Polyurethane txha hniav laus: txheej txheem cej luam, yam ntxwv, hom, daim ntawv thov

Yuav kom tiv thaiv cov hniav los ntawm tsis zoo influences, xws li huab cua, hnub no yog dav siv polyurethane enamel, uas yog muaj rau cov muag khoom nyob rau hauv ib tug ntau yam. Qhov no sib tov nruab nrab ntau yam polymers muaj teeb meem zog. Yog hais tias ib tug sib piv ntawm no muaj pes tsawg leeg nrog rau lwm cov dyes, lub polyurethane txha hniav laus tsis phim lwm yam embodiment. Heev feem ntau, cov muaj pes tsawg leeg yog siv raws li ib tug tiv thaiv txheej, txij li thaum cov zaj duab xis muaj ib tug high paj tau paj ntawm kev ruaj ntseg.

Ib suam ntawm polyurethane enamels

Lub polyurethane mixtures raug muab faib los ntawm cov ntaub ntawv uas yuav tsum tau them, raws li zoo raws li nyob rau hauv lub hom ntawm daim ntawv thov thiab muaj pes tsawg leeg. Yuav siv tau mus thov ib tug tshwj xeeb txhuam los yog tshuaj tsuag raj mis. Teb ntawm kev siv polyurethane txha hniav laus dav txaus rau ntau hom yuav tau mus thov mus rau ib tug lub pob zeb, ntoo los sis hlau. Ua ntej siv cov polyurethane sib tov ntoo yog tsis yuav tsum tau prime, tab sis nws yuav tsum zoo qhuav.

kev yam ntxwv

Ib-tivthaiv polyurethane txha hniav laus yog ib tug muaj pes tsawg leeg uas yog tsim los ntawm polyurethane, xim thiab kuab. Ntawm cov ntsiab yam ntxwv ntawm cov niam yuav tsum tau tseem ceeb:

• durability;
• elasticity;
• harmlessness tom qab evaporation ntawm cov kuab;
• tshuaj stability.

Polyurethane compositions txig ua raws li cov feem ntau nyuaj chaw.

Ntau hom polyurethane enamels

Polyurethane txha hniav laus tej zaum yuav aqueous dispersion. Ntawm cov zoo yog cov harmlessness rau dyeing theem thiab tau dilution nrog dej dawb. Nws yog tsis haum rau dyeing hydrophobic chaw xws enamels. Qhov no yuav tsum muaj xws li vaj tse, stainless hlau thiab yas.

Polyurethane muaj cov cim tshuaj kev hloov kho uas tso cai rau cov muaj pes tsawg leeg muab cia rau hauv daim ntawv ntawm ib tug aqueous dispersion ntawm ib tug hardening tsis. Qhov no pub rau muaj zog coj-resistant txheej. Yog hais tias tsim nyog, uas tseg tau rau hauv pem teb nyob rau hauv lub chaw ua hauj lwm yog pom zoo kom muab nyiam rau tus yeees ntawm cov organic solvents.

Polyurethane txha hniav laus organic solvents

Polyurethane txha hniav laus yuav ua tau raws li nyob rau hauv cov organic solvents, xws li xylene los yog toluene. Yuav kom zoo dua siv lub xov tooj ntawm dilution kuab tshuaj, uas yog pom zoo los ntawm lub chaw tsim tshuaj paus. Tom qab tua, uas yuav siv sij hawm ob hnub, lub txheej yuav zoo, hu ua lub ntsiab zoo: durability, dej kuj, ua hauj txhoj puab heev media.

Polyurethane xim txha hniav laus lwm yog alkyd-urethane, lawv yog siv los tsim ib qho kev ywj thiab check txheej uas solidifies maj mam, thiab muaj ib tug me me tsw thaum lub sij hawm dyeing. Tus nqi ntawm xws li ib tug sib tov yog ho qis piv mus rau ib tug-tivthaiv urethane enamels.

Hauj lwm ob-tivthaiv polyurethane enamels

Txha hniav laus yog li ntawm ob-feem polyurethane hardener thiab enamel, cov thawj ntawm cov uas yog ntxiv ua ntej yuav siv. Cov sib tov khaws nws cov nqi rau 3 xuab moos, thiab lub qhuav kav 6 teev. Tus nqi ntawm cov khoom no yog high school raws li lub zog ntawm cov txheej. Tej polyurethane txha hniav laus mus hlau yuav raug siv rau hlau yuav tsum tau loaded nyob rau hauv ntau lawm tej yam kev mob thiab nyob rau hauv kub khw ua nrog ib tug txhoj puab heev cua.

