Cov khoom nplaum puas tawg thaum lub sij hawm 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 cov khib nyiab 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 breakage
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 qhov nro ntawm cov khoom siv pov tseg. Yog tias qhov nro twb tau teem rau qhov tsawg kawg nkaus thiab qhov teeb meem tshwm sim, tom qab ntawd nyob rau theem pib ntawm cov txheej txheem tsim, cov ntug khib nyiab yuav tsum tau tsim kom dav dua kom ntseeg tau tias tsis tu ncua ntawm cov ntug khib nyiab tsis tshwm sim 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 hauv kev ua lag luam tam sim no muaj cov kab sib tw ua tau zoo. Qee tus kheej -cov tuam txhab ua cov ntawv nplaum nplaum, txwv los ntawm lawv cov khoom siv, yuav tsum tso cov qhab nia thiab txiav ciam teb rau tib qhov tuag- chaw txiav. Tsis tas li ntawd, xav txog cov nqi thiab cov nqi, cov ntug khib nyiab feem ntau tsim nqaim heev, feem ntau tsuas yog 1 hli dav. Qhov no tuag- txheej txheem txiav yuav tsum muaj cov khoom zoo heev, thiab txawm tias muaj teeb meem me me tuaj yeem ua rau muaj kev puas tsuaj ntawm ntug kev, cuam tshuam rau kev tsim khoom.
Tus kws sau ntawv qhia tias, thaum twg los tau, tus kheej -cov tuam txhab ua cov nplaum nplaum yuav tsum tuag- txiav cov qhab nia sib cais ntawm daim ntawv lo ciam teb. Qhov no tsis yog tsuas yog txo qhov zaus ntawm cov khib nyiab tawg tab sis kuj tseem ua rau kom tuag- txiav ceev. Rau cov tuam txhab uas tsis muaj cov xwm txheej ua li ntawd, lawv tuaj yeem daws qhov teeb meem los ntawm kev kho qhov ntsuas ntawm cov qhab nia kab lossis tshem tawm cov feem ntawm cov qhab nia kab uas txuas ntxiv dhau ntawm daim ntawv cim ciam teb.
03 Raw khoom tsis xws luag ua rau khib nyiab ntug breakage
Cov khoom tsis zoo hauv cov khoom siv raw tuaj yeem yooj yim ua rau pov tseg ntug tawg. Qhov teeb meem no yooj yim los txheeb xyuas, yog li nws yuav tsis piav qhia ntawm no. Nws yuav tsum raug sau tseg tias qee qhov ntawm tus kheej - cov ntaub nplaum nplaum muaj qhov cuam tshuam me me uas tsis yooj yim pom thiab yuav tsum tau ua tib zoo saib xyuas kom pom. Thaum ntsib teeb meem zoo li no, tsuas yog tshem tawm cov khoom tsis zoo ua ntej yuav tuag- txiav.
04 Cov nplaum nplaum ntau dhau los yog cov txheej txheem ntau dhau ua rau cov ntug kev tawg
Tus nqi ntawm cov nplaum txheej ntawm tus kheej- cov ntaub ntawv nplaum muaj qhov cuam tshuam loj rau lawv qhov tuag- txiav kev ua haujlwm. Feem ntau, hauv kev tuag- cov cuab yeej txiav, tus kheej- cov khoom nplaum tsis tau muab pov tseg tam sim tom qab txiav tab sis txuas ntxiv mus rau tom ntej luv luv ua ntej mus txog qhov chaw tshem tawm pov tseg. Yog tias cov nplaum yog coated heev, thaum lub sij hawm hloov los ntawm qhov tuag- txiav qhov chaw nres tsheb mus rau qhov chaw tshem tawm cov khib nyiab, cov nplaum tuaj yeem ntws rov qab, ua rau cov khoom txiav uas twb tau txiav los ua ke dua, ua rau tawg ntawm ntug khib nyiab thaum rub tawm.
Feem ntau, cov txheej txheem rau dej-raws li acrylic nplaum yuav tsum nyob nruab nrab ntawm 18-22 grams ib square meter, thaum kub- cov nplaum nplaum yuav tsum nyob nruab nrab ntawm 15-18 grams ib square meter. Tshaj qhov ntau yam no ua rau muaj feem cuam tshuam ntawm cov ntug dej khib nyiab. Qee cov nplaum, txawm tias siv me me, tuaj yeem ua rau khib nyiab vim lawv cov fluidity 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. Hauv cov xwm txheej zoo li no, cov tuag puas yuav tsum tau kho ua ntej siv rau kev tuag- txiav.
