Hloov kho plastics: ua cov khoom siv cov khoom siv thiab tsim kom lub neej tom ntej
Raws li cov khoom siv hluav taws xob tshiab polymer tau los ntawm kev ntxiv cov kev sib ntxiv lossis kev hloov pauv ntawm lub cev lossis hloov cov txheej txheem molecations tau dhau los ua cov khoom tseem ceeb hauv kev lag luam tseem ceeb hauv kev lag luam niaj hnub.
Los ntawm kev ntxiv ib lossis ntau lwm cov tshuaj rau cov tshuaj yas los hloov lawv cov khoom qub thiab ntau yam ntawm kev ua tau zoo, hloov kho kom zoo dua cov ntaub ntawv yas.
1. Dab tsi hloov tau yas?
Hloov kho plastics xa mus rau cov ntaub ntawv tshiab ntawm cov khoom lag luam polymer uas tau los ntawm kev qhia cov qauv molecer ntawm cov qauv sib txuas, lossis tsim cov qauv hauv kob.
Kev hais nruj me ntsis, yuav luag txhua cov ntaub ntawv raw yas muaj tsawg kawg yog qee qhov kev faib ua feem ntawm stabilizers kom tiv thaiv kev tsis sib haum thaum lub sij hawm cia, tsheb thauj mus los, thiab kev ua haujlwm. Cov txheej txheem ntawm kev hloov kho plastics tau ua rau cov khoom siv kom ua tiav kev ua haujlwm zoo dua qub dhau ntawm cov plastics.
Qhov tseem ceeb, cov qauv hloov tshiab yog kev tshawb fawb thiab kos duab hloov cov kev ua kom nruj los ntawm kev ua kom nruj ntawm cov khoom siv hauv kev ua haujlwm tshwj xeeb.
2. Cov yeeb yuj ntiaj teb kev hloov kho
• txhim kho kev hloov kho
Los ntawm kev ntxiv cov fibrous los yog ntawv {- Zoo li fiber, carbon fiber ntau, thiab lub zog ntawm cov khoom siv tau txhim kho.
Cov iav fiber Reints txhawb nylon siv nyob rau hauv cov cuab yeej hluav taws xob yog daim ntawv thov muaj, nrog lub khob fiber ntau dua li 10% mus rau 60%.
• Kev Kho Mob Tawv
Los ntawm kev ntxiv cov tshuaj xws li roj hmab thiab thermoplastic elastomers rau yas, lub zog thiab tej yam muaj zog txhim kho.
Kev siv tshuaj polypropylene (pp) feem ntau siv nyob rau hauv cov khoom siv hauv tsev, thiab kev siv cov tshuab hluav taws xob muaj txiaj ntsig zoo xws li Ethenia Osene Copolers (POE).
• blending thiab alloys
Sib tov ob lossis ntau qhov tsis tiav cov ntaub ntawv yuam kev cov ntaub ntawv kom haum, txhawm rau ua kom tau raws li lub cev, kom tau raws li qhov xav tau rau lub cev, kho tshuab, kho qhov muag, thiab lwm yam khoom.
Alloys zoo ib yam li sib xyaw, tab sis muaj qhov zoo dua ntawm cov khoom siv, ua kom tau yooj yim rau ib qho kev sib xyaw ua ke, xws li pc / abs alloys lossis PS hloov ppo.
• sau kev hloov kho
Txhim kho lub cev thiab cov kws kho tshuab lossis txo tus nqi los ntawm kev ntxiv cov frers kom plastics.
Mineral Pad yog ib txoj kev sib xws, xws li 40% ntxhia txhawb nqa pa6 cov ntaub ntawv, uas tuaj yeem txo cov nqi khoom thaum tswj tau kev ua tau zoo.
• Kev Hloov Kho Mob
Siv cov tub luam ua ke los txo cov roj yas tiv taus cov yas; Ntxiv cov tshuaj tiv thaiv kab mob antioxidants / lub teeb stabilizers los txhim kho huab cua tsis kam ntawm cov ntaub ntawv; Ntxiv cov pigments / dyes kom hloov cov xim ntawm cov khoom; Ntxiv cov roj / sab hauv / sab nraud kom txhim kho kev ua haujlwm.
Siv cov sawv cev nucileating los hloov cov crystallization cov yam ntxwv ntawm semi crystalline thiab txhim kho lawv cov neeg kho tshuab thiab kho qhov muag.
3. Daim ntawv qhia daim ntawv qhia ntawm kev hloov pauv plastics
• Kev Lag Luam Automotive Automotive
Hloov Kho Kom MuajUa si lub luag haujlwm tseem ceeb hauv kev tsim khoom lag luam lag luam. Kev ua tiav PA6 ua tau zoo tshaj rau cov kev siv xws li kev nkag mus, muab lwm cov kub ua haujlwm tsis kam, nruj, thiab tawv.
