Q: Kodi mankhwala ofewetsa madzi ndi chiyani?

A:

M'moyo watsiku ndi tsiku, nthawi zambiri timawona masikelo akupanga pakhoma lamkati la ketulo atagwiritsidwa ntchito kwa nthawi yayitali. Zinapezeka kuti madzi omwe timagwiritsa ntchito amakhala ndi mchere wambiri, monga calcium ndi magnesium salt. Mcherewu sungakhoze kuwonedwa ndi maso amaliseche m'madzi otentha kutentha. Akatenthedwa ndi kuwiritsa, mchere wambiri wa calcium ndi magnesium umatuluka ngati carbonates, ndipo amamatira ku khoma la mphika kuti apange masikelo.

Kodi madzi ofewa ndi chiyani?

Madzi ofewa amatanthauza madzi omwe alibe calcium kapena ma magnesium osungunuka. Madzi ofewa sangavute ndi sopo, pomwe madzi olimba ndi osiyana. Madzi ofewa achilengedwe nthawi zambiri amatanthauza madzi a mitsinje, madzi a mitsinje, ndi madzi a m'nyanja (nyanja yamchere). Madzi olimba ofewetsedwa amatanthauza madzi ofewa omwe amapezeka mchere wa calcium ndi magnesiamu wachepetsedwa kukhala 1.0 mpaka 50 mg/L. Ngakhale kuwiritsa kumatha kusintha madzi olimba kwakanthawi kukhala madzi ofewa, ndizopanda ndalama kugwiritsa ntchito njirayi kuti athetse madzi ambiri m'makampani.

Kodi kusungunula madzi ndi chiyani?

Mphamvu ya acidic cationic resin imagwiritsidwa ntchito m'malo mwa ma ion calcium ndi magnesium m'madzi osaphika, kenako madzi opangira boiler amasefedwa ndi zida zofewa zamadzi, potero amakhala madzi oyeretsedwa a ma boiler okhala ndi kuuma kotsika kwambiri.

Nthawi zambiri timafotokozera zomwe zili mu calcium ndi magnesium ions m'madzi monga "kuuma". Digiri imodzi ya kuuma ndi yofanana ndi mamiligalamu 10 a calcium oxide pa lita imodzi ya madzi. Madzi omwe ali pansi pa madigiri 8 amatchedwa madzi ofewa, madzi pamwamba pa madigiri 17 amatchedwa madzi olimba, ndipo madzi apakati pa 8 ndi 17 madigiri amatchedwa madzi olimba. Mvula, chipale chofewa, mitsinje, ndi nyanja zonse ndi madzi ofewa, pamene madzi akasupe, zitsime zakuya, ndi madzi a m’nyanja zonsezo ndi madzi olimba.

Ubwino wa madzi ofewa

1. Kupulumutsa mphamvu, kuteteza chilengedwe, kukulitsa moyo wautumiki wa zida zapamadzi
Popereka madzi a m'mapaipi a m'tawuni, titha kugwiritsa ntchito chofewetsa madzi, chomwe chingagwiritsidwe ntchito nthawi zonse chaka chonse. Sizimangowonjezera moyo wautumiki wa zida zamadzi okhudzana ndi madzi monga makina ochapira nthawi zopitilira 2, komanso zimapulumutsa pafupifupi 60-70% ya zida ndi mtengo wokonza mapaipi.

2. Kukongola ndi kusamalira khungu
Madzi ofewa amatha kuchotseratu litsiro pama cell a nkhope, kuchedwetsa kukalamba kwa khungu, ndikupangitsa khungu kukhala losalimba komanso lonyezimira pambuyo poyeretsa. Popeza kuti madzi ofewa amakhala ndi zotsekemera zolimba, zodzikongoletsera zochepa zokha zimatha kukwaniritsa 100% zochotsa zodzoladzola. Choncho, madzi ofewa ndi ofunikira m'moyo wa okonda kukongola.

3. Tsukani zipatso ndi ndiwo zamasamba
1. Gwiritsani ntchito madzi ofewa kutsuka zosakaniza zakukhitchini kuti muwonjezere moyo wa alumali wamasamba ndikusunga kukoma kwawo ndi fungo lawo;
2. Kufupikitsa nthawi yophika, mpunga wophika udzakhala wofewa komanso wosalala, ndipo pasitala sudzatupa;
3. Zitsulo za tebulo zimakhala zoyera komanso zopanda madzi, ndipo kuwala kwa ziwiya kumakhala bwino;
4. Pewani magetsi osasunthika, kusinthika ndi kusintha kwa zovala ndikupulumutsa 80% ya zotsukira;
5. Wonjezerani nthawi ya maluwa, popanda mawanga pa masamba obiriwira ndi maluwa okongola.

4. Zovala za unamwino
Zovala zochapira zamadzi zofewa ndi zofewa, zoyera, ndipo mtundu wake ndi watsopano. Ulusi wa zovala umachulukitsa kuchuluka kwa zochapira ndi 50%, umachepetsa kugwiritsa ntchito ufa wochapira ndi 70%, komanso umachepetsa zovuta zosamalira zomwe zimachitika chifukwa chogwiritsa ntchito madzi olimba pamakina ochapira ndi zida zina zogwiritsira ntchito madzi.
