Kugwiritsa ntchito High Retention Starch mu Cultural Paper Production

IP Sun Paper's PM23# makina makamaka amapanga mapepala azikhalidwe, kuphatikizapepala losindikiza la offset ndikope pepala , ndi kutulutsa kwapachaka kwa matani oposa 300,000. Makinawa ali ndi kalendala ya lamba wachitsulo, yomwe ili ndi zabwino zambiri pakuwongolera kusalala.

Kuchuluka kwa zodzaza kumawonjezeredwa pamapepala panthawi yopanga. Zomwe zimagwiritsidwa ntchito nthawi zambiri zodzaza mapepala ndi calcium carbonate, talc, kaolin, etc. Zodzaza mapepala monga calcium carbonate ndi zigawo zomwe zili ndi mapepala akuluakulu kupatulapo fiber, zimagwiritsidwa ntchito kwambiri chifukwa cha mtengo wake wotsika, kuchepetsa kuchuluka kwa mapepala. CHIKWANGWANI, kuchepetsa mtengo kupanga, pamene kuwongolera kusalala ndi permeability mpweya pepala; kukonza mawonekedwe a kuwala (kuyera, kuwala ndi gloss), ntchito yosindikiza ndi kulemba ntchito ya pepala.

Komabe, mutatha kuwonjezera zodzaza, chifukwa cha tinthu tating'onoting'ono tating'onoting'ono komanso malo akulu enieni, kudzaza kwachikhalidwe kumalepheretsa kulumikizana kwa haidrojeni pakati pa ulusi ndikuchepetsa mphamvu yapepala . Zodzaza zambiri zikamawonjezeredwa popanga, mphamvu yolumikizirana pakati pa ulusi mu pepala imakhudzidwa, ndipo m'pamenenso kuchepa kwa mphamvu zamapepala kumachepa. Kuphatikiza apo, ngakhale kuwonjezera zodzaza pamapepala kumatha kupititsa patsogolo kusefera kwamadzi pagawo la waya ndikuwonjezera kuuma kwa pepala lonyowa, koma kuchuluka kwa zodzaza zomwe zili mufiriji nthawi zambiri kumabweretsa kuchepa kwa kusungidwa kwa zodzaza panthawi yosefera madzi, kulephera kwa makina a pepala ndi zovuta zina. Zodzaza kwambiri zidzachepetsanso mphamvu ya pamwamba pa pepala, zomwe zimapangitsa kuti lint ndi kutaya ufa pakagwiritsidwe ntchito kwa pepala lomalizidwa.

Kuti muchepetse thupipepala lachikhalidwemtengo wopanga,IP Sun Paper mwapadera adagwirizana ndi American Special Mining Company kuti akhazikitse zida zosungirako wowuma kwambiri za gelatinization. Choyamba, wowuma ndi gelatinized mu thanki madzi ofunda, ndiyeno kusakaniza filler ndi anawonjezera choyambirira filler kuwonjezera mfundo. Zotsatira zikuwonetsa kuti pafupifupi 2 kg ya wowuma imawonjezedwa pa tani ya pepala, kuchuluka kwa wowuma muzamkati yonyowa kumachepetsedwa ndi pafupifupi 2 kg, phulusa limatha kuchulukitsidwa ndi 1.5%, kusungidwa kwadongosolo kumakula kwambiri, ndipo kuchuluka kwa zowonjezera kumachepetsedwa bwino; chiwerengero cha mphamvu sichinachepe kwambiri. Komabe, zimakhala ndi zotsatirapo zoipa pa kuchepa kwa madzi m'thupi la makina a pepala, ndipo zidzachititsaenamavuto monga kukakamira pa silinda.
