Polypropylene (PP) yog cov khoom siv yas ntau, tab sis nws cov kev ua tau zoo tuaj yeem txhim kho nrog kev siv cov khoom ntxiv tshiab. Cov yeeb yaj kiab no ua PP muaj zog dua, ntau dua cov cua sov-resistant, thiab ib puag ncig phooj ywg. Ntawm no yog li cas:
1. Lub zog thiab durability: nanofillers
- Nano-clays: Txhim kho tensile lub zog thiab kev cuam tshuam tsis kam, tiv thaiv kev tawg.
- Cov Nanotubes (CNTs): Txhawb lub zog, txhav txhav, thiab cov teeb meem.
2. Thaum tshav kub tiv thaiv: cua sov stabilizers
- Orgototin-bortricbizers: Txhim kho cov kev kub kub kub, siv hauv kev lag luam hluav taws xob thiab hluav taws xob.
- Cov tshuaj calcium raws li stabilizers: Eco-fromon Lwm txoj kev muab cov kev tiv thaiv hluav taws xob zoo sib xws.
3. UV kev tiv thaiv: UV stabilizers
- Hindered Amine Teeb Stabilizers (Hals): Tiv thaiv pp los ntawm kev ua brittle thiab discolored hauv UV kis tau.
- UV nqus: Nqus UV hluav taws xob, nthuav tawm lub neej ntawm PP hauv chaw ib sab.
4. Hobinal: Antioxidants
- Phenolic Antioxidants: Cov tshuaj oxidation qeeb, muaj lub zog thiab xim.
- Phosphite-raws antioxidants: Qhov zoo tagnrho rau cov ntawv thov kom siab kub, tiv thaiv kev ua kom tsis pom zoo.
5. Kev tsim khoom lag luam: Ua AIDS
- Nco ntsoov cov neeg sawv cev & AntiBlock tus neeg sawv cev: Txhim kho cov dej ntws tawm txaus ntshai, txo cov tsis taus.
- Tej roj qeeb: Txhim kho kev ua haujlwm tau zoo, txo lub caij nyoog.
6. Kev Ua Neeg Nyob: eco-frienditives
- Biodegradable ntxiv: Ua kom nrawm dua PP qhov kev cuam tshuam hauv av pov tseg, txo cov khib nyiab yas.
- Rov qab ua dua ntxiv: Teeb tsa ua ke cov neeg siv khoom noj ntxiv PP, txhawb nqa cov kev lag luam muaj txiaj ntsig.
Xaus:
Tsim kev ntxiv ntxiv yog kev hloov pauv PP, txhim kho nws cov kev ua tau zoo thiab kev ruaj khov. Los ntawm txhim kho lub zog kom zoo dua kub tsis kam thiab cov kev daws teeb meem no yog paving txoj hauv kev rau kev ua haujlwm siab pp hauv kev ntim thiab dhau mus.
