Baaxadda codsiga
Ku habboon daaweynta ka hortagga daxalka ee dhinaca gudaha ee qiiqa.Nooca I wuxuu ku habboon yahay daaweynta ka-hortagga daxalka ee dusha si toos ah ula xiriirto gaasta qiiqa, oo leh xadka u adkeysiga kulaylka ee 250 ℃ iyo 40% adkeysiga sulfuric acid.
Tilmaamaha Codsiga
Daawaynta substrate-ka iyo dusha sare ee lagu dabaqi karo
1, Daawaynta substrate-ka birta: bacaadka ama rasaasta qarxinta si looga saaro miridhku ilaa heerka Sa2.5, qallafsanaanta 40 ~ 70um, si kor loogu qaado adhesion ee daahan iyo substrate ka.
2. Markaad isticmaalayso, walaaq qaybta A marka hore, ka dibna ku dar qaybta daaweynta ee B si siman, walaaq si siman, u ilaali wakhtiga soo-gelinta 15 ~ 30 daqiiqo, ku hagaaji viscosity codsigaqaddarka ku habboonkhafiif ah oo gaar ah si waafaqsan hababka codsiga.
Hababka codsiga
1, buufinta aan hawada lahayn, buufinta hawada ama rullaluistemadka
Dahaarka buraash iyo rullaluistu waxay kaliya lagula talinayaa jaakad xariijimo ah, daahan meel yar ama taabasho.
2, Lagu taliyay dhumucda filimka qalalan: 300um, lakabka kaliya ee daahan wuxuu ku saabsan yahay 100um.
3, Marka la eego in deegaanka daxalka ahi uu aad u adag yahay, dahaarka maqanna ay sababi doonto in birta ay si dhakhso ah u daxaloobaan, waxay yaraynaysaa nolosha adeegga.
iyada oo ay ugu wacan tahay isticmaalka jawiga daxalka ah ee filimka dahaarka ah oo aad u xoog badan, daadinta ayaa ka dhigi doonta dahaarka si degdeg ah oo hoos u dhigaya nolosha adeegga.

Daaweynta dusha sare
Saliida ama dufanka waa in laga saaraa si waafaqsan heerka nadiifinta dareeraha SSPC-SP-1.
Waxaa lagu talinayaa in lagu buufiyo daweynta dusha birta ilaa Sa21/2 (ISO8501-1: 2007) ama heerka SSPC-SP10.
Haddii oksaydhisku ku dhaco dusha sare ka dib buufinta iyo ka hor rinjiyeynta alaabtan, ka dibna dusha sare waa in dib loo jetted.La kulan heerarka muuqaalka ee la cayimay.Cilladaha dusha sare ee soo baxa inta lagu jiro daawaynta buufinta waa in la miiriyaa, la buuxiyaa, ama si habboon loo daaweeyaa.Qalafsanaanta dusha lagu taliyey waa 40 ilaa 70μm.Substrates-ka lagu daweeyay ciid-qarxinta ama rasaasta qaraxda waa in lagu nadiifiyaa 4 saacadood gudahood.
Haddii substrate-ka aan lagu daweynin heerka loo baahan yahay, waxay keeni doontaa soo noqoshada miridhku, filimka rinjiga, cilladaha filimka rinjiga inta lagu jiro dhismaha, iwm.
Tilmaanta codsiga
Isku darka: Alaabta waxaa lagu baakadeeyay laba qaybood, Kooxda A iyo Kooxda B. Saamigu waa sida waafaqsan qeexida alaabta ama calaamadda foosto baakadaha.Marka hore si fiican ugu qas qaybta A ee qasiyaha korontada, ka dibna ku dar qaybta B si siman oo walaaq.Ku dar qadar ku habboon oo khafiif ah epoxy, saamiga milanka ee 5 ~ 20%.
Ka dib marka rinjiga la isku daro oo si fiican loo walaaqo, ha u bislaadeen 10 ~ 20 daqiiqo ka hor codsiga.Waqtiga bislaada iyo muddada lagu dabaqi karo waa la soo gaabin doonaa marka heerkulku kor u kaco.Rinjiga la habeeyey waa in la isticmaalaa gudaha muddada ansaxinta.Rinjiga ka sarreeya xilliga lagu dabaqi karo waa in lagu tuuraa qashinka oo waa inaan mar dambe la isticmaalin.

Hababka codsiga
Ku buufinta hawada la'aanta ayaa lagula talinayaa dhismaha aag weyn, buufinta hawada, buraashka ama dahaarka rullaluistemadka sidoo kale waa la isticmaali karaa.Haddii buufinta la isticmaalo, tolida alxanka iyo geesaha waa in hore loo rinjiyeeyaa, haddii kale, waxay keeni doontaa qoynta liidata ee rinjiga substrate-ka, daadinta, ama filimka rinjiga khafiifka ah, taasoo keenta miridhku iyo diirka filimka rinjiga.
Hakad ku jiro hawsha: rinjiga ha kaga tagin tubooyinka, qoryaha, ama qalabka wax lagu buufiyo.Ku nadiifi dhammaan qalabka si fiican oo khafiif ah.Rinjiga waa in aan dib loo xirin ka dib marka la isku daro.Haddii shaqada ay hakad ku jirto muddo dheer, waxaa lagu talinayaa in la isticmaalo rinji cusub oo isku dhafan marka dib loo bilaabo shaqada.
