nkhani

Frp imagwiritsidwa ntchito kwambiri m'munda wa kuponderezedwa. Ili ndi mbiri yayitali m'maiko otukuka. Frp yapanyumba yomwe idagonjetsedwa kale idatukuka kwambiri kuyambira 1950s, makamaka zaka 20 zapitazi. Kukhazikitsidwa kwa zida ndi ukadaulo wa zopangira zachilengedwe zophatikizika ndi zinthu zina, ndi mitundu ndi ntchito zazinthu zokhudzana ndi FRP zikuyamba kukula ndi zinthu zosiyanasiyana zapadziko lonse.

1. Kugwiritsidwa ntchito kwambiri poteteza zachilengedwe

Ndi chitukuko cha mafakitale, vuto la kuwonongeka kwa chilengedwe kwakhala nkhawa wamba za anthu padziko lapansi masiku ano. Mayiko ambiri apereka mphamvu zolimbitsa thupi ndi zinthu zakuthupi kuti adzipereke ku malonda oteteza zachilengedwe.

Frp yagwiritsidwa ntchito kwambiri m'madzi ndi maimini a Piipiner. M'zaka zaposachedwa, mitundu yambiri yamadzi ndi mitundu yonyansa ndi mphamvu zowononga nthawi zonse zikuwonjezeka, zomwe zimafuna kugwiritsa ntchito zida zotetezedwa, komanso pulasitiki yolimba kwambiri kuti ikwaniritse izi.

Kugwiritsa ntchito zida zopangira zachilengedwe kumaphatikizapo chithandizo chambiri mafakitale, mankhwala osokoneza mafuta, chithandizo cha ing'onoge ndi matenda oopsa, mankhwala opatsirana am'matambo.

2. Kugwiritsa ntchito kwambiri makampani ogulitsa zakudyaKukana Kwambiri Kukula kwapulifi wagalasitiki kumatanthauza kuti izi zili ndi moyo komanso  machitidwe osadetsa, ndipo chilengedwe chimatha kukhala choyera kwambiri, monga kusungidwa kwa  Madzi ambiri oyera, mankhwala, vinyo, mkaka ndi zinthu zina zosankha. United States ndi Japan ali  Mafakitale apadera a zinthu zamtunduwu, ndipo apeza ndalama zambiri pakugwiritsa ntchito.  Opanga nyumba atsatirapo mwachangu m'zaka zaposachedwa, ndipo atha kugwira.  3. Wogwiritsidwa ntchito kwambiri m'munda wa chlor-alkaliMakampani opanga chlor-alkali ndi amodzi mwa magawo oyamba kwambiri a frp ngati zinthu zosagonjetseka.  Pakadali pano, Frp yasanduka nkhani yayikulu ya chlor-alkali. Kuyambira koyambirira kwa zaka za m'ma 1950, Frp  Choyambirira chimagwiritsidwa ntchito kutolera kutentha (93 ° C), chlorine wonyowa, komanso zinthu zachilengedwe kuchokera ku inki electrodes. Ntchito iyi  Sinthani pulasitiki ya phenolil asbestos panthawiyo. Pambuyo pake, Frp idagwiritsidwa ntchito m'malo mwa konkriti  Selo la ma electrolytic, lomwe limathetsa vuto la chithovu cha konkriti cholumikizira chija chikugwa mu khungu la electrolytic. Kuyambira  Kenako, Frp yakhala ikugwiritsidwa ntchito pang'onopang'ono m'magulu osiyanasiyana, mpweya wosuntha, kutentha zipolopolo, brine  Matanki, mapampu, mapesi, pansi, mapandelo a khoma, grilles, mapepala, njati ndi nyumba zina zomanga. Nthawi yomweyo,  Frp yayambanso kulowa m'minda yosiyanasiyana yamakampani.

4. Kugwiritsidwa ntchito kwambiri m'munda wamapepala

Makampani apepala amagwiritsa ntchito mitengo ngati zopangira. Njira yopanga pepala imafunikira macidis, mchere, ogulitsira magazi, ndi zina zambiri, zomwe zimakhala ndi mphamvu yopweteka pa zitsulo. Zida za pulasitiki zokhazokha zimatha kupirira malo okhala zikwangwani monga mycotoxins. Frp yakhala ikugwiritsidwa ntchito popanga zamkati m'maiko ena. Posonyeza kukana kwake kwabwino kwambiri.