Cov Ntxhia txhawb kev polypropylene tau siv dav hauv lub tog raj kheej sab hauv thiab kov cov kev ntxuav lub zog sab hauv lub tog raj kheej, hloov qhov kev sib tw tsis txaus, thiab ntau dhau ntawm cov khoom sib xyaw polypropylene.
• Electronic thiab hluav taws xob kev lag luam
Hauv kev muab cov khoom siv hluav taws xob ntawm cov khoom siv hluav taws xob, hloov kho kom zoo nkauj kuj tau pom tias pom tau zoo heev. Toughed PA6 muaj hluav taws xob ua kom zoo nkauj rwb thaiv tsev, uas tuaj yeem tiv thaiv loj thiab huab cua huab cua nyob hauv cov khoom siv hluav taws xob.
Lub hnab yas ua los ntawm PA6 hais tsis yog tsuas yog lub khaub ncaws, tab sis kuj muaj qhov zoo thermal stability, uas tuaj yeem tswj cov duab ruaj khov hauv qhov chaw siab ntev.
• Cov ntaub ntawv kho mob thiab tshwj xeeb
Hloov kho cov plastics kuj tau qhib txoj kev tshiab hauv cov teb kev kho mob. Whisker Silicon Reinforced Yas sib txuas cov siab nruj, tsis kam mus rau Gamma Ray Sauilization, thiab tshuaj lom neeg inertness. Thaum tau thov rau kev phais cov cuab yeej thiab cov cuab yeej siv cov cuab yeej siv, tsis muaj kev pheej hmoo ntawm cov tshuaj tiv thaiv hlau, thiab cov npoo yog yooj yim los ntxuav thiab tshuaj tua kab.
• Kev ruaj khov ntim
Cov thev naus laus zis ntawm kev hloov plastics yog tas li tshiab hauv kev ua teb ntawm kev ntim khoom ruaj khov. Whisker Silicon hloov pauv PE zaj duab xis txhim kho ntau yam kev tawm tsam los ntawm 80% thiab cov pa oxygen cov khoom los ntawm 40% thaum tuav tau pob tshab. Nws yog qhov haum rau cov ntaub qhwv txias txias, anti {{{{{{} zoo li cov khoom siv hluav taws xob, thiab lwm thaj teb, txuas ntxiv cov khoom tiv thaiv qib.
4. Yav Tom Ntej Tiam los ntawm kev hloov pauv plastics
• Kev tiv thaiv ib puag ncig thiab kev txhim kho kom ruaj khov
Tsav los ntawm cov cai thiab ESG (ib puag ncig, kev sib raug zoo, thiab kev tswj hwm), qhov kev thov rau rov ua dua tsiaj (RPET) tau loj hlob sai. Yav tom ntej, nws yog ib qho tsim nyog yuav tsum tau tawg los ntawm cov khoom noj cov khoom siv tshuaj lom neeg thiab ua kom muaj txiaj ntsig los ntawm qhov muaj nuj nqis {2} {2 2} Txuas ntxiv cov khoom lag luam, thiab tsim kom muaj "Green" kev loj hlob loj.
• Kev ua tus kheej thiab ua haujlwm
Hloov kho cov plastics yog txhim kho ntawm tus kheej thiab ua haujlwm. Los ntawm copolymerizing thiab kho, siab - tus nqi muaj txiaj ntsig zoo xws li petg, uas tuaj yeem nkag mus rau cov yeeb yaj kiab loj, ua tiav kev hloov pauv ntawm "rau" tus nqi ".
• Kev hloov kho tshiab thiab ua kom zoo dua
Xws li cov sulfone polymers, pct, tus cwj mem, qhov kawg {}}}}}}}}}}} Cov ntaub ntawv tshwj xeeb thiab cov teeb meem loj. Qhov muaj zog xav tau nyob hauv kev ua lag luam Suav, tshwj xeeb tshaj yog los ntawm kev siv tsheb hluav taws xob thiab kev noj qab haus huv, muab cov chaw tsim khoom loj hloov chaw rau cov lag luam hauv zos.
Tam sim no qhov xwm txheej pom qhov kev loj hlob kev loj hlob thiab muaj peev xwm koom tes nrog kev hloov kho cov saw hlau. Kev lag luam niaj hnub tsis tuaj yeem ua yam tsis muaj kev txhawb nqa ntawm kev hloov pauv plastics. Los ntawm cov khoom siv hluav taws xob rau cov khoom siv hluav taws xob, los ntawm cov khoom siv kho mob rau ib puag ncig kev phooj ywg, hloov kho kom haum plastics yog txuas ntxiv lawv cov ciam teb tas li.
Xaiv kev hloov kho kom haum plastics tsis yog tsuas yog xaiv cov khoom, tab sis kuj hais txog kev xaiv lub neej yav tom ntej.
