ʻO ka ʻike hana ʻeke plastik - paʻi kala

Paʻi pinepine ʻia nā ʻeke ʻeke plastik ma nā kiʻiʻoniʻoni plastik like ʻole, a laila hui pū ʻia me nā ʻāpana pale a me nā ʻāpana hoʻopaʻa wela e hana i nā kiʻi ʻoniʻoni, i ʻoki ʻia a ʻeke ʻia e hana i nā huahana paʻi.Ma waena o lākou,ʻo ka paʻiʻana ka laina mua o ka hana a me ka hana nui loa.No ke ana ʻana i ka māka o kahi huahana paʻi, ʻo ka maikaʻi o ka paʻi ʻana ka mea mua.No laila, ʻo ka hoʻomaopopo ʻana a me ka mālama ʻana i ke kaʻina hana paʻi a me ka maikaʻi ua lilo i kī i ka hana ʻana i ka paʻi paʻi.

ʻEkolu mau kaʻina hana paʻi maʻamau i ka hana ʻana i nā ʻeke plastik:
1. Pa'i 'o Gravure
Hoʻokumu nui ʻia ka paʻi ʻana i ke kiʻiʻoniʻoni plastik ma ke kaʻina paʻi gravure.ʻO ka kiʻiʻoniʻoni plastik i paʻi ʻia me ka gravure ka mea maikaʻi o ka maikaʻi o ka paʻi kiʻekiʻe, ka ʻīnika mānoanoa, ka waihoʻoluʻu ʻālohilohi, ke ʻano māmā a me ka mālamalama, ka papa kiʻi waiwai, ka ʻokoʻa haʻahaʻa, ke kiʻi ʻoniʻoni a me ka manaʻo ikaika ʻekolu.Eia nō naʻe, he mau hemahema ka paʻi gravure ʻaʻole hiki ke nānā ʻole ʻia, e like me ke kaʻina hana paʻi paʻi paʻi paʻa, ke kumu kūʻai nui, ka pōʻai lōʻihi, a me ka pollution nui.
2. Paʻi Flexographic
Hoʻohana mua ka paʻi Flexographic i nā ʻīnika palapala flexographic a maloʻo wikiwiki.He mea maʻalahi nā mea hana, he haʻahaʻa ke kumukūʻai, he māmā ke kaumaha o ka pā, he liʻiliʻi ka paʻi paʻi, liʻiliʻi ka mea pā a me ka poho mechanical, liʻiliʻi ka leo paʻi, a wikiwiki ka wikiwiki.ʻO ka pā flexo he manawa hoʻololi pōkole a me ka hana kiʻekiʻe.He palupalu ka pā flexo, elastic, a he maikaʻi ka hana hoʻoili ʻīnika.He nui nā mea paʻi, a ʻoi aku ka haʻahaʻa o ke kumukūʻai o ka paʻi ʻana i nā pahu liʻiliʻi o nā huahana ma mua o ka paʻi gravure.Eia nō naʻe, ʻoi aku ka nui o nā koi o ka paʻi flexographic i ka ʻīnika a me nā mea paʻi, no laila ʻoi aku ka haʻahaʻa o ka maikaʻi o ka paʻi ʻana i ka hana gravure.
3. Paʻi pale
I ka paʻi ʻana, ma o ka extrusion o ka scraper, ua hoʻoneʻe ʻia ka ʻīnika i ka substrate ma o ka mesh o ka ʻāpana kiʻi e hana i ke kiʻi like me ke kumu.ʻO nā huahana paʻi kiʻi he mau papa inika waiwai, nā waihoʻoluʻu'ālohilohi, nā kala piha, ka mana uhi ikaika, ke koho ākea o nāʻano'īnika, ka hiki ke hoʻololi ikaika, ka haʻahaʻa haʻahaʻa i ka wā o ka paʻiʻana, ka hana maʻalahi, ke kaʻina hana papa maʻalahi, a me ka hoʻolimalima haʻahaʻa o nā lako, no laila he haʻahaʻa ke kumukūʻai. , Nā pono waiwai maikaʻi, nā ʻano mea paʻi like ʻole.
