Cov yam ntxwv ntawm cov iav hlaws dai
Cov iav hlaws dai yog cov iav iav kheej kheej nrog txoj kab uas hla me me. Lawv tau ua los ntawm cov hmoov iav uas muaj silicon, sodium thiab calcium thiab raug rho tawm ntawm qhov kub. Vim tias nws qhov siab puag ncig, ua tau zoo, muaj zog tiv taus thiab rov xav dua, nws tau siv dav hauv thaj teb ntawm cov yas roj hmab, hnav hauv pem teb-tiv taus, tua peening, txheej txheej cuam tshuam thiab lwm yam.

Daim ntawv thov ntawm cov iav hlaws dai
Reflective iav hlaws rau txoj kev feem ntau yog siv hauv qhov kub thiab txias-yaj zoo tib yam cim kev ua haujlwm. Lawv tau txau rau ntawm daim npav xim. Ib qho yog siv ua cov khoom siv ua ntej kom ntseeg tau lub sijhawm ntev ntawm kev kos npe hauv qhov kev pab cuam lub neej, thiab lwm qhov raug faib rau saum npoo thaum cim kev tsim kho kom ua tiav cov txiaj ntsig zoo.
Kev xaiv pom zoo: cov hlaws zoo feem ntau siv rau ob kab ntawm cov kab qub, nrog rau qhov ua tau zoo; cov hlaws me me feem ntau yog siv rau txoj kev cim tshiab, nrog cov txiaj ntsig zoo tshaj plaws; cov hlaws ci siab feem ntau yog siv rau Kev cim npav, nrog kev cuam tshuam zoo heev.
