Invisible Fixing Solutions rau Acrylic Supermarket Shelving
Lub khw muag khoom txee feem ntau siv hmoov-coated steel uprights thiab hlau decks. Cov tuav cov khoom sib nqus tau kos rau hauv cov txee acrylic lossis kos npe tso cai rau tag nrho cov zaub kom txuas cov hlau nplaum yam tsis pom cov khoom siv. Ib qho qauv tsim: kev txhaj tshuaj pwm ib lub hnab ntim hauv qab ntawm lub txee acrylic, ntxig cov hlau nplaum neodymium (N35, 10mm txoj kab uas hla x 3mm tuab), thiab muab khi nrog lub hau yas nyias. Plaub cov hlau nplaum no muab lub zog tuav ntawm 20-30kg ib lub txee, txaus rau cov khoom muag muag.
Rau cov khoom hnyav-cov dej num (piv txwv li, cov txee dej haus tuav 50kg), peb siv cov hlau nplaum loj (20mm x 5mm NdFeB N45) embedded nyob rau hauv steel khob uas concentrate flux mus rau sab nraum qab phaj. Lub khob steel kuj tiv thaiv cov hlau nplaum los ntawm kev cuam tshuam thaum lub sijhawm teeb tsa.
Roj Hmab-Coated Magnets vs. Metal Cup Assemblies for Slide Resistance
Roj Hmab-coated hlau nplaum (Santoprene TPV lossis silicone) muab kev sib txhuam siab, tiv thaiv cov duab los ntawm zawv zawg ntawm ntsug lossis slanted. Cov roj hmab kuj tseem tiv thaiv cov pleev xim los yog hmoov-coated tiav los ntawm khawb. Cov coefficient ntawm kev sib txhuam: roj hmab vs. pleev xim rau steel=0.6-0.8, piv rau liab qab hlau nplaum vs. steel=0.1-0.2. Rau cov khw muag khoom kos npe mounted rau sab phab ntsa los yog slanted gondolas, roj hmab -coated hlau nplaum yuav tsum tau tiv thaiv creeping.
Hlau khob sib dhos (countersunk neodymium hlau nplaum nias rau hauv lub khob steel) muab siab dua shear quab yuam tsis kam tab sis qis kev sib txhuam. Lawv tsim nyog rau qhov chaw kab rov tav (piv txwv li, tuav lub hauv paus rau lub txee). Lub khob steel nce qhov sib nqus qhov projection los ntawm 30-50% ntawm qhov kev sib cuag, tso cai rau kev sib dhos me me.
Kev sib piv ntawm cov khoom sib nqus rau cov khoom muag:
| Hom | Tuav Force (kgf ib 20mm dia) | Kev sib txhuam (μ) | Scratch Risk | Kev siv zoo tshaj plaws |
|---|---|---|---|---|
| NdFeB (tsis muaj khob, tsis muaj roj hmab) | 8-10 | 0.1-0.2 | Siab | Kev siv ib ntus xwb |
| Roj hmab-coated NdFeB (Santoprene) | 5-7 | 0.6-0.8 | Tsis muaj | Vertical signage, pleev xim rau saum npoo |
| Hlau khob + NdFeB (countersunk) | 12-15 | 0.1-0.2 | Tsawg (steel khob tiv thaiv hlau nplaum) | Kab rov tav txee mounts |
| Lub khob steel + roj hmab sab nraud | 10-12 | 0.5-0.7 | Tsis muaj | Premium zaub, siab load ntsug |
Threaded Holes vs. Countersunk Qhov rau Installation
Rau cov khoom uas yuav tsum tau tshem tawm tsis tu ncua (xws li, raws caij nyoog kos npe), peb muab cov hlau nplaum tuav nrog threaded M3, M4, los yog M6 studs. Lub stud yog screwed rau hauv cov zaub rov qab, thiab cov hlau nplaum txuas rau cov hlau ncej. Txhawm rau tshem tawm, tag nrho cov zaub nqa tawm. Kev txhim kho yuav tsum tau drilling thiab tapping cov khoom siv.
