Iwo mavara mabhokisi anoshandiswa kurongedza chigadzirwa uye mabhokisi ekurongedza eakasiyana ezvigadzirwa zvekutakura anonyanya kugadzirwabhodhi renyanga dzenzou . Mushure mekucheka, kudhinda uye kunotevera kugadzirisa, inova yedu chigadzirwa kurongedza bhokisi.
Nhasi, apo kunakidzwa kwezvinhu kunowedzera kukosheswa, vanhu vane zvakakwirira uye zvepamusoro zvinodiwa zvemhando yekurongedza makadhibhodi. Ivory board (inozivikanwawo seyakaputirwa chena kadhibhodhi kanaFBB ) ndeyepamusoro-giredhi yekurongedza zvinhu, uye kutaridzika kwayo kwakanaka kwavewo chinangwa chekutsvaga kwevanhu. Nekudaro, iyo yero chiitiko cheiyo yakavharwa chena bhodhi bepa panguva yekushandiswa inokanganisa zvakanyanya kutaridzika kwekunze kwekurongedza. Iko kuchena kwekadhibhodhi chena kunoreva chiitiko chekuti kuchena kwechigadzirwa kunodzikira kusvika kumwero wakati mushure meimwe nguva yekuchengetedza kana kuratidzwa kwezuva.
Mhedzisiro yetsvagiridzo yazvino inoratidza kuti chiitiko cheyero ndechekuti zvinhu zvepamusoro zvebhokisi rinopetwa rinosangana neokisijeni mumhepo, iyo inoshandura chimiro chemakemikari yechinhu chepamusoro, zvichikanganisa maonero evanhu. Chiyero che oxidation chinotarisa kuoma kweyero.
Zvinhu zvinokanganisa yellowing yewhite cardboard kunyanya zvinosanganisira zvinhu zvinotevera: coated whiteboard base bepa, fluorescent whitening agent, color pigment, coating adhesive, etc. Kuvandudza maitiro ekugadzirwa kwepepa rekutanga, sarudza high-quality fluorescent whitening agents, ruvara rwemavara, gadzirisa chiyero chakanaka, uye nesayenzi. sarudza yakanakisa kusanganiswa kweadhesives, iyo inogona kunyatso kudzikisa yellowing phenomenon yekavharwa whiteboard paper; Zviwedzerwa, zvakadai se nano-silicon-based oxides, zvigadzirwa zvemakemikari zvakadai seUV absorbers uye antioxidants, zvichaderedzawo chiitiko cheyero chepepa jena rakaputirwa; kusimbaradza kutonga kwekugadzira kwewhiteboard bepa uye kudzivirira kwezvinhu zvese zvekurongedza uye kuchengetedza mamiriro zvakare inzira inoshanda yekugadzirisa kuyero kwekadhibhodhi chena.
Dzora maitiro ese anosanganisirwa, mira uye gadzirisa mashandiro, uye mhando yekadhi chena yakavharwa ichave yekutanga-kirasi.
