Ob qho "dry erase marker" thiab "whiteboard marker" yog hais txog cov cwj mem uas siv cov cwj mem tshem tawm uas tsim los rau cov slick, tsis muaj qhov ntxeem tau xws li whiteboards.
Ink Composition thiab Chemistry
Whiteboard/dry-erase inks yog tsim nrog silicone polymers raug tshem tawm nyob rau hauv volatile, cawv-raws li kuab tshuaj. Lub polymer tiv thaiv tus number case los ntawm kev sib txuas rau saum npoo, ua kom yooj yim so, thaum cov kuab tshuaj evaporate sai sai kom qhuav sai.
Nto Compatibility
Cov cim no ua tau zoo tshaj plaws ntawm cov tsis ntxeem tau substrate, uas tsis tuaj yeem nqus tau tus cwj mem. Qhov saum npoo du tso cai rau cov kua nplaum polymer-coated ua raws li lub rooj tsavxwm nto thiab so kom huv tau yooj yim.
Erasability thiab Performance
Cov kev ntsuas kev ua haujlwm tseem ceeb suav nrog kev tshem tawm (tsis muaj staining), tiv thaiv "ghosting" (faint residual marks), ink flow sib xws, thiab lub sij hawm ziab. Nyob rau tib lub sijhawm, rov sau dua ntawm cov ntawv qib qis dua tsim cov kab mob me me uas cuam tshuam rau tus cwj mem, ua rau muaj kev puas tsuaj thiab ua rau muaj kev puas tsuaj.
Lub tswv yim hom thiab kab Precision
Marker tip geometry dictates kab dav thiab kev sau ntawv:
Bullet: uniform, ~ 1-2 hli kab, zoo tagnrho rau kev sau txhua hnub
Chisel: adjustable dav (dav los yog nplua), zoo rau cov lus thiab tseem ceeb
Fine / Ultra-Fine: meej, ~ 0.7 hli kab, haum rau cov ncauj lus kom ntxaws lossis cov ntawv me me
Ergonomics thiab Design
Cov cim niaj hnub no muaj kev txhim kho ergonomic:
Barrel shapes (piv txwv li, squircle designs) uas tiv thaiv dov thiab txhim kho tuav
Cap retention systems (snap-fit, click-on) kom txo tau lub hau poob
Cov kaus mom hlau nplaum los yog cov thoob rau qhov yooj yim board-side cia
FAQ
Q1: Puas yog cov cim pov tseg qhuav thiab cov ntawv teev lus dawb zoo ib yam?
A: Yog. Ob nqe lus piav qhia cov cwj mem nrog cov cwj mem uas tuaj yeem tsim tau rau cov chaw tsis muaj qhov ntxeem tau zoo li whiteboards.
Q2: Kuv puas tuaj yeem siv whiteboard markers ntawm iav lossis acrylic?
A: Yog lawm. Cov cim no ua haujlwm ntawm txhua qhov slick, tsis muaj qhov ntxeem tau - suav nrog iav, acrylic, thiab melamine - vim tias tus number case zaum ntawm qhov chaw es tsis yog nqus.
Q3: Vim li cas kuv cov qhab nia tso tseg tsis pom dab tsi?
A: Ghosting tshwm sim thaum lub rooj tsavxwm txheej txheej degrades-microscopic craters ntxiab number case residues, ua rau lawv nyuaj rau tshem tawm tag nrho. Siv cov plooj (porcelain) lossis iav boards tuaj yeem txo cov nyhuv no.
Q4: Puas yog cov kua nplaum qhuav qhuav puas muaj kev nyab xeeb thiab tsis muaj ntxhiab tsw?
A: Yog. Tsis muaj ntxhiab tsw thiab tsis muaj tshuaj lom, haum rau siv hauv chav kawm thiab chaw ua haujlwm.
