1)Te tono matua o te cellulose etera kounga rauemi hanga
Ko te ao o ngā rauemi hanga te ao e tino hiahiatia ana e te tini o ngāte etera celluloseHe tino pai ngā āhuatanga o te cellulose ether pērā i te whakamātotoru, te pupuri wai, me te whakaroa, nō reira he whānuitia te whakamahinga hei whakapai ake me te arotau i te moata kua oti te whakaranu (tae atu ki te moata kua whakaranua mākū me te moata kua whakaranua maroke), te hanga kapia PVC, te peita rapa, te putty, te piripiri taera. Mā te mahi a ngā hua rauemi hanga tae atu ki te moata whakamahana wera me ngā rauemi papa ka tutuki i a rātou ngā whakaritenga o te penapena pūngao me te tiaki taiao, ka whakapai ake i te whai huatanga o te hanganga o ngā whare me ngā whakapaipai, ā, ka whakamahia ā-korekore ki te hanga papa rakau me te whakapaipai pakitara o roto me waho o ngā momo kaupapa hanga. Nā te nui o te haumi ki te mara o te hangarau hanga, he maha ngā momo kaupapa hanga, he rerekē te ahunga whakamua o te hanganga, he whānui te whānuitanga o ngā tono o te cellulose ether, he nui te tono mākete, me te marara o ngā kiritaki.
I roto i ngā tauira HPMC rauemi hanga whare taumata waenga me te taumata teitei, ko te HPMC rauemi hanga whare me te pāmahana tiēre o te 75°C te nuinga e whakamahia ana i roto i te moata maroke-ranu me ētahi atu mara. He kaha te ātete ki te pāmahana teitei me te pānga tono pai. Ko tana mahi tono ko te pāmahana tiēre. Kāore e taea te whakakapi e te HPMC rauemi hanga whare i te 60°C, ā, he nui ake ngā whakaritenga a ngā kiritaki taumata teitei mō te pumau kounga o tēnei momo hua. I taua wā anō, he uaua ki te hanga HPMC me te pāmahana tiēre o te 75°C. He nui te tauine haumi o ngā taputapu whakaputa, ā, he teitei te paepae whakauru. He nui ake te utu o te hua i te HPMC rauemi hanga whare me te pāmahana tiēre o te 60°C.
He mea nui te HPMC kounga teitei mō te hanga PVC. Ahakoa he iti noa te nui o te HPMC e tāpirihia ana, ā, he iti noa iho te ōwehenga o ngā utu hanga PVC, he pai te pānga o te tono hua, nō reira he teitei ngā whakaritenga kounga. He iti noa ngā kaihanga o roto me waho o te whare e hanga ana i te HPMC mō te PVC, ā, he nui ake te utu o ngā hua kawemai i tērā o ngā hua o roto.
2)Te Auahatanga Whakawhanaketanga o te Ahumahi Cellulose Ether o te Whare Hanga
①Ko te whanaketanga pumau o te umanga hanga o tōku whenua kei te akiaki tonu i te tono mākete mō te cellulose ether kounga rauemi hanga.
E ai ki ngā raraunga i tukuna e te Tari Tatauranga ā-Motu, i te tau 2021, ka eke te tere o te noho tāone o tōku whenua (te ōwehenga o te taupori tāone i roto i te taupori ā-motu) ki te 64.72%, he pikinga 0.83 ōrau i whakaritea ki te mutunga o te tau 2020, ā, he pikinga i whakaritea ki te tere o te noho tāone o te 49.95% i te tau 2010. 14.77 ōrau, e tohu ana kua uru tōku whenua ki ngā wāhanga waenga me ngā wāhanga whakamutunga o te noho tāone. Nō reira, kua uru hoki te tipu o te tono katoa i roto i te mākete hoko whare ā-rohe ki tētahi wāhanga pumau, ā, kua tino kitea te rerekētanga o te tono i roto i ngā tāone rerekē. Kei te piki haere tonu te tono mō te whare. I te heke mai, me te hekenga o te ōwehenga o te umanga hanga o tōku whenua me te pikinga o te ōwehenga o te umanga ratonga, te pikinga o ngā momo mahi ngāwari pēnei i te auahatanga me te mahi pakihi, me te whanaketanga o ngā tauira tari ngāwari, ka tukuna he whakaritenga hou mō te hokohoko tāone, te wāhi noho me te taurite mahi-whare. Ka nui ake te kanorau o ngā hua hoko whenua e tutuki ai ngā hiahia o te umanga, ā, kua uru te umanga hoko whenua ā-rohe me te umanga hanga ki tētahi wā whakawhiti me te wā panoni.
