China's Four Great Inventions
Kugadzira mapepa ndechimwe chezvigadzirwa zvina zvikuru zveChina. Pepa ndiyo crystallization yeruzivo rwenguva refu uye huchenjeri hwevanhu vekare veChinese vanoshanda. Chinhu chakatanhamara munhau yebudiriro yavanhu.
Mugore rekutanga reYuanxing muMabvazuva Han Dynasty (105), Cai Lun akavandudza kugadzira mapepa. Aishandisa makwati, misoro yehemp, machira ekare, mambure ehove nezvimwe zvinhu zvakabikwa, uye kugadzira mapepa nenzira dzakaita sekupwanya, kupura, kufinya nekubheka. Uku ndiko kwakabva bepa ranhasi. Izvo zvigadzirwa zvemhando iyi yemapepa zviri nyore kuwana uye zvakachipa zvakanyanya. Hunhu hwave nani uye zvishoma nezvishoma hwave kushandiswa zvakanyanya. Kuti vayeuke zvakaitwa naCai Lun, zvizvarwa zvakatevera zvakadaidza rudzi urwu rwebepa "Cai Hou Paper".
Munguva yeTang Dynasty, vanhu vaishandisa bamboo seyakabikwa kugadzira pepa bamboo, iyo yakaratidza budiriro huru mukugadzira mapepa tekinoroji. Kubudirira kwe bamboo papermaking kunoratidza kuti yekare Chinese papermaking tekinoroji yasvika padanho rakakura.
MuTang Dynasty, matekinoroji ekugadzira akadai sekuwedzera alum, kuwedzera glue, kuisa hupfu, kumwaya goridhe, uye kudhaya zvakabuda mushure meimwe mukugadzira mapepa, zvichiisa hwaro hwehunyanzvi hwekugadzira mapepa akasiyana siyana. Hunhu hwemapepa anogadzirwa huri kuwedzera nepamusoro, uye kune marudzi akawanda uye akawanda. Kubva kuTang Dynasty kuenda kuQing Dynasty, kuwedzera pamapepa akajairika, China yakagadzira mapepa ewakisi ane mavara akasiyana-siyana, goridhe rinotonhora, goridhe rakaiswa, ribvu, goridhe revhu nesirivheri pamwe nekupenda, mapepa ekarenda nemamwe mapepa anokosha, pamwe nemapepa akasiyana emupunga. , mapepa emadziro, mapepa emaruva, nezvimwewo. Kuita mapepa chinhu chinodiwa kuhupenyu hwetsika dzevanhu uye hupenyu hwezuva nezuva. Kugadzirwa uye kugadziridzwa kwepepa kwakapfuurawo nemuitiro wakashata.
Kwakabva Bamboo
Mubhuku rake rinonzi "Gomo", Liu Cixin akatsanangura imwe puraneti iri muchadenga chakaoma, achiidaidza kuti "bubble world". Nyika iyi yakanyatsopesana neNyika. Inzvimbo yedenderedzwa ine radius yemakiromita 3 000, yakakomberedzwa nematombo makuru akaturikidzana mumativi matatu. Mune mamwe mazwi, mu "bubble world", zvisinei kuti ndeipi nzira yaunoenda kumagumo, uchasangana nedombo gobvu madziro, uye dombo iri rusvingo rinotambanuka nekusingaperi kumativi ese, sebubble rakavigwa mune yakakura zvisingaperi yakasimba.
Iyi yekufungidzira "bubble world" ine hukama hwakashata nechadenga chedu chinozivikanwa nePasi, hupenyu hwakapesana zvachose.
Uye bamboo pachayo inewo zvinoreva "bubble world". Muviri wakakomberedzwa bamboo unoumba mhango, uye pamwe chete neakachinjika bamboo node, inoumba yakachena yemukati dumbu nzvimbo. Kuenzaniswa nemimwe miti yakasimba, bamboo zvakare i "bubble world". Yemazuva ano bamboo pulp bepa ipepa remazuva ano remba rakagadzirwa nemhandara bamboo pulp uye rakagadzirwa nemichina yepasirese yakazara otomatiki. Sezvo munda wezvigadzirwa zvezuva nezuva zvekugadzira uchibhadhara zvakanyanya uye zvakanyanya kutarisisa kune kushandiswa kwe bamboo pulp, vanhu vanonyanya kuda kuziva nezve hunhu uye nhoroondo ye bamboo bepa. Zvinonzi avo vanoshandisa bamboo vanofanira kuziva kwakabva bamboo.
Kutsvaga kumashure kune kwakabva bepa re bamboo, kune maonero maviri makuru munharaunda yezvidzidzo: imwe ndeyekuti bepa re bamboo rakatanga muJin Dynasty; imwe yacho ndeyekuti bepa re bamboo rakatanga muTang Dynasty. Bamboo pulp papermaking inoda yakakwira tekinoroji zvinodiwa uye yakaoma. Chete muTang Dynasty, apo tekinoroji yekugadzira mapepa yakagadziridzwa zvakanyanya, izvi zvaigona kuwanikwa, zvichiisa hwaro hwekuvandudzwa kukuru kwebepa remushenjere muRwiyo Rwenziyo.
