Nyob rau hauv qhov tseeb, lawv yog ib tug khub ntawm faults nyob rau hauv daim ntawv rov qab - lub paj phaj thiab daim txiag phom. Hom kev txhaum no yog qhov tseem ceeb tshaj plaws nyob rau hauv lithography. Qhov tshwm sim.
I. Paj Tsab
Thaum luam tawm ntawm lub qhov hluav taws xob, lub phaj luam tawm yog txo. Lub emptiness disappears, nws yog hu ua lub paj version. Cov kab me me ntawm cov ntawv phaj. Cov ntawv nyeem ploj, tseem hu ua lub paj version. Thaum lub paj version tshwm sim, lub siab-profile nplua mesh yuav sai sai no yuav ploj mus. Nyob rau hauv lub tshav pob Hauv cov ntawv luam tawm, qhov tshwm sim ntawm cov nplua vim qhov kev puas tsuaj ntawm lub hauv paus roj hauv paus raws li tseem hu ua lub paj version.
Lub ntsiab yog vim li cas rau lub paj phaj yog qhov chaw txhim kho thiab txhuam.
1. Tus thawj yog hais txog qhov nyiaj ntawm dampening daws thiab acidity ntawm dampening daws. Tus nqi ntawm dampening kua yog loj, uas ua rau emulsifying hnyav nce, uas yuav txo qhov dot loj, nplua mesh taw poob lawm, thiab lub paj phaj yog ua. Txoj kev dampening yog acidic thiab yuav tsim cov txiaj ntsig zoo li ntawd.
2. Kev sib txhuam ntawm daim ntawv luam tawm yog muab los ntawm kev sib cuag ntawm cov dej rau cov menyuam, cov quav rau tus kheej thiab cov pam. Cov kev sib txhuam nyob ntawm qhov sib luag ntawm lawv. Lub siab thiab qhov chaw mob. Cov kev sib txhuam ntawm cov phom luam yog kev txiav txim siab los ntawm kev sib txhuam. Dej rau cov menyuam, raws li daim pam thiab lub phaj ntawv, muaj kev sib txhuam los. Yog hais tias daim ntawv tsis muaj hmoov thaum lub sij hawm luam ntawv, txoj kev sib txhuam yuav ua rau mob ntxiv.
2. Muab tshuaj
Cov yam ntxwv ntawm cov phom muab tshuaj yog: qhov tsim teeb meem nthuav dav thiab deform, thiab lawv sib koom ua ke, ua lub txheej ntawm cov duab tsis meej xwm txheej. Nws yog feem ntau thaws rov los ntawm qhov qis-tseem ceeb ntawm daim duab.
Muaj ntau ntau yam rau cov khoom muab tshuaj, ntau yam yog nyob hauv dej, kua mem sau thiab siab.
1. Kev tswj cov dej npuaj kab yog ze rau qhov muab tshuaj txhuam. Cov dej yog me me, tus number case yog yooj yim rau kev nthuav dav, thiab cov teev kis, uas yuav ua rau muab tshuaj. Tus nqi tsawg tsawg, ntau tus zauv rau hauv tus qauv emulsification, thiab cov tshuaj muab los kuj tau. Emulsified number case yog pluag hauv roj, thiaj li hais tias nws floats dawb rau cov kua ciav dej. Nws xub nthuav tawm sab nraud ntawm qhov taw tes qes dua kom tsim tau ib qho muab tshuaj txhuam.
2. Ntau tus cwj mem yog ib qho ntawm cov hauv paus ntsis rau qhov muab tshuaj. Vim tias tus lej ntawm tus lej yuav ua rau kom lub dot kom nthuav, dhau sij hawm, nws yuav tsim ib qho muab tshuaj. Tin nyias kuj yog qhov ua rau ntawm qhov hnyav ntawm qhov muab tshuaj txhuam. Cov lej nyias nyias Kev loj heev, tom qab extrusion, nws ua ib qho kev tshwm sim muab tshuaj.
