Muindasitiri yemapepa, kusarudzwa kwezvinhu zvakabikwa kwakakosha kune mhando yechigadzirwa, mutengo wekugadzira uye kukanganisa kwezvakatipoteredza. Indasitiri yemapepa ine zvakasiyana siyana zvekushandisa, kunyanya zvinosanganisira pulp yehuni, bamboo pulp, uswa pulp, hemp pulp, donje pulp uye tsvina pepa pulp.
1. Tsvina yehuni
Huni pulp ndechimwe chezvinhu zvakajairika zvekugadzira mapepa, uye inogadzirwa kubva muhuni (marudzi akasiyana-siyana anosanganisira eucalyptus) kuburikidza nemakemikari kana mechanical nzira. Pulp yehuni zvinoenderana neyakasiyana nzira dzekupuruzira, inogona kukamurwazve kuita kemikari pulp (senge sulphate pulp, sulphite pulp) uye mechaniki pulp (sekukuya ibwe kukuya huni, inopisa kugaya mechanic pulp). Wood pulp bepa rine zvakanakira simba rakakwirira, kusimba kwakanaka, kunyura kwakasimba inki, etc. Inoshandiswa zvakanyanya mukugadzirwa kwemabhuku, mapepanhau, pepa rekurongedza uye pepa rinokosha.
2. Bamboo pulp
Bamboo pulp inogadzirwa kubva mushenjere seyakagadzirwa mbishi dzemapepa. Bamboo ine kupfupika kwekukura kutenderera, yakasimba regenerative kugona, ishamwari yezvakatipoteredza mbishi yekugadzira mapepa. Bamboo pulp paper ine kuchena kwepamusoro, kunaka kwemhepo, kuoma kwakanaka uye humwe hunhu, hwakakodzera kugadzirwa kwebepa retsika, bepa rekugara uye chikamu chemapepa ekurongedza. Nekuvandudzwa kwekuziva kwezvakatipoteredza, kudiwa kwemusika kwe bamboo pulp bepa kuri kukura.
3. Grass pulp Grass pulp inogadzirwa kubva kune zvakasiyana-siyana zvinomera zvinomera (zvakadai setsanga, wheatgrass, bagasse, etc.) sezvigadzirwa. Izvi zvinomera zvakapfuma mune zviwanikwa uye mutengo wakaderera, asi iyo pulping process yakaoma uye inoda kukurira matambudziko epfupi fiber uye kusvibiswa kwakanyanya. Grass pulp bepa rinonyanya kushandiswa kugadzira yakaderera-giredhi yekurongedza bepa, pepa rechimbuzi uye zvichingodaro.
4. hemp pulp
Hemp pulp inogadzirwa neflax, jute uye zvimwe zvidyarwa zvehemp semidziyo yemafuta. Hemp chirimwa mafibhi akareba, akasimba, akagadzirwa nehemp bepa ane yakanaka kubvarura kuramba uye kusimba, kunyanya akakodzera kugadzirwa kwepamusoro-giredhi rekurongedza mapepa, pepa rebhengi uye mamwe akakosha maindasitiri mapepa.
5. Cotton pulp
Cotton pulp inogadzirwa kubva mudonje seyakagadziriswa ye pulp. Cotton fibers yakareba, yakapfava uye ink-absorbent, ichipa pepa rekotoni pulp chimiro chepamusoro uye kushanda kwekunyora, saka inowanzoshandiswa kugadzira high-grade calligraphy uye pepa rekupenda, pepa remifananidzo uye mamwe mapepa ane chinangwa chakakosha.
6. Waste Pulp
Waste pulp, sezita rinoratidza, inogadzirwa kubva pabepa remarara, mushure mekuita deinking, kucheneswa uye mamwe maitiro ekurapa. Kudzokororwa kwemarara marara hakungochengetedze zviwanikwa chete, asi zvakare kunoderedza kuburitswa kwemarara, inova nzira yakakosha yekuwana budiriro yakadzikama yeindasitiri yemapepa. Waste pulp inogona kushandiswa kugadzira akawanda marudzi emapepa, anosanganisira corrugated boxboard, grey board, grey pasi chena bhodhi, chena pazasi chena bhodhi, newsprint, kwezvakatipoteredza tsika bepa, recycled indasitiri mapepa, uye imba mapepa.
