Zvichienderana nekudzika kwakasiyana kwekugadzirwa, pulp yebamboo inogona kukamurwa muzvikamu zvakasiyana-siyana, kunyanya zvinosanganisira Unbleached Pulp, Semi-bleached Pulp, Bleached Pulp neRefined Pulp, nezvimwewo. Unbleached Pulp inozivikanwawo se unbleached pulp.
1. Pulp Isina kucheneswa
Bepa rembanje risina kucheneswa Pulp, inozivikanwawo sepulp risina kucheneswa, rinoreva pulp inowanikwa zvakananga kubva kumhanje kana zvimwe zvinhu zvemiti mushure mekurapwa kwekutanga nemakemikari kana michina, pasina kucheneswa. Rudzi urwu rwepulp runochengetedza ruvara rwechisikigo rwezvinhu zvisina kucheneswa, kazhinji kubva kune yero isina kuchena kusvika kune brown yakasviba, uye ine huwandu hwakawanda hwe lignin nezvimwe zvinhu zvisiri cellulose. Mutengo wekugadzira pulp yemavara echisikigo wakaderera, uye unoshandiswa zvakanyanya muminda isingade kuchena kwakanyanya kwepepa, senge bepa rekurongedza, kadhibhodhi, chikamu chepepa retsika nezvimwewo. Zvakanakira kuchengetedza hunhu hwechisikigo hwezvinhu zvisina kucheneswa, izvo zvinobatsira pakushandiswa kwezviwanikwa nenzira dzinogara kwenguva refu.
2. Pulp Yakacheneswa zvishoma
Pepa re bamboo rakacheneswa zvishoma (semi-bleached bamboo paper Pulp) imhando ye pulp iri pakati pe pulp yechisikigo ne pulp yakacheneswa zvishoma. Rinocheneswa zvishoma, asi mwero wekucheneswa hausi wakanyanya kufanana newe pulp yakacheneswa, saka ruvara rwuri pakati peruvara rwechisikigo neruvara ruchena, uye rinogona kunge richiri neruvara rweyero. Nekudzora huwandu hwe bleach nenguva yekucheneswa panguva yekugadzira pulp yakacheneswa zvishoma, zvinokwanisika kuve nechokwadi chekuti kuchena kwakati ukuwo zvichideredza mari yekugadzira uye kukanganisa nharaunda. Rudzi urwu rwe pulp rwakakodzera zviitiko apo pane zvinodiwa kuti mapepa achene asi kwete kuchena kwakanyanya, senge mamwe marudzi epepa rekunyora, bepa rekudhinda, nezvimwewo.
3. Pulp Yakacheneswa
Mapepa ebamboo akacheneswa akagadzirwa ne bleached pulp, ruvara rwayo rwakafanana neruvara ruchena, ruchena rwakanyanya. Maitiro ekucheneswa anowanzo shandisa nzira dzemakemikari, dzakadai sekushandisa chlorine, hypochlorite, chlorine dioxide kana hydrogen peroxide nezvimwe zvinhu zvinochenesa, kuitira kubvisa lignin nezvimwe zvinhu zvine mavara mu pulp. Mapepa akacheneswa ane kuchena kwakanyanya kwefiber, hunhu hwakanaka hwemuviri uye kugadzikana kwemakemikari, uye ndiyo chinhu chikuru chekugadzira mapepa emhando yepamusoro, mapepa akakosha uye mapepa epamba. Nekuda kwekuchena kwayo kwakanyanya uye kushanda zvakanaka kwekugadzirisa, pulp yakacheneswa ine chinzvimbo chakakosha muindasitiri yemapepa.
4. Pulp yepepa rakanatswa
Refined Pulp inowanzoreva pulp inowanikwa zvichibva pa bleached pulp, iyo inogadziriswazve nenzira dzemuviri kana dzemakemikari kuti ivandudze kuchena uye hunhu hwe fibre ye pulp. Maitiro aya, anogona kusanganisira matanho akadai sekukuya zvakanaka, kuongorora nekusuka, akagadzirirwa kubvisa fibres dzakapfava, tsvina uye makemikari asina kugadzikana kubva mu pulp uye kuita kuti fibres dzipararire uye dzinyorove, nokudaro zvichivandudza kutsetseka, kupenya uye simba repepa. Refined pulp inonyanya kukodzera kugadzirwa kwezvigadzirwa zvepepa zvine kukosha kwakanyanya, zvakaita sepepa rekudhinda repamusoro, bepa reunyanzvi, bepa rakafukidzwa, nezvimwewo, izvo zvine zvinodiwa zvakanyanya kuti bepa rive rakapfava, rifanane uye rigone kuchinjika pakudhinda.
