Semusanganiswa wekongiri, mvura inoderedza mumiriri inoita basa rakakosha mukuvandudza kuita kwekongiri.Mvura inoderedza mumiriri musanganiswa unogona kuderedza zvakanyanya kusanganisa kushandiswa kwemvura uchichengeta dhigirii rekushanda resimende paste, dhaka uye kongiri isina kuchinjika.Impermeability kana kuderedzwa simende dosage.Uyu muenzaniso unopa nzira yekushandisa tsvinaPET plastikikugadzira mvura inodzikisa agent, inogona kudzoreredza tsvinaPET plastiki, kuderedza kusvibiswa, kuderedza mutengo wekugadzirwa kwemvura inoderedza mumiririri.
Pet-based polyester zvinhu hazviparare, uye zvine mukana wekuve zvakare, kubvisa kudiwa kwekushandisa zvakare terephthalic acid uye ethylene glycol yekupolymerization.Nekudaro, iyo tekinoroji yekugadzirisa uye kudzokorodza tekinoroji yePET zvinhuzvichiri kuda kuvandudzwa nekunatswa.Polyester ndicho chinhu chikuru chemicheka yakarukwa isina kuruka, inogona kushandiswa pa260 ° C kwenguva yakareba.Iwo akarukwa uye anopisa-akatenderedzwa machira asiri akarukwa akagadzirwa kubva mumarara PET anogona kuderedza mutengo wekugadzira wemabhizinesi.Nekushandisa zvizere maitiro ezvakagadzirwazvepolyester zvinhu, Izvo simba zvimiro zvepolyester spunbonded uye inopisa-yakakungurutswa isina-yakarukwa machira anowedzerwa kuvandudzwa kuburikidza nekugadzirisa maitiro.
