Urupapuro rwerekana ububengerane ni ijanisha ryurumuri rwubururu urupapuro rugaragaza kumuraba mwiza wa 457 nm, upimye muburyo bwa optique ISO 12625-7 hamwe na D65 yamurika na 10 ° indorerezi. Nibintu bikwirakwiza ubururu, bisobanurwa na ISO 2470 na ISO 2469, kandi bisomwa neza kuri 0.05% . Umucyo ntabwo ari kimwe no kwera: umucyo ukoresha uburebure bumwe bwubururu, mugihe CIE yera itanga amanota yose agaragara, kandi opacite (ISO 12625-16) ipima umubare wimpapuro zerekana.
Umucyo ugereranya uburyo urupapuro rwera rugaragara ku gipimo cyubururu-cyera. Igikoresho kiyobora urumuri ku burebure bwa 457 nm hamwe na kimwe cya kabiri cyagutse cya 44 nm , hanyuma gipima ikwirakwizwa rya diffuse ugereranije na kalibibisanzwe. Ibisubizo bigaragazwa nkijanisha, mubisanzwe bivugwa kuri 0.05%.
Kuberako ibipimo byicaye mukarere k'ubururu, byumva umuhondo no kuri lignine isigaye cyangwa ibara. Umubare munini usobanura bluer, urupapuro rworoshye; umubare muto bisobanura ijwi risusurutse, risanzwe.
Ibisabwa: ingero zingana na 23 ° C na 50% RH (ISO 187).
Igikoresho cya geometrie: spekitifotometero / ibara ryerekana ikurikira diffuse / 0 ° geometrie ya ISO 2469.
Kumurika no kwitegereza: ibara n'umweru ukoreshe D65 kumanywa hamwe na 10 ° indorerezi munsi ya ISO 12625-7.
Kugaragaza ubururu: agaciro ka 457 nm kibarwa kuri ISO 2470.
Calibration: igikoresho gishyizwe mubipimo byemewe, kandi ibyasomwe bivugwa kuri 0.05%.
Aya magambo atatu optique akunze kwitiranya ariko apima ibintu bitandukanye.

CIE yera isuzuma urwego rwose rugaragara kuruta umurongo umwe w'ubururu, bityo bihuye neza nuburyo abantu babona ibicuruzwa 'byera '. Irashobora gutandukanya umweru utagira aho ubogamiye nubururu bwerurutse cyangwa icyatsi-cyera cyera gishobora gusangira numero yumucyo.
Amahirwe ni igipimo cyo gukwirakwiza diffuse hejuru yumukara inyuma kuri hejuru yimpapuro yera inyuma, bigaragazwa nkijanisha. Irakubwira niba icapiro cyangwa ply yerekana byerekana. Igitabo cya 2024 cya ISO 12625-16 gisobanura uburyo bwo gusubiza inyuma impapuro, uburyo bwo kwerekana ibintu. Ubushobozi buhanitse bwibintu byanditseho napkins hamwe nibicuruzwa byinshi.
Ubwoko bwa pulp: bwakuweho inkumi kraft pulp igera kumucyo mwinshi; fibre idahumanye cyangwa yongeye gukoreshwa muri rusange ni hasi kandi irahinduka.
Bleaching and optique yamurika (OBAs): OBAs ikurura UV ikanasohora urumuri rwubururu, ikazamura umucyo wapimye.
Amazi no gutunganya isuku: kwanduza cyangwa ibara risigaye bigabanya gusoma.
Gusaza no kubika: ubushyuhe, urumuri nubushuhe birashobora gutera umuhondo mugihe.
Guhitamo fibre: fibre ngufi ya fibre iteza imbere no kuringaniza, igafasha gusoma neza.
Urupapuro rusanzwe, ruto-OBA ntirukoreshwa nkana kugirango rumurikwe kandi rukundwa kumurongo wambere kandi woroshye-uruhu. Umucyo rero ni intego yo kwerekana, ntabwo ari agaciro ko gusunika hejuru bishoboka.
HUAXIN ipima imiterere ya optique munsi ya ISO 12625-7 hamwe na opacite munsi ya ISO 12625-16 , hamwe na grammage (Igice cya 6), umubyimba (Igice cya 3), uburakari (Igice cya 4/5) no kwinjizwa (Igice cya 8). Ubugari bwa mm 200-22850 mm , GSM 11-42 g / m² , diameter igera kuri mm 1150 na mm 76 (3 in) , hamwe nubushuhe kuri 4-7% . Igikoresho cyuzuye gifite reel 26 / toni 12–13.
Ni ubuhe buryo busanzwe bwo kumurika impapuro? Ubucyo bupimirwa kuri ISO 12625-7, buvuga ISO 2470 na ISO 2469.Ni ikintu cyerekana ikwirakwizwa ry'ubururu ku burebure bwa 457 nm, byavuzwe kuri 0,05%, hamwe n'ibara n'umweru byapimwe munsi ya D65 hamwe na 10 °.
Umucyo ni kimwe no kwera? Oya. Ubwiza bupima kwigaragaza kuri 457 nm yubururu bwubururu, mugihe CIE yera isuzuma ibintu byose bigaragara. Impapuro ebyiri zirashobora kugira umucyo usa ariko zisa zitandukanye muri cyera cyangwa muri rusange.
Ubusembwa bwa tissue ni iki kandi ni ubuhe buryo bukubiyemo? Amahirwe apima uburyo impapuro zanga kwerekana-ukoresheje, ukoresheje diffuse refleks hejuru yimpapuro. Itwikiriwe na ISO 12625-16 (integuro ya 2024) kandi ni ingenzi kubice byacapwe kandi byinshi.
Ibikoresho byiza byo kumurika byongera umucyo? Yego. OBAs ikurura urumuri ultraviolet ikanatanga urumuri rwubururu, ikazamura umucyo wapimwe na CIE yera. Ibicuruzwa bisanzwe, bike-OBA byerekanwe kumurongo wo hasi kugirango byorohe, bitagaragara.
