Ipeyinti Water: iinkcukacha, abenzi, ukubunjwa

Industrial bokubeka bepeyinta iindonga, iisilingi, esithuba somgangatho, ifenitshala ngayo, kwakunye window kunye ucango yoyilo badla asebenzise ipeyinti esekelwe phezu emulsion zolwelo. Ipeyinti latex, iimpawu zobugcisa zinika bengxelo-enganyangekiyo kunye ezikumgangatho ophezulu umbala, hi-zobugcisa kwaye akukho neziphumo yityhefu kwi eziphilayo.

Principles of ukubunjwa zokukhusela nokwakhiwa ipeyinti yamanzi-based

Isihloko latex (i nkcithakalo zolwelo) uchaza kungenxa phambi emanzini-based sombala oluludaka yayo kunye azakhele emulsion. izinto saa zixubene into zolwelo medium, kwaye zakhiwa kwaye ezikhoyo ngaxeshanye nalo.

Ngenxa yoko, Latex iqulathe lokufaka, a thickener, kunye latex kubola.

Amasuntswana Polymer emva kokuba amanzi yomile phezu zakha umaleko flat kolirovanny. paint Undried kungaba lula ngesandla, kwaye umaleko yayo akukho livumba elibi. Peyinta ukumelana nempembelelo ngomatshini, kodwa isicelo Imiphezulu yesinyithi ukuthintela umhlwa kwi ubukho ukufuma rhoqo.

Iimpawu eziphambili zobugcisa ipeyinti yamanzi-based

Ipeyinti latex, iimpawu zobugcisa apho - le viscosity, umyinge, flow womxhuzulane ezithile kunye nexesha omiswe, kukho intsebenzo yemveliso oluzinzileyo, Lifanele ngenxa yonyango imiphezulu lwangaphakathi kweendawo zokuhlala.

The degree of ukuxutywa kunobukhulu idayi ngamanzi uthe index viscosity ilinganiswa usebenzisa rheometer.

Flow izinga ipeyinti emulsion ixhomekeke absorbency na ukwamkelwa komhlaba kwaye ukusuka ml 100 ukuya 200 square metre of komhlaba nganye, i-inki umaleko obudaywe yenye millimitha zamafu.

Specific paint weight latex imalunga 1.3 eekhilogram ilitha nganye.

Iyoma latex yokupeyinta ixesha ixhomekeke ukufuma kunye nobushushu, ukusukela iiyure ezimbini ukuya ngenye imini. iimeko elilelona ingqalelo umoya lobushushu yokomisa degrees 20 Celsius ne-65% nokufuma.

Ubomi lokugcinwa kwezinto le iipeyinti emulsion ixhomekeke kakhulu iimeko zayo yokugcina (in an efanelekileyo - indawo emnyama epholileyo), kunye umlinganiselo kweenyanga ezingama-24.

Iinkcukacha inki yamanzi-kwiintsali kuboniswa ngokupheleleyo GOST data 28196-89.

Ukucacisa GOST

Latex, iinkcukacha (GOST) ezibhaliswe phantsi kwinani 28196-89, njengokubizwe ngepeyinti eziziintsali zolwelo, ngokuxhomekeka ukumiswa of zombala kunye fillers, amabanjwa eziziintsali zolwelo of iipholima, nelo izinto abangabancedani ezahlukeneyo ezifana njenge emulsifier, somfanekiso kunye ezinye.

GOST 28196-89 ithatha siyishiye GOST 19214-80 no GOST 20833-75, TU 6-10-1260-87 TU 6-10-2031-85 TU 6-10-2054-86 TU 06.10.2081 -86 phezu iipeyinti kunye ivanishi. Zonke neepeyinti yamanzi-eziziintsali ezi engangenwa, kunye nemveliso yazo kunye nokusebenza zinokubakho kuphela kwiindawo ekusetyenzwa umoya.

Ngokutsho GOST, ezothutho kunye nokugcinwa kufuneka yenziwe tarakh evaliweyo kubushushu ngentla 0 degrees, kodwa wavuma ukuba ukwehla ixesha elifutshane lobushushu ukuze degrees -40 inyanga enye.

ipeyinti latex, iinkcukacha banikela iimpawu zayo ukukhanya reflectance, imveliso ubaleka definition lightfastness - icandelo umfuniselo iiyure 24 ibekwe phantsi isibane okhethekileyo, ngoko iiyure 2 mnyama tshu, ze emva koko xa kuthelekiswa iisampuli zeengcali.

Iimpawu kokusetyenziswa kwamanzi-emulsion ipeyinti VEAK

VEAK ipeyinti Amanzi, iinkcukacha ezo omnye kakhulu eziyimfuneko ukulungiselela umsebenzi ekhuselekileyo nekhawulezayo kwisithuba kweendawo zokuhlala; ngokupheleleyo oluhambelana ukulungiswa ekhaya.

Kuyinto emhlophe kunye nesicwangciso ngombala ezongezelelweyo, apho ungafumana nawuphi na umbala oyifunayo.

Kwimeko nganye komhlaba kufuneka zibe mpuluswa ngokupheleleyo kwaye owomileyo - imiqathango ukusetyenziswa VAEK kuya kuba ngaphantsi kwe 150 grams square metre nganye. Kubalulekile kakhulu ukuba kulala phantsi imiphezulu ubudala yaye sele zipeyintwe, kuba sele izikhuseli-based ayomise kwisithuba seeyure-4.

