Seb nws lub tsheb thauj khoom txoj kev, cov khauj khaum, cov khoom lag luam uas pom tau zoo rau hom duab, thiab cov neeg siv khoom siv ntawm cov khoom lawv tus kheej. Txawm li cas los xij, cov khoom no tsis ntev tas li yog raug rau kev sib tw nruj hauv chaw ua si tuaj yeem ua rau muaj cov khoom siv fadiviaolet yuav ua rau cov khoom siv fad Rov ua qhov kub thiab txias thiab cov av noo hloov pauv yuav ua rau tawg thiab deformation; thiab tshuaj lom neeg nyob hauv huab cua thiab dej nag kuj tseem tuaj yeem ua rau kev xeb thiab staining.
Txhawm rau kom ntseeg tau tias cov khoom lag luam uas tau txais lawv cov qub txawm hais tias muaj cua, thiab nag, huab cua siab- Cov ntaub ntawv tsis kam yog tus yuam sij. Cov ntaub ntawv tshwj xeeb tsim nyog muaj ntau yam khoom siv huab cua, txuas ntxiv txo cov nqi thiab cov nqi hloov kho tag nrho cov nqi thiab cov hom lag luam kev sib tw ua lag luam. Xaiv cov huab cua zoo - Cov ntaub ntawv resistant yog zoo li equipping cov khoom uas yog ob qho tib si ua kom zoo nkauj thiab ruaj khov.
Kab lus no yuav ua tsom rau tam sim no maj mam nrhiav {{} {} {qhov kev ntsuas tseem ceeb, thiab cov ntsiab lus technology. Ua ke nrog kev ua lag luam kev tshuaj xyuas thiab cov ntawv thov kev vam meej thoob plaws kev lag luam, lub hom phiaj yog muab cov huab cua zoo {}}}} ionistant cov ntaub ntawv hauv kev tsim cov khoom lag luam sab nraud.
Heev huab cua -} iveistant pp khoom siv: kev lag luam thiab kev xaiv siv rau huab cua tsis kam.
Cov hauv paus ntsiab lus
Polypropylene (PP) yog siv dav siv dav dav - lub hom phiaj yas. Cov roj carbon abon atom qauv hauv nws cov molecular charuct ua rau cov khoom siv rau ultraviolet, uas ua rau muaj nkig, thiab kev poob qis ntawm cov tshuab tshuab. Yog li ntawd, unmodified pp cov ntaub ntawv feem ntau tsis tsim nyog rau kev siv uas muaj kev cuam tshuam ntev-}} sij hawm sab nraum zoov kis tau.
Tus yuam sij rau kev ua tiav cov huab cua siab hauv PP lus dag hauv kev cuam tshuam lossis kev ncua cov txheej txheem kev pab cuam uas ultraviolivizers (UVA), tabkaum amine lub teeb cigilizers, thiab antioxidants. Muaj qee kis, Copolymerization Kev hloov kho yuav ua haujlwm los qhia cov txheej txheem sib txawv ntau ruaj khov, lossis xws li cov nanopartically txhim kho cov huab cua huab cua.
Cov yam ntxwv
Piv rau tus qauv pp, siab - huab cua nrawm dua txhim kho cov kev ua kom nrawm dua ntawm cov kws kho mob tshuab hluav taws xob (thaum tswj hwm cov xim hloov pauv me me (ΔE). Piv txwv li, tshawb fawb los ntawm Xinjiang University qhia tias qhov sib ntxiv ntawm kev tiv thaiv kev laus ntxiv txhim kho PP's tawg tom qab 12 lub hlis ntawm kev kis lub hnub hauv Turpan.
PP Ua hauv kev muaj cov tshuaj zoo heev thiab ruaj khov rau feem ntau acid, alkali, thiab cov ntsev kua. Siab - huab cua {}}}}}}}}}} awnically thaum ua ke kom ua ke ntawm rigidity, kev tiv thaiv nruj, thiab kev cuam tshuam los ntawm kev hloov kho formulations. Piv rau ntau lub tshuab tsim txua, siab {} huab cua {}}} coated cov hlau lossis ntau dua cov plastics nyob rau hauv ntau cov ntawv thov sab nraum zoov. PP lub ntom ntom (kwv yees li 0.9-0.91 g / cm³ilitates tsim cov khoom lag luam, tshwj xeeb hauv kev lag luam thiab cov khoom hauv tsev.
Cov Ntaub Ntawv Thov Raug Zoo
Cov huab cua kub {{}} iveistant pp yog dav siv nyob rau hauv tus nqi ntawm cov huab cua, thiab cua sov} {}} cov huab cua tsis pub dhau lub cav sib ceg. Cov khoom siv no yog kom muaj kev sib tw tas mus li ntawm lub hnub, nag thiab cuam tshuam los ntawm cov xuab zeb thiab gravel xyoo- round. Cov huab cua zoo {{}} хillant pp tuaj yeem hloov cov nqi ntau lawm, thiab ua kom yooj yim cov nqi tsim khoom, thiab ua kom yooj yim rau cov nqi ntau lawm, thiab ua kom yooj yim rau cov nqi tsim khoom, thiab ua kom yooj yim rau cov nqi tsim khoom, thiab ua kom yooj yim rau cov nqi tsim khoom, thiab ua kom yooj yim rau cov nqi tsim khoom, thiab ua kom tau cov nqi tsim khoom siv tau yooj yim
