EVA (ethylene vinyl acetate) cov tsev nyob tau dhau los ua neeg nyiam vim lawv cov khoom tsis muaj dej tsis zoo thiab tsis muaj zog. Cov rooj plaub no tau siv dav los tiv thaiv cov khoom siv hluav taws xob, lub koob yees duab, thiab lwm yam khoom muag los ntawm dej, plua plav, thiab kev cuam tshuam. Cov txheej txheem tsim khoom ntawm cov dej tsis muaj dej thiab muaj zog EVA muaj ob peb kauj ruam tseem ceeb los xyuas kom meej tias cov khoom kawg ua tau raws li cov qauv zoo tshaj plaws. Hauv tsab xov xwm no, peb yuav tshawb txog cov txheej txheem tsim khoom ntawm awaterproof thiab muaj zog EVA rooj plaub, los ntawm kev xaiv cov khoom siv mus rau kev tshuaj xyuas cov khoom kawg.
Kev xaiv khoom
Kev tsim cov dej tsis zoo thiab ruaj khov EVA tiv thaiv rooj plaub pib nrog kev xaiv cov khoom zoo EVA. EVA yog copolymer ntawm ethylene thiab vinyl acetate, tsim cov khoom siv ruaj khov, hloov tau yooj yim, thiab tsis muaj dej tsis zoo. Cov txheej txheem xaiv cov khoom suav nrog xaiv cov qib tsim nyog ntawm EVA kom ua tau raws li cov kev cai tshwj xeeb ntawm cov ntaub ntawv tsis muaj dej tsis zoo thiab cov ntaub ntawv rugged. Cov khoom siv EVA yuav tsum muaj qhov sib npaug zoo ntawm qhov tawv thiab yooj yim los muab kev tiv thaiv siab tshaj plaws rau cov ntsiab lus.
Moulding
Thaum cov khoom siv EVA raug xaiv, cov kauj ruam tom ntej hauv kev tsim khoom yog txheej txheem molding. Cov khoom siv EVA yog rhuab thiab txhaj rau hauv pwm los tsim cov ntaub ntawv saib hauv qhov xav tau thiab loj. Cov pwm yog ua tib zoo tsim los xyuas kom meej meej haum nrog cov khoom siv hluav taws xob lossis lwm yam khoom muaj nyob hauv lub thawv. Cov txheej txheem molding yog qhov tseem ceeb rau kev ua tiav cov khoom tsis muaj dej tsis zoo thiab rugged ntawm EVA plhaub, vim nws txiav txim siab tag nrho cov qauv thiab kev ncaj ncees ntawm cov khoom kawg.
Sealing thiab sib txuas
Tom qab molding cov khoom EVA rau hauv cov duab xav tau, cov kauj ruam tom ntej yog sealing thiab gluing. Waterproof EVA vaj tse yuav tsum muaj lub foob airtight los tiv thaiv dej thiab plua plav nkag mus rau hauv tsev. Siv cov txheej txheem tshwj xeeb sealing xws li kev siv vuam ntau zaus lossis kev sib khi thaum tshav kub kub los tsim cov seams thiab cov pob qij txha. Tsis tas li ntawd, cov txheej txheem kev sib txuas yog siv los txhim kho cov txheej txheem kev ncaj ncees ntawm rooj plaub, kom ntseeg tau tias nws tuaj yeem tiv taus qhov cuam tshuam thiab kev tuav tsis zoo.
Reinforcement thiab padding
Txhawm rau txhim kho qhov ruaj khov ntawm EVA plhaub, cov khoom siv ntxiv thiab cov khoom ntim tau ntxiv thaum lub sijhawm tsim khoom. Cov ntaub ntawv txhawb zog xws li nylon lossis fiberglass tau muab tso rau hauv cov qauv EVA kom muaj zog ntxiv thiab nruj. Padding cov ntaub ntawv xws li ua npuas ncauj lossis velvet hauv ob sab phlu kuj yog siv los cushion thiab tiv thaiv cov khoom nyob rau hauv lub khob thiab khawb. Kev sib xyaw ua ke ntawm kev txhawb nqa thiab padding kom ntseeg tau tias EVA rooj plaub muab kev tiv thaiv siab tshaj plaws thaum tuav nws lub teeb yuag thiab txav tau yooj yim.
Kev Ntsuas thiab Kev Tswj Xyuas Zoo
Thaum cov txheej txheem tsim khoom tiav lawm, lub plhaub EVA tsis muaj dej tsis zoo thiab ruaj khov yuav raug kuaj nruj thiab ntsuas kev tswj xyuas zoo. Ntau yam kev ntsuam xyuas, suav nrog kev sim dej rau hauv dej, kev sim cuam tshuam, thiab kev sim ua kom ntev, yog ua los xyuas kom meej tias cov ntaub ntawv ua tau raws li cov qauv kev tiv thaiv dej thiab ruggedness. Kev tswj xyuas kev ua tau zoo yog ua los xyuas seb puas muaj qhov tsis zoo lossis qhov tsis zoo hauv lub thawv, kom ntseeg tau tias tsuas yog cov khoom lag luam zoo raug tso tawm rau hauv khw.
Kev tshuaj xyuas cov khoom kawg
Cov kauj ruam kawg hauv cov txheej txheem tsim khoom yog kev tshuaj xyuas ntawm lub thawv EVA tiav. Txhua lub thawv tau ua tib zoo tshuaj xyuas rau txhua qhov kev tsim khoom tsis xws luag, xws li cov seams tsis sib xws, cov pob qij txha tsis muaj zog, lossis tsis muaj dej tsis txaus. Cov txheej txheem tshuaj xyuas kuj suav nrog kev tshuaj xyuas tag nrho cov kev zoo nkauj thiab kev ua haujlwm ntawm lub thawv kom ntseeg tau tias lawv ua tau raws li cov qauv tsim nyog rau kev tiv thaiv dej tsis zoo thiab ruaj khov. Txhua qhov teeb meem tsis zoo yuav raug txheeb xyuas thiab kho ua ntej yuav ntim thiab xa mus rau tus neeg siv khoom.
Hauv cov ntsiab lus, kev tsim cov dej tsis muaj dej thiab muaj zog EVA muaj cov txheej txheem ua kom zoo uas suav nrog kev xaiv cov khoom siv, molding, sealing thiab gluing, reinforcement thiab filling, testing and quality control, and final products inspection. Los ntawm kev ua raws li cov qauv zoo nruj thiab siv cov thev naus laus zis tsim khoom, cov tuam txhab tuaj yeem ua kom ntseeg tau tias EVA cov ntaub ntawv muaj cov dej tsis zoo thiab ruaj khov, muab kev tiv thaiv zoo rau cov khoom muaj nqis hauv ntau qhov chaw. Raws li cov neeg siv khoom xav tau kom ruaj khov, cov kev daws teeb meem dej tsis zoo txuas ntxiv zuj zus, kev tsim cov thawv EVA zoo tseem ceeb heev kom ua tau raws li cov kev xav tau no.
