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 cov cua kub hloov pauv tuaj yeem ncav cuag ntau dua 250 degrees.
3. corrosion kuj.Nylon yog heev resistant rau alkali thiab feem ntau ntsev kua, kuj resistant rau qaug zog acids, lub cev muaj zog roj, roj av, aromatic compounds thiab cov kuab tshuaj, inert mus rau aromatic tebchaw, tab sis tsis resistant rau muaj zog 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 qho chaw qhuav, nws tuaj yeem siv los ua cov khoom siv hluav taws xob ntau zaus, thiab nws tseem muaj hluav taws xob rwb thaiv tsev zoo txawm tias nyob rau hauv qhov chaw muaj av noo.
