FRP imagwiritsidwa ntchito kwambiri polimbana ndi dzimbiri.Ili ndi mbiri yakale m'mayiko otukuka kwambiri.FRP yolimbana ndi dzimbiri m'nyumba yapangidwa kwambiri kuyambira m'ma 1950, makamaka zaka 20 zapitazi.Kukhazikitsidwa kwa zida zopangira ndi ukadaulo wa zida ndi zinthu za FRP zolimbana ndi dzimbiri, komanso mitundu ndikugwiritsa ntchito kwa zinthu za FRP zolimbana ndi dzimbiri zikuchulukirachulukira m'magawo osiyanasiyana azachuma chadziko.

1. Amagwiritsidwa ntchito kwambiri poteteza chilengedwe

Ndi chitukuko cha mafakitale, vuto la kuwonongeka kwa chilengedwe lakhala limodzi mwazinthu zomwe anthu ambiri amadetsa nkhawa masiku ano padziko lapansi.Maiko ambiri ayika ndalama zambiri zogwirira ntchito ndi chuma kuti adzipereke ku gawo latsopano la mafakitale lachitetezo cha chilengedwe.

FRP yakhala ikugwiritsidwa ntchito kwambiri popereka madzi ndi uinjiniya wa mapaipi otulutsa ngalande.M'zaka zaposachedwa, madzi akuwonongeka ochulukirachulukira komanso mitundu yazakudya zowononga komanso mphamvu zowononga zikuchulukirachulukira, zomwe zimafunikira kugwiritsa ntchito zida zolimbana ndi dzimbiri, ndipo pulasitiki yosagwira magalasi osagwira magalasi ndi zinthu zabwino kwambiri kuti zikwaniritse izi.

Kugwiritsa ntchito zinthu zophatikizika poteteza chilengedwe kumaphatikizapo kuthira gasi wotayidwa m'mafakitale, kuthira mafuta m'madzi, kuthira zinyalala ndi zinthu zapoizoni, kutenthetsa zinyalala, komanso kuthira madzi onyansa m'matauni.

2. Zogwiritsidwa ntchito kwambiri m'makampani azakudyaKukana kwa dzimbiri kwa magalasi olimba a pulasitiki kumatanthauza kuti nkhaniyi ili ndi moyo komanso  makhalidwe osaipitsa, ndipo akhoza mwachibadwa kukhala chinthu choyera kwambiri, monga kusungirako  madzi oyeretsedwa kwambiri, mankhwala, vinyo, mkaka ndi zipangizo zina zomwe mungasankhe.United States ndi Japan zatero  mafakitale apadera opangira zinthu zamtunduwu, ndipo apeza luso logwiritsa ntchito bwino.  Opanga zapakhomo nawonso akhala akutsata mwachangu m'zaka zaposachedwa, ndipo akuyenera kuti akwaniritse.  3. Amagwiritsidwa ntchito kwambiri pamakampani a chlor-alkaliMakampani a chlor-alkali ndi amodzi mwamagawo oyamba kugwiritsa ntchito FRP ngati zinthu zolimbana ndi dzimbiri.  Pakadali pano, FRP yakhala chinthu chachikulu pamakampani a chlor-alkali.Kumayambiriro kwa zaka za m'ma 1950, FRP  Anayamba kugwiritsidwa ntchito kusonkhanitsa kutentha (93 ° C), klorini yonyowa, ndi zinthu zamoyo kuchokera ku maelekitirodi a inki.Izi ntchito  m'malo mwa phenolic asbestos pulasitiki panthawiyo.Pambuyo pake, FRP idagwiritsidwa ntchito kusintha chivundikiro cha konkire  electrolytic cell, yomwe idathetsa vuto la thovu la konkriti lowonongeka lomwe limagwera mu cell electrolytic.Kuyambira  ndiye, FRP wakhala ntchito pang'onopang'ono mu machitidwe osiyanasiyana mapaipi, mpweya kuphulika kuyenda, kutentha exchanger zipolopolo, brine.  akasinja, mapampu, maiwe, pansi, mapanelo khoma, grilles, zogwirira, njanji ndi zomangira zina.Nthawi yomweyo,  FRP yayambanso kulowa m'magawo osiyanasiyana amakampani opanga mankhwala.

4. Amagwiritsidwa ntchito kwambiri pakupanga mapepala

Makampani opanga mapepala amagwiritsa ntchito nkhuni ngati zopangira.Kupanga mapepala kumafuna asidi, mchere, bleaching agents, etc., zomwe zimakhala ndi mphamvu zowonongeka pazitsulo.Ndi zinthu zapulasitiki zolimba zagalasi zokha zomwe zimatha kupirira malo ovuta monga mycotoxins.FRP yakhala ikugwiritsidwa ntchito popanga zamkati m'maiko ena.Posonyeza kukana kwake kwa dzimbiri.
