Adhesive cov ntaub ntawv tearing thaum pov tseg? Cov laj thawj no yuav tsum tsis txhob ignored!
Nws yog ib qho tseem ceeb rau qhov khib nyiab ntawm tus kheej -cov ntaub ntawv nplaum kom tawg thaum tuag- txiav. Thaum tawg tshwm sim, cov neeg ua haujlwm yuav tsum tau tso tseg lub tshuab kom rov txhim kho cov ntug dej khib nyiab, uas ua rau txo qis kev tsim khoom thiab nce cov khoom siv raw khoom pov tseg. Yog li, dab tsi yog qhov ua rau pov tseg - ntug kev tawg hauv tus kheej - cov khoom nplaum tuag- txiav, thiab yuav ua li cas nrog nws?
01 Tsawg tensile lub zog ntawm cov khoom nws tus kheej ua rau pov tseg - ntug tawg
Qee cov ntaub ntawv, xws li cov ntawv coated (tseem hu ua glossy coated paper), muaj cov ntawv luv luv thiab tsis yooj yim. Thaum lub sij hawm tuag-txiav cov txheej txheem tshem tawm, lub zog tensile ntawm ntug khib nyiab yog qis dua qhov nro ntawm cov khoom siv, ua rau nws yooj yim tawg.
Nyob rau hauv cov ntaub ntawv no, nws yog ib qhov tsim nyog los txo cov khoom siv pov tseg qhov nro kom ntau li ntau tau. Yog tias cov cuab yeej tshem tawm qhov nro twb tau teeb tsa rau theem qis tshaj plaws tab sis qhov teeb meem tshwm sim, tom qab ntawd thaum lub sij hawm tsim cov txheej txheem ua ntej, cov ntug khib nyiab yuav tsum tau tsim dav dua kom ntseeg tau tias cov khib nyiab - ntug tawg tsis tshwm sim ntau zaus thaum tuag- txiav.
02 Cov txheej txheem tsis tsim nyog tsim / dhau qhov nqaim pov tseg ntug ua rau tawg
Ntau daim ntawv lo siv rau cov ntaub ntawv sib txawv ntawm kev luam ntawv ntawm kev lag luam tuaj nrog yooj yim - kua muag dotted kab txiav. Qee tus kheej -cov tuam txhab ua cov ntawv nplaum, vim muaj kev txwv cov khoom siv, yuav tsum tso cov dotted txiav thiab ciam teb txiav rau tib qhov tuag- chaw txiav. Tsis tas li ntawd, vim yog cov nqi thiab cov nqi, cov ntug khib nyiab yog tsim los nqaim heev, feem ntau tsuas yog 1 hli dav. Qhov no tuag-txiav txheej txheem xav tau ntau los ntawm cov khoom siv daim ntawv lo, thiab qhov yuam kev me me tuaj yeem ua rau khib nyiab yooj yim-ntug tawg, yog li cuam tshuam rau kev tsim khoom.
Nws tau pom zoo tias tus kheej -cov tuam txhab ua cov nplaum nplaum, thaum twg cov xwm txheej tso cai, cais qhov yooj yim - kua muag dotted kab txiav los ntawm daim ntawv ciam teb thaum tuag- txiav. Qhov no tsis yog tsuas yog txo qhov zaus ntawm cov khib nyiab-ntug breakage tab sis kuj tseem tuaj yeem ua rau kom tuag ntau dua - txiav ceev. Cov tuam txhab uas tsis muaj tus mob no tuaj yeem daws qhov teeb meem los ntawm kev kho qhov feem ntawm cov dotted txiav los yog tshem tawm ib feem ntawm cov dotted txiav uas txuas dhau ntawm daim ntawv lo ciam teb.
03 Cov khoom tsis xws luag ua rau pov tseg - ntug tawg
Kev tawg ntawm tus kheej - cov khoom nplaum kuj tuaj yeem ua rau khib nyiab yooj yim - ntug tawg. Qhov teeb meem no yooj yim los txheeb xyuas thiab yuav tsis piav qhia ntawm no. Nws yuav tsum raug sau tseg tias qee qhov ntawm tus kheej - cov ntaub nplaum nplaum muaj cov npoo me me uas tsis yooj yim pom thiab yuav tsum tau ua tib zoo saib xyuas. Rau cov xwm txheej zoo li no, cov khoom siv tsis raug yuav tsum tau muab tshem tawm ua ntej tuag- txiav.
04 Ntau cov nplaum ntws los yog dhau - daim ntawv thov ua rau khib nyiab - ntug tawg
Tus nqi ntawm cov nplaum siv rau hauv tus kheej- cov ntaub ntawv nplaum cuam tshuam rau lawv qhov tuag- txiav kev ua haujlwm. Feem ntau, ntawm kev tuag- cov cuab yeej txiav, tus kheej- cov khoom nplaum tsis raug tshem tawm tam sim tom qab tuag- txiav tab sis raug thauj mus rau ib qho kev ncua deb, thiab tsuas yog tom qab ntawd tshem tawm cov pov tseg. Yog tias cov nplaum siv ntau dhau, thaum thauj los ntawm qhov tuag- txiav qhov chaw nres tsheb mus rau qhov chaw tshem tawm cov khib nyiab, cov nplaum yuav ntws rov qab, ua rau cov khoom uas twb tau txiav lawm - nplaum ntsej muag los lo ua ke, uas ua rau cov khib nyiab tawg thaum rub tawm vim adhesion.
Feem ntau, tus nqi txheej rau dej-raws li acrylic nplaum yuav tsum nyob nruab nrab ntawm 18 thiab 22 grams ib square meter, thaum kub yaj nplaum nplaum yuav tsum nyob nruab nrab ntawm 15 thiab 18 grams ib square meter. Tshaj qhov ntau yam no ua rau muaj feem ntau ntawm cov khib nyiab- ntug tawg. Qee cov nplaum, txawm tias tsis siv rau ntau qhov ntau, tseem tuaj yeem ua rau khib nyiab vim lawv cov dej ntws siab.
Thaum ntsib cov teeb meem zoo li no, koj tuaj yeem saib thawj zaug seb puas muaj qhov tshwm sim loj heev ntawm cov ntug khib nyiab thiab daim ntawv lo. Yog tias txoj hlua khi hnyav heev, nws qhia tau tias cov nplaum nplaum loj los yog nws cov fluidity muaj zog. Qhov teeb meem no tuaj yeem daws tau los ntawm kev siv qee cov roj silicone ntxiv rau qhov tuag lossis los ntawm cua sov nrog cov hluav taws xob cua sov. Silicone roj additive tuaj yeem ua rau qeeb rov qab ntawm cov nplaum, thaum cua sov rau tus kheej - cov khoom nplaum tuaj yeem ua kom cov nplaum sai sai, yog li txo qhov kev sib tw ntawm txoj hlua.
05 Tuag cuab tam tsis xws luag ua rau pov tseg ntug breakage
Cov cuab yeej tuag tsis zoo kuj tuaj yeem ua rau khib nyiab tawg yooj yim. Piv txwv li, me me me me ntawm ntug hniav tuaj yeem tiv thaiv cov khoom siv lub ntsej muag los ntawm kev txiav tag nrho. Qhov tsis raug txiav feem ntau muaj zog ntau dua piv rau lwm qhov, ua rau nws yooj yim dua rau kev tawg. Qhov tshwm sim no kuj yooj yim rau kev txiav txim siab vim tias qhov chaw ntawm qhov tawg yog tsau. Nyob rau hauv tas li ntawd, cov tuag puas yuav tsum xub kho ua ntej yuav siv rau tuag- txiav.
