Pulp kuchena kunoreva mwero we cellulose yemukati uye huwandu hwehutsvina huri mupulp. Ideal pulp inofanira kunge yakapfuma mu cellulose, nepo zvinyorwa zvehemicellulose, lignin, madota, zvinyorwa uye zvimwe zvisiri-cellulose zvikamu zvinofanira kunge zvakaderera sezvinobvira. Iyo cellulose yemukati inotarisisa kuchena uye kukosha kwekushandisa kwe pulp, uye ndiyo imwe yepakati zviratidzo zvekuongorora pulp mhando. Hunhu hwekuchena kwepamusoro pulp:
(1) kusimba kwepamusoro, cellulose ndicho chinhu chikuru chinoumba simba rebepa, kuchena kwakakwira kunoreva yakakwira cellulose yemukati, saka bepa rakagadzirwa rine simba rekuramba kubvarura, kupeta kupeta uye zvimwe zvinhu zvemuviri uye zvemagetsi, kuwedzera hupenyu hwesevhisi. bepa.
(2) Kubatana kwakasimba, pure cellulose fibers inogona kuumba hukama hwepedyo hwakarukwa pakati pepepa kuti iwedzere kubatana kwemukati, kuitira kuti bepa risave nyore kuderedzwa kana kuputswa kana richiiswa pasi pesimba rekunze, kuwedzera simba rose repepa. .
(3) kuchena kwepamusoro, kuvapo kwetsvina kunowanzokanganisa kuchena uye kupenya kwepepa. Yakanyanya kuchena pulp, nekuda kwekubviswa kwehuzhinji hwemavara emavara, inoita kuti pepa riratidze kuchena kwechisikigo kwakakwirira, iyo inonyanya kukodzera kudhinda, kunyora uye kurongedza, nezvimwewo, uye inowedzera maonero echigadzirwa.
(4) zviri nani magetsi ekudzivirira zvivakwa, cellulose ine yakanaka insulating zvivakwa, nepo zvisiri-serusero zvikamu mu pulp, senge lignin, zvinogona kunge zvine conductive kana hygroscopic zvinhu, zvinokanganisa kuvharwa kwemagetsi kwepepa. Naizvozvo, bepa rakagadzirwa kubva kune-yakachena pulp rine huwandu hwakawanda hwekushandisa muinjiniya yemagetsi, senge cable insulation bepa, capacitor bepa, nezvimwe.
Yakakwira kuchena pulp kugadzirira, iyo yemazuva ano indasitiri yemapepa inoshandisa akasiyana emhando yepamusoro pulping maitiro, akadai semakemikari pulping (kusanganisira sulphate pulping, sulphite pulping, nezvimwewo), mechanical pulping (senge thermal grinding mechanical pulp TMP) uye kemikari mechanical pulping (CMP). ) zvichingoenda zvakadaro. Aya maitiro anovandudza kuchena kwe pulp nekubvisa kana kushandura iyo isiri-cellulosic zvikamu zveiyo mbishi.
High kuchena pulp inoshandiswa zvakanyanya munzvimbo dzakawanda dzakadai sepamusoro-giredhi retsika bepa, kurongedza bepa, hunyanzvi bepa (semuenzaniso, bepa rekuvhara magetsi, pepa resefa, bepa rekurapa, nezvimwewo) uye bepa repamba, rinosangana nemhando yepamusoro yemhando yepepa. zvinodiwa nemaindasitiri akasiyana.
Yashi Pepa rinongogadzira zana muzana virgin bamboo pulp, single ci bamboo fiber, inova sarudzo yakanakisa yekuchena kwepamusoro uye yemhando yepamusoro pepa reimba.
