N'chifukwa chiyani makapu amadzi osavuta ayamba kukhala ovuta?

Pamsika panali kapu yabwino yamadzi yomwe idapindidwa mwathupi. Sanapangidwe ngati kapu yamadzi ya silikoni. Kapu yamadzi yopindika ngati iyi idawoneka nthawi zambiri m'ndege ngati mphatso yaying'ono kwa apaulendo. Kale zidabweretsa kumasuka kwa anthu, koma m'kupita kwa nthawi, kuwongolera kwaukadaulo, kusintha kwa magwiritsidwe ntchito ndi zotsatira zake, kapu yamadzi iyi yopindika komanso yabwino yayamba kupezeka pamsika. Chifukwa chake ndikuti kapu yabwino yamadzi yakhala yovuta. Chifukwa chiyani?

M'zaka za m'ma 1920, madzi amchere asanatulutsidwe, anthu ankanyamula mabotolo amadzi poyenda. Kapu yamadzi yotereyi makamaka ndi chikho chamadzi cha enamel chopangidwa ndi tinplate, chomwe chimakhala chovuta kunyamula. Pofuna kuti zikhale zosavuta kuti anthu azinyamula pamene akuyenda kutali, ndipo panthawi imodzimodziyo apange chikho chamadzi chopepuka komanso chotsika mtengo, kapu yamadzi yopindika komanso yabwino idabadwa. Kapu yamadzi imeneyi inali yotchuka kale pamsika. Pamene ena akugwiritsa ntchito mabotolo amadzi ochuluka, botolo lamadzi laling'ono, lopepuka lokhala ndi ntchito yopinda mwamatsenga lidzakopa maso osawerengeka. Komabe, popeza ambiri mwa botolo la madziwa amapangidwa ndi pulasitiki, amapezeka kuti amawonongeka mosavuta akagwiritsidwa ntchito. Panthawi imodzimodziyo, mavuto opangira ntchito adayambitsa kugwiritsa ntchito mosasamala komanso kusindikiza kwautali, zomwe zinachititsa kuti malonda achepetse.

Ndi kupanga madzi amchere komanso kuchuluka kwa ndalama za anthu, anthu amakonda kugula botolo la madzi amchere akakhala ndi ludzu. Pambuyo pakumwa, botolo likhoza kutayidwa nthawi iliyonse, zomwe sizingasokoneze anthu ponyamula. Ndi chifukwa cha kutuluka kwa madzi amchere kuti chiwerengero cha operekera madzi m'malo opezeka anthu ambiri chayamba kuchepa. Kapu yamadzi yamtunduwu imakhala ndi ntchito yochepa. Mukagwiritsidwa ntchito, kapu yamadzi yopindika idzauma, kuchotsedwa kuti igwiritsidwe ntchito kapena kukhala yodetsedwa chifukwa chosasungidwa bwino. Pamafunika kuyeretsa musanagwiritse ntchito, ndi zina zotere. Kapu yamadzi yoyambira yabwino yapatsa anthu kumverera kovutirapo. Ngakhale mtengo wake ndi wotsika, umachotsedwa pang'onopang'ono ndi msika.

M’zaka zaposachedwapa, popita ku zionetsero, taona makapu akupinda madzi opangidwa ndi zitsulo zosapanga dzimbiri. Kuwonjezera pa kukhala wokulirapo, pamene apinda, m’mphepete mwazitsulo zosapanga dzimbiri amatha kuvulaza anthu ngati sanayeretsedwe. Pambuyo pake, ndinazindikira kuti makapu amadzi osapangapanga oterowo samawonekeranso pamsika.
