1. Daim ntawv Lub longitudinal kev coj ntawm lub polypropylene yog tus thiab lub Cross seem yog puag ncig.
2. Qhov ceev tshaj plaws Polypropylene qhov loj tshaj yog qhov nws lub cev nyhav. Nws ceev ntawm tsuas yog 0.91g / cm3 yog lub lightest ntawm feem ntau cov tshuaj fibers, yog li tib lub luj ntawm polypropylene yuav tau nrog ntau dua li lwm fibers.
3. Lub zog muaj zog polypropylene muaj lub zog siab, loj elongation, pib thaum pib modulus thiab zoo heev elasticity. Yog li ntawd, polypropylene tau zoo coj kuj. Tsis tas li ntawd, lub zog ntub ntawm polypropylene yog yeej sib npaug los qhuav lub zog, yog li nws yog ib qho khoom zoo rau kev nuv ntses nets thiab cables.
4. Hygroscopicity thiab Dyeability
Polypropylene muaj hygroscopicity me ntsis thiab yuav luag tsis yog-hygroscopic. Cov dej ntws rov qab rau hauv lub cev tsis zoo nyob rau hauv cov xwm txheej atmospheric yog nyob ze rau xoom. Txawm li cas los xij, nws muaj kev cuam tshuam txog kev hloov pauv dej ntawm lub capillary nyob rau hauv ntaub, tab sis tsis nws tus kheej nqus txhua qhov kev nqus. Lub dyeability ntawm polypropylene yog pluag, thiab chromatogram tsis tiav, tab sis cov qauv ntawm cov xim thawj cov khoom siv tau los ua rau cov deficiency.
5. Acid thiab alkali tsis kam
Polypropylene muaj tshuaj lom neeg kuj zoo. Ntxiv nrog rau cov nitric acid thiab concentrated caustic soda, polypropylene tau zoo tsis kam mus rau acid thiab alkali, ces nws yog tsim rau siv li cov ntaub ntawv lim thiab ntim khoom.
6. Lub teeb ua haujlwm, lwm yam zoo li Polypropylene muaj lub teeb tsis kam, tsis thermal stability, yooj yim laus, thiab tsis tiv taus ironing. Txawm li cas los, nws muaj peev xwm los txhim kho kev tiv thaiv kev laus los ntawm kev ntxiv rau tus neeg laus los tiv thaiv kev laus thaum lub sij hawm ntawm kev sib tw. Tsis tas li ntawd, polypropylene muaj hluav taws xob zoo hluav taws xob, tab sis nws yog ib qho yooj yim los tsim hluav taws xob hluav taws xob thaum lub sij hawm ua.
