Txoj kev sib xyaw ua ke ntawm daim txhuam cev yog txheej txheem ntawm cov organic sib txuas cov ntxeem tau, elastic ua npuas ncauj nrog cov ntaub ntaub. Nws cov tub ntxhais nyob rau hauv qhov tseeb proportioning ntawm raw cov ntaub ntawv thiab cov txheej txheem tswj los tsim ib tug ruaj khov, functionally complementary composite qauv ntawm lub npuas txheej thiab cov ntaub nto. Txoj kev no suav nrog cov theem tseem ceeb xws li kev npaj ua npuas ncauj, ntaub pretreatment, kev sib xyaw ua ke, thiab ua tiav. The process selection and technical parameters at each stage directly affect the density uniformity, resilience, interlayer bonding strength, and appearance quality of the finished product.
Kev sib xyaw ntawm cov npuas npuas feem ntau yog siv cov tshuab ua npuas ncauj polymer, nrog polyurethane thiab polyvinyl cawv yog cov tshuab siv ntau tshaj plaws. Polyurethane ua npuas ncauj yog tsim los ntawm polymerization thiab foaming cov tshuaj tiv thaiv ntawm polyols thiab isocyanates nyob rau hauv qhov kev txiav txim ntawm catalysts, foaming agents, thiab surfactants. Cov txheej txheem tsim khoom tuaj yeem muab faib ua ib qho - kauj ruam thiab ob - kauj ruam txoj hauv kev: Ib qho - kauj ruam txoj hauv kev suav nrog kev sib xyaw tag nrho cov ntaub ntawv raw ib zaug thiab txhaj rau hauv pwm lossis nruam foaming chav tsev, nrog cov tshuaj tiv thaiv thiab foaming ib txhij, tsim nyog rau loj ntau lawm ntawm homogeneous boards; the two-step method first prepares a prepolymer containing isocyanate, then mixes it with a foaming agent and other additives, allowing for more precise control of the cell structure and density, suitable for high-performance cushioning materials. Cov tshuaj tiv thaiv kub, nplawm tus nqi, thiab cov khoom siv raw cov khoom sib piv yuav tsum nruj me ntsis tswj kom tsis txhob muaj qhov pore loj, shrinkage deformation, los yog tsis txaus resilience. Polyvinyl cawv ua npuas ncauj siv PVA tov raws li ib tug matrix, ntxiv foaming agents thiab crosslinking agents, thiab yog tsim los ntawm cua sov los yog khov, ziab, thiab kho. Nws cov txheej txheem synthesis muab qhov tseem ceeb dua rau kev tswj cov dej noo thiab kev hloov pauv ntawm crosslinking℃kom tau txais cov softness thiab biodegradability.
Pretreatment ntawm cov ntaub saum npoo yog ib kauj ruam ua ntej hauv kev sib xyaw ntawm daim txhuam cev. Nyob ntawm seb hom fiber ntau siv (paj rwb, polyester, nylon, los yog blends), tsim nyog desizing, refining, tshav kub, los yog tshuaj kho kev kho mob yuav tsum tau tshem tawm impurities, stabilize qhov ntev, thiab optimize nto zog thiab nplaum zog. Piv txwv li, polyester fabrics muaj peev xwm muaj lawv nto roughness txhim kho los ntawm alkali txo kev kho mob, txhim khu lawv mechanical interlocking nrog lub npuas txheej; cov ntaub paj rwb tuaj yeem ua rau lub teeb resin tiav los txhim kho cov dej tsis kam thiab kev tiv thaiv wrinkle, tiv thaiv deformation lossis pilling thaum lamination thiab post- ua.
