Lub teeb pob zeb Additives | High-Performance Foaming Agents rau Cellular Concrete
Fiber ntau, txoj cai, uas yog cov fiber ntau uas feem ntau siv hauv textiles, tshuaj kho mob, thiab cov khoom yas.
Fiber yog ib yam khoom ntuj los yog hluavtaws filamentous. Nyob rau hauv lub neej niaj hnub, kev siv fiber ntau yog ubiquitous, thiab tseem muaj ntau lub tshuab thev naus laus zis. Lub foob pob hluav taws yuav tsum tau tiv thaiv los ntawm qhov kub thiab txias, tus dej embankment yuav tsum tau tiv thaiv kom txhob tawg, cov cement xav tau los tiv thaiv kev tawg, thiab cov hlab ntsha thiab cov hlab ntsha yuav tsum tau kho. Cov no yog inseparable los ntawm lub cev me me ntawm fiber.
1 Anti-woven kev lag luam
Yooj yim, sov thiab tiv thaiv tshav ntuj yog peb qhov kev xav tau thawj zaug rau khaub ncaws, uas tam sim no tau yooj yim ua tiav. Tom qab seaweed carbon fiber tau ua rau hauv khaub ncaws, nws tuaj yeem ua rau cov tshuaj tiv thaiv thermal ntawm tib neeg molecules kev sib txhuam rau lub sijhawm ntev thaum hnav, thiab txhawb cov ntshav ncig ntawm lub cev, so it can store heat and heat, and the fiber made of ultraviolet radiation can reduce the trouble of our summer umbrella.
2 military aspects
And the bigger role of fiber has long been stuck not only in everyday wear, but also in viscose-based carbon fiber for missiles.
Wearing “heatproof clothing” can withstand tens of thousands of degrees of high temperature; inorganic ceramic fiber has good oxidation resistance, high chemical stability, corrosion resistance and electrical insulation, and is used in aerospace and military fields; Polyimide fiber can be used for high temperature fire protection clothing, racing fireproof clothing, protective clothing for armored forces and flight suits; carbon nanotubes can be used as electromagnetic wave absorbing materials for making invisible materials, electromagnetic shielding materials, electromagnetic radiation pollution protection Materials and “dark room” (absorbent) cov ntaub ntawv.
3 Environmental aspects
As a fully biodegradable plastic, polylactic acid has received more and more attention. Polylactic acid can be made into agricultural film, paper substitute, paper plastic film, packaging film, food container, household garbage bag, pesticide and fertilizer slow-release material, and additives for cosmetics.
4 Medical applications
Chitin fiber is made into medical textiles. It has the functions of antibacterial and deodorizing, anti-inflammatory and anti-itch, moisturizing and anti-drying, and skin care. Yog li ntawd, it can be made into various hemostatic cotton, bandages and gauze. It will naturally degrade after being discarded and will not pollute the environment. Polyacrylamide hydrogels may control drug release; phais sutures ua los ntawm polylactic acid los yog chitosan fibers tau txiav degraded thiab absorbed tom qab qhov txhab kho, thiab cov neeg mob tsis tas yuav raug phais.
5 Kev tsim vaj tsev
Anti-seepage thiab anti-pob txha
fib
r tuaj yeem txhim kho lub zog thiab tiv thaiv kev ua haujlwm ntawm cov pob zeb. Kev siv tshuab fiber ntau ua ke nrog kev siv tshuab ua vaj tse tuaj yeem txhim kho steel fiber ntau thiab hluavtaws fiber ntau uas tuaj yeem txhim kho kev ua tau zoo thiab txhim kho kev tsim vaj tsev zoo. Lub qub yog rau dam, tshav dav hlau thiab kev kub ceev. Txoj kev thiab lwm txoj haujlwm tuaj yeem muab kev tiv thaiv tawg, impermeability, cuam tshuam tsis kam thiab flexural tsis kam. Cov tom kawg tuaj yeem tiv thaiv kev tawg thaum ntxov ntawm cov pob zeb thiab tiv thaiv qhov chaw thaum pib ntawm kev tsim cov khoom siv pob zeb. Hauv cov phiaj xwm loj xws li txoj kev, hydropower, choj, National Grand Theatre, Shanghai Municipal Public Security Bureau hais kom ua qhov chaw ru tsev apron, Shanghai Hongkou football chaw ntau pob, lwm.
6 creatures
Nrog rau kev loj hlob ntawm biotechnology, Qee cov yam ntxwv fiber ntau tuaj yeem ua ke. Cov nqaij zoo li cov fibers tuaj yeem ua rau hauv “cov leeg nqaij” thiab “tib neeg lub cev.” Polyacrylamide yog biocompatible thiab yeej ib txwm yog ib qho kev xaiv zoo rau tib neeg cov ntaub so ntswg. Polyacrylamide hydrogels tuaj yeem cog lus thiab o tsis tu ncua. Cov yam ntxwv no tuaj yeem simulate kev txav ntawm tib neeg cov leeg.
Collagen yog cov protein ntau tshaj plaws hauv tib neeg lub cev. Nws muaj nyob rau hauv tib neeg lub siab, pob qhov muag, cov hlab ntsha, tawv nqaij, pob txha thiab pob txha txoj kev, thiab muab kev txhawb zog rau tib neeg cov ntaub so ntswg. Synthetic nanofibers tsim ib gel zoo li gel ntawm lub pob txha, coj cov pob txha cov zaub mov los tsim cov qauv zoo ib yam li cov pob txha ntuj nyob ib ncig ntawm collagen fibers, kho cov pob txha invisibly.
Kab laug sab txhob lo lo ntxhuav yeej ib txwm siv dag zog los ntawm tib neeg. Ntuj kab laug sab txhob lo lo ntxhuav muaj ib txoj kab uas hla ntawm txog 4 microns, thiab nws lub zog traction yog sib npaug rau 5 lub sij hawm uas steel. Nws kuj muaj cov dej tsis zoo thiab telescopic zoo heev. Yog tias koj tsim cov kab laug sab dag nrog cov yam ntxwv ntawm cov kab laug sab kab laug sab, nws yuav muaj ntau yam kev siv. Nws tuaj yeem siv tsis tau tsuas yog raws li cov khoom siv zoo tshaj plaws rau parachutes thiab lub rooj zaum hauv tsheb, tab sis kuj raws li kev phais suture uas yooj yim absorbed los ntawm lub cev.
