Daawada impregnation waxaa loo isticmaalaa in lagu dhejiyo gariiradaha korantada iyo dabaylaha si loo buuxiyo godadka ku dhex jira, si fiilooyinka gariiradaha iyo fiilooyinka iyo agabyada kale ee daahyada la isku xiro si loo hagaajiyo xoogga korantada, sifooyinka farsamada, kuleylka kulaylka iyo sifooyinka ilaalinta korantada dahaarka gariiradda. Ms. Can waxay maanta kula yeelan doontaa dood kooban oo ku saabsan varnish-ka impregnation, iyadoo rajaynaysa inay kaa caawiso habka ilaalinta tayada.
1 Shuruudaha aasaasiga ah ee varnish gariiradda korantada impregnation
● Mawduuc hoose iyo maaddooyin adag oo sarreeya si loo hubiyo ka-soo-baxa wanaagsan iyo cadadka rinjiga laadlaadsan;
● Degenaansho wanaagsan inta lagu jiro kaydinta iyo isticmaalka;
● Daweynta wanaagsan iyo dabeecadaha qalajinta, daweynta degdega ah, heerkulka hooseeya, qalajinta gudaha ee wanaagsan;
● Xoog isku xirnaanta sare, si qalabka korantada uu u adkeysto xawaaraha sare iyo saameynta xoogga farsamada;
● La jaanqaadi kara agabka kale ee ka kooban;
● Waxqabadka deegaanka ee wanaagsan.
2 Kala soocida iyo sifooyinka varnish impregnation
● Dareemka impregnation ee dareeraha. Dareemka impregnation-ka dareeraha ah wuxuu ka kooban yahay dareere, iyo maadada adag (jajabka tirada badan) inta badan waa inta u dhaxaysa 40% iyo 70%. Dareemka impregnation dareere leh maaddo adag oo ka weyn 70% waxaa loo yaqaannaa varnish impregnation hoose, sidoo kale loo yaqaan varnish adag impregnation.
Dareemka impregnation Solvent wuxuu leeyahay xasillooni kaydineed oo wanaagsan, sifooyin wanaagsan iyo sifooyin filim-samayn ah, waana mid raqiis ah, laakiin wakhtiga wax lagu dubo iyo dubista ayaa dheer, dareeraha haraaga ah wuxuu keeni doonaa nusqaamo ku yimaada walxaha uurka leh. Walxaha qallafsan ayaa sidoo kale keena wasakhowga deegaanka iyo qashinka, isticmaalkeeduna waa xadidan yahay. Waxaa inta badan loo isticmaalaa impregnation eematoorada korantada yariyo dabaylaha korontada.
Faakiska impregnation-free-free waxaa badanaa lagu uureeyaa immersion, iyo cadaadiska faakuumka impregnation iyo dhibic sidoo kale waa la isticmaali karaa.
Fuuq-baxa aan milmaha lahayn ayaa si dhakhso ah u daaweeya, waxa ay leedahay wakhti gaaban oo wax lagu dubo, wax hawo ah kuma laha dahaarka uurka leh, waxa uu leeyahay daacadnimo wanaagsan, waxana uu leeyahay sifooyin koronto iyo farsamo sare leh. Faalshka impregnation-free-free ayaa si weyn loo dalacsiiyay oo lagu dabaqay si loogu beddelo varnish impregnation-ka-la'aanta ah ee koronto-dhaliyeyaasha-sare, matoorada, baaxadda weyn, khadadka wax-soo-saarka degdegga ah, iyo matoorrada gaarka ah iyo qalabka korontada. Si kastaba ha ahaatee, muddada kaydinta ee varnish impregnation-free dareere waa gaaban. Faalshka impregnation-la'aanta ah waxaa lagu nuumi karaa immersion, immersion joogto ah, is-rog-rogid, biyo-dhicitaan iyo cadaadis vacuum ah.
3 Ka taxadar isticmaalka varnish impregnation
●Maareynta tayada leh ee varnish impregnation inta lagu jiro isticmaalka. Rinjiga aan milmayn waa ka samaysan resin polymerizable ah. Noocyo kala duwan oo rinji impregnation-free aan dareere ah ayaa is-polymerize doona heerar kala duwan inta lagu jiro kaydinta iyo isticmaalka. Maaraynta khaldan waxay soo dedejin doontaa is-polymerization-kan. Marka rinjiga aan dareeraha lahayn ee ku jira qalabka impregnation uu soo saaro jel, si dhakhso ah ayuu u adkaan doonaa oo waa la tirtiri doonaa 1 ilaa 2 maalmood gudahood, taasoo keenta shilal iyo khasaare waaweyn. Sidaa darteed, tayada rinjiga impregnation-la'aanta ah ee la isticmaalo waa in si adag loo maareeyaa, waana in la qaado tallaabooyin lagu hubinayo xasilloonida tayada rinjiga.
(1) Si joogto ah ula soco oo ula soco tayada rinjiga uurka leh ee la isticmaalayo. Alaabta kormeerka iyo wareegyada kormeerka waxaa loo qaabayn karaa iyadoo loo eegayo rinjiga impregnation ee la isticmaalay, qalabka wax-soo-saarka iyo hawlaha wax-soo-saarka. Alaabta kormeerka guud ahaan waxaa ka mid ah cufnaanta, cufnaanta, wakhtiga jel, qoyaanka ka kooban yahay iyo waxyaale firfircoon. Haddii tusmada tayada rinjiga ay dhaafto xadka sare ee tusaha kontoroolka gudaha, rinji cusub ama tallaabooyin kale waa in isla markiiba la qaado si loo hagaajiyo.
