Kodi ma FRP (fiberglass reinforced plastic) amakana bwanji kuwala kwa ultraviolet ndi ma acid / alkalis?

FRP (pulasitiki yolimba ya fiberglass)kuwala{{0}mapanelo opatsirana makamaka amayang'anizana ndi cheza cha UV, asidi ndi dzimbiri la alkali, ndi nyengo yapaderadera kudzera m'mapangidwe okonzedwa bwino komanso momwe amapangidwira. Vuto lalikulu lagona pakupeza kulinganiza pakati pa magwiridwe antchito achitetezo, kufalikira kwa kuwala, ndi kulimba.

1. Chitetezo cha UV: Kuteteza Pamwamba + Kulimbana ndi Nyengo ya Substrate - Inshuwaransi Yawiri

Ma radiation a UV amatha kupangitsa matabwa kukhala achikasu, kukhala osasunthika, komanso kutaya kuwala. Chinsinsi chachitetezo chagona pa "surface barrier" ndi "substrate anti-anti ukalamba."

Surface UV-Restant Coating: Chophimba{1}} chapamwamba kwambiri cha UV choteteza (kawirikawiri PMMA) chimatulutsidwa-pabodi, ndikuchindikira pakati pa 50-100μm. Chosanjikizachi chimatha kuwonetsa kapena kuyamwa 90% ya kuwala kwa UV, kuteteza kuwonongeka kwa mkati.

Nyengo-Resin Substrate yosamva: Nyengo-yosamva unsaturated polyester resin imagwiritsidwa ntchito m'malo mwa utomoni wamba, kumathandizira kuti UV usavutike ndi komwe umachokera komanso amachepetsa kuwonongeka ndi kusweka pakatha-panthawi yayitali.

Mawonekedwe Osasinthika: Makulidwe okutira amafunikira kuwongolera bwino. Wowonda kwambiri wosanjikiza amapereka chitetezo chosakwanira, pomwe wokhuthala kwambiri amachepetsa kufalikira kwa kuwala. Kukula kwa 50-100μm kumakwaniritsa zofunikira zonse zachitetezo komanso kufalitsa kuwala.

2. Kulimbana ndi Acid ndi Alkali Corrosion: Resin Selection + Structural Isolation

Malo a acidic ndi amchere amatha kuwononga pamwamba pa bolodi ndikulowa mkati mwake, zomwe zimatsogolera ku delamination. Chinsinsi chake ndi chitetezo chapawiri kudzera mu "kukana kutukuta kwa zinthu" ndi "kudzipatula mwakuthupi."

Kufananiza ndi Resin Monga Kukufunikira: Sankhani mtundu wa resin malinga ndi kuchuluka kwa dzimbiri. Pa dzimbiri pang'ono (mwachitsanzo, m'mafakitale a zakudya), gwiritsani ntchito phthalic resin; pa dzimbiri zolimbitsa thupi (mwachitsanzo, mu electroplating workshops ndi zomera mankhwala), ntchito isophthalic kapena vinilu ester utomoni. Zotsirizirazi zimatha kusintha kukana kwa asidi ndi zamchere ndi nthawi 3-5.

Dense Fiberglass Layer Protection: Mkati mwake mumagwiritsa ntchito nsalu za alkali-zaulere za fiberglass, zomwe zimalimbana ndi mankhwala ndipo zimakhala zotchinga zotchinga, zomwe zimalepheretsa asidi ndi alkali kuti asalowe mkatikati mwa utomoni ndikupewa matuza ndi kuphulika.

Chithandizo cha Smooth Surface: Pamwamba pa bolodi amapukutidwa kuti achepetse porosity ndi kusafanana, kuchepetsa malo omatira a acid ndi alkali solution, komanso kumathandizira kuyeretsa ndi kuchepetsa zotsalira zowononga.
