Khoom yam ntxwv
Txheem, siab- cov bristles zoo yog ua los ntawm nylon filaments; Cov khoom lag luam hwm feem ntau siv DuPont nylon, thaum qee cov qauv tshiab suav nrog cov ntaub ntawv xws li cov kab mob tua kab mob los yog xyoob fibers. Cov plaub hau tsiaj ntuj yuav tsum raug zam, vim nws yog cov kab mob loj hlob thiab ua tsis tau raws li cov qauv kev nyiam huv.
Yam ntxwv Dimensional
Rau cov neeg laus cov mos mos- txhuam txhuam, txoj kab uas hla ntawm monofilament yog tsawg dua lossis sib npaug li 0.18 hli, nrog ultra- txhuam txhuam zoo li ntawm 0.12 txog 0.15 hli; Cov menyuam txhuam hniav txhuam hniav yuav tsum tsis pub tshaj 0.18 hli hauv txoj kab uas hla, thaum cov qauv tsim rau cov me nyuam mos thiab cov me nyuam me yuav tsum muaj txoj kab uas hla tsawg dua lossis sib npaug li 0.15 hli.
Hais txog lub bristle array, tag nrho ntev (bristle nto ntev) yog feem ntau 2.5-3 cm rau cov neeg laus thiab tsis ntau tshaj 2.9 cm rau cov me nyuam; lub bristle nto dav tsis pub tshaj 1.4 cm rau cov neeg laus thiab 1.1 cm rau cov me nyuam, feem ntau muaj 3-4 kab ntawm bristles.
Cov yam ntxwv ua haujlwm
Cov bristles yuav tsum muaj qhov tsim nyog elasticity, tso cai rau lawv rov qab sai sai tom qab compression yam tsis muaj matting; Qhov no ua kom lawv tuaj yeem nkag mus rau hauv cov gingival sulcus kom tshem tawm cov quav hniav yam tsis muaj kev sib tsoo lossis poob kev ua haujlwm ntawm kev ua haujlwm hauv siab. High- cov bristles zoo zoo muaj lub zog dabtsi yog khoov tsawg dua lossis sib npaug li 0.25 N thiab ua rau tsis muaj qhov cuam tshuam tseem ceeb thaum nias rau sab nraub qaum.
