Hydroxypropyl methyl cellulose
Whakamātautau wā whakatakoto
Ko te wā whakatakoto o te raima e pā ana ki te wā whakatakoto o te sima, kāore i te nui te pānga o te kirikiri, nō reira ka taea te whakamahi i te wā whakatakoto o te moata hei whakakapi i te rangahau o te HPMC mō te wā whakatakoto o te raima kore-marara i raro i te wai, ko te awe o te ranunga nā te wā whakatakoto e te ōwehenga wai-sima o te moata, te pānga o te ōwehenga sima-onepu, nō reira, hei aromatawai i te awe o te HPMC ki te wā whakatakoto o te moata, me whakatika te ōwehenga wai-sima me te ōwehenga sima-onepu o te moata.
He hanganga rārangi te HPMC, he rōpū hydroxyl kei runga i te rōpū mahi, ka taea te hanga hononga hauwai me ngā ngota wai e whakaranu ana, ka whakanui ake i te matotoru o te wai e whakaranu ana. Ka kukume ngā mekameka ngota roa o te HPMC tetahi ki tetahi, kia honoa ai ngā ngota HPMC tetahi ki tetahi hei hanga i tētahi hanganga whatunga, ko te sima e whakaranu ana, ka takai i te wai. Nā te mea he hanganga whatunga te HPMC e hanga ana i te rite ki te kiriata angiangi me te pānga takai o te sima, ka ārai pai i te mimiti o te makuku i roto i te moata, ka aukati, ka whakaroa rānei i te tere makuku o te sima.
Whakamātautau whakaheke wai
He rite te āhuatanga toto-wai o te moata ki tērā o te raima, ka nui te taunga o te konganuku, ka piki ake te ōwehenga wai-sima o te paparanga o runga o te paru, ā, ka nui te mimiti kirihou o te paparanga o runga o te paru, ka pakaru rānei i te tīmatanga, ā, he ngoikore te kaha o te paparanga mata o te paru. Mai i te whakamātautau, ka kitea mēnā he nui ake te nui o te ranunga i te 0.5%, kāore he āhuatanga turuturu wai. Nā te mea inaHPMCIna konatunatua ki te moata, ka hangaia he kiriata me te hanganga whatunga e te HPMC, me te mimiti o te hydroxyl ki runga i te mekameka roa o ngā macromolecules, kia puta ai te flocculation i roto i te sima i roto i te moata me te wai whakaranu, kia mau ai te hanganga o te tinana moata. I muri i te tāpiri anō i te HPMC ki roto i te moata, ka puta he maha ngā mirumiru iti motuhake. Ka tohatohahia ēnei mirumiru ki roto i te moata, ā, ka ārai i te whakatakotoranga o te kohuke. He nui te pānga o te mahi hangarau a te HPMC o ngā rauemi sima, e whakamahia ana hei whakarite i ngā mea pēnei i te moata maroke, te moata polymer me ētahi atu rauemi hiato sima hou, kia pai ai te pupuri wai, te kirihou hoki.