Bamboo pulp mapepa ekugadzira maitiro
1. Mushenjere wakaomeswa nemhepo: sarudza mushenjere murefu uye mutete, cheka matavi nemashizha, cheka mushenjere kuita zvidimbu, woatakura kuenda nawo kuchivanze chemidziyo. Geza zvimedu zveshenjere nemvura yakachena, bvisa tsvina ine madhaka nejecha, wozozvitakura uende nazvo pachivanze chekututirana. Kuomeswa kwemhepo kwechisikigo kwemwedzi mitatu, bvisa mvura yakawandisa yekumira.
2. Six-pass screening: geza zvinhu zvakaomeswa nemhepo nemvura yakachena kakawanda mushure mekuburutsa kuti ubvise zvachose tsvina yakaita sedhaka, huruva, ganda remushenjere, wozvicheka kuita zvidimbu zveshenjere zvinosangana nezvinodiwa, wozopinda mudura. yekumira mushure me6 screenings.
3. Kupisa kwepamusoro-kupisa: bvisa lignin uye kwete-fiber zvikamu, tumira zvimedu zve bamboo kubva kune silo kusvika kune pre-steamer yekubika, wozoisa iyo yakakwirira-simba screw extruder ye extrusion yakasimba uye kudzvinyirira, wozopinda muchikamu chechipiri. pre-steamer yekubika, uye pakupedzisira pinda iyo 20-mita-yakakwira vertical steamer yemhando yepamusoro-tembiricha uye yakakwirira-kutsinhanisa kutsiva kubika. Wobva waiisa mushongwe yepulp kuitira kuchengetedza kupisa uye kubika.
4. Kudhonzera kwemuviri mubepa: Mapepa emapepa anodhonzwa nenzira dzemuviri mukati mekuita. Maitiro ekugadzira haakuvadzi kumuviri wemunhu, uye chigadzirwa chakapedzwa hachina masara emakemikari anokuvadza, ane hutano uye akachengeteka. Shandisa gasi rechisikigo panzvimbo pemafuta echinyakare kudzivirira kusvibiswa kwehutsi. Bvisa maitiro eku bleaching, chengetedza ruvara rwekutanga rwemiti yezvirimwa, dzikisa kushandiswa kwemvura yekugadzira, dzivirira kubuda kwemvura yetsvina yebleaching, uye chengetedza nharaunda.
Chekupedzisira, iyo yakasikwa ruvara pulp inosvinwa, yakaomeswa, yobva yachekwa kuita zvinoenderana nekurongedza, chekufambisa, kutengesa uye kushandisa.
Hunhu hwe bamboo pulp paper
Bamboo pulp bepa rakapfuma mu bamboo fiber, inova yakasikwa inorwisa mabhakitiriya, ruvara rwechisikigo uye isingawedzeri kwezvakatipoteredza ine hushamwari fiber inotorwa kubva mushenjere uchishandisa yakakosha maitiro. Iine huwandu hwakawanda hwekushandisa. Pakati pavo, bamboo ine bamboo Kun chikamu, ine antibacterial properties, uye huwandu hwekufa kwebhakitiriya hunogona kusvika kudarika 75% mukati maawa makumi maviri nemana.
Bamboo pulp bepa haringochengete chete kunaka kwemhepo kupinza uye kunyudzwa kwemvura kwe bamboo fiber, asi zvakare ine kuvandudzwa kwakanaka musimba remuviri.
nyika yangu yakadzika sango nzvimbo ishoma, asi bamboo zviwanikwa zvakapfuma kwazvo. Inonzi "sango rakadzika rechipiri". Yashi Pepa's bamboo fiber tissue inosarudza yekuzvarwa bamboo uye inoicheka pasi zvine musoro. Haisi kungokuvadza ecology chete, asiwo inobatsira pakuzvarwa patsva, uye inonyatsoita kutenderera kwegirinhi!
Yashi Pepa ragara richiomerera kune pfungwa yekuchengetedzwa kwezvakatipoteredza uye hutano, kugadzira yepamusoro-mhando uye inoshamwaridzana yekuzvarwa bamboo pulp bepa, inotsigira kuchengetedza kwezvakatipoteredza mabasa ehutano hweveruzhinji mukuita, achiomerera pakutsiva huni neshenjere, uye kusiya makomo akasvibira nemvura yakachena kuitira. ramangwana!
Zvinonyanya kusimbisa kusarudza Yashi bamboo pulp paper
Yashi Pepa's natural color bamboo fiber tissue inogara nhaka huchenjeri uye hunyanzvi hwakapfupikiswa nevanhu mukugadzira mapepa munhoroondo yeChinese, inotsvedzerera uye ine hushamwari hweganda.
Zvakanakira zveYashi Pepa's bamboo fiber tissue:
Yakapasa iyo fluorescent whitening agent bvunzo, hapana zvinokuvadza zvinowedzera
Yakachengeteka uye isingatsamwire
Yakapfava uye inoshamwaridzana neganda
Silky touch, inoderedza kuputika kweganda
Super kuoma, inogona kushandiswa yakanyorova kana yakaoma
