1.Dab tsi yog cov khoom pov thawj ntawm cov txheej txheem?
Txheej Hardness: Lub peev xwm los tiv thaiv indentation lossis khawb los ntawm cov khoom tawv.
Txheej Toughness: Muaj peev xwm tiv thaiv tawg thiab tev.
Txheej Adhesion rau Substrate: Txawm tias cov txheej txheej tawm tag nrho thaum khawb.
Deg Lubricity: Cov npoo du tsis tshua muaj kev khawb.
2.Dab tsi yog cov ntsiab lus thiab cov txheej txheem rau kev kuaj cwj mem hardness?
Lub hauv paus ntsiab lus: Ib cov cwj mem uas paub txog hardness (los ntawm softest 6B mus rau hardest 9H) yog siv los khawb cov coated nto kom pom seb puas muaj khawb mus tas li.
"Qib" qhia qhov siab tshaj plaws mem hluav hardness uas qhov kev xeem yuav dhau. Piv txwv li:
Ordinary polyester txheej: Feem ntau F ~ H.
High - zoo polyester / silicone - hloov polyester: tuaj yeem ncav cuag H ~ 2H.
PVDF (fluorocarbon) txheej: Feem ntau nyob rau hauv H ~ 3H ntau yam, tau txais txiaj ntsig los ntawm nws qhov zoo heev toughness thiab hardness.
High abrasion-resistant coatings tshwj xeeb (xws li abrasion-resistant polyester, plastisol): Tej zaum yuav ncav cuag 2H ~ 4H+, tab sis ntau dhau hardness yuav txia yooj.
Nco tseg: Pencil hardness yog qhov taw qhia tseem ceeb rau kev ntsuam xyuas khawb tsis kam, tab sis tsis yog tib qho xwb.
3.Dab tsi yog cov ntsiab lus thiab qib sawv cev ntawm Taber abrasion resistance test / drop test?
Lub hauv paus ntsiab lus: Cov txheej txheej saum npoo yog rubbed nrog cov txheej txheem abrasives (xws li kev sib tsoo log lossis pob zeb) nyob rau hauv qhov kev ntsuas siab thiab ceev.
"Qib" qhia: Qhov no feem ntau qhia txog cov voj voog uas yuav tsum tau hnav ib lub thickness ntawm txheej, los yog qhov poob loj (mg) tom qab ib qho kev voj voog. Cov nqi siab dua qhia tau zoo dua puas tsuaj / khawb tsis kam.
4.Dab tsi yog lub hauv paus ntsiab lus thiab kev ntsuam xyuas ntawm kev kuaj kev puas tsuaj?
Standard: Feem ntau siv rau cov khoom vaj huam sib luag.
Lub hauv paus ntsiab lus: Rubbing lub coated nto rov qab thiab tawm nrog ib daim ntawv strip ntawm ib yam khoom tshwj xeeb.
"Qib" qhia tus naj npawb ntawm rubs yuav tsum tau ua ntej lub substrate qhia pom khawb. High-cov khoom siv zoo yuav tsum tau ntau pua rubs lossis ntau dua.
5.Kuv yuav tau txais lossis qhia meej txog "theem" kuv xav tau li cas?
Tshawb xyuas cov qauv ntaub ntawv lossis cov ntaub ntawv qhia kev:
Thov kom ntxaws TDS los ntawm cov xim -coated coil chaw tsim tshuaj paus. Cov no feem ntau teev cov khoom tseem ceeb xws li mem hluav hardness, abrasion resistance (Tabè tus nqi), thiab qib adhesion.
Xaiv cov khoom thiab cov qauv raws li qhov kawg - siv:
Architectural ru tsev / phab ntsa panels: tsom rau adhesion, yoog raws (T- khoov), thiab ntev - huab cua tsis kam; ib tug cwj mem hardness nyob ib ncig ntawm H qib yog feem ntau txais.
Cov khoom siv vaj huam sib luag (xws li, lub tub yees, lub tshuab ntxhua khaub ncaws): Yuav tsum muaj qhov siab heev ntawm kev khawb thiab kev puas tsuaj; feem ntau qhia cov cwj mem nruj nruj (Ntau dua lossis sib npaug rau 2H) thiab RCA kev puas tsuaj.
Hlau rooj tog / kho kom zoo nkauj sab hauv: Yuav tsum muaj kev xav zoo thiab ua haujlwm rau txhua hnub khawb; cwj mem hardness thiab tsos yog qhov tseem ceeb sib npaug.
Khoom noj khoom haus thiab dej haus cov kaus poom, ntim khoom: Kev khawb thiab kev puas tsuaj yog qhov yuav tsum tau ua, ua ke nrog cov tshuaj tiv thaiv thiab corrosion kuj.
