ʻO ka pulp bamboo kahi ʻano pulp i hana ʻia mai nā mea ʻohe e like me ka moso bamboo, nanzhu, a me cizhu. Hana ʻia ia me ka hoʻohana ʻana i nā ʻano like me ka sulfate a me ka soda caustic. Hoʻohana kekahi i ka lime no ka ʻohi ʻana i ka ʻohe palupalu i semi clinker ma hope o ka ʻōmaʻomaʻo. Aia ka morphology a me ka lōʻihi ma waena o ka lāʻau a me ka mauʻu. Maʻalahi ka hoʻopili ʻana i ke kāpili, ʻo ka pulp bamboo he pulp ka lōʻihi o ka fiber me ka maikaʻi a palupalu. He kiʻekiʻe ka mānoanoa a me ka waimaka o ka pulp, akā haʻahaʻa ka ikaika o ka haki a me ka ikaika tensile. Loaʻa i ka ikaika mechanical kiʻekiʻe.
I Kekemapa 2021, ʻumi mau keʻena me ka State Forestry and Grassland Administration a me ka National Development and Reform Commission i hoʻopuka pū i ka "Opinions on Accelerating the Innovative Development of the Bamboo Industry". Ua hoʻokumu pū nā ʻāpana like ʻole i nā kulekele kākoʻo e hoʻolōʻihi i ka noiʻi a me ka hoʻomohala ʻana i nā ʻenehana hou a me nā kaʻina hana no ka mālama ʻana i ke kaiaola a me ke kaiapuni i ka hana ʻana i ka pepa pulp bamboo, e hāʻawi ana i ke kākoʻo kulekele ikaika no ka hoʻolaha ʻana i ka hoʻomohala kiʻekiʻe o ka ʻoihana ʻohe, me ka ʻoihana pulp pulp papermaking. .
Mai ka hiʻohiʻona o ke kaulahao ʻoihana, ʻo nā mea waiwai nui o ka upstream no ka pulp bamboo he bamboo e like me moso, nanzhu, a me cizhu; ʻO ka lalo o ka pulp bamboo e pili ana i nā ʻoihana hana pepa like ʻole, a ʻo ka pepa i hana ʻia he paʻa a he "leo". Hoʻohana ʻia ka pepa bleached no ka hana ʻana i ka pepa paʻi offset, pepa paʻi, a me nā pepa moʻomeheu kiʻekiʻe ʻē aʻe, ʻoiai hiki ke hoʻohana ʻia ka pepa bleached no ka hana ʻana i ka pepa paʻi, a pēlā aku. me ka ʻāpana ulu lāʻau ʻohe i ʻoi aku ma mua o 1/4 o ka nui o ka ululāʻau ʻohe honua a me ka hana ʻohe no ka 1/3 o ka nui o ka hana honua. I ka makahiki 2021, he 3.256 biliona ka hana ʻohe o Kina, he piʻi o 0.4% ma mua o ka makahiki i hala.
E like me ka ʻāina me ka nui o ka hana pulp ʻohe ma ka honua, ua loaʻa iā Kina he 12 mau laina hana pulp kemika hou me ka mana hana makahiki o 100000 tons, me ka nui o ka mana hana o 2.2 miliona tons, me 600000 tons of bamboo soluble pulp production. hiki. ʻO ka mana hou o ke kauoha hoʻopaʻa ʻana i ka plastic e kuhikuhi ana i ke ʻano o ka hoʻopaʻa ʻana i ka plastic a me ke koho ʻana i nā huahana ʻē aʻe, e lawe mai ana i nā manawa hou no nā ʻoihana hana pepa pulp bamboo. I ka makahiki 2022, he 2.46 miliona tons ka hana ʻana o ka pulp ʻohe o Kina, he 1.7% ka piʻi ʻana o kēlā me kēia makahiki.
ʻO Sichuan Petrochemical Yashi Paper Industry Co., Ltd. he lālā ia o China Petrochemical Group. ʻO ia ka ʻoihana hana nui loa ma ka ʻoihana pepa maoli pulp bamboo ma Kina, me ka piha piha o nā kikoʻī a me nā ʻano. ʻO ia hoʻi ka ʻoihana ʻelele maikaʻi loa o 100% ʻohe pepa maoli no ka hoʻohana ʻana i kēlā me kēia lā ma Kina. He ʻoihana ʻenehana kiʻekiʻe o ka ʻāina i ʻike i ka noiʻi a me ka hoʻomohala ʻana, ka hana ʻana, a me ke kūʻai ʻana aku i ka pepa hale kiʻekiʻe a ʻo kekahi o nā ʻoihana pepa hale ʻumi ma ka ʻāina ʻo Sichuan. ʻO kāna huahana i hoʻopau ʻia, ka nui o ke kūʻai ʻana, a me ka māhele mākeke, ua helu mua ʻia ma ka ʻoihana hana pepa hale ma ka ʻāina ʻo Sichuan no ʻeono mau makahiki, a ua kau mua ʻo ia i ka ʻoihana pepa maoli pulp bamboo no nā makahiki ʻehā.
