Wararka - Waa maxay faraqa u dhexeeya rinjiga u adkaysta miridhku iyo rinjiga? Waa maxay horumarka mustaqbalka ee dahaarka ka hortagga miridhku?

Rinjiga ka hortagga miridhku

Rinjiga ka hortagga miridhku waa nooc ka mid ah walaxda ciyaarta doorka ka hortagga miridhku, wuxuu ka hortagaa miridhku birta, wuxuuna hagaajiyaa saameynta ilaalinta ee filimka rinjiga ee dusha birta. Doorka rinjiga ka hortagga miridhku waxa loo qaybin karaa laba qaybood: mid jireed oo ka hortagga miridhku iyo mid kiimiko ah oo ka hortagga miridhku, kuwaas oo rinjiga kiimikada ee ka hortagga miridhku loo qaybin karo mid ka hortagga miridhku iyo mid ka hortagga electrochemical nooca labaad. Walxaha ciyaara doorka ka hortagga miridhku waxay inta badan ka kooban yihiin budada casaanka cas, budada birta cas, budada titanium ee isku dhafan, budada zinc ee aluminium tripolyphosphate iyo wixii la mid ah. Waqtigan xaadirka ah, rinjiga ka hortagga miridhku waxa inta badan loo isticmaalaa dahaarka ka hortagga miridhku, qiimaha dahaarka ka hortagga miridhku wuxuu ka dhigan yahay 6%-8.5%.

Waa maxay faraqa u dhexeeya rinjiga ka hortagga miridhku iyo rinjiga?

Rinjiga ka hortagga miridhku waa nooc rinji ah oo ka ilaalin kara dusha sare ee birta daxalka kiimikada ama elektrokemikaalka ee jawiga, biyaha badda, iwm. Rinjiga jirka iyo kiimikada ka hortagga miridhku, sida casaanka birta, budada aluminiumka, rinjiga graphite ka hortagga miridhku, rasaasta cas, rinjiga zinc ee jaalaha ah ee ka hortagga miridhku iyo wixii la mid ah.

Rinjigu waa dahaar kiimiko ah oo si adag u daboolaya dusha sare ee walxaha, ilaaliya, qurxiya, calaamadaha iyo ujeedooyin kale oo gaar ah, wuxuuna sameeyaa filim adag oo si adag ugu dheggan dusha sare ee walxaha oo leh xoog iyo joogto gaar ah.

1. Shaqooyin kala duwan:

Rinjiga ka hortagga miridhku wuxuu leeyahay sifooyin ka hortagga miridhku iyo miridhku, filimku waa mid adag, waxqabad aad u fiican, adkaantana way ka sarreysaa tan rinjiga caadiga ah. Rinjiga caadiga ah ma laha shaqo ka hortagga miridhku, sababtoo ah walxaha rinjiga ee caadiga ah waa resin alkyd ah, iyada oo loo marayo oksaydheynta iyo qalajinta, adkaanta liidata, farqiga heerka isku dhejinta.

2. Nolosha adeeg ee kala duwan:

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

3. Noocyo kala duwan:

Rinjiga ka hortagga miridhku: rinjiga phenolic ka hortagga miridhku, rinjiga alkyd ka hortagga miridhku (casaanka birta, cawlka, rasaasta cas), rinjiga caagga ah ee koloriin ku jira oo ka hortagga miridhku, rinjiga epoxy ka hortagga miridhku (rinjiga zinc phosphate ka hortagga miridhku, rinjiga cas ee ka hortagga miridhku, rinjiga zinc ka hortagga miridhku ku badan yahay, rinjiga cas ee ka hortagga miridhku ku badan yahay birta), iwm.

Rinjiga: Noocyo badan oo rinji ah, rinji ka hortagga miridhku sidoo kale waa nooc rinji ah, marka laga soo tago rinjiga waxaa ku jira rinji alwaax ah, rinji dabaq ah, rinji derbi dibadda ah, rinji dhagax ah, rinji midabyo badan leh, rinji aluminium ah, rinji dab-damis ah, rinji latex ah iwm.

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

Marka hore, horumarinta rinjiga ka hortagga miridhku ku salaysan yahay biyaha iyo rinjiga sare ee dhismayaasha birta ah.

Biyo-sameeyaha ka hortagga miridhku waa inuu xalliyaa niyad-jabka "mirdhuhu" ee substrate-ka iyo iska caabbinta biyaha oo liidata, iyo kororka qaar ka mid ah emulsions-ka cusub ee aan lahayn emulsifier-ka ayaa si aasaasi ah u hagaajiyay cinwaankiisa iska caabbinta biyaha oo liita, mustaqbalkuna waa inuu diiradda saaraa xallinta dhibaatooyinka shaqada dhismaha iyo shaqada codsiga. Sida jaakad sare, waxay inta badan tahay inay hagaajiso qurxinteeda iyo waaritaankeeda iyadoo la hubinayo shaqada ilaalinta.

