Imiba yobuchwephesha ye-KN95|KENJOY

Ngoku kubomi bethu bemihla ngemihla, kufuneka sinxibe imaski naphi na apho siya khona, kodwa mhlawumbi asazi kakhulu ngayoIimaski ze-KN95.Namhlanje,ababoneleli bemaski sazise kulwazi olusisiseko lweemaski ze-KN95.

Umthombo osemgangathweni

I-KN95 yimaski esemgangathweni yaseTshayina, luhlobo lwemaski enobuchule bokucoca into ethile kwilizwe lethu.Iimaski ze-KN95 kunye neemaski ze-N95 ziyafana ngokwemigaqo yokusebenza kakuhle kokucoca.

I-KN95 sisimaski esiqhelekileyo saseTshayina, esivela kumgangatho wesizwe waseTshayina we-GB 2626-2019 "Isixhobo sokuphefumla esiKhuselekileyo soKhuseleko lwesixhobo sokuphefumla esiAnti-particulate respirator".Lo mgangatho ngumgangatho onyanzelekileyo wesizwe e-China, obekwe phambili nguRhulumente woLawulo loKhuseleko lomsebenzi kunye phantsi kolawulo lweKomiti yeSizwe yezobuGcisa yoMgangatho wezixhobo zoKhuseleko zomntu ngamnye (SAC / TC 112).

Inqanaba lobuchwephesha

Ukusuka kwindawo yokujonga umda wesicelo, lo mgangatho usebenza kwizixhobo eziqhelekileyo zokuzikhusela kunye nokucoca ukuphefumla ukukhusela zonke iintlobo zeemaski, ezinye iindawo ezikhethekileyo (ezinje ngemekobume ye-anoxic, ukusebenza phantsi kwamanzi, njl. ) ayisebenzi.

Ngokusuka kwinkcazo yento ethile, lo mgangatho uchaza iindlela ezahlukeneyo ze-particle, kubandakanywa uthuli, umsi, inkungu kunye ne-microorganisms, kodwa ayichazi ubungakanani bento encinci.

Ngokomgangatho wecebo lokucoca, linokwahlulwa libe ziindidi ezimbini: icebo lokucoca umba ongekho-oyile KN kunye nesihluzo esinamafutha kunye nenkcaza engenanto i KP, kwaye usebenzise oku njengophawu, olufana nesandla se-N kunye ne-R _. I-P echazwe kwizikhokelo zokutolika kwe-CFR 42-84-1995.

Imibandela efuna ingqalelo

Kuyaphawuleka ukuba i-GB 2626-2006 "Isixhobo soKhuseleko sokuphefumla esiziphefumlelayo isihluzi se-Anti-particulate respirator" sele siza kungasebenzi, sithathela indawo inguqulelo yayo entsha ye-GB 2626-2019 "Isixhobo soKhuseleko sokuPhumla self-priming filter Anti-particulate respirator", ekhutshwe kuluntu luphela nguLawulo lukaRhulumente loLawulo lweMarike kunye noLawulo ngoDisemba 31, 2019, kwaye iya kuphunyezwa ngokusesikweni ngoJulayi 1, 2020. Umgangatho omtsha ubekwe phambili kwaye ubekwe phambili liSebe loLawulo oluNgxamisekileyo.

Okwangoku, isicatshulwa somgangatho omtsha siye sapapashwa kwaye senziwe safumaneka kuluntu lonke ngaphandle kwentlawulo njengomgangatho osinyanzelo.Umgangatho omtsha uzalisekisa amagama asixhenxe afana ne "aerodynamic particle size" kwaye iguqule ezinye iimfuno zobugcisa kunye neendlela zokuvavanya, kodwa ayilulungisi ulwahlulo, ukumakisha kunye nokusebenza kakuhle kokucoca okudweliswe kweli phepha.

I-N95 ngumgangatho waseMelika

Imaski e-N95 yenye yeentlobo ezili-9 zeemaski ezikhuselweyo ezingqinisiswe yi-NIOSH (Iziko leSizwe loKhuseleko eMsebenzini kunye neMpilo, iZiko leSizwe loKhuseleko eMsebenzini kunye neMpilo).I-N95 ayilona igama elithile lemveliso, nje ukuba idibana nomgangatho we-N95 kunye nemveliso egqithise ukuphononongwa kwe-NIOSH ingabizwa ngokuba yi-mask ye-N95, enokucoca amaqhekeza nge-aerodynamic diameter ye-0.075 μ m ± 0.020 μ m nge ukuhluza okungaphezulu kwe-95%.

Oku kungasentla kukwaziswa kobugcisa be-KN95.Kufuneka sazi ngakumbi malunga neemaski zeFFP2.Nceda uzive ukhululekile ukuqhagamshelana nathiumzimveliso wemaskiukufumana iingcebiso.
