Kwimveliso yephepha yanamhlanje, eyona nto isetyenzisiweyo ekrwada yinkunkuma yephepha kunye ne-pulp yentombi, kodwa ngamanye amaxesha inkunkuma yephepha kunye ne-virgin pulp ayifumaneki kwindawo ethile, kunzima ukufumana okanye kuyindleko kakhulu ukuyithenga, kulo mzekelo, umvelisi unokuqwalasela ukuba sebenzisa umququ wengqolowa njengento ekrwada ukuvelisa iphepha, umququ wengqolowa yimveliso eqhelekileyo yezolimo, ekulula ukuyifumana, eninzi ngokwemali kwaye inexabiso eliphantsi.
Xa kuthelekiswa nefayibha yomthi, umququ wengqolowa uba crispy kwaye ubuthathaka, akukho lula ukwenza ibleach emhlophe, ngoko ke kwiimeko ezininzi, umququ wengqolowa usetyenziswa kakhulu ukuvelisa iphepha elivunguzayo okanye amazinki. i-pulp enyulu okanye inkunkuma yephepha ukuvelisa iphepha elisezantsi elinomgangatho ophantsi okanye iphepha leofisi, kodwa iphepha eligubhayo okanye iphepha elimdaka lithathwa njengelona mveliso lithandwayo, kuba inkqubo yemveliso ilula kakhulu kwaye iindleko zemveliso zincinci.
Ukuvelisa iphepha, umququ wengqolowa kufuneka usikwe kuqala, ubude be 20-40mm bukhethwa, kulula ngakumbi ukuba umququ udluliselwe okanye uxutywe nemichiza yokupheka, umatshini wokusika ingqolowa uyacelwa ukuba wenze umsebenzi, kodwa ngotshintsho ishishini lezolimo lwanamhlanje, ingqolowa idla ngokuvunwa ngoomatshini, kulo mzekelo, umatshini wokusika awuthathwa njengoyimfuneko.Emva kokusika, umququ wengqolowa uya kudluliselwa ukuxuba kunye neekhemikhali zokupheka, inkqubo yokupheka i-caustic soda isetyenziswa ngokuqhelekileyo kule nkqubo, ukunciphisa iindleko zokupheka, amanzi amatye e-lime nawo angaqwalaselwa.Emva kokuba umququ wengqolowa uxutywe kakuhle kunye neekhemikhali zokupheka, uya kuhanjiswa kwi-digester ye-spherical okanye i-pool yokupheka ephantsi komhlaba, ukupheka okuncinci kwezinto eziluhlaza, i-pool yokupheka ephantsi komhlaba iyacetyiswa, ukwakhiwa komsebenzi we-civil, iindleko ezincinci, kodwa ukusebenza okuphantsi.Ukufumana umthamo ophezulu wemveliso, kufuneka kuthathelwe ingqalelo ukusebenzisa i-digester engqukuva okanye isixhobo sokupheka esidibeneyo, inzuzo kukupheka ngokufanelekileyo, kodwa ke, iindleko zezixhobo ziya kuba phezulu kakhulu.I-pool yokupheka ephantsi komhlaba okanye i-digester spherical digester idityaniswe nomphunga oshushu, kunye nokunyuka kweqondo lokushisa kwisitya okanye itanki kunye nokudibanisa kwe-agent yokupheka, i-lignin kunye nefayibha ziya kwahlulwa kunye.Emva kwenkqubo yokupheka, umququ wengqolowa uya kothulwa kwisitya sokupheka okanye itanki yokupheka ukuya kumgqomo wokuvuthela okanye itanki yentlenga esele ilungele ukukhupha ifayibha, umatshini osetyenziswa ngokuxhaphakileyo ngumatshini wokwenza ibleaching, umatshini wokuhlamba ipulp onesantya esiphezulu okanye i-bivis extruder, kude kube ngoko umququ wengqolowa. ifayibha iya kukhutshwa ngokupheleleyo, emva kwenkqubo yokucocwa nokuhlolwa, iya kusetyenziselwa ukwenza iphepha.Ngaphandle kwemveliso yephepha, i-wheat straw fiber ingasetyenziselwa ukubumba itreyi yeplanga okanye ukubumba itreyi yeqanda.
