I-Alkyd wuhlobo lwe ukudweba equkethe i-polyester resin futhi ishintshwe ngamafutha acid, atholakala kuma-polyols, ama-organic acid, nama-triglycerides. Kuwuhlobo lukapende olususelwa kuwoyela oluziphatha ngendlela ehlukile kwezinye izinhlobo zikapende.
Upende we-alkyd ufana nopende we-koqweqwe lwawo, kodwa ngokuthungwa okuhlukile nomuzwa. Kuyinto enhle kakhulu yokukhetha izindonga zokudweba futhi inikeza isiphetho esihle okulula ukusisusa lapho sidingeka.
Lo mhlahlandlela uzokutshela konke okudingeka ukwazi mayelana nopende we-alkyd, kusukela kulokho oyikho kuye endleleni osetshenziswa ngayo.
Kulokhu okuthunyelwe sizomboza:
U-Alkyd: Ukhiye Wokuqeda Kakhulu Ezindongeni Zasekhaya Lakho
I-Alkyd yigama elichaza uhlobo lopende oluqukethe i-polyester resin eguquliwe ngokufakwa kwama-fatty acids nezinye izingxenye. I-Alkyds itholakala kuma-polyols nama-asidi e-organic, okuhlanganisa ama-dicarboxylic acid noma i-carboxylic acid anhydride kanye namafutha e-triglyceride. Igama elithi "alkyd" livame ukusetshenziswa embonini yepende ukuchaza uhlobo oluthile lopende owenziwe ngamafutha oluziphatha ngendlela ehlukile kunezinye izinhlobo zopende.
Ikhiqizwa Kanjani I-Alkyd Paint?
Inqubo yokukhiqiza upende we-alkyd ifana neyezinye izinhlobo zopende. Kodwa-ke, upende we-alkyd ngokuvamile uqukethe okuqukethwe okuphezulu kwamafutha ne-resin kunezinye izinhlobo zopende. Ukwengezwa kwalezi zingxenye kukhuthaza ukuguquguquka nokuvumelana emkhiqizweni wokugcina, okuholela endaweni eqinile lapho kupendwe ezindongeni.
Yiziphi Izinhlobo Ezihlukene ze-Alkyd Paint?
Kunezinhlobo eziningana ezahlukene zepende ye-alkyd etholakalayo, ngayinye enezici zayo ezihlukile kanye nezinzuzo. Ezinye zezinhlobo ezivame ukutholakala zopende we-alkyd zihlanganisa:
- Upende we-alkyd enamel: Lolu hlobo lukapende lwe-alkyd luhle kakhulu ukuthi lusetshenziswe ezindaweni zensimbi ngenxa yokuqina nokuqina kwayo.
- I-Hybrid alkyd paint: Lolu hlobo lwepende ye-alkyd luyinhlanganisela yepende ye-alkyd ne-latex, okwenza kube ukukhetha okuhle kulabo abafuna izinzuzo zazo zombili izinhlobo zopende.
- Upende we-alkyd osekelwe ngamafutha: Lolu hlobo lwepende ye-alkyd luvame ukusetshenziselwa ukudweba izindonga ekhaya, njengoba linikeza isiphetho esihle futhi kulula ukususa uma kudingeka.
Unganquma Kanjani Uma I-Alkyd Paint Ikulungele?
Uma ufuna isiphetho esihle ezindongeni zakho zasekhaya futhi uzimisele ukulinda isikhathi eside ukuze upende lome, upende we-alkyd ungase ube yisinqumo esifanele kuwe. Cabangela izici ezilandelayo lapho unquma ukuthi upende we-alkyd ulungele yini izidingo zakho zokudweba:
- Ingabe ufuna indawo eqinile ezindongeni zakho?
- Ingabe unentshisekelo yokudweba izindawo zensimbi?
- Ingabe uyafuna upende okulula ukuwusebenzisa futhi okunikeza isiphetho esingaguquki?
- Ingabe uzimisele ukulinda isikhathi eside ukuze upende wome?
- Uyawufuna upende okulula ukuwususa uma kudingeka?
Ukuthola Izimangaliso ze-Alkyd Paint: Umhlahlandlela Wochwepheshe
I-Alkyd paint inezici ezimbalwa eziyingqayizivele eziyenza ihluke kwezinye izinhlobo zopende, okuhlanganisa:
- Ukuqedwa okubushelelezi: Upende we-Alkyd unokuqeda okubushelelezi nokucwebezelayo okungenakuqhathaniswa nezinye izinhlobo zikapende.
- Ukumbozwa: Upende we-Alkyd ungamboza indawo ngejazi elilodwa noma amabili, okwenza kube ukukhetha okudumile kubadwebi abangochwepheshe.
- Ukumelana namanzi namakhemikhali: Upende we-Alkyd umelana kakhulu nokulimala kwamanzi namakhemikhali, okwenza ulungele ukusetshenziswa ezindaweni ezibhekene nezimo ezinzima.
