Sib tham txog tus lej ntawm tus lej thiab nws txoj kev sib raug zoo nrog kev luam ntawv zoo
Peb yog ib lub tuam txhab luam ntawv loj hauv Shenzhen Tuam Tshoj. Peb muaj cov phau ntawv luam tawm, phau ntawv xov xwm luam ntawv, phau ntawv luam ntawv, phau ntawv nyuaj, phau ntawv luam tawm, phau ntawv luam tawm, phau ntawv luam tawm, lub thawv ntim, daim qhia ntawv, txhua yam ntawm PVC, cov ntawv luam tawm, ntawv sau cia, hom tshwj xeeb ntawv xim luam tawm khoom, kev ua si cardand li ntawd.

Cov lej luam ntawv yog ib qho khoom ua ke zoo li cov khoom sib xyaw uas muaj xim, ib phau ntawv, ib cov tub luam thiab cov zoo li. Raws li ib hom kua xiav kua xau, qhov ua tau zoo ntawm cov ntau yam kuj tsis zoo, uas yog, cov ntsiab lus tuab thiab thin, qhov sib txawv ntawm qhov sib txawv, ceev kom qhuav thiab qeeb qis. Yog li ntawd, kom to taub thiab to taub lub luag hauj lwm ntawm cov cwj mem ntawm tus cwj pwm hauv tus cwj pwm yog qhov tseem ceeb ntawm kev kho kom yog ntawm tus cwj pwm ntawm tus cwj pwm, txaus siab rau kev tsim tau ntau yam luam ntawv, thiab kev txhim kho cov luam ntawv zoo ntawm qhov khoom.
Ua ntej, lub luag haujlwm ntawm colorants nyob rau hauv tus number case
Pigments muaj pigments thiab dyes. Cov ntaub ntawv xim siv hauv cov ntawv phom sij yog feem ntau cov pigments, thiab ib co dyes tseem siv, uas yog txhua yam zoo xim cov ntaub ntawv. Pigments feem ntau tsis muaj dej nyob hauv thiab tsis yaj rau hauv phau ntawv, thiab feem ntau ntawm cov tshuaj yog nyob rau hauv kev ncua, thiab lub zas yog feem ntau soluble nyob rau hauv lub binder. Pigments muaj cov cwj pwm zoo rau kev ua tau zoo ntawm tus cwj mem. Qhov ntom ntom nti, qhov kaj, qhov kub ntawm lub zog, lub teeb pom kev thiab tsis pom zoo rau cov tshuaj ntawm tus cwj pwm yog txhua yam muaj feem xyuam xim. Lub luag haujlwm ntawm cov pigment hauv tus number case yog pom tseeb. Nws cov xim txiav txim siab txog tus hawj ntawm tus number case; nws cov nyiaj txiav txim siab qhov concentration ntawm tus number case; nws siv tau tus number case ib lub ntsiab lus thiab lwm yam khoom siv lub cev; nws siv kev cuam tshuam rau ib qho twg Luv nquag drying, oxidative polymerization thiab ziab khaub ncaws raws li cov phom yog tshwj xeeb heev. Tsis tas li ntawd, cov xim ntawm tus cwj mem nyob hauv txhua txoj haujlwm kuj yog txiav txim los ntawm cov xim. Yog li ntawd, vim muaj ntau yam phaw thiab siv, kev siv cov pigments kuj sib txawv. Qhov no yuav tsum tau hais tias cov phev yuav tsum raug xaiv raws li cov khoom siv thiab cov txheej txheem tus yam ntxwv thaum luam tawm. Piv txwv, cov xim siv luam yeeb siab ntau zaus yuav tsum siv los luam cov khoom. Yoojyim, looj hauv lub cev kom tiv thaiv kom zoo.
