Ibhodi likathayela lingenye yezinto ezibalulekile ekukhiqizeni ibhodi likathayela. Ukungacaba kahle kwephepha lebhodi likathayela kuzoholela ezinhlobonhlobo zamakhothamo ebhodi likathayela, ukubhajwa kalula ngesikhathi sokuphrinta kwe-adsorption ngomshini futhi kubangele ukuba ibhodi lephepha lichithwe futhi liphoqwe ukuthi livalwe ukuze lihlanzwe; i-inki engalingani, ukufanisa imibala okungalungile, kanye nezikhala zonqenqema olugqagqene zingenzeka kalula ekuphrinteni ngemibala emibili noma ekuphrinteni ngemibala eminingi; ukugudluzwa kosayizi we-groove engaphezulu nephansi emshinini wokuphrinta kuzodala ukunqwabelana noma okungewona umthungo wekhava elingaphezulu nangaphansi lebhokisi; ukusika nokufa kuzokhiqizwa futhi Ukukhubazeka okufana nokunamathela kanye nokugudluzwa kosayizi kungase kuholele ekumoshweni kwesibili kwebhodi lephepha elihle, noma ukulimala kwemishini, futhi kuphoqeleke ukuthi kumiswe ukuqeda. Ngamafuphi nje, ukunganaki kahle kwebhodi lephepha kuzokwenza ukuthi ukudla kungabi lula futhi kuholele ekwenyukeni kwemikhiqizo kadoti yesibili ohlelweni lokukhiqiza.
Ukuze kuthuthukiswe ukucaba kwesigaba sezinto zikathayela, siqinisekise izinga elifanelekile lekhwalithi yomkhiqizo nokusebenza kahle kokukhiqiza okuvamile, besihlola futhi sihlaziya njalo umkhuba wokukhiqiza amabhokisi, futhi sathola izindlela zokuthuthukisa. Ifingqiwe kanje ukuze kubhekiselwe kuyo kuphela.
Ukubonakala kwebhodi likathayela eline-flatness elimpofu lingahlukaniswa ngezinhlobo ezintathu: i-arch transverse, i-arch longitudinal kanye ne-arch engaqondakali.
I-Arch Transverse ibhekisela ku-arch eyakhiwe eduze kwesiqondiso sikathayela. I-Longitudinal arch ibhekisela ku-arch ekhiqizwa ibhodi lephepha elihambisana nesivinini somugqa wokukhiqiza. I-arch engafanele iyikhothamo eliguquguqukayo kunoma iyiphi indlela. I-arch ebusweni bephepha ibizwa ngokuthi i-arch eqondile, ukuthi phezu kwephepha elingaphakathi libizwa ngokuthi i-arch e-negative, nokuthi ebusweni bephepha elingaphakathi linokwehla nokwenyuka kubizwa ngokuthi i-arch positive nenegetive.
Izici eziyinhloko ezithinta ukucaba kwebhodi lephepha
1. Kunezinhlobo ezahlukene namabanga ephepha ngaphakathi. Kukhona iphepha le-kraft elivela kwamanye amazwe nelifuywayo, iphepha lokulingisa le-kraft, iphepha likathayela, iphepha lebhodi letiye, iphepha eliqinile eliqinile, njalonjalo, futhi lihlukaniswe ngo-a, B, C, D, e, grade. Ngokomehluko wezinto zephepha, iphepha elingaphezulu lingcono kunephepha langaphakathi.
