1. Kua wehea te HPMC ki te momo inamata me te momo marara tere.
Ko te momo horapa tere HPMC he reta S hei whakamutunga. Me tāpiri te Glyoxal i te wā o te tukanga whakaputa.
Kāore he reta e tāpirihia ana e te momo HPMC tere-marara, pērā i te "100000" ko te tikanga "100000 matotoru HPMC tere-marara".
2. He rerekē ngā āhuatanga mēnā he S, kāore rānei
Ka tere te horapa o te HPMC i roto i te wai matao, ka ngaro atu i roto i te wai. Kāore he matotoru o te wai i tēnei wā nā te mea ka horapa noa te HPMC i roto i te wai, kāore i te tino memeha. I muri i te rua meneti pea, ka piki haere te matotoru o te wai, ka hanga he wai matotoru mārama. He kōroiti matotoru.
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 i roto i te paura putty me te moata. I roto i ngā kāpia wai, ngā peita me ngā taputapu horoi, ka puta pea he puranga, ā, ka kore e taea te whakamahi.
He whānuitia ngā whakamahinga o te HPMC tere horapa. Ka taea te whakamahi mō te paura putty, te moata, te kāpia wai, te peita, me ngā taputapu horoi, me te kore he ārai.
tikanga whakarewa
1. Tangohia te nui o te wai wera e hiahiatia ana, ringihia ki roto i tētahi ipu ka whakamahana kia neke atu i te 80℃, 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 hei hanga i tētahi parai ōrite. Whakamataohia te wai i a koe e whakaoho ana.
2. Whakamahanahia rānei 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, whakaohokia tonutia, ā, whakamataohia te ranunga.
3. He angiangi te rahi o te mata o te cellulose, ā, he rite tonu ki ngā matūriki iti i roto i te paura kua whakaohokia. Ka tere te memeha ina pā ki te wai hei hanga i te matotoru e hiahiatia ana.
4. Tāpirihia mārire, kia ōrite hoki te cellulose i te pāmahana rūma, me te whakaoho tonu kia puta rā anō he wai mārama.
He aha ngā āhuatanga e pā ana ki te pupuri wai o te hydroxypropyl methylcellulose?
Ko te pupuri wai o ngā hua HPMC hydroxypropyl methylcellulose ka pāngia e ēnei āhuatanga:
1. Te ōritetanga o te cellulose ether HPMC
He ōrite te tohatoha o ngā rōpū methoxy me te hydroxypropoxy HPMC e tauhohe ōrite ana, ā, he nui te pupuri wai.
2. Te pāmahana wera o te cellulose ether HPMC
Ka teitei ake te pāmahana o te tiēre kawe wera, ka teitei ake te tere pupuri wai; engari, ka iti iho te tere pupuri wai.
3. Te matotoru o te cellulose ether HPMC
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.
Te nui o te tāpiri HPMC cellulose ether
Ko te nui ake o te nui o te cellulose ether HPMC i tāpirihia, ko te teitei ake o te tere pupuri wai me te pai ake o te pānga pupuri wai.
I te awhe o te 0.25-0.6%, ka tere piki te auau pupuri wai i te pikinga o te nui o te tāpiri; ina piki tonu te nui o te tāpiri, ka puhoi haere te ia pikinga o te auau pupuri wai.