(2) Ka ilaali qoyaanka iyo wasakhda kale inay galaan rinjiga uurka leh. Haddii epoxy ama polyester-ka dareeraha-free rinjiga impregnating waa mid aad u nugul qoyaanka. Qaddar yar oo qoyaan ah oo soo galaya nidaamka waxay keeni doontaa viscosity ee rinjiga si degdeg ah u kaca. Qoyaanka iyo wasakhda waa in laga ilaaliyaa inay soo galaan rinjiga inta lagu jiro gaadiidka, kaydinta iyo isticmaalka rinjiga uurka leh. Biyaha, hawada iyo molecular volatiles hoose ee isku qasan ee rinjiga waxaa laga saari karaa by faakiyuumka iyo lakabka ranjiga ah qalabka degasing, iyo dareeraha ranjiga lagu sifeyn karaa qalab shaandhaynta. Xuubka ku jira rinjiga si joogto ah ayaa loo sifeeyaa si loo nadiifiyo.
(3) Si sax ah u dooro heerkulka impregnation si viscosity ee rinjiga u gaaro qiimaha la cayimay. Tan waxaa lagu dooran karaa iyadoo lagu saleynayo qalooca heerkulka viscosity-heerkulka ee rinjiga, iyadoo la tixgelinayo farqiga u dhexeeya qalabka-qabow-qabow iyo kuwa-kuleelka shaqada. Haddii heerkulku aad u sarreeyo, waxay saameyn xun ku yeelan doontaa xasilloonida viscosity ee rinjiga; haddii heerkulka wax lagu shubo uu aad u hooseeyo, viscosity-ku wuu sarreeyaa saameyntuna waa liidataa.
(4) Si joogto ah u wareeg oo u walaaq dareeraha rinjiga si aad u ilaaliso heerkulka dareeraha rinjiga ee taangiga rinjiga iyo dhuumaha sida ugu hooseeya ee suurtogalka ah si looga hortago in dareeraha rinjiga ee dhuumaha uu is-xojiyo oo uu adkeeyo, kaas oo xannibi doona dhuumaha rinjiga.
(5) Ku dar rinji cusub si joogto ah. Wareegga kordhinta iyo qadarku waxay ku xiran tahay hawsha wax soo saarka iyo nooca rinjiga. Marka lagu daro rinji cusub oo hoos yimaada hawlaha caadiga ah ee wax soo saarka, rinjiga impregnation ee taangiga waxaa badanaa loo isticmaali karaa si adag muddo dheer.
(6) Kaydinta heerkulka hooseeya waxay yaraynaysaa xawaaraha is-polymerization ee rinjiga. Heerkulka kaydinta waxaa lagu xakameyn karaa wax ka hooseeya 10 ° C. Xaaladaha aan muddada dheer la isticmaalin ama xaaladaha, heerkulka kaydinta waa inuu ka hooseeyaa, sida -5 ° C.
Rinjiga impregnation ee dareeraha ah, diiradda ayaa ah in si joogto ah loo hubiyo cufnaanta iyo viscosity ee rinjiga si loogu ilaaliyo xadka xakamaynta.
● Saamaynta wasakhdu ku leedahay daawaynta rinjiga impregnation polyester-ka ee aan dheregsanayn. Ku celcelinta ayaa muujisay in walxaha sida naxaasta iyo phenols ay dib u dhac ku leeyihiin daawaynta rinjiga impregnation polyester-ka ee aan saturated lahayn. Walxaha kale qaarkood, sida caag iyo silig dhalaalay oo saliid leh, ayaa lagu milmi doonaa ama bararsan doonaa monomer-ka firfircoon ee styrene ee rinjiga impregnation, taas oo ka dhigaysa dusha sare ee workpiece-ka uurka leh.
● Arrimaha ku habboonaanta. Tijaabooyin ku habboonaanta waa in la sameeyaa si loo hubiyo in rinjiga impregnation uu si buuxda ula jaan qaadayo walxaha kale ee nidaamka dahaarka.
●Arimaha habka dubista. Faallooyinka impregnation-ku-saleysan ee dareeraha waxaa ku jira xaddi badan oo dareere ah. Guud ahaan, laba ama in ka badan oo impregnation, dubista iyo heerkulka tartiib tartiib ah u kordho hababka dubista ayaa loo isticmaalaa si looga hortago pinhole ama daldaloolo filimka rinjiga iyo hagaajinta waxqabadka iyo nolosha dahaarka gariiradda. Habka dubista ee varnishes impregnation-free dareere waa in ay taxaddaraan si looga hortago qulqulka xabagta xad-dhaaf ah. Dubidda Rotary waxay si wax ku ool ah u dhimi kartaa qulqulka xabagta.
●Arimaha wasakhowga deegaanka. Tallaabooyin ku habboon waa in la qaadaa si loo xakameeyo uumiga dareeraha ah iyo styrene ee sii daaya inta lagu jiro nidaamka rimidda iyo dubista gudaha xadka la oggol yahay ee la oggol yahay.
