Ilangatye lobungqina bocingo olunomnatha ss umnatha ngefreyimu yase China
Umnatha wocingo lokuthintela amadangatye, ngamanye amaxesha okwaziwa ngokuba yi-'Davy lamp gauze', isetyenziswa njengekhusi phakathi kwesibambisi somlilo.
Umoya (kunye nasiphi na isidambisi mlilo okanye umphunga otshayo okhoyo) udlula kwimingxuma yomnatha ngokukhululekileyo ngokwaneleyo ukuxhasa ukutsha, kodwa imingxuma engaphakathi komnatha wocingo olulukiweyo mihle kakhulu ukuvumela ilangatye ukuba lisasazeke kwaye livuthe nawuphi na umphunga ovuthayo ongaphandle komnatha.
Ngenxa yezakhiwo zayo ezikwaziyo ukumelana nomlilo, i-Locker flame proof wire mesh wire mesh iqhele ukusetyenziswa njengobungqina bomlilo ngaphakathi kuluhlu olubanzi lwamashishini kubandakanya i-petrochemical, i-marine, izithuthi, ukufakelwa koomatshini kunye nombane. Isebenza ngokukodwa kugcino olukhuselekileyo, ukuthuthwa kunye nokulungiswa kolwelo olunokutsha okanye iigesi.
Iingozi zokuqhushumba kothuli zikholisa ukwenzeka kwimibhobho yokugawula uthuli lwengqolowa, okubangela iingozi ezinkulu kunye nelahleko yepropathi. Kweli phepha, umbhobho othe nkqo weqonga lokulinga ukutsha lasekwa ukuze kufunyanwe iziphumo zeemeko zokusebenza kunye neeparamitha zomaleko ombini womnatha wocingo olusasaza amadangatye othuli lwengqolowa. Iziphumo zibonisa ukuba i-mesh yocingo oluphindwe kabini lunempembelelo ecacileyo yokunciphisa ilangatye lokusasazwa kothuli lwengqolowa. Xa kudityaniswa inani elifanayo le-mesh, zombini iqondo lobushushu ledangatye eliphezulu kunye nesantya esiphezulu sokusasaza idangatye lehlile ngokunyuka kwenani le-mesh, kwaye isenzeko sokucinywa komlilo kwenzeka kwi-80 mesh. Ekudityanisweni kwamanani ahlukeneyo e-mesh, ukushisa kwelangatye kwi-upper-density kunye ne-low-sparseness indibaniselwano iphantsi kunoko kwi-upper-sparseness kunye ne-low-density indibaniselwano phantsi kwazo zonke iimeko zokusebenza. Umahluko weqondo lokushisa lomlilo (ΔT) ukhula ngokuthe ngcembe ngokunyuka kwenani le-mesh, kwaye ubuninzi be-ΔT bubonakala kumahluko we-mesh ye-40 mesh. Njengoko umgama wokuhlukana ukhula, ukushisa kwelangatye kunyuka, kwaye umphumo wokunciphisa ungcono kumgama wokuhlukana kwe-1 cm. Incopho yoxinzelelo lokutsha ihambelana kakubi nomgama wokwahlula.
Umnatha wocingo wokuqinisekisa amadangatye uneempawu zokuchasana nokugqwala kunye nokumelana ne-oxidation, i-solder joints, amandla okuqina aqinile, umphezulu oqaqambileyo, ukuxhathisa okugqwesileyo, kunye nezinye iimpawu. Imveliso icutshungulwa ngobuchwephesha be-automated mechanical, kunye ne-mesh surface egudileyo, isakhiwo esomeleleyo kunye nengqibelelo eqinile, nokuba inxalenye yokusikwa okanye inxalenye yoxinzelelo ayiyi kubangela ukuphumla.
