Vim li cas peb xaiv nylon ntaub?
Nylon yog thawj cov khoom siv hluavtaws uas tau tshwm sim hauv ntiaj teb. Nws cov synthesis yog ib qho tseem ceeb hauv kev lag luam hluavtaws fiber ntau thiab tseem ceeb heev hauv kev ua cov tshuaj polymer.
Dab tsi yog qhov zoo ntawm nylon ntaub?
1. Hnav tsis kam. Kev hnav tsis kam ntawm nylon yog siab dua li ntawm lwm cov fibers, 10 npaug siab dua paj rwb thiab 20 npaug siab dua ntaub plaub. Ntxiv qee cov polyamide fibers rau cov ntaub sib xyaw tuaj yeem txhim kho nws cov hnav tsis kam; thaum ncav cuag 3 Thaum -6%, qhov elastic rov qab tuaj yeem ncav cuag 100%; nws tuaj yeem tiv taus ntau txhiab zaus ntawm kev khoov yam tsis muaj kev tawg.
2. kub tsis kam. Xws li nylon 46, thiab lwm yam., siab crystalline nylon muaj lub siab kub distortion kub thiab tuaj yeem siv tau ntev ntawm 150 degrees. Tom qab PA66 tau ntxiv dag zog nrog cov iav fibers, nws qhov kub thiab txias tuaj yeem ncav cuag ntau dua 250 degrees.
3. corrosion kuj. Nylon tiv taus alkali thiab cov kua ntsev feem ntau, kuj tiv taus cov acids tsis muaj zog, cov roj cav, roj av, cov tshuaj tsw qab thiab cov kuab tshuaj, inert rau cov tshuaj tsw qab, tab sis tsis tiv taus cov acids thiab oxidants. Nws tuaj yeem tiv taus qhov yaig ntawm cov roj av, roj, roj, cawv, qaug zog alkali, thiab lwm yam thiab muaj peev xwm tiv thaiv kev laus.
4.Rwb thaiv tsev. Nylon muaj lub siab ntim tsis kam thiab siab tawg voltage. Nyob rau hauv ib puag ncig qhuav, nws tuaj yeem siv los ua cov khoom siv hluav taws xob ntau zaus, thiab nws tseem muaj cov hluav taws xob rwb thaiv tsev zoo txawm tias nyob rau hauv qhov chaw siab.
