Gulu la fiberglass reinforced pulasitiki (FRP) air dampers yamalizidwa kupanga. Masiku angapo apitawo, zochepetsera mpweya izi zidadutsa pakuwunika mosamalitsa mumsonkhano wa Jinbin. Iwo anali makonda malinga ndi zofuna za makasitomala, opangidwa ndi galasi CHIKWANGWANI analimbitsa pulasitiki, ndi miyeso ya DN1300, DN1400, DN1700, ndi DN1800. Zonse zili ndi zida zapamwamba kwambiri zamagetsi komanso zamanja. Pakali pano, ogwira ntchito m'mashopu anyamula gulugufelivalavu zakudandipo akuyembekezera kuwatumiza ku Indonesia.

Ubwino waukulu wa ma valve a mpweya wa FRP wagona pakulemera kwawo komanso mphamvu yayikulu. Poyerekeza ndi zida zachitsulo zachikhalidwe, kachulukidwe kake ndi pafupifupi kotala la chitsulo, komabe imatha kukhalabe ndi mphamvu zambiri, kuchepetsa kwambiri ndalama zogwirira ntchito ndi zakuthupi panthawi yoyendetsa ndi kukhazikitsa. Pakadali pano, FRP ili ndi kukana bwino kwa dzimbiri.

Kaya m'madera a m'mphepete mwa nyanja yachinyontho ndi mvula kapena m'malo opangira mankhwala okhala ndi asidi wambiri ndi mpweya wa alkali, imatha kukana kukokoloka, kukulitsa moyo wake wautumiki, ndikuchepetsa kuchuluka kwa kukonzanso ndikusintha pambuyo pake. Kuphatikiza apo, nkhaniyi ilinso ndi kutentha kwabwino kwambiri komanso kutulutsa mawu. Panthawi ya mpweya wabwino, sizingateteze kutentha kwa kutentha komanso kuchepetsa mphamvu ya phokoso pa chilengedwe, kupanga malo abata komanso omasuka.

M'makampani opanga mankhwala, ma valve a mpweya a FRP atha kugwiritsidwa ntchito kutulutsa mpweya wowononga. Pamsonkhano wokonza chakudya, chifukwa cha mawonekedwe ake osakhala ndi poizoni komanso opanda zowononga, amakwaniritsa miyezo yaukhondo wazakudya ndipo amatha kutsimikizira chitetezo cha chilengedwe. M'makina olowera mpweya wa malo oimikapo magalimoto apansi panthaka, ma subways, ndi zina zambiri, kulemera kwake komanso mphamvu zake zambiri kumapangitsa kuti ikhale yosavuta kuyiyika, ndipo kukana kwake kwa dzimbiri kumapangitsa kuti ikhale yoyenera malo achinyezi.

Mavavu a Jinbin amagwira ntchito popanga mavavu azitsulo, ma damper osiyanasiyana akulu-m'mimba mwake, mavavu a pachipata, ma valve agulugufe, ma cheke, zipata za penstock, etc. Titha kusintha malinga ndi zosowa zosiyanasiyana. Kwa mavavu aku mafakitale ndi ma valve opangira madzi, sankhani ma Vavu a Jinbin!
