Tanthauzo ndi Makhalidwe a Utoto wa Enamel wa Acrylic
Utoto wa enamel wa acrylic ndi mtundu wa utoto pomwe utomoni wa acrylic ndiye chinthu chachikulu chomwe chimapanga filimu. Nthawi zambiri umakhala ndi mphamvu zabwino zotsutsana ndi nyengo, kukana dzimbiri kwa mankhwala, komanso kukongoletsa. Malinga ndi zotsatira zakusaka, utoto wa enamel wa acrylic uli ndi mphamvu zabwino zotsutsana ndi dzimbiri, kusalowa madzi, komanso kukana mafuta, ndipo umatha kuteteza bwino pamwamba pa zinthu kuti zisawonongeke ndi kuwonongeka kwa chilengedwe chakunja. Kuphatikiza apo, monga utoto wa acrylic wa magawo awiri, utoto wa enamel wa acrylic polyurethane umagwiritsa ntchito njira pakati pa -OH ya acrylic ndi -NCO ya polyurethane kuti ilumikizane ndikuchiritsa filimuyo, ndipo imakhala ndi mphamvu zabwino kwambiri zokana kukalamba, kukana kusamba m'madzi, kukana thupi, kukana mitundu, komanso kusunga kuwala.
Kugwira ntchito bwino kwa utoto wa enamel wa acrylic poteteza madzi
- Utoto wa acrylic uli ndi mphamvu zoteteza madzi ndipo ndi woyenera pazochitika zomwe zimafuna dzimbiri ndi kukana madzi, monga zida zopangira zitsulo, milatho, zombo, zitsulo, ziwiya, makina omanga, mitundu yosiyanasiyana ya magalimoto oyendera, ndi zina zotero. Kuphatikiza apo, utoto wa acrylic polyurethane ulinso ndi mphamvu zoteteza madzi ndi kukana alkali, ndipo ndi woyenera mafakitale omwe ali ndi kuwonongeka kwakukulu.
- Enamel ya acrylic (monga utoto wa acrylic magnetic, utoto wa acrylic polyurethane magnetic) imatha kuonedwa ngati mtundu wa utoto wokhala ndi mphamvu zosalowa madzi. Mbali yake yosalowa madzi imapangitsa kuti ikhale yoyenera pazochitika zomwe chitetezo ku kulowa kwa madzi chikufunika, komanso ili ndi zabwino monga kukana dzimbiri ndi kukana ukalamba.
Maziko ofunikira a ntchito yoteteza madzi
Enamel ya acrylic (yomwe imadziwikanso kuti utoto wa acrylic) ili ndi mphamvu zabwino kwambiri zosalowa madzi, ndipo izi zagwiritsidwa ntchito kwambiri komanso zatsimikiziridwa pankhani yolimbana ndi dzimbiri m'mafakitale. Nazi malingaliro atsatanetsatane ogwiritsira ntchito:
Maziko ofunikira a ntchito yoteteza madzi
- Makhalidwe a zinthu
Utoto wa enamel wa acrylic umagwiritsa ntchito utomoni wa acrylic ngati chinthu chachikulu chopangira filimu. Kapangidwe kake ka molekyulu kamakhala ndi mphamvu zotsutsana ndi madzi, ndipo pambuyo pouma, kamatha kupanga filimu yolimba komanso yopitilira, zomwe zimathandiza kupewa kulowa kwa madzi. Zinthu zina zimawonjezeranso zinthu zosinthidwa za chlorosulfonated polyethylene kapena polyurethane (monga utoto wa acrylic polyurethane magnetic), zomwe zimawonjezera kukana madzi komanso kuteteza chinyezi.
Mwachitsanzo, emulsion ya acrylic yochokera m'madzi kudzera mu kapangidwe kapadera ka gulu losawopa madzi imatha kuletsa mamolekyu a madzi kulowa mu substrate ikauma.
Zinthu zopangidwa ndi zosungunulira (monga utoto wa acrylic metal magnetic) zimakhala ndi mphamvu yolimbana ndi madzi ndipo ndizoyenera malo okhala ndi chinyezi kwa nthawi yayitali.
- Kutsimikizira magwiridwe antchito
Mayeso a labotale asonyeza kuti utoto wa enamel wa acrylic ukakhala utanyowa kwa maola 24, sukhala ndi vuto loti ukhale wofooka kapena wogwa pamwamba.
Mu ntchito zakunja (monga milatho, zombo, ndi zomangamanga zachitsulo), ntchito yake yosalowa madzi imatha kuletsa kuwonongeka kwa madzi amvula ndi madzi a m'nyanja, motero imakulitsa moyo wa substrate.
