Cov ntsiab lus tseem ceeb thiab kev tsom xam ntawm Inflatable Fabric Material Selection
Raws li cov ntaub ntawv tseem ceeb ntawm cov ntaub ntawv niaj hnub science, inflatable fabrics ncaj qha cuam tshuam cov khoom ua tau zoo thiab lifespan. Inflatable fabrics yog siv dav hauv cov khoom siv sab nraum zoov, cov khoom siv kho mob, thiab cov khoom siv lom zem thiab lom zem vim lawv lub teeb yuag, txav tau yooj yim, thiab ua haujlwm. Kab lus no tshawb nrhiav cov tswv yim xaiv cov khoom siv rau cov ntaub npuag los ntawm peb qhov kev xav: cov khoom siv, kev ua haujlwm, thiab kev hloov pauv ib puag ncig.
Los ntawm cov khoom siv yooj yim, cov ntaub npuag niaj hnub no feem ntau siv cov polymers ua lawv cov khoom siv raw. Polyurethane (PU)-coated fabrics, vim lawv zoo heev elastic modulus thiab abrasion kuj, tau dhau los ua cov khoom nyiam rau nruab nrab - mus rau siab - khoom kawg. Cov khoom siv no tswj tau zoo heev airtightness thaum tiv thaiv cov neeg kho tshuab kev ntxhov siab ntawm kev nce nyiaj rov qab thiab deflation. Hauv kev sib piv, polyethylene (PE) zaj duab xis, thaum tsis tshua kim, raug kev txom nyem los ntawm qhov tsis muaj zog ductility thiab tsis txaus puncture resistance, ua rau nws tsis haum rau cov ntawv thov uas yuav tsum tau siv sijhawm ntev -. Qhov tshwj xeeb, qhov tshwm sim ntawm cov khoom siv thermoplastic polyurethane tshiab (TPU) tau txhim kho lawv cov huab cua tsis kam thiab kev ua haujlwm ib puag ncig los ntawm kev ua kom zoo ntawm cov qauv molecular, nrog lub voj voog degradation kwv yees li 40% luv dua li cov khoom siv PU.
Kev ua haujlwm -kev xaiv cov khoom siv yuav tsum ua qhov tseem ceeb ntawm cov kev cai tshwj xeeb ntawm qhov kev npaj siv. Nyob rau hauv lub tshav pob ntawm sab nraum zoov cawm, cov cuab yeej xws li inflatable stretchers yuav tsum tau fabrics uas muaj zog thiab breathable. Ib ob - txheej txheej txheej txheej yog ib qho kev daws teeb meem zoo: 210D nylon puag ntaub rau txheej txheej txhim khu kua muag, thaum lub microporous PU zaj duab xis yog siv nyob rau hauv txheej sab hauv los pab txhawb kev sib pauv roj. Rau cov khoom siv ua kis las dej, xws li lub tsho lub cev muaj zog, kev xaiv cov khoom siv yuav tsum ua qhov tseem ceeb ntawm qhov sib npaug ntawm buoyancy thiab tawv nqaij - kev xav zoo. Feem ntau, kaw-cell EVA ua npuas ncauj nrog qhov ceev ntawm 0.91 g / cm³ yog laminated nrog PVC-coated ntaub. Qhov no ua kom lub ntim ntim ntawm 0.024 m³ thaum txhawb kev nplij siab los ntawm kev ntxhib los mos. Kev kho mob huab cua txaj qhov chaw txawm xav tau ntau dua ntawm cov khoom siv biocompatibility. Kev kho mob- qib silicone- cov ntaub coated, vim lawv cov khoom tsis yog{17}}allergenic thiab sterilizable, tau dhau los ua qauv hauv tsev kho mob.
