Kev tsim cov kua muag-resistant hnab xa ntawv yuav tsum tau ua kom zoo zoo hauv kev xaiv cov khoom siv, kev ua kom zoo dua qub, tsim qauv tsim thiab kev tshuaj xyuas. Cov hauv qab no yog cov kauj ruam tshwj xeeb thiab cov txheej txheem:
1. Kev xaiv cov khoom siv
Cov khoom siv yog tus yuam sij rau kev txiav txim siab qhov zoo ntawm lub hnab ntim khoom tsim kua muag.
HDPE (high-density polyethylene): siab toughness thiab puncture tsis kam, haum rau lub hnab uas yuav tsum tau tsim kua muag siab.
LLDPE (linear low-density polyethylene): zoo elasticity thiab tensile zog, ua kom tsim kua muag.
Elastomer cov ntaub ntawv (xws li EVA, TPU): txhim khu kev yooj yim thiab cuam tshuam, txo qhov kev pheej hmoo ntawm kev tsim kua muag.
Cov khoom siv rov ua dua tshiab thiab cov khoom siv raw sib xyaw: Rau ib puag ncig tus phooj ywg lub hnab xa ntawv, ib feem ntawm cov khoom siv rov ua tau zoo tuaj yeem muab ntxiv rau hauv cov mis, thiab xyuas kom meej tias nws tsis txo qhov tsim kua muag ntawm lub hnab.
2. Optimize ua technology
Kev siv thev naus laus zis ncaj qha cuam tshuam rau kev tsim kua muag ntawm cov hnab xa ntawv:
Multi-layer co-extrusion technology: Muab qhov zoo ntawm cov khoom sib txawv los ntawm ntau txheej txheej, xws li txheej txheej tensile tsis kam thiab sab hauv tsim kua muag.
Stretch orientation technology: Ua uniaxial los yog biaxial orientation kho nyob rau hauv zaj duab xis ntau lawm ua rau cov molecular chains ntau zoo sib xws thiab txhim khu lub mechanical zog ntawm lub hnab.
Thickness uniformity tswj: Ua kom cov yeeb yaj kiab tuab tuab los ntawm cov khoom siv high-precision extrusion los txo qhov kev pheej hmoo ntawm kev tsim kua muag ntawm cov ntsiab lus tsis muaj zog.
High-pressure molding txheej txheem: Txhim kho qhov ntom ntawm zaj duab xis thiab qhov zoo ntawm cov saw hlau molecular, txhim khu nws lub zog thiab ua haujlwm ntev.
Thaum tshav kub kub sealing zog optimization: xyuas kom meej tias lub hnab lub qhov ncauj sealing ib feem muaj txaus tsim kua muag los ntawm kev kho lub tshav kub foob kub thiab siab.
3. Tus qauv tsim
Cov qauv tsim ntawm lub hnab xa ntawv ncaj qha cuam tshuam rau nws cov kua muag tsis kam.
Thickening tseem ceeb qhov chaw: Lub zos thickening tsim ntawm lub hnab lub qhov ncauj, hauv qab los yog kev ntxhov siab-nrhiav qhov chaw kom tsis txhob tearing los ntawm concentrated siab.
Ob-txheej ntug foob tsim: Txhim kho lub zog ntawm ntug foob los ntawm ob txheej txheej thaum tshav kub kub sealing los yog ntau txheej lamination.
Tear-resistant qauv tsim: Tsim cov qauv concave thiab convex nyob rau saum npoo ntawm lub hnab los txhim kho lub tensile thiab kua muag tsis kam ntawm qhov chaw.
Zipper lossis adhesive daim kab xev txhim kho: Siv cov zippers muaj zog lossis cov nplaum nplaum los xyuas kom meej tias lub foob tsis yooj yim los tsim kua muag thaum thauj.
Aviation qhov tsim: Ntxiv cov vents me me kom tawg lub siab hauv lub hnab kom tsis txhob muaj kua muag vim lub siab sab hauv.
4. Ntxiv cov khoom siv ntxiv
Txhim kho cov khoom siv los ntawm kev ua haujlwm additives:
Tear-resistant enhancers: xws li nanofibers lossis carbon fibers, txhim kho lub zog tsim kua muag thiab ductility ntawm cov ntaub ntawv.
Slip agents: txo kev sib txhuam ntawm qhov chaw ntawm cov khoom kom tsis txhob tawg los ntawm kev sib txhuam puas.
Anti-aging additives: ncua lub neej kev pab cuam ntawm lub hnab thiab tsis txhob aging ua rau ib tug txo nyob rau hauv tearing kev ua tau zoo.
Barrier additives: txhim kho cov kua qaub, alkali thiab noo noo tsis kam ntawm cov khoom, thiab txo cov kua muag los ntawm cov tshuaj tiv thaiv thaum lub caij tsheb thauj mus los.
5. Kev tshuaj xyuas thiab kev tswj xyuas zoo
Tear lub zog kuaj: siv cov cuab yeej los ntsuas cov kua muag tsis kam ntawm zaj duab xis nyob rau hauv cov lus qhia longitudinal thiab transverse.
Puncture lub zog kuaj: txheeb xyuas qhov ua tau zoo ntawm lub hnab xa ntawv thaum nws cuam tshuam los ntawm cov khoom ntse.
Kev simulation kev thauj mus los tiag tiag: simulate cov txheej txheem ntim khoom thiab kev thauj mus los los xyuas cov kua muag tsis kam ntawm lub hnab nyob rau hauv siab, kev co thiab extrusion.
Thaum tshav kub kub foob lub zog kuaj: xyuas kom meej tias lub foob tsis yooj yim rau tsim kua muag thaum lub sij hawm thauj mus los thiab ntau qhov qhib.
Lub hnab xa ntawv nrog lub zog tsim kua muag yuav tsum muaj kev sib koom tes ntau qib.
