Yang'anani mozungulira. Milatho yomwe mumawoloka, magetsi omwe amawunikira nyumba yanu, zombo zomwe zimanyamula katundu kudutsa nyanja, ndi mapaipi omwe amapangira mafakitale athu - nyumba zazikuluzikuluzi zimagawana mdani wodekha komanso wosalekeza. Ndipo dzina lake ndi dzimbiri. Koma kwa mdani aliyense woopsa, pali chitetezo champhamvu. Chitetezo chimenecho ndi sayansi yodziwika bwino ya utoto wotsutsana ndi dzimbiri wa mafakitale.
Zophimba izi sizingokhala mtundu wokha, komanso ndi makina opangidwa bwino kwambiri, omwe amagwira ntchito ngati chishango chosaoneka chomwe chimateteza umphumphu ndi moyo wautali wa zinthu zomwe dziko lathu lamakono limadalira.
Kumvetsetsa Kudzimbiritsa ndi Dzimbiri
Kudzikundikira kwa dzimbiri ndi njira yachilengedwe yamagetsi pomwe chitsulo choyengedwa bwino—monga chitsulo, chomwe ndi maziko a zomangamanga zamakono—chimabwerera ku mawonekedwe okhazikika a mankhwala, monga oxide yake. Kwenikweni ndi kuyesera kwa chitsulocho kubwerera ku momwe chinalili poyamba mu nthaka.
Dzimbiri ndi dzina lodziwika bwino la dzimbiri la chitsulo ndi zitsulo zake, zomwe zimapangitsa kuti pakhale ma oxide ofiira-lalanje odziwika bwino. Njira yowononga imeneyi yokha ndiyo imayambitsa kuyambika kwa zinthu.
Liwiro la kuukira kumeneku limakulitsidwa ndi zinthu zingapo:
Malo Okhala M'nyanja: Mchere ndi electrolyte yabwino kwambiri, zomwe zimapangitsa kuti nsanja za m'mphepete mwa nyanja, zombo, ndi nyumba za m'mphepete mwa nyanja zikhale zosatetezeka kwambiri.
Mlengalenga wa Mafakitale: Zomera zamankhwala zimatulutsa ma asidi, sulfure, ndi zinthu zina zoipitsa zomwe zimadya kwambiri pamwamba pa chitsulo.
Chinyezi ndi Kusinthasintha kwa Kutentha: Chinyezi chokhazikika komanso kukula/kupindika kwa kutentha komwe kumachitika chifukwa cha kusintha kwa kutentha kumakhudza zophimba ndikuyika chitsulo chatsopano kuti chiwonongeke.
Zotsatira za dzimbiri losalamulirika ndi zoopsa kwambiri: kulephera kwa kapangidwe kake, masoka oopsa achilengedwe chifukwa cha kutayikira kwa ziwiya, nthawi yogwirira ntchito yosakonzekera, komanso ndalama zokonzera zinthu zambiri. Ichi ndichifukwa chake njira yotetezera si njira yongoganizira zokongoletsa zokha; ndi chitetezo chofunikira komanso chofunikira kwambiri paukadaulo.
Chitetezo Chokhala ndi Zigawo Zambiri: Kuchotsa Dongosolo Lophimba
1. Chiyambi:
Choyambira ndiye gawo lofunika kwambiri, chifukwa chimayikidwa mwachindunji pamwamba pa chitsulo chokonzedwa. Ntchito zake sizingakambirane:
Kumatira: Kuyenera kupanga mgwirizano wosasweka ndi chitsulo chopangidwa ndi chitsulo.
Kuletsa Kudzimbidwa: Ma primer ambiri ali ndi utoto wochita kupanga monga zinc phosphate kapena njira zina zopanda poizoni zomwe zimaletsa kuzizira kwa nthaka pamwamba pa chitsulo.
Chitetezo cha Cathodic: Zinc-Rich Primers zimapita patsogolo kwambiri. Tinthu ta zinc mu chophimbacho ndi tosasinthika ku chitsulo. Izi zikutanthauza kuti zinc idzawononga *m'malo mwa* chitsulocho, zomwe zimapereka chitetezo chogwira ntchito ngakhale chophimbacho chawonongeka pang'ono.
2. Chovala Chapakati:
Gawo ili, lomwe nthawi zambiri limakhala ndi epoxy yolimba kwambiri, limagwira ntchito ngati ntchito yeniyeni ya dongosololi. Ntchito zake zazikulu ndi izi:
Chitetezo cha Zotchinga: Chimawonjezera kwambiri makulidwe a filimuyi, ndikupanga chishango cholimba, chosalowa madzi chomwe chimatseka chinyezi, mpweya, ndi mankhwala olowa.