Ekubeni VEAK - ipeyinti latex acrylic, iimpawu yobugcisa ukuvumela ukuxutywa yayo ngamanzi, kodwa hayi ngaphezulu kwe-10 ekhulwini ngalinye umqulu zaseprayimari. Sebenzisa ithinasi imichiza akunakwenzeka. iipropati ipeyinti bavumela ukuba uhlambe iindawo ayiqabe ngamanzi ashushu, kodwa acoce ezi zixhobo kuyo kwangoko kulandela kugqitywe umsebenzi.

Phantsi kweemeko kangangoko, umphezulu zipeyintwe angalahlekelwa umbala kwaye ihlala iminyaka engaphezu 7.

Iimpawu kokusetyenziswa zepeyinti PVA

Efanayo umgangatho nakwikota yokusebenza, kwakunye indlela zokusebenzisa ayinikezi Polyvinyl acetate latex, iinkcukacha zobugcisa ezivumela ukusebenzisa kuyo umbala hayi nje iindawo ngaphakathi kwisakhiwo, kodwa yekhadibhodi, ngamaplanga, drywall neenkuni.

PVA paint ezingatshiyo, kodwa boyika kakhulu yomahluko iqondo lobushushu nokufuma. Le Ipeyinti latex, iimpawu zobugcisa ezenza kube lula ukuyisebenzisa ukuze eyigqibile komhlaba, yaye apho njani na kowomileyo ngokupheleleyo iiyure ezimbini.

Kuselwe PVA emulsion ayinikezi malunga 200 mililitha square metre nganye, ngenxa yokudweba iindawo kufuneka ukuba balisebenzise kwiiseli ezininzi. Inkulu kunezinye iintlobo ze-inki ngesifo kunye nokwakheka ethile kwenza ukuba lixhome kakhulu ixabiso.

iimpawu ezithile ipeyinti latex, "Teks"

Xa ukhetha uhlobo lwemveliso ipeyinti nkampani kufuneka sifumane ingqalelo yayo ipeyinti ngamanzi-based "Tex". It is a silikonomodifitsirovannuyu lulwelo acrylate-based Lubonakala mnandi ayenechaphothi emhlophe viscous, ngokulinganisela kunye nesicelo lula. Kuba wenza uluhlu olupheleleyo abatsali.

ipeyinti latex, "Teks", iinkcukacha zobugcisa ezivumela ukuba ndiyibeke phezu isitena, ikhonkrithi, imiphezulu iinkuni, ezisetyenziselwa ukunyanga wesilingi; it yakha moya kwi umboniso matte elamnce- evumela umoya ukwazi ukuhamba ngokukhululekileyo phakathi Ipeyinti kunye ububanzi izinto komhlaba. Nangona kunjalo, lo luncedo ephambili izicacele ipeyinti "Tex" ke ebushushwini balo ezibuthathaka - umoya egumbini xa usebenzisa yona ukuba ibe kunomzimba +5 degrees Celsius.

Imigaqo ngokubanzi lwemisebenzi yenkathalelo kwakunye ukuhlanjululwa Imiphezulu zigqunywe ngepeyinti ngamanzi-kwiintsali

Nayiphi ipeyinti latex - zihlambeke; iimpawu zobugcisa inki ayikwazi kuphela lula yaye ngokukhawuleza isicelo umbandela kwindawo nkqo okanye tyaba ahambise kunye brush, kodwa ixesha elide ukosula kumphezulu ngelaphu elifumileyo.

Ukuze yokuhlambulula izixhobo zokwakha kunye nempahla ukusuka ipeyinti ezinjalo sele inikezelwe lather (ngokuba zokumiswa Polyvinyl acetate); ipeyinti emulsion acrylic kufuneka kuqala buhlungu spatula - ukususwa isantya nangakumbi kummandla wacela umphezulu zipeyintwe, kuqala ukucola okubonisa ngaphaya kunye iphepha okanye amaphepha, azibeke ke phezu otashi gelatinous okanye abaqhelekileyo lodonga paste.

Coca iinxalenye kumphezulu acrylic mhlawumbi usebenzisa dryer isakhiwo kunye spatula - avuthayo siyinxalenye komhlaba kunye nokususa incakuba yawo.

izinyibilikisi yamachiza nokufuya kokususa ipeyinti ngamanzi-based ngokubonelela imiphumo ngokuthe ngcembe umonakalo, kodwa wenze ivumba elibi kwaye yityhefu eziphilayo.

Eziliqela iingcebiso malunga nokusetyenziswa ipeyinti emanzini

Phambi ukusebenza abaneemfuno paint ngamanzi-based ukuba ilungelelaniswe, ukutyabeka, yaye ukuba kuyimfuneko zashpatlevat zonke iindawo. Nangona ipeyinti eziphilayo, usenalo ukupheka ukuba izibuko, imaski uthuli neeglavu.

Paint Bank izanyazanyiswa, imixholo, ugalelwe kwaye exutywe namanzi ngokwemiyalelo. On udonga zashpatlovannye Ipeyinti isetyenziswe ngeengcamba ezintathu phezu lodonga - omnye. Ipeyinti isicelo ngezithandelo ngaxeshanye ukusuka window ukuya eludongeni. Izixhobo ezisetyenziswa isicelo brush, izileyi, isipreyi kunye spatulas.
