Muhupenyu hwedu hwezuva nezuva, makapu emapepa ave chinhu chakajairika. Ingava kofi, tii house kana kuungana kwemhuri, tese tinoshandisa makapu emapepa. Zvisinei, wakambozvibvunza here kuti sei makapu aya emapepa achivimbiswa kuti haazodonhedze mvura? Zvese izvi zvinokonzerwa nekapu yemapepa yakakosha - pepa rakaputirwa nePE.
PE yakafukidzwa nepepa mupumburu ipepa rakagadziriswa rakafukidzwa nefirimu repolyethylene papepa rekutanga. Basa repepa iri nderekusimudzira kushanda kwekapu yepepa isingapindi mvura, uye zvakare kuvandudza kuramba kupisa uye simba rekapu yepepa. Saka, bepa rakaputirwa nePE rinoita sei kuti kapu yepepa isadonhe?
Chekutanga, kusarudzwa kwezvinhu zvepepa rakafukidzwa nePE kwakakosha zvikuru pakushanda kwaro kusina mvura. Firimu rePolyethylene iresini yakagadzirwa ine huremu hwakawanda, ine simba rakanaka rekudzivirira mvura uye inogona kudzivirira hunyoro kuti husapinde mukati mekapu yepepa. Panguva imwe chete, bepa rakafukidzwa nePE rakagadziriswawo zvakanyanya kuti firimu nepepa zvinyatsobatana, zvichidzivirira kupinda kwemvura.
Chechipiri, tekinoroji yekugadzirisa bepa rakaputirwa nePE ine basa guru mukushanda kwaro kwemvura. Munguva yekugadzira, muchina we laminating unopfapfaidza zvakaenzana firimu re polyethylene rakanyungudutswa pabepa repasi kuburikidza nemhepo ine simba guru. Nzira iyi yekugadzira inoumba chisungo chakasimba pakati pebepa nebepa, nokudaro zvichiita kuti bepa rirambe richishanda zvakanaka.
Chekupedzisira, kuti zvionekwe kuti makapu epepa haapindi mvura, kuongorora kwakasimba uye kudzora zvinodiwa panguva yekugadzirisa mafeni ekapu epepa. Semuenzaniso, mipendero yemakapu epepa inofanira kuchekwa nemazvo uye kukuyiwa kuti ive nechokwadi chekuti yakavharwa zvakanaka. Panguva imwe chete, mhando yemakapu epepa inofanira kuongororwa zvisina tsarukano panguva yekugadzira kuitira kuti ive nechokwadi chekuti anosangana nezvinodiwa zvemhando yepamusoro zvakaita sekudzivirira mvura, kudzivirira kupisa, uye simba.
Kuburikidza nehunhu hwayo hwakasiyana hwezvinhu uye maitiro ehunyanzvi ekuputira, bepa rakaputirwa nePE rakabudirira kusimbisa mashandiro ekapu yepepa isingapindi mvura. Kushanda kwayo kusina mvura, kugara kwenguva refu, kuchengetedzeka uye kugona kudzokorodza kunoita kuti bepa rakaputirwa nePE rive sarudzo yakakodzera kushandiswa zvakanyanya mukugadzira makapu epepa.
