Ukuba icebo lokucoca isigqumathelo igesi: Ukuhlelwa, isikhundla, ukumakisha, ixesha lokugcina. device imaski

Kwiimeko ezininzi likaxakeka zifuna iimaski, njengoko kuvumela ukucoca umoya ingcolisekile. Yenza lo msebenzi lokucoca ulwelo. Ekubeni ngokuhamba kwexesha akakwazi ukucoca umgangatho womoya, kufuneka zitshintshwe. Zizixhobo kunceda kwiimeko ezingxamisekileyo.

Isigqumathelo lokucoca has a high Polymer-metal okanye ifomu iqokobhe zezindlu edityanisiweyo. Izixhobo iqulathe filter yamasuntswana kunye nesigxina (core izifunxi). Isiseko na umbandela lokuqala multi-candelo kunye sikhokelo kwimicu neselulosi kunye necandelo nocococ, equka Imicu asbestos, imicu zeglasi kunye zokwenziwa.

isixhobo imaski ivumela ukuba balwazi ukuba lusebenza njani. Kukho kagesi izinto filter eyenzelwe ukuba zifake amasuntswana usebenzisa electrostatics. zokuhlanjululwa umoya osuka amasuntswana nothuli ukuba ubukhulu iseli kwesisefo, yenzelwa zoomatshini.

carbon luvuliwe ezisetyenziswa izixhobo kunye lokufaka Wabonisa izifunxi. Le ukuze ukuphucula iipropati lokuhluza. Le ntlawulo ibizwa umaleko absorber, eliquka luvuliwe carbon additive. Ngoncedo lwabo, iphucula amacandelo isimemezelo. kwezithako ezinjalo ziquka oxides intsimbi kunye neetyuwa. Loo isixhobo ivumela tifihla isihluzi ubunjani emoyeni.

Ukubunjwa imaski igesi

Icebo yokhuseleko iquka iindawo ezininzi ezibalulekileyo, ekukhuseleni ngokuchasene ezingcolisa zabantu. Inani amacandelo afunekayo ziquka:

• phambi irabha inxenye: kuquka kokuxhuma umbhobho nesivalo bhokisi;
• ibhokisi valve;
• ohlanganisa tube;
• yokuhluza-okubamba ibhokisi;
• protivogaznaya bag.

Zonke iindawo imaski kuyimfuneko kuba filter umoya inikwa kunye nabo. Ukuba ezinye iindawo iziphene zibonakale, kuyimfuneko ukuba indawo kubo.

iiklasi Security

Xa uhlobo 'ngesihlungulo "isuntswana lokucoca ke kwiiklasi ezininzi yokuzikhusela:

• ukulibala uthuli ngoboya;
• akavumeli uthuli, umsi, inkungu;
• It likhusela ngokuchaseneyo kakuhle iinkungu, inkungu, umsi, iintsholongwane kunye neentsholongwane.

Yeyiphi ukuba ukhethe i filter kuba imaski kuxhomekeke kudidi yonxunguphalo. Kuyo nayiphi na imeko, isixhobo kuya kusikhusela kwimiphumo umoya ingcolisekile. Kukho indlela ngeenjongo ezithile, umz, ukuba nge- imaski igesi ammonia.

uphawu

canisters lokucoca ulwelo imaski irhasi iphawulwe ngolu hlobo lulandelayo:

• A (brown): esikhusela ipetroli, iparafini, acetone, benzene, toluene.
• I (esimthubi): musa ungaphoswa chlorine, sulphur dioxide, hydrogen chloride, hydrogen sulphide, phosgene.
• T (yellow-black): esikhusela mercury kunye nezinto eziphilayo.
• KD (grey) umkhumbula ammonia, emanzini.
• E (abamnyama) likhusela ngokuchaseneyo ukungena hydrides of iarseniki, Phosphate.
• M (ebomvu) umkhumbula carbon monoxide kunye imveliso zomgquba, ammonia, iigesi acid.
• WO (white) ukhusela umntu carbon monoxide.
• BKF: ezikhusela neegesi acid, umphunga eziphilayo, olutshizwa, hydrides of iarseniki, phosphorus.

Ezi iibhokisi ininzi kakhulu, aphakathi kunye encinane, nto leyo ebonisa ubude zokuzikhusela umoya ingcolisekile. Ukuba babe filter yamasuntswana, ixesha lo msebenzi lifinyele. Oku kungabonwa bubukho wachuba iindawo ezimhlophe nkqo, kwaye iibhokisi ezincinane - umbala omhlophe ye emazantsi. Boxes A, B, CD, D, E ngaphandle lokucoca yamasuntswana zibonakaliswe yi Inani u-3 Ngoko ke, iimpawu zabo angamelwa njengoko - A3B3Reactor2. Kulo mzekelo, icebo lokucoca ukuba isigqumathelo igesi 3 uye ukhuseleko uhlobo udidi A. isiqinisekiso nkcukacha zibe kwiminyaka 3-5.

