Suab puam abrasive
Cov abrasive ntawm sandpaper yog cov khoom sib tsoo ntawm cov xuab zeb, uas yog siv rau kev sib tsoo thiab polishing cov khoom ntawm cov khoom. Cov khoom siv hluav taws xob ib txwm muaj xws li cov khoom siv hluav taws xob tau siv cov duab alumina, thiab lwm yam los tshem tawm cov xeb, thiab pleev xim, thiab cov chaw du. Los ntawm cov ntaub ntawv, muaj alumina bandpaper, silicon carbide sandpaper, thiab lwm yam; Los ntawm daim ntawv thov, muaj kev sib tsoo qhuav sandpaper, ntub kev sib tsoo cov sandpaper, thiab lwm yam; Los ntawm grit loj, muaj cov coarse sandpaper, zoo nkauj xuab zeb, thiab lwm hom. Los ntawm nws cov nyhuv sib tsoo, cov abrasive ntawm cov xuab zeb pab kom ua tiav txoj kev ua kom zoo thiab kev kho saum npoo av ntawm ntau yam ntaub ntawv.
I. Keeb kwm evolution ntawm daim ntawv abrasive
Xws lione of the earliest tool innovations of mankind, abrasive paper can be traced back to 13th-century China. Raws li "keeb kwm ntawm Yuan dynasty", istisans nyob rau hauv yuan dynasty twb tau paub li cas cov ntoo ntoo kua ntoo thiab muab tso rau saum npoo ntawm parchment los ua cov txheej txheem txheej thaum ub. Qhov no "proto -} ovasive ntawv" tau siv cov lacishingware, ua rau muaj kev txawj ntse ntawm Suav ancient hauv cov ntaub ntawv sib xyaw.
Cov kev lag luam kev hloov pauv tau hais txog ib qho leap hauv sandpaper technology:
Xyoo 1830,John GoodyearNtawm Birmingham, UK, sib xyaw Quartz xuab zeb nrog cov roj linseed los tsim cov duab khau thawj thiab tsim cov txheej txheem ntau lawm. Minnesota txoj tuam txhab kev txiav thiab tsim tawm hauv xyoo 1902, tau pib tsim los txhim kho Corundum Mines tab sis hloov pauv mus rau hauv cov suab paj nruag loj.
Xyoo 1921, nws tsim lub waterproofSandpaper Ntub Ntab Tshuab, uas tau siv cov txheej txheem resin tshwj xeeb los tswj cov nplaum ntawm cov khoom muaj abrasive hauv qab, kos cim rau hauv automalive painting thev naus laus zis. Thaum lub sijhawm Tsov Rog Thoob Ntiaj Teb Zaum 2, Sandpaper Technology yog kev ua kom zoo ntxiv. German cov cav tsim kho super {{1000 precisionandpaper (nrog griting loj ntawm cov twj pib, ua tiav micron precision.
Kawm cov sandpaper technator technology muaj surpassed kev nkag siab ib txwm:
3M's Cubitron II Ceramic Abrasive TshuabSiv cov qauv muaj tswv yim meej meej cov ntsiab lus tej zaum muaj peb zaug uas muaj peb zaug ntev dua li cov abree aluminium.
TusNano {- nplai pob zeb diamond pob zeb diamondTsim los ntawm Nyiv cov tuam txhab Norritake tuaj yeem ua tiav daim iav polishing ntawm cov khoom siv nyuaj, nrog qhov chaw ntawm qhov chaw nyob ntev dua li ra 0.02 μm.
Ii. Kev tshawb fawb paub tseeb: cov archise zoo ntawm cov tshuab abrasive
Cov Tshuab Abrasive niaj hnub rau cov suab paj nruag nthuav tawm ntau - dhuav cov yam ntxwv ntawm cov yam ntxwv ntawm cov yam ntxwv
