Thaum lub tshuab luam ntawv teb lub tshuab luam ntawv luam tawm, tom qab cov xim muab tshuaj nkag mus rau lub vijtsam teb los ntawm lub twj tso kua mis thiab cov yeeb nkab pub mis, cov xim muab tshuaj yog sib npaug ntawm qhov ntev ntawm lub vijtsam teb los ntawm cov khoom sib npaug, thiab txuas nrog lub scraper. ntawm ib sab. Nyob rau hauv qhov kev txiav txim ntawm lub ntiajteb txawj nqus thiab lub siab, cov xim paste seeps tawm ntawm lub mesh nyob rau hauv lub slurry cia cheeb tsam thiab yog luam tawm nyob rau hauv cov ntaub.
Feem ntau, cov nyhuv luam ntawv yog ntsuas los ntawm cov xim tsis sib xws, cov ntsiab lus txhais, xim siv, thiab lwm yam. Cov yam ntxwv no muaj feem xyuam rau qhov ntws ntawm cov xim muab tshuaj txhuam. Piv txwv li, xim uniformity yuav tsum tau kom tus nqi ntawm slurry yuav tsum tau khaws cia zoo ib yam ntawm txhua yam ntawm tib qauv units; Cov lus piav qhia yuav tsum muaj cov qauv meej thiab kab npoo, thiab tom qab cov xim muab tshuaj txhuam mus txog ntawm cov ntaub, yuav muaj kev tsiv teb tsaws tsawg thiab seepage; Xim siv yuav tsum tau txhua tus qauv Qhov xav tau ntawm cov xim yuav tsum tau txais ntawm txhua hom pixel. Yog li ntawd, txhawm rau ua tiav qhov zoo tshaj plaws luam ntawv zoo, yuav tsum muaj qhov tsim nyog ntawm cov tawv nqaij hauv txhua qhov luam ntawv ntawm cov ntaub. Yog li ntawd, nws tsim nyog kawm txog kev cuam tshuam ntawm cov duab geometric thiab lub cev ntawm txhua yam ntawm lub tshuab luam ntawv thiab qhov chaw muab tshuaj txhuam rau ntawm qhov ntws ntawm cov xim muab tshuaj txhuam thaum siv cov xim paste, thiaj li ua kom tsim nyog configurations raws li qhov kev thov. degree ntawm lawv lub hwj chim.
Rau cov nyhuv luam ntawv, qhov tseem ceeb tshaj plaws yog daim ntawv thov cov xim muab tshuaj txhuam. Qhov no tsuas yog txiav txim siab los ntawm cov txheej txheem squeegee siv. Cov luam ntawv paste ntws los ntawm cov yeeb nkab sizing mus rau sab hauv ntawm lub vijtsam teb, thiab tus kws kho mob cov hniav thiab cov rotating rotary screen tsim ib qho qhib luam ntawv paste retention wedge-shaped area. Nyob rau hauv thaj tsam ntawm lub tshuab luam ntawv muab tshuaj txhuam, vim yog kev sib hloov ntawm lub vijtsam rotary, ib txheej xim muab tshuaj txhuam ze rau ntawm lub vijtsam teb yog tsav los ua kom muaj kev sib tw khiav, uas ua rau muaj qhov nrawm nrawm thiab txiav kev ntxhov siab hauv cov xim muab tshuaj. , uas ua rau ib tug dav qauv ntawm cov luam ntawv muab tshuaj txhuam. poob. Ntawm qhov imprinting point, lub swirling ntws yog thaiv los ntawm scraper thiab dheev nres, cov xim muab tshuaj yog nyem, thiab lub siab ntawm cov scraper thiab lub peev xwm ntawm cov kua theem nyob rau hauv cov npoo-zoo li tus cheeb tsam ua rau lub siab ntawm cov xim muab tshuaj txhuam. nyob rau hauv cheeb tsam no. Ceev ceev, vim thixotropy ntawm cov xim, nws cov qib slaughter yog ntxiv txo. Nyob rau hauv qhov kev txiav txim ntawm cov ntsiab lus saum toj no, cov xim muab tshuaj yog luam tawm ntawm cov ntaub los ntawm cov mesh. Tom qab lub embossing taw tes, lub siab raug tshem tawm, cov xim muab tshuaj txhuam rau ntawm daim ntaub yog rov qab, thiab cov seepage yog txwv. Qhov kev tiv thaiv ntawm cov ntawv luam tawm kom nkag mus rau lub vijtsam teb thiab qhov kev tawm tsam ntawm cov ntawv luam tawm kom nkag mus rau hauv cov ntaub yog qhov sib txawv rau cov kev taw qhia ntawm cov khoom siab ntawm cov luam ntawv muab tshuaj nyob rau hauv cheeb tsam. Qhov siab tshaj plaws ntawm cov ntawv luam tawm uas tuaj yeem nkag mus rau lub vijtsam teb tuaj yeem suav los ntawm cov khoom siv siab thiab thim rov qab ntawm cov ntawv luam tawm.
Rau qhov sib nqus pas nrig scraper, txij li cov pas nrig sib nqus rotates nrog lub vijtsam teb, cov xim muab tshuaj txhuam rau hauv kev sib cuag nrog nws kuj tau tsav, uas ua rau ob xim paste ntws nyob rau hauv cov npoo-zoo li qhov chaw ntawm cov muab tshuaj txhuam, thiab lawv raug txiav tawm ntawm lub imprinting point tib lub sij hawm. . Tsis tas li ntawd, nyob rau hauv kev sib hloov kev taw qhia ntawm lub vijtsam teb, pib los ntawm taw tes M, qhov kev ncua deb ntawm qhov chaw ntawm cov hlau nplaum sab nraud thiab sab hauv ntawm lub vijtsam rotary shrinks sai dua li qhov kev ncua deb ntawm qhov qis ntawm lub scraper thiab cov khoom siv. sab hauv ntawm lub vijtsam teb, yog li cov xim muab tshuaj txhuam Nws yog nruj dua, yog li qhov siab tshaj plaws ntawm qhov sib nqus bar ua ntej lub embossing point yog siab dua li ntawm cov scraper, yog li thaum lub magnetic bar luam tawm, cov xim paste yog pauv. rau sab nraub qaum ntawm cov ntaub pom tseeb, qhov kev pab cuam zoo, thiab cov khoom siv pulp tsawg dua. Higher paste pressures kuj ua rau muaj feem cuam tshuam ntawm kev hloov mus rau sab nraud ntawm paste, uas ua rau poob ntawm contour txhais.
