Ko te Hydroxypropyl Methyl Cellulose (HPMC, Hydroxypropyl Methyl Cellulose) he rauemi pūmua e whakamahia whānuitia ana i roto i te paura putty. He pai tōna wairewatanga ki te wai, he piri, he pupuri wai, he matotoru, he hanga kiriata me te whakahinuhinu, nō reira he mahi nui tāna i roto i te paura putty.
1. Te pupuri wai
Ko tētahi o ngā mahi tino nui a te HPMC i roto i te paura putty ko te pupuri i te wai. Ka maroke te paura putty i muri i te paninga, ko te HPMC ia ka pupuri i te makuku me te whakaroa i te wā maroke. Mā tēnei āhuatanga ka roa ake te wā mahi o te paura putty i te wā e whakamaroke ana, he mea pai tēnei mō te hanganga. Ka ārai hoki te pupuri wai i te pakaru o te paparanga putty, ka whakapai ake i te kaha me te pumau o te hua kua oti.
2. Te Whakamātotoru
Hei whakamātotoru, ka taea e te HPMC te whakanui ake i te matotoru o te paura putty, kia momona ake ai, kia ōrite ai hoki te paura putty ina pania. Ka taea e ia te whakarite i te matotoru o te paura putty kia kore ai e totohu te rauemi me ngā uauatanga hanga, kia taea ai te paninga ōrite o te paura putty ki te pakitara me te kore e rere, kia pai ake ai te kounga o te hanga.
3. Ngā āhuatanga hanga kiriata
Ka taea e te kiriata i hangaia e te HPMC i te wā whakamaroke te whakanui ake i te kaha me te roa o te mata o te paura putty. He mea nui ngā āhuatanga hanga kiriata ki te kaha o te paura putty ki te ātete i te pakaru me te kakahu. Ehara i te mea ka taea e tēnei hanganga kiriata te ārai i ngā pakaru o te mata o te paparanga putty anake, engari ka whakarei ake hoki i te ātete o te paparanga putty ki te taiao, pērā i te ātete UV me te ātete makuku.
4. Te hinu whakahinuhinu
He pai te whakahinuhinu o te HPMC, ā, ka āwhina i te whakapai ake i te mahi hanga o te paura putty. I te wā e whakaranua ana, e hangaia ana te paura putty, mā te pānga whakahinuhinu o te HPMC ka māmā ake te whakaoho i te paura putty kia ōrite, kia maeneene hoki te paninga ki te pakitara. Ehara i te mea ka māmā ake te hanga, engari ka whakaitihia hoki te pakaru me te haehae o ngā taputapu hanga.
5. Te pumau
Ka taea e te HPMC te whakapai ake i te pumau o te paura putty. Ka taea e ia te ārai i te paura putty mai i te taunga, te kohikohi me ētahi atu raruraru i te wā rokiroki, ā, ka whakarite hoki i te pumau mō te wā roa o te hua. Mā tēnei pānga pumau o te HPMC ka ārai i te whakaoho pinepine o te paura putty i mua i te whakamahinga, ā, ka mau tonu te kounga ōrite.
6. Whakapai ake i te mahi ārai-paheke
I te hanganga o ngā pakitara poutū, ki te kore e pai ngā āhuatanga ārai-paheke o te paura putty, ka ngāwari ki te totohu me te totohu. Ko ngā pānga piri me te matotoru o te HPMC ka tino whakapai ake i te mahi ārai-paheke o te paura putty, kia taea ai te piri pūmau ki te pakitara hei hanga i tētahi mata papatahi, maeneene.
7. Whakapai ake i te āheinga hanga
Mā te noho mai o te HPMC ka māmā ake te hanga i te paura putty, ka whakaiti i te piri o ngā taputapu, ā, ka pai ake te whai huatanga o te hanga. Ka taea e ia te whakaiti i te tūponotanga o te piri o te paura putty ki ngā taputapu i te wā o te hanganga, ka whakaiti i te ātete i te wā e whakamahia ana, ā, ka whakapai ake i te whakamarie me te pānga o te hanganga.
8. Whakatikatikahia ngā hāora whakatuwheratanga
Ka taea e te HPMC te whakarite i te wā whakatuwheratanga o te paura putty. Ko te wā whakatuwheratanga e pā ana ki te wā ka taea te whakarite me te kuti i te paura putty i muri i te hanganga. Mā te whakahaere i te nui o te HPMC i tāpirihia, ka taea te whakaroa, te whakapoto rānei i te wā whakatuwheratanga o te paura putty kia urutau ki ngā hiahia hanganga rerekē.
9. Whakapai ake i te ātete pakaru
Nā te kaha o te HPMC ki te whakamātotoru me te pupuri wai, ka taea e ia te ārai i te mimiti me te ngatata o te paura putty nā te nui o te wai e ngaro ana i te wā whakamaroke. Ka taea e ia te whakarato i te ngāwari tika, ka taea ai e te paparanga putty maroke te ātete i te ahotea o waho me te whakaiti i te puta o ngā ngatata o te mata.
10. Whakapai ake i te ātete ki te huarere
Ka taea e te HPMC te whakapakari i te ātete huarere o te paura putty, me te ārai i te koroheketanga me te pirau o te paparanga putty i roto i ngā taiao uaua. Nā ngā āhuatanga hanga kiriata me te pumau o te HPMC, ka taea e ia te ātete pai ki te horo ultraviolet me ngā huringa haumākū, ka roa ake te ora o te paura putty.
He maha ngā mahi a te HPMC i roto i te paura putty. Mai i te pupuri wai, te whakamātotoru, me te hanganga kiriata ki te whakarei ake i te mahi hanga me te whakapai ake i te ātete ki te pakaru, he mahi nui tāna ki te mahi me te pānga hanga o te paura putty. Mā tana whakamahinga ka pai ake te mahi hanga, te pumau me te roa o te paura putty, ka whakarato i te taurangi nui mō te hanganga pakitara. I roto i te poto, he wāhanga tino nui te HPMC o te paura putty, ā, he mahi nui tāna ki te whakapai ake i te mahi whānui o te paura putty.
