Kupopera kwa epoxy ndi chophimba cha Halar

I. Kodi chophimba cha epoxy spray ndi chiyani?

Chophimba cha epoxy spray ndi chophimba cha magawo awiri chokhala ndi epoxy resin ngati chinthu chachikulu chopangira filimu. Chimagwiritsidwa ntchito pamwamba pa chitsulo popopera kapena kutsuka kuti chipange gawo loteteza. Chimadziwika ndi kumatira mwamphamvu komanso kukana bwino ku cathodic peel. Chophimba chimodzi chimatha kupanga chomangira chokhuthala (mpaka ma microns 1250) popanda kugwa. Chimachiritsidwa kutentha kwa chipinda ndipo n'chosavuta kupanga. Chophimba cha epoxy ndi choyenera kuteteza kukokoloka ndi dzimbiri kwa mapaipi, zotengera, mapampu ndi ma valve ndi zida zina, ndipo kutentha kwa ntchito nthawi zambiri kumatha kufika pafupifupi 120°C.

II. Kodi chophimba cha Halar n'chiyani?

Halar ndi dzina la malonda la ECTFE (ethylene-chlorotrifluoroethylene copolymer) fluoropolymer powder coating, yomwe ndi chinthu chokhala ndi fluorine yogwira ntchito kwambiri. Imayikidwa pamwamba pa zitsulo pogwiritsa ntchito njira yopopera yamagetsi, ndi malo osungunuka pakati pa 220-245°C ndi kutentha kwakukulu kogwiritsidwa ntchito kosalekeza kwa 150°C.

III.Kodi pali kusiyana kotani pakati pa kukana dzimbiri kwa mankhwala pakati pa ziwirizi?

Zophimba za Halar zimakhala zodzaza komanso zapamwamba kwambiri pakulimbana ndi mankhwala. Zimatha kupirira pafupifupi ma asidi onse amphamvu, maziko olimba ndi zosungunulira za oZrganic zokhala ndi pH ya 1-14. Zitha kunyowa nthawi zonse mu mankhwala oopsa monga 98% sulfuric acid yokhazikika ndi 37% hydrochloric acid pa 121°C kwa masiku 30. Kusintha kwa kulemera kwa zophimba kumakhala kochepera 1% ndipo mawonekedwe a makina alibe kusintha kwakukulu. Zili ndi hydrophobicity yabwino kwambiri komanso kukana kulowa, zomwe zimatha kuletsa bwino zinthu zowononga kuti zisalowe mu zophimbazo ndikufika pansi pa chitsulo. Ngakhale zophimba za epoxy zilinso ndi kukana kwabwino kwa mankhwala, kuthekera kwawo kupirira ma asidi amphamvu (monga sulfuric acid, hydrochloric acid) ndi kutentha kwambiri ndi kofooka kwambiri kuposa zophimba za Halar.

IV.Ndi iti yomwe ili bwino pankhani ya magwiridwe antchito ndi kulimba kwa pamwamba?

Pamwamba pa chophimba cha Halar ndi chosalala kwambiri (Ra yolimba kwambiri ndi pafupifupi 22nm yokha), zomwe ndi zabwino kwambiri kuposa chophimba cha epoxy. Pamwamba pake posalalapo pamatha kuletsa kumatirira ndi kusonkhanitsa tinthu tating'onoting'ono ndi mchere wachitsulo, kuchepetsa mapangidwe a biofilm, kuchepetsa chiopsezo cha mabowo a pinhole, ndikuwonjezera kudalirika kwa anti-crosion. Kuphatikiza apo, chophimba cha Halar ndi cholimba, cholimba komanso cholimba, komanso cholimba ndi UV, kotero sichidzazimiririka kapena kuzimiririka chikagwiritsidwa ntchito panja.

V. Kodi mungasankhe bwanji njira yoyenera yophikira?

Ndikofunikira kusankha chophimba cha Halar pamene——

1. Kukhudzana ndi asidi wamphamvu, alkali wamphamvu kapena mankhwala osakaniza owononga;

2. Kutentha kwa ntchito kumapitirira 120℃ (pazipita 150℃);

3. Malo akunja kapena amphamvu a ultraviolet;

4. Pamafunika malo osalala kwambiri kuti tinthu tisakhale tolimba;

Ndikofunikira kusankha epoxy glaze pazochitika zotsatirazi:

1. Malo osalowerera kapena owononga pang'ono, kutentha kochepera 120°C;

2. Nthawi yomanga ndi yochepa ndipo imafuna kukonzedwa mwachangu;

3. Kulamulira mtengo ndi kokhwima kwambiri.

VI.Mapeto

Malingaliro a kampani Tianjin Tanggu Water-Seal Valve Co., Ltdali ndi gulu la akatswiri aukadaulo lomwe lingathe kupanga zinthu mwalusomavavu a gulugufe, mavavu a chipata, ma valve owunikirandi zinthu zina zama valavu malinga ndi momwe mumagwirira ntchito, ndipo timapereka njira zopopera zomwe zimakwaniritsa zofunikira zinazake zotsutsana ndi dzimbiri. Kaya ndi kupopera kwa epoxy kapena Halar, titha kusankha zipangizo molondola ndikuzipanga mwasayansi kuti titsimikizire kuti valavuyo ikhalabe yokhazikika komanso yodalirika m'malo ovuta. Takulandirani kuti mupereke zofunikira zanu zogwirira ntchito, ndipo tidzakupangirani njira yapadera yophatikizira valavu ndi zokutira.
