Kutarisa kana ph pakusarudza chigadzirwa zvizorwa?

Zvimwe dzawakambonzwa zvokushambadza uye sipo yokugezera gels, kutsenga matadza, uye, kashoma, mumakenduru, asinganzwisisiki shoko "Paix Ash." Chii uye sei zviri kukosha kwatiri pakusarudza detergents uye zvizoro? Ngatitarisei seizvi, kuti arege buda kupinda namakemikari "kwemasango." Rn mu Latin - "pundus hydrogenium" - rinoreva "uremu rehydrogen." Izvi ph ukoshi chinoratidza pachiyero alkali pamberi chero mhinduro kana hwakasimba. Uyewo ari kushambadza vanoshandisa mubatanidzwa asidhi-pechingoro mwero uye munhu kwazvakarerekera ph.

"Soap unoomesa ganda ..." - ndiro shoko guru dzinodhura okushambadza yokugezera gel. Zvechokwadi, alkali - huru pazvokudya detergents - ane zvakadaro zvakaitika. Zvisinei, kurega zvachose kuti alkali Uyewo zvisingaiti, nokuti aiva mubatsiri wake shambidza tsvina. Pasina nesipo sipo - chero sipo, ndiko, kuisa mutauro Vhangeri anova munyu kuti varasikirwa salinity wayo. Saka ph mutengo anoratidza sei nesipo zvikuru zviri chigadzirwa ichi. Rangarirai chikoro nesayenzi: kuti nesipo chisisimo? Ndizvozvo, asi acid. Naizvozvo, isu kudzima kubikira pasoda uye vhiniga. Izvi zviviri zvinhu zvinokuvadza ari yakaisvonaka chimiro, vose vane nezvakwakaipira kukanganisa ganda: corrodes asidhi uye alkali Dries.

The ph chakarurama inogona kufungwa somunhu kwakaita razero kusvika 14. Kana ph akaenzana razero, zvinoreva kuti hapana alkali iri - asidhi wakachena chimiro. Kana ari gumi - dzinongoitika alkaline. In kwakadonhera mvura, naizvozvo, kuti ph akaenzana nomwe. Pakutanga zvinoita sokuti nomwe - ndiyo yakanakisisa chinoratidza asidhi-hwaro mwero. Asi kwete - mvura iri zvakare aome ganda, uye ari kunyanya zvakanaka vainzwa nevaya, shure dzinoshambira refu kana achigeza anonzwa ane pakafunuka kumusana kwake. Sei tinowana "pakati pasi", kuti arege kunzwa zvinokonzerwa asidhi kana alkali chaiyo iri pachavo ganda ravo?

Ganda redu anewo yayo ph ukoshi. It yemakomo mukati mana nehafu (mu vanhu vane jikichira ganda) kusvika mashanu nehafu (yakaoma ganda). Saka, mashoko akanyorwa sipo, ruomba kana gel kuti yokugezera "mwero ph" zvinoreva kuti ari chigadzirwa rehydrogen pamwero haasi kupfuura 4.5-5.0 14-pfungwa dzakawanda. chinhu Same mu nokushambadzira bhabhurigamu: mumwe chikonzero kutsenga navo - zviri anokurumidza kudzosa asidhi-alkaline pakuenzanisa muromo pashure vachidya nokunwa. Asi chii anoita pakushambwa? Kubviswa ichi tsvina ganda akafa nezvimedu uye panguva imwecheteyo rokumusoro ganda rukoko (chii chinonzi peeling kushanda). The sebaceous mumasero secrete chinhu acidic mafuta iyo yabviswa uye kwete kupfuura alkali.

Naizvozvo, kana achisarudza Sipo nezvimwe detergents, munhu anofanira kufunga zvakadini uchida kubvisa urwu runodzivirira iine acid kamafurashi nejasi. Mushure asidhi kunodzivisa kurasikirwa nemvura, asi kunodzivirira chapping, ultraviolet mwaranzi, zvinokonzerwa kwezvakatipoteredza. Chimwe chinhu, kana sebaceous mumasero - somuenzaniso, munguva pabonde kuibvisa - kubereka mafuta akawandisa. Zvadaro, pores kuva tsinga, zvichiita kuti chitarisiko ouduku mburwa uye mburwa. Muchiitiko chino, zvine musoro kuti kusarudza zvizorwa zvigadzirwa, apo ph ukoshi ph achava pedyo chiratidzo 9 - kufadza nenhanho alkalinity kuchaita kuti kukuita kuti mangwanani wrinkles, uye huchaoma ganda zvinyoronyoro.

zvinofanira kuyeukwa kuti padanho alkaline senguva dzose zvakachipa mukanyiwa sipo vakaenzana 9-11 14-nguva pamwero vanhu vane ganda rakaoma. kushandiswa kwakadaro kakawanda sipo kana chakaoma uye kufukidza pamwe chena shelled musabata chete wenyu chiso, asi maoko zvikuru akaomarara. Nokuti vanhu vakadaro kusuka optimally nyoro furo nemichero acids, apo indekisi ph pedyo sandara 3 (kufadza iine acid pamwero). vanhu vakadaro kunyange pashure maoko vanofanira kudya mafuta zvinogutsa mumakenduru.
