Metila Hauwaitoitirīti Hēroro (MHEC)He matū kore-ionic cellulose e whakamahia whānuitia ana, e whakamahia whānuitia ana i roto i ngā matū hanga. He tino pai ōna āhuatanga mō te whakamātotoru, te pupuri wai, te hanga kiriata, te here, me te horapa, ā, he mea nui tēnei hei tāpiri i roto i ngā moata ranunga maroke, ngā piripiri taera, ngā paura putty, ngā rauemi gypsum, me ngā pūnaha paninga.
1. Te Whakamatotoru me te Mana Rheology
I roto i ngā hua o te moata sima me te gypsum, ka whakamātotoru te MHEC mā te hanga hononga hauwai ki ngā ngota wai, ka whakanui ake i te matotoru o te otinga. Ka whakapai ake tēnei āhuatanga i te rere me te ngāwari o te mahi o te paru, ka ārai i te wehewehe, i te toto rānei i te wā e whakaranu ana me te paninga. I roto i ngā piri taera me ngā paura putty, mā te tāpiri o te MHEC ka māmā ake te paninga o ngā rauemi, ka hanga he mata ōrite ake, ā, ka whakapai ake i te pai o te hanga.
2. Te Pupuri Wai me te Whakamaroke Whakaroa
Ko tētahi o ngā āhuatanga tino rongonui o te MHEC ko tōna pupuri wai pai rawa atu. I te wā e hangaia ana te moata sima me ngā hua gypsum, ka taea e te mimiti tere o te wai te arahi ki te kore e ranea te kaha, te pakaru, te heke rānei o te piri. Ka hangaia e te MHEC he kiriata ngota rite i roto i te pūnaha, ka whakaroa i te mimiti wai, ā, ka whakarite kia makuku katoa te sima me te whakapakeke katoa o te gypsum, ā, ka whakarei ake i te kaha me te roa o te rauemi. He mea tino nui tēnei āhuatanga i roto i ngā taiao hanga wera, maroke.
3. Te Whakapai Ake i te Āhua Mahi
Ka whakapai ake te MHEC i te kaha o ngā matū hanga. Ka whakarei ake i te hinu whakahinuhinu o te moata, ka maeneene ake i te wā e waruhia ana, e werowerohia ana hoki, ka whakaiti i te ātete hanga me te kaha o te mahi. Hei tāpiri, nā ōna āhuatanga thixotropic, ka mau tonu te matotoru o te MHEC i te wā e tū ana i te wā hanga, ka ārai i te totohu, te maturuturu rānei. Ina pāngia e ngā kaha o waho, ka heke tōna matotoru, ka māmā ake te tono me te horapa. Ka whakarei ake tēnei whakatikatika rheological i te wheako hanga.
4. Te Kaha o te Hononga kua Whakapaitia
I roto i ngā piripiri taera, ngā pūnaha whakamarumaru pakitara o waho, me ngā moata whakaōrite-ake, ka whakapai ake te MHEC i te pupuri wai me te mākū o te moata, ka whakarei ake i tōna piri ki te turanga me ngā rauemi mata. Mā te tāpiri i te MHEC ki te piripiri taera ka whakarite kia nui te wā tuwhera mō ngā taera i te wā tāutanga, ka ārai i te poka, i te hinga rānei nā te tere o te ngaronga wai. Hei tāpiri, ko te tauhohenga makuku ōrite i roto i te moata ka whakanui ake i te kaha o te here, ka whakarite i te hanganga me te haumaru o te whare.
5. Te Whakapai Ake i te Āhuarangi me te Kounga o te Mata
Ka āwhina a MHEC ki te hanga i tētahi hanganga mata ōrite, matotoru hoki i roto i ngā pūnaha moata me te peita, ā, ka whakaiti i te tūponotanga o ngā pakaru. I roto i ngā paninga paura putty me ngā pakitara o waho, ka whakarei ake a MHEC i ngā āhuatanga hanga kiriata me te maeneene, ka hua ake he mata pakitara maeneene, he pai hoki, ā, ka whakarato i tētahi turanga pai mō ngā paninga o muri mai. Hei tāpiri, ka whakapai ake i te ātete huka-rewa me te ātete huarere o te pūnaha, ka whakarite i te mahi pumau i roto i ngā āhuarangi rerekē.
6. Ngā Tauira Taupānga
Ngā Piripiri Taera me ngā Grout: Mā te MHEC ka mau te wai me te ngāwari o te mahi o ngā piripiri taera, ka roa ake ai te ora mahi me te whakapai ake i te kaha o te piri.
Ngā Paura Whakapūtā me ngā Rauemi Whakatakoto Pakitara: Ka whakarei ake te MHEC i te maeneene me te pupuri wai i te wā e waruhia ana, ka ārai i te kirikiri me te ngatata. Ngā hua kei roto i te gypsum: Pērā i te pāreti whakataurite-ake gypsum me te pāreti gypsum: Ka whakapai ake te MHEC i te mahi me te kaha, ka ārai i te ngaronga tere o te wai.
Te moata whakamarumaru pakitara o waho: Ka whakapai ake i te mahi a te moata, te pupuri wai, me te ātete ki te totohu, kia kaha ai te piri o te pūnaha.
Moata ranunga maroke: He whānuitia te whakamahinga i roto i te moata pereki, te moata paraikete, me te moata whakatika, kia pumau ai te mahi a te moata.
Ngā paninga hoahoanga: Ka whakamātotoru, ka marara, ka whakau hoki te MHEC i ngā paninga wai-pērā i te peita rapa, ka whakapai ake i te mahi me te kounga o te kiriata.
7. Te Whakataurite ki Ētahi Atu Etera Cellulose
I roto i ngā mahi matū hanga, ka whakaritea te MHEC ki te HPMC (hydroxypropyl methylcellulose). Ahakoa he rite ngā āhuatanga o ngā mea e rua, he pai ake te wairewa me te whai hua o te MHEC, ā, he tino pai mō ngā mahi e aro nui ana ki te utu. I tētahi atu taha, he pai ake te ātete ki te pāmahana teitei me te roa o te mau o te HPMC. Nō reira, i roto i ngā whakatakotoranga tuturu, ka tīpakohia te MHEC, te HPMC rānei, te huinga rānei o ngā mea e rua, i runga i ngā whakaritenga hanga me ngā whakaaro ōhanga hei whakatutuki i ngā hua tino pai.
Hei tāpiri matū hanga matua,MHEC, me ōna āhuatanga whānui o te whakamātotoru, te pupuri wai, te whakapai ake i te mahi, te whakanui ake i te piri, me te whakanui ake i te ātete ki te huarere, kua whānuitia te whakamahinga i roto i te whānuitanga o ngā tono, tae atu ki ngā piripiri taera, ngā paura putty, ngā hua gypsum, ngā moata whakamahana, me ngā paninga. Ehara i te mea ka arotau noa i ngā āhuatanga ā-tinana o ngā rauemi hanga engari ka whakarei ake hoki i te whai huatanga o te hanga me te kounga o te kaupapa whakamutunga. I te haere tonu o te whanaketanga o ngā rauemi hanga ki ngā rauemi matomato ake, he pai ake te taiao, me te mahi teitei ake, ka whānui ake ngā tirohanga tono a MHEC, ā, ka haere tonu te whakapūmau i tōna tūranga nui i roto i te umanga matū hanga.
