Daim txhuam cev yog cov khoom siv ua los ntawm high-molecular polymer matrix los ntawm cov txheej txheem foaming, muaj ob qho yooj yim thiab cov qauv ntxeem tau. Nws qhov kev ua tau zoo feem ntau nyob ntawm kev xaiv thiab kev faib ua feem ntawm cov khoom siv hauv paus. Kev nkag siab txog hom khoom tseem ceeb yuav pab kom ua tiav cov khoom xaiv thiab kev ua tau zoo hauv cov xwm txheej sib txawv.
Tam sim no, cov ntaub ntawv ntau tshaj plaws ntawm daim txhuam cev hauv kev lag luam tuaj yeem muab faib ua peb lub tshuab loj: polyurethane, polyvinyl cawv, thiab cov khoom siv fiber ntau. Ntawm lawv, polyurethane daim txhuam cev yog siv dav tshaj plaws. Nws yog tsim los ntawm cov tshuaj tiv thaiv ntawm isocyanate thiab polyol, thiab muaj cov yam ntxwv ntawm adjustable kaw -cell los yog qhib - cell qauv. Closed-cell type has a dense texture, good resilience, and strong resistance to compression deformation, and is often used in areas where high support is required, such as seat cushions and packaging cushioning. Qhib- hom cell muaj qhov sib txuas ntawm qhov pore zoo thiab kev nqus dej zoo thiab ua pa, thiab feem ntau yog siv rau hauv cov ntawv thov kom nkag mus sai thiab tso tawm, xws li ntxuav thiab so cov ntaub ntawv, cov ntaub ntawv lim, thiab hnav khaub ncaws kho mob.
Polyvinyl cawv sponge npuag siv polyvinyl cawv ua cov khoom tseem ceeb thiab yog tsim los ntawm cross- txuas foaming. Nws muaj cov yam ntxwv ntawm muaj zog hydrophilicity thiab zoo biocompatibility. Cov khoom no nthuav tawm sai sai thaum sib cuag nrog dej thaum tuav lub ntsej muag muag, ua kom pom kev maj mam thiab qis - ua kom khaus khaus hauv qhov xwm txheej xws li kev ntxuav kho mob, ntsuas ntsuas qhov tseeb, thiab tshem tawm kom zoo nkauj. Nws kuj yog ib qho yooj yim biodegradable, ua raws li cov qauv ntawm cov ntaub ntawv ntsuab kev loj hlob.
Natural fiber ntau daim txhuam cev ua ke nrog paj rwb, linen, xyoob fiber ntau, thiab lwm yam ntaub ntawv nrog ib tug polymer ua npuas ncauj, sib npaug ib puag ncig tus phooj ywg thiab txhua yam kev ua tau zoo. Cov fibers ntuj muab kev ua pa zoo thiab ua rau daim tawv nqaij - tus phooj ywg zoo, thaum lub elasticity thiab cushioning ntawm cov npuas npuas ua rau nws haum rau cov ntaub ntawv uas xav tau kev nplij siab thiab kev noj qab haus huv, xws li cov khoom me me, siab - cov khoom vaj tsev kawg, thiab eco- textiles. Thaum lub sij hawm ua, lub uniformity ntawm fiber ntau dispersion thiab interfacial bonding zog yuav tsum tau tswj kom lub stability ntawm cov khoom tiav.
Tsis tas li ntawd, qee qhov tshwj xeeb -cov ntaub nplaum lub hom phiaj suav nrog acrylate, roj hmab, lossis silicone-raws li cov khoom hloov kho los txhim kho cov roj ua haujlwm, tiv thaiv tshav kub, lossis kev laus, ua tau raws li qhov xav tau ntawm kev tiv thaiv kev lag luam thiab cov khoom siv sab nraum zoov.
Feem ntau, cov ntaub ntawv tseem ceeb ntawm daim txhuam cev txiav txim siab nws lub cev lub cev, tshuaj tiv thaiv, thiab daim ntawv thov ciam teb. Thaum xaiv cov ntaub ntawv, kev lag luam yuav tsum ua tib zoo xav txog cov kev xav tau ntawm kev ua haujlwm, kev siv ib puag ncig, thiab cov kev xav tau ruaj khov, thiab ua tiav qhov sib npaug ntawm kev ua tau zoo thiab tus nqi los ntawm cov khoom siv kom zoo, yog li nthuav nws qhov chaw ruaj khov hauv ntau qhov chaw.
