Miti yakagadzirwa nesirivha inogona kuwanikwa munenge misha yese. Iyi simbi inokosha inonyanya kukosheswa nemunhu, uye zvishongo, ndiro, zviyeuchidzo zvakaitwa zvesirivha nguva dzose. Zvinosuruvarisa, chiedza chakajeka chesirivha pamwe nenguva chinotanga kupera, uye zvimwe zvezvinhu izvi zvesimbi zvinosvibira. Ndingaitei uye ndingaitei kuti ndichenese sirivha kumba? Uyu mubvunzo unobvunzwa nevanhu vazhinji vasingadi kuramba vakapfeka mahomwe avo kana kugadzika mumasangano.
Sei sirivha ichichinja?
Zvechokwadi, mumwe nomumwe wedu akabvunza mubvunzo mubvunzo, nei sirivha ikasviba? Sirivha inofungidzirwa sesimbi isingazivikanwi uye hapana mhinduro isina chokwadi kumubvunzo uyu. Sayenzi inotsanangura kusviba kwesirivha semugumisiro wekubatana nesarufa. Iyo yakakosha samuri yesirivha, zvishoma zvichisvibiswa. Vanhu vanoti sirivha inodzoka yakasviba pamuviri, kana munhu ari kurwara kana akaparara. Sirivha yacho inogona kutyisa zvachose kana chikamu chimwe chete. Kazhinji, kune rima resirivha, apo munhu anotora mishonga.
Saka unochenesa sei sirivha?
Icho chinoratidza kuti kuchenesa sirivha inzira yakajeka, iyo munhu wese anogona kuita. Zvechokwadi, hazvidi kuti uende kuchitoro chezvishongo nguva dzose kana iwe uine sirivha. Zviri nyore nyore kuziva aya maitiro akaoma iwe pachako, nokuti pane nzira dzakawanda dzokuchenesa sirivha kumba.
Iva nechokwadi chokuti uwane muenzaniso wechigadzirwa usati wachenesa senivha yesirivha, rin'i kana kuti kiba. Izvi zvinodiwa kuitira kuti sirivha isarasikirwa nezvinhu zvayo:
- yepamusoro-tsvina yekuchenesa kumba, sirivha 625 kana yakakwirira, iwe uchabatsira mhinduro yeammonia;
- yekuchenesa sirivha nemuenzaniso wepasi, mushonga wakanaka ndeye citric acid. Citric acid inofanira kunge yakanyoroveswa nemvura (inenge 1: 3) uye iisepo sirivha yakasviba. Zvinhu zvinofanira kugara zvichishandurwa mumhinduro yekuita yunifomu yekuchenesa. Pashure pemaminitsi makumi maviri nemakumi matatu, chigadzirwa chacho chinofanira kubviswa kubva mugadziro uye kupukunywa chakaoma. Iwe uchaona kuti sirivha yako yakatsva zvakare.
Nzira dzakajeka uye dzisingakwanisi kuchenesa sirivha kumba ndeye bicarbonate sodium - baking soda. "Ndingachenesa sei sirivha nayo?" Iwe unobvunza. Wedzera mvura kune soda musati maumbwa gruel uye gadzirai musanganiswa wezvesirivha kusvikira wava zvakare.
Kana iwe uchida kuchenesa mari yesirivha, zvino munyaya iyi, usashandisa nzira dziri pamusoro apa. Kucheneswa kwemari yesirivha pamusha kunoitwa neasiti. Kana mari yacho yakwegura, zvino mubvunzo unokosha hausi wekuchenesa sirivha chete, asiwo kuti haufaniri kukuvadza sei icho pachako. Kuumbwa kwemari zhinji, kuwedzera kune sirivha, kunosanganisira michina yemhangura. Izvo ndezvekuti ivo sirivha yesirivha inowanzosvibiswa. Ziva kuti rudzi urwu hwekusvibiswa runogona kuva ruvara ruvara. Kuti uchenese mari, inofanirwa kuiisa mumudziyo wegirazi uye kudururira 5% solution ye sulfuric acid. Mari iyo inofanira kubva nguva dzose ichibviswa kubva mumudziyo, yakasvibiswa uye yakaiswazve mune mhinduro. Mushure mokuita izvi nenzira dzinoverengeka, iwe uchadzoka yekare yaipenya kumari.
Kana iyo mari yakawana ruvara rwepepuru, izvi zvinoreva kuti chimiro chesimbi chakavhuniwa. Kuchenesa kumba hakukurudzirwi munyaya ino, kunyanya kana mari iyo inodhura. Zviri nani kutendeukira kumusangano wezvigadzirwa zvemhizha kune unyanzvi. Mushure mokuchenesa imwe chete yesirivha yesimbi, mhete kana ketani kumba, uchaona kuti iri nyore sei, uye kupembera, kunatswa nemaoko ako pachako, kuchawedzerwa zvikuru. Sezvo wanyatsonzwisisa unyanzvi huri nyore, iwe uchaponesa mari pamwe nenguva.
