Mamwe mapoda ewakisi haangove nekuomesa kwekuvhara uye kuramba kwekukwenya, asiwo ane imwe nhanho yekutsakatika.Semuenzaniso, wakisi yepolypropylene inogona kushandiswa sechinzvimbo chekutsakatika muhupfu husingade mhedzisiro yekutsakatika kwakanyanya.Asi panguva ino, muyero wacho unowanzo pfuura 2%, uye dzimwe nguva pane zviri pachena wax particles kunaya mukunaya.
Mukushandiswa, hupfu hwewakisi huzhinji hunobatanidza, uye kune zvakare nzira mbiri dzekushandisa: pre adding uye post kusanganisa.Wakisi yakazosanganiswa iine upfu hudiki hudiki hudiki hudiki, uye hombe diki wakisi inofanira kusanganiswa nekubuditswa pamwe chete nembishi kuti ishandiswe.
1. Kuwedzera pasi pe1% flakewakisi ye polyethylenekune iyo fomula inogona kuwedzera kugadzirwa uye kuderedza mechanic kupfeka panguva yeextrusion, kunyanya mumamiriro ezvinhu ane zvimwe zvikamu, zvichikonzera mhedzisiro yakakosha.
2. Kuwedzera 0.5-0.8% polyethylene uye amide yakasanganiswa wakisi kune fomula inogona kuvandudza iyo yakaoma hupfu hwemvura uye kuwana kunyange kugovera.
3. Kutsvedzerera, kukwenya kuramba, degassing, kudzivirira mvura, kuenzana, uye kuderedzwa kupenya kwefirimu rekuvhara mushure mekuwedzera.
4. Zvakajairwa wakisi hupfu hunogona kuvandudza kuenzana kwefirimu kana kuwedzera kuzara, asi kune chikamu chekuparara zvichienderana nekusiyana uye kuyerwa.
Kudyidzana pakati pemhando dzakasiyana-siyana dzewakisi kunogona kuvandudza zvakanyanya mechanical properties yefirimu yekuputira, asi panewo mamwe mafungiro asina kunaka mukushanda kunoshanda.Semuyenzaniso, kuwedzera wakisi mudiki muforoma yekudhinda kunobatsira pakubvaruka bepa, uye kuwedzera wakisi yakawandisa kunogona kukonzera kutamisa kusinga jeke kwemavara ekuputira.
Mamwe zvidimbu zvewakisi zvakakora zvinogona kuwedzerwa, zvichiita kuti pave nemakomba asina kudzika kana kukanganiswa kwepazi;Mamwe maamide wax anowedzerwa zvakawandisa, izvo zvinogona kukonzera mhute zviri nyore pamusoro peiyo coating uye kukonzera kurasikirwa kwakanyanya kwekupenya.Nokudaro, mukushandiswa kunoshanda, chekutanga, zvakakosha kunzwisisa maitiro emuviri wezvikamu zvakasiyana-siyana zvemakemikari ehupfu hwewakisi, uye chechipiri, kana wakisi yehupfu inogoverwa, chiyero chinofanira kudzorwa zvakakodzera kusvika pa2%.
