Hunhu hwemakemikari hwezvinhu zvemushenjere

Zvinhu zvemubamboo zvine cellulose yakawanda, chimiro chefiber chakatetepa, hunhu hwakanaka hwemakanika uye plasticity. Seimwe nzira yakanaka yekugadzira mapepa emapuranga, mubamboo unogona kusangana nezvinodiwa zvemubamboo pakugadzira mapepa epakati nepamusoro. Zvidzidzo zvakaratidza kuti makemikari emubamboo uye hunhu hwefiber zvine hunhu hwakanaka hwepulping. Kushanda kwemubamboo pulp kuri pechipiri kune coniferous wood pulp, uye kuri nani pane mubamboo une mashizha akafara uye pulp yehuswa. Myanmar, India nedzimwe nyika dziri pamberi penyika mukugadzira mubamboo pulping nepapermaking. Zvigadzirwa zvemubamboo pulp nepaper zveChina zvinonyanya kutengwa kubva kuMyanmar neIndia. Kuvandudza indasitiri yemubamboo pulping nepapermaking kwakakosha zvikuru mukuderedza kushomeka kwezvinhu zvemubamboo pulp zviripo pari zvino.

Mishenje inokura nekukurumidza uye inogona kukohwewa mumakore matatu kusvika mana. Pamusoro pezvo, masango emishenje ane simba guru rekuisa kabhoni, zvichiita kuti mabhenefiti ehupfumi, zvakatipoteredza uye magariro evanhu eindasitiri yemishenje ave akakurumbira zvikuru. Parizvino, tekinoroji yekugadzira mishenje yemishenje muChina nemidziyo yakura zvishoma nezvishoma, uye michina mikuru yakaita sekugera nekupwanya mishenje yave kugadzirwa munyika. Mitsetse mikuru nepakati yekugadzira mapepa emishenje yave kugadzirwa mumaindasitiri uye yakaiswa mukugadzirwa muGuizhou, Sichuan nedzimwe nzvimbo.

Hunhu hwemakemikari hwemushenjere
Sechinhu chinogadzirwa ne biomass, mushenje une zvikamu zvitatu zvikuru zvemakemikari: cellulose, hemicellulose, uye lignin, kuwedzera kune pectin shoma, starch, polysaccharides, uye wax. Nekuongorora kuumbwa kwemakemikari uye hunhu hwemushenje, tinogona kunzwisisa zvakanakira nekuipira kwemushenje se pulp uye bepa.
1. Bamboo ine cellulose yakawanda
Bepa rakapedzwa zvakanaka rine zvinodiwa zvakanyanya zve pulp, zvichida kuti cellulose ive yakawanda, zviri nani, uye zviri nani kuti lignin, polysaccharides nezvimwe zvinotorwa, zviri nani. Yang Rendang nevamwe vake vakaenzanisa zvikamu zvikuru zvemakemikari zvezvinhu zve biomass zvakaita se bamboo (Phyllostachys pubescens), masson pine, poplar, uye wheat straw vakaona kuti cellulose yaive masson pine (51.20%), bamboo (45.50%), poplar (43.24%), uye wheat straw (35.23%); hemicellulose (pentosan) yaive poplar (22.61%), bamboo (21.12%), wheat straw (19.30%), uye masson pine (8.24%); lignin yaive bamboo (30.67%), masson pine (27.97%), poplar (17.10%), uye wheat straw (11.93%). Zvinogona kuonekwa kuti pakati pezvinhu zvina zvinoenzaniswa, mushenjere ndiwo mushonga unotsiva masson pine.
2. Mashinda emubamboo akareba uye ane chiyero chakakura
Avhareji yehurefu hwemafiber ebamboo i1.49~2.28 mm, avhareji yedhayamita i12.24~17.32 μm, uye aspect ratio i122~165; avhareji yehukobvu hwemadziro efaibha i3.90~5.25 μm, uye ratio yemadziro-kune-cavity i4.20~7.50, inova fiber yakakora ine aspect ratio yakakura. Zvinhu zvepulp zvinonyanya kushandisa cellulose kubva kuzvinhu zvebiomass. Zvinhu zvakanaka zvebiofiber zvekugadzira mapepa zvinoda cellulose yakawanda uye lignin shoma, izvo zvisingangogone kuwedzera goho repulp chete, asiwo kuderedza dota uye extracts. Bamboo ine hunhu hwemafiber marefu uye aspect ratio yakakura, izvo zvinoita kuti fiber isanganiswe kakawanda payuniti imwe neimwe mushure mekunge bamboo pulp yagadzirwa kuita bepa, uye simba repepa riri nani. Nokudaro, mashandiro epulping ebamboo ari pedyo neaya ehuni, uye akasimba kupfuura mamwe maruva ehuswa akadai seuswa, uswa hwegorosi, uye masagasse.
3. Faibha yemubamboo ine simba rakawanda refaibha
Selulosi yemubamboo haingogone kudzokororwa chete, inoora, inoenderana nehupenyu, inonyungudika mumvura, uye ine hunhu hwakanaka hwekudzivirira kupisa uye hunyanzvi hwemakanika, asiwo ine hunhu hwakanaka hwemakanika. Dzimwe nyanzvi dzakaita bvunzo dze tensile pamhando gumi nembiri dzemafiber emubamboo uye dzakaona kuti elastic modulus yavo uye simba re tensile rakapfuura revanogadzira mafiber emusango anokura nekukurumidza. Wang nevamwe vake vakaenzanisa hunhu hwe tensile mechanical hwemhando ina dzemafiber: bamboo, kenaf, fir, uye ramie. Mhedzisiro yacho yakaratidza kuti tensile modulus uye simba re fiber yemubamboo zvaive zvakakwirira kupfuura zvezvimwe zvinhu zvitatu zve fiber.
4. Bamboo ine dota rakawanda uye inotorwa kubva muvhu
Zvichienzaniswa nematanda, mushenje une dota rakawanda (rinenge 1.0%) uye 1% NAOH extract (inenge 30.0%), izvo zvinozoburitsa tsvina yakawanda panguva yekupura, izvo zvisingakodzeri kuburitswa kwemvura yakasviba muindasitiri yepulp nemapepa, uye zvichawedzera mari yekudyara yemimwe michina.

Parizvino, mhando yezvigadzirwa zveYashi Paper zvemabamboo pulp paper zvasvika pazvinodiwa zveEU ROHS, zvapasa bvunzo dzeEU AP (2002)-1, US FDA nedzimwe bvunzo dzepasi rose dzechikafu, zvapasa chitupa cheFSC 100% forest, uye ndiyo kambani yekutanga muSichuan kuwana chitupa chekuchengetedza neutano muChina; panguva imwe chete, yave ichiongororwa sechigadzirwa che "quality supervision sampling qualified" neNational Paper Products Inspection Center kwemakore gumi akateedzana, uye yakawanawo mibairo yakaita se "National Quality Stable Qualified Brand and Product" kubva kuChina Quality Tour.
