Ndezvipi zvinodiwa pakushandisaMasiki anoraswa?Jinhaocheng inyanzvi yekugadzira masiki anoraswa.

Masiki anoraswa anogadzirwa nezvikamu zvitatu kana kupfuura zvemagiramu makumi maviri nemasere ejira risina kurukwa; Bhiriji remhino rakagadzirwa nepurasitiki isingakuvadzi nharaunda, isina simbi, uye inofema uye inonyaradza, inonyanya kukodzera mafekitori emagetsi uye kushandiswa kwezuva nezuva. Masiki anoraswa (masiki ekuvhiya ekurapa) anogona kudzivirira kubva kuzvirwere zvekufema kusvika pamwero wakati, asi kwete kubva kuhutsi. Zvakakosha kuziva kuti unofanirwa kusarudza masiki akanyorwa zvakajeka kuti "masiki ekuvhiya ekushandisa kwekurapa" papakeji.

Kune mhando dzakawanda dzemasiki dzinoraswa, dzinofanira kusarudzwa zvichienderana nezvinodiwa zvebasa zvakasiyana nemamiriro ekushanda.

Kana tunhu twacho tuine chepfu yakawanda, tunokonzera kenza uye tune mwaranzi, chinhu chinosefa chine simba guru rekusefa chinofanira kusarudzwa.

Kana zvidimbu zvacho zvine mafuta, iva nechokwadi chekusarudza chinhu chakakodzera chekusefa.

Kana zvinhu zviri mu granular fiber, zvakaita se slag wool, asbestos, glass fiber, nezvimwewo, magust masks haafanirwe kusukwa nemvura, uye magust masks ane microfiber yakabatana nechisimbiso chechiso anogona kukonzera kutsamwa kwechiso uye haazokodzeri kushandiswa.
