Te Waikawa Waikawa Metilururo (HPMC)He matū pūmua wairewa-wai te mea nei, i whiwhihia mā te whakarerekē matū i te cellulose taiao. E whakamahia nuitia ana i roto i ngā mara rongoā, kai, whakapaipai, me te hanga whare, ā, he tino pai ngā āhuatanga pēnei i te whakamātotoru, te hanga kiriata, te whakaemulsification, me te pumau.
1. Te kaupapa whakarite
He matū whai kiko te Hydroxypropyl methylcellulose, ā, ko tōna wairewatanga te mea nui e pāngia ana e ngā matū hydroxypropyl me ngā matū methyl i roto i te ngota. Ka whakanui ake te rōpū methyl i tōna wairewatanga wai, ko te rōpū hydroxypropyl ia ka whakanui ake i tōna tere wairewatanga i roto i te wai. I te nuinga o te wā, ka taea e AnxinCel®HPMC te wairewa tere i roto i te wai matao hei hanga i tētahi otinga colloidal ōrite, engari ka wairewa puhoi i roto i te wai wera, ā, ka ngāwari te kohikohi o ngā matū kirikiri i te wā wairewatanga. Nō reira, me aro nui ki te whakahaere i te pāmahana wairewatanga me te tukanga wairewatanga i te wā whakarite.
2. Te whakarite rauemi mata
Paura HPMC: Tīpakohia te paura HPMC me ngā matotoru rerekē me ngā nekehanga whakakapinga e ai ki ngā whakaritenga whakamahinga. Ko ngā tauira noa ko te matotoru iti (taumaha ngota iti) me te matotoru teitei (taumaha ngota teitei). Me hangai te kōwhiringa ki ngā hiahia o te hanganga motuhake.
Whakarewa: Ko te wai te whakarewa e whakamahia whānuitia ana, inā koa i roto i te whakamahinga o ngā rongoā me ngā kai. E ai ki ngā whakaritenga whakarewa, ka taea hoki te whakamahi i te ranunga o te wai me ngā whakarewa waro, pērā i te wairewa whakaranu etanoru/wai.
3. Tikanga whakarite
Te pauna HPMC
Tuatahi, paunatia tika te paura HPMC e hiahiatia ana kia rite ki te kukū o te otinga hei whakarite. Ko te whānuitanga kukū o te HPMC he 0.5% ki te 10%, engari me whakarerekē te kukū motuhake kia rite ki te kaupapa me te matotoru e hiahiatia ana.
Te whakarewatanga i mua i te whakamakuku
Hei ārai i te kohikohinga o te paura HPMC, ka whakamahia te whakarewanga i mua i te whakamakuku. Ko te mahi motuhake ko: tauhiuhia te paura HPMC kua paunatia kia ōrite ki roto i tētahi wāhanga o te whakarewa, whakaoho mārie, kātahi ka whakapakia te paura HPMC ki te iti o te whakarewa i te tuatahi kia hanga he āhua māku. Mā tēnei ka ārai i te kohikohinga o te paura HPMC, ā, ka whakatairanga i tōna horapa ōrite.
Te tukanga whakarewa
Tāpirihia mārire te toenga o te whakarewa ki te paura HPMC mākū, ā, me whakaoho tonu. Nā te mea he pai te wairewa o te HPMC ki te wai, ka tere te memeha o te wai me te HPMC i te pāmahana rūma. Kaua e whakamahi i te kaha kutikuti nui rawa i te wā e whakaoho ana, nā te mea ka puta he mirumiru i te whakaoho kaha, ka pā ki te mārama me te ōritetanga o te otinga. I te nuinga o te wā, me pupuri te tere whakaoho ki te awhe iti kia pai ai te memeha.
Whakahaere pāmahana
Ahakoa ka taea te whakarewa i te HPMC ki te wai matao, ki te puhoi te tere whakarewatanga, ka taea te whakamahana tika i te otinga. Me whakahaere te pāmahana whakamahana i waenga i te 40°C me te 50°C kia kore ai e tino teitei ngā pāmahana e puta ai he huringa ki te hanganga ngota, he huringa ohorere rānei ki te matotoru o te otinga. I te wā whakamahana, me haere tonu te whakaoho kia memeha rawa te HPMC.
