Kuyamba kwa wamba chitsulo luso njiru kupopera mbewu mankhwalawa
Njira yamtundu wachitsulo imatha kugawidwa pafupifupi mtundu wamtundu wa extrusion, njira yophatikizika yotulutsa, njira yokutira filimu ndi kuluma kovomerezeka.
1) Njira Yowonjezera Mbiri Yamtundu.Imadziwikanso kuti njira ya extrusion ya thupi lonse.Onjezani chilinganizo chachitsulo chachitsulo ndikufinyani mawonekedwe amtundu mwachindunji kudzera mu extruder.Ubwino wake ndikuti mankhwala omalizidwa amatulutsidwa pa extruder yapachiyambi ndi mtengo wotsika;mbiri kukana nyengo ndi osauka, zovuta kukwaniritsa zofunika m'nyumba ndi kunja kukongoletsa kwenikweni.
2) Kuphatikiza Co-extrusion.Mbiriyo imafinyidwa ndi zitsulo zachitsulo, kuphatikizapo wosanjikiza wazinthu zamtundu.Zida zamtundu, kaya chitsulo, zimafunikira makamu awiri otulutsa (cone bar 60 kapena 58, screw single 30) kuti akwaniritse.Zoumba zophatikiza ziyenera kugwiritsidwa ntchito popanga mbiri.Kapangidwe kake ndikuphatikiza ma profailo ndi mitundu kuchokera kumayendedwe awiri osiyanasiyana kupita ku nkhungu imodzi musanachoke mu nkhungu.Makhalidwe a njira iyi ndi: popanga, kufunikira kokhala ndi chosakaniza chotentha ndi chozizira kapena chowumitsira ndi zipangizo zina, zovuta zowonongeka zakuthupi, ndondomeko yopangira zovuta, mtengo wapamwamba wa mafilimu, ndalama zambiri.
3) Njira Yopaka.Zitsulo zachitsulo zinkatenthedwa ndikuzikulungidwa mwamakina ndikumangirira pamwamba pazitsulo zachitsulo posindikiza filimu yamtundu ndi zomatira.Makhalidwe ake ndi: ndondomeko yopanga iyenera kuchitidwa pamzere wa msonkhano, iyenera kusankha filimu yabwino ndi zomatira zomwe zimatumizidwa kunja, mtengo wapamwamba;yomanga mtundu filimu kuwonongeka sangathe kukonzedwa.
4) Njira Yopopera Pamwamba.Utoto wamtundu ukhoza kupakidwa mofanana pamtunda wowonekera wa njanji yachitsulo, ukhoza kupopera mbali imodzi, kapena kupopera mbali ziwiri.Makhalidwe ake amadziwika ndi mitundu yosiyanasiyana, yosinthika komanso yabwino kupanga ndi zomangamanga.
