Sharaxaadda caadiga ah ee heerka qalabka neefsashada boodhka warshadaha | JINHAOCHENG

WarshadahaMaaskarada boodhka FFP2waa nooc xirfadle ah oo maaskaro ah, kaas oo ah caqabad muhiim ah oo lagu ilaalinayo shaqaalaha ka shaqeeya macdanaha dhuxusha, warshadaha wax lagu dhalaaliyo iyo kiimikada. Sidaa darteed, maaskarada boodhka warshadaha waxay leeyihiin heerar dhammaystiran oo heer qaran ah iyo heerarka heerka ilaalinta.

Dhammaan maaskarada boodhka ah waa inay buuxiyaan heerarka aasaasiga ah ka hor inta aan loogu yeeri karin maaskarada boodhka warshadaha ee aqoonta leh. Marka xigta, raac soo saarayaasha maaskarada boodhka Jin Haocheng si aad u fahamto.

Heerka aasaasiga ah ee qalabka neefsashada boodhka warshadaha:

Maaddada maaskarada boodhka waa inay ahaataa mid aan cuncun lahayn oo aan xasaasiyad ku lahayn maqaarka, walxaha shaandheyntuna waa kuwo aan waxyeello u lahayn jidhka aadanaha. Qaab-dhismeedka maaskarada boodhka waa inuu ahaadaa mid ku habboon in la isticmaalo; Hufnaanta shaandhaynta maaskarada boodhka (heerka iska caabbinta boodhka), heerka iska caabbinta boodhka ee dhexroorka walxaha ka yar 5 micron waa inuu ka weynaadaa 90%, heerka iska caabbinta boodhka ee dhexroorka walxaha ka yar 2 micron waa inuu ka weynaadaa 70%, iwm.

Heerka loogu talagalay heerka qalabka neefsashada boodhka warshadaha:

Heerka maaskarada boodhka waxaa loo qaybiyaa maaskarada boodhka saliidda fasalka P iyo maaskarada boodhka aan saliidda ahayn fasalka N; Sida waafaqsan waxqabadka iska caabbinta boodhka iyo heerka iska caabbinta boodhka waxaa loo qaybiyaa KN90, KN95, KN100, KP90, KP95, KP100 lix qaybood. Nooca KP wuxuu ku habboon yahay boodhka saliidda leh, sida paraffin, saliidda jadeecada, iwm.

Nooca KN wuxuu ku habboon yahay ka hortagga boodhka aan saliidda lahayn, sida milixda, dhagaxa iyo wixii la mid ah. Tirada badan ee qaabka ku jirta, ayaa sii kordheysa heerka iska caabbinta boodhka, ayaa sii kordheysa qodobka badbaadada boodhka. Waqtiga wax iibsiga, maaskarada loo baahan yahay waa in la doortaa iyadoo loo eegayo heerarka kala duwan ee boodhka ee deegaanka.

GB2626-2006 sidoo kale waxay qeexaysaa isku-darka caadiga ah ee iska caabbinta neefsashada iyo iska caabbinta neef-mareenka ee maaskarada boodhka. Shaqaaluhu waa inay dareemaan raaxo iyagoo xiran maaskaro boodhka ah oo ay awoodaan inay si fudud u neefsadaan oo ay neefsadaan iyagoon dhib ku qabin neefsashada, badanaa heer ah 20 neefsasho daqiiqaddii. Isu-darka hawo-qaadashada joogtada ah ee iska caabbinta neef-mareenka iyo neef-mareenka waa 85 L/daqiiqo.

Heerku wuxuu sidoo kale dhigayaa in aqoonsiga badeecadu uu noqdo mid cad oo cad, aqoonsigana la muujiyo.

(1) Magaca iyo calaamadda ganacsiga (sida magaca "maaskarada boodhka", calaamadda ganacsiga ee "caymiska shaqada", iwm., dadka si cad u muujiya marka la eego);

(2) nooc (sida KN90, KN95, KP100, si fudud loo iibsan karo si loo ogaado kuwa maaskaro ku sameeya/ama boodhka aan saliidda ahayn, heerka iska caabbinta boodhka ayaa sarreeya;

Hirgelinta lambarka caadiga ah iyo lambarka sanadka, nooca asalka ah ee shaandhada, nooca heerka boodhka, sida 2626-2006KP90.

Ku saabsan maaskaro:

1. Farqiga u dhexeeya maaskaro: Farqiga heerka ilaalinta; B Farqiga qaabka xirashada (madaxa, dhegaha xirashada); Farqiga qaabka C (nooca laablaabashada, oo lagu daray nooca).

2. Heerka ilaalinta ee maaskarada: N95 waa heerka Mareykanka, KN90 iyo KN95 waa heerka Shiinaha, FFP2 iyo FFP3 waa heerka Yurub. Isbarbardhigga gaarka ah waa sidan soo socota: FFP3>FFP2=N95=KN95>KN90, heerka ilaalinta oo sarreeya, ayaa saameynta shaandhaynta ka sii wanaagsanaanaysa.

3. Waqtiga isticmaalka maaskarada: maaskarada dib ayaa loo isticmaali karaa, iyadoo loo eegayo deegaanka kala duwan, wasakh jabtay, waa in lagu beddelaa waqtigii loogu talagalay; Waxaa lagu taliyay walxaha saliidda ee walxaha ah, Nooca R ee isticmaalka wadarta ah waa in aan ka badnayn 8 saacadood, Nooca P ee isticmaalka wadarta ah waa in aan ka badnayn 40 saacadood.

Ku saabsan baakadaha:

Baakadaha, heerku wuxuu sidoo kale caddaynayaa: xirmada iibka ugu yar, macluumaadka soo socda waa in lagu calaamadeeyaa Shiinaha si cad oo waara, ama lagu arki karaa baakad hufan: magaca, calaamadda ganacsiga; Nooca iyo qaabka maaskarada; Lambarka heerka fulinta lambarka sanadka, lambarka shatiga badeecada; Taariikhda wax soo saarka ama tirada dufcadda ee wax soo saarka, cimriga shelf, iwm. Tani waxay kaa caawineysaa inaad ogaato haddii badeecaddu dhacday.

Waxaan nahay shirkad xirfadle ah oo soo saarta maaskaro boodhka ah, Huizhou Jinhaocheng Nonwoven Co., Ltd. Waxaan rajeyneynaa in maqaalkani uu wax yar kaa caawin doono.