- Ama-pigments amisiwe: Imibala kupende we-alkyd imisiwe ku-resin, okuvumela ukugcinwa kombala okungcono nokuqina.
- Ukusebenzisa ibhulashi: Upende lwe-Alkyd lungasetshenziswa ngebhulashi, okwenza kube lula ukulisebenzisa kubo bobabili ochwepheshe kanye nabathandi be-DIY.
I-Alkyd Paint Iqhathaniswa Kanjani Nabanye Opende?
Upende we-Alkyd uvame ukuqhathaniswa namapende asekelwe e-acrylic kanye namafutha. Nansi eminye yomehluko omkhulu:
- I-Acrylic: Opende be-Acrylic boma ngokushesha kunopende we-alkyd futhi kulula ukuwahlanza ngamanzi. Kodwa-ke, azihlali isikhathi eside njengopende we-alkyd futhi azinalo izinga elifanayo lokucwebezela.
- Amafutha: Amapende asekelwe ku-oyili athatha isikhathi eside ukuze ome kunamapende e-alkyd futhi adinga ama-solvents ukuze ahlanzeke. Abuye abephuzi ngokuhamba kwesikhathi. Kodwa-ke, anokuphela okushelelayo futhi avumelana nezimo kunopende we-alkyd.
Ukuqonda Izinhlobo Ezihlukene Zokuhlanganisa ze-Alkyds
Ama-alkyd kawoyela amade anomthamo kawoyela omningi, ngokuvamile ngaphezu kuka-60%. Zidinga isikhathi eside sokumisa kodwa zikhiqiza isiphetho esiqinile futhi esivumelana nezimo. Zivame ukusetshenziselwa amapende okupakisha okudla kanye nama-coatings.
Medium Amafutha Alkyds
I-alkyds kawoyela emaphakathi inowoyela osuka ku-40% ukuya ku-60%. Kulula ukuzisebenzisa futhi zikhiqiza isiphetho esihle. Asetshenziswa kakhulu ekwenzeni amathini kagesi kanye nenhloso evamile imichilo.
I-Alkyds eshintshiwe
Ama-alkyd ashintshiwe angama-alkyds ashintshiwe nezinye izingxenye ukuze athuthukise ukusebenza kwawo. Ezinye zezinguquko ezivame ukusetshenziswa zifaka ama-phenolic, i-bisphenol A, nama-acrylic monomers. Ukuguqulwa kuthinta isikhathi sokumisa, ukunamathela, ukumelana namakhemikhali, nokumelana nokushisa kokugqoka.
I-Alkyd Hybrids: Ingxube Ephelele Yezinhlansi
Ama-alkyd hybrids ayinhlanganisela ye-alkyd nezinye izinhlaka, njenge-epoxy, i-polyester, noma izinsalela zamanzi. Lawa ma-hybrids adalwe ngokuhlanganisa i-alkyd nama-precursors epoxy resin angaphenduliwe ngaphambi kokwelapha. Umphumela uba i-coating eyingqayizivele ehlanganisa izakhiwo ezinhle kakhulu ze-resin ngayinye.
Izinhlobo ze-Alkyd Hybrids
Kunezinhlobo eziningana zama-alkyd hybrids atholakalayo, okuhlanganisa:
- I-Epoxy-alkyd hybrids: Lezi zinhlobonhlobo zinikeza ukunamathela okuhle kakhulu nokumelana nokugqwala, okuzenza zilungele ukusetshenziswa ezindaweni zensimbi.
- I-Polyester-alkyd hybrids: Lezi zembozo zihlala isikhathi eside kakhulu futhi zinikeza ukugcinwa kwegloss okuhle kakhulu, okuzenza zilungele ukusetshenziswa ezindaweni zangaphandle.
- Ama-alkyd hybrids atholakala emanzini: Lezi zimbobo zihambisana nemvelo futhi zinikeza ukukhishwa kwe-VOC okuphansi, okuzenza zilungele ukusetshenziswa ezindaweni zasendlini.
- I-Nanocomposite alkyd hybrids: Lezi zimbobo ziqukethe ama-nanoparticles athuthukisa izici ze-coating, njengokumelana nokuklwebheka nokuvikelwa kwe-UV.
Isiphetho
Ngakho, yilokho i-alkyd eyikho- uhlobo lukapende oluqukethe ingxube yamafutha, inhlaka, nengcina. I-Alkyd inhle kakhulu ekudwebeni izindonga ngoba inikeza isiphetho esibushelelezi futhi imelana namanzi namakhemikhali. Ungayisebenzisa nasezindaweni ezingaphezulu zensimbi, ukwenze kube uhlobo lopende oluguquguqukayo. Ngakho-ke, uma ufuna isiphetho esiqinile, esiqinile, upende we-alkyd uyindlela okufanele uhambe ngayo.
