Water kupenda: nokurondedzerwa, vagadziri, akafanana

Industrial uye unyanzvi kupenda masvingo, ceilings, uriri nzvimbo, midziyo mairi, uyewo hwindo uye musuo mazano kazhinji kushandisa pendi kwakavakirwa ane aqueous emulsion. Latex kupenda, ari hwokugadzira unhu kuti vanopa hurukuro nemishonga uye yepamusoro ruvara, mhoro dzokushandisa michina yemberi uye hakuna chepfu zvinosuruvarisa zvipenyu.

Misimboti inotungamirwa rokudzivirira murwiyo mvura-inobva pendi

Title latex (imwe aqueous akapararira) anozodza imhaka pamberi racho mvura-inobva ruvara slurry pamwe pokubatana emulsion. Vakapararira zvinhu zviri hwakakanyiwa ane aqueous unosvikirwa, uye vakasikwa uye zviripo zvakafanana nayo.

Saka latex unotora munhu filler, mumwe thickener, uye latex akambozvishandisa kuuraya utachiona.

The polymer nezvimedu pashure mvura yaoma panyika vanoumba sandarara kolirovanny rukoko. Undried pendi inogona nyore kubviswa manually, uye ayo rukoko hakuna hachifadzi kwakanaka. Kupenda husingakwanisi zvokuimba kwechirwere, asi haisi kureva simbi hukawanika kudzivirira ngura pamusoro pamberi kugara mwando.

The chikuru hwokugadzira unhu mvura-inobva pendi

Latex kupenda, ari hwokugadzira zvechadenga iyo - the viscosity, ichiyerera zvazvingava, chaiyo giravhiti uye nguva nokuomesa, ane yakatsiga kugadzirwa waivako, Zvakanakisa wakanyatsokodzera nekuda pakurapa dzomunyika hukawanika yokugara musha.

The mwero dilution of dhayi gobvu nemvura akati indekisi viscosity kunoyerwa vachishandisa rheometer.

Yerera mwero emulsion pendi kunoenderana absorbency pakati kugamuchirwa nomumativi ari kubva 100 kusvika 200 Rine mamiririta muzana mativi mutinhimira pamusoro pemvura, ingi ruvara rukoko ndomumwe millimeter gobvu.

Dzakananga kurema latex pendi anenge 1,3 makirogiramu por fő.

Kupwa nguva latex pendi zvinoenderana mwando tembiricha, kubvira maawa maviri kusvikira zuva rimwe. Optimum ezvinhu vaiona kuomesa mhepo tembiricha madhigirii 20 Celsius uye 65% mwando.

The pasherefu upenyu ari emulsion pendi zvikurukuru novimba ayo okuchengetera ezvinhu (mu dzakanakira - akadzikama rima panzvimbo), pamwe neavhareji 24 mwedzi.

Details remvura-kupararira ingi kunooneka zvizere mashoko GOST 28196-89.

Magadzirirwo GOST

Latex, nokurondedzerwa (GOST) ayo vakanyorwa pasi nhamba 28196-89, zvinonzi zita muna aqueous vakapararira kupenda, akapa suspensions ose pigments uye fillers, vasungwa vari aqueous vakapararira chakaita zvokugadzirwa Polymers, izvo akawedzera siyana ebetsero zvinhu zvakadai somunhu emulsifier, stabilizer uye zvimwe.

GOST 28196-89 unotsiva nderechinyakare GOST 19214-80 uye GOST 20833-75, TU 6-10-1260-87 TU 6-10-2031-85 TU 6-10-2054-86 TU 06.10.2081 -86 pamusoro pendi uye varnishes. All pendi mvura-vakapararira vari fireproof, uye kugadzirwa dzavo uye kushanda zvinogoneka chete mune nzvimbo kumanikidzwa-ventilated.

Maererano GOST, chokufambisa dzavo uye okuchengetera zvinofanira kuitwa rakanamwa tarakh panguva tembiricha pamusoro 0 madhigirii, asi ari wakatendera pfupi ichidonhedzera tembiricha kuti -40 madhigirii kuti mwedzi mumwe.

Latex kupenda, nokurondedzerwa vakapa ayo chiedza reflectance ehupfumi, kugadzirwa anofambisa tsanangudzo lightfastness - chidimbu experimental maawa 24 anoiswa pasi chaiyo rambi, tevere 2 maawa zvachose rima, uye ipapo ichienzaniswa ivhu nyanzvi.

Zvakakurukurwa kushandisa mvura-emulsion pendi VEAK

Water kupenda VEAK, nokurondedzerwa zviri chimwe chezvinhu zvikuru zvakakodzera kuti yakachengeteka uye nokukurumidza basa nzvimbo yokugara kwakavakirwa, optimally wakanyatsokodzera musha igadziridzwe.

Zviri chena uye iine yakawedzerwa pigments, yauchaita kuwana chero achida ruvara.

