Te Waikawa Waikawa Metilururo (HPMC)He pūmua wairewa-wai te HPMC e whakamahia whānuitia ana i roto i ngā ahumahi rongoā, kai, whakapaipai, me te hanga. He mea nui te makuku o te HPMC ki tana tukatuka me te pumau. Ka pā ki ngā āhuatanga rheological, te wairewa, me te roa o te oranga o te rauemi. He mea nui te mārama ki te makuku mō tōna hanganga, te rokiroki, me te whakamahinga whakamutunga.
Te Ihirangi Makuku o te HPMC
Ko te nui o te makuku o AnxinCel®HPMC ka whakatauhia i runga i ngā āhuatanga o te tukanga me te taumata motuhake o te polymer e whakamahia ana. Ka rerekē pea te nui o te makuku i runga i te rauemi mata, ngā āhuatanga rokiroki, me te tukanga whakamaroke. I te nuinga o te wā ka whakaatuhia hei ōrau o te taumaha o te tauira i mua me muri i te whakamaroke. Mō ngā tono ahumahi, he mea nui te nui o te makuku, nā te mea ka taea e te makuku nui te arahi ki te pirau, te piri, te whakaiti rānei i te mahi a te HPMC.
Ka taea e te nui o te makuku o te HPMC te awhe mai i te 5% ki te 12%, engari ko te awhe noa kei waenganui i te 7% me te 10%. Ka taea te whakatau i te nui o te makuku mā te whakamaroke i tētahi tauira i tētahi pāmahana motuhake (hei tauira, 105°C) kia eke rā anō ki tētahi taumaha pumau. Ko te rerekētanga o te taumaha i mua atu me muri i te whakamaroketanga e tohu ana i te nui o te makuku.
Ngā Take e Pā Ana ki te Ihirangi Makuku i roto i te HPMC
He maha ngā āhuatanga ka pā ki te nui o te makuku o te HPMC:
Te haumākū me ngā tikanga rokiroki:
Ka taea e te nui o te haumākū, te kore rānei o ngā tikanga rokiroki tika te whakanui ake i te nui o te makuku o te HPMC.
He higroscopic te HPMC, arā, ka mimiti i te makuku mai i te hau e karapoti ana.
Mā te tākai me te hiri o te hua ka whakaiti i te mimiti o te makuku.
Ngā Tikanga Tukatuka:
Ka pā te pāmahana me te roa o te wā whakamaroke ki te nui o te makuku whakamutunga.
Ka taea e te maroke tere te hua ake he makuku toenga, engari ka taea e te maroke puhoi te pupuri i te makuku nui ake.
HPMC Tau:
Tērā pea he rerekē te nui o te makuku i roto i ngā momo HPMC rerekē (hei tauira, te matotoru iti, te matotoru waenga, te matotoru teitei rānei) nā te rerekētanga o te hanganga ngota me te tukatuka.
Ngā Whakatakotoranga a te Kaiwhakarato:
Ka taea e ngā kaiwhakarato te whakarato ki te HPMC me te nui o te makuku kua tohua e hangai ana ki ngā paerewa ahumahi.
Te Ihirangi Makuku Noa o te HPMC mā te Taumata
Ka rerekē te nui o te makuku o te HPMC i runga i te momo me te whakamahinga e whakaarohia ana. Anei tētahi ripanga e whakaatu ana i ngā taumata makuku noa mō ngā momo rerekē o te HPMC.
| HPMC Grade | Te matotoru (cP) | Te Ihirangi Makuku (%) | Ngā tono |
| HPMC Mataotao Iti | 5 – 50 | 7 – 10 | Ngā rongoā (papa, kāpū), ngā mea whakapaipai |
| HPMC Matotoru Waenga | 100 – 400 | 8 – 10 | Ngā rongoā (tukunga whakahaere), kai, piripiri |
| HPMC Mataotao Teitei | 500 – 2000 | 8 – 12 | Hanganga (he mea hanga ki te sima), kai (he mea whakamātotoru) |
| HPMC Rongoā | 100 – 4000 | 7 – 9 | Papa, paninga kāpūru, whakatakotoranga tiēre |
| HPMC Kai-Kōeke | 50 – 500 | 7 – 10 | Te whakamātotorutanga o te kai, te whakaemulsification, ngā paninga |
| HPMC Taumata Hanganga | 400 – 10000 | 8 – 12 | Mota, piripiri, pāreti, ranunga maroke |
Te Whakamātautau me te Whakatau i te Ihirangi Makuku
He maha ngā tikanga paerewa hei whakatau i te nui o te makuku o te HPMC. Ko ngā tikanga e rua e tino kitea ana ko:
Tikanga Ine Taumaha (Ngaronga i te Whakamaroke, LOD):
Koinei te tikanga e whakamahia whānuitia ana mō te whakatau i te nui o te makuku. Ka whakatakotoria te taumaha HPMC e mōhiotia ana ki roto i te oumu whakamaroke kua whakatakotoria ki te 105°C. I muri i tētahi wā kua tohua (te tikanga 2–4 hāora), ka paunatia anō te tauira. Mā te rerekētanga o te taumaha ka puta te nui o te makuku, e whakaatuhia ana hei ōrau o te taumaha tauira tuatahi.
