Nzira yekutonga sei chokwadi chemaski yakanyunguduka jira?

   Meltblownmachira anonyanya kugadzirwa polypropylene. Kune akawanda voids, chimiro chine fluffy, uye kugona kurwisa wrinkles kwakanaka. Ane yakanaka filterability. Goodshielding, thermal insulation uye kunyudzwa kwemafuta.

Masks maviri-layer akaderera zvakanyanya. Masks ekurapwa anofanirwa kunge aine mitsara mitatu. Mativi ese ari maviri emasiki ekurapa anowanzo spunbond, uye yepakati imucheka wakanyunguduka. Mucheka wakanaka meltblown unorema zvakakwana. Inotaridzika chena pane kujeka. Inotaridzika kunge bepa. Iyo jira rakanyunguduka rakatetepa, rinotowedzera kudzivirira. Iyo yakanyunguduka inoputika layer inonyungudika kana yasangana nemoto uye haizotsva. Iyo melt blown layer ine electrostatic adsorption athari. Unogona kushandisa izvi kusiyanisa pakati pechokwadi nenhema.
