Polyurethane enamel: zvayakaita, unhu, mifananidzo, kushanda

Kudzivirira hukawanika kubva kunaka zvinofurira, kusanganisira mamiriro okunze, nhasi rinoshandiswa nevakawanda polyurethane enamel, chakabayirwa kutengeswa muna zvakawanda. muvhenganiswa ichi chinomiririra Polymers siyana kuva chipingamupinyi ehupfumi. Kana tikaenzanisa sezvamunoita izvozvi nevamwe madhayi, kuti polyurethane enamel tadza kuwirirana mumwe musimboti. Kazhinji, murwiyo rinoshandiswa senzira unodzivirira unhani, sezvo firimu ine mukuru kumucheto yakachengeteka.

Kupatsanura pakati polyurethane enamels

The polyurethane wemisanganiswa vakakamurwa mashoko akafukidzwa, uyewo pamusoro mhando chikumbiro uye sezvamunoita. Inogona kushandiswa kushandisa rinokosha mumakwenzi kana pfapfaidzo bhodhoro. Munda kushandiswa polyurethane enamel yakafara zvakakwana mhando dzakasiyana zvinogona kushandiswa ibwe, matanda kana simbi. Asati kushandisa polyurethane musanganiswa matanda anoiswa havadikanwi kuti mukuru, asi zvinofanira zvakanaka yaoma.

rwokugadzira unhu

Mumwe-chikamu polyurethane enamel chinhu sezvamunoita yakaitwa kubva polyurethane, ruvara uye solvent. Pakati huru zvechadenga blends zvinofanira pachena:

• mukurumari;
• elasticity;
• harmlessness pashure kwemvura yacho solvent;
• makemikari pakusimba.

Polyurethane nziyo zvakakwana vanoomerera akaoma zvikuru hukawanika.

Siyana polyurethane enamels

Polyurethane enamel kungava aqueous kupararira. Pakati zvazvakanakira ndivo harmlessness pamusoro värjäys mudariro uye nomukana dilution pamwe pachena mvura. Hazvina rwoshandiswa kudhaya hydrophobic hukawanika enamels akadaro. Izvi zvinofanira kusanganisira kongiri, Stainless simbi uye epurasitiki.

Polyurethane rine rakasiyana zvemakemikari nadzurudzo runovabvumira murwiyo mumabhatiri chakafanana aqueous yokupararira imwe nokuomesa kwete. Izvi rinobvumira simba kusakara nemishonga unhani. Kana zvakakodzera, staining pasi kumabasa inokurudzirwa kupa zvinodiwa kuti Zvinoumba zvinoita zvokufembedzwa.

Polyurethane enamel zvinoita zvokufembedzwa

Polyurethane enamel kunogona kuitwa pachishandiswa makemikari zvokufembedzwa, zvakadai xylene kana toluene. Kushandisa nani uwandu dilution zvokufembedzwa, izvo ndakarumbidzwa ari mugadziri. Pashure achirapa, zvinotora mazuva maviri, ari unhani inova quality, akadana chikuru zvazvakanakira: mukurumari, mvura nemishonga, kuramba hasha vezvenhau.

Polyurethane pendi enamel mumwe vari alkyd-urethane, vari kushandiswa pave kwakavharwa nenyama uye rakasimba unhani izvo solidifies zvishoma nezvishoma, uye ane munyoro kwakanaka panguva värjäys. Mutengo musanganiswa akadaro zviri kudzika zvichienzaniswa kune imwe-chikamu urethane enamels.

Description maviri-chikamu polyurethane enamels

Enamel rinoumbwa maviri-chikamu polyurethane hardener uye enamel, okutanga uko akawedzera pamberi kushandiswa. Musanganiswa anoramba chinhanho raro kwemaawa 3, uye kuomesa runogara maawa 6. Mari iyi iri kumusoro sezvo nesimba unhani. Kwakadaro polyurethane enamel kuti simbi kungashandiswa simbi kuti akatakura pasi kugadzirwa ezvinhu uye inopisa zvitoro wakashanda pamwe hwehasha mhepo.

