Muhupenyu hwedu hwezuva nezuva, makapu emapepa ave chinhu chakajairika.Kunyangwe iri chitoro chekofi, imba yetii kana kuungana kwemhuri, tese tinoshandisa makapu emapepa.Nekudaro, wakambozvibvunza here kuti sei aya makapu emapepa akavimbiswa kusadonha?Zvese izvi zvinokonzerwa nekiyi yekapu kapu mbishi zvinhu - PE yakavharwa bepa.
PE yakavharwa pepa rollchigadzirwa chepepa chakagadziriswa chakafukidzwa nejira re polyethylene firimu pane base bepa.Basa reiyi firimu nderekusimudzira kushanda kwemvura yemukombe wepepa, uye zvakare kugadzirisa kupisa kwekudzivirira uye kusimba kwekapu yepepa.Saka, PE yakavharwa bepa inoita sei kuti mukombe wepepa haubvire?
Chekutanga pane zvese, kusarudzwa kwezvinhu zvePE coated paper kwakakosha pakuita kwayo kusapinda mvura.Firimu repolyethylene iresin yekugadzira ine huremu hwemamorekuru, ine kuita kwakanakisa kusapinda kwemvura uye inogona kudzivirira hunyoro kubva mukati memukombe wepepa.Panguva imwecheteyo, PE yakavharwa bepa yakave yakanyatso kubatwa kuita musanganiswa pakati pefirimu nebepa zvakanyanya kusimba, nekudaro kudzivirira kupinda kwemvura.
Kechipiri, iyo tekinoroji yekugadzirisa yePE yakavharwa bepa zvakare inoita basa rakakosha mukuita kwayo kusapinda mvura.Munguva yekugadzira, muchina welaminating unomwaya zvakaenzana firimu repolyethylene rakanyungudutswa pabepa repasi kuburikidza nemhepo inodzvanywa.Iyi nzira yekugadzira inoumba chisungo chakasimba pakati pefirimu nepepa, nekudaro kuve nechokwadi chekushanda kwemvura yemukombe wepepa.
Pakupedzisira, kuitira kuti uwedzere kuve nechokwadi kuti makapu emapepa haana mvura, kuongorora kwakasimba uye kutonga kunodiwa panguva yekugadziriswa kwemafeni emukombe wepepa.Semuenzaniso, mipendero yemapepa emakapu inoda kunyatsochekwa uye pasi kuti ive nechokwadi chekuisa chisimbiso chakanaka.Panguva imwecheteyo, kunaka kwekapu dzemapepa kunoda kuongororwa zvisina tsarukano panguva yekugadzira kuti ive nechokwadi chekuti inosangana nemhando dzemhando dzakadai sekudzivirira kwemvura, kupisa kupisa, uye simba.
Kuburikidza neayo akasarudzika maitiro uye nehunyanzvi hwekubatisa maitiro, PE yakavharwa bepa yakabudirira kuvimbisa kusapinda mvura kwekapu yepepa.Kuita kwayo kusapinda mvura, kusimba, kuchengetedzeka uye kudzokorodza kunoita kuti PE yakavharwa bepa ive sarudzo yakanakira kushandiswa zvakanyanya mukugadzira kapu yemapepa.
