Muchina wekuwedzera: kutumira chiedza, hunhu uye mashandisirwo emapolymers akajeka

Kubva pamabhodhoro emukaka, kusvika kumalenzi emaziso, kusvika kumaTV kana mafoni …… runyorwa rwemashandisirwo emapurasitiki anoonekera haruperi. Nhasi, takakomberedzwa nemhando dzakawanda dzepurasitiki dzinoonekera kana dzakagadziriswa zvakajeka dzinoita kuti zvigadzirwa zvive zvinokwezva uye zvinotakurika kupfuura magirazi echinyakare.
Iye zvino, vagadziri vakati wandei vari kushandisa kunaka uye kuenderana kwemavara epurasitiki inoonekera pakushandisa kwakasiyana-siyana:
1. kugadzira zvigadzirwa zvakareruka, zvinogara kwenguva refu uye zvisingaputsike;
2. Kuderedzwa kwemari yekugadzira;
3. kugadzirwa kwejometri dzakaoma uye zvikamu zvakaumbwa zvakasiyana;
4. Inowana mukana wekuburitsa zvinhu zvinoonekwa uye/kana kuti optical refractive index yakafanana neyegirazi
Zvichingoenda zvakadaro…

Dzimwe nzvimbo dzakakurumbira dzekushandisa dzinobatsirwa nemabhenefiti ari pamusoro apa ndedzinotevera:

1. Kurongedza (zvekudya, zvekuzora ……)
2. Zvigadzirwa zvevatengi (magaba ezvekudya, zvigadzirwa zvekuchengetedza data, magirazi ……)
