Cross-link yog ib daim ntawv cog lus uas txuas ib lub xov tooj polymer mus rau lwm tus. … Hla txuas ua rau cov molecular loj ntawm ib lub polymer. Cross-linked polymers yog ib qho tseem ceeb vim tias lawv yog cov neeg kho tshuab muaj zog thiab tiv taus cua sov, hnav thiab tawm tsam los ntawm cov kuab tshuaj.
Vim li cas kev sib txuas sib txuas tseem ceeb?
Cross-linking yog txheej txheem ntawm stabilizing collagen los ntawm kev tsim cov kev sib txuas tshiab ntawm cov strands ntawm collagen; Cov txheej txheem no inhibits degradation ntawm collagen los ntawm proteases thiab prolongs nws muaj nyob rau hauv lub qhov txhab [28]. Hom kev sib txuas ntawm txoj kev sib txuas uas tshwm sim ncaj qha cuam tshuam rau kev ua haujlwm ntawm acellular matrices.
Lub hom phiaj tseem ceeb ntawm kev sib txuas hauv cov polymers yog dab tsi?
Polymers rau Cov Khoom Siv Ua Haujlwm Zoo Tshaj Plaws Los ntawm kev sib txuas, cov qauv ntawm cov tshuaj polymer tuaj yeem kho tau. Qhov tshwm sim ntawm cov tes hauj lwm polymer (los yog gels) qhia tus cwj pwm elastic thiab, nyob ntawm seb lub cev, cov khoom siv zoo. Polymer tes hauj lwm muaj peev xwm o los ntawm uptakes dej los yog organic solvents.
Kev sib txuas sib txuas ua rau dab tsi?
Qhov tsim ntawm covalent daim ntawv cog lus uas tuav qee feem ntawm ob peb cov saw hlau ua ke yog hu ua cross-linking. Kev sib txuas ntau yam tshwm sim hauv ib qho kev sib txuas peb-seem sib txuas ntawm cov saw hlau sib txuas, raws li pom hauv daim duab.
Puas hla kev txuas ua kom nws muaj zog?
Crosslinked los yog "ua ke ua ke" chains yuav coj txawv txawv. Lawv yuav tsis ntws ntau npaum li kev ntxhov siab xws li rub lossis cua sov. Lawv yuav tsis o ntau npaum li nyob rau hauv ib qho hnyav li unbound chains, uas txhim kho tshuaj lom neeg / hnyav kuj. Thiab, lawv yuav ua kom muaj zog / tawv dua txheej lossis binder

Vim li cas kev sib txuas sib txuas yog qhov tseem ceeb?
Cov lattice reciprocal plays lub luag haujlwm tseem ceeb hauv kev tshawb fawb feem ntau ntawm cov qauv ntu, tshwj xeeb hauv kev xav ntawm kev sib txawv. Nyob rau hauv neutron thiab X-ray diffraction, vim yog Laue tej yam kev mob, qhov sib txawv ntawm cov khoom xa tuaj thiab cov duab hluav taws xob sib txawv ntawm cov siv lead uayog cov kab lattice vector .
Vim li cas qhov tseem ceeb yog qhov tseem ceeb?
Nws yuav tsum muaj lub zog lub cev thiab lub siab lub ntsws. Qhov tseem ceeb yog qhov tseem ceeb uas tso cai rau koj mus txuas ntxiv thiab ua lub neej zoo. Hauv qhov tseem ceeb, qhov tseem ceeb txhais tau hais tias muaj zog, noj qab nyob zoo, thiab muaj txiaj ntsig zoo.
Vim li cas kev sib txuas lus kev lag luam tseem ceeb?
Kev sib txuas lus zoo yog qhov cuab yeej tseem ceeb rau txhua tus tswv lag luam. … Kev sib txuas lus kuj tseem ceeb hauv kev lag luam. Kev sib txuas lus zoo tuaj yeem pab txhawb kom muaj kev sib raug zoo ntawm kev ua haujlwm zoo ntawm koj thiab koj cov neeg ua haujlwm, uas tuaj yeem txhim kho kev coj ncaj ncees thiab kev ua haujlwm zoo .
Vim li cas kev sib nrig sib tseem ceeb hauv kev sib raug zoo?
Kev sib raug zoo ntawm kev sib raug zoo nrog ua kev cog lus rau ib leeg tias kev sib raug zoo yog ib qho tseem ceeb ib yam li txhua tus neeg… Kev cuam tshuam me me tso cai rau koj tseem yog koj thaum paub tseeb koj tus khub txaus siab thiab zoo siab hauv kev sib raug zoo .
Nyob rau hauv ib qho kev tsis sib haum xeeb pn kev sib tshuam cov kev sib tshuam tam sim no ntawm qhov sib npaug yog?
Nyob rau hauv qhov tsis ncaj ncees PN-kho qhov kev sib tshuam tam sim no ntawm qhov sib npaug yog zero, vim tias sib npaug tab sis cov neeg nqa khoom hla hla kev sib tshuam . Thaum pn kev sib tshuam tsis ncaj ncees qhov kev sib tshuam tam sim no ntawm qhov sib npaug yog?
