He mahi ā-mata tō te HPMC, ā, ka taea e ia te whai wāhi ki te horapa i te wā e whakaoho ana, kia ōrite ai te ranunga o ngā wāhanga rerekē o te moata maroke, kia kore ai e taea te wehewehe me te whakarōpū i ngā rauemi. Ka taea hoki e tōna hanganga ngota pumau te whakapai ake i te pumau o te moata gypsum me te karo i ngā raruraru o te turuturu wai me te whakatō.

2.5. Whakapai ake i te piri me te kounga o te mata

Mā te nui o te AnxinCel® HPMC e tika ana ka taea te whakapai ake i te kaha o te here i waenga i te moata gypsum me te turanga, te rauemi hipoki rānei, ka āwhina i te moata kia piri pai i muri i te hanganga, ā, kia kore ai e taka ngāwari. I taua wā anō, mā te whakapai ake i ngā āhuatanga rheological o te paru ka āwhina hoki ki te hanga i te mata kia papatahi, kia maeneene hoki i muri i te paninga, kia pai ake ai te kounga o te hua kua oti.

3. Te horopeta kua tūtohutia me ngā whakaaro tono
