Acrylic plaster ua kev zoo siab 50 xyoo ntawm kev siv hluav taws xob. Cov ntsiab lus ntawm kev kho kom zoo nkauj sab hauv nrog imitation ntawm ntuj gypsum thiab ornamental pob zeb yog siv los ntawm builders thiab designers.

Cov thev naus laus zis tsis sib xws yuav tso cai rau koj los npaj koj tus kheej kev lag luam rau kev tsim cov qhov muag pom thiab muaj txiaj ntsig gizmos rau cov tsev nyob thiab fashionistas. Lub extraction ntawm ornamental pob zeb yog tswj los ntawm lub xeev. Cov yas ntim nrog cov xim muab tshuaj txhuam thiab cov hmoov av crushed pob zeb yuav tsim cov khoom siv los ntawm cov khoom muaj nqis roob.

Initial information

Lwm lub npe uas qhia meej meej txog qhov muaj pes tsawg leeg ntawm acrylic gypsum yog plasticrite. Vim tias nws muaj cov khoom ntawm cov khoom siv dag zog - MMA thiab PMMA polymers.

Patented los ntawm PMMA 90 xyoo dhau los. Nyob rau hauv lub neej txhua hnub, lub polymer hu ua organic iav. Cov khoom siv dag zog gypsum yog acrylic resins thiab dej. Cov dej muaj pes tsawg leeg ntawm acrylic resins thiab hmoov yog hu ua txias curing resin. Tsis tas yuav tsum muaj cua sov los tsim cov khoom lag luam.

Feedstock - monomers, belongs rau cov khoom ntawm chav kawm thib peb ntawm kev phom sij rau ib puag ncig. Tab sis tom qab ua tiav cov txheej txheem polymerization hauv cov khoom acrylicTsis pub dawb monomer tsis pom, yog li kev ua tiav ntawm acrylic plaster muaj kev nyab xeeb rau tib neeg.

Kev txiav txim siab ntawm qhov zoo

Lub fragility ntawm cov khoom ua los ntawm cov ntaub ntawv ntuj yog qhia los ntawm lub qhov hws. Cov khoom ua los ntawm ntuj gypsum shrink. Alabaster dries instantly.

Acrylic gypsum yog deprived ntawm cov shortcomings:

• txheej txheem polymerization txuas ntxiv mus dhau sijhawm;
• tsis shrinkage ntawm ornamental khoom;
• tsis muaj kev pheej hmoo ntawm npuas thaum molding.

Cov khw muag khoom kho vajtse hauv lub tebchaws muab cov neeg siv khoom acrylic gypsum Ecoresin simil ceramica, uas hauv Lavxias yog luv rau lub npe "Ecoresin". Cov khoom siv thev naus laus zis rau needlework. Cov hmoov yog tov nrog dej hauv kev faib ua feem raws li cov lus qhia. Koj yuav tsum sib tov rau ob feeb. Tom qab ntawd ncuav qhov sib tov rau hauv molding silicone ntim thiab tshem tawm tom qab ib teev. Tsis tas li ntawd, qhov tiav casting tuaj yeem coated nrog cov xim thiab cov kua roj vanish. Cov thev naus laus zis yog tsim los ua khoom plig, vases thiab cov vaj huam sib luag zoo nkauj.

xov tshuaj part

Acrylic loj rau kev tsim cov khoom siv kho kom zoo nkauj yog tsim los ntawm ob lossis peb yam:

1. Polymer hmoov thiab dej.

2. Acrylic resin, tsis muaj xim thiab tawv tawv.

Txhawm rau txhim kho cov khoom zoo nkauj ntawm gypsum thiab tiv thaiv kom tsis txhob ya raws, acrylic lacquer rau gypsum pab. Cov zaj duab xis tiv thaiv lacquer tsis warp los yog tev tawm vim qhov kub thiab txias. Lub hnub rays tsis rhuav tshem cov txheej thiab cov khoom.

Muas ntau cov txheej txheem -"chemical" tsis hnov tsw vim evaporation ntawm cov khoom. Acrylic lacquer tsis muaj ntxhiab tsw.

Cov khoom siv rau qhov chaw qhuav hauv feeb, qhov ziab nrawm yog cuam tshuam nrog qhov kub thiab txias ntawm huab cua. Tab sis muaj ib tug nuance. Acrylic dej-raws li cov kua roj vanish pib lo tom qab ib pliag. Yog li ntawd, nws yog qhov zoo dua los siv polyurethane varnishes rau gypsum khoom.

Daim ntawv thov

Nyob rau hauv lub tebchaws uas lub caij ntuj no kav 6-7 lub hlis, kev siv cov te-resistant thiab noo noo-resistant acrylic gypsum yog tsim nyog thiab tsim nyog rau kev ua tiav cov phab ntsa sab nrauv ntawm cov tsev.

Tab sis rau kev kho kom zoo nkauj sab hauv, cov vuas luaj, qab nthab rosettes thiab acrylic plaster fittings yog siv tau.

Rau cov kws ua haujlwm hauv tsev

Ua-nws-koj tus kheej acrylic gypsum tuaj yeem kneaded los ntawm tus neeg uas muaj kev tsim tsev tsawg tsawg.

Kev npaj pib nrog huab cua kub hauv qhov chaw ua haujlwm. Raws li cov qauv kev huv hauv cov ntim ntau lawm, cov ntsuas ntsuas ntsuas qhov ntsuas tau zoo yog ntxiv rau 15 ° C. Hla qhov txwv no txo cov polymerization tus nqi exponentially. Piv txwv li, 5-degree poob yuav nce lub sijhawm tos rau cov khoom tiav los ntawm tsib zaug.

