Isivavanyeli seSeti yoXinzelelo lweSponge: Umatshini woVavanyo lweSeti yoXinzelelo lweFoam ye-ISO 1856

Intshayelelo: Ukubaluleka kovavanyo lweSeti yokucinezelwa kwezinto zeFoam

Izinto zesiponji kunye ne-foam zisetyenziswa kakhulu kwifenitshala, kumatrasi, kwizihlalo zeemoto, ekupakisheni, nakwiindawo zokufaka ubushushu. Enye yezona zinto zibalulekileyo ekusebenzeni kwezi zinto kukubaiseti yoxinzelelo— ukuguquka okungapheliyo okuhlala emva kokuba isampuli yefoam icinezelwe phantsi kweemeko ezithile kangangexesha elithile kwaye emva koko kuvunyelwe ukuba kubuye.Isivavanyeli seSeti yoXinzelelo lweSpongesisixhobo esikhethekileyo esenzelwe ukulinganisa olu phawu ngokuchanekileyo. Ngokuvavanya ukuba isampuli yefoam ayibuyeli kangakanani kubukhulu bayo bokuqala emva kokucinezelwa, esi sivavanyeli sinceda abavelisi ukuba bahlole umgangatho wezinto, baqikelele ukusebenza kwexesha elide, kwaye baqinisekise ukuhambelana kwemveliso.

Ukuqonda uMgaqo-siseko woVavanyo lweSeti yokuCindezela

IIsivavanyeli seSeti yoXinzelelo lweSpongeyenzelwe kwaye yenziwa ngokuyintloko ngokweemfuno zeIndlela ye-ISO 1856 A, kodwa ingahlengahlengiswa neminye imigangatho yamazwe ngamazwe. Inkqubo yovavanyo ivavanyaukuguqulwa okusisigxinakwezinto zefoam emva kokucinezelwa.

Isishwankathelo seNkqubo yoVavanyo oluPhambili

• Ukulungiselela iSampuli:Isampulu yovavanyo yobukhulu obuchaziweyo isikwa kwizinto ezenziwe ngefoam. Ubukhulu bayo bokuqala bulinganiswa kwiindawo ezininzi.
• Ukuseta ucinezelo:Isampuli ibekwa phakathi kweepleyiti ezimbini ezihambelanayo zesixhobo sokucinezela (isixhobo sokucinezela). Iipleyiti zihlengahlengiswa ukuze zicinezele isampuli ukuya kwipesenti emiselweyo yobukhulu bayo bokuqala - ngesiqhelo50%yobukhulu bayo bokuqala (okanye ezinye iipesenti ezichaziweyo, ezifana ne-25% okanye i-75%, kuxhomekeke kumgangatho).
• Ukulungisa ubushushu:Isixhobo sonke sokucinezela esinomzekelo ocinezelweyo sifakwa kwii-oven elawulwa bubushushuisetiwe kubushushu bovavanyo obufunekayo — kwi-ISO 1856 Indlela A, le yi70 ± 1°CIsampuli ihlala iphantsi koxinzelelo kolu bushushu kangangexesha elithile, ngesiqheloiiyure ezingama-22.
• Ixesha Lokubuyisela Ubude:Emva kwexesha lokufudumeza, isixhobo sokucinezela siyasuswa kwi-oven. Isampuli iyakhululwa ekucinezelweni kwaye ivunyelwe ukuba ibuyele kwimeko yayo eqhelekileyo yelebhu (ngesiqhelo i-23 ± 2°C, i-50 ± 5% RH) kwixesha elithile lokubuyisela — ngesiqheloimizuzu engama-30.
• Umlinganiselo Wokugqibela:Emva kwexesha lokubuyisela kwimeko yesiqhelo, ubukhulu bokugqibela besampuli bulinganiswa kwiindawo ezifanayo nezokulinganisa kokuqala.
• Ubalo:Iseti yoxinzelelo ibalwa njengepesenti yobukhulu bokuqala:

Iseti yoXinzelelo (%) = [(Ubukhulu bokuqala - Ubukhulu bokugqibela) / (Ubukhulu bokuqala - Ubukhulu obuxinzelelweyo)] × 100%

Ixabiso elimiselweyo lokucinezelwa libonisa ukuba igwebu liye laguquka kangakanani ngokusisigxina. Ixabiso elisezantsi lokucinezelwa libonisa iimpawu zokubuyisela ezingcono kunye nokuqina okuphezulu.

Iinkcukacha zobuGcisa eziPhambili

IIsivavanyeli seSeti yoXinzelelo lweSpongeyenzelwe ukuchaneka nokuthembeka engqondweni ukuqinisekisa iziphumo zovavanyo ezichanekileyo neziphindaphindwayo.

• Umlinganiselo woxinzelelo:Ngokwesiqhelo yi-50%, kunye neendlela ezilungisekayo ze-25%, 75%, okanye iireyithingi ezenziwe ngokwezifiso.
• Ubungakanani beSpecial:Ngokwesiqhelo yi-50mm × 50mm okanye i-100mm × 100mm, ubukhulu bayo buqala kwi-10mm ukuya kwi-30mm.
• Ubushushu bovavanyo:70 ± 1°C (ngokwe-ISO 1856 Indlela A).
• Ubude bokucinezelwa:Iiyure ezingama-22 (okanye njengoko kuchaziwe ngumgangatho).
• Ixesha Lokubuyisela Ubukho:Imizuzu engama-30 (okanye njengoko kuchaziwe ngumgangatho).
• Izinto zoMbane wokuCinezela:Intsimbi engagqwaliyo okanye i-aluminium alloy enganyangekiyo kukugqwala, kunye neepleyiti ezichanekileyo ezihambelanayo.
• Ukulinganisa ngokuchanekileyo:Ukulinganiswa kobukhulu obunesisombululo esingu-0.01mm.
