Kwimveliso yanamhlanje yephepha, izinto ezisetyenziswa kakhulu ziphepha elilahliweyo kunye ne-virgin pulp, kodwa ngamanye amaxesha iphepha elilahliweyo kunye ne-virgin pulp azifumaneki kwenye indawo, kunzima ukuzifumana okanye zibiza kakhulu ukuzithenga, kule meko, umvelisi angacinga ngokusebenzisa i-wheat straw njengezinto eziluhlaza ukuvelisa iphepha, i-wheat straw sisiphumo esiqhelekileyo sezolimo, okulula ukuyifumana, ininzi kakhulu kwaye ixabisa kancinci.
Xa kuthelekiswa nefayibha yomthi, ifayibha yengca yengqolowa iqhoqhoqho ngakumbi kwaye ibuthathaka, akulula ukuyixuba ibe mhlophe, ngoko ke kwiimeko ezininzi, ingca yengqolowa isetyenziswa kakhulu ukuvelisa iphepha lokugquma okanye iphepha eligobileyo, ezinye iifektri zephepha zikwaxuba i-wheat straw pulp kunye ne-virgin pulp okanye iphepha elingasetyenziswanga ukuvelisa iphepha lethishu elikumgangatho ophantsi okanye iphepha leofisi, kodwa iphepha lokugquma okanye iphepha eligobileyo lithathwa njengeyona mveliso ithandwayo, kuba inkqubo yemveliso ilula kakhulu kwaye iindleko zemveliso ziphantsi.
Ukuze kuveliswe iphepha, kufuneka kuqale kusikwe ingca yengqolowa, ubude obuyi-20-40mm buyakhethwa, kulula ngakumbi ukuba ingca idluliselwe okanye ixutywe neekhemikhali zokupheka, umatshini wokusika ingca yengqolowa ucelwe ukuba wenze umsebenzi, kodwa ngotshintsho lweshishini lezolimo lanamhlanje, ingqolowa idla ngokuvunwa ngoomatshini, kule meko, umatshini wokusika awuthathwa njengoyimfuneko. Emva kokusika, ingca yengqolowa iya kudluliselwa ukuze ixutywe neekhemikhali zokupheka, inkqubo yokupheka i-caustic soda isetyenziswa kakhulu kule nkqubo, ukunciphisa iindleko zokupheka, amanzi elitye lelayimu nawo anokuqwalaselwa. Emva kokuba ingca yengqolowa ixutywe kakuhle neekhemikhali zokupheka, iya kudluliselwa kwi-spherical digester okanye edamini lokupheka elingaphantsi komhlaba, kucetyiswa ukupheka izinto eziluhlaza ezincinci, idama lokupheka elingaphantsi komhlaba, ukwakhiwa komsebenzi wokwakha, iindleko ezincinci, kodwa ukusebenza kakuhle okuphantsi. Ukuze kubekho amandla aphezulu emveliso, kufuneka kucingwe ukusebenzisa i-spherical digester okanye isixhobo sokupheka esikufutshane, inzuzo kukusebenza kakuhle kokupheka, kodwa ewe, iindleko zezixhobo ziya kuba phezulu. Ichibi lokupheka elingaphantsi komhlaba okanye i-spherical digester lidibene nomphunga oshushu, kunye nokunyuka kobushushu kwisitya okanye itanki kunye nokudibanisa i-agent yokupheka, i-lignin kunye nefayibha ziya kwahlulwa. Emva kwenkqubo yokupheka, ingca yengqolowa iya kuthululwa kwisitya sokupheka okanye itanki yokupheka iye kwi-blow bin okanye itanki ye-sediment elungele ukukhupha ifayibha, umatshini osetyenziswa rhoqo ngumatshini woku-bleaching, umatshini wokuhlamba i-pulp okhawulezayo okanye i-bivis extruder, de kube ngoko i-wheat straw fiber iya kukhutshwa ngokupheleleyo, emva kwenkqubo yokucocwa nokuhluzwa, iya kusetyenziselwa ukwenza iphepha. Ngaphandle kokuveliswa kwephepha, i-wheat straw fiber ingasetyenziselwa ukubumba itreyi yomthi okanye ukubumba itreyi yamaqanda.
