Kuponyedwa kwachitsulo chitoliro epoxy utomoni kumafunika kufikira maola 350 a mayeso opopera mchere pansi pa muyezo wa EN877, makamakaChitoliro cha DS sml chimatha kufikira maola 1500 amcheremayeso(analandira chiphaso cha Hong Kong CASTCO mu 2025). Yalangizidwa kuti igwiritsidwe ntchito m'malo achinyezi ndi mvula, makamaka m'mphepete mwa nyanja, zokutira za epoxy resin pa chishango chakunja cha DS SML chitoliro chimapereka chitetezo chabwino kwa chitoliro. Pogwiritsa ntchito kuwonjezereka kwa mankhwala apakhomo monga ma organic acid ndi caustic soda, zokutira za epoxy ndizotchinga bwino kwambiri polimbana ndi zinthu zosokoneza, komanso kupanga mapaipi osalala kuti asatseke dothi. Zotsutsana ndi dzimbiri za mapaipi achitsulo otayidwa zimapangitsa kuti zigwiritsidwe ntchito kwambiri m'ma laboratories, zipatala, mafakitale ndi nyumba zogona padziko lonse lapansi.
Komabe, ngati utotowo sunasungidwe bwino, ukhoza kupangitsa kuti chitoliro chachitsulo chikhale chopepuka kapena kusinthika pambuyo pojambula, zomwe zimakhudza mawonekedwe ndi chitetezo cha mankhwalawa.
1. Njira yoyenera yosungiramo utoto wa A1 epoxy
Utoto wa A1 epoxy ndi chophimba choteteza kwambiri, ndipo mikhalidwe yake yosungira imakhudza mwachindunji kukhazikika kwa zokutira ndi kuyanika kwake. Njira yoyenera yosungira ili ndi izi:
1. Kuwongolera kutentha
Kutentha koyenera: Utoto wa A1 epoxy uyenera kusungidwa m'malo a 5 ℃ ~ 30 ℃ kupewa kutentha kwambiri kapena kutsika komwe kumakhudza kukhazikika kwa utoto.
Pewani kutentha kwambiri:Kutentha kwambiri (> 35 ℃) kumapangitsa kuti zosungunulira mu utoto zisamasefuke mwachangu, ndipo gawo la utomoni limatha kuchitidwa ndi polymerization, zomwe zimawonjezera kukhuthala kwa utoto kapena kulepheretsa kuchiritsa.
Kutentha kochepa (<0 ℃) kungapangitse kuti zinthu zina mu utotowo zisungunuke kapena kupatukana, zomwe zimapangitsa kuti kumamatira kumachepa kapena mtundu wosiyana ukapenta.
2. Kusamalira chinyezi
Malo ouma: Chinyezi chapakati pa malo osungiramo chiyenera kuyendetsedwa pakati pa 50% ndi 70% kuteteza mpweya wonyowa kulowa mu ndowa ya penti.
Osindikizidwa komanso osatetezedwa ndi chinyezi: Chidebe cha penti chiyenera kutsekedwa mwamphamvu kuti chinyontho chisalowe, apo ayi chikhoza kuyambitsa stratification, agglomeration kapena kuchiritsa kwachilendo.
3. Kusungira kutali ndi kuwala
Pewani kuwala kwa dzuwa: Kuwala kwa Ultraviolet kumathandizira kukalamba kwa utomoni wa epoxy, zomwe zimapangitsa kusintha kwa utoto kapena kuwonongeka kwa magwiridwe antchito. Choncho, utotowo uyenera kusungidwa m’nyumba yosungiramo zinthu zoziziritsa kukhosi, zosaoneka ndi kuwala.
Gwiritsani ntchito zotengera zakuda: Utoto wina wa A1 epoxy amapakidwa mumitundu yakuda kuti muchepetse kukhudzidwa kwa maso. Choyikapo choyambirira chiyenera kusungidwa bwino panthawi yosungira.
4. Pewani kuyimirira kwa nthawi yayitali
Tembenuzani nthawi zonse: Ngati utoto wasungidwa kwa nthawi yayitali (kupitirira miyezi isanu ndi umodzi), chidebe cha penti chiyenera kutembenuzidwa kapena kukulungidwa nthawi zonse kuti pigment ndi utomoni zisakhazikike ndi stratifying.
Mfundo Yoyamba Yoyamba: Gwiritsani ntchito potengera tsiku lopangira kuti penti isalephereke chifukwa chatha.
