Mu dziko lomanga lomwe likusintha nthawi zonse, zipangizo zomwe timasankha zimatha kukhudza kwambiri magwiridwe antchito ndi malo omwe mapulojekiti athu amagwirira ntchito. M'zaka zaposachedwapa, chinthu chatsopano chomwe chakopa chidwi chachikulu ndi polypropylene plastic formwork (PP formwork). Blog iyi ifufuza zabwino zambiri zogwiritsa ntchito PP formwork, kuyang'ana kwambiri kukhazikika kwake, kulimba kwake komanso magwiridwe antchito ake onse poyerekeza ndi zipangizo zachikhalidwe monga plywood ndi chitsulo.
Chitukuko chokhazikika ndichofunikira kwambiri
Chimodzi mwa zabwino kwambiri zapulasitiki ya polypropylenendi kukhazikika kwake. Mosiyana ndi zipangizo zachikhalidwe zopangira mafomu, PP formwork idapangidwa kuti igwiritsidwenso ntchito ndipo imatha kugwiritsidwanso ntchito nthawi zoposa 60, ndipo nthawi zina nthawi zoposa 100, makamaka m'misika monga China. Kugwiritsanso ntchito bwino kumeneku sikungochepetsa zinyalala komanso kumachepetsa kufunikira kwa zipangizo zatsopano, zomwe zimapangitsa kuti ikhale chisankho chosawononga chilengedwe pa ntchito zomanga. Pamene makampani omanga akugogomezera kwambiri njira zokhazikika, kugwiritsa ntchito PP formwork kukugwirizana bwino ndi zolinga izi.
Kuchita bwino kwambiri komanso kulimba
Ponena za magwiridwe antchito, pulasitiki ya polypropylene imagwira ntchito bwino kuposa plywood ndi chitsulo. PP formwork ili ndi kulimba komanso mphamvu zonyamula katundu kuposa plywood, zomwe zimapangitsa kuti ikhale chisankho chodalirika pa ntchito zosiyanasiyana zomanga. Kapangidwe kake kolimba kamatsimikizira kuti imatha kupirira zovuta zomanga popanda kuwononga umphumphu wa kapangidwe kake. Kulimba kumeneku kumatanthauza kuti sikukonzanso ndi kusintha zinthu zambiri, zomwe pamapeto pake zimapulumutsa nthawi ndi ndalama kwa omanga.
Kuphatikiza apo, PP formwork imalimbana ndi chinyezi, mankhwala ndi kusinthasintha kwa kutentha komwe nthawi zambiri kumawononga zipangizo zachikhalidwe. Kulimba mtima kumeneku kumatanthauza kuti mapulojekiti amatha kuyenda bwino popanda kuchedwa komwe kumachitika chifukwa cha kulephera kwa formwork, kuonetsetsa kuti mapulojekiti amalizidwa pa nthawi yake komanso pa bajeti.
Kugwiritsa Ntchito Mtengo Moyenera ndi Kuchita Bwino
Kuwonjezera pa kulimba, mapepala apulasitiki a polypropylene amapereka ubwino waukulu pamtengo. Ngakhale kuti ndalama zoyamba zitha kukhala zokwera kuposa plywood, ndalama zomwe zingasungidwe kwa nthawi yayitali sizingatsutsidwe. Chifukwa cha kuthekera kogwiritsanso ntchito.Fomu ya PPNthawi zambiri, makampani omanga amatha kuchepetsa kwambiri ndalama zogulira zinthu pa moyo wonse wa polojekiti. Kuphatikiza apo, PP formwork ndi yopepuka komanso yosavuta kuyigwiritsa ntchito komanso kunyamula, zomwe zimapangitsa kuti ntchito ikhale yosavuta. Kugwiritsa ntchito mosavuta kumeneku kungafupikitse nthawi yomaliza ntchito, zomwe zimapangitsa kuti kugwiritsa ntchito matemplate a PP kukhale kopindulitsa kwambiri.
Mphamvu yapadziko lonse lapansi komanso zomwe zachitika bwino
Kuyambira pomwe tidakhazikitsidwa mu 2019, takhala tikudzipereka kukulitsa gawo lathu pamsika ndikupereka matempulo apamwamba apulasitiki a polypropylene kwa makasitomala m'maiko pafupifupi 50 padziko lonse lapansi. Chidziwitso chathu pakukhazikitsa njira zogulira zinthu zonse chimatithandiza kukonza magwiridwe antchito ndikuwonetsetsa kuti makasitomala athu alandira zinthu ndi ntchito zabwino kwambiri. Pamene tikupitiliza kukula, tikupitilizabe kudzipereka pakulimbikitsa njira zomangira zokhazikika ndikuthandiza makasitomala athu kukwaniritsa zolinga zawo za polojekiti.
Pomaliza
Mwachidule, ubwino wa ma tempuleti a pulasitiki a polypropylene ndi woonekeratu. Kukhalitsa kwake, magwiridwe antchito apamwamba, kugwiritsa ntchito bwino ndalama komanso kufikira padziko lonse lapansi zimapangitsa kuti ikhale yoyenera ntchito zomanga zamakono. Pamene makampani akupita patsogolo ku njira zosamalira chilengedwe, mawonekedwe a PP amawonekera, osati kungokwaniritsa zosowa za zovuta zomanga zamasiku ano komanso kuthandizira tsogolo lokhazikika. Kugwiritsa ntchito zinthu zatsopanozi kungabweretse phindu lalikulu kwa makontrakitala, makasitomala ndi dziko lapansi.
