Kwadalwa ngo 2024.03.23
Amathangi E-Enamel Asebenza Kakhulu Okugcina Izimboni Eziyinkimbinkimbi Nezamasipala
Emkhakheni wezingqalasizinda zomhlaba wonke, ukugcinwa kwamanzi amdaka ezimboni ashintsha kalula, izindawo ezilimaza kakhulu ze-biogas, kanye namanzi okuphuza alawulwa kakhulu kudinga impahla edlula imikhawulo yensimbi evamile kanye ne-concrete evuza amanzi. Amathangi e-Enamel—awaziwa kakhulu emkhakheni wezobunjiniyela njengamathangi e-Glass-Fused-to-Steel (GFS)—ayimela isiqongo sobuchwepheshe bokugcina obumodular.
Ithangi le-enamel akulona nje upende; kuyinto eqinile eyenziwe kahle kakhulu. Ngokuhlanganisa ingilazi engaphili ngokwemvelo ku-insimbi enamandla aphezulu, abanikazi bezobunjiniyela bakha umkhumbi wokugcina ohlangana nokuguquguquka nokuvikeleka kwensimbi nokungathathi hlangothi ngokuphelele kwengilazi. Kubanikazi bezobunjiniyela bezemvelo, abahleli bomasipala, kanye nabakhi bezinhlelo ze-EPC, ukukhetha impahla yokugcina ye-GFS kususa izindleko ezinkulu zokugcinwa ezihambisana nokugqoka oketshezi okufakwa ensimini kanye nokudabuka kukakhonkolo.
Njengomdlandla wase-Asia ezinhlelweni zokugcina ezimolulwe ngamabhawodi, i-Shijiazhuang Zhengzhong Technology Co., Ltd (Center Enamel) ichaza izinga lomhlaba wonke lobunjiniyela bamathangi e-enamel, iletha ukugcinwa okufakazelwe efektri, okungadingi ukugcinwa okungaphezu kwamakhilomitha ayi-100 emhlabeni wonke.
1. Isayensi Yezinto Zensimbi: Inqubo Yokuhlanganisa Ingilazi-kuya-Ensimbini
Isici esichazayo esithangi se-enamel yindlela yokukhiqiza yaso. Izendlalelo ezijwayelekile ze-epoxy noma ze-polyurethane zisekelwe ukunamathela komshini (ukuqina kwamanzi) ukuze zinamathisele ensimbi. Ezindaweni ezinobungozi, ukuklwebheka okuncane kuvumela uketshezi ukuthi luhambe ngaphansi kwesendlalelo, lubangele ukugqwala okusheshayo ngaphansi kwesendlalelo.
I-Center Enamel isusa leli phutha ngokuhlanganiswa kwe-thermodynamic eshisayo kakhulu:
● Ukufakwa kwe-Vitreous Frit: Izinsimbi zensimbi ezinekhabhoni ephansi, ezihlanganiswe ne-titanium, zilungiswa ngaphambili futhi zigqokwe nge-silica glass frit engokwemvelo eyakhelwe yona.
● Ukuhlanganiswa kwe-Thermal: Izinsimbi ezigqokwe zishiswa kuhhavini oluqhubekayo oluzenzakalelayo emazingeni okushisa asukela ku-820°C kuye ku-930°C. Kuleli phuzu lokushisa, ingilazi iyancibilika futhi isebenza ngokwemvelo nendawo yensimbi, yakha indawo eyinkimbinkimbi yokuguquguquka.
● Ukuqina kwe-Thermodynamic: Ukwakheka okukhethekile kwe-enamel kuqinisekisa ukuthi i-coefficient yokunweba kwe-thermal ($\alpha$) yengilazi ifana kakhulu ne-substrate yensimbi ($\alpha_{glass} \approx \alpha_{steel}$). Lokhu kuvimbela ungqimba lwengilazi ukuthi lungaqhekeki noma lungahlukani phakathi noshintsho olusheshayo lokushisa kwemvelo noma ukuguquguquka kwesakhiwo ngaphansi komthwalo we-hydrostatic.
2. Ukudlula Amakhemikhali Nokuvikela Imvelo
Ngoba ingaphakathi ethangini liyingilazi ehlanzekile, impahla ayithinteki yizinto eziyimbangela yokubola kwezisekelo ezakhiwe ngendlela evamile:
● Ukubekezelelana Okubanzi kwe-pH: Amafomula e-frit akhethekile e-Center Enamel enza indawo ehlala izinzile ngokuphelele ebangeni elibi lamakhemikhali le-pH 1.0 kuye ku-14.0. Lokhu kuvumela uhlobo olulodwa ethangini ukuthi ligcine izinto ezimuncu kakhulu noma imfucumfucu yezimboni ngokuphepha.
● Ukumelana Nokubola Okubangelwa Amagciwane (MIC): Emadijesta angenamoya kanye nezicelo zamanzi adingekayo, amagciwane okukhiqiza isulfure enza i-sulfuric acid ye-biogenic esikhungweni samathangi. Indawo ye-enamel eshelele kakhulu, engenamigodi ihlinzeka ngamaphuzu okuqala ambalwa ama-biofilms amagciwane futhi ayikwazi ukuhlaselwa yi-acid.
● Ukuqina ku-UV nasezimeni zezulu: Ngokungafani namaplastiki (HDPE) noma ama-epoxy athile achithakachithe futhi aqhekeke ngaphansi kokukhanya kwelanga okunamandla, ingaphandle le-vitreous enamel liyaguquguquka ku-UV ngo-100%, ligcina ubuqotho balo bokwakhiwa nombala wobuhle unomphelo.
