Mumakore achangopfuura, vanogadzira mapepa uye vashandisi vakabhadhara zvakanyanya uye zvakanyanya kutarisisa kuwanda kwemapepa, nekuti vhoriyamu ine simba rakakura pamutengo uye kushanda kwechigadzirwa.Yakakwira yakawanda density inoreva kuti pakukora kwakafanana, huremu hunogona kudzikiswa uye huwandu hwefiber hunoshandiswa hunogona kudzikiswa, kuitira kuti uwane chinangwa chekuchengetedza mari;hukuru hukuru hunogona kuwedzera kuoma kwepepa, zvichibvumira vaparidzi vebhuku kuchengetedza mabhuku akazara ane mapeji mashoma Ukobvu hunogonawo kuwedzera kupenya kwepepa, kudhindwa uye kuderedza kubuda kweingi yekudhinda.Naizvozvo, Takamatsu ine kukosha kukuru kukudzora mutengo webepa, kuita kwechigadzirwa uye chigadzirwa chakawedzerwa kukosha.
Chii chinonzi inzwi repamusoro?Iyi indekisi yakakosha yepepa, ndiko kuti, reshiyo yehuremu hwehwaro kune ukobvu.Inzwi rinomiririra kuwanda kwepepa, ndiko kuti, ukuru hweporosity yepepa.
Zvinhu zvikuru zvinokanganisa huwandu hwepepa zvinosanganisira bepa fiber raw material, pulp rudzi, kurova mashandiro, filler, makemikari, kudzvanya, kuomesa, calendering, nezvimwe.
Iyo fiber morphology yepapermaking fiber raw material ine yakakosha pesvedzero pakuwanda kwehuwandu hwebepa.Mafiibha akakora ane porosity yakakwira uye yakakwira yakawanda density yemapepa, asi kuwanda kwehuwandu hakunei nefiber ukobvu chete, asiwo kune hukama hwakakosha kwazvo nekutsemuka kwefiber mukugadzira mapepa.Izvo zvinozoenderana nekuti yakawanda sei mafiber akatyoka uye akaremara.Naizvozvo, mafiibhi ane dhayamita diki uye madziro akakora akaoma, haasi nyore kupwanywa, uye anoumba nyore-akawanda density mapepa.
Mhando yepulp inewo simba guru pahuwandu hwepepa.Kazhinji kutaura, goho rakakwirira pulp> thermomechanical pulp> kraft pulp> tsvina pulp.Zvigadzirwa zvakasiyana zvine vhoriyamu yakasiyana mune imwechete pulp, hardwood> softwood.Iyo yakanyanya bulkiness yemhando yepamusoro-yegoho pulp haina kufananidzwa nemamwe mapundu, saka yakakwira-goho pulp inoshandiswa zvakanyanya kutsiva bleached kraft hardwood pulp mumapepa egiredhi repamusoro.Sarudzo uye chiyero chemhando yepulp ndiyo kiyi kune yazvino-yakasununguka yakasununguka yekugadzira mapepa tekinoroji.Kuwedzera mbesa ine goho repamusoro kuvandudza kuwanda kwemapepa pari zvino ndiyo nzira inoshanda zvakanyanya inoshandiswa zvakanyanya nemapepa.
Volume chinhu chakakosha zvikuru chebepa.Pepa repamusoro pehuwandu hwehuwandu hunogona kuchengetedza kuoma kwakakosha, kuderedza kushandiswa kwefiber, kuchengetedza mari yepulp uye kugadzirisa kuwanda kwehuwandu.Nzira dzinonyanya kushanda pari zvino dzinosanganisira kuwedzerwa kwegoho repamusoro, sarudzo ye pulp uye maitiro ekugadzirisa.Iko optimization uye kusimudzira kwezvitsva zvakawanda zvinowedzera zvakare yakakosha yekutsvagisa gwara.
