He aha ka Mingshi Acrylic a me nā huahana Polycarbonate Extrusion

ʻO ka extrusion Acrylic/polycarbonate he kaʻina hana maʻamau maʻamau kahi e hoʻoheheʻe ʻia ai kahi mea polymer, i hoʻonui ʻia me nā mea hoʻohui i makemake ʻia, a hoʻoheheʻe ʻia i kahi kaʻina hana mau.

(1) ʻO ka mea mua, ʻo ka mea maka (polymer) i ke ʻano o nā granulates, ua hānai ʻia i ka ʻumekaumaha i loko o ka hopper a ma o ka ʻāʻī hānai, hāʻule i ka wili wili.A laila, hāʻawi ke kaʻa uila i ka hoʻololi ʻana i ka wili e hoʻoikaika i ka plastic i mua ma o ka pahu wela.

(2) I ka lawe ʻia ʻana o ka acrylic/polycarbonate ma o ka barela, e emi ana ke kahawai a i ʻole ke kaula o ka wili, no laila e hoʻoemi i ka acrylic/polycarbonate.

(3) ʻEkolu a ʻoi aʻe paha nā mea hoʻokele PID Proportional Integral Derivative, e hana ana i nā ʻāpana o ka hoʻonui mālie ʻana i ka mahana, e wela i ka pahu.ʻOi aku ka kiʻekiʻe o ka wela hoʻoheheʻe ʻana o ka acrylic/polycarbonate ma mua o ka wela i hoʻonohonoho ʻia no nā mea hoʻoponopono a ua hana ʻia kēia wela hou ma o ka hui pū ʻana o ka ikaika compressive a me ka shear friction (hea wela).

(4) Ke hiki aku ka hehee plastik i ka hope o ka wiliwili, ua hui pono ia ka hehee plastik a hookui ia ma ka pale pale, i kākoʻo ʻia e ka papa haʻihaʻi, ke kānana ʻana i nā mea haumia a me ka wehe ʻana i nā mea hoʻomanaʻo rotational.

(5) ʻO ka hope e hoʻoheheʻe ʻia ka hoʻoheheʻe ʻia i loko o ka make.Hāʻawi ka die i ka huahana hope i ke ʻano a me ke ʻano i makemake ʻia.Ma hope o ka puka ʻana o ka extruder, huki ʻia ka extrudate a hoʻomaha.
