Pali mitundu yambiri ya zida zoyikapo, palibe zabwino, zokhazokha zokhazokha.Pakati pawo, corrugated ma CD bokosi ndi chimodzi mwazinthu zosankhidwa kwambiri.Chifukwa cha mapangidwe apadera a pepala lamalata, chiwembu chopepuka komanso cholimba cha ma CD chingapangidwe.
Kodi malata ndi chiyani?
Bolodi yamalata, yomwe imadziwikanso kuti corrugated fiber board, imapangidwa ndi ulusi wopepuka wotalikirapo, womwe umapezeka kuchokera ku ulusi waiwisi kapena matabwa ogwiritsidwa ntchito ndi zinthu zina.
Makatoni opangidwa ndi malata amapangidwa kuchokera ku chinthu chimodzi kapena zingapo (zotchedwa "base paper" kapena "corrugates") zomwe zimamangiriridwa ku pepala limodzi kapena angapo a "makatoni" ndi zomatira zomwe zimagwiritsidwa ntchito pamwamba pa corrugates.
Chiwerengero cha pepala la nkhope ndi pepala lalikulu la bolodi lamalata limatsimikizira gulu: mbali imodzi ya corrugated, wosanjikiza wosanjikiza, wosanjikiza kawiri, wosanjikiza katatu, ndi zina zotero.Malinga ndi ripple imagawidwa kukhala: A,B,C,E,F malata.Ma corrugations awa amatchulidwa molingana ndi kukula, kutalika ndi kuchuluka kwa ma ripples.
Single layer corrugated nthawi zambiri amagwiritsidwa ntchito mu A, B, C corrugated, BC corrugated ndi imodzi mwama board odziwika kwambiri.Magawo atatu a corrugations, okhala ndi ACC corrugations, ABA corrugations ndi magulu ena, amagwiritsidwa ntchito nthawi zambiri pakulongedza katundu wolemera, kutengera wopanga ndi malo.
Zoyika pamalata zimatha kubwera mosiyanasiyana, mawonekedwe ndi makulidwe ake malinga ndi ntchito.Mabungwe apadziko lonse lapansi, monga FEFCO ku Europe, ali ndi mapepala okhala ndi malata.
Mitundu yosiyanasiyana ya makatoni
Ngakhale kuti mabokosi ambiri a malata amawoneka ofanana, amapangidwa ndi mitundu yosiyanasiyana ya zipangizo, zomwe zingakhudze kwambiri makhalidwe awo ndi ntchito zawo.Mitundu ingapo ya makatoni ndi awa:
Kraft paperboard
Mapepala a Kraft amakhala ndi osachepera 70-80% a ulusi woyambirira wamankhwala.Amatengedwa kuti ndi zida zapamwamba kwambiri, zolimba kwambiri komanso zamphamvu, zokhala ndi malo osalala.Mapepala ambiri a kraft amapangidwa kuchokera ku softwood zamkati, pamene ena amapangidwa kuchokera ku birch ndi zina zolimba zamatabwa.Mapepala a Kraft amatha kugawidwa m'magulu angapo malinga ndi mtundu wawo:
Mtundu wa bulauni wa bulauni wa pepala la brown kraft udzasiyana, kutengera ulusi, pulping process, ndi malo obzala.
Pepala loyera la kraft ndilolimba kwambiri komanso lamtengo wapatali.
Grey kraft paper board, yomwe imadziwikanso kuti oyster paper board, ndi yofanana ndi bolodi loyera la kraft, koma imakhala ndi mawonekedwe osiyanasiyana.
Mabokosi a mapepala a bleached kraft amawoneka mwachibadwa, koma amadutsa gawo lina lowonjezera.Iwo sali amphamvu ngati mapepala osakanizidwa.
Pepala la birch veneer kraft limapangidwa ndi zinthu zofanana ndi pepala loyera la veneer kraft, koma lokhala ndi bleached pamwamba.Izi zimachepetsa chilengedwe chonse cha makatoni.
Khadi la ng'ombe lotsanzira
Mphamvu ya ng'ombe ya ng'ombe ya ng'ombe ya ng'ombe ndi yofanana ndi bolodi ya kraft, chifukwa yoyamba ili ndi ulusi wochuluka wopangidwanso.Ndikofunika kuzindikira kuti makatoni otsanzira a ng'ombe a bulauni amatha kugawidwa m'magulu osiyanasiyana, ngakhale kuti izi zimasiyana malinga ndi dziko ndi dera.
Wamba makatoni
Makatoni wamba sakhala wamba ngati pepala la kraft kapena bulauni kutsanzira bovine cardstock.Nthawi zambiri amapangidwa kuchokera ku zinthu zosayendetsedwa bwino zobwezerezedwanso, zomwe zikutanthauza kuti sizili zapamwamba kwambiri ndipo sizimapereka ntchito yofananira ndi mitundu ina ya makatoni.Pali mitundu itatu ya makatoni wamba:
bleached cardboard,kawirikawiri woyera.
White cardboard,pogwiritsa ntchito laminated bleached makatoni, amawoneka ofanana ndi bleached cardboard, ngakhale kuti ndi otsika mtengo.
Gray cardboard,nthawi zambiri amagwiritsidwa ntchito ngati pepala loyambira.
Palinso zinthu zina zofunika kuziganizira.Mwachitsanzo, matumba a malata amatha kukhala ndi magawo amodzi, awiri kapena atatu.Zigawo zambiri, phukusili lidzakhala lamphamvu komanso lolimba, koma nthawi zambiri limakhala lokwera mtengo.
Kodi tiyenera kuganizira chiyani posankha malata?
Nthawi zambiri, mapaketi a malata ndiye phukusi labwino kwambiri.Choyamba, chifukwa ndi 100% yobwezeretsanso, ndi chisankho chabwino kwa makampani osamala zachilengedwe, makamaka popeza kukhazikika kukukhala kofunika kwambiri kwa mabizinesi ochulukirachulukira.
Kupaka pamalata kumakhalanso ndi mawonekedwe akusintha.Mutha kusintha mtundu wa makatoni, zomatira zomwe zimagwiritsidwa ntchito komanso kukula kwa corrugator.Mwachitsanzo, zoyikapo malata zitha kukhala ndi nsanjika yoletsa moto wowonjezedwapo kuti igwiritsidwe ntchito ponyamula zinthu zoyaka kapena zosamva chinyezi zomwe zimakumana ndi chinyezi chambiri kapena kusiyanasiyana kwa kutentha.
Kulongedza kwamtunduwu kumakhala kolimba kwambiri chifukwa cha kulemera kwake ndipo kumatha kuteteza zinthu zosalimba panthawi yamayendedwe.Zogulitsa zimakhala zodzaza pakati pa mapepala a malata omwe ali olimba kuti athe kupirira kupanikizika kapena kugwedezeka.Zopakirazi zimatha kuteteza zinthu kuti zisagwere ndipo zimatha kupirira kugwedezeka kwakukulu.
Pomaliza, zinthuzo ndizokwera mtengo kwambiri.Ndi imodzi mwazinthu zotsika mtengo kwambiri zomwe zilipo ndipo, motero, ndi chisankho chabwino kwa iwo omwe akufuna kuchepetsa mtengo wolongedza popanda kusokoneza chitetezo chazinthu.