5. Pewani kuipitsidwa ndi mankhwala
Sungani padera: Utoto uyenera kusungidwa kutali ndi mankhwala monga zidulo, alkalis, ndi zosungunulira za organic kupeŵa kusintha kwa mankhwala komwe kumayambitsa kuwonongeka.
Mpweya wabwino: Malo osungiramo ayenera kukhala ndi mpweya wabwino kuti ateteze kuchulukidwa kwa zinthu zosasunthika zomwe zimakhudza mtundu wa utoto.
Zotsatirazi ndi zithunzi zonyamula za SML Pipe & zoyikira mu nyumba yosungiramo zinthu za DINSEN:
2. Kusanthula zomwe zimayambitsa chitoliro chachitsulo chonyezimira kapena kusinthika
Ngati utoto wa epoxy wa A1 sunasungidwe bwino, chitoliro chachitsulo chotayidwa pambuyo popenta chikhoza kukhala ndi mavuto monga kuwala, chikasu, kuyera, kapena kusinthika pang'ono. Zifukwa zazikulu ndi izi:
1. Kutentha kwakukulu kumayambitsa kukalamba kwa utomoni
Chodabwitsa: Mtundu wa utoto umasanduka wachikasu kapena mdima pambuyo pojambula.
Chifukwa: Pamalo otentha kwambiri, utomoni wa epoxy ukhoza kutulutsa okosijeni kapena kulumikizana, zomwe zimapangitsa kuti utoto usinthe. Pambuyo kupenta, utoto pamwamba pa chitoliro chachitsulo choponyedwa chikhoza kutaya mtundu wake woyambirira chifukwa cha utomoni wokalamba.
2. Kulowerera kwa chinyontho kumabweretsa kuchiritsa kwachilendo
Chodabwitsa: Chifunga choyera, choyera kapena chosiyana chimawonekera pamwamba pa zokutira.
Chifukwa: Mtsuko wa penti sumatsekedwa mwamphamvu panthawi yosungira. Chinyezi chikalowa, chimakhudzidwa ndi mankhwalawo kuti apange mchere wa amine kapena carbon dioxide, zomwe zimapangitsa kuti pakhale vuto la chifunga pamwamba pa zokutira, zomwe zimakhudza kuwala kwachitsulo kwa chitoliro chachitsulo.
3. Photodegradation chifukwa cha cheza ultraviolet
Chodabwitsa: Mtundu wa utoto umakhala wopepuka kapena kusiyana kwamitundu kumachitika.
Choyambitsa: Kuwala kwa ultraviolet padzuwa kumawononga pigment ndi utomoni mu utoto, zomwe zimapangitsa kuti utoto wapaipi yachitsulo ikapenta uzizirala kapena kusinthika.
4. Kusungunuka kwa zosungunulira kapena kuipitsidwa
Chodabwitsa: Tinthu tating'onoting'ono, tinthu tating'onoting'ono tambiri tambiri tambiri tambiri tating'onoting'ono kapena kusinthika kwamtundu kumawonekera pafilimu ya utoto.
Chifukwa: Kuchuluka kwa zosungunulira zosungunulira kumapangitsa kukhuthala kwa utoto kukhala kokwera kwambiri, ndipo kutsika kwa atomization pakupopera mbewu kumadzetsa mtundu wosiyana.
Zonyansa (monga fumbi ndi mafuta) zosakanikirana panthawi yosungiramo zidzakhudza mapangidwe a filimu ya utoto ndikuyambitsa zolakwika pamwamba pa chitoliro chachitsulo.
3. Momwe mungapewere mtundu wachilendo wa chitoliro chachitsulo pambuyo pojambula
Tsatirani mosamalitsa zosungirako ndikuonetsetsa kuti kutentha, chinyezi, chitetezo cha kuwala, ndi zina zotero.Kusungidwa kolakwika kwa chitoliro chachitsulo chokhala ndi utoto wa A1 epoxy kungapangitse kuti mtunduwo ukhale wopepuka, wachikasu kapena wotayika. Mwa kuwongolera mosamalitsa kutentha, chinyezi, chitetezo chopepuka ndi zina, ndikuwunika nthawi zonse momwe pt ilili, zolakwika zokutira zomwe zimayambitsidwa ndi zovuta zosungirako zitha kupewedwa bwino, kuwonetsetsa kuti kukongola ndi chitetezo cha chitoliro chachitsulo choponyedwa chili bwino kwambiri.
