Muindasitiri yemapepa, kusarudzwa kwezvinhu zvisina kugadzirwa kwakakosha zvikuru pamhando yezvigadzirwa, mari yekugadzira uye kukanganisa nharaunda. Indasitiri yemapepa ine zvinhu zvakasiyana-siyana, zvinosanganisira pulp yehuni, pulp yebamboo, pulp yehuswa, pulp yehemp, pulp yedonje uye pulp yepepa isina kugadzirwa.
1. Huni dzakagadzirwa nemuti
Pulp yehuni ndeimwe yezvinhu zvinonyanya kushandiswa pakugadzira mapepa, uye inogadzirwa nematanda (mhando dzakasiyana-siyana kusanganisira eucalyptus) kuburikidza nenzira dzemakemikari kana dzemakanika. Pulp yehuni zvichienderana nenzira dzayo dzakasiyana dzepulp, inogona kukamurwa kuita pulp yemakemikari (senge sulphate pulp, sulphite pulp) uye pulp yemakanika (senge grinding stone grinding wood pulp, hot grinding mechanical pulp). Pepa remapulp ehuni rine zvakanakira zvekusimba kwakanyanya, kusimba kwakanaka, kunyudzwa kweinki kwakasimba, nezvimwewo. Inoshandiswa zvakanyanya mukugadzira mabhuku, mapepanhau, mapepa ekurongedza uye mapepa akakosha.
2. Mupunga wemushenjere wemuango
Pulp yemubamboo inogadzirwa nebamboo sechigadzirwa chepulp yepepa. Bamboo ine nguva pfupi yekukura, ine simba rekugadzirazve, imhando yechinhu chisina njodzi pakugadzira mapepa. Pepa remubamboo rine kuchena kwakanyanya, mhepo inoyerera zvakanaka, kuomarara kwakanaka nezvimwe zvinhu, rakakodzera kugadzirwa kwepepa retsika, bepa rehupenyu uye chikamu chepepa rekurongedza. Nekuwedzera kweruzivo rwezvakatipoteredza, kudiwa kwepepa remubamboo kuri kukura pamusika.
3. Pulp yeuswa Pulp yeuswa inogadzirwa kubva mumiti yakasiyana-siyana yemiriwo (yakadai setsanga, wheatgrass, masagasse, nezvimwewo) sezvinhu zvekugadzira. Miti iyi ine zviwanikwa zvakawanda uye inodhura zvishoma, asi maitiro ekupura pulp acho akaoma uye anoda kukunda matambudziko efibre pfupi uye tsvina yakawanda. Pepa repulp yeuswa rinonyanya kushandiswa kugadzira bepa rekurongedza risina kunyanya kunaka, bepa rekugezera nezvimwewo.
4. pulp yehemp
Hemp pulp inogadzirwa neflax, jute nezvimwe zvirimwa zvehemp sezvinhu zvekushandisa pa pulp. Hemp plant fibers dzakareba, dzakasimba, dzakagadzirwa nepepa rehemp rinodzivirira kubvaruka zvakanaka uye rinogara kwenguva refu, rakanyanya kukodzera kugadzirwa kwepepa rekurongedza remhando yepamusoro, bepa remari uye mamwe mapepa eindasitiri akakosha.
5. Donje remupunga
Donje rinogadzirwa nedonje sezvinhu zvinogadzirwa nedonje. Mafaibha edonje akareba, akapfava uye anonwisa inki, zvichiita kuti pepa redonje rive nemagadzirirwo akanaka uye rinyoreke zvakanaka, saka rinowanzoshandiswa kugadzira bepa repamusoro-soro rekunyora nekupenda, bepa reunyanzvi uye mamwe mapepa ane chinangwa chakakosha.
6. Marara eMarara
Sezvinoreva zita racho, marara anogadzirwa nemapepa akadzokororwa, mushure mekubviswa muinki, kucheneswa uye mamwe maitiro ekugadzirisa. Kudzokororwa kwemarara hakungochengetedze zviwanikwa zvechisikigo chete, asiwo kunoderedza kuburitswa kwemarara, inova nzira yakakosha yekuwana budiriro inoenderera mberi yeindasitiri yemapepa. Marara anogona kushandiswa kugadzira marudzi akawanda emapepa, anosanganisira corrugated boxboard, grey board, grey board chena, white bottom white board, newsprint, paper retsika risingakuvadzi zvakatipoteredza, paper reindasitiri rakadzokororwa, uye paper repamba.
