He momo rauemi i ahu mai i te pūmua tūturu te cellulose ether, ā, he āhuatanga tōna o te emulsification me te suspension. I roto i ngā momo maha, ko te HPMC te mea he nui rawa te putanga me te mea e whakamahia whānuitia ana, ā, kei te tere piki haere tōna putanga.
I ngā tau tata nei, nā te tipu o te ōhanga o te motu, kua piki ake te hanga o te cellulose ether i tōku whenua i ia tau. I taua wā anō, me te whanaketanga o te pūtaiao me te hangarau o te motu, ko ngā cellulose ether kounga teitei i hiahiatia he nui o ngā kawemai i te tīmatanga kua āta haeretia inaianei ki te rohe, ā, kei te piki haere tonu te rahinga kaweake o ngā cellulose ether o te motu. E whakaatu ana ngā raraunga mai i Hānuere ki Noema 2020, kua eke te kaweake o te cellulose ether a Haina ki te 64,806 tana, he pikinga tau-ki-te-tau o te 14.2%, he teitei ake i te rahinga kaweake mō te tau 2019 katoa.
Ka pāngia te etera cellulose e ngā utu miro o te awa：
Ko ngā rauemi mata matua o te cellulose ether ko ngā hua ahuwhenua me ngā hua ngahere tae atu ki te miro kua whakapaia, me ngā hua matū tae atu ki te propylene oxide. Ko ngā miro kua whakapaia ko ngā miro kua whakakīia. He nui te hanga miro i tōku whenua, ā, ko ngā wāhi hanga miro kua kohia ki Shandong, Xinjiang, Hebei, Jiangsu me ētahi atu wāhi. He tino nui, he nui hoki ngā miro kua whakakīia.
He nui te wāhanga o te miro i roto i te hanganga ōhanga ahuwhenua, ā, he maha ngā āhuatanga e pāngia ana e tōna utu, pērā i ngā āhuatanga taiao me te tono me te tuku o te ao. Waihoki, ko ngā hua matū pērā i te propylene oxide me te methyl chloride, ka pāngia hoki e ngā utu hinu mata o te ao. Nā te mea he nui te wāhanga o ngā rauemi mata i roto i te hanganga utu o te cellulose ether, ka pā tika ngā piki me ngā heke o ngā utu o ngā rauemi mata ki te utu hoko o te cellulose ether.
Hei whakautu i te pēhanga utu, ka tukuna e ngā kaihanga cellulose ether te pēhanga ki ngā ahumahi o raro, engari ka pāngia te pānga whakawhiti e te uaua o ngā hua hangarau, te kanorau o ngā hua me te uara tāpiri utu hua. I te nuinga o te wā, he nui ake ngā painga o ngā umanga he nui ngā arai hangarau, he nui ngā kāwai hua, he nui hoki te uara tāpiri, ā, ka mau tonu te taumata pumau o te hua katoa o ngā umanga; ki te kore, me aro atu ngā umanga ki te pēhanga utu nui ake. Hei tāpiri, ki te kore e pumau te taiao o waho, ā, he nui te whānuitanga o ngā rerekētanga hua, ka pai ake ngā kamupene rauemi mata o runga ki te whiriwhiri i ngā kaihoko o raro me te tauine whakaputa nui me te kaha whānui kaha hei whakarite i ngā painga ōhanga i te wā tika me te whakaiti i ngā mōrearea. Nō reira, ka whakawhāitihia e tēnei te whanaketanga o ngā umanga cellulose ether iti ki tētahi taumata.
Hanganga Mākete o raro：
I te whanaketanga tonu o te pūtaiao me te hangarau, ka tipu haere te mākete tono o raro. I taua wā anō, e matapaetia ana ka whānui haere tonu te whānuitanga o ngā tono o raro, ā, ka mau tonu te tipu pumau o te tono o raro. I roto i te hanganga mākete o raro o te cellulose ether, ko ngā rauemi hanga, te tūhuratanga hinu, te kai me ētahi atu mara he tūranga nui. I roto i ēnei, ko te rāngai rauemi hanga te mākete kaihoko nui rawa atu, neke atu i te 30%.
Ko te umanga hanga te mara kaihoko nui rawa atu o ngā hua HPMC：
I roto i te umanga hanga, he mea nui te mahi a ngā hua HPMC ki te here me te pupuri wai. Whai muri i te whakaranu i te iti o te HPMC ki te moata sima, ka taea te whakanui ake i te matotoru, te kaha kume me te kaha kutikuti o te moata sima, te moata, te here, me ētahi atu, ā, ka whakapai ake i te mahi a ngā rauemi hanga, ka whakapai ake i te kounga hanga me te whai huatanga o te hanga miihini. Hei tāpiri, he mea nui hoki te HPMC hei whakaroa i te hanga me te kawe i te raima arumoni, ka taea te raka i te wai me te whakarei ake i te rheology o te raima. I tēnei wā, ko te HPMC te hua cellulose ether matua e whakamahia ana i roto i ngā rauemi hiri hanga.
