Hei matū pūmua tūturu, he whānuitia ngā whakamahinga o te cellulose i roto i te hanga. Ko te nuinga o te wā ka ahu mai i ngā pakitara pūtau o ngā tipu, ā, ko tētahi o ngā matū waro tino nui o te ao. Kua whānuitia te whakamahinga o te cellulose i roto i te hanga pepa, kakahu, kirihou, rauemi hanga, rongoā, kai me ētahi atu ahumahi nā tōna hanganga ngota ahurei, tōna kaha ki te pirau i te taiao, me ōna āhuatanga ā-tinana me te matū pai rawa atu.
1. Te umanga hanga pepa
Ko te umanga hanga pepa te mara matua o te whakamahinga o te cellulose. Ka taea te hanga muka tipu hei penupenu i muri i te maimoatanga ā-mīhini, ā-matū rānei. Ko te cellulose te wāhanga matua o tēnei tukanga. I roto i te tukanga hanga pepa, ka taea te whakahaere i te mimiti wai, te maeneene me te kaha kume o te pepa mā te tāpiri i ngā tāpiringa matū me te whakamahi i ngā momo huinga muka. Ko te putanga mai o te pepa hangarua ka whakanui ake i te pumau me te āheinga hangarua o te cellulose, ka nui ake te painga i roto i ngā rauemi e pai ana ki te taiao.
2. Ahumahi kakahu
He whānuitia te whakamahinga o ngā muka cellulose (pērā i te miro) i roto i te hanga papanga hei rauemi mata taketake mō te umanga kakahu. Neke atu i te 90% o ngā muka miro he cellulose, ā, he ngawari, he waiora, he manawa, me ētahi atu āhuatanga pai rawa atu, he pai mō te hanga i ngā momo kākahu. I ngā tau tata nei, ka taea te tukatuka matū i ngā muka cellulose hei hanga i ngā muka cellulose kua whakahoutia pērā i ngā muka viscose me ngā muka modal, ka whakawhānui ake i te whakamahinga o te cellulose i roto i te umanga kakahu. Ehara i te mea he ngawari, he whakamarie hoki ēnei muka, engari he pai hoki ngā āhuatanga patu huakita me te pirau.
3. Ngā kirihou koiora me ngā rauemi pirau-koiora
Ka taea te whakamahi i te cellulose hei hanga kirihou pirau-koiora i roto i te umanga kirihou, koinei tētahi o ngā huarahi rangahau nui hei whakaoti rapanga o te "parahanga mā". Mā te tukatuka i te cellulose hei cellulose acetate, hei cellulose ether rānei, ka taea te whakamahi hei hanga kiriata kirihou e pai ana ki te taiao, taputapu kai, me ētahi atu. He kaha te pumau matū me ngā āhuatanga ā-tinana o ēnei rauemi, ā, he ngāwari ki te pirau i roto i te taiao tūturu, ka whakaiti i te pānga o ngā para kirihou ki te taiao tūturu.
4. Ngā rauemi hanga whare
I roto i te umanga hanga, he whānuitia te whakamahinga o te cellulose hei hanga papa sima muka, papa gypsum kua whakapakaritia ki te muka, me ngā rauemi whakamahana. Mā te whakakotahi i ngā muka cellulose me ētahi atu rauemi ka taea te whakarei ake i tōna ātete pānga, te kaha kume, me te whakapai ake i te whakamahana me te whakamahana oro. Hei tauira, he rauemi whakamahana pai te cellulose. Mā te werohanga i te paura cellulose, i ngā matūriki cellulose rānei ki roto i te pakitara whare, ka taea e ia te whakamahana me te whakaiti i te haruru, ā, ko ōna āhuatanga ā-taiao e ārai ana i ngā pepeke ka nui ake te whakamahinga i roto i te hanga.
5. Ahumahi kai me te rongoā
He mea nui anō hoki ngā whakamahinga o ngā hua cellulose pērā i te carboxymethyl cellulose (CMC) me te methyl cellulose (MC) i roto i ngā ahumahi kai me te rongoā. E whakamahia whānuitia ana te carboxymethyl cellulose hei whakamātotoru, hei whakaū me te whakaemulsifier i roto i te kai, ko te methyl cellulose ia e whakamahia ana hei whakarewa i roto i ngā papa nā te mea he pai tōna piri me tōna hototahi ki te koiora. Hei tāpiri, ka taea hoki te tāpiri i te cellulose ki te kai hei muka kai hei āwhina i te tangata ki te whakapai ake i te hauora o te puku.
