IP Zuva Pepa's PM23 # muchina unonyanya kugadzira bepa retsika, kusanganisirabepa rekudhinda reoffset uyekopi bepa , nekubuda kwepagore kwematani anopfuura 300,000. Muchina uyu wakashongedzerwa nesimbi bhandi calender, iyo ine mabhenefiti makuru mukugadzirisa kutsetseka.
Imwe huwandu hwekuzadza inowedzerwa kune bepa panguva yekugadzira. Anowanzo shandiswa papermaking fillers ndeye calcium carbonate, talc, kaolin, etc. Mapepa ekugadzira mafirita akadai se calcium carbonate ndiwo mativi ane chikamu chikuru mubepa kunze kwe fiber raw materials, anoshandiswa zvakanyanya nekuda kwemutengo wakaderera, kuderedza huwandu hwepepa. fiber, kuderedza mutengo wekugadzira, uku uchivandudza kutsetseka uye kupenya kwemhepo kwepepa; kuvandudza maoptical properties (kuchena, opacity uye gloss), kudhinda kushanda uye kunyora kushanda kwepepa.
Nekudaro, mushure mekuwedzera mafirita, nekuda kweadiki madiki ekuzadza uye yakakura chaiyo nzvimbo, iyo yechinyakare kuzadza maitiro inotadzisa iyo hydrogen bonding pakati pemafibhi uye kuderedza simba reiyo.bepa . Iyo yakawanda mafiritsi anowedzerwa mukugadzira maitiro, iyo inowedzera kusungirirwa kwesimba pakati pemafibhi mubepa kunokanganisa, uye zvakanyanya kuoneka kuderera kwesimba repepa. Pamusoro pezvo, kunyangwe kuwedzera mafirita pamapepa kunogona kuvandudza kusefa kwemvura kwechikamu chewaya uye kuwedzera kuoma kwepepa rakanyorova, asi kuwedzera kwemukati mekuzadza kunowanzo kutungamirira mukudzikira kwekuchengetwa kwemafiritsi panguva yekusefa kwemvura, bepa muchina saizi kutadza uye zvimwe zvinokanganisa. Yakawandisa filler yemukati inoderedzawo simba repamusoro pepepa, zvichikonzera chiitiko che lint uye kurasikirwa kwehupfu panguva yekushandiswa kwepepa rakapedzwa.
Kuti kuderedzatsika bepamutengo wekugadzira,IP Pepa reZuva rakanyatso shandira pamwe neAmerican Special Mining Company kuunza yakakwirira-kuchengeta sitachi gelatinization michina. Kutanga, iyo starch inogadziriswa mumvura inodziya tangi, uye zvino yakasanganiswa nezadza uye yakawedzerwa kune yepakutanga filler kuwedzera pfungwa. Zvigumisiro zvinoratidza kuti kana inenge 2 kg ye starch yakawedzerwa patani yepepa, chiyero che starch mumhepo yakanyorova inoderedzwa ne 2 kg, madota anogona kuwedzerwa ne 1.5%, kuchengetedza kwehurongwa kunovandudzwa zvakanyanya. uye kuwanda kwezvinowedzera zvinobudirira kuderedzwa; iyo indekisi yesimba haina kuderedzwa zvakanyanya. Nekudaro, ine imwe mhedzisiro yakaipa pakupera kwemvura yemuchina wepepa, uye ichakonzeravamwematambudziko akadai sekunamatira humburumbira.
