1.HPMCkua wehea ki te momo tere me te momo horapa tere.
Ko te momo marara tere HPMC ka tāpirihia te reta S ki te whakamutunga, ā, me tāpiri te glyoxal i te wā o te tukanga whakaputa.
Kāore te momo inamata HPMC e tāpiri i ngā reta, pērā i te "100000" ko te tikanga "100000 matotoru".
2. He rerekē ngā āhuatanga mēnā he S, kāore rānei
Ka tere te horapa o te HPMC ina tūtaki ki te wai matao, ka ngaro atu ki roto i te wai. I tēnei wā, kāore he matotoru o te wai, nā te mea ka horapa noa te HPMC ki roto i te wai, kāore he wairewa tūturu. I muri i te rua meneti pea, ka piki haere te matotoru o te wai, ka hanga he kōroiti matotoru mārama.
Ka taea te whakamarara tere i te HPMC inamata ki roto i te wai wera i te 70°C pea. Ina heke te pāmahana ki tētahi pāmahana, ka puta mārire te matotoru kia puta rā anō he kōroiti matotoru mārama.
3. He rerekē te kaupapa mēnā he S, kāore rānei
Ka taea anake te whakamahi i te HPMC inamata mō te paura putty me te moata. Mō te kāpia wai, te peita me ngā hua horoi, ka noho te āhuatanga whakarōpū, ā, kāore e taea te whakamahi.
Tere te mararaHPMCHe whānuitia ngā whakamahinga, ā, ka taea te whakamahi i roto i te paura putty, te moata, te kāpia wai, te peita, me ngā hua horoi, me te kore he contraindications.
4. Tikanga whakarewa
4-1. Tangohia te nui o te wai wera e hiahiatia ana, maka ki roto i tētahi ipu ka whakamahana kia neke atu i te 80°C, kātahi ka tāpirihia mārire tēnei hua me te whakaoho mārire. Ka mānu te cellulose i runga i te mata o te wai i te tīmatanga, engari ka marara mārire kia hanga he parai ōrite. I whakamataohia te wairewa i a ia e whakaoho ana.
4-2. Tērā atu rānei, whakamahanahia te 1/3, te 2/3 rānei o te wai wera ki runga ake i te 85°C, tāpirihia te cellulose kia puta he ranunga wai wera, kātahi ka tāpirihia te toenga o te wai matao, me te whakaoho tonu, ā, whakamataohia te ranunga.
4-3. He angiangi te mata o te cellulose, ā, kei roto i te paura kua whakaohokia ōritetia hei matūriki iti takitahi, ā, ka tere te memeha ina tūtaki ki te wai hei hanga i te matotoru e hiahiatia ana.
4-4. Tāpirihia mārire, kia ōrite hoki te cellulose i te pāmahana rūma, me te whakaoho tonu kia puta he wai mārama.
5. He aha ngā āhuatanga e pā ana ki te pupuri wai o te hydroxypropyl methyl cellulose?
5-1. Te ōritetanga o te HPMC cellulose ether
Ka tohatohahia te HPMC, te methoxyl me te hydroxypropoxyl e tauhohe ana kia ōrite, ā, he teitei te tere pupuri wai.
5-2. Te pāmahana wera o te HPMC cellulose ether
Ka teitei ake te pāmahana o te tiēre wera, ka teitei ake te auau pupuri wai; ki te kore, ka iti ake te auau pupuri wai.
5-3. Te Matatini HPMC o te Cellulose Ether
Ina piki te matotoru o te HPMC, ka piki anō hoki te tere pupuri wai; ina tae te matotoru ki tētahi taumata, he ngawari noa te pikinga o te tere pupuri wai.
6. Te nui o te tāpiri o te cellulose ether HPMC
Ko te nui ake o te cellulose etherHPMCtāpiri atu, ka teitei ake te auau pupuri wai, ka pai ake hoki te pānga pupuri wai.
I te awhe o te 0.25-0.6%, ka tere te piki o te auau pupuri wai i te pikinga o te nui o te tāpiri; i te pikinga ake o te nui o te tāpiri, ka puhoi haere te ia o te pikinga o te auau pupuri wai.
