Pepa ʻŌpala: He Koho Hoʻomau

He mea koʻikoʻi ka ʻōpala pepa i ka hoʻokele waiwai o ka ʻoihana hana pepa.

• Lōʻihi o ke olonā: 0.7 mm a i 2.5 mm. No ka laʻana, he pōkole nā ​​olonā i loko o ka pepa ʻōpala keʻena, ma kahi o 1 mm, ʻoiai ʻoi aku ka lōʻihi o nā olonā i loko o kekahi pepa ʻōpala wahī.
• Hua PulpʻOkoʻa ia ma muli o ke ʻano, ka maikaʻi, a me ka ʻenehana hana o ka pepa ʻōpala, ma ke ʻano laulā mai 60% a 85%. Hiki i nā pahu corrugated kahiko (OCC) ke loaʻa ka hua pulp ma kahi o 75% a 85% ma hope o ka mālama pono ʻana, ʻoiai ʻo ka pepa ʻōpala keʻena i hui pū ʻia he 60% a 70% ka maʻamau.
• Nā ʻanoHe mea aloha i ke kaiapuni ka hoʻohana ʻana i ka pepa ʻōpala ma ke ʻano he mea maka a he nui ka hua o ka pulp. Hoʻohana nui ʻia ia i ka hana ʻana i ka pepa hana hou a me ka pepa corrugated, e kōkua ana i ka mālama ʻana i nā kumuwaiwai a me ka hoʻēmi ʻana i ka ʻōpala.

Nā Memo Hana Koʻikoʻi

He mea nui e hoʻomaopopo he ʻokoʻa nā kaʻina hana pulping no nā mea maka like ʻole.Pono e kuke ʻia ka lāʻau, ka ʻohe, ka mauʻu maloʻo, a me nā ʻōpala palaoai ka wā o ka pulping.
