Ukusetyenziswa kwe-diatomite powder ekwenzeni iphepha kufuna ukucutshungulwa okukhethekileyo okulungiselelwe ngokweemfuno zoshishino. I-ore ye-diatomite eluhlaza ihlanjwa ngononophelo ukuze kususwe ungcoliseko lodongwe nesanti. Emva koko, yomiswa kancinci kumaqondo obushushu aqala kwi-100-120°C ukuze kulondolozwe isakhiwo sayo esibalulekileyo esineembobo. Emva koko iinkqubo zokusila ziyasetyenziswa ukuvelisa i-powder enobukhulu bee-particle obuphakathi kwe-5-30 μm. Ii-particles ezincinci, eziqhele ukuba kwi-5-15 μm, zisetyenziswa njenge-pigments zokugquma ezisebenzayo kwiphepha lokuprinta elikhazimlayo, ngelixa ii-particles ezinkulu (20-30 μm) zisebenza njengezizalisi ezisebenzayo ekubhaleni nasekupaketheni iphepha. Iindidi ezithile ze-diatomite powder ziphathwa nge-cationic polymers ukuphucula ukuhambelana nee-cellulose fibers, ukuqinisekisa ukusasazeka okufanayo kwi-pulp matrix.

Njengesigcwalisi sephepha, i-diatomite powder idlula ezinye iindlela zemveli ezifana ne-calcium carbonate (CaCO₃) okanye i-kaolin kwiinkalo ezininzi. Indalo yayo yokuba neembobo ivumela amandla aphezulu okusasazeka kokukhanya, okwandisa kakhulu ukungabonakali kwephepha ngaphandle kokunyuka kobunzima besiseko ngaxeshanye. Kwimveliso yephepha lokuprinta, ukufaka i-10-15% ye-pulp yomthi nge-diatomite powder endaweni ye-10-15% yokungabonakali kwe-TAPPI. Oku kuvumela abenzi bephepha ukuba banciphise ukusetyenziswa kwe-pulp, ngaloo ndlela benegalelo ekunciphiseni ukugawulwa kwamahlathi kunye nokonga iindleko. Umzekelo, umatshini wephepha waseFinland ufake i-8% ye-diatomite powder kwifomyula yawo yephepha lokuprinta, nto leyo ebangele ukwanda kokungabonakali ukusuka kwi-88% ukuya kwi-96%, ukwehla kwe-12% ekusetyenzisweni kwe-pulp, kunye nokwehla kwe-18% kwiindleko zezinto eziluhlaza. Ukongeza, ubumhlophe obukhulu be-diatomite powder (ixabiso le-L* ≥92) kuqinisekisa ukuba iphepha ligcina inkangeleko eqaqambileyo, ecocekileyo, ebalulekileyo ekuveliseni umbhalo osemgangathweni ophezulu kunye nemifanekiso.

I-Diatomite powder ikwajongana nomda oqhelekileyo we-fillers zemveli ngokuphucula amandla oomatshini ephepha. Ulwakhiwo lwayo olunemingxuma lwenza kube lula ukubopha kakuhle phakathi kweefayibha ze-cellulose, zisebenza njenge "bridges" xa zifakwe kwi-pulp. Xa kuthelekiswa nephepha elizaliswe yi-CaCO₃, i-diatomite powder inokunyusa amandla okutsalwa nge-8-12% kwaye ikrazule ngamandla nge-10-15%. Le propati ixabiseke kakhulu kwiphepha lokupakisha, ekufuneka linyamezele ukuphathwa nokuthuthwa okungqongqo. Umzekelo, umenzi wephepha lokupakisha waseTshayina, ufumene ukuphucuka okuphawulekayo kumandla okuqhuma ukusuka kwi-2.5 kPa·m²/g ukuya kwi-3.2 kPa·m²/g ngokufaka i-12% ye-diatomite powder kwifomyula yayo yephepha ebotshelelweyo, okwenza iphepha likwazi ukuxhasa imithwalo enzima ngaphandle kokusilela.

Ukuprintwa yenye indawo apho i-diatomite powder igqwesa khona. Njenge-pigment yokugquma, idala umphezulu ogudileyo nohambelanayo ophucula ukunamathela kwe-inki kunye nokuveliswa kwamachaphaza. Kwiphepha elingenamthi ogqunyiweyo, elisetyenziswa kakhulu kwiimagazini nakwiikhathalogu, ukugquma okusekelwe kwi-diatomite powder kubonisa uburhabaxa bomphezulu (Ra) obuyi-0.5-0.8 μm, xa kuthelekiswa ne-1.0-1.2 μm yokugquma okusekwe kwi-kaolin. Lo mphezulu uthambileyo uphumela kumachaphaza okuprinta abukhali, ukopha kwe-inki okunciphileyo, kunye nokuqaqamba kombala okuphuculweyo. Uvavanyo lweshishini lokuprinta lubonisa ukuba iphepha eligqunywe yi-diatomite powder lifumana inzuzo yamachaphaza engama-90-95%, xa kuthelekiswa ne-80-85% yephepha eligqunywe ngokwesiko. Ngaphezu koko, isakhiwo esinemingxuma se-diatomite powder sifunxa ngokufanelekileyo i-inki engaphezulu, sinciphisa ixesha lokomisa ngama-20-25% kwaye ngaloo ndlela siphucula ukusebenza kakuhle kweprinting press kwaye sinciphise imiqobo yemveliso.

