Cov lus nug ntawm "dab tsi yog cov khoom siv zoo tshaj plaws rau scraper" yuav tsum muaj kev xav zoo los ntawm ntau qhov ntev. Tam sim no, kev ua lag luam muaj ntau yam khoom siv scraper, suav nrog tab sis tsis txwv rau cov hlau tsis muaj steel, carbon steel, hlau alloy, yas, roj hmab, thiab ceramics, txhua tus nrog nws cov khoom tshwj xeeb thiab cov xwm txheej.
Ua ntej, stainless hlau scrapers yog dav nrov vim lawv zoo heev corrosion kuj thiab hnav tsis kam. Hauv kev lag luam uas muaj kev nyiam huv heev,
xws li kev ua zaub mov, tshuaj, thiab tshuaj, stainless hlau scrapers xyuas kom cov khoom nyob twj ywm uncontaminated.
Lawv cov hardness siab thiab ntev lifespan kuj txo cov zaus hloov thiab tu nqi. Feem ntau, 304 lossis 316 stainless hlau yog cov kev xaiv ntau, haum rau cov chaw ib puag ncig thiab ib puag ncig corrosive heev, feem. Thib ob, carbon steel scrapers paub txog lawv lub zog siab thiab hardness, haum rau cov ntawv thov uas xav tau kev kub siab thiab hnav, xws li hlau ua thiab ua haujlwm ntoo. Txawm li cas los xij, cov hlau tsis tshua muaj xeb thiab yuav tsum tau kho qhov chaw xws li galvanizing lossis chrome plating los txhim kho corrosion.
Tsis tas li ntawd, alloy steel scrapers, los ntawm kev ntxiv lwm cov ntsiab lus xws li chromium, npib tsib xee, thiab molybdenum, ntxiv dag zog rau lawv cov kev ua tau zoo, suav nrog hardness, toughness, thiab tshav kub tsis kam, ua rau lawv haum rau ntau qhov chaw ua haujlwm. Yas thiab roj hmab scrapers feem ntau yog siv nyob rau hauv daim ntawv thov uas yuav tsum tau scraping quab yuam tsis siab, tab sis khawb qhov chaw ua hauj lwm yuav tsum tau zam, xws li kev ua cov ntaub ntawv xws li iav thiab yas films.
Lawv yog cov tsawg- tus nqi thiab lub teeb yuag, tab sis lawv cov kev hnav tsis zoo kuj tsis zoo. Thaum kawg, ceramic scrapers, nrog lawv cov hardness tsis tshua muaj siab thiab hnav tsis kam, tuav ib txoj hauj lwm irreplaceable nyob rau hauv precision machining teb, xws li semiconductors thiab optical Cheebtsam. Txawm li cas los xij, lawv yog nkig thiab tawg yooj yim, yuav tsum tau ceev faj tuav. Hauv kev xaus, xaiv cov khoom siv scraper uas tsim nyog tshaj plaws yuav tsum muaj kev xav txog ntawm cov ntawv thov tshwj xeeb, kev ua haujlwm, thiab cov nqi siv nyiaj. Hauv kev lag luam feem ntau nrog cov kev xav tau siab rau kev nyiam huv thiab kev tiv thaiv corrosion, stainless hlau scrapers yog thawj qhov kev xaiv; thaum nyob rau hauv daim ntaub ntawv xav tau kev kub siab thiab hnav, carbon steel los yog alloy steel scrapers yog tsim nyog; rau lub teeb yuag, tsis yog - daim ntawv thov abrasive, yas lossis roj hmab scrapers txaus; thiab nyob rau hauv lub teb ntawm precision machining, ceramic scrapers qhia tshwj xeeb zoo.