Tan labaad waa in la sameeyo taxane ah rinji adag oo heer sare ah iyo rinji ka hortagga miridhku aanu milmin.

Qodista, goobaha badda iyo mashaariicda waaweyn ee ka hortagga miridhku ee shaqada aadka u waara ee ka hortagga miridhku ee shuruudaha dahaarka waa kuwo aad u degdeg ah, suuqa hadda jira asal ahaan waa shirkado ay leeyihiin ajaanib iyo alaabada la soo dejiyo ee la haysto. Badeecadaha Shiinaha waxay inta badan ku jiraan heerka farsamada, xoogga dhaqaale, nidaamka hubinta tayada iyo sumcadda badeecada iyo farqiga kale ee xoogga oo dhammaystiran oo ay la leeyihiin waddamada shisheeye, way adag tahay in suuqa la galo. Si taas loo gaaro, marka hore, waa in la sameeyaa dadaallo ku aaddan horumarinta farsamada, gaar ahaan horumarinta rinjiga aan rasaasta lahayn iyo kan aan chromium lahayn, taas oo ah, iyadoo lagu saleynayo zinc phosphate iyo aluminium tripolyphosphate ka hortagga miridhku.

Tan saddexaad waa in la sameeyo rinji-sameeye biyo ku salaysan oo zinc-ku hodan ku yahay.

Biyo-sameeyaha zinc-ka hodanka ku ah iyo biyo-sameeyaha zinc-ka hodanka ku ah waa mid ka mid ah biyo-sameeyayaasha muddada dheer shaqeeya, laakiin waa dahaadh ku salaysan dareeraha. Biyo-sameeyaha zinc-ka hodanka ku ah biyaha oo leh modulus potassium silicate sare oo ah walxaha aasaasiga ah waa dahaar sare oo ka hortagga miridhku shaqeeyo oo lagu tijaabiyay ku dhaqanka wuxuuna leeyahay awood horumarineed.

Tan afraad waa horumarinta qalabka kulaylka lagu beddelo ee dahaadha dahaarka ka hortagga miridhku.

Beddelayaasha kulaylka waxay u baahan yihiin dahaadh ka hortagga miridhku oo leh iska caabin kulaylka sare iyo kontoroolka kulaylka, dahaarka amino-ka epoxy-ga ee hadda la isticmaalo wuxuu u baahan yahay in lagu bogsado heerkul ah 120 ° C wuxuuna u baahan yahay dahaar badan, kaas oo aan loo isticmaali karin aaladaha waaweyn.

Tan shanaad waa in la sameeyo dahaar lagu bogsan karo heerkulka qolka oo si fudud loo mari karo.

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

Tan lixaad waa horumarinta dahaarka ka hortagga miridhku.

Mica iron oxide (MIO) waxay leedahay iska caabin dielectric oo aad u fiican, iska caabin gabowga jawiga iyo shaqo xannibaad ah, waxaana si weyn loogu isticmaalaa rinjiyeynta rinjiga iyo dusha sare ee Galbeedka Yurub.

Toddobaad, horumarinta taxane caag ah oo koloriin lagu daray oo ah beddelka dahaarka ka hortagga miridhku.

Maadaama caagga koloriin lagu dahaadhay uu yahay hal qayb, dhismuhu waa mid fudud, iska caabbinta biyaha, iska caabbinta saliidda, iska caabbinta gabowga jawiga waa mid aad u fiican, si weyn ayaa loogu isticmaalaa dhismaha maraakiibta, ka hortagga miridhku warshadaha iyo beeraha kale, waxaa jira suuq ballaaran oo Shiinaha ah. Si kastaba ha ahaatee, maadaama soo saarista caagga koloriin lagu dahaadhay uu CC1 u isticmaalo dareere ahaan, lakabka ozone-ka waa la burburiyaa.

Tan siddeedaad waa horumarinta agabka ka hortagga miridhku ee aan dabiiciga ahayn ee wax laga beddelay.

Sannadihii ugu dambeeyay, codsiga shubka organic-ga ah ee wax laga beddelay si loo hagaajiyo xooggiisa, iska caabinta dhexdhexaadka ah, oo si weyn loogu isticmaalo dahaarka dabaqa warshadaha. Kuwaas waxaa ka mid ah, emulsion-ka biyaha epoxy (ama epoxy-ga ku salaysan dareeraha) ayaa si dhakhso ah u koraya, kaas oo loo yaqaan sibidhka polymer.
