Makatoni oyera a paketi ya ndudu amafunikira kuuma kwakukulu, kukana kusweka, kusalala komanso kuyera. Pamwamba pamafunika kukhala lathyathyathya, osaloledwa kukhala ndi mikwingwirima, mawanga, tokhala, warping ndi mapindikidwe a m'badwo. Monga ndudu phukusi ndi woyera makatoni. The ntchito yaikulu ukonde mkulu-liwiro gravure makina osindikizira kusindikiza, kotero woyera makatoni mavuto index zofunika ndi mkulu. Kuthamanga kwamphamvu, komwe kumadziwikanso kuti mphamvu yamagetsi kapena mphamvu yamagetsi, imatanthawuza kuti ndizovuta kwambiri zomwe pepala lingathe kupirira panthawi yosweka, yofotokozedwa mu kN / m. Mkulu-liwiro gravure makina osindikizira kukoka masikono pepala, mkulu-liwiro kusindikiza kupirira mavuto aakulu, ngati chodabwitsa cha pafupipafupi yopuma pepala, ayenera kuchititsa stoppages pafupipafupi, kuchepetsa ntchito dzuwa, komanso kuonjezera imfa ya pepala.
Pali mitundu iwiri yamakatoni oyera a mapaketi a ndudu, imodzi ndi FBB (yellow core white cardboard) ndipo ina ndi SBS (white core white cardboard), FBB ndi SBS zomwe zingagwiritsidwe ntchito pa mapaketi a ndudu ndi makatoni oyera okutidwa mbali imodzi.
FBB imakhala ndi zigawo zitatu za zamkati, pamwamba ndi pansi zimagwiritsa ntchito zamkati zamatabwa za sulphate, ndipo pakatikati pake amagwiritsa ntchito mankhwala opangidwa ndi matabwa. Mbali yakutsogolo (mbali yosindikizira) imakutidwa ndi chophimba chomwe chimagwiritsidwa ntchito pogwiritsa ntchito squeegees awiri kapena atatu, pamene mbali yakumbuyo ilibe wosanjikiza. Popeza wosanjikiza wapakati amagwiritsa ntchito mankhwala ndi mechanically pansi nkhuni zamkati, amene ali ndi zokolola zambiri matabwa (85% mpaka 90%), kupanga ndalama ndi otsika, choncho mtengo wogulitsa chifukwa.FBB makatonindi otsika. Zamkatimu zimakhala ndi ulusi wautali komanso ulusi wabwino wocheperako ndi mitolo ya ulusi, zomwe zimapangitsa kuti pepala lomalizidwa bwino kwambiri, kotero kuti FBB ya galamala yomweyi imakhala yokhuthala kuposa SBS, yomwe nthawi zambiri imakhala ndi zigawo zitatu za zamkati, ndi sulfure- bleached nkhuni zamkati ntchito pa nkhope, pachimake, ndi kumbuyo zigawo. Kutsogolo ((mbali yosindikizira)) ndi yokutidwa, ndipo monga FBB imakutidwanso ndi ma squeegee awiri kapena atatu, pomwe mbali yakumbuyo ilibe wosanjikiza. Popeza pachimake wosanjikiza amagwiritsanso ntchito bleached sulfate nkhuni zamkati, ali ndi zoyera kwambiri choncho amatchedwa woyera pachimake woyera khadi. Panthawi imodzimodziyo, ulusi wa zamkati ndi wabwino, pepala ndi lolimba, ndipo SBS ndi yowonda kwambiri kuposa makulidwe a FBB a grammage yomweyo.
Khadi la ndudu, kapenamakatoni oyerakwa ndudu, ndi katoni yoyera yoyera yapamwamba kwambiri yomwe imagwiritsidwa ntchito makamaka popangira zida zokutira ndudu. Pepala lapaderali limakonzedwa ndikupangidwa bwino mwadongosolo lokhazikika, ndipo ntchito yake yayikulu ndikupatsa ndudu zonyamula zowoneka bwino, zaukhondo komanso zoteteza kunja. Monga gawo lofunikira lazinthu zafodya, khadi la ndudu silimangokwaniritsa zofunikira pakulongedza kwazinthu, komanso limazindikira kuwonekera kwachidziwitso chamtundu chifukwa cha chisamaliro chake chapadera komanso kuyenerera kusindikiza.
Mawonekedwe
1. Zinthu ndi kuchuluka kwake.
Khadi la ndudu lili ndi mlingo waukulu, nthawi zambiri pamwamba pa 200g/m2, zomwe zimatsimikizira makulidwe ndi mphamvu zokwanira zothandizira ndi kuteteza ndudu mkati.
Kapangidwe kake ka fiber ndi kofanana komanso kowuma, kopangidwa ndi zamkati zamatabwa zapamwamba kwambiri, ndikuwonjezera zodzaza ndi zomatira moyenera kuti zitsimikizire kuti pepalalo ndi lolimba komanso limagwira ntchito bwino.
2. Kupaka ndi kalendala.
Ndondomeko ya kalendala imapangitsa kuti pamwamba pake ikhale yosalala komanso yosalala, imapangitsa kuti pepala likhale lolimba komanso lonyezimira, ndipo limapangitsa kuti mapaketi a ndudu aziwoneka apamwamba kwambiri.
3. Physicochemical katundu.
Khadi la ndudu lili ndi kupindika kwabwino kwambiri komanso kukana kung'ambika, kuwonetsetsa kuti palibe kusweka pakulongedza mwachangu kwambiri. Imakhala ndi mayamwidwe abwino komanso kuyanika kwa inki, yomwe ndi yabwino kusindikiza mwachangu komanso kupewa kulowera kwa inki.
Imakwaniritsa zofunikira za malamulo otetezera chakudya, ilibe fungo ndipo ilibe zinthu zovulaza thupi la munthu, zomwe zimateteza chitetezo cha ogula.
4. Kuteteza chilengedwe ndi kudana ndi chinyengo.
Ndi chidziwitso chowonjezereka cha chitetezo cha chilengedwe, kupanga makadi a ndudu amakono kumakonda kugwiritsa ntchito zinthu zongowonjezedwanso ndikuchepetsa kuwononga chilengedwe.
Makhadi ena a ndudu apamwamba kwambiri amaphatikizanso njira zamakono zolimbana ndi kuba, monga zokutira zapadera, ulusi wamitundumitundu, mawonekedwe a laser, ndi zina zotero, kuti athane ndi vuto lalikulu lomwe likuchulukirachulukira la kuba.
Mapulogalamu
Kupaka m'mabokosi olimba: Kumagwiritsidwa ntchito popanga mitundu yosiyanasiyana ya mabokosi olimba a ndudu, wosanjikiza wamkati amathanso kupangidwa ndi zojambulazo za aluminiyamu ndi zida zina kuti awonjezere zotchinga. Paketi zofewa: Ngakhale ndizosowa, makhadi a ndudu amagwiritsidwanso ntchito ngati zomangira kapena zotsekera m'mapaketi ofewa a ndudu.
Chizindikiro: Pogwiritsa ntchito makina osindikizira apamwamba kwambiri komanso kapangidwe kake kapadera, makadi a ndudu amathandiza makampani afodya kuwonetsa mtundu wawo komanso kukulitsa mpikisano wamsika.
Zofunikira pazamalamulo ndi malamulo: Popeza kuti malamulo akuchulukirachulukira okhudza kuyika kwa fodya m'mayiko osiyanasiyana, makadi a ndudu akufunikanso kutsatira mfundo yakuti machenjezo a zaumoyo aoneke bwino komanso ovuta kuwasokoneza.