Kulimba: Kumawonjezera kusweka kwakukulu ndi kukana kugwedezeka, kuteteza primer ku kuwonongeka kwa makina.
Kapangidwe: Imapanga malo ofanana, kutseka zolakwika zilizonse zazing'ono ndikupereka gawo loyenera la topcoat.
3. Chovala Chapamwamba:
Chovala chapamwamba ndi gawo lomwe limayang'ana dziko lakunja. Ngakhale kuti chimapereka mtundu womaliza komanso kukongola, ntchito zake zaukadaulo ndizofunikira:
Kukana Nyengo: Yapangidwa kuti isawonongeke ndi kuwala kwa UV, kupewa kutayika kwa choko, kutayika kwa kuwala, komanso kuwonongeka kwa filimu.
Kukana Mankhwala ndi Kutha kwa Madzi: Zimachotsa mankhwala enaake ndipo zimasunga mtundu wake m'malo ovuta.
Kuyera ndi Kusunga Kuwala: M'malo ambiri osungiramo zinthu, malo owala kwambiri komanso osavuta kuyeretsa ndi ofunikira kuti pakhale ukhondo komanso kuwala kuwonekere.
Mitundu ya Zophimba Zamakampani
Kusankha chophimba choyenera cholamulidwa ndi chilengedwe, gawo lapansi, ndi zofunikira pakugwira ntchito.
Zophimba za Epoxy:Kavalo wogwira ntchito kwambiri m'makampaniwa. Amadziwika chifukwa cha kumatira kwawo bwino, kuuma kwawo, komanso kukana mankhwala, zosungunulira, ndi chinyezi. Kufooka kwawo ndi kukana bwino kwa UV, komwe kumayambitsa kusweka ndi kuwonongeka kwa choko.
Zophimba za Polyurethane:Mfumu ya ma topcoats. Ma polyurethane a Aliphatic amapereka kuwala kwapadera komanso kusunga mtundu, ngakhale atakhala ndi UV kwa nthawi yayitali. Amalimbananso kwambiri ndi kukwawa ndi mankhwala, zomwe zimapangitsa kuti akhale abwino kwambiri pa milatho, zida zamafakitale, ndi zitsulo zomangidwa.
Ma Primer Olemera ndi Zinc (ZRPs):Mzere woyamba wotetezera zitsulo m'malo owonongeka. Amapezeka ngati epoxy (organic) kapena silicate (inorganic), ZRPs amapereka chitetezo cha cathodic chodzipereka. Zinc silicates inorganic ndi zolimba kwambiri komanso zotetezeka kutentha, zomwe zimapangitsa kuti zikhale zabwino kwambiri pa sitima zapamadzi, nyumba za m'mphepete mwa nyanja, ndi zomera za petrochemical.
Zophimba za Alkyd:Utoto wachikhalidwe, wopangidwa ndi mafuta womwe ndi wosavuta kugwiritsa ntchito komanso wotsika mtengo m'malo ofatsa, amkati, kapena akumidzi. Kulimba kwawo kochepa komanso kukana mankhwala.
Zophimba za Fluoropolymer (PVDF):Amapereka mphamvu yapamwamba kwambiri ya UV ndi kukana nyengo, zomwe zimagwiritsidwa ntchito pa nyumba zodziwika bwino komwe kukhazikika kwa utoto kwa nthawi yayitali ndikofunikira kwambiri.
Chophimba chapamwamba kwambiri padziko lonse lapansi sichingagwire ntchito ngati chigwiritsidwa ntchito pamalo osakonzedwa bwino. Lamulo lapamwamba la makampaniwa ndilakuti magwiridwe antchito a makina ophimba amadalira 49% pakukonzekera pamwamba ndipo 51% pa chophimba chokha.
Njira yoyamba ndi kuphulika koopsa. Njirayi imachita zinthu ziwiri zofunika: kuchotsa zodetsa zonse: dzimbiri, chitoliro cha mphero, mchere, mafuta, ndi utoto wakale, zomwe zimapangitsa kuti pamwamba pakhale poyera bwino.
Zimapanga mawonekedwe a pamwamba kapena "pattern ya nangula," kukhwima kolamulidwa komwe kumawonjezera kwambiri malo a pamwamba kuti primer igwirepo mwamakina.
Mapeto:
Dongosolo lopaka utoto lokonzedwa bwino komanso logwiritsidwa ntchito bwino limalipira lokha nthawi zambiri ndi:
Kuonjezera Moyo wa Utumiki kuyambira zaka mpaka zaka makumi ambiri.
Kuchepetsa Kwambiri Ndalama Zokonzera ndi Kukonza Zadzidzidzi.
Kuonetsetsa Chitetezo cha Ntchito ndi kupewa kulephera kwakukulu.
Kukulitsa nthawi yogwira ntchito komanso magwiridwe antchito.
