Ko te cellulose mō te hanga he tāpiringa e whakamahia ana i roto i te hangahanga. Ko te cellulose mō te hangahanga ka whakamahia nuitia i roto i te moata paura maroke. He iti noa te tāpiri o te cellulose ether, engari ka taea e ia te whakapai ake i te mahi a te moata mākū me te pā ki te hanganga o te moata. Me aro nui ki te mahi i roto i te whakamahinga. Nō reira, he aha ngā āhuatanga ā-tinana o te cellulose mō te hangahanga, ā, he aha te tukanga hanga o te cellulose mō te hangahanga? Mena kāore koe i te mōhio nui ki ngā āhuatanga me te tukanga hanga o te cellulose mō te hangahanga, me titiro tahi tātou.
He aha ngā āhuatanga ā-tinana o te cellulose mō te hanga:
1. Āhua: paura mā, paura mā-parauri rānei.
2. Rahi o te matūriki; ko te tere paahi o te 100 mata he nui ake i te 98.5%; ko te tere paahi o te 80 mata he nui ake i te 100%.
3. Te pāmahana whakapūngao: 280-300°C
4. Te mātotoru āhua: 0.25-0.70/cm3 (tata ki te 0.5g/cm3), te taumaha motuhake 1.26-1.31.
5. Te pāmahana whakarerekētanga tae: 190-200°C
6. Te kukū o te mata: ko te 2% o te wairewa he 42-56dyn/cm.
7. Ka wairewa ki te wai me ētahi whakarewa, pērā i te ōwehenga tika o te etanoru/wai, te propanol/wai, te trichloroethane, me ētahi atu. He kaha te mahi mata o ngā otinga wai. He mārama teitei, he pumau te mahi, he rerekē te pāmahana tiēre o ngā whakatakotoranga hua, ka rerekē te wairewatanga me te matotoru, ko te iti o te matotoru, ko te nui ake o te wairewatanga, he rerekē te mahi a ngā whakatakotoranga rerekē o te HPMC, ā, kāore te uara pH e pāngia e te wairewatanga o te HPMC i roto i te wai.
8. I te whakahekenga o te ihirangi methoxyl, ka piki ake te ira tio, ka heke te wairewatanga wai o te HPMC, ā, ka heke hoki te ngohe o te mata.
9. Kei te HPMC anō hoki ngā āhuatanga o te kaha ki te whakamātotoru, te ātete ki te tote, te paura pungarehu iti, te pumau o te PH, te pupuri wai, te pumau o ngā āhuatanga, te āhuatanga hanga kiriata pai rawa atu, me te whānuitanga o te ātete ki ngā whākōkī, te marara me te piripono.
He aha te tukanga hanga o te cellulose mō te hanga:
1. Ngā whakaritenga taumata-turanga: Mena kāore e taea e te piri o te pakitara taumata-turanga te whakatutuki i ngā whakaritenga, me horoi pai te mata o waho o te pakitara taumata-turanga, ā, me pania he kaihoko atanga hei whakanui ake i te kaha pupuri wai o te pakitara, kia pai ake ai te kaha here i waenga i te pakitara me te papa polystyrene.
2. Rārangi whakahaere purei: whakapūpū ake ngā rārangi whakahaere whakapae me te poutū o ngā tatau me ngā matapihi o waho, ngā hononga whānui, ngā hononga whakapaipai, me ētahi atu ki te pakitara.
3. Whakairihia te rārangi tohutoro: Whakairihia ngā waea maitai tohutoro poutū ki ngā kokonga nui (ngā kokonga o waho, ngā kokonga o roto) o ngā pakitara o waho o te whare me ētahi atu wāhi e tika ana, ā, whakairihia ngā rārangi whakapae ki ngā tūranga tika i ia papa hei whakahaere i te poutū me te papatahi o te papa polystyrene.
4. Te whakarite i te moata piri pūmua: He moata piri pūmua tēnei rauemi, me whakamahi kia rite ki ngā whakaritenga o tēnei hua, me te kore e tāpiri i ētahi atu rauemi, pērā i te sima, te onepu me ētahi atu pūmua.
5. Whakapirihia te kakahu matawhatu kua hurihia: Me pania ngā wāhi katoa e kitea ana i te taha o te papa polystyrene kua whakapirihia (pērā i ngā hononga whānui, ngā hononga taunga whare, ngā hononga pāmahana me ētahi atu tuitui i ngā taha e rua, ngā tatau me ngā matapihi) ki te kakahu matawhatu.
6. Papa polystyrene piri: Kia mahara ko te tapahi he poutū ki te mata o te papa. Me tutuki te rerekētanga rahi i ngā whakaritenga o ngā ture, ā, kaua ngā hononga o te papa polystyrene e waiho ki ngā kokonga e whā o te tatau me te matapihi.
7. Te whakamau i ngā punga: neke atu i te 2 ngā punga mō ia mita pūrua (kua piki ake ki te neke atu i te 4 mō ngā whare teitei).
8. Whakaritea te moata parai: Whakaritea te moata parai kia rite ki te ōwehenga i whakaratohia e te kaihanga, kia tika ai te ine, kia tika ai te whakaoho ā-ringa, kia ōrite ai te whakaranu.
I roto i ngā momo cellulose e whakamahia ana i roto i te hanganga, ko te cellulose ether e whakamahia ana e te hydroxypropyl methylcellulose i roto i te moata paura maroke ko te hydroxypropyl methylcellulose ether te nuinga. Ko te mahi nui a te Hydroxypropyl methylcellulose ko te pupuri wai, te whakamātotoru me te whakapai ake i te mahi hanganga i roto i te moata paura maroke.
