Si aad dusha ka saamayn taban, oo ay ku jiraan dhaldhalaalka polyurethane cimilada, ayaa maanta si weyn loo isticmaalo, taas oo ah waxaa la bixiyaa sale in tiro balaadhan oo loo ilaaliyo. Isku dar ah Tani waxay ka dhigan tahay polymers kala duwan isagoo guryaha jidaar. Haddii la barbardhigo ah Halabuurka this la formaldehyde kale, dhaldhalaalka polyurethane ee aan awoodi karin helin muuqashadii kale. Marar badan, oo sideeda oo waxaa loo isticmaalaa sida daahan difaac, tan iyo markii filimka ayaa margin sare ah ammaanka.

Qoondaynta oo ah enamels polyurethane

isku polyurethane waxaa loo qaybiyey wax in la daboolo, iyo sidoo kale nooca codsiga iyo Halabuurka. waxaa loo isticmaali karaa si aad u dalbato burush gaar ah ama dhalada buufis. Field isticmaalka dhaldhalaalka polyurethane noocyada kala duwan ballaaran oo lagu saleyn karaa a dhagax, qori ama bir. Ka hor inta la isticmaalayo alwaax polyurethane isku dar ah looma baahna in ra'iisul, laakiin waa in la si fiican qalajiyey.

astaamaha farsamo

One-qayb dhaldhalaalka polyurethane waa Halabuurka a in la sameeyo ka polyurethane, Midabka iyo dareeraha. Waxaa ka mid ah sifooyinka ugu muhiimsan ee daryaa waa in la iftiimiyay:

• cimri dherer,
• barti,
• harmlessness ka dib markii uumi ee dareeraha ah,
• xasiloonida kiimikada.

walxuhu polyurethane dhammaataan hogaansamo meelaha ugu adag.

Kala duwan ee enamels polyurethane

dhaldhalaalka polyurethane laga yaabaa kala firidhsan aqueous. Ka mid ah faa'iidooyinka ku jira harmlessness ee masraxa dyeing iyo suurtagalnimada of Barxo biyo saafi. Ma ku haboon yahay dyeing meelaha hydrophobic enamels sida. Tani waa in ka mid ah la taaban karo, ahama oo caag ah.

Polyurethane ka kooban bedelidii gaar ah kiimikada kaas oo u ogolaanaya oo sideeda oo lagu kaydiyaa foomka of kala firidhsan ah aqueous of ma Adkaan. Tani waxay u ogolaaneysaa for daahan Duugga u adkaysta xoog leh. Haddii loo baahdo, xayd dabaqa goobta shaqada waxaa lagu talinayaa in la siiyo doorashada si kooban dareeraha organic.

dhaldhalaalka polyurethane qase organic

dhaldhalaalka polyurethane lagu samayn karaa oo ku salaysan qase organic, sida xylene ama toluene. Si fiican u isticmaal tirada qase Barxo, kuwaas oo lagu taliyey by saaraha. Ka dib markii Asagoo arigtadaa ka, taas oo qaadataa laba maalmood, daahan uu noqdo mid tayo leh, u bixiyey faa'iidooyinka ugu muhiimsan: cimri dherer, iska caabin ah biyaha, iska caabin ah warbaahinta dagaal badan.

rinjiga polyurethane dhaldhalaalka kale waa alkyd-urethane, waxay waxaa loo isticmaalaa in la abuuro daahan ah laastikada iyo waarta taas oo si tartiib ah adkaynayaa, oo uu leeyahay ur khafiif ah inta lagu guda jiro dyeing. Qiimaha isku dar oo kale ah oo si weyn u hooseysa marka loo eego enamels urethane hal qayb.

Description laba-qayb enamels polyurethane

Dhaldhalaalka ka kooban yahay laba-qayb hardener polyurethane iyo dhaldhalaalka, kuwii hore ka mid ah taas oo lagu daray inta aan la isticmaalin. Isku dar ah waligiiba meelmar ah muddo 3 saac ah, oo lagu qalajiyo socdaa 6 saacadood. Qiimaha wax tani waa sarraysaa sida xoogga daahan. dhaldhalaalka polyurethane noocan oo kale ah in ay biraha loo isticmaali karaa biraha in la raran ku hoos jira xaalad-soo-saarka iyo dukaamada kulul ku shaqeeya oo leh jawi dagaal badan.

