PE Kraft CB, inomiririra Polyethylene Kraft Coated Board, imhando yemidziyo yekurongedza ine polyethylene yekuputira kune rimwe kana mativi ese eKraft board. Uku kupfekedza kunopa yakanakisa hunyoro chipingamupinyi, zvichiita kuti ive chinhu chakanakira kurongedza zvigadzirwa zvakasiyana, kunyanya izvo zvinonzwa kunyorova.
Maitiro ekugadzira ePE Kraft CB anosanganisira akati wandei matanho, anosanganisira:
1. Kugadzirira kweKraft Board: Nhanho yekutanga inosanganisira kugadzirira Kraft board, iyo inogadzirwa kubva pamapuranga emapuranga. Iyo pulp inosanganiswa nemakemikari, akadai sodium hydroxide uye sodium sulfide, uye yobva yabikwa mudigester kubvisa lignin uye kumwe kusvibiswa. Iyo pulp inobuda inogezwa, kucheneswa, uye kukwenenzverwa kugadzira yakasimba, yakatsetseka, uye yakafanana Kraft board.
2. Kuputira nePolyethylene: Kana Kraft board yagadzirwa, yakaputirwa ne polyethylene. Izvi zvinowanzoitwa uchishandisa nzira inonzi extrusion coating. Mukuita uku, polyethylene yakanyungudutswa inodururwa pamusoro peiyo Kraft board, iyo inozotonhodzwa kuti isimbise iyo coating.
3. Kudhinda uye Kupedzisa: Mushure mekuputira, PE Kraft CB inogona kudhindwa nemhando ipi zvayo inodiwa kana zvinyorwa zvichishandisa nzira dzakasiyana-siyana dzekudhinda. Chigadzirwa chakapedzwa chinogona zvakare kutemwa, kupetwa, uye laminated kugadzira tsika yekurongedza mhinduro inosangana nezvinodiwa nevatengi.
4. Kudzora Kwehutano: Mukati yose yekugadzira, matanho akasimba ekugadzirisa maitiro anoshandiswa kuti ave nechokwadi chokuti PE Kraft CB inosangana nezvose zvakakosha uye zvinyorwa. Izvi zvinosanganisira kuyedzwa kwehunyoro kuramba, kunamatira, uye mamwe akakosha maitiro ekuita.
Pakazere, maitiro ekugadzira ePE Kraft CB anodzorwa zvakanyanya uye akajeka, zvichikonzera kurongedza zvinhu zvinogara uye zvakavimbika. Iine yepamusoro-soro inodzivirira hunyoro inodzivirira zvimiro, isarudzo yakanakira kurongedza huwandu hwezvigadzirwa, kubva pachikafu uye zvinwiwa kusvika kune zvemagetsi nemishonga.