Isikhundla kwezixhobo ezintsha

Ucalulo okucoca for iimaski igesi iintlobo ezintsha ukuze imibala kunye neeleta zokumakisha ezahlukeneyo. Le mithetho yenziwe ingqinelane ne-EU. Kukho le notation zilandelayo:

• A (brown) likhusela ngokuchaseneyo igesi, umphunga ngaphezu degrees 65 organic.
• B (grey): likhusela evela neegesi ezingaphiliyo, ngaphandle kuphela carbon.
• CO (purple) inika ukhuseleko ngokuchasene carbon monoxide.
• E (esimthubi): musa akakuphosi iigesi asidi, abe ngumphunga acid.
• K (green): umntu ukhuselwe ukusuka ammonia kunye ngomdla kusitsha.
• P (white): likhusela yibhaktheriya, iintsholongwane.
• HG (ebomvu): kuyimfuneko ukususa nesigidi kunye nemixube ezililize.
• Kugawulwa (brown): Musa ukushiya izinto eziphilayo.
• Sx (Violet) okucoca ubuthi eziyityhefu.
• Reaktor (orange): likhusela ngokuchaseneyo izinto ezineeathom ezilinganayo iodine.

Modern imaski filter efunekayo ukuze kukhuselwe umgangatho abantu izinto eziyingozi emoyeni.

Tips for Ukukhetha

izixhobo kufuneka abe kwigumbi apho umoya ngaphantsi kwe-18% ioksijini, kunye ezingcolisa afumaneka yoxinaniso eliphezulu. ibhokisi lokucoca kufuneka zikhethwe ukwenzela ukuba ezifanelekileyo emoyeni.

Ukuba kufuneka ukubamba abantu ngenxa umsi, apho nakolu carbon monoxide, oluyimfuneko CO 2 zokuphawula kwibakala emhlophe. In mixed Ngababini kungcoliseko ngeegesi organic kunye acid kufuneka ukhethe ibhokisi BKF. Kunye respirators gassed isetyenziswe filter igesi.

Xa kufuneka replacement?

Ulwazi malunga ixesha amanyathelo izakhelo ziya kusebenza umsebenzi njengesingqiniso iimaski lokucoca ulwelo. amaxesha Ukugcinwa zinokuba nomahluko, konke oko kuxhomekeke imodeli. Kukho iindlela eziliqela lokuhlahla evumela ukuseka imfuneko indawo yokuhluza. Le nkqubo iyafuneka xa phantsi ngesebe buqapheleke igesi enetyhefu. Indlela kuyingozi kuba ziviwa iigesi yoxinaniso phezulu ngokucacileyo.

indawo yokuhluza iyafuneka xa utshintsha ubunzima kwefowuni. Olu khetho efanelekileyo yeebhokisi CO kuthinjwe. Basebenza kwi ukufuma ephantsi kwi phezulu akusebenzi. Ngenxa ukufunxeka ukufuma kunye nezixhobo ndibopha ubunzima ngakumbi.

Utshintsho kufuneka emva kwexesha ezinye ukusetyenziswa. Option ilungele ukuba iimaski brand G. Ukuba iyunithi yasetyenziswa iiyure ezimalunga ne-100, ibhokisi kufuneka itshintshwe. imaski ngalinye lingaba ubomi babo ukonakala. Kubalulekile ukuba ukuthobela nabo, njengoko kuchaphazela ukhuseleko lomntu.

Faka icebo lokucoca ulwelo elitsha ingaqhuba iye phandle kwishedyuli. Kulo mzekelo, ibhokisi kufuneka itshintshwe rhoqo ukuba amacandelo eziyingozi emoyeni eninzi. Iinkqubo ziqhutywa emva izifundo elebhu. Emva koko ukuhluza umhla wokuphelelwa ebekwe yi nokuhlola. Ukwenza umzekelo zekhompyutha kwexesha yomsebenzi okucoca likuvumela ukuba ukuchaza izinto ezimbi, kubandakanywa lobushushu nokufuma. ixesha replacement kuxhomekeke iziqalelo - woluvo. ufakelo ngexesha lokucoca ikuvumela ukuba usebenzise ifowuni ngaphandle umonakalo kwimpilo.
