Ingabe Ama-GFS Silos Anesitifiketi Sekhwalithi Yokudla Esetshenziselwa Ukugcina Okusanhlamvu Nefulawa
Yebo, amasilo e-glass-fused-to-steel angahlinzekwa ngokuhambisana nezinga lokudla. Ingqimba ye-enamel ihlanganiswa nensimbi ku-820 kuya ku-930 °C ngobukhulu obungu-0.25 kuya ku-0.45 mm, ikalwa ngaphezu kuka-3,450 N/cm², futhi inikeza indawo ebushelelezi engasebenzi engaphansi kuka-0.8 µm Ra engakhiphi izinhlayiya, engasekeli ukuhlala kwamagciwane noma isabele nomkhiqizo. I-Center Enamel ihlinzeka ngezidingo ze-FDA, LFGB, NSF/ANSI 61 kanye ne-WRAS kuye ngohlelo lokuxhumana, ngaphansi kohlelo lokuphatha lwe-ISO 9001 kanye ne-ISO 45001. Isitifiketi sihlanganisa into kanye nendawo, hhayi inhlanzeko yenqubo ezungezile.
Umbuzo ufika ngendlela ethile kuhlu lwezinto ezithengwayo isizini ngayinye: ingabe lezi zikhwama zokugcina zokudla zisezingeni lokudla ngempela, noma ingabe lokho kumane kuwumugqa osencwadini yokukhangisa? Unjiniyela ocacisayo ngokuvamile unomcwaningi wezempilo amlindile kanye nesiphathimandla senqubo esicela imibhalo, futhi impendulo eqotho kufanele yehlukanise izinto ezintathu ezijwayele ukuhlanganiswa ukukhangisa — into ethinta indawo, isitifiketi sokuhambisana ngaleyo ndawo, kanye nokuhlanjululwa kwesitshalo uqobo. Ingilazi ehlanganiswe nensimbi iyinto esemthethweni ethinta ukudla, kodwa okwenza kwamukeleke ukuhlanganiswa kwamakhemikhali kanye nokuqedwa kwendawo, hhayi iqiniso lokuthi amaphaneli aboshelwe ndawonye.
Ingaphezulu yilona isitifiketi esikhuluma ngalo ngempela
Izinga lokusebenza elilingana nokudla ku-silo ye-enamel ehlanganisiwe liqala esinyathelweni sokuhlanganisa, hhayi esinyathelweni sokumboza. Ku-820 kuya ku-930 °C ingilazi ihlangana ne-steel substrate futhi akukho-binder ephilayo, akukho-primer futhi akukho-film eyomile phakathi. Lokho kubalulekile ngoba zonke izingqimba eziphilayo emkhunjini othinta ukudla ziyinto engase i-hydrolyze, i-craze, i-delaminate noma ikhiphe umbala emkhiqizweni. I-enamel ayinazinto eziphilayo futhi ayisebenzi ku-pH esukela ku-1 kuya ku-14, ngakho i-brine ene-asidi, ukuwashwa nge-alkaline kanye nokugezwa nge-caustic eshisayo konke kuhlangana nendawo efanayo ezinzile. Ukujiya kwengqimba okungu-0.25 kuya ku-0.45 mm okunesilinganiso esingaphezu kuka-3,450 N/cm² ekugobeni nasekucindezelweni kusho ukuthi ukushaywa okujwayelekile okuvela ekuhambeni kwezinhlamvu noma kwama-Pellet akukunciphisi endaweni njengoba ingenziwa yi-film yepende encane.
Lokho okushiwo yizitifiketi nalokho ezingakusho
I-FDA, i-LFGB, i-NSF/ANSI 61 kanye ne-WRAS ngayinye iphendula umbuzo ohlukile, futhi akukho neyodwa yazo eqinisekisa ithangi lilonke. I-FDA ne-LFGB yizinhlelo zokuxhumana nokudla ezivame ukubhekiselwa kuzo mayelana nendawo ethinta umkhiqizo, ezihlanganisa ukuthi into ingaba yini futhi akumele idlulele ini ekudleni. I-NSF/ANSI 61 ne-WRAS yizinhlelo zamanzi okuphuza, ezisebenza uma isitsha esifanayo noma i-gasket efanayo kanye nento yokuvimbela izogcina amanzi okuphuza. I-CE (EN 1090) ne-ISO 28765 zihlanganisa umsebenzi wokwakhiwa nokwenziwa, kanti i-ISO 9001 ne-ISO 45001 zihlanganisa uhlelo lokuphatha olusetshenziswa umenzi. Ngakho-ke isicelo esithembekile sicela isitifiketi esihambisana nomsebenzi wokuxhumana, kanye nombiko wokuhlolwa kwepuleti kanye nesilinganiso sokungalingani kwendawo — hhayi nje isimangalo esijwayelekile sokuthi kusezingeni lokudla.
Ukuqina, ukuhlanzeka kanye nendlela yokwehluleka ebalulekile
Indawo ingaba sezingeni lokudla kuphela uma ingahlanzwa ngesikhathi esikhona. Umndeni we-enamel ehlanganisiwe usebenza ngobukhulu obungaphansi kuka-0.8 µm Ra, okuphansi ngokwanele ukuthi umkhiqizo ungangeni odongeni futhi ukugeza akudingi ukukhuhla. Ubukhulu futhi yisizathu esenza isilo sisebenze kahle ezintweni ezomile, lapho udonga olugcotshiwe noma olwenziwe nge-galvanized lungaqongelela khona insalela eba yisikhunta nendawo yokuhlala yezinambuzane bese iphinda ingcolise ukulethwa okulandelayo. Izindlela ezimbili zokwehluleka okufanele ziqashelwe zihlala zifana noma kuphi emndenini: ukuhlukana ekuhlanganeni kwe-fusion uma isisekelo senza igobolondo lingabi yindilinga, kanye nokwakheka kwezimbobo ezincane ezivela ekushayweni okwenzeka endaweni ngesikhathi sokuphathwa kwamaphaneli. Kokubili kubanjwa ngaphambi kokuthunyelwa ngokuhlolwa kwe-spark ye-1500 V DC kulo lonke ipuleti eline-enamel, okuwukuhlolwa okuguqula isimangalo sibe ubufakazi.
Isisekelo esiyisicaba noma isisekelo se-hopper kushintsha isithombe senhlanzeko
Ijiyometri yaphansi yisinqumo sokuphepha kokudla, hhayi kuphela esokukhiqiza. Ingaphansi eliyisicaba likhipha emgodini ophakathi nendawo noma ephasishi futhi lishiya insalela eshanyelwe, okuthi kukho okusanhlamvu okomile kube kuncane kodwa kungabi zero futhi kube yinkinga yokungcola okuhlanganayo lapho isilo sisetshenziselwa izinga elingaphezu kwelilodwa. Ingaphansi le-hopper noma le-funnel liqhubela insalela eceleni kwe-nil futhi liyimpendulo efanele yembewu, amazinga amaningi noma into enenani eliphezulu lapho umkhondo weqoqo langaphambili kuwukwehluleka kwencazelo. I-hopper yengeza ukuphakama kwesisekelo nensimbi yesakhiwo futhi idinga ukuqoqwa kwayo kothuli endaweni yokuphuma, ngakho-ke isinqumo kufanele siphikiswe ngezinga lensalela inqubo engalibekezelela — futhi ukuqoqwa kothuli kuyingxenye yenhlanzeko yokudla, ngoba uthuli lokusanhlamvu olusemoyeni endaweni ephezulu kuyinto yokungcola kanye nendaba yothuli oluvuthayo.
