- Saib xyuas seb txhua qhov chaw thiab cov khoom siv ntawm cov txhuam hniav puas huv thiab tsis muaj av, thiab txiav txim seb puas muaj ntxhiab tsw los ntawm olfaction.

- Saib xyuas seb cov khoom puas tau ntim, seb lub ntim puas tawg, thiab seb lub ntim sab hauv thiab sab nraud puas huv thiab huv, tsis muaj av.

- Kev tshuaj xyuas cov khoom ntim rau kev muag khoom yuav tsum tsim nyog nrog cov txhuam hniav bristles tsis raug kov ncaj qha los ntawm tes.

2. Kev nyab xeebRcov khoom siv thiabIkev soj ntsuam

- Cov txhuam hniav lub taub hau, kov thiab cov khoom zoo nkauj yuav tsum tau kuaj pom qhov deb ntawm 300 hli ntawm cov khoom nyob rau hauv lub teeb ntuj lossis 40W lub teeb los ntawm txhais tes hnov.Cov tsos ntawm txhuam hniav lub taub hau, kov thiab ornaments yuav tsum du (tshwj tsis yog rau cov txheej txheem tshwj xeeb), tsis muaj cov npoo ntse thiab burrs, thiab cov duab ntawm nws yuav tsum tsis txhob ua rau tib neeg lub cev.

- Xyuas seb lub taub hau txhuam hniav puas tuaj yeem tshem tau los ntawm kev tshuaj xyuas qhov muag thiab txhais tes.Lub taub hau txhuam hniav yuav tsum tsis txhob muab tshem tawm.

- Cov ntsiab lus txaus ntshai: cov ntsiab lus ntawm soluble antimony, arsenic, barium, cadmium, chromium, lead, mercury, selenium los yog ib qho soluble compound uas muaj cov ntsiab lus hauv cov khoom yuav tsum tsis pub tshaj tus nqi hauv Table 1.

Table 1

3. Kev tshuaj xyuas rauSpecification thiabSize

Cov kev qhia tshwj xeeb thiab qhov loj me yog ntsuas raws li cov vernier caliper nrog qhov sib faib yam tsawg kawg nkaus ntawm 0.02 hli, 0.01 hli sab nraud txoj kab uas hla micrometer thiab 0.5 hli kav.Qhov Specification thiab Loj (saib daim duab 1) yuav tsum ua kom tau raws li qhov yuav tsum tau muaj hauv Table 2.

4. Kev tshuaj xyuas rauBristleSzog

- Saib xyuas seb puas muaj kev faib tawm lub zog bristle thiab nominal txoj kab uas hla ntawm monofilament tau qhia rau ntawm cov khoom ntim.

Kev faib tawm lub zog bristle yuav tsum tau txais cov txhuam mos, piv txwv li, lub zog khoov ntawm tus txhuam hniav bristle yuav tsum tsawg dua 6N lossis nominal txoj kab uas hla (ϕ) ntawm cov monofilament yuav tsum tsawg dua lossis sib npaug li 0.18mm.

5. Kev tshuaj xyuas ntawmPhysicalPkev ua haujlwm

Kev ua tau zoo ntawm lub cev yuav tsum ua tau raws li qhov yuav tsum tau ua hauv Table 3.

Table 3

6. SuedingIkev soj ntsuam

- Lub kaum ntse ntse yuav tsum raug tshem tawm thiab tsis muaj burrs yuav tsum pom nyob rau sab saum toj contour ntawm monofilament ntawm cov txhuam hniav txhuam.Tsim nyog thiab tsis tsim nyog sab saum toj contour ntawm lub monofilament yog raws li qhia nyob rau hauv a) thiab b) ntawm daim duab 2.

- Siv peb lub pob los ntawm lub ntsej muag txhuam hniav ntawm cov txhuam hniav tiaj tus, tshem tawm peb lub pob bristles, lo rau ntawm daim ntawv, thiab saib xyuas nrog lub tshuab tsom iav ntau dua 30 zaug.Qhov tsim nyog tus nqi ntawm sab saum toj contour ntawm lub monofilament ntawm lub tiaj tus txhuam hniav yuav tsum ntau dua los yog sib npaug rau 70%;

Siv ib pob los ntawm txhua qhov siab, nruab nrab thiab qis bristles rau cov txhuam hniav tshwj xeeb, tshem tawm peb lub pob bristles, lo rau ntawm daim ntawv, thiab saib xyuas lawv nrog lub tshuab tsom iav ntau dua 30 zaug.Qhov tsim nyog tus nqi ntawm sab saum toj contour ntawm monofilament ntawm tus txhuam hniav tshwj xeeb zoo li tus txhuam hniav yuav tsum ntau dua lossis sib npaug li 50%.
