Kev xaiv cov khoom ntxiv kom raug yog qhov tseem ceeb hauv kev txhim kho cov khoom siv ntawm cov ntoo-yas sib xyaw (WPCs) thiab kev txhim kho cov khoom ua tiav. Tej zaum teeb meem ntawm kev ntswj, tawg, thiab xim av tshwm sim ntawm qhov chaw ntawm cov khoom, thiab qhov no yog qhov uas cov khoom ntxiv tuaj yeem pab tau. Hauv kab extrusion ntawm WPCs, cov khoom ntxiv yog qhov xav tau kom tau txais qhov ceev extrusion thiab qhov chaw du kom tsis txhob muaj ntug tawg.
Ntawm ntau yam khoom ntxiv uas tau xaiv, cov roj nplua nyeem, cov neeg sawv cev sib txuas, cov tshuaj antioxidants, cov tshuaj stabilizers, thiab cov neeg sawv cev tiv thaiv pwm/tshuaj tua kab mob muaj qhov cuam tshuam loj tshaj plaws rau qhov zoo ntawm cov khoom sib xyaw ntoo-yas. Raws li cov khoom ntxiv tshwj xeeb rau cov khoom sib xyaw ntoo-yas, cov resins matrix sib txawv yuav tsum tsim cov khoom ntxiv tshwj xeeb kom ua tau raws li qhov xav tau ntawm kev ua haujlwm ntawm cov khoom sib xyaw lossis kev ua haujlwm, txawm li cas los xij, muaj ntau yam khoom ntxiv rau cov khoom sib xyaw ntoo-yas, thiab kev xaiv cov khoom ntxiv kom raug yog qhov tseem ceeb rau kev tsim cov khoom sib xyaw ntoo-yas.
Lub Luag Haujlwm ntawm Cov Khoom Ntxiv hauv Cov Ntoo-Yas CompositesHom thiab Cov Txiaj Ntsig
Tus neeg sawv cev sib txuas
Cov neeg sawv cev sib txuas ua ke cov ntoo fibers thiab matrix resin ua ke, txhim kho lub zog flexural thiab rigidity ntawm cov khoom sib xyaw, nrog rau kev txhim kho modulus ntawm kev tiv thaiv kev tawg thiab modulus ntawm elasticity. Cov neeg sawv cev sib txuas kuj txhim kho qhov ruaj khov ntawm cov khoom siv, lub zog cuam tshuam, cov khoom tawg ntawm lub teeb, thiab txo qhov creep, uas yog qhov tseem ceeb heev rau cov khoom xws li balustrades, stair railings, thiab guardrails. Rau cov yas ntoo sib xyaw siv rau hauv cov ntaub ntawv kho kom zoo nkauj, lub luag haujlwm tseem ceeb ntawm tus neeg sawv cev sib txuas yog txo qhov nqus dej ntawm cov khoom siv, uas tuaj yeem zam qhov tshwm sim ntawm kev ntxhov siab tawg los ntawm kev nthuav dav ntawm cov ntoo fibers vim kev nqus dej.
Tshuaj tua kab mob
Rau cov khoom ntoo yas, cov tshuaj antioxidant tseem ceeb yog BHT thiab 1010 ob pawg. Tus nqi BHT qis dua me ntsis, qhov cuam tshuam oxidation tom qab kub zoo, tab sis BHT nws tus kheej tom qab oxidation ua ke, yuav tsim DTNP, cov qauv nws tus kheej yog cov xim daj, ntawm cov khoom ntawm cov xim stains, yog li daim ntawv thov tsis dav. 1010 tsis yog tsuas yog hauv cov khoom ntoo yas xwb tab sis kuj nyob rau hauv tag nrho cov saw hlau kev lag luam polymer muaj ntau yam kev siv thiab tseem yog lub ntiaj teb loj tshaj plaws thiab siv dav tshaj plaws antioxidant.
Cov tshuaj tua kab mob / tshuaj tua kab mob
Tam sim no, cov ntoo yas tiv thaiv pwm thiab cov tshuaj tua kab mob yog ib chav kawm ntawm boron thiab zinc sib xyaw ntsev, cov khoom ntawm pwm thiab cov kab mob lwj ntoo muaj qee qhov kev tiv thaiv, tab sis kuj muaj kev ruaj khov zoo thermal thiab UV stability, kev koom ua ke kuj tuaj yeem txhim kho cov khoom siv hluav taws kub retardant, tab sis cov khoom ntxiv ntau, tus nqi ntxiv siab, thiab cov khoom siv kho tshuab ntawm cov khoom ntoo yas muaj kev cuam tshuam tsis zoo; lwm chav kawm yog cov organic sib xyaw uas muaj arsenic, cov khoom sib xyaw ntawm cov yas yog siv dav. Nrog me ntsis ntawm cov khoom ntxiv, tiv taus pwm, thiab lwm yam ntxwv, tab sis vim tias cov tshuaj muaj arsenic, tsis txog REACH thiab ROSH daim ntawv pov thawj, yog li cov neeg tsim khoom ntoo yas kuj siv tsawg dua.
Cov roj nplua nyeem tuaj yeem txhim kho cov khoom ntawm cov ntoo yas sib xyaw thiab ua kom muaj txiaj ntsig ntau dua. Cov roj nplua nyeem feem ntau siv rau hauv cov ntoo yas sib xyaw yog ethylene bisceramide (EBS), zinc stearate, paraffin wax, oxidized polyethylene, thiab lwm yam. EBS thiab zinc stearate yog siv dav hauv HDPE-raws li cov ntoo yas sib xyaw, tab sis txij li thaum muaj stearate ua rau qhov cuam tshuam ntawm kev sib txuas ntawm maleic anhydride tsis muaj zog, qhov ua tau zoo ntawm ob qho tib si kev sib txuas ntawm cov neeg sawv cev thiab cov roj nplua nyeem txo qis. Yog li ntawd, ntau hom roj nplua nyeem tshiab tseem tab tom tsim.
Kev Ua Haujlwm Zoo Sib Xws Nrog Kev Ruaj Ntseg:Cov Roj Hmab Zoo Rau WPC Uas Zoo Rau Ib puag ncig!
To daws qhov teeb meem ntawm cov roj nplua nyeem ntoo-yas sib xyawskev ua lag luam, SILIKE tau tsim ntau yam ntawmcov roj nplua nyeem tshwj xeeb rau cov ntoo-yas composites (WPCs)
Cov khoom no yog cov polymer silicone tshwj xeeb, tsim tshwj xeeb rau cov ntoo-yas sib xyaw ua ke.
