Pepa, Wikipedia inoitsanangura sechinhu chisina kurukwa chakagadzirwa neshinda dzezvirimwa zvinogona kupetwa pamadiro uye kushandiswa kunyora.
Nhoroondo yemapepa inhoroondo yebudiriro yevanhu. Kubva pakubuda kwebepa muWestern Han Dynasty kuenda kuCai Lun yakavandudzwa kugadzira mapepa tekinoroji muEast Han Dynasty, uye ikozvino, bepa harisisiri kungotakura mutakuri wekunyora, asi rinogona kushandiswa kune zvimwe zvinangwa zvakaita sekudhinda, kurongedza, indasitiri. , uye hupenyu hwezuva nezuva.
01 Chikamu chekushandisa
Zvigadzirwa zvinoshandiswa zvinosanganisira: bepa retsika, maindasitiri uye ekurima tekinoroji mapepa, pepa rekurongedza uye pepa reimba.
bepa renyika yangu rinotengwa kunze kwenyika rinonyanya kusanganisira bepa retsika (newsprint, bepa rakavharwa, offset bepa, kunyora bepa) uye kurongedza (kraft bepa, chena board bepa, marata base bepa, chena makadhibhokisi, cellophane, nezvimwewo).
02 Kuongorora Pfungwa Huru
Chitarisiko

Yakapfava, yakachena, nezvimwe.
Kuonekwa kwepepa chinhu chakakosha pakusarudza kunaka kwepepa. Izvo hazvisi kungokanganisa kunaka kwepepa, asi kumwe kukanganisa kwechitarisiko kuchakanganisawo kushandiswa kwepepa.
Iko kutaridzika kwemhando yekuongorora kwebepa kunonyanya kushandisa mwenje wekuongorora, flat light inspection, squint inspection uye neruoko rwekuongorora. Iyo mapepa epamusoro anodiwa kuti ave akatsetseka uye akachena, uye hapana kupeta, makwinya, kukuvadzwa, zvidhinha zvakaomarara, mavara-anotumira makwapa, hove chiyero chemavara, misiyano yemavara, mavara akasiyana-siyana uye manzwi akajeka anotenderwa.
Ongorora: Kutariswa kwemhando yemhando yepepa rinounzwa kunze kwenyika kunoitwa zvinoenderana neZBY32033-90.
Zvinhu zvenyama
Kutarisa: nekupatsanura
Mapepa akasiyana ane zvinodiwa zvakasiyana
Newsprint: Newsprint inoda pepa rakapfava uye rinotsikirira, uye iyo bepa repamusoro rinofanira kunge rakanyura zvakanyanya. Kuve nechokwadi chekuti inki yekudhinda inogona kuoma nekukurumidza panguva yekudhinda. Iro bepa rinodikanwa kuti rive rakatsetseka pamativi ese ari maviri, rinoenderana muhukobvu, nekupenya kwakanaka, pasina lint kana smear panguva yekudhinda, mapatani akajeka, uye pasina kukanganisa kwemaonero. Iro bepa rinoda kusimba kusingachinji kumigumo yese yemupumburu, majoini mashoma, uye simba rakanaka rekusimba kuti rienderane nezvinodiwa zvekudhinda zvemichina yekumhanyisa inotenderera inodhinda.
Hunhu hunodiwa hwepepa rakaputirwa: kutsetseka. Iyo pepa repamusoro rinofanira kunge rakatsetseka zvakanyanya kuitira kuti rikwanise kusangana zvakakwana nechepamusoro pechidzitiro chemhangura ndiro panguva yekudhinda, nekudaro kuwana yakapfava uye yakajeka mutsara wepateni ine chimiro chechokwadi uye kupenya kunofadza.
White board bepa: White board bepa rinowanzoda kusimba kwemavara, kutsetseka kwepasi, kuenderana ukobvu, lint-isina mapepa pamusoro, yakanaka absorbency uye diki yekuwedzera mwero kuti ienderane nezvinodiwa zveakawanda-mavara overprinting. Kuti zvizadzise zvinodikanwa zvekugadzira bhokisi, pepa chena rinofanira kuva nehunhu hwekuoma kwepamusoro uye kupeta kwakasimba kuramba.
Kraft bepa: Kraft bepa kadhibhodhi rinonyanya kushandiswa kurongedza zvigadzirwa, saka magadzirirwo epepa anofanira kunge akaoma, ane simba rinoputika, simba rekupwanya mhete uye kubvarura simba. Mukuwedzera, inofanira kuva nekudzivirira kwemvura yakawanda kuitira kuti panguva yekufambisa kwegungwa kana kuchengetedza kunotonhora, simba racho harizove rakanyanya kuderedzwa nekuda kwehuwandu hwekunyorova kwemvura, zvichikonzera kukanganisa kwebhokisi. Iro kraft bepa rinoda kushandiswa pakudhinda rinofanirawo kuva nehumwe hunyoro.
Corrugated base bepa: Corrugated base bepa inoda yakanaka fiber bonding simba, yakatsetseka pepa pamusoro, uye kusimba kwakanyanya uye kuoma. Imwe dhigirii ye elasticity inodiwa kuchengetedza kuvhundutsa-kusimbisa uye kusamira-kumanikidza kugona kwemakatoni akagadzirwa. Naizvozvo, kuputika kwesimba uye mhete yekupwanya simba (kana kuti flat kupwanya simba) ndiwo maratidziro makuru anoratidza simba remarata base bepa. Mukuwedzera, iyo indekisi yehunyoro inofanirawo kudzorwa. Kana hunyoro huri hudiki, bepa rinoita brittle uye rinogona kutsemuka panguva yekugadzira corrugation. Kunyanya kunyorova kunokonzeresa kunetsa mukugadzirisa. Kazhinji, hunyoro hunofanira kunge huri 10%.
Cellophane: Cellophane iri pachena muruvara, inopenya kumusoro, yunifomu mukukora, yakapfava uye inotambanuka. Ichazvimba uye ichiva yakapfava mushure mekunyudzwa mumvura, uye inozodzikira mushure mekuoma. Iine mvura yakakwira uye inokwanisa kuita kuunyana uye kunyange kunamira kana yaiswa muhunyoro. Pamusoro pezvo, nekuda kwekurongeka kwakafanana kwe cellulose microcrystals munzira yelongitudinal, iyo longitudinal simba rebepa rakakura uye inochinjika idiki. Kana paine makatsemuka, anotsemuka pasi pesimba shoma. Cellophane haina mhepo, haina mafuta uye haina mvura.
Bepa rekudhinda reoffset: Bepa reoffset rinoshandiswa kune akawanda-mavara overprinting. Pamusoro pekuchena kwakanaka uye guruva shoma, ine zvakare zvinodikanwa zvakakwirira zvekusimba kwebepa, kusimba kwesimba, uye kupeta kuramba. Panguva yekudhinda, pamusoro pepepa haidonhedze lint, hupfu, kana kudhinda-kuburikidza. Izvo zvinodiwa zvakafanana neaya akavharidzirwa mapepa.
