Wopanga chitoliro chopanda dzimbiri
Chitoliro chachitsulo cha anticorrosive chimatanthawuza chitoliro chachitsulo chomwe chimakonzedwa ndi anticorrosive process, chomwe chingalepheretse kapena kuchedwetsa zomwe zimachitika chifukwa cha mankhwala kapena ma electrochemical pamayendedwe ndi ntchito. Malinga ndi ziwerengero za ku China, kutayika kwachuma kwachuma kwa dzimbiri kwa chitoliro ku China kumapitilira 280 biliyoni chaka chilichonse.
Pakali pano, kutayika kwapachaka kwapadziko lonse chifukwa cha kuwonongeka kwa chitoliro chachitsulo ndikwambiri kuposa madola 500 biliyoni aku US. Anticorrosive zitsulo chitoliro angathe kuteteza kapena kuchepetsa dzimbiri, kutalikitsa moyo utumiki wa chitoliro zitsulo ndi kuchepetsa ntchito mtengo chitoliro zitsulo.
Kupanga
Amapangidwa ndi aliphatic polyurethane prepolymer, epoxy resin, utoto wapamwamba kwambiri, zowonjezera ndi zosungunulira. Amagwiritsidwa ntchito makamaka polimbana ndi dzimbiri za zida zomwe zimalumikizana ndi chakudya ndi madzi akumwa, mapaipi otumizira madzi ndi kugawa komanso payipi yamadzi akumwa.
Kachitidwe
Utoto ndi luso interpenetrating maukonde polima, amene amayamba polymerization firiji. Maukonde awiriwa amatha kuphunzira kuchokera kwa wina ndi mnzake ndikupanga mgwirizano. Kanemayo ndi wopanda poizoni, mkulu olimba ndi otsika mamasukidwe akayendedwe. Ndi anti- dzimbiri ❖ kuyanika ndi zomatira amphamvu, mphamvu mkulu, mphamvu kuvala kukana, hydrolysis kukana, dzimbiri kukana, kukana madzi ndi kukana nyengo, ndipo ali ndi zofunika otsika kuchotsa dzimbiri pamwamba pa zitsulo dongosolo, Kutentha kwa utumiki kungakhale mu osiyanasiyana - 20 ~ 120 ℃.
Zizindikiro zaukadaulo
1. Kuyanika nthawi: pamwamba kuyanika kwa 30min ndi olimba kuyanika kwa 6-24h
2. kusinthasintha: 1mm
3. Kukana kwamphamvu: 50cm
4. Kukhazikika: Gawo 1
4. Kumanga ndi kusunga
(1)Pamaso pa kujambula, pamwamba pa chitsulo m'munsi ayenera kusamalidwa kwa Sa2.5. Ndizoletsedwa kubweretsa madzi, fumbi ndi mafuta pomanga kuti zitsimikizire mtundu wa penti.
(2) Gawo la zokutira ndi: chigawo A (chinthu choyambira), chigawo B (chochiritsira) = 9kg utoto: 1kg yochiritsa (kapena kumanga molingana ndi gawo lomwe ladziwitsidwa ndi fakitale yathu).
(3)Njira yofananira yomanga ili motere: tsegulani kutsegula kwakukulu kwa chigawo A, onjezerani gawo B mu chigawo A, ndikusakaniza bwino. Pambuyo kuchiritsa kwa mphindi 30, zokutira zitha kuchitidwa.
(4)Izi zimafunika kukonzedwa ndi kugwiritsidwa ntchito nthawi iliyonse, ndipo zokutira zoyenera ziyenera kugwiritsidwa ntchito mkati mwa maola asanu ndi limodzi. Zida zosamalizidwa ziyenera kusindikizidwa ndikusungidwa.
(5)Ntchito yomanga idzayimitsidwa m'masiku amvula kapena chinyezi chikakhala chachikulu kuposa 75%. Kwa magawo omwe ali ndi sing'anga yowononga kwambiri, tikulimbikitsidwa kugwiritsa ntchito malaya angapo a utoto.
(6) Chogulitsacho chiyenera kusungidwa pamalo ozizira ndi owuma kuti asatengere kuwala kwa dzuwa, kupatulapo gwero lamoto komanso kukhala kutali ndi gwero la kutentha.