Qhov ob, lub luag hauj lwm ntawm tus binder nyob rau hauv tus number case
Cov phom yog kua uas muaj viscosity thiab viscosity, thiab nws txoj haujlwm yog ntau-faceted. Raws li tus cab kuj ntawm cov pigment, khoom seem powdery pigment yog tov thiab koom ua ke, thiab cov xim uas adheres rau naam yog thaum kawg ua adhered rau cov ntawv luam tawm. Cov kab lus cuam tshuam thiab txiav txim siab kho qhov ceev, qhov ziab kom qhuav thiab ziab ziab khaub ncaws, thiab muab tus cwj mem los ntawm tej yam khoom hauv lub cev xws li ci ntsa iab, kev sib zog ua hauj lwm, kev tiv thaiv daj thiab kev ua hauj lwm, thiab loj npaum licas Lub viscosity, viscosity, yield tus nqi thiab tus nplua nuj ntawm tus cwj pwm yog txiav txim siab, yog li zoo siab cov phev yog muab los ntawm cov khi khiab loj. Yog hais tias qhov kev npaj ntawm tus binder los yog txoj kev ua tsis zoo tsim nyog, tus cwj mem tsis tsuas yog tsis muaj xim, siab zoo nkauj, tab sis kuj ua rau cov khoom poob tsis zoo xws li muab tshuaj txhuam, pleev xim rau, tshem ntawv, thiab tsis muaj kua. Coj ib txhia teeb meem. Yog li, tus binder yog ib qho zoo tshaj uas cuam tshuam rau qhov zoo tshaj ntawm tus number case.
Qhov peb, lub luag hauj lwm ntawm qhov muab tub lim rau ntawm tus cwj mem
Lub muab tub lim yog cov khoom dawb uas tuaj yeem ua tau zoo thiab zoo dispersed hauv lub binder, thiab yog hmoov zoo. Thaum cov neeg muab tub lim hnav yog slurried tom qab tov thiab hauv pem teb hauv lub binder, ib txhia yog pob tshab thiab qee qhov yog opaque. Feem ntau siv cov ntaub fillers yog txhuas hydroxide, potassium sulfate, magnesium carbonate, thiab calcium carbonate. Hauv cov ciaj ciam, cov ntaub so ntswg tuaj yeem kho tus cwj pwm sib xyaw mis, viscosity, viscosity, fluidity thiab yield yield ntawm ib sab tes, thiab kho tus number case concentration ntawm lwm tes, uas yog, thaum number case concentration loj, tus hue sib sib zog nqus. Nyob rau hauv rooj plaub, tom qab ntxiv qhov muab tub lim, txoj kev siv cov nyhuv yuav ua tiav. Txawm hais tias tus neeg muab kev pabcuam muaj kev pabcuam hauv tus cwjpwm, nws qhov kev ua haujlwm muaj ntau yam uas yuav tsum ua raws li cov pigment, thiab nws tseem cuam tshuam tus txhauv hauv tus cwjpwm uas yog tsim los ntawm oxidative polymerization kom qhuav.
Plaub, lub luag haujlwm ntawm cov khoom siv ntxiv hauv tus cwj mem
Rau tus neeg teb xov tooj luam ntawv, cov ntawv luam tawm ntawm tus cwj pwm zoo yog qhov zoo, thiab qhov qhib hluav taws muaj peev xwm muab tso rau hauv kev siv, uas yog ntawm chav kawm qhov yooj yim tshaj plaws thiab yooj yim. Txawm li cas los xij, vim qhov txawv ntawm qhov kub thiab txias ntawm lub chaw luam ntawv, cov yam ntxwv ntawm cov khoom siv luam tawm thiab cov txheej txheem luam ntawv, xws li cov dej ntsiab lus ntawm daim ntawv, pH nqi ntawm lub tshuab luam ntawv, kev ceev ntawm lub tshuab luam ntawv , hom ntawv luam tawm, thiab lwm yam, txawm hais tias tus cwj mem ntau hom muaj ntau, txhua qhov piv txwv ntawm cov pigments, cov khoom ntim, thiab cov pob uas siv cov phev yog yuav luag tas li, thiab feem ntau tsis tuaj yeem ua raws li cov kev xav tau ntawm ntau yam kev mob. Yog li ntawd, los ntawm qhov pom ntawm kev txhim kho ergonomics thiab zoo ntawm luam ntawv, nws yog ib qho zoo kom muaj kev luam ntawv kom zoo raws li cov ntau yam luam ntawv uas cov additives muaj paab ntxiv rau qhov xaiv xaj.
