Ekipande ekifukiddwa mu mazzi agookya .

Hot dip galvanized sheet zikolebwa nga zinnyika koyilo z’ekyuma ezirongooseddwa mu mazzi ga zinki agasaanuuse olwo oluwuzi lwa zinki ne lubikkibwa kyenkanyi ku ngulu kwa koyilo z’ekyuma, bwe kityo ne kitereeza okuziyiza okukulukuta n’obulamu bw’ekyuma. Hot-Diipu galvanized steel coils zitera okukozesa hot-emiguwa egy’ekyuma egyayiringisibwa oba-emiguwa egy’ekyuma egyayiringisibwa nga substrates. Substrate yeetaaga okusooka okuyonjebwa n’okulongoosebwa okukakasa nti layeri ya zinki enyweza bulungi. Olwo koyilo z’ekyuma ezirongooseddwa ne zinywera mu mazzi ga zinki agasaanuuse olwo layeri ya zinki n’ebikka kyenkanyi ku ngulu w’ebikondo by’ekyuma. N’ekisembayo, koyilo z’ekyuma ezikoleddwa mu galvanized zinyogozeddwa ne ziggwa, gamba ng’okuleega n’okusala.

1. Okugeraageranya enkola y’okufulumya .

Hot-Dip galvanizing: Ekyuma kinywera mu zinki esaanuuse ku diguli nga 450 . Enkola y’ebyuma ekola zinki-oluwuzi lwa aloy olw’ekyuma (30-300μm thick). Kungulu kuba kwa maanyi era kuyinza okwoleka ebiwujjo oba obubonero bw’amazzi.

Ennyogovu-Dipa galvanizing: Zinc ions ziteekebwa ku kyuma kungulu nga ziyita mu masanyalaze (3-15μm obuwanvu). Engulu eweweevu era esobola okulabika mu langi ez’enjawulo (nga eza kyenvu-eza kiragala n’enjeru eya bbululu).

2. Enjawulo mu nkola y’emirimu .

Ebifaananyi Ebiyokya-Diita ekipande ekikoleddwa mu galvanized Cold-Diita galvanized sheet .

Okuziyiza okukulukuta: kwa maanyi nnyo (obulamu obw’ebweru: emyaka 20-50)

Obulamu obunafu (Obulamu obw’omunda: Emyaka 3-5)

adhesion: aloy bond, si kyangu kufuukuula .

Enywezeddwa mu mubiri, nnyangu okufuukuula .

Processability: Tekisaanira kussa sitampu mu butuufu .

Esaanira okukola oluvannyuma .

3. Enkola eza bulijjo .

Hot-Dipa galvanized sheet: ebizimbe ebibikkuddwa mu mbeera ezikosa, gamba ng’eminaala gy’amasannyalaze, ebikuuma oluguudo olukulu, n’ebibanda.

Ennyogovu-Dipa galvanized sheet: ebisenge by’ebyuma, ebitundu by’amasannyalaze, n’ebitundu eby’okuyooyoota munda, awali obutuufu obw’okungulu obw’okungulu.

4. Ensimbi n’obutonde bw’ensi .

Hot-Dip galvanizing erina omuwendo omutono ku buli yuniti (0.5-2 RMB/kg), naye yeetaaga okussaamu ebyuma ebinene era ekola enkuba ya asidi ne zinc slag.

Cold-Dip galvanizing erina ssente nnyingi ez’okulongoosa (3-8 RMB/kg), naye era kizibu okujjanjaba n’amazzi amakyafu agakola amasannyalaze.

1. Enjawulo mu nsaasaanya esooka .

Enkola obuzibu .

Okwokya-okusitula galvanizing kyetaagisa waggulu {-okusaanuuka kwa zinki (450℃) n’okujjanjaba emirundi mingi- (okufumba n’okufuumuuka). Kino kyetaagisa okussaamu ebyuma ebinene n’okukozesa amaanyi amangi, ekivaamu okusaasaanya yuniti nga 20-40 yuan buli square mita.

Ennyogovu-Dipa galvanizing, ekozesa okuteekebwawo kw’amasannyalaze, egaba enkola ennyangu nga ekozesa amaanyi matono, naye nga yeesigamye ku ddagala (nga zinc salt solutions). Omuwendo gwa yuniti guli nga 3-8 yuan buli square meter.

Enkozesa y’ebintu .

Obugumu bwa zinki obw’ebbugumu ery’ebbugumu-obuwanvu butuuka ku 50-100μm, era okukozesa zinki kukubisaamu emirundi 5-10 okusinga okw’okusengejja okw’ennyogoga, ekivaamu omuwendo gw’ebintu ebingi.

Ennyogovu-Diidi galvanizing, ate nga 5-15μm obuwanvu bwokka, yeetaaga high-obulongoofu, ekivaamu omuwendo gw'ebintu okutwalira awamu ogwa wansi okusinga hot-dip galvanizing.

II. Okugerageranya omuwendo omuwanvu-Termu .

Obulamu bw’okuweereza n’okuddaabiriza .

Hot-Dip galvanizing erina obulamu bwa 20-50 emyaka mu mbeera ez'ebweru, nga kyetaagisa kumpi okuddaabiriza era ekivaamu ssente entono ez'ekiseera ekiwanvu okutwalira awamu.

Cold-Dip galvanizing erina obulamu bwa myaka 3-5 gyokka era yeetaaga okuddamu okusiiga oba okukyusa enfunda eziwera mu mbeera ezirimu obunnyogovu, ekiyinza okuvaamu ssente nnyingi ez’okuddaabiriza okusinga okusinda mu bbugumu.

Okukwata ku kusaba .

Hot-Dip galvanizing esaanira embeera ezikosa ennyo (nga ebibanda n’ebifo eby’amasannyalaze), nga waliwo ssente nnyingi ezisookerwako naye nga zisinga kugula-obulungi.

Cold-Dip galvanizing esaanira ebitundu ebituufu eby’omunda (nga ebyuma by’omu maka n’ebitundu eby’amasannyalaze), nga biwa enkizo enkulu ennyimpi-omuwendo gw’ensimbi mu term.

iii. Ensonga endala ezifuga .

Ebisale by’obutonde: ebibuguma-okusitula okusinda kwetaaga okusuula enfuufu ya asidi ne zinki slag, ate nga nnyogovu-okusitula galvanizing kyetaagisa okusuula amazzi amakyafu agakola amasannyalaze, byombi byongera ku nsaasaanya enkweke.

Workpiece Size: Hot-Dip galvanizing is more economic ku bitundu ebinene, ate nga ennyogovu-Dip galvanizing ekuwa okukyukakyuka okusingawo eri ebitundu ebitono.

Mu bufunzi

Short-Term Cost: Cold-Dip galvanizing ekuwa ssente entono (nga 1/3 -1/5 eza hot-dip galvanizing).

Long-Term Cost: Hot-Dip galvanizing ekuwa omulimu ogw'oku ntikko (okuddaabiriza okutono n'obulamu obuwanvu).

Omusingi gw’okulonda: Kukulembeza anti-ebyetaago by’okukulukuta (ebbugumu-Dipa galvanizing for outdoor use), processing accuracy (Cold-Dip galvanizing for precision) ne budget.