(7)Nthawi yosungira ndi miyezi 12. Pambuyo pa kutha, mitundu yosiyanasiyana yaukadaulo idzawunikidwa. Ngati akwaniritsa zofunikira za index, akhoza kupitiriza kugwiritsidwa ntchito.
Fusion bonded epoxy powder, yomwe imadziwikanso kuti thermosetting epoxy resin heavy-duty anti-corrosion powder, ndi zinthu zolimba zomwe zimatengedwa ndikubalalika ndi mpweya monga chonyamulira. Amagwiritsidwa ntchito pamwamba pa zitsulo zowonongeka, zosungunuka, zowonongeka ndi zolimba kuti apange chophimba chofanana. Anti corrosion ndi chotchinga choletsa dzimbiri cholemetsa chomwe chimapangidwa pakutentha kwambiri. Chophimbacho chimakhala ndi ubwino wa ntchito yosavuta yopaka, palibe kuipitsidwa, kukhudzidwa kwabwino ndi kukana kupindika komanso kutentha kwakukulu.
1)Malinga ndi njira yogwiritsira ntchito, ikhoza kugawidwa kukhala: ufa wopopera mankhwala mkati mwa payipi, ufa wopopera mankhwala kunja kwa payipi ndi ufa wambiri mkati ndi kunja kwa payipi. Ufa womwe umagwiritsidwa ntchito kupopera mbewu mankhwalawa kunja kwa payipi umagawidwa kukhala ufa wosanjikiza umodzi, ufa wosanjikiza kawiri ndi mawonekedwe atatu osanjikiza odana ndi dzimbiri ufa.
2) Malinga ndi cholinga, akhoza kugawidwa mu: ufa payipi mafuta ndi gasi, ufa payipi madzi akumwa, ufa payipi moto, ufa odana malo amodzi mpweya wabwino payipi mu mgodi malasha, ufa payipi mankhwala, ufa pobowola chitoliro. , ufa wopangira zitoliro, ufa wa payipi ya sitima yapamadzi, ufa wamadzi amchere ambiri oletsa kuwononga, etc.
3)Malinga ndi machiritso, amatha kugawidwa m'mitundu iwiri: kuchiritsa mwachangu komanso kuchiritsa wamba. Machiritso a ufa wochiritsa mwachangu nthawi zambiri amakhala 230 ℃ / 0.5 ~ 2min. Amagwiritsidwa ntchito kwambiri kupopera mbewu mankhwalawa kunja kwa payipi kapena mawonekedwe atatu osanjikiza odana ndi dzimbiri. Chifukwa cha nthawi yaifupi yochiritsa komanso kuchita bwino kwambiri, ndikoyenera kugwira ntchito pamzere wa msonkhano; Machiritso a ufa wamba wochiritsa nthawi zambiri amakhala wopitilira 230 ℃ / 5min. Chifukwa cha nthawi yayitali yochiritsa komanso kuyanika bwino, ndikoyenera kupopera mbewu mankhwalawa mu payipi.
Makamaka monga: electrostatic kupopera mbewu mankhwalawa njira, matenthedwe kupopera mbewu mankhwalawa njira, kuyamwa njira, fluidized bedi njira, mpukutu ❖ kuyanika njira, etc. Mikangano electrostatic kupopera mbewu mankhwalawa njira, kuyamwa njira kapena matenthedwe kupopera mbewu mankhwalawa njira zambiri ntchito payipi mkati ❖ kuyanika; Njira zopopera mbewuzi zimakhala ndi chinthu chodziwika bwino, ndiye kuti, musanapondereze, chogwiriracho chiyenera kutenthedwa mpaka kutentha kwina kusungunula ufawo ukangolumikizana. Kutentha kwa zinyalala kuyenera kupangitsa kuti filimuyo ipitirire kuyenda komanso kupitilira mulingo ndikuphimba chitoliro chonse chachitsulo, makamaka pakukhumudwa kwa chitoliro chachitsulo ndi mbali zonse ziwiri za weld, ndipo utoto wosungunuka umalowa ndikudzaza kuti upangire zokutira. ophatikizana kwambiri ndi chitoliro chachitsulo, Chepetsani pores ndikuchiza mkati mwa nthawi yodziwika. Pomaliza, kuziziritsa ndi madzi kuti athetse kuchiritsa.
