I roto i ngā mahi hanga hou, ka pā tika te mahi a te moata ki te kounga me te whai huatanga o te kaupapa. Hei whakapai ake i te pupuri wai, te ngāwari o te mahi, me te piri o te moata,hydroxypropyl methylcellulose (HPMC)e whakamahia whānuitia ana i roto i ngā pūnaha moata ranunga maroke, pērā i ngā piripiri taera, ngā moata pāreti, ngā moata whakataurite-ake, me ngā moata whakamahana wera. Hei pūmua wairewa-wai tino whai hua, ka whakapai ake te HPMC mō te moata i te mahi moata mā tōna hanganga ngota ahurei me ngā āhuatanga ā-tinana me te matū, ka waiho hei tāpiri matua nui i roto i ngā hanganga moata hou.
1.He tino pai te pupuri wai a te HPMC. I roto i ngā pūnaha moata, ka hangaia e te HPMC he kiriata polymer matotoru ki runga i te mata o ngā matūriki sima, ka whakaiti i te ngaronga wai i te wā whakaranu, te tono, me te tautuhinga tuatahi. Ehara i te mea ka whakarite noa tēnei pupuri wai i te makuku o te sima, ka whakanui ake hoki i te whanaketanga kaha, engari ka ārai hoki i te maroke wawe me te pakaru i puta mai i te mimiti nui o te wai, i ngā pāmahana teitei rānei i roto i te paparanga turanga. Mō ngā hua pēnei i ngā piri taera me ngā paura putty e hiahia ana kia pania ki te paparanga angiangi, he mea tino nui te pupuri wai a te HPMC, ka roa ake te wā tuwhera me te wā whakatikatika, ka whakapai ake i te manawanui tono.
2.Ka taea e te HPMC te whakapai ake i ngā āhuatanga rheological me te ngāwari o te mahi o te moata. Mā te nui o te HPMC e tika ana ka taea te whakarei ake i te viscoelasticity o te pūnaha moata, ka whakawhiwhia he hinu whakahinuhinu me te thixotropy pai i te wā e whakaranu ana me te tono, ka ārai i te toto me te wehewehe, me te whakarite kia maeneene ake te parai me te paninga. Ka whakapai ake hoki i ngā āhuatanga ātete-paheke o te moata, ka whakarite kia kore e paheke, e neke rānei ngā taera, ngā papa whakamahana rānei i te wā e tono ana. Mā tēnei mana rheological o te HPMC ka taea e ngā kaiwhakauru te whakahaere ngāwari i te matotoru o te moata me te maeneene o te mata, ā, ka whakapai ake i te pai o te tono me te kounga o te hua whakamutunga.
3.He tino pai ngā āhuatanga whakamātotoru me te whakapūmau o te HPMC i roto i te moata. Nā te mea he wairewa pūmau te hanganga mekameka polymer i roto i te wai, ka taea e te HPMC te whakanui ake i te matotoru o te moata i ngā horopeta iti, ka ārai i te whakarōpūtanga me te taunga i te wā rokiroki me te tono. Ehara i te mea ka whakapai ake i te pumau me te ōritetanga tono o te moata ranunga maroke anake, engari ka āwhina hoki ki te whakapai ake i te rokiroki me te mahi takai o te hua.
4.Ka whakarei ake hoki te HPMC i te ātete ki te here me te pakaru o te moata. Ka whakaatuhia e te kiriata polymer e hangaia ana e ia tētahi taumata o te ngāwari me te pakari, ka mahi hei piriti i muri i te whakapakeketanga o te moata, ka whakaiti i ngā pakaru moroiti i puta mai i te ahotea whakaheke. Hei tāpiri, ka whakapai ake i te kaha here ā-kanohi i waenga i te moata me te mata o te papa, o te taera rānei, ka roa ake te paparanga kua oti. He mea tino nui te pānga whakapakari here a te HPMC i roto i ngā pūnaha whakamarumaru pakitara o waho me ngā moata piri.
5.I roto i ngā mahi whaihua, he rerekē ngā whakaritenga HPMC e hiahiatia ana mō ngā momo moata rerekē. Hei tauira, he maha ngā wā ka whakamahia e ngā piripiri taera te HPMC matotoru-waenga ki te teitei, tuku-pōturi hei whakarite i te ārai-paheke me te pupuri wai, ko ngā moata whakaōrite-ake he pai mō te HPMC matotoru-iti, tere-rewa hei pupuri i te rere me te tono maeneene. Mā te whiriwhiri tika i te matotoru, te taumata o te whakakapinga, me te āhua o te matūriki, ka taea e ngā kaihanga te whakatutuki i te taurite pai i waenga i te pupuri wai, te rere, me te kaha.
6. HPMCmō te moata, me ōna āhuatanga ahurei e pupuri ana i te wai, e whakamātotoru ana, e whakahinuhinu ana, e piri ana, kua noho hei tāpiri mahi matua mō te whakarei ake i te mahi hanga o te moata maroke-ranu. Ehara i te mea ka arotau noa i te wheako hanga engari ka whakapai ake hoki i te kounga me te roa o te kaupapa. I te whanaketanga o ngā rauemi hanga matomato me ngā moata mahi-teitei, ka haere tonu te whānui o te whakamahinga o te HPMC i roto i ngā rauemi hanga, ā, ko tōna auahatanga hangarau me te arotautanga hua ka noho hei huarahi nui mō te whakatairanga i te whakapai ake i te mahi a ngā rauemi hanga.
