Cov khoom siv lub cev thiab tshuaj ntawm tus cwj mem tsuas yog hais txog nws qhov ntom, zoo nkauj, pob tshab, lub ntsej muag, lub teeb tsis kam, tiv tshav kub, thiab kua qaub, alkali, dej, thiab hnyav (cawv) tsis kam.
Qhov ceev
Qhov ceev yog hais txog qhov hnyav ntawm tus number case rau ib chav ntim ntawm 20 ° C. Qhia nyob rau hauv g / cm3. Qhov ceev ntawm tus number case yog txiav txim siab los ntawm hom thiab qhov sib piv ntawm cov ntaub ntawv raw siv nyob rau hauv tus number case, thiab cuam tshuam los ntawm qhov kub sab nraud. Qhov ntom ntawm tus number case muaj qee yam kev sib raug zoo nrog cov txheej txheem luam ntawv. Qhov ntom ntawm number case muaj feem xyuam nrog tus nqi ntawm number case siv hauv cov txheej txheem luam ntawv. Raws li cov ntawv luam tawm tib lub sijhawm, tus nqi number case nrog ntau dua ntom yog ntau dua li ntawm number case nrog qis ceev.
Qhov ntom ntawm tus number case yog ntau dhau lawm, feem ntau yog vim qhov siab ntawm qhov cov xim hauv number case. Hauv cov txheej txheem luam ntawv, vim tias phau ntawv thaiv tsis tuaj yeem tsav cov xim xim uas muaj qhov ntsuas kub ntau dhau ua ke hloov mus ua ke, cov khoom sib xws xws li cov pleev xim tau tsim rau saum npoo ntawm tus number case cov menyuam, luam ntawv phaj, lossis daim pam, ua rau thaiv kev tshwm sim. Tshwj xeeb tshaj yog nyob rau hauv kev kub ceev luam ntawv los yog mem kua thinning, kev siv cov ntom ntim cov nrawm cuam tshuam ntau rau qhov tshwm sim no. Nyob rau tib lub sijhawm, thaum tus number case siab-sib xyaw ua ke nrog tus number case-tsawg, yog tias qhov sib txawv ntawm ob yog loj dhau, tus number case xim delamination yuav tshwm sim. Tus number case nrog tus ntom ntab ntab ua ke thiab tus number case nrog lub siab ntom ntom, kom cov xim ntawm tus number case saum npoo yog qhov ncaj rau tus number case nrog qhov ntom ntom, thiab xim ntawm tus number case hauv qab yog qhov ncaj rau tus number case nrog lub siab tuab. Feem ntau, qhov ntom ntawm luam ntawv number case yog nruab nrab ntawm 1g / cm3 thiab 2.25g / cm3.
Txuj Ci
Fineness hais txog qib uas tawg ntawm cov hmoov sib txawv xws li cov xim thiab cov ntxau ntawm cov kua mem hauv phau ntawv, tseem paub txog qib kev tawg. Nws qhia txog qhov loj me ntawm cov khoom sib txawv hauv tus number case thiab qib ntawm kev faib khoom faib tawm hauv phau ntawv. Qhov kawg ntawm tus number case qhia txog qhov zoo ntawm cov khoom tawg thiab cov khoom sib kis ntawm cov khoom sib txawv hauv tus number case. Qhov kawg ntawm tus number case yog txiav txim siab los ntawm qhov ntsuas ntawm txoj kev ntub dej ntawm cov xim thiab lwm cov khib nyiab los ntawm phau ntawv thiab qhov kawg ntawm tus number case tom qab nplawm thiab dov.
Tus cwj pwm zoo ntawm tus number case cuam tshuam txog qhov luam tawm, xws li rheology, fluidity thiab stability ntawm tus number case, thiab yog qhov tseem ceeb zoo ua cim. Qhov txig ntawm tus number case yog qhov tsis zoo thiab qhov kev sib txhuam yog coarse, uas tuaj yeem ua rau txhaws thaum lub sijhawm luam ntawv. Hauv kev txiav txim siab luam ntawv thiab gravure luam ntawv, nws tuaj yeem ua kev puas tsuaj rau luam ntawv phaj thiab squeegee. Ntxiv mus, vim tias qhov tsis sib xws ntawm cov xim pleev xim, lub zog ntawm tus number case xim tsis tuaj yeem ua tiav, uas cuam tshuam rau lub hwj chim xim ntawm tus number case thiab qhov ci ntawm tus number case zaj duab xis tom qab ziab.
Pob tshab
Transparency yog hais txog qib uas tus number case refracts (sib kis) teeb meem lub teeb. Transparency hauv kev luam ntawv yog hais txog qib uas cov xim tom qab ntawm cov khoom nqa tau tuaj yeem tshwm sim thaum tus number case yog tusyees coated rau hauv zaj duab xis. Thaum lub kua muag ntawm tus number case tsawg thiab cov xim tom qab tsis tuaj yeem pom tag nrho, nws yuav npog cov xim tom qab rau qee yam, yog li qhov kev ua haujlwm ntawm tus number case tseem hu ua kev zais hwj chim. Lub pob tshab ntawm tus number case yog inversely xwm yeem rau lub zog zais. Lub pob tshab yog qhia los ntawm cov tuab ntawm tus number case txheej thaum tus number case kiag li npog ib tug tom qab xim. Qhov ntau dua cov tuab tuab, qhov zoo dua cov pob tshab ntawm tus number case thiab qis dua ntawm lub zog nkaum.
