Kraft bepa sechinhu chakajairika muindasitiri yekudhinda uye yekurongedza, saka iwe unoziva mashandisirokraft bepazvakarurama?
Kushandisa kraft bepa
Muindasitiri yekudhinda nekurongedza, kraft bepa rinowanzo shandiswa kudhinda mavhavha ekutaura kwemari, mahamvuropu, kutakura zvinhu, mabhegi ezvinyorwa, mabhegi eruzivo, mabhegi emaoko, mabhokisi emafaira, mabhegi emafaira, nezvimwe.
Tsanangudzo ye kraft bepa
Kazhinji kushandiswakraft bepaine zvinyorwa zvakasiyana-siyana zvakadai se60g/m2, 70g/m2, 80g/m2, 100g/m2, 120g/m2, 150g/m2 uye kunyange 250~450g/m2.
Hunhu hwe kraft bepa
Zvakanakira:Kraft bepa rine zvakanakira kusimba kwakanaka, kuomarara uye kusimba magadzirirwo, kwete nyore kubvaruka uye kutyoka, uye inoshingirira kupfeka uye kubvaruka.
Zvakaipa:kraft bepa pamusoro roughness, nyore kuoneka pabhandi pasi nhonga, kudonha bvudzi, de upfu phenomenon, kuchena, flatness, kutsvedzerera ari urombo.
Kushandiswa kwekraft mapepa ehunyanzvi
① Kurembera uye kugadzirisa kurapa kwakanyorova: danho rekutanga kune kusaenzana kwepamusoro uye rakaputswa bepa rabviswa, danho rechipiri richava pepa repasi tsvina, pepa dota rakachena, rinorembera kuomesa kurapa, kuitira kuti tembiricha uye humidity yekraft bepa uye offset. kudhinda tembiricha yemusangano uye hunyoro kuchengetedza kuenderana.Kraft bepamushure mekurembera kuomesa mwando kurapwa, akaisa pamusoro pepepa stack akatsikirirwa bepa splint, nematombo makuru, simbi ndiro compaction, kudzivisa bepa fluffy kwete kusimba.Kuita izvi kunogona kudzivirira kubuda kwekraft bepa nekuda kwekusaenzana hunyoro hunoonekwa pane chiitiko chebuckling pasi pepick.
② sarudza yakanaka modhi: nekuda kweiyo 80g/m2 gobvu kraft bepa, mune pepa rekutumira nozzle kazhinji haigone kutora bepa, saka kana kraft bepa ukobvu ≥ 80g/m, zviri nani kusashandisa madiki mana kana masere akavhurika. offset kudhinda muchina kudhinda.Pamusoro pezvo, nekuda kwehupamhi hwemapepa madiki, zviri nyore kupeta kana kuwanda-mapepa kukundikana, kana pepa rakatsvetwa mukuendeswa kwepepa.Uye nefolio offset press kana full-opening offset press printing ≥ 80g/m of kraft paper, mhedzisiro yacho ichava nani.
③ gadzirisa dhizaini yekudhinda pepa rekutumira system: ukobvu hwebepa hwakakura huri nyore kukonzeresa tsaona yekumisa, saka usati watanga muchina wekudhinda unofanirwa kunge uri pamberi pe punch control, skew control, kaviri kudzora, uye zvimwe zvigadzirwa zvemagetsi kugadzirisa zvakakodzera, kudzivirira kraft bepa kupfuura mumwe mupumburu zvakaipa muchina.Inofanirwa kugadziridzwa kune saizi yekusveta vhoriyamu yekusveta vhoriyamu, bepa rekusveta nozzle uye bepa rekudya rinosveta nozzle kushandisa dhayamita uye ukobvu ihombe rabha mhete.
④ chengetedza silinda yekudhinda uye rubber silinda yepakati chinhambwe chisina kuchinjika: gadzirisa nzvimbo yepakati yechiratidzo silinda uye silinda yerabha uye chengetedza nzvimbo yepakati isina kuchinjika, kana uchidhinda 250 ~ 450g / m kraft bepa, iyi nzvimbo yepakati inogona kuwedzerwa ne 0.2 ~ 0.4 mm.kraft bepa pamusoro roughness, kutsvedzerera kwakashata, kusimba kwebepa kwakaderera pane copperplate bepa, offset bepa, saka, kudhinda kraft bepa, asi zvakare zvinoenderana nekuwedzera kudhinda kudhinda.Pakudhindakraft bepaUkobvu ≥ 400g / m, silinda yepureti yekudhinda uye gap rerubha silinda ye3.95mm, silinda yerabha uye impression cylinder gap kugadziriswa kwe3.40mm, iyo yakazara pasuru yekumisikidza cylinder yepureti ye0.65 ~ 0.75mm, iyo yakazara pasuru lining. silinda yerabha ye3.15 ~ 3.35mm.Kana bepa rekudhinda kubva kune gobvu kusvika kune rakaonda, rinofanira kudhonzwa kubva kune inodhinda ndiro lining mune yakaderedzwa ukobvu hwePackage lining, pamwe nerubber cylinder package;kana bepa kubva kutete kusvika kune gobvu, rinofanirwa kudhonzwa kubva muhumburumbira werabha kuti uwedzere ukobvu hwepakeji lining, pamwe neinodhinda ndiro cylinder package.
⑤ kraft bepa pamusoro pehutsinye, kusununguka, nyore kuita hupfu, bvudzi, saka kana uchidhinda kunyatsokwesha silinda yerabha uye cylinder yepureti yekudhinda, kudzivirira bvudzi rebepa, hupfu hwepepa hunonamira kune silinda yerabha uye cylinder ndiro yekudhinda uye kukanganisa kuchinjisa inki, zvichikonzera mifananidzo kubva mundiro, kushaikwa kwepeni yakatyoka mutsara.Kana zvakasangana muzhizha apo monochrome kudhinda, kraft bepa bvudzi, upfu matambudziko akakomba, anogona kudhindwa pamberi overlay layer yemvura, izvo zvinogona zvinobudirira kuderedza bepa bvudzi, upfu chiitiko, kuitira kuti bepa sandara.
