>Kusankha zida zopangira ukhondo

Choyamba: Gulu la Wood:
Anticorrosive nkhuni zolimba: zachilengedwe, zachilengedwe komanso zotetezeka (mitengoyo ili mumtundu wake woyambirira, wobiriwira pang'ono).Ndipotu, kuwonjezera pa makhalidwe odana ndi dzimbiri, nkhuni zotsutsana ndi zowonongeka zimakhalanso ndi makhalidwe abwino komanso kukana kutayika.Panthawi imodzimodziyo, imatha kulepheretsa kusintha kwa chinyezi cha nkhuni zomwe zimagwiritsidwa ntchito komanso kuchepetsa kuchuluka kwa nkhuni zowonongeka.Mitengo yodziwika bwino yapakhomo yolimbana ndi dzimbiri imakhala ndi zida ziwiri: Russian Pinus sylvestris ndi Nordic Scots Pine.Mitengo yotetezedwa yopangidwa ndi pine yaku Russia ndiyo njira yosungiramo mitengo yamitengo yotumizidwa kunja ku China, ndipo ambiri aiwo amathandizidwa ndi othandizira a CCA.Mitengo yotetezera yopangidwa ndi Nordic red pine imasungidwa kunja, ndipo nkhuni zotetezera zomwe zimatumizidwa kudziko kuti zigulitsidwe mwachindunji zimathandizidwa ndi ACQ agents ndipo nthawi zambiri zimatchedwa "matabwa aku Finnish".Anthu anazolowera kutcha matabwa oteteza zinthu kuti asawonongeke ngati mitengo ya ku Finland.Ndipotu izi ndi zolakwika.Ndikosavuta kwa anthu omwe samvetsetsa nkhuni zosungirako kuti asamvetse.
Chachiwiri: Chitsulo chosapanga dzimbiri:
Chitsulo cha dzimbiri ndi asidi chimafupikitsidwa ngati chitsulo chosapanga dzimbiri.Pamwamba pa mbale yachitsulo chosapanga dzimbiri ndi yosalala ndipo imakhala ndi pulasitiki yapamwamba, yolimba komanso mphamvu zamakina.Imagonjetsedwa ndi dzimbiri ndi ma acid, mpweya wa alkaline, njira ndi zina.Ndi chitsulo cha alloy chomwe sichapafupi kuchita dzimbiri, koma chimakhala chosachita dzimbiri.Chitsulo chachitsulo chosapanga dzimbiri ndi mbale yachitsulo yomwe imagonjetsedwa ndi zofooka zofooka monga mpweya, nthunzi ndi madzi, pamene zitsulo zosagwira asidi zimatanthawuza mbale yachitsulo yomwe imagonjetsedwa ndi asidi, alkali, mchere ndi zinthu zina zowononga mankhwala.Amapangidwa ndi chitsulo chosapanga dzimbiri komanso chitsulo chosamva acid.Chitsulo chomwe chimatha kulimbana ndi dzimbiri mumlengalenga chimatchedwa chitsulo chosapanga dzimbiri, ndipo chitsulo chomwe chimatha kukana kuwonongeka kwa media media chimatchedwa chitsulo chosamva acid.Nthawi zambiri, chitsulo chokhala ndi Wcr choposa 12% chimakhala ndi chitsulo chosapanga dzimbiri.Malinga ndi microstructure pambuyo mankhwala kutentha, zitsulo zosapanga dzimbiri akhoza kugawidwa m'magulu asanu: ferritic zosapanga dzimbiri, martensitic zosapanga dzimbiri zitsulo, austenitic zitsulo zosapanga dzimbiri, Austenitic-ferritic zosapanga dzimbiri zitsulo ndi precipitated carbide zitsulo zosapanga dzimbiri.
Chifukwa chitsulo chosapanga dzimbiri chimakhala ndi kukana kwa dzimbiri, kukhazikika, kugwirizana, komanso kulimba pakutentha kwakukulu, chimagwiritsidwa ntchito kwambiri m'makampani olemera, mafakitale opepuka, mafakitale ofunikira tsiku ndi tsiku, zokongoletsera zomanga ndi mafakitale ena..
Chachitatu: Gulu la mapepala otentha a dip:
Pepala lachitsulo chopangidwa ndi chitsulo ndi kuteteza dzimbiri pamwamba pa pepala lachitsulo ndikutalikitsa moyo wake wautumiki.Pamwamba pazitsulo zachitsulo zimakutidwa ndi chitsulo chachitsulo.Chitsulo chamtundu uwu chimatchedwa galvanized sheet.
Malinga ndi njira zopangira ndi kukonza, zitha kugawidwa m'magulu otsatirawa:
①Zitsulo zovimbika zotentha.Chitsulo chochepa kwambiri chimamizidwa mumadzi osungunuka a zinki, kotero kuti mbale yachitsulo yopyapyala yokhala ndi zinki imamatiridwa pamwamba.Pakali pano, njira yopititsira patsogolo yowonjezera imagwiritsidwa ntchito makamaka popanga, ndiko kuti, pepala lachitsulo chokulungidwa limamizidwa mosalekeza mumtsuko wamakabati ndi zinki wosungunuka kuti apange pepala lachitsulo;
②Chitsulo chopangidwa ndi malata.Chitsulo chamtunduwu chimapangidwanso ndi njira yoviyira yotentha, koma ikatuluka mu thanki, imatenthedwa mpaka pafupifupi 500 ℃ nthawi yomweyo kupanga filimu ya aloyi ya zinki ndi chitsulo.Mtundu uwu wa kanasonkhezereka pepala ali wabwino utoto adhesion ndi weldability;
③Chitsulo chamagetsi chamagetsi.The kanasonkhezereka zitsulo pepala opangidwa ndi electroplating njira ali workability wabwino.Komabe, zokutira ndizochepa, ndipo kukana kwa dzimbiri sikwabwino ngati pepala lothirira lotenthetsera;
④Chitsulo chachitsulo chambali imodzi komanso chambali ziwiri.Single-sided galvanized steel sheet ndi chinthu chomwe chimapangidwa ndi malata mbali imodzi yokha.Mu kuwotcherera, kupenta, odana ndi dzimbiri mankhwala, processing, etc., ali bwino kusinthasintha kuposa mbali ziwiri malata pepala.Pofuna kuthana ndi zophophonya za unncoated nthaka mbali imodzi, pali mtundu wina wa kanasonkhezereka pepala TACHIMATA ndi woonda wosanjikiza nthaka mbali inayo, ndiko kuti, mbali ziwiri zosiyana kanasonkhezereka pepala;
⑤Aloyi ndi zitsulo zopangidwa ndi malata.Amapangidwa ndi zinki ndi zitsulo zina monga aluminiyamu, lead, zinki, ndi zina zambiri kuti apange ma alloys kapena mbale zachitsulo zophatikizika.Chitsulo chamtundu uwu sichingokhala ndi ntchito yabwino kwambiri yotsutsa dzimbiri, komanso imakhala ndi ntchito yabwino yokutira;
Kuwonjezera pa mitundu isanu yomwe ili pamwambayi, pali mapepala achitsulo amtundu, mapepala osindikizidwa osindikizidwa, ndi mapepala a PVC opangidwa ndi malata.Koma pakali pano omwe amagwiritsidwa ntchito kwambiri akadali otentha-kuviika kanasonkhezereka pepala.