Muchiitiko chimwe nechimwe pemvura anofanira kumeso zvakakwana uye yakaoma - zvinhu zvakadai VAEK kuparadzwa richava magiramu asingasviki 150 paminiti mativi mita. Hazvina kunaka kuti arare pasi kare uye kare kupendwa hukawanika, nokuti ane latex nezveBhaibheri uye unoomesa mukati 4 maawa.

Sezvo VEAK - acrylic latex kupenda, ari hwokugadzira unhu kubvumira dilution ayo nemvura, asi kwete kupfuura 10 muzana chezvinhu vhoriyamu. Shandisa zvine makemikari thinners hazvibviri. Pendi wacho ehupfumi kubvumira kuti kugeza vakarondedzera hukawanika nemvura inodziya, asi kuchenesa zvokushandisa kubva pakarepo inotevedzera kuvakwa basa.

Under optimum ezvinhu, mashoko vakarondedzera pamusoro havazotadzi ruvara uye mukurumari kwemakore anopfuura 7 kwemakore.

Zvakakurukurwa kushandiswa PVA pendi

Zvakafanana unhu uye izwi kushanda, uyewo mashandiro kwokushandisa pendi iri polyvinyl acetate latex, hwokugadzira nokurondedzerwa hunoita kuti kurishandisa noruvara kwete chete dzomunyika hukawanika hworusvingo, asiwo makadhibhokisi, plywood, Drywall nehuni.

PVA pendi moto nemishonga, asi vakatya zvikuru pamusoro tembiricha musiyano uye mwando. Izvi latex kupenda, ari hwokugadzira unhu izvo zvinoita kurishandisa ndakapedza pamusoro, uye iro riri yaoma kwemaawa maviri.

Kudyiwa PVA emulsion pendi anenge 200 milliliters por mativi meter, nokuti kupenda kuti mavara vanofanira kuzvishandisa akawanda akaturikidzana. Kupfuura dzimwe mhando ingi zvinodyiwa uye yakananga nziyo anoita zvakawanda izvozvo zvinodhura kuti kukosha.

Dzinenge zviri latex kupenda, "teks"

Pakusarudza rudzi pendi chigadzirwa uye kambani kunofanira tiswedere ayo pfungwa mvura-kwakavakirwa pendi "Tex". Zviri viscous mvura silikonomodifitsirovannuyu acrylate-kwakavakirwa zvizere Crisp chena kubwinya, kunwa zvine uye chikumbiro nyore. Nokuti akaita zvizere zvakawanda callers.

Latex kupenda, "teks", hwokugadzira nokurondedzerwa hunoita kuti ndokuriisa zvidhina, kongiri, matanda hukawanika, kushandiswa pakurapa masvingo uye ceilings; anoumba ndege iri rinoshanda matte firimu kuti anobvumira mhepo kutenderedza pachena pakati pendi uye pakukora pemvura zvinhu. Zvisinei, chikuru uye pachena zvakaipira pendi "Tex" raro vasanonoka kupisa - mhepo mumba kana ukashandisa kuti dzinodziya pane +5 Celsius.

General Misimboti hanya uye kucheneswa hukawanika akafukidza mvura-vakapararira pendi

Chero latex pendi - wachika; Technical zvechadenga ingi haagoni chete nyore uye nokukurumidza kureva zvinhu pamusoro kutwasuka kana zvido zvevanhu pose chinotenderera uye mumakwenzi, asi zvino kwenguva refu kutsakatisa pemvura ane nyorova jira.

Kuchenesa chivako maturusi uye zvipfeko kubva pendi kwakadaro rinoshandiswawo lather (nokuti polyvinyl acetate suspensions); acrylic emulsion pendi anofanira kutanga kurwadzisa spatula - nokuti mukuru kukurumidza nokubviswa achida nzvimbo yacho kupendwa pamusoro, tanga namatidza pamusoro pepa kana mapepa, ngaazviise pamusoro gelatinous starch kana munhuwo Wallpaper namatidza.

Wachenesa zvikamu pemvura acrylic zvichida uchishandisa chivako Dryer uye spatula - kutsva zvimedu pemvura uye nokubvisa reza dzavo.

Chemical zvokufembedzwa tiri akakodzera kubvisa mvura-inobva pendi nokupa zvishoma nezvishoma kukuvadza, asi ivo emit risingafadzi kwakanaka uye muchetura kuti muviri.

Vakawanda kunenge pakushandisa utachiona pendi

Asati kushanda nemvura anotsanangura pendi zvinodiwa kuti dzichienderana, plaster, uye kana zvakakodzera zashpatlevat hukawanika zvose. Pasinei zvipenyu nezvakazvipoteredza pendi, iwe uchiri bikai kuti magogorosi, mumwe guruva chifukidzo uye magiravhusi.

Kupenda Bank zvinozununguka, zviri hwakakanyiwa uye rakasanganiswa nemvura maererano nemirayiridzo. On rusvingo zashpatlovannye pendi rinoshandisirwa matatu akaturikidzana pamusoro Wallpaper - mumwe. Pendi iri kushandiswa zvakafanana micheka nepahwindo pamadziro. Zviridzwa akashandiswa chikumbiro mumakwenzi, rollers, bhurandi uye spatulas.