Ka taxadaritaan
Alaabtani waa dahaarka khaaska ah ee ka-hortagga daxalka ee gidaarka gudaha ee desulfurization iyo qalabka denitrification, dusha hoose waa hal nooc, oo leh caabbinta abrasion sare, caabbinta acid wanaagsan (40% sulfuric acid), iyo iska caabbinta heerkulka wanaagsan.Inta lagu jiro dhismaha, waa in aan la isku qasin qoriga buufinta, baaldiga rinjiga, buraashka rinjiga, iyo rollerka, iyo walxaha lagu rinjiyeeyay alaabtan waa in aan lagu wasakhayn rinjiyada kale ee caadiga ah.
Kormeerka filimka daahan
a.Burushka, duubka, ama buufinta waa in si siman loo mariyaa, iyada oo aan wax dareerin ah lahayn.
b.Hubinta dhumucda: ka dib lakab kasta oo rinji ah, hubi dhumucda, ka dib oo dhan rinji waa in la fiiriyaa wadarta dhumucda filimka rinjiga, lagu qiyaaso dhibcood sida waafaqsan 15 kasta oo mitir oo laba jibbaaran, 90% (ama 80%) dhibcood la qiyaasay ayaa loo baahan yahay si ay u gaadho qiimaha dhumucda la cayimay, dhumucda aan gaadhin qiimaha la cayimay waa in aanu ka hoosayn 90% (ama 80%) qiimaha la cayimay, hadii kale waa in rinji dib loo rinjiyeeyaa.
c.Dhumucda guud ee dahaarka iyo tirada kanaalka dahaarka waa inay buuxiyaan shuruudaha naqshadeynta;dusha sare waa inuu ahaadaa mid siman oo aan lahayn calaamado, midab joogto ah, aan lahayn dalool, goobooyin, hoos u qulqulaya, iyo jajab.
d.Kormeerka muuqaalka: Ka dib dhismo kasta oo rinji ah, muuqaalka waa in la fiiriyaa, lagu fiiriyaa indhaha qaawan ama 5 jeer muraayad weyneynaya, iyo godad, dildilaac, diiray, iyo daadinta rinjiga waa in la hagaajiyaa ama dib loo rinjiyeeyaa, qadar yar oo qulqulka ah ayaa laalaada. loo ogol yahay inuu jiro.Shuruudaha gaarka ah ee tayada daahan waa sida soo socota:
| Alaabta kormeerka | Shuruudaha tayada | Hababka kormeerka |
| Diil, daadinta burushka, miridhku digsiga, iyo galinta hoose | Lama ogola | Kormeer muuqaal ah |
| Pinhole | Lama ogola | 5 ~ 10x weynaynta |
| Soconaya, maqaarka laalaabtay | Lama ogola | Kormeer muuqaal ah |
| Dhumucda filimka qalajinta | Aan ka yarayn dhumucda naqshadeynta | Cabiraadaha Dhumucda Birlabka |
Shuruudaha codsiga iyo xannibaadaha
Heerkulka deegaanka iyo substrate-ka:5-40 ℃;
Nuxurka biyaha ee substrate:<4%<br />Qoyaanka hawada ee ku habboon:Qoyaanka qaraabada ah ilaa 80%, roobka, ceeryaamo, iyo maalmaha barafka lama dhisi karo.
barta sayaxa:Heerkulka dusha sare ee substrate-ka ayaa ka sarreeya 3 ℃ barta sayaxa.
Haddii lagu dhiso deegaan aan buuxin shuruudaha dhismaha, dahaarka ayaa isku ururin doona oo ka dhigaya filimka rinjiga ubaxa, finan, iyo cillado kale.
Alaabtani maaha mid u adkaysata iftiinka ultraviolet, sidaas darteed waxaa lagula talinayaa jawiga gudaha.
Taxadarrada badbaadada
Alaabtan waa in lagu isticmaalo goobta wax soo saarka ee xirfadlayaasha rinjiyeynta ee hoos yimaada buug-gacmeedkan, xaashida xogta badbaadada alaabta, iyo tilmaamaha weelka baakadaha.Haddii xaashidan Badbaadada Qalabka (MSDS) aan la akhriyin;alaabtan waa in aan la isticmaalin.
Dhammaan dahaarka iyo isticmaalka alaabtan waa in lagu sameeyaa dhammaan caafimaadka qaranka, badbaadada, iyo heerarka deegaanka iyo xeerarka.
Haddii alxanka ama goynta ololka lagu samaynayo birta lagu dahaadhay alaabtan, boodhka ayaa soo baxaya, sidaas darteed qalab ilaalin shakhsi ah oo ku habboon iyo hawo soosaar deegaan oo ku filan ayaa loo baahan yahay.
Kaydinta
Waxa lagu kaydin karaa ugu yaraan 12 bilood heerkul ah 25°C.
Intaa ka dib waa in mar kale la hubiyaa ka hor inta aan la isticmaalin.Ku kaydi meel qalalan, meel hadh leh, oo ka fog kulaylka iyo ilaha dabka.
Bayaanka
Macluumaadka lagu bixiyey buug-gacmeedkan waxay ku salaysan yihiin shaybaadhkayaga iyo waayo-aragnimada wax-ku-oolka ah waxaana loogu talagalay inay tixraac u noqoto macaamiisheena.Maadaama shuruudaha isticmaalka badeecada ay ka baxsan yihiin xakamayntayada, waxaan kaliya siinaa dammaanad tayada alaabta lafteeda.
