nkhani

FRP imagwiritsidwa ntchito kwambiri pankhani yolimbana ndi dzimbiri. Ili ndi mbiri yayitali m'maiko otukuka kwambiri. FRP yapakhomo yolimbana ndi dzimbiri yakhala ikukula kwambiri kuyambira m'ma 1950, makamaka m'zaka 20 zapitazi. Kuyambitsidwa kwa zida zopangira ndi ukadaulo wa zinthu zopangira ndi zinthu za FRP zosagwirizana ndi dzimbiri, komanso mitundu ndi ntchito za zinthu za FRP zosagwirizana ndi dzimbiri zikuchulukirachulukira m'magawo osiyanasiyana azachuma cha dziko.

1. Amagwiritsidwa ntchito kwambiri poteteza chilengedwe

Chifukwa cha chitukuko cha mafakitale, vuto la kuipitsidwa kwa chilengedwe lakhala limodzi mwa nkhawa zomwe anthu ambiri padziko lonse lapansi akukumana nazo masiku ano. Mayiko ambiri agwiritsa ntchito mphamvu zambiri ndi zinthu zina kuti adzipereke ku gawo latsopano la mafakitale oteteza chilengedwe.

FRP yakhala ikugwiritsidwa ntchito kwambiri mu uinjiniya wa mapaipi operekera madzi ndi madzi otayira madzi. M'zaka zaposachedwapa, mitundu yambiri ya madzi otayira ndi zinthu zowononga komanso mphamvu ya dzimbiri zikuchulukirachulukira, zomwe zimafuna kugwiritsa ntchito zipangizo zomwe zimalimbana bwino ndi dzimbiri, ndipo pulasitiki yolimba yagalasi yosagonjetsedwa ndi dzimbiri ndiyo yabwino kwambiri yokwaniritsa izi.

Kugwiritsa ntchito zinthu zopangidwa ndi zinthu zosiyanasiyana poteteza chilengedwe kumaphatikizapo kuchiza mpweya woipa wa mafakitale, kuchiza madzi amafuta, kuchiza zinyalala ndi zinthu zoopsa, kuchiza zinyalala, komanso kuchotsa fungo la madzi a m'matauni.

2. Amagwiritsidwa ntchito kwambiri mumakampani azakudyaKukana dzimbiri kwa pulasitiki yolimbikitsidwa ndi ulusi wagalasi kumatanthauza kuti zinthuzi zili ndi mphamvu komanso zogwira mtima.  makhalidwe osadetsa, ndipo mwachibadwa imatha kukhala chinthu choyera kwambiri, monga kusungiramo  madzi oyera kwambiri, mankhwala, vinyo, mkaka ndi zinthu zina zomwe mungasankhe. United States ndi Japan ali ndi  mafakitale apadera a zinthu zamtunduwu, ndipo ali ndi luso lochuluka pozigwiritsa ntchito.  Opanga mafakitale am'nyumba nawonso akhala akutsatira mwachangu m'zaka zaposachedwa, ndipo mwina apeza phindu.  3. Amagwiritsidwa ntchito kwambiri m'mafakitale a chlor-alkaliMakampani opanga chlor-alkali ndi amodzi mwa malo oyamba kugwiritsa ntchito a FRP ngati zinthu zosagwira dzimbiri.  Pakadali pano, FRP yakhala chinthu chachikulu chomwe chimagwiritsidwa ntchito kwambiri mumakampani opanga chlor-alkali. Kale kwambiri kumayambiriro kwa zaka za m'ma 1950, FRP  Poyamba idagwiritsidwa ntchito kusonkhanitsa kutentha (93°C), chlorine wonyowa, ndi zinthu zachilengedwe kuchokera ku ma electrode a inki.  anasintha pulasitiki ya phenolic asbestos panthawiyo. Pambuyo pake, FRP inagwiritsidwa ntchito kusintha chivundikiro cha konkire  selo yamagetsi, yomwe idathetsa vuto la thovu la konkire lozimiririka lomwe lidagwera mu selo yamagetsi.  Kenako, FRP yakhala ikugwiritsidwa ntchito pang'onopang'ono m'machitidwe osiyanasiyana a mapaipi, kuyenda kwa mpweya wophulika, zipolopolo zosinthira kutentha, ndi madzi amchere.  matanki, mapampu, maiwe osambira, pansi, mapanelo a pakhoma, ma grille, zogwirira, zitsulo ndi nyumba zina zomangira. Nthawi yomweyo,  FRP yayambanso kulowa m'magawo osiyanasiyana amakampani opanga mankhwala.

4. Amagwiritsidwa ntchito kwambiri popanga mapepala

Makampani opanga mapepala amagwiritsa ntchito matabwa ngati zipangizo zopangira. Njira yopangira mapepala imafuna ma acid, mchere, zinthu zoyeretsera, ndi zina zotero, zomwe zimakhudza kwambiri zitsulo. Zipangizo zapulasitiki zolimbikitsidwa ndi ulusi wagalasi zokha ndi zomwe zimatha kupirira malo ovuta monga mycotoxins. FRP yagwiritsidwa ntchito popanga zamkati m'maiko ena. Posonyeza kukana kwake dzimbiri.
