Ruzivo rweChigadzirwa:

Kupenya kwemazisotekinoroji yekucheneswa kwemuviri inoshandiswa zvakanyanya mumaindasitiri emazuva ano, uyeVamiririri veOptical Brightener(OBAs) dzinoshanda semakemikari makuru anoshanda kuti zviitike. Dzinonziwo fluorescent whitening agents, idzi organic compounds dzave zvinhu zvinonyanya kukosha mumachira, kugadzira mapepa, sipo, mapurasitiki uye machira, nekuda kwehunhu hwadzo hwekuona uye kushanda kwadzo kwakavimbika.

Zvimiro:

1. Upfu hweyero.
2. Yekupenya donje, mvere dzemakwai, sirika, uye pulp.
3.Muyero wepamusoro wesarudzo dzakasiyana dzekurongedza.
4.Bepa rakajeka uye rakasimba, ruvara rwemachira edonje.

Kushandiswa:

Nemhando dzakasiyana-siyana dziri pamusika, mishonga yakasiyana-siyana yechiedza inogadzirwa kuti ikwane zvinhu zvakagadziriswa uye nzvimbo dzekugadzira. Pakati payo, Optical Brightener Agent BBU inoonekwa sechigadzirwa chemhando ye stilbene tetrasulfonic acid, icho chinozivikanwa zvikuru mumaindasitiri emachira nemapepa pasi rese. Panyaya yemakemikari, inyanzvi yekuchenesa inonyungudika mumvura ine hunhu hwakanaka. Ine kunyungudika kwakanaka mumvura: inenge magiramu zana nemakumi mashanu (150 grams) inogona kunyungudika mu litre imwe yemvura inotonhora, uye kunyungudika kunokwira kusvika magiramu mazana matatu (300 grams) pa litre mumvura iri kufashaira. Kunze kweizvozvo, BBU inoratidza kushivirira kwakasimba kumvura yakaoma; calcium ne magnesium ions mumvura hazvikanganisi mashandiro ayo ekuchena. Inewo kuenderana kwakanaka nemidziyo yekuchenesa yakajairika uye mishonga yekuderedza inoshandiswa mukugadzira. Kana iri mamiriro ekushandiswa, inopa mhedzisiro yakanaka yekuchena munzvimbo dzine alkaline ine pH iri pamusoro pe7, nepo kuramba kwayo acid kuri pakati nepakati, saka haikurudzirwi kune zviitiko zvekugadzirisa acid zvakanyanya.
