Hoʻokumu ʻia ka fiber Viscose i ka cellulose maoli (pulp hectometer) maka, e wili hou ana ma hope o ka hopena o ka ester acid melemele i loko o ka fiber a me ka fiber cellulose regenerated.I ka hana ʻana o ka viscose fiber solidification kaʻina, dilute sodium hydroxide a me ka sulfuric acid i loko o ka ʻauʻau ʻauʻau solidification e hana i ka glauberite (sodium silicate pauka).Mai ka hiʻohiʻona o ka hoʻihoʻi hou ʻana i ka wai, ʻoi aku ka maikaʻi o ka sodium sulfate i hoʻihoʻi ʻia mai ka wai ʻōpala i ke kaʻina hana viscose silk.Hōʻike ka hōʻike nānā maikaʻi i nā mea maikaʻi o ka viscose fiber by-product sodium sulfate huahana: keʻokeʻo maikaʻi, ka ʻike huahana kiʻekiʻe, haʻahaʻa haʻahaʻa chloride ion, haʻahaʻa kumu kūʻai a me ke kumu kūʻai maʻalahi;ʻO ka hemahema o ka huahana: ʻo ka nui o ka ʻāpana maikaʻi, maʻalahi i ka caking, ka waiwai PH acidic.ʻO ka pauka viscose fiber by-product powder he kūpono ia no ke aniani, ka pepa a me nā ʻoihana ʻē aʻe.
He mea hana nui ʻo Kina i ka fiber chemical a he mea hana ikaika i ka hoʻomohala ʻana.I kēia mau makahiki i hala iho nei, ʻo ka ʻoihana cellulose fiber recycled i ko mākou ʻāina ka nui o ka fiber staple, me ka mana hana o kahi o 5 miliona tons.Wahi a nā helu helu o Yuanming powder industry information public platform, ʻo ka hana ʻana o ka sodium byproduct sulfate i loko o ka ʻoihana fiber kemika e pili ana i ka hapalua o ka nui o ka hana ʻana o ka sodium byproduct sulfate ma ka ʻāina, ʻo ia ka mea kiʻekiʻe loa i nā ʻano o ka sodium byproduct sulfate ʻoihana. i kēia manawa.
ʻO ka fiber staple viscose no ka fiber regeneration o ka cellulose maoli, a ʻo ka pulupulu a me ka polyester staple fiber no nā mea wili nui ʻekolu.Hana ʻia ia me ka cellulose maoli (pulp) ma ke ʻano he kumu kumu, ma o ka alkalination, ka ʻelemakule, ka sulfonation a me nā kaʻina hana ʻē aʻe i loko o ka cellulose sulfonate hiki ke hoʻoheheʻe ʻia, a laila hoʻoheheʻe ʻia i ka lye dilute e hana i ka viscose, ma ka milo pulu a hana ʻia.
Wahi a nā helu helu, i ka makahiki 2021, ʻo 4.031 miliona mau tons ka hua viscose fiber o Kina, he piʻi o 1.93% i hoʻohālikelike ʻia me 2020. E like me ka lōʻihi o ka fiber, hiki ke hoʻokaʻawale ʻia ka viscose fiber i viscose staple fiber a me viscose filament.I ka makahiki 2021, hiki i ka 3.87 miliona tons ka puka o ka viscose staple fiber, me ka piʻi ʻana o ka makahiki he 2.12%;ʻO ka hana filament viscose he 161,000 tons, ma lalo o 2.42% i kēlā me kēia makahiki.
