Kagwiritsidwe Ntchito
Hexahydrophthalic anhydride (HHPA) ndi chinthu chofunikira kwambiri chomwe chimagwiritsidwa ntchito kwambiri:
- Mu gawo la zophimba: Zingagwiritsidwe ntchito pokonzekera ma resini osiyanasiyana a polyester ogwira ntchito kwambiri. Zophimba zopangidwa kuchokera ku ma resini amenewa zimakhala ndi zomatira zabwino kwambiri, kukana dzimbiri, komanso kuuma. Mu zophimba zoteteza mafakitale ndi ma topcoat a magalimoto, kugwiritsa ntchito ma resini a polyester okhala ndi hexahydrophthalic anhydride sikungoletsa kuwonongeka kwa ma acid akunja, alkalis, ndi zosungunulira komanso kusunga kuwala ndi umphumphu wa zophimbazo kwa nthawi yayitali, kupereka chitetezo cha nthawi yayitali pazinthu zophimbidwa.
- Ponena za zipangizo zamagetsi ndi zamagetsi: Zimagwiritsidwa ntchito kwambiri popanga zinthu zochiritsira utomoni wa epoxy. Pambuyo pochiritsidwa ndi hexahydrophthalic anhydride, utomoni wa epoxy umapanga zinthu zomwe zimakhala ndi mphamvu zabwino kwambiri zotetezera kutentha komanso kukhazikika bwino kwa kutentha. Mu ma circuit board osindikizidwa ndi zipangizo zamagetsi zopakira, zimatha kuonetsetsa kuti zida zamagetsi zikugwira ntchito bwino komanso kupewa kulephera kwa magetsi monga ma short circuit ndi kutuluka kwa madzi.
- Mu njira zogwiritsira ntchito zinthu zopangidwa ndi zinthu zosiyanasiyana: Monga zinthu zofunika kwambiri popanga ma resini a polyester osakhuta, zikaphatikizidwa ndi zinthu zolimbitsa monga ulusi wagalasi, zinthu zopangidwa ndi fiberglass zopangidwa ndi zinthu zosiyanasiyana zimakhala zolimba komanso zopepuka. Zimagwiritsidwa ntchito kwambiri popanga zinthu zamlengalenga, zombo, ndi zamagalimoto, monga mapanelo amkati mwa ndege, zophimba zombo, ndi zophimba thupi zamagalimoto. Ngakhale kuti zimakwaniritsa zofunikira za makina, zimakhalanso zopepuka ngati zida zina.
- Mu makampani opanga zomatira: Hexahydrophthalic anhydride imatha kusintha mawonekedwe a zomatira komanso mphamvu ya zomatira. Zimathandiza zomatirazo kukhala ndi zomatira zabwino komanso zomatira zokhazikika. Zimagwiritsidwa ntchito kwambiri pomatira zinthu zosiyanasiyana monga zitsulo, mapulasitiki, ndi matabwa. Mwachitsanzo, njira zomatira zomwe zimagwiritsidwa ntchito popanga mipando ndi kupanga zida zamagetsi sizingathe popanda izi.
Kulongedza ndi Kutumiza
25KG/Drum kapena malinga ndi zomwe makasitomala amafuna.
Kutumiza: Mitundu 8 ya katundu woopsa ndipo imatha kutumizidwa kudzera panyanja.
Sungani ndi kusunga
Nthawi yosungiramo zinthu: Miyezi 24 kuyambira tsiku lopangidwa m'maphukusi oyambirira osatsegulidwa, osungidwa pamalo ozizira komanso ouma, kutali ndi dzuwa, madzi.
Nyumba yosungiramo zinthu zopumira mpweya, Youma pang'ono, Yosiyana ndi ma oxidants, ma acid.
