ʻO ka pahu hōʻikeʻike keʻokeʻo keʻokeʻo keʻokeʻo pahu pahu cigarette (kēlā me kēia pahu o 10 pahu, kēlā me kēia pahu o 7 ʻeke)

ʻO ka pepa pahu keʻokeʻo he ʻano pepa mānoanoa me ka paʻa a me ke kaumaha nui. No ka mea, ʻaʻole kala ʻia ka ʻili, ua kapa ʻia ka pepa keʻokeʻo. Ua māhele ʻia ka pepa keʻokeʻo o Kina i ʻekolu mau māka A, B, C. ʻAʻole emi ka keʻokeʻo o A ma lalo o 92%; ʻAʻole emi ka papa B ma mua o 87%; ʻAʻole emi ka papa C ma mua o 82%.
ʻO ka mea maka o ka pepa keʻokeʻo he 100% kemika bleached
ʻO ka pahu keʻokeʻo no nā ʻeke cigakeke e koi i ka ʻoʻoleʻa kiʻekiʻe, ke kūpaʻa haki, ka maʻalahi a me ka keʻokeʻo. ʻO nā koi o ka pepa pepa he palahalaha, ʻaʻohe paʻi, kiko, nā niho a me nā puʻupuʻu, warping a me ka deformation o ka hana. E like me ka ʻeke paka me ka pepa keʻokeʻo me ka hoʻohana nui ʻana i ka mīkini paʻi gravure kiʻekiʻe e paʻi, no laila ke kiʻekiʻe nei nā koi o ka pahu pahu keʻokeʻo. Ua ʻike ʻia ke kūpaʻa ʻana i ke ʻano he ikaika tensile a i ʻole ka ikaika tensile, ʻo ia hoʻi ka haʻalulu kiʻekiʻe e hiki ai i ka pepa ke kū i ka wā e haki ai, i hōʻike ʻia ma kN/m. ʻO ka mīkini paʻi gravure kiʻekiʻe e kauo i nā ʻōwili pepa, paʻi kiʻekiʻe-wikiwiki e kū i ke ʻano nui, inā ʻo ke ʻano o ka haki ʻana o ka pepa pinepine, ua hoʻopaʻa ʻia e hoʻohaʻahaʻa pinepine, hoʻemi i ka pono, akā hoʻonui i ka nalowale o ka pepa.
ʻElua ʻano pahu keʻokeʻo no nā ʻeke paka, ʻo FBB (kāleka keʻokeʻo melemele), ʻo SBS (kāleka keʻokeʻo keʻokeʻo keʻokeʻo), ʻo nā ʻeke cigakeke e hoʻohana ana i ka FBB a ʻo SBS he pahu keʻokeʻo i uhi ʻia i hoʻokahi ʻaoʻao, FBB ʻekolu papa. o ka pulp, ka maka a me ka papa lalo e hoʻohana ana i ka pulp lāʻau sulfate, ka papa kumu me ka hoʻohana ʻana i ka pulp lāʻau wili lāʻau kemika. ʻO ka ʻaoʻao mua (ka ʻaoʻao paʻi) ʻo ia ka papa uhi, kahi i hoʻopili ʻia me ʻelua a ʻekolu paha squeegees, ʻoiai ʻo ka ʻaoʻao hope ʻaʻohe papa uhi. No ka mea, ua hana ʻia ka papa waena i ka pulp lāʻau chemically a me mechanically milled, he kiʻekiʻe ka hua o ka pulp i ka lāʻau (85% -90%), a he haʻahaʻa haʻahaʻa ke kumu kūʻai, no laila ua haʻahaʻa ke kumukūʻai o ka pepa pahu FBB.
ʻOi aku ka lōʻihi o ka FBB pulp a me ka liʻiliʻi liʻiliʻi liʻiliʻi a me nā puʻupuʻu fiber, no laila ʻoi aku ka maikaʻi o ka mānoanoa o ka pepa i hoʻopau ʻia, a ʻoi aku ka mānoanoa like o ka FBB ma mua o SBS, ʻo ia hoʻi ka mea maʻamau i ʻekolu papa o ka pulp, ka papa luna. , ka papa kumu a me ka papa lalo e hoʻohana i ka pulp laau sulfate bleached. ʻO ka ʻaoʻao mua (ka ʻaoʻao paʻi) ʻo ia ka papa uhi, i hoʻohana ʻia i ʻelua a ʻekolu mau manawa me ka squeegee like me FBB, ʻoiai ʻo ka ʻaoʻao hope ʻaʻohe papa uhi. No ka mea ua hana ʻia ka papa kumu i ka pulp sulfate bleached, ʻoi aku ka kiʻekiʻe o ka keʻokeʻo, no laila ua kapa ʻia ʻo ia ke kāleka keʻokeʻo keʻokeʻo. I ka manawa like, liʻiliʻi nā pulupulu a ʻoi aku ka paʻa o ka pepa, no laila ʻoi aku ka lahilahi o ka SBS ma mua o ka FBB o ka paona gram like. No ka laʻana, ʻo ka mānoanoa o 230g/m2 FBB o Hongta Renheng he 320μm, ʻoiai ka mānoanoa o 230g/m2 SBS he 295μm.