Te Whakatauritenga a Karl Fischer:
He tika ake tēnei tikanga i te LOD, ā, he tauhohenga matū kei roto e ine ana i te nui o te wai. Ko te tikanga o tēnei tikanga he mea whakamahi ina hiahiatia he whakatau tika i te makuku.
Te Pānga o te Ihirangi Makuku ki ngā Āhuatanga HPMC
Ka pāngia te mahi a te makuku o AnxinCel®HPMC i roto i ngā momo whakamahinga:
Te matotoru:Ka pā te nui o te makuku ki te matotoru o ngā otinga HPMC. Ka taea e te nui o te makuku te whakanui ake i te matotoru o ētahi hanganga, engari ka taea e te iti o te makuku te whakaiti i te matotoru.
Te wairewatanga:Ka taea e te makuku nui te arahi ki te whakaemi, te whakaiti rānei i te wairewatanga o te HPMC i roto i te wai, ka kore ai e whai hua mō ētahi tono, pērā i ngā whakatakotoranga tukunga whakahaere i roto i te umanga rongoā.
Te pumau:He pumau te HPMC i ngā āhuatanga maroke, engari ka taea e te nui o te makuku te hua ake te tipu o ngā moroiti, te pirau matū rānei. Nā konei, ka rongoatia te HPMC i roto i ngā ipu hiri i roto i ngā taiao iti te makuku.
Te Ihirangi Makuku me te Tākai o te HPMC
Nā te āhua waiora o te HPMC, he mea nui te takai tika hei ārai i te mimiti o te makuku mai i te hau. Ko te tikanga, ka takaihia te HPMC ki roto i ngā putea, i ngā ipu rānei e ārai ana i te makuku, he mea hanga ki ngā rauemi pēnei i te polyethylene, i ngā paparanga maha rānei hei tiaki i a ia mai i te makuku. Mā te takai ka noho tonu te nui o te makuku ki roto i te awhe e hiahiatia ana i te wā e rongoatia ana, e kawehia ana hoki.
Te Whakahaere i te Ihirangi Makuku i roto i te Hanganga
I te wā e hangaia ana te HPMC, he mea nui kia aroturukitia te nui o te makuku hei pupuri i te kounga o te hua. Ka taea tēnei mā te:
Ngā Tikanga Whakamaroke:Ka taea te whakamaroke i te HPMC mā te hau wera, te whakamaroke korehau, te whakamaroke hurihuri rānei. Me arotau te pāmahana me te roa o te whakamaroke kia kore ai e maroke rawa (he nui te makuku) me te maroke rawa (ka arahi pea ki te hekenga wera).
Te Mana Taiao:He mea tino nui te pupuri i tētahi taiao whakahaeretia me te iti o te haumākū i roto i te wāhi whakaputa. Tērā pea ka uru atu ki tēnei ngā whakamaroke haumākū, te hauhautanga, me te whakamahi i ngā pūoko makuku hei aroturuki i ngā āhuatanga o te hau i te wā e tukatuka ana.
Ko te nui o te makuku o HPMCi te nuinga o te wā ka taka ki roto i te awhe o te 7% ki te 10%, ahakoa ka rerekē pea i runga i te momo, te tono, me ngā tikanga rokiroki. He tawhā nui te nui o te makuku e pā ana ki ngā āhuatanga rheological, te wairewa, me te pumau o AnxinCel®HPMC. Me āta whakahaere me te aroturuki ngā kaihanga me ngā kaihanga i te nui o te makuku kia pai ai te mahi i roto i ā rātou tono motuhake.
