Okokuqala, kufuneka ukwazi iimpawu zephepha eligqunyiweyo, kwaye emva koko unokwazi ngakumbi izakhono zayo.
Iimpawu zephepha eligqunywe:
Iimpawu zephepha eligqunyiweyo kukuba umphezulu wephepha ugudileyo kakhulu kwaye ugudileyo, kunye nokuguda okuphezulu kunye neglosi elungileyo.Ngenxa yokuba ubumhlophe bengubo esetyenzisiweyo bungaphezulu kwe-90%, kwaye amaqhekeza ahle kakhulu, kwaye i-calendered yi-calender ephezulu, ukugudiswa kwephepha elifihliweyo ngokuqhelekileyo li-600-1000s.Ngelo xesha, ipeyinti ihanjiswa ngokulinganayo kwiphepha kwaye ibonakala ikholisa umhlophe.Iimfuno zephepha elifihliweyo kukuba iingubo zincinci kwaye zifanayo, ngaphandle kwamaqamza, kwaye ubungakanani be-adhesive kwi-coating ifanelekile ukukhusela iphepha kwi-de-powdering kunye ne-fluffing ngexesha lenkqubo yokushicilela.Ukongeza, iphepha eligqunyiweyo kufuneka libe nokufunxa okufanelekileyo kwexylene.Ibhokisi yokutya
Ukusetyenziswa kwephepha eligqunyiweyo:
Iphepha eligqunyiweyo lelinye lawona maphepha aphambili asetyenziswa kwimizi-mveliso yokushicilela.Iphepha eligqunyiweyo liqhele ukubizwa ngokuba liphepha elityathiweyo lokuprinta.Isetyenziswa ngokubanzi kubomi benene.Umzekelo, iibhokisi zokupakisha ukutya, iikhalenda ezintle, amaqweqwe eencwadi, imizobo, iialbham zemifanekiso, imveliso yoshicilelo lwesixhobo sombane kwimizi-mveliso, phantse zonke zisebenzisa amaphepha agqunyiweyo, ukupakishwa okuhonjiswe kakuhle, iibhegi zephepha, iilebhile, iimpawu zorhwebo, njl. njl. ikwasetyenziswa ngobuninzi.Iphepha elisetyenziswa ngokuqhelekileyo lahlulahlulwe ngokwemilinganiselo yobukhulu obahlukeneyo ukusuka kwi-70 grams nge square metre ukuya kwi-350 grams nge-square meter nganye.

Ukuhlelwa kwephepha eligqunyiweyo:
Iphepha eligqunyiweyo linokohlulwa libe licala elinye eliqatywe ngecala elinye, iphepha elicandisiweyo elinamacala amabini, iphepha eliqatywe ngemathi nelaphu eliqatywe ngelaphu.Ngokomgangatho wahlulwe waba ngamabakala A, B, C amathathu.Izixhobo eziphambili zephepha eligqunyiweyo liphepha elisezantsi kunye nepeyinti.Iimfuno zephepha elisisiseko eligqunyiweyo lilingana nobukhulu obufanayo, ukuguquguquka okuncinci, amandla aphezulu kunye nokuchasana kwamanzi okulungileyo.Akufanele kubekho amabala, imibimbi, imingxuma kunye nezinye iziphene zamaphepha kumphezulu wephepha.Ingubo esetyenziselwa ukugquma iqulethwe ngamabala amhlophe aphezulu (afana ne-kaolin, i-barium sulfate, njl.), i-adhesives (njenge-polyvinyl alcohol, i-casein, njl.) kunye nezongezo ezincedisayo.ye.

Ubume bephepha eliqatywe:
Iphepha eligqunyiweyo linephepha elisicaba kunye nephepha lokuqengqeleka.Iphepha elisisiseko elicatyiswe lenziwe ngentlama yomthi wekhemikhali efakwe iblitshi okanye intlama yengca yekhemikhali efakwe iblitshi kumatshini wephepha.Ngephepha lesiseko njengesiseko sephepha, ii-pigments ezimhlophe (ezaziwa ngokuba ngudongwe, ezifana ne-kaolin, i-talc, i-calcium carbonate, i-titanium dioxide, njl. ezinye izinto ezincedisayo (ezifana neglosi, iihardeners, plasticizers, dispersants, wetting agents, opalescent agents, optical brighteners, toners, etc.), iyunifomu igqunywe kumatshini wokugquma, kwaye omisiweyo kunye ne-super calendered eyenziwe.Umgangatho wephepha ufana kwaye uqinile, ubumhlophe buphezulu (ngaphezu kwe-85%), ubuso bephepha bubushelelezi kwaye bucwebezelayo, kwaye i-coating iqinile kwaye ihambelana.Ibhokisi yekeyiki
