1. Doorka alaabta buuxinta
Ku dar waxyaalaha buuxiya sida kaalshiyam carbonate, dhoobo, aluminium hydroxide, dhalada dhalada, microbeads galaas, iyo lithopone ilaa xabagta polyesterka oo kala fir si aad u abuurto isku dhafka resin.Shaqadeedu waa sida soo socota:
(1) Hoos u dhig qiimaha alaabta FRP (sida calcium carbonate iyo dhoobada);
(2) Yaree heerka daawaynta ee hoos u dhaca si looga hortago dildilaaca iyo qallafsanaanta ay keento yaraanta (sida calcium carbonate, budada quartz, microspheres galaas, iwm.);
(3) Hagaaji viscosity resin inta lagu guda jiro qaabaynta oo ka ilaali dheecaanka resinka.Si kastaba ha ahaatee, waa in la ogaadaa in kororka xad-dhaafka ah ee viscosity uu mararka qaarkood noqon karo khasaare;
(4) Hufnaan la'aanta alaabta la sameeyay (sida calcium carbonate iyo dhoobo);
(5) Cadaynta alaabta la sameeyay (sida barium sulfate iyo lithopone);
(6) Hagaajinta iska caabbinta daxalka ee alaabta la sameeyay (mica, xaashida dhalada, iwm.);
(7) Hagaajinta caabbinta ololka ee alaabta la sameeyay (aluminium hydroxide, antimony trioxide, paraffin koloriin leh);
(8) Hagaajinta adkaanta iyo qallafsanaanta alaabta la sameeyay (sida calcium carbonate, microspheres galaas, iwm.);
(9) Hagaajinta xoogga alaabta la sameeyay (budada galaaska, fiilooyinka potassium titanate, iwm.);
(10) Hagaajinta sifooyinka khafiifka ah iyo dahaarka ee alaabta la shubay (microspheres kala duwan);
(11) Bixi ama kordhi thixotropy ee isku dhafka resin (sida ultrafine anhydrous silica, budada dhalada, iwm.).
Waxaa la arki karaa in ujeedada loogu daro buuxinta resins ay kala duwan tahay, sidaas darteed waxaa muhiim ah in la doorto buuxinyaal ku habboon iyadoo loo eegayo ujeedooyin kala duwan si si buuxda looga faa'iidaysto doorka buuxinta.
2. Ka taxadar xulashada iyo isticmaalka buuxinta
Waxaa jira noocyo kala duwan oo buuxin ah.Sidaa darteed, waxaa lagama maarmaan ah in la doorto calaamad ku habboon buuxinta iyo darajada ujeedada isticmaalka, taas oo aan la sheegin.Taxaddar guud marka la dooranayo buuxinta ma aha oo kaliya in la doorto kala duwanaanta qiimaha iyo waxqabadka hore loo go'aamiyay, laakiin sidoo kale in fiiro gaar ah loo yeesho qodobada soo socda:
(1) Qadarka resin la nuugo waa inuu ahaadaa mid dhexdhexaad ah.Qadarka xabagta la nuugo waxay saameyn weyn ku leedahay viscosity ee isku dhafka resinka.
(2) Viscosity ee isku dhafka resin waa inuu ku habboon yahay hawlgalka qaabeynta.Dhowr habayn oo lagu sameeyo viscosity of resin isku darka ah ayaa lagu samayn karaa iyada oo lagu milo styrene, laakiin lagu daro buuxinyaal aad u badan iyo ku milo styrene waxay horseedi doontaa hoos u dhac ku yimaada waxqabadka FRP.Viscosity ee isku dhafka resinka ayaa mararka qaarkood si weyn u saameeya qadarka isku dhafka ah, xaaladaha isku dhafka, ama ku darida beddelayaasha dusha sare.
(3) Sifooyinka daawaynta ee isku dhafka resin waa in ay ku habboonaadaan xaaladaha wax-qabashada.Sifooyinka daawaynta ee isku dhafka resin-ka waxaa mararka qaarkood saameyn ku leh buuxinta lafteeda ama qoyaanka la isku daray ama isku qasan iyo walxaha shisheeye ee ku jira buuxinta.
(4) Isku darka resinku waa inuu ahaado mid deggan muddo cayiman.Dhacdada dejinta iyo kala-soocidda alaab-buuxiyeyaasha sababtoo ah joogsiga, waxaa laga yaabaa in mararka qaarkood laga hortago iyada oo la siinayo thixotropy.Mararka qaarkood, habka looga fogaado static iyo walaaqo farsamaysan joogto ah ayaa sidoo kale loo isticmaalaa si looga hortago dejinta ee buuxinta, laakiin kiiskan, waxaa lagama maarmaan ah in la tixgeliyo ka hortagga dejinta iyo raasamaal ee buuxinta ee dhuumaha ka weelka ka kooban qaso si ay u sameeyaan. goobta.Marka qaar ka mid ah kuwa buuxinaya microbead ay u nugul yihiin kala soocida kor u kaca, waa lagama maarmaan in dib loo xaqiijiyo darajada.
