Pakutenga amburera, vatengi vanogara vachivhura amburera kuti vaone kana mukati mayo muine "sirivheri" kana kuti "sirivheri" mukati. Pakunzwisisa kwedu, tinogara tichifunga kuti "sirivheri" inofanana ne "anti-UV". Icharamba UV zvechokwadi here?
Saka, chii chaizvo chinonzi "guruu resirivha"?
Guruu resirivha iguruu, rinonyanya kushandiswa kufukidza, kwete kudzivirira UV
Zvichienderana neukobvu hwejira, rinogona kukamurwa kuita sirivha yekutanga, sirivha yechipiri, sirivha yakapetwa katatu, sirivha yakapetwa kana kana, kana zvikamu zvakawanda zvakaputirwa, zvichiratidza mhedzisiro iri nani yemumvuri, mhedzisiro yemumvuri inonzwa zvakanaka pachena kuti inotonhorera, pamusoro peglue resirivha, kune amburera ye "glue yemavara" yazvino uye "glue dema", mhedzisiro yekudzivirira chiedza yakanakawo.
Kutaura zvazviri, chinangwa cheamburera ine rabha yesirivha mumumvuri, pane kudzivirira UV, asiwo nekuti kupinda kweUV-B kuchava kusina simba, pane amburera yakawanda yekudzivirira muviri, mhedzisiro imwechete ndeyekudzivirira kupiswa nezuva.
Asi kutaura chokwadi, hazvikurudzirwi kushandisa amburera dzine guruu resirivha, nekuda kwezvikonzero zviviri.
1. Guruu resirivha ipurasitiki yemakemikari, kana iri guruu resirivha rakanaka, rine vimbiso yemhando yepamusoro, asi amburera dzakachipa dzinoderedza mitengo, guruu resirivha rinopendwa kuti ritaridzike zvakanaka pasina, zvinonetsa ndezvekuti pamwe muzuva zviri nyore kupa zvinhu zvakaipa kumuviri wemunhu, kana pasina nzira yekusimbisa guruu resirivha rakanaka nerakaipa, edza kudzivirira kushandisa guruu iri.
2. Rutivi rwemukati rweamburera ine rabha yesirivha, rucharatidza kudzorwa kwepasi kwemwaranzi yerenji refu, sezvo mhedzisiro yegreenhouse yekudzokorora kusingaperi, kupisa kunobatanidzwa, uye kunogona kutomisa kupisa kwakasviba!
Saka, semutengesi weamburera ane hunyanzvi, tinoshandisa pendi yeUV yemhando yepamusoro chete pamaamburera edu. Hapana makemikari achabuda kubva mumaamburera edu. Uyezve, pendi nhema ndiyo sarudzo iri nani.