Xadka sare ee heerkulka hawlgalka ee isku dar ah waa la +80 ° C iyo gaari karto heer ah 100 ° C. Haddii ay jirto baahi ah si ay u dedaan dhismaha, taas oo loo isticmaali doono in xaaladaha dab, waxaa lagama maarmaan ah si ay u iibsadaan darey gaar ah. Tusaale ahaan, renjiga on biraha "Polysteel" markii loo feydo kulka ah si ay u sameeyaan xumbo carbon oo si ammaan ah hor joogsadaa kuwa ku tiilna olol iyo kulaylkii qalabada in saacadaha 1.5 ah.

Codsiga of dhaldhalaalka polyurethane "Elakor-PU"

Haddii aad u baahan polyurethane dhaldhalaalka priming, lacag bixisid si aad ah "Elakor-PU", qiimaha halkii kiilo oo 275 rubles dareenka. Halabuurka Tani waa in la dalbadaa xaaladaha qaarkood, kuwaas oo muujiyay sida ay ka maqan yihiin hoose ee u kaca biyaha gaddoonka ah. Waxaa muhiim ah sidoo kale ay goobjoog ka ahaayeen xireyaashaba salka. dusha qoyaanka haraaga ah waa in aanay noqon in ka badan 5%. Ka hor inta codsanaya Halabuurka ee dusha uu uga takhalusi meelaha dufan leh. Marka ay timaado in la aasaasin la taaban karo, waa in la keenan leh makiinad gaar ah si loo soo saaro haraadiga hore rinjiga, wasakh iyo laitance.

Ka hor inta dhaldhalaalka polyurethane la taaban karo waxaa laga codsadaa, dusha sare waa in la dedusted isticmaalaya ah huufarka warshadaha, iyo ka dib markii cover Primer ka soo saaraha isku mid. Ka hor inta isticmaalka, isku dar ah si fiican u kiciyey, iyo waxaa lagama maarmaan ah in aad dalbato a polyamide rullaluistemadka 4 lakabka. Tirada ugu yar ee layers waa 2, tirada final dul ujeeddooyinka eryadeen ku xirnaan doontaa. Inta u dhaxaysa layers waa lagama maarmaan in la sugo oo ku saabsan 4-8 saacadood.

Dalbashada la taaban karo dhaldhalaalka "Elakor PU-dhaldhalaalka-60"

dhaldhalaalka Tani waa mid ka-qayb semigloss midab isku dar ah qoyaan-daaweynta sida faa'iido ugu weyn ee kaas oo ah suurtagalnimada codsiga marka heerkulku hooseeyo. Ka dib markii polymerization ah, la aasaasay Duugga u adkaysta caag dusha polymer adag taas oo iska caabin ah kiimikada kala duwan.

Diyaarinta iyo daahirinta ku been dusha priming kaas oo la dahaarka leh ka dib markii dhaldhalaalka at heerkul ah ka -30 in +25 ° C. ah Heerkulka mid ah waxyaabaha la kala duwanaan karaa ka +10 in +25 ° C. Waa muhiim in la tixgeliyo huurka qaraabo ah hawada, waa in aan ka badnayn 80%. Ka hor inta aan codsiga ka kooban yahay isku qasan ilaa midabka direyska iyo joogto ah. Waayo, fiicni this waxaa loo isticmaali karaa rinjiga, kaas oo la geliyo dardarta kala duwan ee ka 400 600 halkii daqiiqo.

Waayo, shaqada, waxaad isticmaali kartaa rollers ama burush, kuwaas oo adkaysi u milma. Waxaad isticmaali kartaa technology buufiyo godadka. In mid ka mid ah lakabka, meel ka mid ah mitir laba jibaaran, qaadan doonaa qiyaastii 150 g dhaldhalaalka. natiijada kama dambaysta ah waxay ku xirnaan doontaa macaanaa ee dusha sare. qalajiyo heerarka socdaa tiro la mid ah waqtiga, sida ku haysta muuqashadii kor ku xusan.

gunaanad

Haddii aad go'aansato in aad isticmaasho halabuurka ah polyurethane laba-qayb, waa in aan xisaabta in ay codsiga looma fuliyo on meelaha qoyan galay. looga baahan yahay Tan waxa u sabab xaqiiqada ah in wakiilka Daaweynta la dioxide kaarboon in la sii daayo dareeraha, kaas oo ku kordhinaya ka xumbaynaya ee dusha sare fal.
