Mushonga wekudzivirira mvura wepepa
Yakakodzera kugadzirwa kwemapuranga ehuni, reed pulp, kugadzirwa kweAmerican waste pulp yemapepa akasiyana-siyana etsika, bhodhi bepa, newsprint, michero bag bepa uye wrapping bepa nemamwe mapepa, inogona kushandiswa muhuwandu hwakakura hwePH (7-9), mamiriro akakodzera ekugadzira PH (7.5-8.5), inogona kushandisa calcium carbonate filler, Inogona kutsiva saizi yechinyakare yeasidhi yerosin neAKD neutral size. Huwandu hwekuwedzera hwechigadzirwa ichi i0.1-0.15% yeabsolute dry pulp (huwandu hwekuomesa hwechigadzirwa ichi). Paunenge uchishandisa, sanganisa ka5-10 woiisa mu slurry mixing tank woikurunga zvakaenzana.
Papepa rine kuzadza, nzira yekuwedzera ndeyekuisa filler kutanga wozoisa mushonga unodzinga mvura.
Bepa risina kupindirana, wedzera simba repepa, deredza kupararira kwehupfu, kurasikirwa nebvudzi, vandudza kudhindwa. Wedzera kuchengetwa kwefibers dzakapfava nezvimwe zvinowedzera, deredza kushandiswa kwepulp uye kuderedza mitengo. Wedzera mhando yepepa, senge simba repamusoro, kushushikana, kuramba kupeta, saizi, kupenya, kutsvedzerera kwepamusoro nezvimwe zviratidzo zvepepa zviri nani pane zviratidzo zveacid uye zvechinyakare zvesaizi dzisina kupindirana. Rerutsa maitiro esaizi, vandudza mashandiro emuchina wepepa, uye usagadzire chero zvipingamupinyi zvepepa.
Zvigadzirwa zvakafanana: Chinhu chinodzivisa mvura kugadzira mapepa.

Chifukidziro chacho chine dhiramu repurasitiki re200kg uye dhiramu rematani re1000kg. Chigadzirwa ichi chinofanira kuchengetwa muimba ine mhepo inofefetera uye yakaoma kudzivirira
Kuratidzwa kwezuva zvakananga, kutakurwa uye kuchengetwa pa5-35°C, nguva yekuchengetera inoshanda ndeyemwedzi mitatu kubva pazuva rekurongedza.