Iingenelo zokusingqongileyo ze-diatomite powder ekwenzeni iphepha zinkulu kakhulu. Ngokunciphisa iimfuno ze-pulp, kunciphisa ukusetyenziswa kwamandla kunye nokukhutshwa kwegesi ye-greenhouse ehambelana nemveliso ye-pulp, okubandakanya ukugawulwa kwemithi okunzulu, ukuthuthwa, kunye nokulungiswa kweekhemikhali. Iifektri zephepha ezisebenzisa i-10% ye-diatomite powder zixela ukwehla kwe-CO₂ ngo-10-12%. Ngokungafaniyo nezizalisi zokwenziwa ezinokukhupha ii-microplastics kwindalo esingqongileyo, i-diatomite powder iyabola kwaye ayinatyhefu. Unyango lwamanzi amdaka lwenziwa lula nakwiifektri kusetyenziswa i-diatomite powder, njengoko i-powder ingasuswa nge-sedimentation kwaye isetyenziswe kwakhona kwiimveliso zephepha ezikumgangatho ophantsi, nto leyo enciphisa ukuveliswa kwenkunkuma.

Kwizicelo zephepha ezikhethekileyo, i-diatomite powder inika iipropati ezizodwa zokusebenza. Kwiphepha lokupakisha elingangeni mafutha, elisetyenziswa kakhulu ekutyeni okukhawulezayo kunye nezidlo ezikhawulezayo, isakhiwo salo esineembobo senza umqobo osebenzayo ngokuchasene ne-grisi, obonelela ngenye indlela ezinzileyo kuneengubo zokwenziwa ezifana ne-polyethylene (PE). Ikhonkco lokutya okukhawulezayo laseJapan libike ukuphucuka kwe-40% ekuchaseni i-grisi emva kokutshintshela kwiphepha elingangeni mafutha eliguqulwe yi-diatomite powder, ngelixa ligcina ukugquma kwephepha. Kwiphepha elishushu, elisetyenziselwa irisithi kunye neelebheli, i-diatomite powder isebenza njengomqhubi wobushushu, iphucula uvakalelo loshicilelo kwaye inciphise ukusetyenziswa kwamandla, ngaloo ndlela yandisa ubomi beentloko zoshicilelo olushushu.

Xa kusenziwa iphepha nge-diatomite powder, kufuneka kuqwalaselwe izinto ezininzi, kuquka ukuhambelana kwe-pH, ukusasazwa, kunye namanqanaba okulayisha. I-Diatomite powder ibonisa uzinzo ngaphakathi koluhlu lwe-pH olungathathi cala ukuya kolwe-alkaline kancinci (6.5-8.0) oluqhelekileyo kwiinkqubo zanamhlanje zokwenza iphepha, oluthintela ukuwohloka kwefayibha ebangelwa yi-asidi. Ukusasazwa ngokufanelekileyo, okufezekiswa ngokusebenzisa ii-hydropulpers okanye izisasazi, kubalulekile ukuthintela ukuhlangana kwamasuntswana, okunokukhokelela kwiziphene zephepha ezifana namabala okanye imingxunya. Amanqanaba okulayisha ayahluka ngokuxhomekeke kwisicelo: 5-10% yokuprinta nokubhala iphepha, 10-15% yephepha lokupakisha, kunye ne-15-20% yephepha elikhethekileyo. Ukudlula i-20% kunokuphazamisa ukuguquguquka kwephepha, nto leyo ebangela ukuba kufuneke ukulungiswa komxube wefayibha.

Ukuqukumbela, i-diatomite powder itshintshe kakhulu ishishini lokwenza iphepha, inikezela ngenkqubela phambili ebalulekileyo ekungacacini, amandla, ukuprintwa, kunye nokuzinza. Amandla ayo okunciphisa ukusetyenziswa kwe-pulp, ukunciphisa iindleko, kunye nokuphucula ukusebenza kwephepha kuyibeka njengezinto ezikhethwayo kwiifektri ezivelisa uluhlu olubanzi lweemveliso zephepha. Njengoko eli shishini liqhubeka nokubeka phambili ulawulo lokusingqongileyo kunye nokugqwesa kwemveliso, imfuno yehlabathi ye-diatomite powder yomgangatho wokwenza iphepha ikulungele ukukhula okukhulu. Le ndlela igxininisa indima ebalulekileyo yezixhobo ekubumbeni ikamva lokwenza iphepha elizinzileyo, ukuqhuba ubuchule, kunye nokuhlangabezana neemfuno eziguqukayo zabathengi kunye namashishini ngokufanayo. Ukuhlanganiswa kwe-diatomite powder kwiinkqubo zokwenza iphepha kubonisa inyathelo elibalulekileyo phambili ekufuneni imveliso yephepha esebenza kakuhle, enobuhlobo nokusingqongileyo, kunye nokusebenza okuphezulu.
