7. Ukuhlolwa kwezihombiso zeebrashi zamazinyo zaBantwana

1. ImbonakaloIukuhlolwa

- Uvavanyo lwe-Decolorization: sebenzisa umqhaphu ofunxayo ofakwe ngokupheleleyo nge-65% ye-ethanol ukosula intloko yebhrashi yamazinyo, umqheba, iibristles kunye nezihombiso kangangezihlandlo ezili-100, kwaye ujonge ngokubonakalayo ukuba kukho umbala kumqhaphu ofunxayo.

- Jonga ngokubonakalayo ukuba ingaba zonke iindawo kunye nezihombiso zebrashi yamazinyo zicocekile kwaye azinabumdaka, kwaye ugwebe ukuba kukho naliphi na ivumba ngokuvumba.

- Jonga ngokubonakalayo ukuba ngaba imveliso ipakishwe, ingaba ukupakishwa kuqhekekile, kwaye ukuba ngaphakathi nangaphandle kwepakethe kucocekile kwaye kucocekile, ngaphandle kokungcola.

- Ukuhlolwa kwepakethe yemveliso ethengiswayo iya kuba nesiqinisekiso kunye ne-toothbrush bristles engachukunyiswanga ngqo ngesandla.

2. UkhuselekoRizixhobo kunyeIukuhlolwa

- Intloko yebhrashi yamazinyo, umqheba kunye nezihombiso ziya kuhlolwa ngokubonakalayo kwi-300 mm kude nemveliso phantsi kokukhanya kwendalo okanye ukukhanya kwe-40W ngendlela yokuziva ngesandla.Ukubonakala kwentloko yebhrashi yamazinyo, umqheba kunye nemihlobiso iya kuba lula (ngaphandle kwenkqubo ekhethekileyo), ngaphandle kwemiphetho ebukhali kunye ne-burrs, kwaye ukumila kwayo akuyi kubangela ingozi kumzimba womntu.

- Jonga ukuba intloko yebhrashi yamazinyo iyaqhawuka na ngokuhlolwa okubonakalayo kunye nokuziva ngesandla.Intloko yebrashi yamazinyo ayinakususwa.

- Izinto ezinobungozi: umxholo we-antimony enyibilikayo, i-arsenic, i-barium, i-cadmium, i-chromium, i-load, i-mercury, i-selenium okanye nayiphi na ikhompawundi enyibilikayo eyenziwe zezi zinto kwimveliso ayiyi kudlula ixabiso kwiThebhile 1.

3. Ukuhlolwa kweSukucaciswa kunyeSize

Inkcazo kunye nobukhulu bulinganiswa ngokulandelelana kunye ne-vernier caliper enexabiso elincinci lokuhlula i-0.02 mm, 0.01 mm ngaphandle kwe-micrometer ye-diameter kunye ne-0.5 mm yerula.Ukucaciswa kunye nobungakanani (jonga i-Fig. 1) iya kuhlangabezana neemfuno kwiThebhile 2.

4. Ukuhlolwa kweBristleSubude

- Jonga ngokubonakalayo ukuba ulwahlulo lwamandla e-bristle kunye nedayimitha ye-monofilament ibonakalisiwe kwi-package yemveliso.

Ulwahlulo lwamandla ebristle luyakwamkela ibristle ethambileyo, oko kukuthi, amandla okugoba ebristle yebrashi yamazinyo aya kuba ngaphantsi kwe-6N okanye idiameter yegama (ϕ) ye-monofilament iya kuba ngaphantsi okanye ilingane ne-0.18mm.

5. Ukuhlolwa kwePhysicalPukusebenza

Ukusebenza ngokomzimba kuya kuhlangabezana neemfuno ezikwiThebhile 3.

6. UkumangalelaIukuhlolwa

- I-angle ebukhali iya kususwa kwaye akukho burrs iya kufumaneka kwi-contour ephezulu ye-monofilament ye-toothbrush bristles.I-contour ephezulu ye-monofilament efanelekayo kunye nengafanelekanga njengoko kuboniswe kwi-a) kunye ne-b) ye-Fig.

- Thatha iinyanda ezintathu kumphezulu webristle webrashi yamazinyo emcaba, susa imiqulu emithathu yeebristles, uzincamathele ephepheni, kwaye uzijonge ngemakroskopu amaxesha angaphezu kwama-30.Umlinganiselo ofanelekileyo we-contour ephezulu ye-monofilament ye-flat bristle toothbrush iya kuba nkulu okanye ilingane ne-70%;

Thatha inyanda enye kwibhrashi yamazinyo ephezulu, ephakathi kunye nesezantsi, susa ezo zinyanda zintathu zeebristles, uzincamathele ephepheni, kwaye uziqwalasele ngemakroskopu amaxesha angaphezu kwama-30.Umyinge ofanelekileyo we-contour ephezulu ye-monofilament ye-brush yamazinyo ekhethekileyo enemilo ekhethekileyo iya kuba nkulu okanye ilingane ne-50%.

7. Ukuhlolwa kweOkanyeniintlungu

- Uluhlu lobudala olusebenzayo luya kuboniswa kwipakethe yentengiso yeebrashi zamazinyo zomntwana.

- Ukukhawuleza kwimihombiso engasuswayo yeebrashi zamazinyo zomntwana iya kuba nkulu okanye ilingane ne-70N.

- Izihombiso ezinokususwa zeebrashi zamazinyo zomntwana ziya kuhlangabezana neemfuno.

8. Ukuhlolwa kweAimbonakaloQimeko

Jonga ngokubonakalayo imveliso kumgama we-300 mm phantsi kokukhanya kwendalo okanye ukukhanya kwe-40 W.Kwiziphene zamaqamza kumqheba webrashi yamazinyo, imephu yothuli eqhelekileyo iya kusetyenziswa ukuhlola uthelekiso.Umgangatho wenkangeleko uya kuhambelana nemigaqo ekwiThebhile 4.
