Steelcraft hollow hlau cov qhov rooj yog ua los ntawm ntau yam ntawm cov cheebtsam. Ib qho ntawm cov feem tseem ceeb tshaj plaws yog cov khoom siv tseem ceeb. Ntawm no yog 5 ntawm cov qauv txheem cov hom siv hauv cov hlau wollow hlau:
1.HoneyComb
2.Polystyrene
3.Polyurethane
4.steel stiffened
5.Muaj kev loj
1. Honeycomb
Honeycomb cores tau txais lawv lub npe los ntawm honeycomb zoo li daim duab los qhia uas yog tawv tawv los ntawm cov resins tshwj xeeb. Cov ntaub ntawv no yog feem ntau siv nyob rau sab hauv qhib thiab yog lub luag haujlwm hnyav, ruaj khov. Nws tuaj yeem yog hluav taws kub ntsuas li 3 teev. Cov nqi rwb thaiv tsev yog qis dua li cov tub ntxhais ua npuas ncauj tab sis nws tuaj yeem siv tau ntawm kev qhib sab nrauv yog tias muaj kev daws teeb meem zoo yog qhov xav tau.
2. Polystyrene
Thawj theem ntawm insulated qhov rooj core yog cov polystyrene uas yog ib qho uas ua npuas ncauj uas tau muab tso rau hauv qhov chaw ntawm lub qhov rooj. Hollow hlau cov rooj nrog cov hom tseem ceeb no feem ntau siv ntawm kev qhib sab nrauv thiab tuaj yeem yog hluav taws kub rau 3 teev. Cov nqi rwb thaiv tsev yog qhov siab dua cov honeycomb tab sis qis dua cov polyurethane.
3. Polyurethane
Cov tub ntxhais insulated no yog ua npuas ncauj uas tau txhaj rau hauv cov tub ntxhais thiab nthuav dav los sau tag nrho cov chaw nyob hauv kab noj hniav hauv lub hollow hlau qhov rooj. Polyurethane yuav muaj qhov zoo tshaj plaws rwb thaiv rwb thaiv rwb thaiv rwb thaiv cov txiaj ntsig uas yog siab dua ob lub honeycomb thiab polystyrene. Txawm li cas los xij, lub qhov rooj polyurethanetsis taumuab hluav taws rau hluav taws.
4. Hlau txhav
Hlau stiffened hollow hlau qhov rooj muaj steel channel uas khiav tag nrho qhov siab ntawm lub qhov rooj thiab tau nrug txog 6 "oc hla qhov rooj. Lawv yog cov chaw welded rau cov ntsej muag thiab cov khoob ntawm cov channel tau muaj nrog rwb thaiv tsev. Cov qhov rooj no feem ntau tau teev nyob rau ntawm thaj chaw ua phem lossis siv tau ntawm kev qhib uas cov suab sib ntaus sib npaug yog qhov kev txhawj xeeb.
5. Cov Tub Ntxhais Ntxaij
Hollow hlau lub qhov rooj tuaj yeem sau nrog qhov ntsuas kub uas yuav xav tau daim ntawv ntawm cov ntxhia pob zeb tso rau hauv lub qhov rooj. Cov khoom siv no muaj cov khoom uas txo cov cua sov uas hloov los ntawm lub qhov rooj mus rau sab nraud ntawm qhov qhib. Rauv ntsuas kub tau tuaj yeem yog 250, 450 lossis 650 degrees uas qhov qis dua kev ntaus nqi ntawm 250 ua tau zoo dua li cov kev ntsuas siab dua. Thaum muaj hluav taws, qhov no tso cai rau cov neeg ua haujlwm kom dhau los ntawm kev qhib tsis raug cai los ntawm cov cua kub los ntawm hluav taws.
