Midziyo yekutamba yevana yakakosha pakukura kwevana uye kuvaraidzwa kwavo. Pakati pezvinhu zvakawanda zvinoshandiswa pakugadzira midziyo yekutamba, machira ePE (polyethylene) ave sarudzo inofarirwa nekuda kwezvakanaka zvavo zvakasiyana. Saka sei machira ePE achisarudzwa pakugadzira midziyo yekutamba yevana? Chinyorwa chino chichakuzivisai nezveMapepa eHDPE.
Sheti yeHDPE ine ganda rakachekwa, inozivikanwawo sepeel yeorenji yeHDPE, isarudzo yakanaka yemidziyo yekuvaraidza. Nzvimbo ine ganda rakachekwa haina chete hunhu hwakanaka hwekudzivirira kutsvedza asiwo inoderedza kuneta kunokonzerwa nekutamba kwenguva refu.
Pepa rakagadzirwa nechando reHDPE, rinozivikanwawo seganda reorenjiPepa reHDPE, isarudzo yakanaka yemidziyo yekuvaraidza. Nzvimbo ine chando haina chete hunhu hwakanaka hwekudzivirira kutsvedza asiwo inoderedza kuneta kunokonzerwa nekutamba kwenguva refu.
Mapuranga aya ane mavara akajeka uye ane chimiro chakasiyana anogadzira nzvimbo inonakidza uye inonakidza yekutamba yevana. Hunhu hwemachira aya hunodzivirira kupera, hunodzivirira ngura, hunodzivirira kutonhora, hunodzivirira kupisa kwakanyanya, uye hunodzivirira UV hunoita kuti puranga idzi dzikwanise kutsungirira mhepo, zuva, mvura, uye sinou kunyangwe panze, zvichiramba kwenguva refu.
Uyezve, machira eHDPE akaomeswa nechando akachengeteka uye haakuvadzi nharaunda.Mapepa eHDPEMidziyo yekutambira mitambo haina chete nzvimbo yekutambira yakachengeteka uye yakasununguka asiwo inobatsira mukusimudzira nharaunda yepasi. Iyi midziyo haina chepfu, haina hwema, haina kusvibiswa, uye inogona kudzokororwa, ichienderana nepfungwa dzemazuva ano dzekuchengetedza nharaunda dzakasvibira. Iyi midziyo inoshanda uye ine runako ichaunza kushamisika uye kunakidza kuhudiki hwevana.