Rau qhov mus tas li lossis ib nrab- qhov txuas mus tas li, cov qhov sib tsoo yog siv. Ib tug flathead ntsia hlau hla los ntawm cov hlau nplaum sib dhos rau hauv cov zaub. Cov hlau nplaum yog ces yaug nrog cov zaub saum npoo. Qhov no yog ib txwm muaj rau hnyav acrylic txee qhov twg tub sab lossis tsoo tsoo-tawm yog ib qho kev txhawj xeeb.
Rau daim ntawv thov nplaum nplaum (piv txwv li, ib ntus kev txhawb nqa), cov tuav hlau nplaum nrog 3M VHB daim kab xev ua ntej - siv tau. Tev thiab lo rau cov zaub rov qab. Peel quab yuam yog 20-30 N / cm².
Kev sib xyaw ua kom pom kev zoo nkauj nrog cov kev xaiv nto plating
Rau siab -kawg cov khw muag khoom pom qhov pom cov hlau nplaum (piv txwv li, sib nqus kaw ntawm cov khoom siv nyiaj txiag), cov hlau nplaum pom saum npoo yuav tsum phim cov khoom tiav. Peb muab:
Nickel plating (ci nyiaj) - txheem tiav, muaj kev cuam tshuam.
Nickel dub lossis zinc dub - matte tsaus, zais av.
Kub plating (zoo nkauj) - rau cov khoom siv khoom kim heev.
Stainless hlau khob ( txhuam tiav) - kev lag luam saib.
Rau kev siv tsis pom, txheej txheem nickel lossis roj hmab txheej yog txaus. Tag nrho cov ntaub ntawv yog raws li RoHS.
Rau cov khw muag khoom lag luam muag khoom lag luam nrhiav kev cai sib nqus cov tuav thiab cov hauv paus - suav nrog tshwj xeeb rub quab yuam, qib roj hmab (FDA-raws li Santoprene rau kev sib cuag zaub mov), thiab kev cai xov ntau thiab tsawg - thov mus saib peb Lub Chaw Haujlwm & Lag Luam Magnets lossis Magnetic Holder & Base cov nplooj ntawv khoom ntawm peb lub vev xaib.
Txhawm rau thov cov qauv ntawm cov roj hmab-coated hlau nplaum lossis steel khob sib dhos rau koj qhov system txee, hu rau peb pawg neeg muag khoom. Peb muab pub dawb rub quab yuam kuaj ntawm koj cov khoom siv duab tiag tiag.
Cov lus nug nquag
Q: Cov roj hmab puas tuaj yeem- cov hlau nplaum coated tuaj yeem siv sab nraum zoov (UV raug, los nag)?
A: Yog, yog tias Santoprene TPV (thermoplastic vulcanizate) siv. Standard silicone roj hmab degrades nyob rau hauv UV. Qhia meej UV- ruaj khov Santoprene rau sab nraum zoov kos npe. Peb muab 3-xyoo UV tiv thaiv warranty.
Q: Dab tsi yog qhov siab tshaj plaws kev khiav hauj lwm kub rau cov hlau nplaum tuav nyob rau hauv lub tub yees tso saib?
A: Neodymium magnets in rubber coating: -40°C to 80°C. For freezer displays (-20°C to -30°C), standard N35 grade works fine. Do not exceed 80°C (e.g., near hot food display lights). Use SmCo holders for >80 degree.
Q: Kuv yuav xam pes tsawg tus tuav hlau nplaum kuv xav tau rau 1m x 0.5m acrylic txee tuav 10kg?
A: Kev nyab xeeb yam ntawm 4x. Yuav tsum tuav lub zog tag nrho=40kg. Yog tias txhua tus roj hmab -coated hlau nplaum (20mm dia) muab 6kg ntsug rub, koj xav tau 7 hlau nplaum. Ntxiv 2 cov hlau nplaum ntxiv yog tias shear load (piv txwv li, tsoo los ntawm lub tawb nqa khoom). Peb muab ib daim ntawv qhia kev suav.
