Plaub cov khoom ntawm ntuab
Txhob haus tsis tsuas tau zoo cua dissipation, tab sis kuj muaj zoo kub txuag. Nws cov rwb thaiv tsev sov nyob ntawm nws lub qhov khoob fiber ntau. Muaj ntau ntau me me fibers nyob rau hauv ib lub nyuag fiber ntau, thiab cov pob zeb me me ua los ntawm cov fibers me. Seemingly cov ntaub lo lo ntxhiab, qhov tseeb, ntau tshaj li 38%, yog li ntawd, yog hollow, muaj ntau ntawm huab cua nyob rau hauv lub sib txawv, cov cua tiv thaiv poob ntawm tshav kub, ua ipk muaj lub zoo heev sov so tuav khoom.
Ua ntej, kev nplij siab. Qhov tiag lo lo yaj yog ua los ntawm cov protein ntau, uas yog biocompatible nrog tib neeg lub cev. Dhau li ntawd, nws saum npoo yog tus, thiab nws txoj kev sib txhuam thiab kev txhawb zog coefficient yog qhov qis tshaj plaws ntawm tag nrho cov hom fiber, tsuas yog 7.4%. Yog li ntawd, thaum peb cov tawv nqaij mos thiab mos thiab sib txig tsis sib haum, nws los ntawm nws qhov muag zoo nkauj, raws li txoj kab ntawm lub cev, xav thiab saib xyuas peb txhua nti ntawm daim tawv nqaij yam xyuam xim.
Thib ob, zoo absorbance thiab dehumidification. Kev loj hlob ntawm fibroin fiber ntau (amino - CHNH), hydrophilic pawg xws li amino pawg (NH2), thiab vim nws porosity, yooj yim dej molecular diffusion, yog li nws tau nqus dej noo ntawm huab cua los yog dej, thiab khaws ib hom qe. Hauv qhov kub thiab txias, nws tuaj yeem pab rau daim tawv nqaij khaws qee yam ntawm cov dej noo, tsis txhob qhuav tawv nqaij; Coj nyob rau lub caij ntuj sov, tab sis cov hws uas tib neeg lub cev tau kawm dua thiab sov xa tawm sai dua, ua rau ib tug neeg hnov qab txias thiab clinking. Nws yog qhov cuabyeej uas ua rau cov kabmob tseeb tseeb uas haum rau kev tiv tauj nrog cov tib neeg tej tawv nqaij. Yog li ntawd, cov khaub ncaws txhob lo lo ntxhuav yog ib qho ntawm cov khaub ncaws uas tsim nyog rau lub caij ntuj sov
Thib peb, hnov lub suab, nqus plua plav, tshav kub tsis haum. Cov ntaub qhwv npog muaj porosity, yog li muaj suab nrov zoo tshaj plaws thiab kev sib daj sib deev, zoo li ua rau khaub ncaws hnav, xws li cov ntaub pua chaw, kab xev, ntaub ntsa, ntaub ntsa, thiab lwm yam. kho kom zoo nkauj, tsis yog tuaj yeem ua rau chav tsev huv, tab sis tseem tuaj yeem ua rau lub hoob nyob ntsiag to. Vim hais tias lo lo ntxhuav muaj hygroscopic thiab dehumidifying cov khoom nrog rau cov dej tsis ntub, nqus pa thiab porosity, nws tuaj yeem kho hauv tsev kub thiab cua txias, thiab tuaj yeem nqus cov pa phem, plua plav thiab microbes. Tsis tas li ntawd, cov nyhuv dawb huv muaj cov thermal degeneration me me thiab muaj cua sov - tiv taus. Nws thaum kho kom 100 ℃, tsuas yog 5 ~ 8% hnyav, thaum tseem siv hluav taws xob hluavtaws ntau rau 4 ~ 5 zaug loj dua lo lo ntxhuav. Txhob lo lo ntxhuav ntawm combustion kub ntawm 300 ~ 400 ℃, nplaim hluav taws kub, thiab hluavtaws hluavtaws kub ntawm 200 ~ 2600 c, uas yog flammable, fusible. Raws li, siv cov nyuv fiber ntau li cov khoom siv hauv cov cuab yeej thaij sab hauv, tsis yog tsuas muaj peev xwm muaj lub suab nqus, hmoov av plhaub, kev txuag hluav taws kub, tseem muaj hluav taws kub nyhav dua.
Plaub, uv ua hauj. Lub tryptophan thiab tyrosine nyob rau hauv cov kua protein ntau yuav nqus ultraviolet txoj sab ci, yog li cov kabmob muaj zoo dua anti-ultraviolet muaj nuj nqi. Thiab ultraviolet txoj sab xis yog teeb meem rau tib neeg tej tawv nqaij. Ntawm chav kawm, tom qab absorbing ultraviolet ray, txhob lo lo ntxhuav nws tus kheej tau tsim tshuaj hloov, ua silk ntaub nyob rau hauv lub hnub ci irradiation, ua daj yooj yim.
