Inxalenye yokuhluza imaski yesiqingatha (8228V-2 FFP2)

Ziziphi iingenelo zeemaski ezineevalvu zokuphefumla?
Ivalve yokuphefumla yemaski ifanelekile kwindawo eshushu noko.Kuya kuphefumula ngakumbi xa kuphuma, kwaye i-valve yokuphefumla i-valve iya kuvala ngokuzenzekelayo, engayi kuchaphazela umphumo wokusetyenziswa nonke.

Xa kuthelekiswa neemaski zobuso eziqhelekileyo, iimaski ezinevalvu zokuphefumla zifaneleke ngakumbi kwimo engqongileyo yokusetyenziswa rhabaxa kwaye zikhuthaza ngakumbi ukuphefumla kwabantu.Kwindawo yokusebenza efumileyo neshushu enomoya omdaka okanye inani elikhulu labasebenzi, ukusebenzisa imaski enevalve yokuphefumla kunokukunceda uzive ukhululekile xa uphefumla.

Umgaqo womsebenzi wevalve yokuphefumla kukuba uxinzelelo olulungileyo lwegesi ekhutshiweyo luvuthela ipleyiti yevalve xa ikhupha umoya, ukuze kupheliswe ngokukhawuleza igesi yenkunkuma emzimbeni kunye nokunciphisa ukuvaleka kunye nokutshisa xa usebenzisa imaski.Uxinzelelo olubi xa uphefumla luya kuvala ngokuzenzekelayo ivalve ukuphepha ukuphefumla ungcoliseko olusuka kwindawo yangaphandle.

Imaski yobuso kunye nomqhaphu we-acupuncture
Umqhaphu we-acupuncture ukwabizwa ngokuba yinaliti ye-punch eyenza umqhaphu kumzi-mveliso wemaski wothuli olulahlwayo.Inaliti ehlatyiweyo yomqhaphu yemaski luhlobo lwemathiriyeli yemaski eyenziwe ngenkqubo yokulifuna.Ikwabizwa ngokuba yimaski yobungqina bothuli emva kokudityaniswa nokusetyenzwa kwemaski.Inaliti ehlatyiweyo yomqhaphu yemaski luhlobo lwemathiriyeli yokucoca, eyenziwe ngefiber yepolyester ngenkqubo yokuhlatywa ngenaliti.Kwinkqubo yokudlula kule sixhobo sokucoca, uthuli lokuphefumla luya kubhengezwa phakathi kwemicu, edlala indima ekuthinteleni uthuli.

Iimaski zomqhaphu ezifakwe inaliti zifanelekile kwimigodi, ukwakhiwa, isiseko, ukugawula kunye noshishino lwamayeza, ezolimo kunye nokulima, amahlathi kunye nokugcinwa kwezilwanyana, ubunjineli bomzila ongaphantsi komhlaba, ukusebenza kwe-aluminium, izixhobo zombane kunye nombane, izixhobo kunye nokuveliswa kwezixhobo, ishishini lokulungisa ukutya, isityalo sesamente, iplanti yempahla, isixhobo kunye neplanti yehardware, sheet metal grinding, polishing, cut, disassembly engineering, crushing operation.Ziyakwazi ukuthintela ngempumelelo iintsimbi ezingezizo i-ferrous, isinyithi esinzima kunye nezinye izinto ezingcolileyo eziyingozi, kunye ne-block glass fiber Asbestos kunye nezinye izinto eziyingozi.

Umahluko woxinzelelo yenye yeendlela zokuvavanya imaski.

Indlela yokuvavanya - Umahluko woxinzelelo
Umahluko woxinzelelo, okanye ukwehla koxinzelelo, kubonisa indlela ekulula ngayo ukuphefumla ngesixhobo sokucoca.Umahluko woxinzelelo ngokuqhelekileyo ugqitywe ngokulinganisa uxinzelelo lomoya kumacala omabini wesixhobo sokucoca ngelixa umoya uhamba ngesantya esaziwayo ngesixhobo sokucoca.Umahluko woxinzelelo ngumahluko phakathi koxinzelelo lomoya ezimbini.Umahluko woxinzelelo oluphantsi uthetha ukuba umoya udlula ngokulula kwizinto zokucoca, oko kwenza kube lula ukuphefumla.Kuseto olunikiweyo lovavanyo, ukucutha isantya somoya kuya kunciphisa umahluko woxinzelelo kwaye ukwandisa ubukhulu besixhobo sokucoca kuya kwandisa umahluko woxinzelelo.

Ukwahlukana koxinzelelo ngokuqhelekileyo kuchazwe kwiiyunithi zepascal (Pa) (1.0 Pa = 0.102 mmH2O).Eminye imigangatho yokwahluka koxinzelelo kwiimaski zotyando isebenzisa iyunithi ye-Pa/cm2, engenantsingiselo ngokwasemzimbeni.Olu vavanyo, nangona kunjalo, luchaza indawo engaphezulu yesixhobo semaski esivavanyiweyo, ke amaxabiso aphindwe kabini kwindawo evavanyiweyo ukufumana iyunithi enentsingiselo ngokwasemzimbeni, iPa.

EN 149:2001
EYurophu, iziphefumlo zokucoca ubuso kufuneka zibe neempawu eziboniswe ngumgangatho we-EN 149: 2001 (+ A1: 2009), eyalela ukuba ezi maski, phakathi kwezinye izinto, kufuneka zibe neempawu ezithile zokuphefumla, ukuvuza kwangaphakathi, ukutsha, ukuqokelela kweCO2 , njl. Umgangatho we-EN 149:2001 (+ A1: 2009) ufuna ukuba amandla okuhluza imaski avavanywe zombini nge-aerosol yamasuntswana e-NaCl anobubanzi bosasazo lwe-median phakathi kwe-0.06 kunye ne-0.10 μm kunye ne-aerosol yamasuntswana eparafini. i-oyile enobubanzi obuphakathi kokusasazwa phakathi kwe-0.29 kunye ne-0.45 μm;akukho vavanyo lwe-bacterial filtration eceliweyo.Ngokusekelwe kumthamo wabo wokucoca, i-facepiece respirators yokucoca ihlelwa kuhlobo lwe-FFP1 (umthamo wokucoca i-aerosol ye-NaCl kunye ne-oyile yeparafini ilingana ne-80%), i-FFP2 (umthamo wokucoca i-NaCl i-aerosol kunye ne-oyile yeparafini ilingana ne-94%) kunye ne-FFP3 (umthamo wokucoca ye-aerosol ye-NaCl kunye ne-oyile yeparafini ilingana ne-99%).
