Fashoni chena seti yekuratidzira bhokisi refodya kurongedza (seti yega yega yemabhokisi gumi, bhokisi rega rega re7 mapaketi)

White cardboard imhando yebepa gobvu rine kusimba uye huremu hukuru. Nemhaka yokuti nzvimbo yacho haina ruvara, inowanzonzi white cardboard. Kadhibhodhi chena yeChina yakakamurwa kuita magiredhi matatu A, B, C. Kuchena kwegiredhi A hakusi pasi pe92%; B giredhi haisi pasi pe87%; C giredhi haisi pasi pe82%.
Iyo mbishi yewhite cardboard ndeye 100% bleached chemical
Kadhibhodhi chena yemapakiti efodya inoda kuomarara kwakanyanya, kuramba kutyora, kutsetseka uye kuchena. Mapepa epamusoro anodiwa akapfava, hapana mitsetse, mavara, dents uye mabumps, warping uye deformation yekugadzirwa. Sezvo pakiti yefodya ine chena kadhibhodhi kunyanya kushandisa high-speed gravure kudhinda muchina kudhinda, saka chena kadhibhodhi tension index zvinodiwa zvakakwirira. Tension resistance inozivikanwawo sekuti tension simba kana kuti tensile simba, izvo zvinoreva kuti tension yakanyanya iyo bepa rinokwanisa kumira kana rikatyoka, rinoratidzwa mu kN/m. High-speed gravure kudhinda muchina kukweva mapepa mipumburu, yakakwirira-nokukurumidza kudhinda kutsungirira makakatanwa hombe, kana chiitiko kuputika bepa kazhinji, anosungirwa kukonzera kakawanda downtime, kuderedza kushanda zvakanaka, asiwo kuwedzera kurasikirwa bepa.
Kune marudzi maviri emakadhibhodhi machena emapaketi efodya, imwe iFBB (yellow core white card), imwe iSBS (white core white card), mapaketi efodya anoshandisa FBB neSBS ane divi rimwe chete akavharidzirwa makadhibhokisi machena, FBB ine matatu akaturikidzana. ye pulp, kumeso uye yepasi layer uchishandisa sulfate huni pulp, iyo yepakati layer uchishandisa kemikari mechani kukuya huni pulp. Rutivi rwemberi (rutivi rwekudhinda) ndiro rekuvhara, iro rinoiswa maviri kana matatu squeegees, nepo reverse side isina coating layer. Sezvo chikamu chepakati chakagadzirwa nemakemikari uye mechanically milled huni pulp, pulp ine goho rakakwirira kune huni (85% -90%), uye mari yekugadzira yakaderera, saka mutengo weFBB cardboard wakaderera.
FBB pulp ine mamwe marefu mafibhi uye mashoma madiki uye fiber bundles, saka ukobvu hwebepa rakapedzwa huri nani, uye giremu imwechete yeFBB yakanyanya kukora kupfuura SBS, iyo inowanzo umbwa nezvikamu zvitatu zvepulp, iyo yepamusoro layer. , core layer uye yepasi layer zvese zvinoshandisa bleached sulfate huni pulp. Rutivi rwemberi (rutivi rwekudhinda) ndiro jira rekuputira, rinoshandiswa kaviri kana katatu neine squeegee yakafanana neFBB, nepo reverse side isina coating layer. Sezvo iyo core layer yakagadzirwawo ne bleached sulfate pulp, kuchena kwacho kwakakwira, saka inonzi white core white card. Panguva imwecheteyo, iyo pulp fibers idiki uye bepa rakaomarara, saka SBS yakanyanya kutetepa kupfuura FBB yehuremu hwakafanana hwegiramu. Semuenzaniso, ukobvu hwe230g/m2 FBB yeHongta Renheng i320μm, ukuwo ukobvu hwe230g/m2 SBS i295μm.
