Indlela yokubala ubunzima bephepha leAluminiyam: 4×8, 1/8″, 3mm & Kaninzi (NgeFormula)
Ukuba ufumana amaphepha e-aluminiyam ukuze enze, ukwakhiwa, okanye ukuvelisa, ukwazi ukubala ubunzima bephepha kubalulekile. Ubunzima bumisela iindleko zokuthumela, imida yomthwalo wesakhiwo, iimfuno zokuphatha izinto, kwaye - ngokubalulekileyo - ixabiso leyunithi nganye xa uthenga ngetoni.
Nangona kunjalo abathengi abaninzi baxhomekeke kwimigaqo yobhontsi okanye uqikelelo lomthengisi olunokususwa nge-5-10%. Esi sikhokelo sikunika ifomyula echanekileyo, itafile yereferensi ekhawulezayo yeesayizi eziqhelekileyo, kunye ne-alloy-specific densific values oyifunayo ukubala ubunzima ngokuzithemba.
Ifomula yobunzima obusisiseko
Ukubala ubunzima bephepha le-aluminiyam kuqondile xa unefomula efanelekileyo. Ubunzima balo naliphi na iphepha lesinyithi esicaba:
Ubunzima (ikg) = Ubude (m) × Ububanzi (m) × Ukutyeba (mm) × Ubuninzi (g/cm³)
Kutheni oku kusebenza: Xa uphinda-phinda ubude × ububanzi × ubukhulu, ufumana umthamo kwi-cubic metres (m³). Ukuphinda-phinda ngoxinaniso kwi-g/cm³ kuguqula umthamo ube ziikhilogram kuba 1 g / cm³ = 1000 kg/m³, kwaye uguqulo lwe-mm-to-m lobungqingqwa sele lubaliwe kwisakhiwo sefomula.
Kungenjalo, ukuba ukhetha ukusebenza ngee-intshi kunye neepounds:
Ubunzima (i-Ib) = Ubude (ngaphakathi) × Ububanzi (ngaphakathi) × Ukutyeba (ngaphakathi) × 0.098 (lb/in³ yealuminiyam)
Uxinzelelo lweAluminiyam ngeAlloy
Ayizizo zonke i-aluminiyam ezinoxinano olufanayo. Izinto ezidibanisayo zitshintsha ukuxinana kancinci, kunye nezibalo ezichanekileyo - ngakumbi xa ubeka ixabiso leodolo ephezulu yevolumu - kufuneka usebenzise ixabiso elithile le-alloy:
| Ingxubevange | Ukuxinana (g/cm³) | Ukusetyenziswa okuqhelekileyo |
| 1050 / 1060 / 1100 (icocekile) | 2.70 - 2.71 | Iphepha ngokubanzi, I-Cookiwation, Izixhobo zekhemikhali |
| 3003 / 3004 | 2.72 - 2.73 | Uphahla, amathumbi, izitya zokutya |
| 5005 | 2.69 | Iphepha eline-anodized, bokwakha |
| 5052 | 2.68 | Owaselwandle, imibutho yelori, ukwenziwa jikelele |
| 5083 / 5086 | 2.66 | Owakhiwe ngenqanawa, izakhiwo zaselwandle |
| 5754 | 2.67 | Iimoto, umgangatho, Iinqanawa zoxinzelelo |
| 6061 / 6063 | 2.70 | Ulwakhiwo, umatshini, i-extrusion |
| 7075 | 2.81 | I-Aerospace, izicelo eziphezulu zamandla |
Umthetho okhawulezayo: Kwiishiti ezininzi ze-aluminiyam yorhwebo (1000, 3000, 5000, 6000 uthotho), ungasebenzisa ngokukhuselekileyo 2.70 g/cm³ njengesiseko. Umahluko udla ngokuba ngaphantsi 1.5%, ephakathi kokunyamezela ukwenziwa kwesiqhelo.
