Duplex board inogadzirwa nepamusoro pulp uye pasi pulp. Chimiro chayo chinonyanya kukamurwa kuita pasi pasi, core layer, lining layer, surface layer uye coating layer. Rudzi rwepasi pepepa rewhiteboard grey. Inogadzirwa kubva kumarara pepanhau ne deinking, saka kuumbwa kwezasi kwepasi kwakanyatsosanganiswa; pamusoro pacho pakachena, inzvimbo yakatetepa yakavharwa yakasanganiswa nekemikari mbishi zvinhu zvakaita sekaolin poda nenamira. Iyo yekumusoro layer (yakavharwa pamusoro) ine kuchena kwepamusoro, kunaka inki kunyura, kutsvedzerera uye kudhinda gloss, uye kadhibhodhi pachayo ine kuoma kwakanaka uye kupeta kuramba. Mushure mepamusoro pepepa re duplex rakaputirwa, kushanda kwepamusoro kwakagadziridzwa zvakanyanya. Inogona kusangana nezvinodiwa zvemhando yepamusoro yekudhinda kwemavara, inogona kuve yemhando yepamusoro yepakati uye yepamusoro-yekupedzisira midziyo yekurongedza mabhokisi.
Foling box board kadhibhodhi chena yakakora uye yakasimba. Yakagadzirwa ne100% yakacheneswa kraft huni pulp uye yakarohwa mahara. Iyo inogadzirwa nekuwedzera chena mafirita senge talc uye barium sulfate pamushini weFourdrinier bepa uye inogadziriswa necalendering kana embossing.
Pachine misiyano iri pachena mukunyudza uye roughness pakati pe duplex board neFBB.FBB ine yakanyanya absorbency uye yakaderera roughness. Kuwedzera kunyura kunogona kuita kuti kuve nyore kuwana dot, nepo kuderera kwehukasha kuchikonzera kushomeka kwepamusoro pepepa pasi pekudzvanywa, uye inoda firimu reinki rakatetepa, rinobatsira kuderedza kuwana dot. Naizvozvo, iyo duplex bhodhi yakaderera kune iyo FBB maererano nezwi reproducibility.
Pepa kutsetseka, kupenya uye absorbency zvakare zvinhu zvakakosha. Kutsvedzereka kwepamusoro kweFBB kwakati wandei. Kana iyo inki yakadhindwa pabepa, iyo capillary mumucheka wekuputira inotora zvakaenzana, kunyangwe huwandu hweinki hudiki, inogona kuve nechokwadi chepamusoro chekufambisa. Iyo yakanyanya kugadzikana uye inogona kukurumidza kugadzira yunifomu uye yakaoma inki firimu. Kubwinya kwezvinhu zvakadhindwa zvakanaka kwazvo, ruvara rwakajeka, uye zvidimbu zvakapfuma. Bepa rine kutsetseka kwepamusoro, kupenya kwakasimba, kupenya kwakanaka, uye kana mwenje unopfuura nepainki layer ndokurova bepa, mwenje wakawanda unozopinda zvakare kuburikidza neingi layer nenzira yespecular reflection, yopinda mucherechedzi. maziso. Chikamu ichi chete chechiedza chinogona kuratidza mavara einki. Kune rumwe rutivi, duplex board ine yakakura zvikuru pamusoro pores, isina kuenzana pamusoro, shoma ingi vhoriyamu, bepa haigoni kubata zvizere kudhinda inki, uye chinja mwero yakaderera; kana vhoriyamu yeinki yakakwira, mwero wekutamisa wakanyanya, kunyura kwakawandisa, uye mazhinji ebhinda muinki anotorwa nebepa, pigment zvidimbu hazvina kuchengetedzwa zvakakwana, iyo inki haina kukurumidza, uye ruvara. haina kuoma.