Environmental adaptability yog ib qho tseem ceeb ntawm kev siv cov khoom siv. Sunscreen coatings nrog ib qho Ultraviolet Protection Factor (UPF) ntawm 50+ tuaj yeem ua kom cov txheej txheem kev laus ua haujlwm tau zoo nyob rau hauv qhov siab - qhov chaw tshav ntuj. Rau polar low-tej daim ntawv thov kub, hloov kho roj hmab matrix infused nrog boron carbide nanoparticles tuaj yeem txo nws qhov kub thiab txias kom qis dua -40 degree, kom ntseeg tau yooj yim nyob rau hauv huab cua txias. Nyob rau hauv ib puag ncig marine, composite fabrics kho nrog triple kev tiv thaiv (anti-mildew, anti- ntsev tsuag, thiab anti-algae) tuaj yeem ua tiav qhov kev sib cuag ntawm cov ces kaum siab tshaj 115 degree, txo tus nqi ntawm seawater yaig. Cov ntaub ntawv kuaj pom tau hais tias tom qab 500 teev ntawm kev tso dej hauv qab dej, cov pa roj pa ntawm nano-hydrophobic kho cov ntaub tseem nyob hauv 3% ntawm tus nqi pib.
Cov khoom siv tshiab yog tsav kev ua haujlwm tsis tu ncua hauv inflatable fabric technology. Kev tshawb fawb thiab kev tsim kho bio-raws li polyurethanes tau ua tiav thawj zaug. Ib tiam tshiab ntawm cov ntaub ntawv tsim los ntawm cov roj cog muaj 62% qis dua cov pa roj carbon hneev taw thaum tuav cov khoom siv sib piv rau cov tshuaj polyurethane. Kev siv lub cim xeeb polymers muab nws tus kheej - kho cov khoom rau cov ntaub. Thaum kuaj pom tias micro- puas tsawg dua 0.5 hli, cov ntaub tuaj yeem kho tau los ntawm kev rov ua lawv cov saw hlau molecular los ntawm cov cua sov hauv zos. Txoj kev loj hlob ntawm kev txawj ntse siab- tswj cov ntaub ntawv suav nrog cov duab cim xeeb alloy fiber ntau uas tau hloov kho qhov qhib thiab kaw ntawm qhov cua raws li kev hloov pauv ntawm lub siab nyob ib puag ncig. Cov thev naus laus zis no tau nkag mus rau theem kev sim teb hauv kev lag luam aerospace.
Kev txiav txim siab txog kev tshawb fawb- kev xaiv cov khoom yuav tsum muaj kev ntsuam xyuas qhov system. Kev ntsuam xyuas tau pom zoo thoob plaws peb theem: kev sim cov cuab yeej hauv lub cev (xws li lub zog tensile Ntau dua lossis sib npaug ntawm 200N / 5cm thiab lub zog tsim kua muag Ntau dua lossis sib npaug rau 50N), kev ua haujlwm pov thawj (airtightness test: tswj siab rau siab dua lossis sib npaug li 24 teev tsis muaj kev poob siab), thiab ua kom lub cev muaj zog ntawm 7 teev (2 teev) xyoo ntawm natural aging). Rau kev yuav khoom ntau, me me - qauv ntsuas kev hloov pauv ib puag ncig yuav tsum tau ua, suav nrog kev caij tsheb kauj vab kub ntawm -30℃txog 70℃thiab kev sim ua haujlwm ntawm 85% av noo.
Tam sim no, kev xaiv ntawm cov ntaub npuag inflatable tau hloov pauv los ntawm ib qho - kev ua tau zoo mus rau ntau - qhov ua tau zoo sib npaug. Nrog rau kev nce qib hauv cov ntaub ntawv tshawb fawb, kev txhim kho yav tom ntej yuav tsom mus rau kev sib koom ua kom zoo ntawm lub teeb yuag thiab lub zog siab, qhov loj - daim ntawv thov ntawm ib puag ncig tus phooj ywg cov ntaub ntawv, thiab kev sib xyaw tsim ntawm cov lus teb ntse. Thaum xaiv cov ntaub npuag, cov neeg siv khoom siv yuav tsum tsim ib qho peb - qhov kev txiav txim siab loj - ua qauv uas suav nrog cov khoom siv tsis zoo, tus nqi- kev ua tau zoo, thiab ib puag ncig raws li qhov tseem ceeb ntawm kev ua haujlwm ntawm cov ntawv thov tshwj xeeb, yog li ua tiav qhov kev pom zoo ntawm cov khoom ua tau zoo thiab cov nqi siv tau.
