China Unsaturated Polyester Resin fakitale ndi opanga

Opanga Unsaturated Polyester Resin

kufotokozera mwachidule:

Utomoni wa 7937 ndi utomoni wa polyester wosaturated wa ortho-phthalic wokhala ndi phthalic anhydride, maleic anhydride ndi ma diols wamba ngati zinthu zazikulu zopangira.
Ili ndi mphamvu zabwino zoteteza madzi, mafuta komanso kutentha kwambiri.

Kulongedza ndi Kusunga

• Chogulitsacho chiyenera kuyikidwa mu chidebe choyera, chouma, chotetezeka komanso chotsekedwa, cholemera 220 Kg.
• Nthawi yosungira zinthu: miyezi 6 pansi pa 25℃, yosungidwa pamalo ozizira komanso abwino.
malo opumira mpweya.
• Ngati mukufuna kulongedza zinthu zapadera, chonde funsani gulu lathu lothandizira

ZINDIKIRANI

• Chidziwitso chonse chomwe chili mu kabukhu aka chimachokera ku mayeso okhazikika a GB/T8237-2005, koma kungogwiritsidwa ntchito; mwina kusiyana ndi deta yeniyeni ya mayeso.
• Pakupanga zinthu zopangidwa ndi utomoni, chifukwa magwiridwe antchito a zinthu zopangidwa ndi utomoni amakhudzidwa ndi zinthu zingapo, ndikofunikira kuti ogwiritsa ntchito adziyese okha asanasankhe ndikugwiritsa ntchito zinthu zopangidwa ndi utomoni.
• Ma resini a polyester osakhuta ndi osakhazikika ndipo ayenera kusungidwa pansi pa 25°C mumthunzi wozizira, kunyamulidwa m'firiji kapena usiku, kupewa kuwala kwa dzuwa.
• Mkhalidwe uliwonse wosayenerera wosungira ndi kunyamula zinthu udzapangitsa kuti nthawi yosungiramo zinthu ichepe.

MALANGIZO

• Utomoni wa 7937 ulibe sera, zowonjezera zowonjezera mphamvu ndi thixotropic.
• Utomoni wa 7937 ndi woyenera kutsukidwa kutentha kwa chipinda ndi kutentha kwapakati. Kutsukidwa kutentha kwapakati kumathandiza kwambiri pakuwongolera kupanga ndi kutsimikizira magwiridwe antchito azinthu. Kulimbikitsidwa pa dongosolo lotsukidwa kutentha kwapakati: tert-butyl peroxide isooctanoate TBPO (zomwe zili ≥97%), 1% ya utomoni; kutentha kwa utomoni, 80±5℃, kutsukidwa osachepera maola 2.5. Chothandizira cholumikizira chovomerezeka: γ-methacryloxypropyl trimethoxysilane KH-570, 2% ya utomoni.
• Utomoni wa 7937 umagwiritsidwa ntchito kwambiri; tikukulangizani kusankha utomoni wa 7982 kapena utomoni wa o-phenylene-neopentyl glycol 7964L wokhala ndi zofunikira pakugwira ntchito bwino; tikukulangizani kusankha m-phenylene-neopentyl glycol 7510 kuti muzitha kupirira madzi ambiri, kutentha komanso kukana nyengo. Utomoni; ngati zipangizozi zikukwaniritsa zofunikira, chonde sankhani utomoni wa isophthalic 7520 wotsika mtengo, womwe ndi wotsika mtengo komanso wogwira ntchito bwino.
• Pakupanga chinthucho, chikatenthedwa ndi kukonzedwa, chiyenera kuchepetsedwa pang'onopang'ono kufika kutentha kwa chipinda, kuti chisazizire mofulumira, kuti chisawonongeke kapena kusweka, makamaka m'nyengo yozizira. Kudula ndi kupukuta miyala ya quartz pakupanga kuyenera kuchitika pambuyo pokonzedwa mokwanira.
• Kuchuluka kwa chinyezi m'chodzaza kuyenera kupewedwa. Kuchuluka kwa chinyezi kudzakhudza kuuma kwa chinthucho ndikupangitsa kuti ntchito yake ichepe.
