Ko te sublimedgrade hydroxypropyl methyl cellulose he pūmua hangai i hangaia mā te whakarerekētanga matū o te cellulose tūturu. Ko te cellulose ether he mea hanga mai i te cellulose tūturu, he rerekē te hanga cellulose ether me te pūmua hangai, ko tōna rauemi taketake ko te cellulose, he pūhui pūmua tūturu. Nā te āhua motuhake o te hanganga cellulose tūturu, kāore te cellulose tonu e kaha ki te tauhohe ki te kaihoko etherifying, engari i muri i te tukatuka i te kaihoko pupuhi, ka whakangaromia te mekameka i roto i ngā here hauwai kaha i waenganui i te mekameka ngota, ka tukuna te mahi o ngā rōpū hydroxyl ki roto i te taura muka ka taea te tauhohe ki te alkali, ka tauhohe i muri i te kaihoko etherification he turanga OH ki roto i te turanga cellulose ether OR.
Te matotoru motuhake o te 200 mano
He mā, he paku kōwhai te paura o te hydroxypropyl methyl cellulose, ā, kāore he kakara, kāore he reka, kāore he paitini. Ka taea te rewa ki te wai matao me te ranunga matū waro o ngā whakarewa, ka hanga he otinga matotoru mārama. He nui te māramatanga o te mata o te wai, he pumau te kaha, ā, kāore e pāngia e te PH te rewa ki te wai. He pānga whakamātotoru me te ārai huka i roto i te hopi horoi me te wai kaukau, ā, he pupuri wai me te āhuatanga hanga kiriata pai mō te makawe me te kiri. Nā te pikinga ake o ngā rauemi mata taketake, ka taea te whakamahi i te cellulose (whakamātotoru ārai huka) i roto i te hopi horoi me te wai kaukau i te utu iti ake, ā, ka tutuki tonu ngā hua e hiahiatia ana.
Ngā āhuatanga me ngā painga o te HPMC cellulose kounga Sublimed:
1. He iti te riri, he teitei te pāmahana me te taatai;
2. He whānui te pumau o te pH, kua whakamanahia i roto i te awhe pH o te 3-11;
3. Whakanuia te whakaaro nui;
4 whakanui me te whakau i ngā mirumiru me te whakapai ake i te kiri
kare ā-roto:
5. Whakapai ake i te tere o te pūnaha.
Ngā tono HPMC muka whakahīhī:
Whakamahia mō te hopi horoi makawe, te horoi tinana, te horoi kanohi, te hinu kiri, te kirimi, te toner, te whakangawari makawe, ngā hua hanga āhua, te paraihe niho, te horoi waha, te wai mirumiru taonga takaro.
Te tūranga HPMC cellulose kounga-whakauru.
Te tono whakapaipai, e whakamahia ana mō te whakamātotoru whakapaipai, te pahuka, te pumau
te whakapai ake i te mahi whakaemulsification, te marara, te piri, te kiriata me te pupuri wai, ngā hua matotoru teitei e whakamahia ana mō te whakamātotoru, ngā hua matotoru iti e whakamahia ana mō te marara whakatārewatanga me te kiriata.
Hangarau HPMC cellulose kounga-whakauru:
Ko te matotoru o te muka hydroxypropyl methyl mō te ahumahi matū o ia rā ko te 100,000, 150,000, 200,000 me ētahi atu.
