Wararka - Waa maxay farqiga u dhexeeya rinjiga u adkaysta miridhku? Waa maxay horumarka mustaqbalka ee daahan ka-hortagga miridhku?

Rinjiga ka hortagga miridhku

Rinjiga ka hortagga miridhku waa nooc ka mid ah walaxda ka ciyaara doorka ka hortagga miridhku, waxay ka hortagtaa daxalka birta waxayna wanaajisaa saameynta ilaalinta filimka rinjiga ee dusha birta. Doorka rinjiga ka-hortagga miridhku waxa loo qaybin karaa laba qaybood: ka-hortagga miridhku jirka iyo kiimikaad-ka-hortagga miridhku, kuwaas oo rinjiga ka-hortagga-daxalka ee kiimikaad loo qaybin karaa xakamaynta daxalka iyo fal-celinta elektiroonigga ah nooca labaad. Walxaha ka ciyaara doorka ka hortagga miridhku inta badan waxaa ka mid ah budada casaanka cas, budada cas ee birta, budada titanium-ka isku dhafan, aluminium tripolyphosphate budada zinc iyo wixii la mid ah. Waqtigan xaadirka ah, rinjiga ka hortagga daxalka ayaa inta badan loo adeegsadaa dahaarka ka-hortagga daxalka, iyo qiimaha dahaadhka ka-hortagga daxalka ayaa ah 6%-8.5%.

Waa maxay faraqa u dhexeeya rinjiga ka hortagga miridhku?

Rinjiga Antirust waa nooc ka mid ah rinjiga ka ilaalin kara sagxadaha birta ee kiimikaad ama korantada hawada, biyaha badda, iwm

Rinjiyeyaashu waa daahan kiimiko ah oo isku dhafan oo si adag u daboolaya dusha sare ee walxaha, ilaaliya, qurxiyaa, calaamadaha iyo ujeedooyinka kale ee gaarka ah, oo sameeya filim adag oo si adag ugu dheggan dusha walxaha oo leh awood gaar ah iyo sii socosho.

1. Shaqooyin kala duwan:

Rinjiga ka-hortagga miridhku wuxuu leeyahay sifooyinka ka-hortagga daxalka iyo ka-hortagga miridhku, filimku waa mid adag, waxqabad aad u fiican, iyo adkaanta ayaa ka sarreeya rinjiga caadiga ah. Rinjiga caadiga ah ma laha shaqo lid ku ah miridhku, sababtoo ah walxaha filimka caadiga ah ee rinjiga waa alkyd resin, iyada oo loo marayo oksaydhka iyo qalajinta, qallafsanaanta liidata, farqiga darajada adhesion.

2. Nolosha adeeg ee kala duwan:

Rinjiga ka-hortagga miridhku waxa loo isticmaali karaa 5-8 sano haddii ay dhacdo isku mid ah. Rinjiga caadiga ah waxaa badanaa lagu isticmaalaa dibadda ilaa 3 sano. Laba ama saddex sano ka dib, way fududahay in la dhaco, baaba'o oo budo.

3. Noocyo kala duwan:

Rinjiga ka-hortagga miridhku: Rinjiga phenolic-ka-hortagga miridhka, rinjiga alkyd-ka-hortagga miridhku (casaanta birta, cawl, ledhka cas), rinjiga caag ka-hortagga miridhku koloriinated, rinjiga epoxy-ka-hortagga miridhku (Rinjiga zinc phosphate anti-rust rinjiga, jannada casaanka ah rinjiga ka-hortagga miridhku, rinjiga zinc qani ah ka-hortagga miridhku, rinjiga cas cas anti- miridhku), iwm

Rinjiga: Rinjiga noocyada hodanka ah, rinjiga ka hortagga miridhku sidoo kale waa nooc ka mid ah rinjiga, ka sokow rinjiga waxaa sidoo kale ka mid ah rinjiga alwaax, rinjiga sagxada, rinjiga derbiga dibadda, rinjiga dhagaxa, rinjiga midabada badan, rinjiga aluminiumka, rinjiga dabka, rinjiga cinjirka iyo wixii la mid ah.

Siddeed tilmaamood oo loogu talagalay horumarinta mustaqbalka ee rinjiga ka hortagga miridhku

Ugu horreyntii, horumarinta biyaha-ku-salaysan ee ka hortagga-xakamaynta iyo rinjiga sare ee qaababka birta.

Biyo-ku-salaysan-soo-baxa ka-hortagga miridhku waa inuu xalliyaa niyad-jabka substrate "daxalka flash" iyo iska caabbinta biyaha liidata, iyo kor u kaca qaar ka mid ah emulsions-ka-free emulsions cusub ayaa asal ahaan wanaajiyey horyaalka caabbinta biyaha liidata, iyo mustaqbalka waa in diiradda la saaro xallinta dhibaatooyinka shaqada dhismaha iyo shaqada codsiga. Sida jaakad sare, waxay inta badan tahay in la hagaajiyo qurxinta iyo adkeysiga iyada oo la raacayo xaaladda hubinta shaqada ilaalinta.