3. Mekanika Yokwakhiwa kanye Nomklamo Womfutho Wamanzi
Ihhovisi lobunjiniyela le-Center Enamel lilungisa izindonga zamathangi e-GFS lisebenzisa i-Finite Element Analysis (FEA) ethuthukisiwe ukuphatha imithwalo eqondile yokwakhiwa yizimiso zezimboni ezinokuminyana okuphezulu kanye nezimo zezindawo ezingajwayelekile.
● Ukuhambisana ne-AWWA D103-09 & EN 1090: Imiklamo yethu ihambisana nezindinganiso eziqinile zamazwe omhlaba zokugcina eziboshiwe.
● Ukuhlanganiswa Okuyimodyuli Okungangeni Moya: Amaphaneli e-enamel ahlanganiswa endaweni usebenzisa izinsimbi ezikhethekile ezinamandla aphezulu. Imiphetho evaliwe icindezelwa ngokumelene nezinto zokubopha ezisezingeni eliphezulu (isb., EPDM noma i-Viton) ngaphansi komfutho womshini olungisiwe, uqinisekisa uphawu olungavuza, olungenawo igesi.
4. Ikhadi Lokuhlola Lobuchwepheshe: I-Enamel ngokumelene Nokugcinwa Kwesintu
Ukusiza abaphathi bokuthenga, abaqondisi bezindawo, kanye nonjiniyela bomphakathi ngesikhathi sokufaneleka komthengisi, leli khadi lokuhlola ligqamisa imingcele yokusebenza yezinhlobo ezijwayelekile zokubamba:
Ipharamitha Yenjiniyela Ebalulekile | Amathangi e-Enamel ye-Center GFS | Ins simbi ye-Carbon Eqoqwe ensimini | Ukhonkolo Oqeqebulwe Ngokwesintu |
Isigaba Sokugqoka Esivikelayo | Ukuhlanganiswa Kwama-molecule Angaphandle Kwemvelo | Ukuqeqebula Okungamanzi Okusebenza Ens imbi | Akukho (Isakhiwo Esine-porous) |
Ingozi Yokugqwala Ngaphansi Kwesikhumba | Iziro (Ukubopha Kwamakhemikhali) | Phezulu (Idinga i-sandblasting) | Ayisebenzi (Ingozi yokubola) |
Ukumelana Namakhemikhali | Okuphezulu Kakhulu (pH 1.0 - 14.0) | Okulinganiselayo (pH 4.0 - 9.0) | Kuncane (Kubuthakathaka ekushisweni yi-acid) |
Izinto Zokufakwa | Kuyashesha Kakhulu (Kufakwa kusuka phezulu kuye phansi) | Kuyabambezeleka (Izinyanga zokusebenza ngokushisa) | Kuyabambezeleka Kakhulu (Ukuqina kwezinsuku ezingama-28+) |
Impilo Yesevisi Yempahla | Impilo Eqinisekisiwe Yeminyaka engama-30+ | Iminyaka eyi-15–20 | Iminyaka eyi-15–20 |
Ukuhanjiswa Kwezindawo Eziyinhloko | Kungahlakazwa/Kungasuswa ngo-100% | Impahla Engashukunyiswa | Impahla Engashukunyiswa |
5. Ukuqinisekiswa Kwekhwalithi Okujwayelekile: Ukuhlolwa Kwe-Holiday Okungu-1500V+
Umenzi wezinto zokubamba ezisezingeni eliphezulu akaze ayishiye ikhwalithi yokugqoka ekuhlolweni okubonakalayo noma ukukhethwa kwamaqoqo ngokungahleliwe. I-Center Enamel iphoqelela inqubo yokuhlola yasefektri engu-100% engonakalisi ukuthola iphaneli ngayinye ye-GFS.
● Ukuhlolwa Kwe-Voltage Ephezulu: Ochwepheshe basefektri badlulisa ugesi okhethekile we-voltage ephezulu—okulinganiswe ngokuqinile phakathi kuka-1,500V no-1,800V—phezu kwawo wonke umhlahlandlela we-enamel plate.
● Isiqinisekiso Sokungabi Namaphutha: Uma ugesi uthola noma iyiphi imbobo encane kakhulu noma ukuphazamiseka emgqeni wokuvikela wokugqoka, iphaneli iyalahlwa ngokushesha. Le nqubo iqinisekisa ukuthi insimbi esetshenzisiwe ayikaze ivezwe ezintweni eziyingozi, iqinisekisa umjikelezo wokusebenza ongaphazamiseki.
Isinqumo Sobunjiniyela Esihlanganisiwe
Ukukhetha ithangi le-enamel (GFS) kufuna ukushintsha umbono kusuka ekuchithweni kwemali yokuqala kuya ekusebenzeni kwesikhathi eside, ukudlula kwamakhemikhali, kanye nesivinini sokuthunyelwa okuyimodyuli. Ezindaweni zamanzi zikamasipala zesimanje, izitshalo ezinkulu zokukhiqiza, kanye nezindawo ezinkulu zokukhiqiza amandla e-bioenergy, ukubambisana nomholi oqeqeshwe ngamazwe omhlaba njenge-Center Enamel kumele kube utshalomali olubalulekile lokunciphisa ubungozi. Ngokusebenzisa ukuqina okungenakuqhathaniswa kobuchwepheshe be-Glass-Fused-to-Steel, izindawo ziqinisekisa ukuthobela ngokuphelele imvelo, ziqede ukulahleka kwesikhathi ngenxa yokugcinwa okuphindaphindayo, futhi zivikele ingqalasizinda ebalulekile isikhathi esingaphezu kweminyaka engamashumi amathathu.
