Te Whakapakari Whakamaero Hydroxypropyl Methyl Cellulose Etera HPMC
Viscosity Teitei HPMC hydroxypropyl methyl cellulose Whakamatotoru Mo te paura putty:
1) Te ahua: Ko te HPMC he ether cellulose nonionic, he paura ma-hinahina-ma, he granule ranei, he hongi me te kore kakara, he wairewa i roto i te wai matao, waikawa acetic glacial, ethanol, methanol me te propylene glycol, he iti te wairewa i roto i te acetone i runga i te tohu o te whakakapi, kare e rewa ki te wai wera, ethylene glycol me te toluene. Ka rewa te HPMC ki te ranunga o te 10% methanol me te 90% methylene chloride hei hanga wairewa colloidal.
2) Ko te otinga o te HPMC he mahi mata, he maamaa teitei, he mahi pumau. Ina whakamahana i etahi paanga, ka pouri te wairewa, ka hangai ranei he riu karekau. Heoi, ka marama ano te otinga i muri i te whakamatao. Ko nga momo rereke rereke o te HPMC he rereke te pāmahana wai. He rereke te whakarewatanga ki te pokey. Ko te iti o te pokey, ka teitei ake te whakarewatanga. He rereke nga momo momo HPMC i etahi o nga taonga, a, ko te wairewatanga i roto i te wai kaore e pa ki te pH.
3) Te rahi o te matūriki: 100% tere haere i roto i te 80 mata.
4) Kiato kitea: 0.25-0.70 g/mL (te nuinga o te 0.5 g/mL), kiato motuhake 1.26-1.31mL.
5) Te pāmahana huringa tae: 190-200 ° C; Te pāmahana waro:280-300°C.
6) Te mata o te mata: 42-56 dyn/cm (2% wairewa wai).
7) Ko te teitei ake o te methoxy i roto i te HPMC, te iti iho o te mahana o te wai, me te teitei ake o te wairewa i roto i te wai me te mahi mata.
8) Ko etahi atu ahuatanga o te HPMC, hei tauira, te whakakaha i nga rawa, te pumau o te pH, te pupuri i te wai, te pai o te hanga kiriata, te pai o te marara me te kaha piri.

Kei roto i nga hua Youngcel nga momo hua wai katoa penei i te horoi o te papa, te horoi horoi me nga hua horoi rihi me te pH i waenga. 6- 8
TaiohiTeneil ka taea te whakamahi hei kaitao ki te whakatika i te rheology o nga kai horoi wai, te whakatika ki te ahua e hiahiatia ana me te riterite pai.
TaiohiTeneil ka taea e nga tauira viscous me nga kai horoi kiri te whai hua ake, me te pai ake, na te mea TaiohiTeneil ka waiho nga kai horoi kiri ki runga i te mata ka mahi mo te wa roa, no reira ka pai ake te horoi.
