4. Tikanga whakarewanga Hydroxypropyl methylcellulose (HPMC):
Ina tāpirihia tika ngā hua hydroxypropyl methylcellulose (HPMC) ki te wai, ka rewa, kātahi ka memeha, engari he tino puhoi, he uaua hoki tēnei memeha. E toru ngā tikanga memeha e whakaarohia ana i raro nei, ā, ka taea e ngā kaiwhakamahi te whiriwhiri i te tikanga tino watea e ai ki tā rātou whakamahinga:
1. Tikanga wai wera: Nā te mea kāore te hydroxypropyl methylcellulose (HPMC) e rewa i roto i te wai wera, ka taea te horapa ōrite i te wāhanga tuatahi o te hydroxypropyl methylcellulose (HPMC) ki roto i te wai wera, ā, ina whakamataohia, e toru ngā tikanga noa e whakaahuatia ana penei:
1). Ringihia te nui o te wai wera e hiahiatia ana ki roto i te ipu, ka whakamahana kia 70°C pea. Tāpirihia mārire te hydroxypropyl methylcellulose (HPMC) me te whakaoho mārire, ka tīmata te hydroxypropyl methylcellulose (HPMC) ki te mānu i runga i te mata o te wai, kātahi ka hanga mārire hei paraoa pokepoke, ka whakamatao i te paraoa pokepoke i te wā e whakaoho ana.
2). Whakamahanahia te 1/3, te 2/3 rānei (te nui e hiahiatia ana) o te wai i roto i te ipu, ka whakamahana ki te 70°C. E ai ki te tikanga 1), whakamararatia te hydroxypropyl methylcellulose (HPMC) hei whakarite i te para wai wera. Kātahi ka tāpirihia te toenga o te wai matao, te wai huka rānei ki roto i te ipu, kātahi ka tāpirihia te para wai wera hydroxypropyl methylcellulose (HPMC) kua whakahuatia ake nei ki te wai matao, ka whakaohokia, kātahi ka whakamatao i te ranunga.
3). Tāpirihia te 1/3, te 2/3 rānei o te nui o te wai e hiahiatia ana ki roto i te ipu, ka whakamahana ki te 70°C. E ai ki te tikanga 1), whakamararatia te hydroxypropyl methylcellulose (HPMC) hei whakarite i te para wai wera; Kātahi ka tāpirihia te toenga o te wai matao, te wai huka rānei ki te para wai wera, ā, ka whakamataohia te ranunga i muri i te whakaoho.
2. Tikanga whakaranu paura: ka whakamararatia katoatia ngā matūriki paura hydroxypropyl methylcellulose (HPMC) me te nui ōrite, nui atu rānei o ētahi atu kai paura mā te whakaranu maroke, kātahi ka rewa ki te wai, kātahi ka taea te rewa i te hydroxypropyl methylcellulose Base cellulose (HPMC) me te kore e whakakotahi. 3. Tikanga whakamakuku whakarewa waro: ka whakamararatia i mua, ka rewa rānei te hydroxypropyl methylcellulose (HPMC) māku ki ngā whakarewa waro pērā i te etanoru, te ethylene glycol, te hinu rānei, kātahi ka rewa ki te wai. I tēnei wā, ka taea hoki te rewa maeneene i te hydroxypropyl methylcellulose (HPMC).
5. Ngā whakamahinga matua o te hydroxypropyl methylcellulose (HPMC):
Ka taea te whakamahi i te Hydroxypropyl methylcellulose (HPMC) hei whakamātotoru, hei whakamarara, hei whakapūhui me te hanga kiriata. Ka taea te whakamahi i ana hua ahumahi i roto i ngā matū o ia rā, ngā hikohiko, ngā kapia hangai, te hanga me ngā paninga.
1. Te whakapūhui whakatārewatanga:
I roto i te hanga o ngā kapia hangai pēnei i te polyvinyl chloride (PVC), te polyvinylidene chloride me ētahi atu copolymers, ko te polymerization whakatārewatanga te mea e whakamahia whānuitia ana, ā, he mea tika hei whakau i te whakatārewatanga o ngā monomers hydrophobic i roto i te wai. Hei polymer wairewa-wai, he pai te mahi mata o ngā hua hydroxypropyl methylcellulose (HPMC) ā, he mahi hei kaihoko tiaki colloidal, ka taea te aukati i te kohikohinga o ngā matūriki polymer. I tua atu, ahakoa he polymer wairewa-wai te hydroxypropylmethylcellulose (HPMC), he paku wairewa hoki i roto i ngā monomers hydrophobic, ā, ka whakanui ake i te porosity o ngā monomers i hangaia ai ngā matūriki polymeric, kia taea ai e ia te whakarato i ngā polymers he kaha pai ki te tango i ngā monomers toenga me te whakarei ake i te mimiti o ngā plasticizers.
2. I roto i te hanganga o ngā rauemi hanga, ka taea te whakamahi i te hydroxypropyl methylcellulose (HPMC) mō:
1). He mea whakapiri me te mea whakakī mō te rīpene piri e hangai ana ki te gypsum;
2). Te herenga o ngā pereki, ngā taera me ngā turanga i hangaia ki te sima;
3). He mea hanga ki te papa paraikete;
4). Pāreti hanganga i hangaia ki te sima;
5). I roto i te tauira o te peita me te tango peita.