Lamination yog cov kauj ruam tseem ceeb hauv kev sib txuas ntawm daim txhuam cev, feem ntau muaj peb txoj hauv kev: nplaum nplaum, kub nias, thiab stitch weaving. Hauv cov nplaum nplaum, ua npuas dej thiab ntaub yog txheej thiab coated nrog cov kuab tshuaj -raws li lossis dej-raws li ib puag ncig tus phooj ywg adhesives. Cov nplaum txheej yog tom qab ntawd kho nyob rau hauv qhov tshwj xeeb kub thiab siab siv cov chais los yog lub tshuab vulcanizing tiaj tus, ua tiav interlayer bonding. Txoj kev no yog cov paub tab thiab siv tau dav, tab sis nws yuav tsum muaj kev ua haujlwm siab hauv kev tswj cov tuab thiab kev sib xws ntawm cov nplaum txheej kom tsis txhob cuam tshuam rau kev ua pa thiab softness. Kub nias siv cov yam ntxwv me ntsis melting ntawm cov npuas dej hauv qab cua sov kom cuam tshuam nrog cov ntaub fibers, tshem tawm qhov xav tau rau cov nplaum ntxiv. Nws tuav cov qauv ntxeem tau ntawm cov khoom siv thiab txhim kho ib puag ncig tus phooj ywg, tab sis kev tswj xyuas qhov kub thiab txias, siab, thiab lub sijhawm yog qhov tseem ceeb los tiv thaiv kev ua npuas ncauj lossis ntaub scorching. Txoj hlua khi- txoj kev sib khi mechanically intertwines ntaub thiab ua npuas ncauj los ntawm rab koob xuas nrig ntaus lossis ib lub plooj- lub tshuab sib txuas, tsim cov khoom sib txuas uas sib txuas ua ke nrog lub zog ua pa. Txoj kev no yog tsim rau cov khoom siv tiv thaiv uas xav tau siab tensile thiab tsim kua muag. Txawm li cas los xij, kev saib xyuas yuav tsum tau ua nrog rau qhov sib txawv ntawm qhov sib txawv thiab rab koob punching qhov tob kom tsis txhob ua rau cov npuas dej ua kom muaj zog.
Ncej -kev ua haujlwm ua lub luag haujlwm hauv kev ua kom zoo dua qub thiab nthuav dav ua haujlwm thaum lub sijhawm ua ke. Kev ntxhib los mos ntawm qhov chaw thiab qhov chaw ua pa tuaj yeem hloov kho los ntawm embossing thiab laser perforation; antibacterial, anti-mildew, nplaim taws-retardant, los yog waterproof txheej yuav siv tau los siv padding los yog tshuaj tsuag kom tau raws li qhov yuav tsum tau ntawm ib puag ncig tshwj xeeb; kev txhuam hniav los yog txheej txheej tuaj yeem ua tau thaum tsim nyog los txhim kho qhov kev xav lossis tiv thaiv cov dej nkag. Thaum kawg, precision txiav nrog rab riam txias lossis kub yields cov khoom tiav ntawm qhov xav tau tshwj xeeb thiab cov duab.
Quality control is maintained throughout the entire synthesis process, including raw material viscosity and reactivity testing, foam density and pore size analysis, interlayer peel strength testing, and evaluation of finished product resilience and breathability to ensure the sponge fabric's stable and reliable performance in different application scenarios.
Hauv cov ntsiab lus, txoj kev sib txuas ntawm daim txhuam cev yog ua raws li polymer foaming thiab textile pretreatment. Nws ua tiav kev sib xyaw ua ke ntawm cov npuas dej thiab cov ntaub los ntawm ntau yam - cov txheej txheem sib xyaw ua ke, thiab tuaj yeem txhim kho ntxiv nrog kev ua haujlwm tiav kom nthuav dav thaj tsam kev ua haujlwm. Cov txheej txheem txheej txheem no tsis tsuas yog ua kom muaj kev nplij siab thiab ua haujlwm ntev ntawm cov khoom siv tab sis kuj muab cov kev daws teeb meem tsim nyog thiab tsim kom muaj peev xwm rau ntau yam kev xav tau hauv khau, khaub ncaws, rooj tog hauv tsev, kev kho mob, thiab kev siv tiv thaiv kev lag luam.