Ko te tauine haumi o te umanga hanga, te rohe hanga whenua, te rohe kua oti, te rohe whakapaipai whare me ōna huringa, te taumata moni whiwhi a ngā kainoho me ngā tikanga whakapaipai, me ētahi atu, koinei ngā mea matua e pā ana ki te tono a te mākete ā-rohe mō te cellulose ether kounga rauemi hanga. He hononga tata te tukanga o te noho tāone. Mai i te tau 2010 ki te 2021, i mau tonu te ia tipu o te haumi whenua me te uara putanga o te umanga hanga o tōku whenua. I te tau 2021, ko te nui o te haumi whanaketanga whenua o tōku whenua ko te 14.76 trillion yuan, he pikinga tau-ki-te-tau o te 4.35%; ko te uara putanga katoa o te umanga hanga ko te 29.31 trillion yuan, he pikinga 11.04% tau-ki-te-tau.
Mai i te tau 2011 ki te tau 2021, ko te tere tipu ā-tau toharite o te rohe hanga whare i roto i te umanga hanga o tōku whenua he 6.77%, ā, ko te tere tipu ā-tau toharite o te rohe hanga whare kua oti te hanga he 0.91%. I te tau 2021, ko te rohe hanga whare o te umanga hanga o tōku whenua ka 9.754 piriona mita pūrua, me te tere tipu ā-tau o te 5.20%; ko te rohe hanga kua oti ka 1.014 piriona mita pūrua, me te tere tipu ā-tau o te 11.20%. Mā te ia tipu pai o te umanga hanga o roto ka piki ake te whakamahinga o ngā hua rauemi hanga pēnei i te moata kua oti te whakaranu, te hanga kapia PVC, te peita rapa, te putty, me te piripiri taera, ā, nā reira ka akiakihia te hiahia o te mākete mō te cellulose ether kounga rauemi hanga.
②E kaha ana te whenua ki te whakatairanga i ngā rauemi hanga matomato e tohuhia ana e te moata kua oti te whakaranu, ā, kua whānui ake te wāhi whanaketanga mākete o te cellulose ether kounga rauemi hanga.
He matū honohono te moata e whakamahia ana mō te hanga pereki. He mea hanga mai i tētahi ōwehenga o te onepu me ngā rauemi honohono (sima, whakapiri raima, uku, me ētahi atu) me te wai. Ko te tikanga tuku iho mō te whakamahi i te moata ko te whakaranu i te papaanga, engari nā te whanaketanga hangarau o te umanga hanga me te whakapainga o ngā whakaritenga hanga hou, kua piki haere ngā ngoikoretanga o te whakaranu moata i te papaanga, pērā i te kounga koretake, te nui o te para o ngā rauemi, te momo moata kotahi, te iti o te hanganga hou me te whakapoke i te taiao, me ētahi atu.
Ki te whakataurite ki te moata whakaranu i te papaanga, ko te tukanga o te moata kua oti te whakaranu he whakaranu kukū, he kawe kati, he kawe paipa papu, he rehu mīhini ki te pakitara, ā, ko ngā āhuatanga o te tukanga o te whakaranu mākū, e tino whakaiti ana i te whakaputanga puehu, ā, he watea hoki mō te hanga mīhini. Nō reira, he pai ngā painga o te moata kua oti te whakaranu, arā, he pumau te kounga, he nui ngā momo, he taiao hanga hoahoa, he penapena pūngao me te whakaiti i te whakapaunga, ā, he pai ngā painga ōhanga me te taiao. Mai i te tau 2003, kua whakaputa te kawanatanga i ētahi tuhinga kaupapa here nui hei whakatairanga i te hanga me te tono moata kua oti te whakaranu, me te whakapai ake i te paerewa ahumahi moata kua oti te whakaranu.
I tēnei wā, ko te whakamahinga o te moata kua oti te whakaranu hei utu mō te moata whakaranu i te papaanga kua noho hei huarahi nui hei whakaiti i ngā tukunga PM2.5 i roto i te umanga hanga. I ngā rā kei te heke mai, me te korenga o ngā rauemi onepu me te kirikiri, ka piki ake te utu o te whakamahi tika i te onepu i te papaanga, ā, ko te pikinga o ngā utu mahi ka piki haere te utu whakamahi o te moata whakaranu i te papaanga, ā, ka piki tonu te hiahia mō te moata kua oti te whakaranu i roto i te umanga hanga. Ko te nui o te cellulose ether karaehe rauemi hanga i roto i te moata kua oti te whakaranu e tata ana ki te 2/10,000. Mā te tāpiri i te cellulose ether ka āwhina ki te whakamātotoru i te moata kua oti te whakaranu, te pupuri i te wai me te whakapai ake i te mahi hanga. Mā te pikinga ake ka akiaki hoki i te tipu o te hiahia mō te cellulose ether karaehe rauemi hanga.
