Kwiminyaka yakutshanje, abavelisi bephepha kunye nabasebenzisi baye bahlawula ingqalelo ngakumbi nangakumbi kumthamo wephepha, kuba umthamo unempembelelo enkulu kwiindleko kunye nokusebenza kwemveliso.Ubuninzi bobuninzi obuphezulu buthetha ukuba ubukhulu obufanayo, ubunzima besiseko bunokuncitshiswa kwaye inani lefiber esetyenzisiweyo lingancitshiswa, ukuze kuphunyezwe injongo yokonga iindleko;umthamo omkhulu unokunyusa ukuqina kwephepha, ukuvumela abapapashi beencwadi ukuba bagcine iincwadi ezipheleleyo ezinamaphepha ambalwa Ukutyeba kunokunyusa ukucaca kwephepha, ukuprinta kunye nokunciphisa ukuvuza kwe-inki yokushicilela.Ngoko ke, i-Takamatsu ibaluleke kakhulu kulawulo lweendleko zephepha, ukusebenza kwemveliso kunye nexabiso elongezelelweyo kwimveliso.
Yintoni ivolumu ephezulu?Esi sisalathiso esibalulekileyo sephepha, oko kukuthi, umlinganiselo wesiseko sobunzima bobunzima.Umthamo ubonisa ubuninzi bephepha, oko kukuthi, ubukhulu be-porosity yephepha.
Izinto eziphambili ezichaphazela umthamo wephepha ziquka i-fiber fiber ekrwada, uhlobo lwe-pulp, ukubetha ukusebenza, ukugcwaliswa, iikhemikhali, ukucinezela, ukomisa, i-calendering, njl.
I-fiber morphology ye-papermaking fiber ekrwada inempembelelo ebalulekileyo kubuninzi bephepha.Iintsinga ezityebileyo zine-porosity ephezulu kunye noxinano olukhulu lwephepha, kodwa ukuxinana kwesambuku akuhambisani kuphela nobukhulu befayibha, kodwa bukwanobudlelwane obubaluleke kakhulu kunye nokuqhekeka kwefayibha kwinkqubo yokwenza iphepha.Ekugqibeleni kuxhomekeke ekubeni zingakanani iintsinga ezaphukileyo kunye nokukhubazeka.Ke ngoko, iintsinga ezinobubanzi obuncinci kunye nodonga olungqingqwa ziqinile, azityumki lula, kwaye zenza iphepha elinoxinaniso oluphezulu.
Uhlobo lwe-pulp lunempembelelo enkulu kumthamo wephepha.Xa sithetha nje jikelele, isivuno esikhulu sentlama > i-pulp ye-thermomechanical > kraft pulp > inkunkuma yenkunkuma.Iimathiriyeli ekrwada ezahlukeneyo zinevolumu eyahlukileyo kwipulp enye, i-hardwood> softwood.Ubuninzi obuphezulu be-pulp ye-high-ield ayifani nezinye iipulp, ngoko ke i-pulp ye-high-ield isetyenziswa ngokubanzi ukufaka indawo ye-bleached kraft hardwood pulp kwiphepha eliphezulu.Ukukhethwa kunye nomlinganiselo weentlobo ze-pulp zingundoqo kwiteknoloji yokuvelisa iphepha eliphezulu langoku.Ukongeza i-pulp yemveliso ephezulu ukuphucula ukuxinana kwephepha ngoku kuyeyona ndlela isebenzayo esetyenziswa ngokubanzi ngabasila bephepha.
Umthamo luphawu olubaluleke kakhulu lwephepha.Iphepha eliphezulu lokuxinana kwesambuku linokugcina ukuqina okuyimfuneko, ukunciphisa ukusetyenziswa kwefayibha, konga iindleko zepulp kunye nokuphucula ukuxinana kwesambuku.Ezona ndlela zisebenzayo okwangoku zibandakanya ukongezwa kwe-pulp yesivuno esiphezulu, ukhetho lwe-pulp kunye neenkqubo zenkqubo.Ukulungiswa kunye nophuhliso lwezongezo ezitsha ezininzi lukwayindlela ebalulekileyo yophando.
