Cov hlaws iav qhia tau tias "zoo rau ntawm qhov chaw" ntau dua li ntau lwm yam khoom siv abrasives, xws li alumina, silicon carbide, thiab steel grit. Cov yam ntxwv no feem ntau yog vim nws cov khoom siv lub cev thiab tshuaj lom neeg sib txawv. Qhov zoo rau ntawm qhov chaw ntawm cov hlaws iav yog pom tseeb hauv lub peev xwm los ntxuav lossis txhuam cov chaw kom zoo thaum txo qhov kev puas tsuaj rau daim ntawv ua haujlwm nws tus kheej.
Cov hauv qab no yog ob peb yam tseem ceeb uas ua rau muaj qhov xwm txheej no:
1. Cov Duab thiab Cov Qauv: Spherical vs. Angular
- Cov Hlua Iav Spherical: Cov hlaws iav muaj lub duab kheej kheej. Thaum lub sijhawm xuab zeb rau ntawm cov khoom ua haujlwm, lawv tsim cov ntsiab lus sib cuag. Hom kev sib cuag no ua rau muaj kev ntxhov siab tsawg. Qhov kev ua zoo ib yam li "tapping" lossis "dov", feem ntau yog pab tshem tawm cov khoom tsis zoo ntawm qhov chaw, xws li cov txheej xeb thiab cov xim pleev xim qub, yam tsis nkag mus tob rau hauv cov khoom ua haujlwm.
- Cov Khoom Siv Sib Tsoo Angular: Qhov sib txawv, cov khoom siv sib tsoo xws li xim av corundum, hlau grit, thiab tooj liab slag feem ntau muaj cov npoo ntse thiab tsis sib xws. Thaum siv rau sandblasting, lawv ua rau cov kab lossis cov ntsiab lus sib cuag, tsim kev ntxhov siab hauv zos. Qhov no zoo ib yam li ntau lub chisels me me txiav qhov chaw.
Cov duab kheej kheej ntawm cov hlaws iav zoo tiv thaiv kev txiav thiab pitting los ntawm cov npoo ntse, yog li ntawd txo cov khoom siv hnav thiab txo qhov nce ntawm qhov roughness ntawm qhov chaw.
2. Khoom siv Hardness: Nruab nrab thiab Tunable
Qhov nyuaj ntawm cov hlaws iav feem ntau yog txij li 6 txog 7 ntawm Mohs nplai. Qib nyuaj no txaus kom tshem tawm cov khoom tsis huv ntawm qhov chaw, xws li xeb (nrog Mohs hardness ntawm 4 - 5) thiab cov xim pleev xim qub. Tib lub sijhawm, nws qis dua lossis sib piv rau qhov nyuaj ntawm ntau cov khoom siv hlau.
3. Kev Txhaj Tshuaj Peening Strengthening Effect
Qhov cuam tshuam ntawm cov hlaws iav rau ntawm cov hlau ua rau muaj ib txheej kev nyuaj siab sib npaug thiab me me. Cov txheej no muab ntau yam txiaj ntsig:
- Kev Tiv Thaiv Kev Qaug Zog Zoo Dua: Nws txhim kho lub zog qaug zog ntawm cov khoom siv hlau, tiv taus qhov pib thiab kev nthuav dav ntawm cov kab nrib pleb.
- Txo Kev Pheej Hmoo ntawm Kev Nyuaj Siab: Cov txheej txheem kev nyuaj siab compressive txo qhov tshwm sim ntawm kev nyuaj siab xeb.
- Kev Tiv Thaiv Kev Hnav Zoo Dua: Los ntawm kev ua kom me ntsis txias ua haujlwm tawv ntawm qhov chaw, nws ua rau kom muaj kev tiv thaiv kev hnav ntawm cov khoom.
4. Qhov Chaw Tiav
Vim lawv cov duab kheej kheej thiab cov yam ntxwv cuam tshuam, cov hlaws iav tsim cov nplaim uas sib xws, du, thiab tsis muaj khawb ntse, feem ntau hu ua "satin finish". Qhov tiav no muab cov khoom siv zoo tagnrho rau kev txau, txheej, lossis electroplating tom qab, kom ntseeg tau tias muaj zog nplaum.
Ntawm qhov tod tes, cov khoom siv txhuam uas muaj kaum sab xis ua rau muaj qhov chaw ntxhib nrog cov ncov thiab cov hav. Txawm hais tias qhov no kuj tseem tuaj yeem ua rau muaj kev sib txuas ntxiv rau qee qhov, nws siv cov khoom siv txheej ntau dua thiab ua rau qhov chaw tsis zoo nkauj.
Vim yog cov txiaj ntsig no, cov hlaws iav feem ntau siv rau hauv cov ntawv thov uas qhov kev ncaj ncees ntawm lub substrate yog qhov tseem ceeb tshaj plaws, xws li kev ua cov khoom precision, pwm, cov khoom aerospace, cov khoom stainless hlau, thiab cov txhuas alloy die-castings. Lawv sawv cev rau qhov kev xaiv zoo tshaj plaws rau kev ua tiav qhov sib npaug ntawm kev ntxuav qhov chaw zoo thiab kev tiv thaiv substrate.
