Cov khoom siv PPH yog qhov hnyav molecular, tsis tshua muaj melting point homopolymer polypropylene, uas tau hloov kho nrog cov qauv zoo nkauj thiab mos Beta siv lead ua, nws tsis tsuas yog muaj tshuaj lom neeg zoo heev, kub tsis kam, thiab nkag siab zoo, tab sis kuj muaj kev cuam tshuam zoo heev. ntawm qhov kub thiab txias.
PPH cov ntawv yog ib hom tshiab ntawm cov khoom siv ib puag ncig zoo nrog ntau yam khoom tshwj xeeb thiab cov yam ntxwv.
1. Muaj zog thiab kav ntev
PPH cov ntawv muaj lub zog siab thiab ua haujlwm ntev, thiab tuaj yeem tiv taus lub zog siab thiab cuam tshuam. Qhov no ua rau nws haum rau ntau qhov chaw, xws li architecture, rooj tog tsim, tsheb tsim, thiab lwm yam.
2. Kev ua haujlwm ib puag ncig
PPH nplooj ntawv yog ua los ntawm biodegradable cov ntaub ntawv uas tsis tso tawm cov teeb meem, yog ib puag ncig tus phooj ywg, thiab ua tau raws li ib puag ncig.
3. Yooj yim rau txheej txheem thiab zoo li
PPH nplooj ntawv yog ib qho yooj yim los txiav, xyaum, thiab txhuam, thiab tuaj yeem hloov kho rau ntau yam duab thiab ntau thiab tsawg.
4. Xim thiab kev ntxhib los mos sib txawv
PPH nplooj ntawv muaj ntau yam xim thiab textures xaiv los ntawm, thiab tuaj yeem kho raws li qhov sib txawv ntawm daim ntawv thov thiab cov qauv tsim.
5. Kev ua haujlwm ntawm hluav taws kub
PPH cov nplooj ntawv muaj kev tiv thaiv hluav taws zoo heev thiab tuaj yeem ua kom muaj kev ruaj ntseg hauv qhov kub thiab txias yam tsis muaj cov khoom tsim teeb meem.
6. Corrosion kuj ua tau zoo
PPH cov nplooj ntawv muaj kev tiv thaiv corrosion zoo heev thiab tuaj yeem tswj kev ruaj ntseg hauv ntau qhov chaw, ua rau lawv haum rau thaj chaw xws li marine, tshuaj, thiab kev tsim kho.
Daim ntawv thov Scope ntawm PPH ntawv:
1. Cov kav dej kub thiab dej txias hauv tsev;
2. Muaj dej thiab tshuaj lom neeg kev thauj mus los thiab tawm;
3. Cov dej ntshiab thiab cov kav dej haus;
4. Dej haus thiab tshuaj tsim khoom thiab kev thauj mus los;
5. Cov yeeb nkab cua compressed;
6. Lwm cov kav dej thiab ua liaj ua teb.
Hauv cov ntsiab lus, PPH cov ntawv yog ib hom tshiab ntawm cov khoom siv nrog lub zog siab, kev tiv thaiv ib puag ncig, kev ua haujlwm yooj yim, ntau yam xim thiab textures, hluav taws kub thiab corrosion kuj. Cov yam ntxwv no ua rau nws muaj kev thov dav dav hauv ntau qhov chaw.
