Whakaranuhia te wai parai me te hātea. Ka ahatia?
Tuhinga
Te hanganga o nga waahanga me nga reagents
He polyglycols - he momo polymeric o te waipiro polyhydric (ethylene glycol me te propylene glycol), polyesters waikawa boric me te whakarereke. Kei roto i te maaota te hypochlorite, te hauwai me te konupūmā pūhaumāota. Ko te reagent matua i roto i te wai pakaru ko te polyethylene glycol, me te hātea - hypochlorite. He ahua wai ano o nga hua o te whare kei roto te maaota, kei roto i te konutai hypochlorite te mahi hei kaiwhakaora waiora.
Whakaahuatanga o te tukanga
Mena ka whakaranua e koe te hātea me te wai parai, ka kite koe i te tauhohenga kaha me te nui o te tuku hau. Kaore e puta tonu te taunekeneke, engari i muri i te 30-45 hēkona. Whai muri i te hanganga o te waiariki, ka mura nga hua hau, ka mutu he pahū.
Kaore i te tūtohutia kia whakahaerehia nga whakamatautau i te kainga. Mo te mahi, me whakamahi nga taputapu whakamarumaru, me kawe te hohenga ki roto i te kohu kohu, ki te waahi tuwhera ranei i te waahi haumaru.
tikanga tauhohenga
I roto i te whakamatautau, ka whakamahia te waiu hou kua rite. Engari i te hātea, ka taea e koe te whakamahi i te konutai hypochlorite, kei roto ki te 95% te maota e waatea ana. I te timatanga, ka pirau te tote hypochlorite me te hanganga o te maota ngota:
NaOCl → NaO+ + CI-
Ko te katote chloride hua ka pupuhi i te ngota ngota o te ethylene glycol (polyethylene glycol), e arai ana ki te whakakore i te hanganga polymer me te tohatoha ano i te kiato irahiko. Ko te mutunga, ka wehea te monomer, formaldehyde, i te mekameka waerau. Ka huri te ngota ngota ethylene glycol ki te tuwhena hiko, ka tauhohe ki tetahi atu katote chloride. I te wa e whai ake nei, ka wehea te acetaldehyde mai i te polymer, ka mutu ka noho tonu te alkene ngawari, ethylene. Ko te kaupapa wehewehe whanui e whai ake nei:
Polyethylene glycol ⇒ Formaldehyde; Acetaldehyde; Ethylene
Ko te whakangaromanga kino o te ethylene glycol i raro i te mahi o te chlorine ka haere tahi me te tukunga o te wera. Heoi, he haurehu muramura te ethylene me te formaldehyde. No reira, na te whakamahana i te ranunga tauhohenga, ka mura nga hua hau. Mēnā he tere rawa te tauhohenga, ka puta he pahū nā te roha ohorere o te ranunga hau-wai.
He aha te tauhohenga kaore e puta?
I te nuinga o nga wa ka ranuhia te wai parai me te hātea, kaore he mea e kitea. Ka tupu tenei mo nga take e whai ake nei:
- Kua whakamahia te waiu o te whare tawhito
Ina penapena ki waho, ka puhoi haere te konupūmā hypochlorite ki te konupūmā pākawa waro me te konupūmā pūhaumāota. Ko te ihirangi o te māota kaha kua heke ki te 5%.
- Te pāmahana iti
Mo te tauhohenga ka puta, me whakamahana te wai parai ki te mahana o te 30-40 ° C
- Kaore i nui te wa kua pahemo
Ka puta he tauhohenga mekameka tuwhena me te piki haere o te tere. Kia 1 meneti pea ka puta nga huringa tirohanga.
Inaianei kei te mohio koe ka aha mena ka konatunatua te hātea ki te wai pakaru me te pehea o te taunekeneke.