6. Ahumahi whakapaipai
He maha ngā wā ka whakamahia te cellulose hei whakamātotoru me te whakaū i roto i ngā mea whakapaipai. Hei tauira, ka taea e te carboxymethyl cellulose me te microcrystalline cellulose te whakanui ake i te matotoru me te pumau o ngā mea whakapaipai, ā, ka karo i te wehewehenga o ngā kai. Hei tāpiri, nā te pirau me te kore paitini o te cellulose, he pai mō te whakamahi i roto i ngā hua horoi, ngā hua tiaki kiri me te hanga-ake.
7. Ngā rauemi e pai ana ki te taiao me ngā rauemi tātari
Nā te hanganga pūwero me te pai o te mimiti o te cellulose, kei te piki haere te whakamahinga i roto i ngā rauemi tātari. Ka whakamahia ngā kiriuhi cellulose me ngā muka nano cellulose ki te tātari hau, te maimoatanga wai me te maimoatanga waipara ā-umanga. Ehara i te mea ka taea e ngā rauemi tātari cellulose te tango noa i ngā matūriki iri, engari ka mimiti hoki i ngā matū kino, me ngā painga o te tino whai hua me te tiaki taiao. Hei tāpiri, mā te rangahau tono o ngā muka nano cellulose ka nui te kaha ki roto i ngā ahumahi tātari me te tiaki taiao ā muri ake nei.
8. Mara pūngao
Kua aro nui hoki te ao pūngao ki te koiora cellulose. Ka taea e te cellulose te whakaputa pūngao hou pērā i te bioethanol me te biodiesel mā te pirau koiora me te whakapūkara. Ki te whakatauritea ki te pūngao petrochemical, he pai te taiao o ngā hua tahunga o te pūngao biomass, ā, e hangai ana ki te ariā o te whanaketanga tauwhiro. Kei te whakapai haere te hangarau whakaputa o te biofuel cellulose, e whakarato ana i ngā huarahi hou mō te pūngao ma a muri ake nei.
9. Te whakamahinga o te nanotechnology
He ahunga whakamua nui ngā muka nano cellulose (CNF) i roto i te rangahau cellulose i ngā tau tata nei. Nā te kaha nui, te iti o te kiato me te pai o te hototahitanga koiora, e whakamahia whānuitia ana i roto i ngā momo rauemi hiato. Mā te tāpiri i ngā muka nano cellulose ka taea te whakapai ake i ngā āhuatanga miihini o ngā rauemi hiato, ā, ki te whakaritea ki ētahi atu rauemi nano, ka taea te whakahou me te pirau i ngā muka nano cellulose, nō reira he nui te kaha ki roto i ngā taputapu hiko, ngā pūoko, ngā whakaurunga hauora me ngā rauemi mahi-teitei.
10. Te hangarau tā me te hangarau waituhi
I roto i te tānga me te hangarau waituhi-ā-ringa, ka whakamahia ngā hua cellulose hei whakapai ake i te rere me te mimiti o ngā waituhi, kia ōrite ake ai te pānga tā. I roto i ngā waituhi tā waituhi-ā-ringa, ka taea e te cellulose te whakakī me te mārama ake i ngā tae. Hei tāpiri, mā te mārama me te kaha o te cellulose ka whakapai ake i te kounga o te pepa tā me te whakaiti i te horapa o te waituhi, ā, ka pai ake te kounga o ngā hua tā.
Hei rauemi pūmua taiao ka taea te whakahou me te pirau, kua noho te cellulose hei tētahi o ngā rauemi nui i roto i te hanga hou. Ko tōna whakamahinga whānui i roto i ngā mara rerekē e whakaatu ana i tōna kanorau me te tiaki taiao, ā, e whakatairanga ana i te huringa matomato o te maha o ngā ahumahi. I te heke mai, me te whanaketanga tonu o te pūtaiao me te hangarau me te putanga whakamua o te nanotechnology cellulose, ka nui ake te kanorau o te whakamahinga o te cellulose.
