Txij li cov khoom siv niaj hnub mus rau cov kev daws teeb meem kev lag luam siab heev, cov polymers nyob txhua qhov chaw
Hauv lub ntiaj teb dav dav thiab nyuaj ntawm kev tshawb fawb txog cov ntaub ntawv, muaj ob peb lo lus uas siv tau thoob plaws tab sis tsis nkag siab zoo li "yas." Hauv kev tshawb fawb, plastics yog ib pawg ntawm ib pawg dav dua thiab txaus nyiam dua:Cov polymersCov molecule ntev no, tsim los ntawm kev rov ua dua cov chav me me hu uacov monomers, yog cov txha nqaj qaum ntawm kev tsim khoom siv niaj hnub no, muab kev sib xyaw ua ke tsis muaj qhov sib piv ntawmkev ua tau ntau yam,kev ua tau ntev, thiabkev tsim khoom.
Cov polymers nyob txhua qhov chaw. Lub raj mis dej ntawm koj lub rooj, lub plhaub ntawm koj lub xov tooj ntse, cov fibers hauv koj cov khaub ncaws, thiab cov khoom hauv koj lub tsheb txhua yam vam khom cov ntaub ntawv polymeric. Lawv cov khoom tuaj yeem kho kom zoo - los ntawm kev ywj pheej thiab pob tshab mus rau tawv thiab tsis pom kev - los ntawm kev hloov pauv lawv cov qauv tshuaj lom neeg thiab cov txheej txheem ua. Qhov kev hloov pauv no tau ua rau cov polymers tseem ceeb thoob plaws hauv cov lag luam, suav nrogkev kho mob,kev tsim kho,tsheb, thiabkhoom siv hluav taws xob.
Txawm li cas los xij, tsis yog txhua cov polymers raug tsim sib npaug.cov khoom sib xyaw ua ke, uas sib xyaw ua kecov polymersnrogcov ntaub ntawv txhawb zog, tau qhib cov ciam teb tshiab hauv kev ua tau zoo. Qhov no yog qhov uas tau tsim loscov ntaub scrimua lub luag haujlwm tseem ceeb. Ascrimyog ib daim ntaub mesh qhib uas sib dua thiab siv los muabkev txhawb nqa cov qauv,kev ruaj khov, thiabkev sib xwshauv cov ntaub ntawv sib xyaw.
Sau cov khoom tshiab xws li Fiberglass Laid ScrimCov khoom siv no siv cov khoom siv zoo, thiab muab tso rau qhov chaw raug.cov fiberglass filamentssib txuas ua ke rau hauv ib lub network zoo li grid. Thaum koom ua ke rau hauvcov polymer matrix, nws muab kev pabcuam zoo heevkev ruaj khov ntawm qhov ntev,lub zog tensile, thiabkev tiv thaiv kubua rau nws zoo tagnrho rau cov ntawv thov hauvcov ntaub thaiv ru tsev,cov txheej txheem hauv pem teb, thiabcov hniav cua turbineNws qhov qhib weave tso cai rau kev ua haujlwm zookev nkag mus rau hauv cov roj hmab, xyuas kom meej tias muaj zog, sib xyaw ua ke.
Ib yam li ntawd,Polyester Laid Scrimsiv cov yam ntxwv uas muaj nyob hauvkev ua siab tawvthiabkev tiv thaiv tshuaj lom neegntawmcov khoom siv polyesterQhov scrim variant no yog tshwj xeeb tshaj yog muaj nqis rau nwskev hloov pauv tau yooj yim,tsis kam dej noo, thiabkev ua tau ntevNws yog siv dav hauv kev txhawb nqa ntawmcov khoom sib xyaw ua ke yooj ywm, xws licov ntaub thaiv dej,cov ntaub marine,cov ntaub thaiv pas dej ua ke, thiab qee homcov ntaub thaiv dej tsis nkag hauv tsevCov polyester fibers muab ib lub scaffold robust uas txhim kho qhovkua muagthiabtsis kam rau qhov thontawm cov khoom kawg yam tsis ntxiv qhov hnyav tseem ceeb.
Kev tsim cov ntaub ntawv tshwj xeeb no qhia txog qhov tseem ceeb hauvkev tsim khoom siv: txav mus dhau cov yas dav dav mus raukev ua tau zoo heev,cov kev daws teeb meem tshwj xeeb rau daim ntawv thov. Cov khoom zoo liFiberglass Laid ScrimthiabPolyester Laid Scrim ua piv txwv li cas qhov kev tshawb fawb tseem ceeb ntawmcov polymersraug siv thiab txhim kho kom daws tau cov teeb meem hauv ntiaj teb tiag. Lawv hloov cov qauv yas yooj yim mus rau hauvcov khoom sib xyaw ua kemuaj peev xwm ua tau raws li qhov xav tau nruj raulub zog,lub neej ntev, thiabkev tiv thaiv ib puag ncig.
Raws li kev lag luam txuas ntxiv mus zuj zus, tsom mus raukev ruaj khovthiabkev siv dua tshiab, lub luag haujlwm ntawmcov polymersthiab lawv cov khoom sib xyaw ua ke uas muaj zog dua los ua qhov tseem ceeb dua. Yav tom ntej nyob rau hauv kev tsimntse dua,ntsuab dua, thiab cov ntaub ntawv ua tau zoo dua, kom ntseeg tau tias kev hloov pauv polymer txuas ntxiv mus rau hauv peb lub ntiaj teb hauv txoj kev tob thiab zoo.
