1. He aha kaPepa Pohaku?
Hana ʻia ka pepa pōhaku i nā kumu waiwai limestone me nā waihona nui a me ka hāʻawi ākea ʻana ma ke ʻano he kumu waiwai nui (ʻo ka calcium carbonate content he 70-80%) a me ka polymer ma ke ʻano he mea kōkua (ʻo ka ʻiʻo he 20-30%). Ma ka hoʻohana ʻana i ke kumu o ka polymer interface chemistry a me nā ʻano o ka hoʻololi polymer, hana ʻia ka pepa pōhaku e ka polymer extrusion a me ka ʻenehana puhi ʻana ma hope o ka hana kūikawā. ʻO nā huahana pepa pōhaku ka hana kākau a me ka hopena paʻi like me ka pepa fiber mea kanu. I ka manawa like, loaʻa iā ia nā waiwai koʻikoʻi o ka pahu plastik.
2. Nā mea nui o ka pepa pōhaku?
ʻO nā waiwai pepa pōhaku e pili ana i ka palekana, ke kino, a me nā hiʻohiʻona ʻē aʻe, a ʻo nā hiʻohiʻona nui he wai wai, pale i ka noe, pale i ka aila, nā pepeke, a me nā mea ʻē aʻe, a ma nā waiwai kino ke kūʻē i ka haehae ʻana, ʻoi aku ka maikaʻi o ka pale ʻana ma mua o ka pepa pulp lāʻau.
ʻAʻole e kālai ʻia ka paʻi pepa pōhaku me ka wehewehe kiʻekiʻe, a hiki i ka 2880DPI pololei, ʻaʻole uhi ʻia ka ʻili me ke kiʻiʻoniʻoni, ʻaʻohe hana kemika me ka ʻīnika, e pale aku ai i ke kala kala a me ka decolorization.
3. No ke aha mākou e koho ai i ka pepa pōhaku?
a. Pono waiwai maka. Pepa kuʻuna e hoʻopau i ka nui o ka lāʻau, a me ka pepa pōhaku ka loa nui o ka mineral waiwai i loko o ka honua crust calcium carbonate e like me ke kumu maka mea, ma kahi o 80%, polymer mea - he petrochemical hana o polyethylene (PE) ma kahi o 20%. Inā e hoʻolālā i ka hoʻopuka makahiki o 5400kt pepa pōhaku, 8.64 miliona m3 lāʻau hiki ke mālama ʻia i kēlā me kēia makahiki, e like me ka hōʻemi ʻana i ka hoʻopau ʻana i ka ululāʻau o 1010 kilomika square. Wahi a ke kaʻina hana maʻamau o ka hoʻohana ʻana i ka wai o 200t no ka ton o ka pepa, hiki i ka puka makahiki o 5.4 miliona tons o ka papahana pepa pōhaku ke hoʻopakele i 1.08 miliona mau wai wai i kēlā me kēia makahiki.
b. Nā pono kaiapuni. ʻAʻole pono ka wai i ke kaʻina hana a pau o ka hana pepa pōhaku, ke hoʻohālikelike ʻia me ka hana pepa maʻamau, holoi ʻia ka kuke, ka holoi ʻana, ka bleaching a me nā ʻanuʻu haumia ʻē aʻe. I ka manawa like, hoʻouna ʻia ka pepa pōhaku i hana ʻia i ka incinerator no ka hoʻopau ʻana, ʻaʻole ia e hoʻopuka i ka uahi ʻeleʻele, a hiki ke hoʻihoʻi ʻia ke koena o ka pauka mineral inorganic i ka honua a me ke ʻano.
Ho'ōla nui ka hana pepa pōhaku i nā kumu ululāʻau a me nā kumu wai, a ʻo ka hoʻohana ʻana i ka ikehu he 2/3 wale nō o ke kaʻina hana pepa maʻamau.
