Kungenzeka nawe unayo amathini amabili kapende ekhaya lakho kanti elinye libhalwe ukuthi lisetshenziswe ngaphandle kanti elinye libhalwe ukuthi lisetshenziswe endlini. Kungenzeka ucabange ukuthi uma zombili zine-pigment efanayo nokukhanya okufanayo ... futhi ngukuthi zombili zisetshenziselwa ukupenda izindawo. Kepha uma usebenzisa ingaphandle langaphandle noma upende wangaphandle wangaphakathi, imiphumela kungenzeka ingabi yilokho obukulindele.
I-chemistry etholakala ezingxenyeni zokupenda namuhla ishintshile kusuka eminyakeni embalwa emuva manje. Abakhiqizi kanye nochwepheshe ngokufanayo batusa ukusebenzisa amathini opende ngokuya ngokuthi abhalwe kanjani: upende wangaphakathi wezindawo zangaphakathi nopende wangaphandle wezindawo ezingaphandle.
Lapho ukhetha upende
Uma uyokhetha upende kunezinto ezimbili eziyisisekelo okufanele uzazi: kukhona upende osuselwa emanzini nopende osuselwa ku-oyela. Upende weLatex, upende we-acrylic ususelwa emanzini, kuyilapho upende we-alkyd ungowoyela. Womabili la mapende ayizinto zangaphakathi. Kunezinhlobo ezahlukene zokupenda kwangaphandle.
Uma kukhulunywa ngopende wangaphandle, upende osuselwa kuwoyela ungcono ngoba umelana nokungcola. Yize upende we-latex osuselwa emanzini uvame ukusetshenziselwa izindawo ezingaphandle ngoba uvame ukuhlala isikhathi eside kunowoyela. Lolu hlobo lukapende uma lusetshenziswa ezindaweni ezingaphandle lumelana kangcono nomswakama, izinto ezingaphandle, ukushintsha kwezinga lokushisa, futhi futhi kuthatha isikhathi esincane kakhulu ukoma.
Upende osetshenziselwa ingaphandle uqukethe izithasiselo ezibanika impilo ende ende ezindaweni ezingaphandle, ziphikisana kangcono nokuqhekeka kanye nomphakathi. Ngaphezu kwalokho, upende wangaphandle waklanywa ngendlela yokuthi ukwazi ukumelana kangcono nomonakalo ongabangelwa yimisebe ye-UVA.
Amapende asuselwa emanzini alungele izinto zangaphakathi. Esikhundleni sokuba nezithasiselo zokumelana nokungcola kangcono, i-chemistry yamapende angaphakathi yenzelwe ukuthi ibe lukhuni futhi inamathele. Futhi zenzelwe ukumelana nokungcola okujwayelekile kwanoma iyiphi indawo yasendlini (splashes, rubbing, njll.).
Umehluko phakathi kwezingxenye zokupenda zangaphandle nezangaphakathi
Ukuntuleka kwezinye izithasiselo kunikeza okuthile okungahambi kahle kupende wangaphakathi lapho kusetshenziswa ezindaweni zangaphandle. Umehluko phakathi kopende owenziwe ngaphakathi nangaphandle awupheli lapha. Umehluko ubuye ubonakale lapho ubheka ezinye izingxenye zepende: ama-pigment, ama-binders kanye noketshezi.
I-pigment
I-pigment yilokho okuhlinzeka ngopende ngombala. Upende wangaphakathi ungaqukatha imibala yombala ophilayo kepha ungaphela uma usetshenziswa ngaphandle. Amafomula okupenda angaphandle agwema lezi zingulube ukukhulisa amandla kapende ongaphandle.
Ukuhlanganisa
Upende wenziwa ngezithasiselo ezaziwa ngokuthi ama-binders, ezisetshenziselwa ukubopha i-pigment futhi ngasikhathi sinye zinikeze ukunamathela komhlaba lapho kuzopendwa khona. Amapende wangaphandle kufanele amelane kakhulu nokumelana nemiphumela emibi yendawo. Ngale ndlela upende uyahluleka ukumelana nemifantu futhi ulawula kangcono umswakama.
Izimila
Upende lwangaphakathi nolwangaphandle luyehluka futhi ezinhlotsheni zeziphuzo ezisetshenziselwa ukwakha uhlobo olulodwa lukapende nolunye. Upende wangaphakathi, ikakhulukazi upende wangaphakathi osuselwa emanzini, kufaka phakathi i-latex, enzelwe ukuthi aqukethe amazinga aphansi kunawo wonke we-organic compounds (VOCs). Ama-VOC asetshenziswa njengamakhemikhali awuketshezi engxenyeni ketshezi kapende futhi aphefumule ekamelweni lokushisa. Ama-VOC axhumene nezinkinga zezempilo zesikhashana nezesikhathi eside, kusuka ekhanda nasesiyezi (esifushane) kuya ezifweni zokuphefumula kanye nokulimala kwesibindi (isikhathi eside).
Zingabuye zihlotshaniswe nomdlavuza othile. Udinga ukuthola upende onama-VOC anamazinga aphansi kakhulu noma awekho.
Ngakho-ke ngingakwazi yini ukusebenzisa upende wangaphakathi ezindaweni ezingaphandle?
Uma usufinyelele kuleli qophelo, uzokwazi ukuqinisekisa ukuthi kungcono ukuthi uma uzopenda indawo yangaphakathi usebenzise upende owenzelwe wona. Kwenzeka okufanayo uma uzopenda indawo engaphandle, lapho-ke kungcono ukuthi uthenge futhi usebenzise upende ohloselwe kuphela ukudweba izindawo ezingaphandle. Ungathola amapende angaphandle anconywe kakhulu kulesi sixhumanisi.
Uma ungabaza ukuthi imuphi upende ongalungela indawo ethile yekhaya lakho, kuzodingeka ukuthi ubuze uchwepheshe wokudweba ukuze bakwazi ukukuqondisa. Uma uzopenda indlu yakho ngaphandle nangaphakathi, kufanele ube nezinhlobo ezimbili ezihlukene zamakani kapende, eyodwa eyenzelwe umdwebo wangaphakathi nenye ehloselwe ukudweba ngaphandle. Lapho usukwazi lokhu, kufanele ukhethe umbala owuthanda kakhulu futhi uthenge amathuluzi afanele!
