Koj puas to taub qhov txawv ntawm cov ntawv xuab zeb?

Kev faib tawm ntawm cov ntawv xuab zeb yuav tsum muaj kev txiav txim siab zoo ntawm peb qhov loj: cov khoom siv abrasive, cov khoom siv rov qab, thiab daim ntawv thov scenario. Cov peb yam no suav nrog txiav txim siab ntawm daim ntawv xuab zeb lub peev xwm txiav, kev ua kom sov dissipation, thiab siv ntau yam.

1. Cov Khoom Siv Abrasive: Cov khoom siv tshuaj txiav txim siab txiav kev ua haujlwm.
• Silicon Carbide Sandpaper: Cov xim dub abrasive muaj cov duab peb sab pyramid thiab nws tus kheej zoo heev -nplaum zog, tuav lub ntse ntse thoob plaws hauv kev sib tsoo. Nws cov thermal conductivity siab ua rau nws zoo tagnrho rau cov hlau tsis yog -ferrous xws li aluminium alloys thiab ceramics, tshwj xeeb tshaj yog tsim rau cov txheej txheem ntub dej sib tsoo. Piv txwv li, nyob rau hauv kev ua ntawm aerospace aluminium alloy Cheebtsam, silicon carbide sandpaper ua ke nrog ntub sib tsoo tuaj yeem tswj tau qhov roughness hauv qab Ra0.8um.
• Aluminium Oxide Sandpaper: Cov xim liab abrasive paub txog nws lub siab toughness thiab tawg tsis kam, haum rau ntxhib thiab zoo sib tsoo ntawm cov hlau tawv xws li hlau thiab stainless hlau. Hauv automotive sheet hlau kho, P180-P400 grit aluminium oxide sandpaper tuaj yeem ua tiav cov txheej txheem gradient los ntawm kev tshem tawm cov xim qub rau saum npoo.
• Pob zeb diamond Sandpaper: Raws li tus neeg sawv cev ntawm superhard abrasives, nws cov microscopic txiav ntug ntom tuaj yeem ncav cuag ntau pua lab ib square centimeter. Nyob rau hauv daim iav kho qhov muag polishing, nws tuaj yeem txo qhov roughness ntawm Ra0.01um, tab sis tus nqi yog 3-5 npaug siab dua li cov ntawv xuab zeb.
• Garnet Sandpaper: Cov ntxhia pob zeb hauv av no muaj cov yam ntxwv ntawm kev txiav maj mam thiab feem ntau yog siv rau cov xuab zeb zoo ntawm cov ntoo mos xws li ntoo thuv thiab cedar, tiv thaiv fiber ntau tearing los ntawm kev txiav ntau dhau.

2. Substrate Structure: Lub cev muaj zog cuam tshuam rau kev ua haujlwm ruaj khov
• Ntawv Substrate: Siv high-lub zog latex ntawv los yog kraft ntawv, uas yog tus nqi qis tab sis muaj kev tiv thaiv tsim kua muag tsawg . 3M's tsim electrostatic abrasive txheej txheej txheem txhim kho abrasive faib uniformity los ntawm 40%, txhim kho kev ua tau zoo.
• Ntaub Substrate: Polyester fiber ntau substrate muaj lub zog tensile zoo heev thiab tuaj yeem tiv taus lub zog centrifugal uas tsim los ntawm siab -kev sib hloov ceev hauv robotic automated sib tsoo. Bosch E466 series sanding discs nrog velvet thaub qab ua tiav cov plua plav tshem tawm tau zoo los ntawm kev tsim 8-qhov, txuas lawv lub neej kev pab cuam los ntawm 2-3 zaug piv rau cov ntawv xuab zeb.
• Daim txhuam cev Substrate: Polyurethane sponge carrier muab cov ntawv xuab zeb zoo yooj, ua tiav ntau dua 98% kev ua raws hauv cov txheej txheem nkhaus. Kraftwell YS3239 sponge sandpaper teeb, nrog nws cov qauv tsim grit (400-}2000 grit), tso cai rau daim iav zoo li ua tiav ntawm cov rooj tog ntoo.

3. Daim Ntawv Thov: Cov txheej txheem yuav tsum tau tsav cov khoom tsim tawm tshiab
• Dry Sandpaper: Synthetic resin binders muab cov khoom tiv thaiv zoo tshaj -clogging, tso cai rau kev ua haujlwm tsis tu ncua rau ntau tshaj 2 teev thaum lub sijhawm sib tsoo ntawm cov hlau tsis muaj kev hloov pauv. Japanese Riken qhuav sandpaper siv nano- theem tiv thaiv - zoo li qub txheej tshuab los txo cov plua plav adsorption qis dua 5%.
• Cov Ntawv Sandpaper ntub dej: Kev sib xyaw ua ke ntawm cov kua roj vanish thiab silicon carbide abrasive ua rau nws muaj dej- tiv taus. Hauv kev kho cov xim tsheb, thaum siv nrog cov dej ntws, kev ua haujlwm kub tuaj yeem tswj tau li ntawm 40 degree, tiv thaiv thermal deformation zoo . 3M 401Q ntub xuab zeb siv cov qauv tsim microporous los ua kom cov dej txias nkag los ntawm 60%.
• Daim txhuam cev Sandpaper: Nws peb - cov qauv tsim ua rau nws muaj txiaj ntsig zoo hauv kev ua cov khoom tsis sib xws. German Hermes sponge sanding blocks, los ntawm kev ceev gradient tswj thev naus laus zis, ua tiav kev hloov pauv ntawm kev sib tsoo ntxhib mus rau kev sib tsoo zoo. Hauv kev ua cov khoom siv titanium alloy rau cov khoom siv kho mob, nws tuaj yeem tswj tau qhov roughness uniformity nyob rau hauv ± 0.2um.
