Cov kev ceev faj
1. Puas muaj kev sib raug zoo ntawm kev kho ceev ntawm cov kua nplaum tsis muaj duab ntxoo thiab qhov zoo ntawm cov kua nplaum? SGS Daim Ntawv Qhia Txog Qhov Zoo ntawm Cov Khaub Ncaws Tsis Muaj Duab Ntxoo
Qhov curing ceev ntawm shadowless kua nplaum, tshwj xeeb tshaj yog nyob rau hauv txoj hauj lwm ceev, yeej ib txwm yog cov ntaub ntawv uas cov neeg siv khoom muaj kev txhawj xeeb ntau dua. Muaj ntau ntau yam los ntsuas qhov zoo ntawm cov kua nplaum tsis muaj duab ntxoo: lub sijhawm tso, qhov tob tob, lub zog, thiab kev ua kom yooj yim ntawm cov yeeb yaj kiab yog txhua yam ntawm kev ntsuas qhov zoo ntawm cov kua nplaum tsis muaj duab ntxoo. Peb ntseeg hais tias qhov ceev ntawm qhov chaw ceev, qhov ntau dua qhov kev ntxhov siab sab hauv tsim thaum cov kua nplaum kho. Qhov no tuaj yeem ua rau lub phaj aluminium poob. Feem ntau, qhov chaw ceev yog 6 mus rau 10 vib nas this. Yog li ntawd, nws yog qhov tsis ncaj ncees lawm los txiav txim qhov zoo ntawm shadowless kua nplaum nkaus xwb raws li kev kho ceev.
2. Qhov ntau npaum li cas yog qhov zoo dua thaum sib txuas?
Shadowless kua nplaum tsis yog qhov ntau npaum li cas, qhov zoo dua. Cov kev sim qhia tau hais tias lub thinner lub nplaum txheej, lub zog ntau dua. Feem ntau hais lus, lub thickness ntawm zaj duab xis yuav tsum tsis txhob ntau tshaj 0.2 microns.
3. Ntau tus neeg tau txais kev pab tau pom tias cov nplaum tsis muaj duab ntxoo qee zaum ua kom dawb thaum siv cov nplaum tsis muaj duab ntxoo. Yuav ua li cas whitening phenomenon ntawm shadowless nplaum yuav sai thiab raug kuaj?
Qhov tshwm sim ntawm cov kua nplaum uas tsis muaj duab ntxoov ntxoo yog ib qho teeb meem tshwm sim, tab sis vim tias qhov tshwm sim whitening tsis loj heev thiab cov yeeb yaj kiab kuj yog nyias, feem ntau nws nyuaj rau nrhiav. Qhov teeb meem no tshwm sim ntau dua los yog tsawg dua nyob rau hauv cov iav-rau-hlau shadowless kua nplaum ntawm lub khw. Siv lub khob iav, tso cov kua nplaum rau ntawm nws, thiab muab tso rau hauv qab lub teeb rau 12 feeb, ces muab nws tawm thiab saib, kom pom qhov tshwm sim ntawm cov xim dawb ntawm cov kua nplaum uas tsis muaj duab ntxoo tuaj yeem tshawb pom sai. Lub degree ntawm whitening yog ncaj qha ntsig txog lub thickness ntawm zaj duab xis. Qib ntawm cov kua nplaum dawb tsis muaj dab tsi ua rau lub zog!
4. Lub viscosity ntawm shadowless kua nplaum?
Thaum cov kua txav los ntawm lub zog sab nraud, qhov ntsuas ntawm kev sib txhuam ntawm nws cov molecules hu ua viscosity. Qhov kev sib txhuam ntau dua, qhov viscosity ntau dua; qhov me me ntawm kev sib txhuam tsis kam, qhov qis dua qhov viscosity. Hauv International System of Units, chav tsev ntawm viscosity yog mPa.s. Lub viscosity ntawm dej yog 1.14 mPa.s.
5. Puas yog qhov viscosity qis dua, lub zog qis dua?
Tsis muaj kev sib raug zoo ntawm cov viscosity thiab lub zog ntawm cov shadowless kua nplaum. Yog hais tias nws yog tsis ncaj ncees lawm to taub viscosity raws li lub zog, nws yog ib qho kev to taub yuam kev.
6. Cov tshuaj muaj pes tsawg leeg ntawm cov kua nplaum tsis muaj duab ntxoo yog dab tsi?
Tsim los ntawm oligomer, monomer, photoinitiator thiab auxiliary tus neeg sawv cev;
7. Kev ua tau zoo ntawm shadowless kua nplaum:
Kev kho sai sai thiab tswj tau cov tshuaj tiv thaiv; hnyav-dawb thiab tsis muaj kuab paug; haum rau kev ua haujlwm tsis siv neeg; Kev sib raug zoo ntau yam, muaj zog sib koom ua ke, thiab thaj chaw siv dav; zoo heev optical kev ua tau zoo; Tsis muaj xim thiab pob tshab colloid, tom qab kho pob tshab tus nqi" 90%; huab cua tsis kam Zoo heev, tsis muaj yellowing; curing txoj cai thiab curing tej yam kev mob ntawm shadowless kua nplaum; photoinitiator (photosensitizer) nyob rau hauv shadowless kua nplaum absorbs ultraviolet lub teeb nyob rau hauv ultraviolet hluav taws xob los tsim active dawb radicals los yog cations, thiab pib monomer polymerization thiab crosslinking Nws reacts nrog branching tshuaj ua rau cov nplaum hloov los ntawm cov kua rau cov khoom nyob rau hauv ob peb vib nas this; cov kua nplaum tsis muaj duab ntxoo yuav tsum tau kho nyob rau hauv hluav taws xob ultraviolet nrog lub wavelength ntawm 200nm ~ 400nm;
8. Dab tsi yog qhov txawv ntawm cov kua nplaum uas tsis muaj duab ntxoo thiab lwm cov kua nplaum?
Cov kua nplaum tsis muaj duab ntxoo tau pib teeb tsa hauv lub teeb ultraviolet rau 1-5 vib nas this, thiab kev sib txuas tuaj yeem ua tiav hauv 20-30 vib nas this. Tom qab irradiation, nws tuaj yeem ncav cuag lub zog siab dua, uas tuaj yeem ua tau raws li cov kev xav tau ntawm cov atherosclerosis ntawm cov kab ntau lawm; thib ob-tiam acrylic structural nplaum 1-10 Lub zog siab tshaj plaws tuaj yeem ncav cuag li ntawm 24 teev tom qab pib kho; chav kub curing epoxy structural adhesives tuaj yeem kho tsis pub dhau 10 mus rau 120 feeb, thiab lub zog siab tshaj plaws tuaj yeem ncav cuag li ntawm 7 teev.
