Kugadzira mapepa kwakatanga muChina yekare, uye matekiniki ayo akavandudzwa uye akafarirwa naCai Lun panguva yeEastern Han Dynasty isati yapararira pasi rose. Kwemazana emakore ekushanduka kwetekinoroji, kugadzira mapepa kwemazuva ano kwave kusimukira kuva sisitimu yekugadzira yakagadzirwa nemaindasitiri uye otomatiki, inobatanidza maitiro akadai se chemical pulping uye mechanical pulping.
Mukugadzira mapepa emazuva ano, kubvisa mvura kubva mupumburu ndeimwe yematanho akakosha zvikuru. Purple yakagadzirwa pakutanga ine mvura yakawanda, uye kubvisa mvura kwakakosha kuti iome inodiwa pakugadzirisa kunotevera. Mapombi evacuum anogadzira mamiriro ekumanikidza asina kunaka kuti abvise mvura yakawandisa kubva mupumburu zvinobudirira, zvichiwedzera zvishoma nezvishoma huwandu hwayo hwakasimba kuti ienderane nezvinodiwa zvehunyanzvi. Izvi hazvingobatsiri chete pakugadzira asi zvinovimbisawo hunhu hwemuviri uye mhando yekupedzisira yepepa.
Zvisinei, panguva yekubvisa mvura, hunyoro, zvidimbu zvefaibha, nezvimwe tsvina zvinotakurwa ne pulp zvinogona kupinda mu vacuum pombi nemhepo. Zvinhu izvi zvinogona kukurumidzisa kupera nekuora kwezvikamu zvikuru zvepombi (zvakadai se rotors, vanes, uye seals), zvichikonzera kudzikira kwehuwandu hwe vacuum, kuwedzera kwesimba rekushandisa, uye kutotadza kushanda kwemidziyo. Kusagadzikana kwekushanda kwe vacuum pombi kunokanganisa zvakananga kushanda zvakanaka kwe dehydration uye kugara zvakanaka kwepepa.
Saka, kugadzirira pombi dze vacuum nemafirita egasi-mvurazvakakosha. Mafirita egasi-mvura anobata hunyoro, guruva refaibha, uye zvidimbu zvidiki, zvichidzivirira kupinda mupombi. Izvi zvinopa mabhenefiti akakosha akati wandei:
- Kudzivirirwa kwezvikamu zvepakati, zvichiwedzera hupenyu hwebasa repombi ye vacuum;
- Kugadziriswa kwemazinga evacuum akasimba uye kumhanya kwekupomba, kuve nechokwadi chekuti mvura inobviswa nguva dzose;
- Kuderedzwa kwemitengo yekukundikana uye mari yekugadzirisa, zvichiwedzera kuvimbika kwesystem;
- Hunhu hwepepa hunogara huripo, zvichideredza kusiyana kwekugadzirwa uye marara.
Muchidimbu, mukubvisa mvura muindasitiri yekugadzira mapepa, basa rekubatana kwemapombi evacuum nemafirita rakakosha kwete chete pakushanda kwemidziyo yega yega asiwo pakushanda zvakanaka, kugadzikana, uye kushanda zvakanaka kwehurongwa hwese hwekugadzira. Kusarudzwa kwakakodzera, kuiswa, uye kugadziriswa nguva dzose kwemafirita epombi ye vacuummatanho akakosha kumabhizinesi ane chinangwa chekuvandudza mhando, kuwedzera kushanda zvakanaka, uye kuwana budiriro inoenderera mberi.