Yokumusoro panogumira uchishandisa kudziya musanganiswa iri +80 ° C uye anogona kusvika pamwero 100 ° C. Kana pane vanoda rinofukidza kuvaka, izvo zvichashandiswa mukunamata moto ezvinhu, zvakakodzera kutenga chaiwo nziyo. Somuenzaniso, kuti pendi iri simbi "Polysteel" kana apindwa tembiricha kuti vaumbe kabhoni furo iyo makachengeteka anodzivisa rimi uye kupisa insulating kuti maawa 1.5.

Kushandiswa polyurethane enamel "Elakor-PU"

Kana iwe zvinoda priming enamel polyurethane, kuteerera "Elakor-PU", kukosha iyo paminiti kilogram kuti 275 rubles. sezvamunoita izvozvi zvinofanira kuiswa pasi zvimwe zvinhu, varehwa pasina pasi rirambe richibvira mvura vanomutswa. Zvinokoshawo zvakare pamberi nechepasi mvura. Residual mwando pamusoro hakufaniri anopfuura 5%. Asati kushandisa Kuronga pamusoro akaora kuparadza jikichira nzvimbo. Kana totaura chesamende hwaro, inofanira sanded chaiwo muchina kubvisa vakasara yekare pendi, tsvina uye laitance.

kongiri polyurethane enamel ari pamberi zvikashandiswa, pose dzinofanira dedusted kushandisa muindasitiri vacuum, uye mushure lähikuva butiro kubva chete mugadziri. Asati kushandiswa, musanganiswa ichibvongodzwa zvakanaka, uye zvakafanira kuti kushandisa polyamide chinotenderera 4 rukoko. Shoma Kuwanda akaturikidzana ndiyo 2, chokupedzisira nhamba kuchaenderana pamusoro zvinangwa vakatevera. Pakati akaturikidzana zvakafanira kumirira maawa anenge 4-8.

Kushandisa enamel Concrete "Elakor PU-Enamel-60"

enamel uyu unyoro-achirapa mumwe-chikamu ruvara semigloss muvhenganiswa sezvo huru mukana unova mukana chikumbiro yakaderera tembiricha. Mushure polymerization, yakasimba aumba kusakara nemishonga epurasitiki polymer pamusoro riri yakasiyana namakemikari nemishonga.

Kugadzirira uye yokuzvinatsa iri priming pamusoro riri zvemapuranga mushure enamel ari tembiricha inobva -30 kusvika +25 ° C. The tembiricha mashoko dzinosiyana +10 kusvika +25 ° C. Zvakakosha kuti kufunga hama mwando dzedenga, inofanira haapfuuri 80%. Asati chikumbiro murwiyo riri yakavhenganiswa kusvikira dzakafanana ruvara uye kusachinja-chinja. Nokuti ichi chisanganiso inogona kushandiswa pendi, iyo yakaiswa pa tichimhanya iri kuwanda kubva 400 600 paminiti.

Nokuti basa, unogona kushandisa rollers kana brushes, izvo husingakwanisi zvokufembedzwa. Unogona kushandisa airless pfapfaidzo michina. Mune imwe layer imwe nzvimbo ine mativi meter, achatora vanenge 150 d enamel. Kwokupedzisira mugumisiro achavaponesa kumeso pemvura. Stratified nokuomesa kunotora zvakafanana nguva, sezvo ari pamusoro musimboti.

mhedziso

Kana ukasarudza kushandisa maviri chinoumba polyurethane sezvamunoita, tinofanira kufunga kuti chikumbiro chayo haina kuitwa pamusoro nyoro hukawanika. Izvi imhaka yokuti okurapa mumiririri achaita sei pamwe nemvura kusunungurwa carbon dioxide, izvo zvinoita kuti anopupuma pamusoro pemvura.