(5) Maqnaanshaha isku dhafka resin waa inuu ku habboon yahay heerka farsamada hawlwadeenka.Ku darida buuxinta guud ahaan waxay yaraynaysaa hufnaanta isku dhafka resin waxayna sidoo kale yaraynaysaa ductility resin inta lagu jiro lakabyada.Sidaa darteed, impregnation, hawlgalka xumbo-dejinta, iyo xukunka inta lagu jiro qaabaynta ayaa noqday mid adag.Qodobadan waa in la tixgeliyo si loo go'aamiyo saamiga isku dhafka resin.
(6) Waa in fiiro gaar ah loo yeesho cufis-jiidka gaarka ah ee isku dhafka resin.Markaad buuxinta u adeegsanayso agabka kordhinta si loo dhimo kharashyada alaabta, cufis-jiidka gaarka ah ee isku dhafka resinku wuu kordhiyaa marka la barbar dhigo resin-ga, mararka qaarkoodna aan la kulmin qiimaha la filayo ee si dareen leh u dhimaya kharashyada alaabta.
(7) Saamaynta wax ka beddelka dusha sare ee buuxinyaasha waa in la sahamiyaa.Wax-ka-beddelayaasha dusha sare waxay wax ku ool u yihiin dhimista viscosity of resin isku darka ah, iyo wax ka beddelayaasha dusha kala duwan ayaa mararka qaarkood hagaajin kara awoodda farsamada marka lagu daro iska caabbinta biyaha, caabbinta cimilada, iyo caabbinta kiimikada.Waxa kale oo jira noocyo buuxinayayaal ah oo lagu sameeyay daawaynta dusha sare, qaarna waxay isticmaalaan waxa loo yaqaan "habka isku dhafka oo dhan" si wax looga beddelo dusha sare ee buuxinta.Taasi waa, marka la isku daro isku-dhafka resin-ka, buuxinta iyo wax-beddelayaasha ayaa lagu daraa xabagta, mararka qaarkood saameyntu aad bay u fiican tahay.
(8) Xumbo-xumaynta ku jirta isku-dhafka resin-ka waa in si fiican loo fuliyaa.Buuxiyeyaasha waxaa badanaa loo isticmaalaa qaab budo yar yar iyo qaybo, oo leh meel sare oo aad u weyn.Isla mar ahaantaana, waxaa sidoo kale jira qaybo badan oo budo yar yar iyo qaybo isku dhafan oo midba midka kale ah.Si loo kala firdhiyo waxyaalahan buuxinaya xabagta, resinku waxa uu u baahan yahay in uu maro walaaq aad u daran, waxaana hawada la galinayaa isku dar ah.Intaa waxaa dheer, hawada ayaa sidoo kale lagu sawiraa mugga weyn ee buuxinta.Natiijo ahaan, xaddi aan la qiyaasi karin oo hawo ah ayaa lagu qasi jiray isku darka resin ee diyaarsan, iyo xaaladdan, FRP-ga lagu helo sahayda qaabaynta waxay u nugul tahay inay soo saarto xumbo iyo faaruq, mararka qaarkoodna ay ku guuldareysato inay gaarto waxqabadkii la filayay.Marka aysan suurtagal ahayn in si buuxda loo xumeeyo oo kaliya adigoo taagan ka dib marka la qaso, sifeynta bacda xariirta ama dhimista cadaadiska ayaa loo isticmaali karaa in meesha laga saaro xumbo.
Marka lagu daro qodobada kor ku xusan, tallaabooyinka ka hortagga boodhka waa in sidoo kale lagu qaadaa jawiga shaqada marka la isticmaalayo buuxinta.Walxaha ay ka midka yihiin ultrafine particulate silica oo ka kooban silica bilaashka ah, alumina, diatomaceous earth, dhagxaan la qaboojiyey, iwm. waxaa lagu sifeeyay inay yihiin siigada Class I, halka kaalshiyam carbonate, budada dhalada, dhalada dhalada, mica, iwm lagu sifeeyay sida fasalka II boodhka.Waxa kale oo jira xeerar ku saabsan fiirsashada la xakameeyey ee budo yaryar oo kala duwan ee jawiga deegaanka.Aaladaha qiiqa deegaanka waa in la rakibaa waana in si adag loo isticmaalo qalabka ilaalinta shaqada marka la qabanayo buuxinta budada ah.