Lub pob tshab yog nyob ntawm qhov sib txawv ntawm qhov ntsuas qhov hloov pauv ntawm cov xim hauv tus cwj mem thiab phau ntawv, thiab muaj feem xyuam rau kev tawg ntawm cov xim. Qhov sib txawv me me hauv qhov sib txawv ntawm qhov ntsuas qhov nruab nrab ntawm cov xim thiab phau ntawv sib txawv, qhov zoo dua qhov kev tawg ntawm cov xim hauv phau ntawv, thiab ntau dua qhov ua rau cov xim xaim.
Tshaj dhau
Glossiness yog hais txog lub peev xwm ntawm tus number case nyob rau saum npoo ntawm cov ntawv luam tawm kom pom zoo thiab tsom teeb hauv qhov kev coj ua tib yam hauv qab qhov kev tsis sib haum xeeb ntawm lub teeb tom qab tus number case nyob rau saum npoo ntawm cov ntawv luam tawm tau qhuav. Lub ntim nrog lub siab gloss zoo nkaus li kaj lug ntawm kev luam ntawv. Cov duab ci yog tsuas yog txiav txim siab los ntawm hom thiab xwm txheej ntawm phau ntawv nyob rau hauv tus number case, kev ua cov txheej txheem ua kom zoo dua qub hauv kev tsim cov kua cwj mem, thiab cov tiaj tiaj ntawm tus number case zaj duab xis tom qab ziab. Tsis tas li ntawd, lub ntsej muag xim mem kuj tseem cuam tshuam los ntawm qhov xwm ntawm cov xim hauv zaj nkauj muaj pes tsawg leeg, qhov loj thiab cov duab ntawm cov khoom me, thiab qhov sib txawv ntawm kev tawg; permeability, theem, thiab qhuav khoom ntawm tus number case; cawv ntawm dej xaum cia rau luam ntawv thiab lwm yam.
Lub teeb cauj
Lub teeb thev naus laus zis hais txog lub peev xwm ntawm tus number case yuav tsum tsis hloov nws cov xim nyob rau hauv lub teeb fluorescent. Lub teeb nrawm ntawm tus number case qhia txog qib kev fading lossis tshem tawm cov teeb meem luam ntawv hauv qab lub teeb pom. Txawm hais tias tus number case nrog lub teeb muaj zog tiv nrog lub hnub ci ntev ntev tom qab luam ntawv, qhov degree ntawm fading thiab discoloration ntawm cov ntawv luam tawm yog me me; Tus number case nrog cov tsis zoo lub teeb tsis kam yog yooj yim rau fade thiab discolor cov teeb meem luam tawm, thiab txawm tias cov xim yuav ploj tag mus. Hauv qhov muaj qhov muab kua mem kua, qib 8 yog qhov tsawg dua ntog rau cov xim tsis zoo thiab tshem tawm, thiab lub teeb tiv thaiv yog qhov zoo tshaj plaws. Lub teeb nrawm ntawm tus number case feem ntau nyob ntawm cov xim pleev xim. Lub teeb tsis kam ntawm tus number case tsis muaj kev cuam tshuam rau cov txheej txheem luam ntawv, thiab feem ntau yog cuam tshuam nrog kev siv cov txheej txheem ntawm cov ntawv luam tawm.
Kub ua hauj
Thaum tshav kub kub ua hauj lwm hais txog lub peev xwm ntawm tus number case los hloov nws cov xim thaum rhuab. Cov muaj zog thaum tshav kub kub qhia tias thaum cov ntawv luam tawm tau rhaub mus rau qhov kub dua, tus number case yuav tsis hloov xim. Qhov kub ua hauj ntawm number case feem ntau nyob ntawm hom thiab kev ua haujlwm ntawm cov xim thiab khi. Qee qhov pigments tsis tsuas yog hloov xim thaum ua kom sov, tab sis kuj hloov.
Tshuaj lom neeg
Qhov kev ua tau zoo no hais txog kev muaj peev xwm ntawm tus number case kom tsis hloov pauv ntawm cov xim thiab kev ua tau zoo nyob rau hauv kev ua los ntawm cov kua qaub, alkali, dej, dej cawv lossis lwm cov kuab tshuaj, thiab tseem paub tias yog tshuaj lom lossis tsis kam ntawm tus number case. Cov kua mem muaj cov tshuaj tiv thaiv uas muaj zog, thiab cov xim thiab number case yuav tsis hloov nyob rau hauv kev ua los ntawm cov kua qaub, alkalis thiab lwm yam. Cov tshuaj lom neeg tawm ntawm tus number case yog txiav txim siab los ntawm hom thiab kev ua haujlwm ntawm cov xim thiab phau ntawv, thiab muaj feem xyuam rau lub xeev ntawm kev sib xyaw ntawm cov xim thiab phau ntawv tiv thaiv, thiab muaj feem xyuam nrog kev ruaj ntseg ntawm tus number case.