Chachinayi: Pulasitiki
Chifukwa cha pulasitiki, chimatchedwa nkhokwe yapulasitiki.The zikuchokera: mkulu-kachulukidwe polyethylene HDPE kapena polypropylene PP polypropylene awiri atsopano mapulasitiki.
Mawonekedwe:
(1) Kukana kwa asidi, kukana kwa alkali, kukana kwa dzimbiri komanso kukana kwanyengo kwamphamvu;
(2) Mapangidwe akona ozungulira a doko loperekera ndi otetezeka komanso osapindulitsa;
(3) Pamwambapo ndi yosalala komanso yoyera, kuchepetsa zotsalira za zinyalala komanso zosavuta kuyeretsa;
(4) Ikhoza kuikidwa pa wina ndi mzake, yomwe ili yabwino kwa mayendedwe ndi kusunga malo ndi mtengo;
(5) Angagwiritsidwe ntchito bwinobwino mkati kutentha osiyanasiyana -30 ℃ ~ 65 ℃;
(6) Pali mitundu yosiyanasiyana yomwe mungasankhe, yomwe ingagwirizane ndi zosowa zamagulu;
(7) Amagwiritsidwa ntchito kwambiri m'malo osiyanasiyana, ndipo amathanso kugwiritsidwa ntchito posankha zinyalala, monga katundu, fakitale, ukhondo, etc.

Ubwino:
Zinyalala za pulasitiki ndizosavuta kukonza ndipo zimapangidwa ndi zinthu zopulumutsa mphamvu.Pogwiritsidwa ntchito, sikuti imangochepetsa ndalama zambiri, komanso imakhala ndi chiwonetsero chabwino kwambiri cha moyo wautumiki.Zinyalala zapulasitiki zimakhalanso ndi chiwonetsero chabwino pakuyeretsa kwambiri.Timakonda kutaya zinyalala m’chinyalala.Kwa ana ambiri tsopano, idzakhalanso ndi tanthauzo labwino la maphunziro, zomwe zimachititsa kuti zigwiritsidwe ntchito.Amawonetsa njira yosiyana yogwiritsira ntchito zipangizo.Kutsuka mosavuta ndi mwayi wa zinyalala za pulasitiki, zomwe zikuwonetsa malingaliro osavuta kugwiritsa ntchito a zinyalala zomwe zikugwiritsidwa ntchito.