Midda labaad waa in la horumariyo taxane ah oo ka kooban maaddo adag iyo rinjiga ka hortagga miridhku-ka ee aan dareeraha lahayn.

Qodista, meelaha xeebaha ah iyo mashaariicda baaxadda weyn ee ka hortagga miridhku ee shaqada ka hortagga miridhku aadka u raagaya ee shuruudaha daaha ayaa ah mid degdeg ah, suuqa hadda jira asal ahaan waa shirkado shisheeye oo ay leeyihiin alaabooyinka la soo dejiyo. Badeecadaha Shiinaha ayaa inta badan ku jira heerka farsamada, xoogga dhaqaalaha, nidaamka hubinta tayada iyo sumcadda badeecada iyo farqiga kale ee xoogga leh ee wadamada shisheeye, way adagtahay in la galo suuqa. Si taas loo gaaro, ugu horreyntii, dadaallada waa in lagu sameeyaa horumarinta farsamada, gaar ahaan horumarinta macdanta macdanta "lead-free" iyo chromium-free anti- miridhku, taas oo ku salaysan zinc phosphate iyo aluminium tripolyphosphate primer anti- miridhku.

Midda saddexaad waa in la horumariyo curiyaha zinc-ku-salaysan ee biyaha ku salaysan.

Soosaarayaasha zinc-ka hodanka ku ah ee aan organic-ga ahayn iyo tifaftiraha zinc-ka-salaysan ee biyaha-ku-salaysan waa mid ka mid ah curiyeyaasha muddada-dheer shaqeynaya, laakiin waxay yihiin dahaarka dareeraha ah. Biyo-ku-salaysan biyo-ku-salaysan-soo-saare-soo-saarka zinc-hodanka leh oo leh modules-ka potassium silicate oo sarreeya maaddaama maadada saldhigga ahi ay tahay daahan ka-hortagga miridhku shaqaynayo oo sarreeya oo lagu tijaabiyey ku-dhaqan ahaan waxayna leedahay karti horumarineed.

Midda afraad waa horumarinta kulaylka ku beddelashada dahaarka kulaylka u adkaysta dahaarka.

Kuleyliyeyaasha kuleylku waxay u baahan yihiin daahan ka-hortagga miridhku leh kulaylka sarreeya iyo kuleylka kuleylka, daahanka epoxy amino ee hadda la isticmaalo wuxuu u baahan yahay in lagu daaweeyo 120 ° C wuxuuna u baahan yahay dahaar badan, oo aan loo isticmaali karin aaladaha waaweyn.

Midda shanaad waa in la sameeyo dahaar lagu daweyn karo heerkulka qolka oo ay fududahay in la mariyo.

Qodobka ugu muhiimsan waa in la helo dheelitirka ugu fiican ee u dhexeeya shaqada ka hortagga miridhku, shaqada wareejinta kulaylka iyo shaqada dhismaha ee daahan.

Midda lixaad waa horumarinta daahan flake anti- miridhku.

Mica iron oxide (MIO) waxay leedahay iska caabin dielectric heer sare ah, iska caabin gabowga atmospheric iyo shaqada xannibi, oo waxaa si ballaaran loo isticmaalaa sida aasaasiga ah iyo rinjiga sare ee Galbeedka Yurub.

Toddobaad, horumarinta taxane caag ah oo koloriin ah oo beddelka daahan ka-hortagga miridhku.

Sababtoo ah caag chlorinated waa hal qayb, dhismuhu waa sahlan yahay, caabbinta biyaha, caabbinta saliidda, caabbinta duqnimada atmospheric waa mid aad u fiican, oo si ballaaran loo isticmaalo dhismaha maraakiibta, ka hortagga miridhku warshadaha iyo beeraha kale, waxaa jira suuq ballaadhan oo Shiinaha ah. Si kastaba ha ahaatee, sababtoo ah soosaarka caag koloriin leh ayaa CC1 u isticmaala dareere ahaan, lakabka ozone waa la burburiyaa.

Midda siddeedaad waa horumarinta walxaha ka hortagga miridhku ka kooban yahay ee organic modified.

Sanadihii la soo dhaafay, codsiga emulsion organic la taaban karo wax laga beddelay si loo hagaajiyo xooggeeda, iska caabin dhexdhexaad ah, oo si ballaaran loo isticmaalo daahan dabaqa warshadaha. Waxaa ka mid ah, emulsion water emulsion (ama epoxy-ku salaysan dareeraha) ayaa ugu dhaqsaha badan, kaas oo loo yaqaan sibidhka polymer.
