Rinjiga dhaldhalaalka ah ee alkyd
Marka aan samaynayno naqshadeynta qurxinta guriga, waxaa loo baahan yahay in la tixgeliyo arrimo badan. Mid ka mid ah arrimaha muhiimka ah waa doorashada rinjiga. Waxaa jira shuruudo aad u sarreeya oo ku saabsan nooca, midabka, tayada, iwm. ee rinjiga. Rinjiga alkyd enamel-ka, oo ah nooc cusub oo rinji ah, wuxuu hubaal ahaan soo jiidan doonaa dareenka qof walba.
Dhalaal Alkyd ahwaa rinji dhalaalaya oo aad u hufan oo aad u adag, oo ka kooban resin alkyd ah, midabyo, adkeysi iyo dareereyaal. Dahaarkani wuxuu leeyahay faa'iidooyinka nadiifinta hawada, ka hortagga caaryada, ka hortagga miridhka, ka hortagga biyaha, ka hortagga wasakhda, ka hortagga xoqidda, iyo kala soocidda formaldehyde, iyo kuwo kale.
Shaqada diyaarinta
Halkan, waxaan diiradda saari doonnaa ka hadalka waxqabadka ka hortagga miridhku ee rinjiga dhaldhalaalka alkyd.
Qaybaha dhaldhalaalka alkyd waxaa ka mid ah resin alkyd iyo adkeye.
- Falcelinta kiimikada ee labadan walxood waxay keeni doontaa sameynta dusha sare oo leh shaqo ka hortag miridhku ku jiro filimka rinjiga.
- Ilkaha Alkyd wuxuu leeyahay adkeysi aad u wanaagsan iyo iska caabin daxalka. Adkaanshaha iyo dhegdhegga filimka rinjiga ayaa buuxin kara shuruudaha ka hortagga miridhku ee tayada sare leh.
- Adkaanta sare ee dhaldhalaalka alkyd waxay si wax ku ool ah u iska caabin kartaa xoqidda xoogga dibadda iyo xoqidda, iyadoo ka ilaalinaysa dusha sare ee walxaha salka ah miridhku iyo cimriga dahaarka.
In kasta oo rinjiga alkyd enamel uu leeyahay sifooyin wanaagsan oo ka hortagga miridhku, haddana maaha nooc gaar ah oo dahaarka ka hortagga miridhku. Sidaa darteed, marka la naqshadaynayo qurxinta guriga, qofku waa inuu sameeyaa doorashooyin macquul ah oo ku saabsan nooca iyo nooca dahaarka iyadoo lagu salaynayo xaalado gaar ah. Haddii gurigaagu ku yaal deegaan qoyan ama uu ku yaal dhul xeeb ah, waxaa lagu talinayaa inaad doorato dahaar leh sifooyin ka hortagga miridhku si aad guriga uga ilaaliso khataraha iman kara. Marka la dooranayo dahaarka, qofku waa inuu sidoo kale doortaa dahaarka u dhigma iyadoo lagu salaynayo dabeecadda iyo shuruudaha substrate-ka.
Waxqabadka ka hortagga miridhku ee rinjiga dhaldhalaalka alkyd
Ilkaha Alkyd waa nooc caadi ah oo rinji ah oo leh sifooyin ka hortag miridhku aad u fiican yahay, taasoo ka dhigaysa mid si weyn loogu isticmaalo rinjiga u adkaysta miridhku. Mabda'a ugu weyn ee ka hortagga miridhku ee rinjigan waa in la sameeyo filim ilaalin ah oo dusha sare ah. Filimkani wuxuu si wax ku ool ah uga hortagi karaa qoyaanka, oksijiinta, iyo walxaha daxalka ah inay galaan dusha sare ee birta, taasoo ku gaareysa ujeeddada ka hortagga miridhku. Intaa waxaa dheer, ilkaha alkyd wuxuu sidoo kale leeyahay dhegdheg wanaagsan iyo iska caabin cimilo, wuxuuna ilaalin karaa waxqabad deggan oo deegaanno kala duwan ah.
Xiriirka ka dhexeeya qaybaha rinjiga dhaldhalaalka alkyd iyo shaqadiisa ka hortagga miridhku
Dhammaan rinjiyada dhaldhalaalka alkyd kuma jiraan midabyo ka hortagga miridhku, sidaa darteed ma bixin karaan ilaalin ka hortagga miridhku. Marka la isticmaalayo rinjiyada dhaldhalaalka alkyd, waxaa lagama maarmaan ah in si taxaddar leh loo hubiyo halabuurka iyo ujeeddada loo adeegsaday badeecada si loo hubiyo inay leedahay sifooyin ka hortagga miridhku. Rinjiyada dhaldhalaalka alkyd ee kala duwan waxay leeyihiin awoodo ka hortagga miridhku iyo cimri dheer oo kala duwan, kuwaas oo ku xiran midabada ka hortagga miridhku ee ay ka kooban yihiin iyo dhumucda dahaarka.
Farqiga u dhexeeya rinjiga alkyd enamel iyo rinjiyada kale ee ka hortagga miridhku
Rinjiga birlabta ah waxaa laga sameeyaa varnish isagoo ah agabka saldhigga ah waxaana lagu diyaariyaa shiidid midabyo. Ka dib marka dahaadhku qalalo, wuxuu soo bandhigaa midabyo iftiin birlab ah wuxuuna leeyahay dusha adag. Noocyada caadiga ah waxaa ka mid ah rinjiga phenolic magnetic iyo rinjiga alkyd magnetic. Waxay ku habboon yihiin shabagga daaqadda birta ah iyo agabyada kale. Rinjiga ka hortagga miridhku wuxuu ka ilaalin karaa dusha birta daxalka kiimikada ama elektrokemikaalka ah ee ay sababaan jawiga iyo biyaha badda. Inta badan waxaa loo qaybiyaa laba qaybood: rinjiyada jirka iyo kiimikada ka hortagga miridhku. Rinjiga birlabta waxaa ka mid ah rinjiga zinc jaalaha ah, birta cas ee epoxy. Filimka rinjiga waa mid adag oo waara, oo leh dhejis wanaagsan. Haddii loo isticmaalo iyadoo lala kaashanayo ethylene phosphating primer, waxay hagaajin kartaa iska caabbinta kulaylka iyo iska caabbinta buufinta milixda. Waxay ku habboon tahay in loo isticmaalo sidii dahaadh saldhig ah oo loogu talagalay walxaha birta ee meelaha xeebaha iyo gobollada kulaylaha.
Rinjiga dhaldhalaalka ah ee alkyd waxaa loo arki karaa rinji aad u fiican oo ka hortagga miridhku, laakiin dhammaan rinjiyada dhaldhalaalka ah ee alkyd ma laha sifooyin ka hortagga miridhku. Kahor isticmaalka, waxaa lagama maarmaan ah in si taxaddar leh loo doorto badeecada oo la raaco tilmaamaha loogu talagalay isticmaalka iyo dayactirka si loo hubiyo saameynteeda ka hortagga miridhku iyo cimrigeeda adeegga.
