastic crushing and washing, because of the different of plastic type, the processes of the plastic plastic are mainly separated to two types–hard material and soft material. Their washing and cleaning methed and equipment are certainly different.
In one hand, the waste crusher of soft material and hard material are different. Specifically, their blades are different. In the other hand, in the duration of the cleaning, the soft material like plastic woven bags are always floating on the surface of the water, we call them “flaoting material”, the hard plastic like PP flakes always sink under the water, we call them “sinking material”.
Secara umum, plastik keras lebih bersih dan menggunakan lebih sedikit air, sehingga tidak memerlukan tangki sedimentasi. (Tangki sedimentasi dapat dipompa keluar dan digunakan kembali setelah limbah telah mengendap, yang akan sangat menghemat air.) Namun, bahan yang mengapung sangat kotor, mereka memiliki banyak abu yang mengapung di atasnya dan permintaan airnya tinggi.
Saat ini, banyak negara melarang pembuangan limbah, jadi buatlah tangki sedimentasi dan peralatan penyaringan lumpur, maka air tersebut pada dasarnya dapat memenuhi standar nasional.
