Nqi: 120-200 ib square meter (ib zaug yuav), 0.4-0.8 ib square meter ib siv.
4. Plastic Formwork: Eco- Tus phooj ywg & Smooth rau kev ua tiav tshwj xeeb
Yas formwork, ua los ntawm high- ntom polyethylene (HDPE) los yog polypropylene (PP), yog ib qho kev xaiv ruaj khov tsim nyog rau tej yaam num uas yuav tsum tau siab - pob zeb zoo.
Cov yam ntxwv tseem ceeb:
Khoom siv: Txhawb nqa HDPE / PP panels, feem ntau nrog cov hlau ntxig rau lub zog.
Qhov zoo: Lub teeb yuag (10-15kg rau ib lub vaj huam sib luag), tsis yog- nplaum nto (yooj yim demolding), corrosion-resistant, thiab reusable (50-100 cycles).
Kev txwv: Tsawg load-cov kabmob muaj peev xwm (txog 30kN / ㎡), tsis tshua muaj zog dua steel / aluminium, thiab tsis tsim nyog rau qib siab -qib qhob pouring.
Qhov zoo tshaj plaws Scenarios: Cov phab ntsa hauv tsev, kab, thiab tej yaam num uas yuav tsum tau ua kom tiav cov pob zeb ua tiav yam tsis muaj plastering.
Nqi: 50-80 ib square meter (ib zaug yuav), 0.8-1.5 ib square meter ib siv.
5. Lub teeb yuag hlau Formwork: Qhov zoo tshaj plaws ntawm ob lub ntiaj teb rau cov haujlwm nyuaj
Raws li ib qho kev hloov kho tshiab rau cov tsoos steel formwork, lub teeb yuag steel formwork sib txuas cov kav ntev ntawm cov hlau nrog kev txav ntawm txhuas. Ua los ntawm siab - lub zog alloy steel (1.8-} 2.2mm tuab), nws hais txog qhov mob ntawm cov hlau hnyav hnyav thiab cov nqi siab aluminium.
Cov yam ntxwv tseem ceeb:
* Khoom siv: High-lub zog alloy steel (Mn-Cr muaj pes tsawg leeg) nrog nano- hnav- tiv thaiv txheej.
* Qhov zoo: Ultra-hnyav (22-25kg ib lub vaj huam sib luag, manually thauj), siab load-bearing peev (45-50kN / ㎡), siab reuse tus nqi (150-180 cycles), thiab ceev sib dhos (6-8㎡ ib tug neeg ua hauj lwm ib teev).
* Cov kev txwv: Tus nqi pib dua me ntsis dua li cov qauv hlau ib txwm muaj (offset los ntawm kev txuag nyiaj ua haujlwm).
* Cov xwm txheej zoo tshaj plaws: High-cov tsev nce siab, qhov chaw nqaim (piv txwv li, of elevator shafts, subway tunnels), thiab tej yaam num uas yuav tsum tau muaj kev txav mus los thiab ua haujlwm ntev.
* Nqi: 90-160 ib square meter (ib zaug yuav), 0.3-0.6 ib square meter ib siv.

Yuav Ua Li Cas Xaiv Txoj Cai Formwork? 4 Cov ntsiab lus tseem ceeb
1. Qhov project Scale & Hom: Cov haujlwm me me nrog cov duab kev cai haum rau ntoo / yas formwork; loj- nplai lossis siab- cov phiaj xwm nce siab tau txais txiaj ntsig los ntawm steel / aluminium / lub teeb hnyav hlau.
2. Kev tsim kho lub voj voog: Fast-cov haujlwm hloov pauv yuav tsum tau ceev- cov tshuab sib dhos (txhuas, lub teeb yuag steel) kom txo qis sijhawm.
3. Ntev-Tus Nqi Sij Hawm: xam tag nrho cov nqi (thawj + tu + hloov) es tsis yog kev nqis peev ua ntej xwb - steel / lightweight steel muab tus nqi qis tshaj rau - siv.
4. Qhov chaw nyob: Qhov chaw nqaim lossis tej yaam num uas tsis muaj cov cuab yeej siv hnyav yuav tsum muaj kev xaiv lub teeb (txhuas, lub teeb yuag steel).
Kev xav zaum kawg: Kev nqis peev hauv tus nqi, tsis yog tus nqi xwb
Txawm hais tias ntoo formwork tej zaum yuav zoo li pob nyiaj siv- thawj tus phooj ywg, nws tus nqi rov qab siv tsawg ua rau cov nqi ntev dua - rau cov haujlwm loj. Rau cov neeg cog lus txhawm rau sib npaug kev ua haujlwm, ua haujlwm ntev, thiab muaj txiaj ntsig, steel formwork (rau hnyav-cov haujlwm xav tau) thiab lub teeb hnyav steel formwork (rau portability + lub zog) yog qhov kev xaiv zoo tshaj plaws.
Ntawm Shaanxi Flourish Industrial Co., ltd., peb tshwj xeeb hauv siab -cov hlau zoo thiab lub teeb yuag steel formwork tshuab- suav nrog Reusable Steel Formwork (300+ cycles) thiab Lub Teeb Meem Hlau Formwork (manually transportable, 45kN / ㎡ load-} niaj hnub xav tau){{ kev tsim kho. Cia peb tsim kom muaj txiaj ntsig zoo, nyab xeeb, thiab raug nqi- ua tau zoo- ua ke.