Te whakamatao me te tātari
Kia oti te whakarewa, tukua te wairewa kia whakamatao noa ki te pāmahana rūma. I te wā e whakamatao ana, tera pea ka puta he iti o ngā mirumiru, o ngā poke rānei i roto i te wairewa. Mena e tika ana, ka taea te whakamahi i te tātari hei tātari hei tango i ngā matūriki totoka pea, hei whakarite hoki i te mārama me te mārama o te wairewa.
Te whakatikatika whakamutunga me te rokiroki
Kia whakamatao te wairewa, ka taea te whakarerekē i tōna kukū kia rite ki ngā hiahia tūturu. Mēnā he nui rawa te kukū, ka taea te tāpiri i tētahi whakarewa hei whakawaiwai; ki te iti rawa te kukū, me tāpiri atu he paura HPMC. Kia oti te whakarite i te wairewa, me whakamahi tonu. Mēnā me rongoa mō te wā roa, me rongoa ki roto i tētahi ipu hiri hei karo i te mimiti wai, i te poke rānei o te wairewa.
4. Ngā Whakatūpato
Whakahaere pāmahana: Me karo i te pāmahana teitei i te wā e whakarewahia ana kia kore ai e pā ki te wairewatanga me te mahi a AnxinCel®HPMC. I ngā pāmahana teitei, ka memeha pea te HPMC, ka heke rānei tōna matotoru, ka pā ki tōna pānga whakamahinga.
Tikanga whakaoho: Kaua e kutikuti rawa, kaua hoki e tere rawa te whakaoho i te wā e whakaoho ana, nā te mea ka puta pea he mirumiru i te whakaoho kaha, ā, ka pā ki te mārama o te otinga.
Kōwhiringa whakarewa: Ko te wai te whakarewa e whakamahia whānuitia ana, engari i ētahi whakamahinga motuhake, ka taea te whiriwhiri i tētahi otinga whakaranu o te wai me ētahi atu whakarewa (pērā i te waipiro, te acetone, me ētahi atu). Ka pāngia te tere whakarewa me te mahi a te otinga e ngā ōwehenga whakarewa rerekē.
Ngā tikanga rokiroki: Me rongoa te otinga HPMC kua oti te whakarite ki te wāhi hauhautanga, maroke hoki, kia kore ai e roa te pānga ki te pāmahana teitei, ki te rā tika rānei, kia kore ai e rerekē te kounga o te otinga.
Ārai-kōpiripiri: Ina tāpirihia te paura ki te whakarewa, ki te tere rawa te tāpiri, ki te kore rānei e ōrite te rahi o te paura, ka ngāwari te hanga i ngā puku, nō reira me tāpiri mārire.
5. Ngā āpure tono
E whakamahia whānuitia ana te Hydroxypropyl methylcellulose i roto i ngā ahumahi maha nā tōna wairewatanga pai ki te wai me te hototahitanga ki te koiora:
Ahumahi rongoā: Hei hanga kiriata, hei whakapiripiri, hei whakamātotoru, hei kaihoko tuku-roa, me ētahi atu o ngā rongoā, he mea nui tana mahi i roto i te tukanga whakarite rongoā.
Ahumahi kai: Hei whakamātotoru, hei whakapūhui, hei whakaū, he maha ngā wā ka whakamahia i roto i te tukatuka kai, pērā i te aihikirīmi, ngā mea kakara, ngā inu, me ētahi atu.
Ahumahi hangahanga: Hei whakamātotoru mō ngā paninga me te moata whare, ka taea te whakapai ake i te piri me te rere o te ranunga.
Ngā Mea Whakapaipai: Hei whakamātotoru, hei whakaū me hei hanga kiriata, ka whakamahia i roto i ngā mea whakapaipai pērā i ngā kirīmi, ngā hopi horoi makawe, me ngā hua tiaki kiri hei whakapai ake i te kounga o te hua me te wheako kaiwhakamahi.
Te whakarite oHPMCHe tukanga e hiahia ana kia aro nui ki ngā taipitopito. I te wā o te tukanga whakarite, me whakahaere ngā āhuatanga pēnei i te pāmahana, te tikanga whakaoho, me te kōwhiringa whakarewa kia tino memeha ai, kia mau tonu ai te mahi pai. Mā te tikanga whakarite tika, ka taea te whakamahi whānui i te AnxinCel®HPMC i roto i ngā ahumahi maha, ā, he mea nui anō hoki tana mahi.