Cov dej noo ntau dhau ua rau cov txheej txheem polymerization, ua kom lub sijhawm ua noj thiab kho cov xim ntawm cov khoom npaj. Ua ntej kneading, lub Cheebtsam yog qhuav yam tsis muaj cua sov rau ntawm ib tug qhuav board ntawm ntuj ntoo los yog nyob rau hauv daim ntawv huv si. Lub tshuab ziab khaub ncaws yuav tsum tsis txhob muab tso rau ntawm lub tshuab hluav taws xob lossis hauv qhov cub.

Muaj peev xwm sau cov khoom sib xyaw hu ua matrix. Txhawm rau tiv thaiv cov khoom pib los ntawm kev nplaum, qhov chaw ua haujlwm ntawm cov khoom molding yog lubricated nrog tus neeg sawv cev cais.

Acrylic gypsum yog kneaded nyob rau hauv lub thawv yas. Ua ntej, cov resin yog poured rau hauv lub thawv, ces cov polymer yog poured.

Nws yog qhov teeb meem ntawm proportionality

Ntawm no yog qhov muaj txiaj ntsig los ua raws li kev faib ua feem. Tsis pub ntsuas qhov muag.

Cia tag nrho cov teeb ua 10 qhov chaw: 7 qhov chaw ntawm cov resin thiab 3 qhov chaw ntawm hmoov. Qhov piv rau kev npaj thawj zaug: 6 qhov chaw cob thiab 3 qhov chaw hmoov. Maj mam thiab meej sib tov, ua tiav qhov sib xws ntawm "zoo li ntawm pancakes - tsis muaj pob." Lub sijhawm tos kom tiav cov hmoov nkag mus rau hauv cov resin yog muab sib npaug rau ib teev, yog tias qhov kub ntawm qhov chaw ua haujlwm yog xis nyob.

Tam sim no yog lub sijhawm los siv cov khoom pov tseg xya ntawm cov resin; lub hardener yog ntxiv rau cov khoom hauv ib lub thawv cais; mix, tos kom tiav dissolution ntawm hardener thiab ntxiv rau cov npaj tov.

Proportions in kilograms:

• 1,8 kg ntawm resin.
• 0.9kg acrylic hmoov.
• Qhov hnyav ntawm qhov npaj muaj pes tsawg leeg yog 2.7 kg.
• Cov tawv tawv siv 2% ntawm qhov hnyav ntawm qhov sib xyaw ua tiav - 2.7 kg2%=54 grams.

Ncuav 300 grams ntawm residue rau hauv ib lub thawv yas cais, ntxiv 54 grams hardener. Los ntawm kev co, lub hardener yog ntseeg kom yaj yam tsis muaj residue. Qhov tshwm sim 354 grams ntawm qhov sib tov yog nchuav rau hauv cov tshuaj npaj thiab sib tov.

Kev ua yuav tsum ceev. Nyob rau hauv ib qho chaw sov so, polymerization yuav ua tiav nyob rau hauv ib nrab ib teev. Yog hais tias cov khoom yog meant xim, ces muab tshuaj txhuam yog tovxav xim. Txhawm rau kom tsis txhob muaj cov nyhuv ntawm cov yas, ntxuav dej xuab zeb, cov pob zeb marble yog ntxiv rau cov pwm molding; aluminium hmoov los yog crushed pob zeb ntawm cov feem me me.

Cov khoom ntawm cov qauv me me thaum kawg yuav tawv hauv 2 teev tom qab nchuav cov sib tov rau hauv lub thawv molding. Zuag qhia tag nrho cov vuas, countertops thiab kab "qhuav" rau ib hnub.

Kev nyab xeeb

Ua ntej pib ua haujlwm, xyuas kom lub qhov cua ntawm chav. Muab cov khaub ncaws paj rwb. Siv kev tiv thaiv: ntawm tes - hnab looj tes roj hmab, ntawm qhov muag - tsom iav zoo li cov neeg ua luam dej, ntawm qhov ntswg thiab qhov ncauj - lub tshuab ua pa. Muab cov hnab looj tes pov tseg thaum koj ua tiav, vim kev ntxhua khaub ncaws kim dua. Yog tias cov iav tsis tiv thaiv cov khoom ntawm acrylic plaster kom nkag mus rau hauv lub qhov muag, koj yuav tsum tawm ntawm qhov kev sib tham thiab tam sim ntawd yaug koj ob lub qhov muag hauv dej ntws tsawg kawg 15 feeb.

Cov khoom siv xoob thiab kua yog khaws cia hauv cov thawv ntim cua nrog lub hau kaw ntom nti. Yog tias tus kws tsim khoom hauv tsev yuav cov khoom siv hauv ib pob thiab tsis siv cov khoom siv 100%, ces cov khoom seem tuaj yeem khaws cia rau ntawm lub sam thiaj lossis hauv chav nres tsheb rau 12 lub hlis. Resin tolerates Ural frosts. Tsis tas yuav khaws cov khoom siv hauv qhov chaw nyob.

Qhov thib ob ntawm acrylic gypsum - lub hardener - ignites. Yog li ntawd, cov khoom yuav cia txias thiab noo.

Ua raws li cov cai yooj yim thiab nkag siab tau yuav pab koj muaj kev lom zem thaum koj lub sijhawm dawb ua cov khoom sab hauv los ntawm cov khoom siv plaster.
