Ukuthamba komkhiqizo wethishu, ukumunca, kanye nokusebenza kokuguqula kunqunywa kakhulu ngaphambi kokuba ufike endaweni yokubuyisela emuva. Kubathengi, umbuzo wangempela awukhona nje ukuthi i-roll yenziwe nge-virgin wood pulp, kodwa ukuthi imibiko yomhlinzeki iyafakazela ukuthi ingasebenza kahle futhi ihlangabezane nezindinganiso zemakethe eziqondiwe.Ukwakheka kwefayibha, i-GSM, ukukhanya, umswakama, ubukhulu bokugoqa, ukumuncwa, kanye nedatha yamandlakonke kuthonya isivuno, isikhathi sokungasebenzi, kanye nokungaguquguquki komkhiqizo oqediwe. Lo mhlahlandlela uchaza ukuthi yini okufanele iqinisekiswe amaqembu okuthenga kanye nobuchwepheshe ephepheni lokuchaza umqulu wabazali bethishu, ukuthi ungahumusha kanjani izinombolo ezibalulekile ezifana no-12–42 GSM kanye nomswakama ongu-4%–7%, nokuthi yiziphi iziphambeko zomzimba ezingaphazamisa ukuguqulwa.
Imininingwane Eyinhloko Yokuqinisekisa
Uma ufuna i-izicubu ze-pulp zokhuni oluyi-virgin, ukuqinisekisa imininingwane eyisisekelo kubalulekile ukuqinisekisa imisebenzi yokuguqula engenamthungo. Le miqulu emikhulu isebenza njengesisekelo seukukhiqizwa kwezicubuKungakhathaliseki ukuthi isikhungo sikhiqiza izicubu zobuso ezisezingeni eliphezulu noma imikhiqizo yokusula yezimboni, isisekelo sokufaka sinquma ikhwalithi yokugcina. Amaqembu okuthenga kumele aqinisekise izilinganiso ezithile emibikweni yabaphakeli ngaphambi kokukhipha i-oda lokuthenga.
Okuqukethwe kwe-Fiber, Ukukhanya, kanye ne-GSM
Isilinganiso sokuqala okufanele siqinisekiswe kunoma yimuphi umbiko womhlinzeki ukwakheka. Izicubu ezijwayelekile zekhwalithi ephezulu zidinga inhlanganisela elinganiswe kahle yezintambo eziqinile neziqinile zezinkuni ezithambile. Isilinganiso esifanele siyahlukahluka ngokuya ngokusetshenziswa kokugcina: i-pulp yezinkuni ezithambile inikeza amandla abalulekile okudonseka adingekayo ukuze umshini usebenze kahle futhiamathawula ezandla anzima, kuyilapho i-pulp yokhuni inegalelo ekuthambekeni nasekulungeni okukhulu kwezicubu zobuso. Kanye nokwakheka kwefayibha, abathengi kumele bahlole isisindo esiyisisekelo, esivame ukuba phakathi kuka-12 no-42 GSM kuye ngokuthi uhlelo lokusebenza luyi-izicubu zobuso ezithambilenoma i-washer eqinile.
Ukukhanya kungenye into ebalulekile ekukhangeni kwabathengi ezimakethe zobukhazikhazi nezokungenisa izihambi. Imibiko yelabhorethri yamazinga e-bleached virgin kufanele iqinisekise izinga lokukhanya kwe-ISO phakathi kuka-86% no-90%. Ngakolunye uhlangothi, i-pulp ye-virgin engacwebezeli ivame ukusetshenziswa ezinhlelweni ezithile zezimboni nezokudla, ezinezidingo zokukhanya ezihluke kakhulu. Uma indawo ithola izimpahla.imiqulu yabazali eyenziwe ngokwezifiso, ukuqinisekisa ukuthi lezi zilinganiso zokukhanya zinembile kuzogcina ukubukeka okufiselekayo ezimpahleni eziqediwe.