Lub sab sauv txwv ntawm cov kev khiav hauj lwm kub ntawm lub sib tov yog +80 ° C thiab yuav ncav cuag ib theem ntawm 100 ° C. Yog hais tias muaj yog ib tug yuav tsum tau them rau cov kev siv, uas yuav siv tau nyob rau hauv hluav taws kub tej yam kev mob, nws yog tsim nyog los yuav tshwj xeeb compositions. Piv txwv li, cov xim muaj hlau rau hlau "Polysteel" thaum raug rau ib tug kub rau tsim ib tug carbon ua npuas ncauj uas securely resists cov nplaim taws thiab lub tshav kub insulating rau 1.5 sij hawm.

Daim ntawv thov ntawm polyurethane txha hniav laus "Elakor-PU"

Yog hais tias koj yuav tsum tau priming txha hniav laus polyurethane, them mloog mus rau lub "Elakor-PU", tus nqi ntawm uas ib kilogram ntawm 275 rubles. Qhov no muaj pes tsawg leeg yuav tsum tau thov nyob rau hauv tej yam tej yam kev mob, uas yog qhia nyob rau hauv lub qhaj ntawv ntawm lub qab ntawm lub capillary dej sawv. Nws yog ib qho tseem ceeb kuj yog cov muaj ntawm lub hauv paus waterproofing. Qhov seem dej nto yuav tsum tsis txhob yuav ntau tshaj li 5%. Ua ntej thov kev nyob tus yeees ntawm qhov chaw twg thiaj li raug rhuav tshem ntawm cov oily chaw. Thaum nws los txog rau lub pob zeb ua lub hauv paus, nws yuav tsum tau sanded nrog ib tug tshwj xeeb lub tshuab los tshem tawm cov remnants ntawm lub qub xim, av thiab laitance.

Ua ntej vaj tse polyurethane txha hniav laus li no, tus nto yuav tsum tau dedusted siv ib tug muaj lub tshuab nqus tsev nqus tsev vacuum, thiab tom qab lub primer cover los ntawm cov tib Chaw tsim tshuaj paus. Ua ntej siv, tus tov yog do zoo, thiab nws yog tsim nyog mus thov ib tug Polyamide menyuam 4 txheej. Qhov tsawg kawg nkaus naj npawb ntawm cov khaubncaws sab nraud povtseg yog 2, qhov kawg tooj yuav nyob ntawm seb raws li qhov lub hom phiaj caum. Nruab nrab ntawm lub khaubncaws sab nraud povtseg yog tsim nyog los tos txog 4-8 teev.

Thov txha hniav laus Qhob "Elakor PU-txha hniav laus-60"

Qhov no txha hniav laus yog ib ya-tua ib-feem xim semigloss sib tov raws li lub ntsiab kom zoo dua ntawm cov uas yog tau daim ntawv thov thaum uas tsis muaj kub. Tom qab lub polymerization, cov khoom tsim coj-resistant yas polymer nto uas yog txawv tshuaj kuj.

Kev npaj thiab purification lus dag nyob rau hauv lub priming nto uas yog coated tom qab tus txha hniav laus ntawm ib tug kub ntawm los ntawm -30 mus +25 ° C. Qhov kub ntawm cov khoom tej zaum yuav txawv ntawm +10 rau +25 ° C. Nws yog ib qho tseem ceeb mus rau hauv kev saib xyuas cov txheeb ze humidity ntawm cov huab cua, nws yuav tsum tsis txhob ntau tshaj 80%. Ua ntej yuav daim ntawv thov cov muaj pes tsawg leeg yog mixed kom txog thaum uniform xim thiab taub hau. Rau no tov khoom yuav siv tau rau cov xim tsev, uas yog ntsia tau rau momentum nyob rau hauv lub chav los ntawm 400 mus 600 ib feeb.

Rau kev ua hauj lwm, koj muaj peev xwm siv chais los yog txhuam, uas yog resistant rau cov kuab tshuaj. Koj muaj peev xwm siv airless tsuag technology. Nyob rau hauv ib txheej, ib cheeb tsam ntawm ib tug square meter, yuav muab kwv yees li 150 g enamel. Qhov kawg tshwm sim yuav nyob ntawm seb lub smoothness ntawm qhov chaw. Stratified kom qhuav kav rau tib lub sij hawm, raws li nyob rau hauv lub saum toj no embodiment.

xaus

Yog hais tias koj txiav txim siab los siv ib ob-tivthaiv polyurethane muaj pes tsawg leeg, peb yuav tsum coj mus rau hauv tus account uas nws cov ntaub ntawv yog tsis nqa tawm nyob rau hauv ntub chaw. Qhov no yuav tsum tau yog vim lub fact tias cov curing neeg sawv cev yuav hnov mob nrog lub kua tso tawm carbon dioxide, uas muaj txhawb rau foaming ntawm qhov chaw.
