Munyika ine simba rekutongwa kwekudya, kugara pamberi pe curve kwakakosha. KuMeileng, tinodada kutungamira mhosva nekubatanidza evoh (ethylene vinyl doro) zvinhu zvepamusoro mumidziyo yemapurasitiki epurasitiki.
Isina kugadziriswa zvipingamupinyi zvivakwa
Evoh, anozivikanwa nekuda kwehunhu hwakasiyana-siyana hunopesana nemagasi seokisijeni, nitrogen, uye kabhoni dioxide, itsvimbo yemitambo mukudya kwekudya. Kugona kwayo kudzivirira kupinza oksijeni kunochengetedza kutsva chikafu, kunowedzera hupenyu hwesherufu, uye kuchengetedza kutendeka kwekuvimbika. Izvi zvinoita kuti Evoh sarudzo yakakodzera yezvigadzirwa zvakaita kunge mukaka, nyama, uye yakagadzirira-kudya-kudya chikafu.
Ramangwana rinosiririsa
KuMeileng, isu hatisi kungosangana nezvinodiwa zvazvino; Isu tiri zvekugadzira ramangwana. Kutama kwedu kwakananga kune yeVOOH High-BOLY ZVINONYANYA KUTI TINOGONESA KUTI TINOGONESA KUTI VAVANZE UYE NEMAHARA ATYIDHIP. Nekupa mapakeji ari maviri anodzivirira zvakanyanya uye anotsigira, isu tiri kubatsira kune yakasvibirira, indasitiri yekudya chikafu.
Kumbundira pamberi pekutakura kurongedza, maitiro edu ekushandisa Evoh anga ashanduka zvakanyanya. Panzvimbo pekushandisa evoh seyechivira, iye zvino tinoshandisa nzira yekuwedzera co-yekuwedzera inobatanidza evoh ine pe (polyethylene). Iyi nzira inogadzira inoumba zvinhu zvakabatana, kudzokorora, kuisiririsa maitiro ekudzokorora uye kuwedzera kutsigirwa kwezvakatipoteredza kwezvigadzirwa zvedu. Izvi zvakawedzera evoh-pe blend kwete chete chengetedza iyo yakasarudzika isingazivikanwe hunhu hweEVOH asiwo zvinokonzeresa kujaira uye kuchinjika kwe pe. Mhedzisiro yacho ndeyekuisa zvinhu zvinopa dziviriro yepamusoro yezvigadzirwa zvekudya zvichitsigira kuzvitsaurira kwedu mutoro wezvakatipoteredza uye nekutsigira muvhesi yepurasitiki.
Zvishandiso zvinochinja
Yedu evoh-yakavharidzirwa-mapepa ekugadzirisa mhinduro dzinoshamisa. Ivo vanoverengera huwandu hwezvigadzirwa zvekudya, kubva kune zvinwiwa kuti zvipe, uye kuenderana nemafomu akasiyana-siyana ekurongedza - iva mafuro, mabhegi, kana kuputira. Iko kushanduka kweEVOH kwakabatanidzwa neyedu-ye-iyo-iyo-yehunyanzvi yekugadzira inogadzira inotibvumira kusangana nezvinodiwa zvakasiyana zveindasitiri yekudya.
Joinha nesu muRwendo rwedu
Sezvo isu tichiramba tichiongorora uye kuita simprecting mhinduro mukudya kwekudya, tinokukoka kuti ubatane nesu mune rwendo urwu runonakidza. Sarudza Meifeng nekuda kwekuchengetedza, kuchengetedza, uye kunoita, uchiremerwa nzira yeramangwana rakanaka.
