Tsoos loj foaming ntawm tiaj tiaj tam sim no feem ntau siv cov txheej txheem no nyob rau hauv cov tsev lag luam me me, thiab cov cuab yeej siv nqi yog tsawg. Cov txheej txheem zoo li no yog ua los ntawm cov phaj, uas tseem yuav tsum tau tsim rau hauv cov khoom los ntawm cov txheej txheem xws li kev xuas nrig ntaus thiab sawv. EVA cov khoom siv ua los ntawm cov khoom npuas EVA muaj qhov hloov tau yooj, poob siab tsis kam, tiv thaiv nplua, thiab muaj zog tiv taus lub siab. Lawv dav siv hauv cov khau khau kev lag luam, kev lag luam ntim khoom, khoom siv hluav taws xob, khoom siv kho vajtse, khoom siv kis las, cov khoom ua si thiab lwm cov teb. Xws li peb cov khau khiab EVA uas niaj hnub tuaj yeem, EVA ntim hlua khi, EVA txawb xov tooj tiv thaiv npog, EVA welt, EVA ntab pawg, EVA tiv thaiv lub kaus mom hlau thiab lwm yam khoom lag luam txhua hnub.
Dej tsis ua npuas ncauj daim kab xev yog ib hom ntawm tus kheej kheej qhov cub pleev cov kua dej ua los ntawm EVA ua cov khoom tseem ceeb, nrog rau lwm cov tshuaj ntxiv, thiab ua tiav los ntawm cov thev naus laus zis siab. Nws muaj cov nplaum muaj zog rau saum npoo ntawm ntau cov ntaub ntawv. Nyob rau tib lub sijhawm, nws muaj huab cua zoo tiv thaiv, laus tiv taus thiab dej tsis kam, thiab muaj cov haujlwm ntawm kev sib khi, zas thiab tiv thaiv cov nplaim ib puag ncig. Vim tias nws tsis muaj cov kuab tshuaj, nws tsis xau lossis tawm cov roj lom; vim tias nws tsis ua kom ruaj khov rau lub neej, nws muaj txoj kev ua tiav zoo rau kev ua kom thermal nthuav dav thiab muaj qhov cuam tshuam ntawm cov nplaim thiab cov tshuab deformation. Nws yog cov khoom siv qib siab tshaj plaws. Cov yam ntxwv ntawm cov dej tsis zoo ua npuas ncauj kab xev:
Cov xim sib txawv ntawm EVA ko taw cov khoom, hluav taws kub EVA, ib puag ncig tus phooj ywg EVAPORON pawm, EPDM, iav ntim cov roj av, cov hlaws paj rwb, cov paj rwb paj rwb cov khoom lag luam, cov roj pleev, cov khoom siv paj rwb, cov nplaum tshwj xeeb, cov khoom tsis haum, thiab lwm yam Raws li cov kev xav tau ntawm sib txawv cov neeg muas zaub, ntau yam kev tshwj xeeb ntawm cov khoom tau txais kev cai.
1: Lub hom phiaj tseem ceeb: ua si lub luag hauj lwm cais nyob rau hauv lub khob cia thiab thauj tus txheej txheem, kho qhov kev ncua deb, tiv thaiv lub khob thiab lub khob los ntawm kev sib cuag, kev sib tsoo, khawb, tawg thiab tawg, thiab lwm yam, zoo tiv thaiv lub khob, ua rau tsis muaj pa. Cov khoom tiv thaiv: tempered, hollow, laminated, coated, bulletproof thiab lwm yam iav ua tiav: 2: Khoom nta: zoo nkauj, huv si thiab tsis muaj qhov-dawb, muaj kev nyab xeeb, txhim kho yooj yim, tuaj yeem yooj yim rau ntawm iav rau lub sijhawm ntev, thiab yooj yim tshem tawm, Txawm hais tias tom qab lub siab hnyav, nws yuav tsis tawm ib txoj lw thaum nws dua, thiab yuav tsis muaj qhov seem
EVA ua npuas ncauj ob-daim nplaum kua nplaum yog cov yob zoo li tus nplaum nplaum ua los ntawm daim ntawv, daim ntaub, thiab EVA zaj duab xis ua cov khoom siv hauv paus, thiab tom qab ntawd zoo li txheej nrog elastomer siab-kua nplaum lossis tawv-ua kua-rhiab nplaum nplaum rau saum toj no- hais los luj khoom. Nws muaj li ntawm peb ntu: puag yog khoom, nplaum, thiab tso daim ntawv (zaj duab xis). Raws li cov nplaum ua kom zoo, nws tuaj yeem muab faib ua cov kuab tshuaj kua nplaum (cov roj siv ob npaug rau cov kua nplaum), emulsion nplaum cov kab xev (dej raws li EVA muab ob npaug rau cov nplaum nplaum cov khoom lag luam), kub yaj nplaum nplaum cov kab xev, daim ntawv nplaum nplaum nplaum, thiab rov ua ntaub nplaum. Feem ntau, nws yog siv dav hauv tawv, npe, ntawv sau, khoom siv hluav taws xob, kho tsheb kho tsheb, kev lag luam khau, ntawv ua, khoom siv tes ua dhau los thiab muab tso rau, lwm yam. Muaj ntau hom EVA ua npuas dej npaws ua ob hom kab xev khoom: mesh EVA ob daim kab xev cov khoom lag luam, cov khoom siv EVA muab ob npaug rau cov kab xev, cov khoom kub ua kom zoo siab EVA ua ob daim kab xev, tsis yog-siv tus kheej daim kab xev EVA muab ob yam khoom, cov khoom seem tsis muaj daim kab xev EVA muab ob npaug rau daim kab xev cov khoom lag luam, daim ntaub so ntswg EVA muab ob npaug rau daim kab xev khoom, iav EVA muab ob npaug rau daim kab xev khoom, PET ob npaug rau daim kab xev, EVA ua npuas ob npaug rau daim kab xev khoom, thiab lwm yam, yog siv rau hauv cov txheej txheem ntau lawm ntawm txhua qho ntawm lub neej.
Dej tsis ua npuas ncauj daim kab xev muaj qhov sib xyaw ua kom zoo thiab lub zog tensile, zoo extensibility thiab elasticity, pab txhawb nqa muaj zog, thiab txoj kev ua kom ruaj khov rau qhov chaw ntxhib. Cov tuab tuab tuab, hloov tau yooj yim, haum rau qhov chaw sib txawv lossis nruj siv. Nws yog qhov tshwj xeeb tshaj yog tsim nyog rau kev sib khi ruaj ruaj qauv ntawm kev kho tsheb tsheb hauv cov khoom siv hluav taws xob. Siv cov ntaub nplaum ua npuas dej: Ua ntej thov cov ntaub nplaum, kom huv huv cov roj thiab hmoov av rau ntawm qhov chaw yuav raug txuas, ntxuav tawm lwm yam paug, thiab tom qab ntawd dua cov ntaub nplaum. Ua zoo rau lub ntiv tes lossis lwm yam pa phem. Raws li qhov loj me ntawm cov substrate yuav tsum tau dhau los, txiav tawm daim kab xev thiab nyem nws nyuaj tom qab nws dhau los. Qhov saum npoo thiab siab ntawm cov kab xev yuav tsum tau ua nrog qhov siab txaus. Cov nplaum siv lub zog ntawm cov kab xev yog qhov zoo rau 72 ~ 96 teev tom qab sib cog lus, thiab nws xav tau primer rau ntsej muag yas, roj hmab, txheej tshwj xeeb thiab lwm yam ntxiv.
