Isikhokelo esibalulekileyo seTyeyiphu yoku Masking okususwayo kwizicelo zokugqokelela kweshishini

Itheyiphu yokususwa okususwayo sisixhobo esibalulekileyo kwihlabathi lokugquma kwemizi-mveliso kunye nezicelo zokupeyinta. Ngokungafaniyo neebhayiphu zemveli, Itheyiphu yemaski esuswayo yenzelwe ngokunamathela okhethekileyo evumela ukusetyenziswa okulula kunye nokususwa ngaphandle kokushiya intsalela okanye umonakalo. umphezulu ongaphantsi. Olu phawu luncedo ngokukodwa kwiingcali ezifuna ukuchaneka nokucocwa