Ubungakanani bePhepha eliqhelekileyo kunye nobunzima babo
Iphepha leenyawo le-4 × 8 (1219 mm × 2438 mm) ngumgangatho weshishini kuMntla Melika kunye neemarike ezininzi ezithumela ngaphandle. Ngezantsi itafile yobunzima obubhekiselele ngokukhawuleza kubuninzi obuqhelekileyo, kubalwe kusetyenziswa 2.70 g/cm³:
| Ukutyeba | mm | Ubunzima nge-4 × 8 sheet (ikg) | Ubunzima nge-4 × 8 sheet (i-Ib) | Amaxwebhu ngetoni yemetriki nganye |
| 0.020″ (0.5 mm) | 0.50 | 4.02 | 8.86 | 249 |
| 0.032″ (0.8 mm) | 0.81 | 6.51 | 14.35 | 154 |
| 0.040″ (1.0 mm) | 1.02 | 8.20 | 18.08 | 122 |
| 0.063″ (1.6 mm) | 1.60 | 12.86 | 28.35 | 78 |
| 1/16″ (1.59 mm) | 1.59 | 12.78 | 28.18 | 78 |
| 0.090″ (2.3 mm) | 2.29 | 18.41 | 40.59 | 54 |
| 1/8″ (3.18 mm) | 3.18 | 25.55 | 56.33 | 39 |
| 3/16″ (4.76 mm) | 4.76 | 38.26 | 84.35 | 26 |
| 1/4″ (6.35 mm) | 6.35 | 51.05 | 112.55 | 20 |
| 3/8″ (9.53 mm) | 9.53 | 76.66 | 169.01 | 13 |
| 1/2″ (12.7 mm) | 12.70 | 102.17 | 225.25 | 10 |
Ubalo olusekwe kwi 1219 × 2438 mm ubukhulu bephepha kunye 2.70 g/cm³ ukuxinana. Obona bunzima bunokwahluka ±2% ngenxa yonyamezelo lwemveliso kunye nomahluko wealloyi.
Umzekelo wokubala weNyathelo ngenyathelo
Makhe sihambe ngomzekelo wehlabathi lokwenyani. Masithi kufuneka ubale ubunzima bephepha le-aluminium 5052-H32, 4× 8 iinyawo, 1/8 intshi ubukhulu:
- Guqula imilinganiselo ibe yimetric: Ubude: 8 ft = 2438 mm = 2.438 m; Ububanzi: 4 ft = 1219 mm = 1.219 m; Ukutyeba: 1/8 kwi = 3.175 mm
- Fumana ukuxinana: 5052 ingxubevange = 2.68 g/cm³
- Sebenzisa ifomula: Ubunzima = 2.438 × 1.219 × 3.175 × 2.68 = 25.29 ikg
- Qwalasela ngetafile: Itheyibhile ibonisa 25.55 kg kwi 2.70 g/cm³. Ukusebenzisa ubuninzi be-5052 ye 2.68 inika 25.29 kg - umahluko malunga 1%, yile nto kanye besiyilindele.
Ubunzima vs. Iindleko: Kutheni le nto ibalulekile ekufuneni izinto
Amaphepha e-aluminiyam ahlala exabisa ubunzima (USD/kg okanye USD/toni). Xa ufumana ikowuti, kufuneka uqinisekise ukuba ubunzima obucatshulweyo buhambelana nobunzima bezinto ozithengayo. Nasi isizathu:
- Ubunzima obugqithisileyo = intlawulo engaphezulu. Abanye ababoneleli bacaphula ubunzima obuthiyori obuquka ukunyamezelana okulungileyo (I-E.G., +5%). Ukuba uyahlawula 1000 kg kodwa yamkela 950 ikg, uhlawule ngaphezulu 5%.
- Ukubalwa kweendleko zokuthumela. Umthwalo uhlawuliswa ubunzima bokwenene okanye ubunzima bomthamo, nokuba yeyiphi na ephezulu. Ukwazi ubungakanani bephepha obuchanekileyo kukunceda ukuba uqikelele iindleko ezipheleleyo ozifumeneyo.