Ko te umanga hanga whare tētahi pou matua o te ōhanga ā-motu o tōku whenua. E whakaatu ana ngā raraunga kua piki ake te whānuitanga o ngā whare hanga whare mai i te 7.08 piriona mita pūrua i te tau 2010 ki te 14.42 piriona mita pūrua i te tau 2019, ā, kua tino whakaohooho tēnei i te tipu o te mākete cellulose ether.
Kua hoki mai te hua whānui o te umanga hoko whenua, ā, kua piki ake te rohe hanga me te hoko i ia tau. E whakaatu ana ngā raraunga a te iwi whānui i te tau 2020, kua heke te hekenga o te rohe hanga hou o ngā whare noho arumoni i ia tau, ā, ko te hekenga i ia tau ko te 1.87%. I te tau 2021, e matapaetia ana ka haere tonu te ia o te whakaoranga. Mai i Hānuere ki Pēpuere o tēnei tau, kua hoki mai te tere tipu o te rohe hoko o ngā whare arumoni me ngā whare noho ki te 104.9%, he pikinga nui tēnei.
Te Keri Hinu:
Ko te mākete ratonga hangarau keri e tino pāngia ana e ngā haumitanga tūhura me te whakawhanaketanga o te ao, me te tata ki te 40% o te putea tūhura o te ao e whakatapua ana ki ngā ratonga hangarau keri.
I te wā e keri ana i te hinu, he mea nui te mahi a te wai keri ki te kawe me te whakatarewa i ngā tapahi, te whakapakari i ngā pakitara poka me te whakataurite i te pēhanga hanganga, te whakamatao me te whakahinuhinu i ngā mata keri, me te tuku i te kaha waiora. Nō reira, i roto i te mahi keri hinu, he mea tino nui kia mau tonu te haumākū, te matotoru, te rere me ētahi atu tohu o te wai keri. Ka taea e te cellulose polyanionic, PAC, te whakamātotoru, te whakahinuhinu i te mata keri, me te tuku i te kaha waiora. Nā te uaua o ngā āhuatanga whenua i roto i te wāhi rokiroki hinu me te uaua o te keri, he nui te hiahia mō te PAC.
Te umanga taputapu rongoā:
E whakamahia whānuitia ana ngā etera cellulose kore-ionic i roto i te umanga rongoā hei tāpiri rongoā pēnei i ngā mea whakamātotoru, ngā mea whakamarara, ngā mea whakaemulsifier me ngā mea hanga kiriata. E whakamahia ana mō te paninga kiriata me te piri o ngā papa rongoā, ā, ka taea hoki te whakamahi mō ngā whakatārewatanga, ngā whakaritenga kanohi, ngā papa mānu, me ētahi atu. Nā te mea he kaha ake ngā whakaritenga mō te cellulose etera kounga rongoā mō te parakore me te matotoru o te hua, he uaua te tukanga hanga, ā, he maha atu ngā tukanga horoi. Ki te whakatauritea ki ētahi atu momo hua cellulose etera, he iti ake te tere kohikohi me te utu whakaputa, engari he teitei ake te uara tāpiri o te hua. Ko ngā tāpiri rongoā e whakamahia ana i roto i ngā hua whakarite pēnei i ngā whakaritenga matū, ngā rongoā pateni Hainamana me ngā hua matū koiora.
Nā te tīmatanga tōmuri o te umanga tāpiri rongoā o tōku whenua, he iti te taumata whanaketanga whānui o nāianei, ā, me whakapai ake anō te tikanga ahumahi. I roto i te uara putanga o ngā whakaritenga rongoā ā-rohe, ko te uara putanga o ngā takai rongoā ā-rohe he iti noa te ōwehenga o te 2% ki te 3%, he iti iho i te ōwehenga o ngā tāpiri rongoā o tāwāhi, arā, tata ki te 15%. Ka kitea he nui tonu te wāhi mō ngā tāpiri rongoā ā-rohe hei whanaketanga., E matapaetia ana ka whakaoho pai i te tipu o te mākete cellulose ether e pā ana.
Mai i te tirohanga o te hanga cellulose ether ā-rohe, ko Shandong Head te kamupene kei a ia te kaha whakaputa nui rawa atu, e 12.5% o te kaha whakaputa katoa, ā, whai muri ko Shandong RUITAI, Shandong YITENG, North TIANPU Chemical me ētahi atu umanga. I te nuinga o te wā, he kaha te whakataetae i roto i te umanga, ā, e matapaetia ana ka piki ake te kukū o te kamupene.
