Kuti tione ngati pH wa posankha mankhwala zodzikongoletsera?

Inu mwina munamva zamalonda ndi sopo shawa angakhale angelo, kutafuna m'kamwa, ndipo kawirikawiri, creams, zachinsinsi mawu "Paix Ash." Kodi ndi zingati kwenikweni zofunika kwa ife posankha detergents ndi zodzoladzola? Tiyeni tiyang'ane pa izo mwanjira iyi, kuti poponya kulowa mankhwala "m'nkhalango." RN ku Latin - "pundus hydrogenium" - amatanthauza "kulemera kwa haidrojeni." Khalidwe limeneli pH limasonyeza mlingo wa soda pamaso pa njira iliyonse kapena olimba. Komanso malonda ntchito osakaniza bwino asidi-m'munsi ndi pH ndale.

"Sopo uphwetsa khungu ..." - ichi ndi uthenga waukulu wa mtengo gel osakaniza malonda shawa. Ndithudi, soda - zosakaniza chachikulu detergents - ali chotsatira. Komabe, kusiya kwathunthu cha soda ndi kosatheka, chifukwa anali ndi thandizo lake yagwa dothi. Popanda sopo sopo - sopo iliyonse, Ndi kuika chinenero Uthenga amakhala mchere womwe watha amenewa ake. Choncho, phindu pH limasonyeza mmene sopo ali mankhwala. Kumbukirani sukulu sayansi: sopo chimatha? Ndiko kulondola, chidulo. Choncho, ife kuzima nacho soda ndi viniga. Izi zinthu ziwiri zofunika pa mtundu woyera, onse ali wokondwa zimawononga pa khungu: umachititsa acid ndi Dries soda.

Chizindikiro pH mukhoza kulingalira ngati lonse ziro kwa 14. Pamene pH ndi wofanana ndi ziro, zikutanthauza kuti palibe soda ndi - asidi mtundu woyera. Ngati iye ali khumi - ndi zamchere achilengedwe. Mu madzi otchezedwa, tsono, pH ndi wofanana ndi ziwiri. Koyamba zikuoneka kuti isanu - ndi chizindikiro bwino bwino kwambiri asidi-m'munsi. Koma palibe - madzi kouma khungu, ndipo makamaka bwino maganizo amene, patapita kusambira yaitali kapena kusamba amamva ndi itch pa nsana wake. Kodi timapeza "pansi pakati", kuti amamva kuipa kwa asidi kapena soda m'lingaliro lenileni khungu lawo?

khungu wathu alinso pH yake phindu. Iwo Mitandadza mwa anayi ndi theka (anthu ndi khungu wochuluka) asanu ndi theka (youma khungu). Choncho, lolembedwa pa sopo, kirimu kapena gel osakaniza kwa shawa "pH moyenera" kwaife kuti mlingo wa hydrogen mankhwala si kuposa 4.5-5.0 14 kufika pamlingo. Chinthu chomwecho malonda chingamu: chimodzi kwambiri chifukwa kutafuna iwo - izo mwamsanga kubwezeretsa asidi-zamchere muyezo wa M'mimbamo m'kamwa pambuyo mowa chakudya. Koma kodi kutsuka? Izi kuchotsa fumbi ndi khungu akufa particles ndi pa nthawi yomweyo chapamwamba wosanjikiza khungu (zimene amatchedwa ukuchoka zochitika). The zopangitsa sebaceous secrete ndi mafuta acidic amene anachotsa osati kuposa soda.

Choncho, posankha sopo ndi detergents zina, munthu ayenera kuganizira zimene mukufuna kuti avule izi zoteteza asidi kubisa modzilemekeza. Pambuyo asidi kumathandiza imfa ya madzi, koma amateteza chapping, kuwala ultraviolet, kuipa kwa chilengedwe. Chinthu china, pamene zopangitsa sebaceous - mwachitsanzo, mu nthawi ya kusasitsa kugonana - kutulutsa mafuta kwambiri. Ndiye, pores kukhala yatsekera, zikubweretsa maonekedwe a ziphuphu zakumaso achinyamata ndipo ziphuphu zakumaso. Pankhaniyi, n'zomveka kusankha mankhwala zodzikongoletsera, kumene pH phindu pH adzakhala pafupi ndi mlingo wa 9 - mlingo pazipita alkalinity kuti sadzachititsa kuti makwinya oyambirira, ndipo ziume khungu pang'onopang'ono.

tiyenera kukumbukira kuti mlingo wa zamchere mu alipidwa wotchipa mtanda sopo liri 9-11 14 kufika pamlingo kwa anthu ndi khungu youma. Kugwiritsira ntchito kawirikawiri a sopo pamene youma ndi chivundikiro ndi woyera shelled kukhudza osati nkhope yanu, komanso manja kwambiri Hardy. Anthu oterowo kusamba thovu optimally zofewa ndi zidulo zipatso, kumene index pH atayandikira mlingo 3 (pazipita asidi mlingo). Choncho anthu ngakhale pambuyo kusamba manja adye mafuta chakudya creams.
