Kei raro nei he whakataki poto mō ngā tikanga mahi, ngā momo me te aromatawai kua whakarārangihia mō ngā momo matū tiaki.
1.Ko te tikanga mahi whānui ongā mea tiaki
Ko ngā matū tiaki he matū e āwhina ana ki te patu, ki te aukati rānei i ngā mahi a ngā moroiti i roto i ngā mea whakapaipai, me te pupuri i te kounga whānui o ngā mea whakapaipai mō te wā roa.
Heoi, me mārama ko ngā mea tiaki ehara i te patu huakita – kāore he pānga patu huakita kaha, ā, ka mahi anake ina whakamahia i te nui o te rahinga, ina pā tika rānei ki ngā moroiti.
Ka aukati ngā matū tiaki i te tipu o ngā moroiti, ka aukati hoki i te hanganga o ngā whākōkī pākia nui, tae atu ki te aukati i te hanganga o ngā pūmua i roto i ngā wāhanga nui o te pūtau, i te hanganga rānei o te waikawa karihi.
2.Ngā āhuatanga e pā ana ki ngā mahi a ngā matū tiaki
He maha ngā āhuatanga e whai wāhi ana ki te pānga o ngā matū tiaki. Ko ētahi o ēnei ko;
a.Te Pānga o te pH
Ka whai wāhi te panoni o te pH ki te memeha o ngā matū tiaki waikawa waro, ā, ka pā ki te whai huatanga whānui o ngā matū tiaki. Hei tauira, i te pH 4 me te pH 6, he tino pumau te 2-bromo-2-nitro-1,3-propanediol.
b.Ngā pānga o te tiēre me ngā matūriki totoka
Ko te koalin, te konupora silicate, te konumohe me ētahi atu, he matūriki paura kei roto i ētahi mea whakapaipai, e mimiti ana i te matū tiaki, ā, ka ngaro te mahi a te matū tiaki. Heoi, he whai hua anō hoki ētahi ki te mimiti i ngā huakita kei roto i te matū tiaki. Waihoki, ko te whakakotahitanga o te tiēre polymer wairewa-wai me te matū tiaki ka whai wāhi ki te whakaiti i te kukū o te matū tiaki toenga i roto i ngā hanganga whakapaipai, ā, ka whakaitihia hoki te pānga o te matū tiaki.
c.Te pānga whakarewa o ngā matū horoi kore-ionic
Ko te whakarewatanga o ngā momo matū horoi pēnei i ngā matū horoi kore-ionic i roto i ngā matū tiaki ka pā ki te mahi whānui o ngā matū tiaki. Heoi, e mōhiotia ana he nui ake te kaha whakakore o ngā matū horoi kore-ionic wairewa-hinu pēnei i te HLB=3-6 i runga i ngā matū tiaki ki te whakataurite ki ngā matū horoi kore-ionic wairewa-wai me te uara HLB teitei ake.
d.Te pānga o te pirau o te matū tiaki
Tērā atu anō ngā āhuatanga pēnei i te wera, te mārama, e whai wāhi ana ki te pirau o ngā mea tiaki matū, ā, ka heke te pānga o te patu huakita. Heoi anō, ko ētahi o ēnei pānga ka hua ake he tauhohenga matū koiora hei hua o te whakahoromata me te patu huakita irahiko.
e.Ngā mahi kē atu
Waihoki, ko ētahi atu āhuatanga pēnei i te noho mai o ngā kakara me ngā kaihoko chelating me te tohatoha o ngā mea tiaki i roto i te hinu-wai e rua-wāhanga ka whai wāhi atu ki te whakaiti i te mahi a ngā mea tiaki ki tētahi taumata.
3.Ngā āhuatanga paturopi o ngā mea tiaki
He mea tika kia whakaarohia ngā āhuatanga patu huakita o ngā mea tiaki. Mēnā he nui rawa ngā mea tiaki i roto i ngā mea whakapaipai, ka tino whakapataritari, engari ki te kore e nui te kukū ka pā ki te mea patu huakita.ngā āhuatanga o ngā mea tiakiKo te tikanga pai rawa atu hei aromatawai i tēnei ko te whakamahi i te whakamātautau wero koiora e uru ana ki te kukū aukati iti rawa (MIC) me te whakamātautau rohe aukati.
Whakamātautau porowhita huakita: Ka whakamahia tēnei whakamātautau hei whakatau i ngā huakita me te harore e kaha ana ki te tupu tere i muri i te whakatipu i runga i tētahi papa e tika ana. Mēnā ka maturuturuhia he kōpae pepa tātari kua whakakiia ki te matū tiaki ki waenganui o te pereti papa ahurea, ka hangaia he porowhita huakita nā te urunga o te matū tiaki. Ina inehia te diameter o te porowhita huakita, ka taea te whakamahi hei ine i te whai huatanga o te matū tiaki.
Nā tēnei, ka taea te kī he tino whai hua te porowhita bacteriostatic mā te whakamahi i te tikanga pepa me te diameter >=1.0mm. Ko te MIC te mea iti rawa te kukū o te matū tiaki ka taea te tāpiri ki roto i te reo hei aukati i te tipu o te moroiti. I roto i tēnei āhuatanga, he iti ake te MIC, he kaha ake ngā āhuatanga patu huakita o te matū tiaki.
Ko te kaha, te pānga rānei o te mahi patu huakita ka whakaatuhia i te nuinga o te wā i roto i te ahua o te kukū aukati iti rawa (MIC). Mā te mahi pera, ka whakatauhia he mahi patu huakita kaha ake e te uara iti o te MIC. Ahakoa kāore e taea te whakamahi i te MIC hei wehewehe i waenga i te mahi patu huakita me te mahi patu huakita, e mōhiotia whānuitia ana he pānga patu huakita ngā surfactants i te kukū iti me te pānga whakamate huakita i te kukū teitei.
Ina hoki, i ngā wā rerekē, ka puta ngātahi ēnei mahi e rua, ā, he uaua ki te wehewehe i a rāua. Nā konei, ka tapaina rāua ko te patu huakita, ko te patu huakita rānei.