- Uyilo lwesakhiwo. Ukuba uyila isakhiwo (uphahla, umzimba trailer, iqonga), umthwalo ofileyo wamaphepha e-aluminium uchaphazela izibalo zakho zobunjineli.
- Ulawulo lwempahla. Ukwazi ukuba mangaphi amashiti angena kwisikhongozeli (20ft okanye 40ft) ikunceda ucwangcise iiodolo kwaye uphephe ngaphantsi- okanye ukuhambisa ngaphezulu.
Mangaphi Amaphepha Angena Kwisikhongozeli?
Ukusebenzisa idatha yobunzima ngasentla, ungaqikelela ukulayisha isikhongozeli:
- 20ft isikhongozeli: ~25,000 kg umthamo womthwalo womvuzo → malunga 980 amaphepha 1/8″ (25.5 kg nganye), okanye ~490 amaphepha 1/4″ (51 kg nganye)
- 40ft isikhongozeli: ~ 28,000 kg umthwalo → malunga 1,100 amaphepha 1/8″, okanye ~550 amaphepha 1/4″
Phawula: Imiqobo yeVolumetric inokunciphisa ukulayisha kumaphepha amancinci. Soloko uqinisekisa ngomthumeli wakho wempahla.
Iimpazamo Eziqhelekileyo Emaziphephe
- Ukusebenzisa ubuninzi obungalunganga. Ukusebenzisa 2.70 kuba 7075 (2.81) ithoba ubunzima nge 4%. Kwii-alloys eziphezulu zamandla, soloko usebenzisa ingxinano echanekileyo.
- Igeyiji ebhidayo ngee-intshi. “16 igeji” ialuminiyam yi0.051″ (1.29 mm), hayi ngo-1/16″ (0.0625″). Imigangatho yokulinganisa iyahluka phakathi kwe-aluminium kunye nentsimbi - ungaze ucinge ukuba ziyafana.
- Ukungahoyi ukunyamezelana. Ubukhulu bephepha bunonyamezelo kwimveliso (ngokwesiqhelo ±0.05 mm okanye ±5%). A “3 mm” Iphepha linokuba yi-2.85–3.15 mm, echaphazela ubunzima ngokufikelela 5%.
- Ukulibala ifilimu ekhuselayo. Amanye amaphepha eza kunye nefilimu ekhuselayo yePVC, eyongeza umlinganiselo omncinci wobunzima (ngokuqhelekileyo ayinamsebenzi, kodwa kubalulekile ukuba kuqatshelwe izibalo ezichanekileyo).
- Ukujikeleza kwangoko kakhulu. Gcina ukuchaneka okupheleleyo ngokubala uze ujikeleze kuphela impendulo yokugqibela. Ukujikeleza amanyathelo aphakathi kunokwenza iimpazamo.

Ukuqukumbela
Ukubala ubunzima bephepha le-aluminiyam sisixhobo esilula kodwa esiyimfuneko kuye nabani na othengayo, uyathengisa, okanye wenza ialuminiyam. Ngefomula Ubunzima = Ubude × Ububanzi × Ukutyeba × Ubuninzi, itafile yoxinaniso lwealloyi, kunye neetshathi zereferensi ekhawulezayo ngasentla, Ungabala nabuphi na ubungakanani bephepha ngemizuzwana - akusekho ukuqikelela okanye ukuthembela kumanani aqikelelwayo abaxhasi.
Kwi-Eco Alum, sinikezela ngamaphepha e-aluminiyam kwii-alloys 1050, 1060, 1100, 3003, 5005, 5052, 5083, 5754, 6061, kunye nokuninzi, kumgangatho we-4×8, 4×10, kunye neesayizi zesiko ukusuka 0.5 mm ukuya 200 mm ubukhulu. Yonke into ethunyelwayo ibandakanya isatifikethi sovavanyo lwezinto eziphathekayo (MTC) ngobungqingqwa obulinganisiweyo kunye nobunzima. Qhagamshelana nathi ngekowuti ekhuphisanayo kwiodolo yakho elandelayo.
