PMI Nplaim Retardant Properties ntawm Carbon Fiber Sandwich Ua Npuas Ncauj

Views:136 Author: Dej Hiav Txwv Tshaj Tawm Sijhawm: 2022-02-13 keeb kwm:

Cov khoom siv tseem ceeb ua npuas ncauj yas siv ob lub rooj tsavxwm thiab tom qab ntawd muab cov npuas npuas hauv nruab nrab. Lub hom phiaj ntawm qhov no yog ua kom tau raws li thermal rwb thaiv tsev ntawm cov tsev thiab cov nyhuv ntawm lub suab rwb thaiv tsev. Nws tsis yooj yim rau txheej txheem, thiab cov khoom siv hauv nruab nrab feem ntau yog ua los ntawm cov npuas dej thiab tom qab ntawd ua tiav rau hauv cov sandwich panels. Cov ntaub ntawv tseem ceeb no ua rau muaj kev ua si tag nrho rau cov khoom tshwj xeeb ntawm cov khoom siv pob zeb wool, uas yog fireproof, thiab kuj muaj cov thermal rwb thaiv tsev zoo, thiab muaj cov yam ntxwv tshwj xeeb ntawm rwb thaiv tsev kub, suab nrov thiab suab rwb thaiv tsev.

Cov khoom siv tseem ceeb no yog ua los ntawm cov xim hlau pob zeb wool sandwich vaj huam sib luag, uas yog ua tiav los ntawm pob zeb ntaub plaub thiab steel phaj, kom lub rooj tsavxwm tuaj yeem ua tau raws li cov kev cai ntawm lub tsev thermal rwb thaiv tsev, suab rwb thaiv tsev, tiv thaiv hluav taws, thiab cov khoom siv no Kev nyab xeeb ntawm kev siv kuj yog qhov siab, yog li cov hom phiaj ntawm kev ua haujlwm siab, kev ua haujlwm siab, kev ntseeg siab thiab kev nyab xeeb tuaj yeem ua tiav, yog li cov khoom siv no kuj siv los ntawm txhua tus. Lub polystyrene core ua npuas ncauj yog ua los ntawm cov xim hlau phaj raws li qhov chaw, thiab kaw-cell nws tus kheej-extinguishing polystyrene ua npuas ncauj ua lub hauv paus.

Ib hom tshiab ntawm high-efficiency composite tsev cov khoom ua los ntawm high-strength adhesives tom qab xim hlau phaj yog nias los ntawm ib tug tsis siv neeg nruam txoj kev tshuab. Nws muaj cov yam ntxwv ntawm thermal rwb thaiv tsev, waterproof ib zaug ua tiav, kev tsim kho sai, ruaj khov, zoo nkauj thiab lwm yam. 

Cov khoom siv tseem ceeb ua npuas ncauj yas muaj qhov zoo ntawm lub teeb yuag, 1/20 ~ 1/30 ntawm qhov hnyav ntawm lub ru tsev pob zeb, thermal rwb thaiv tsev, thermal conductivity nqi ntawm 0.034W / mk, kev tsim kho ceev ceev, tsis ntub dej, tsis muaj kev kho kom zoo nkauj theem nrab. , thiab lub sijhawm tsim kho tuaj yeem ua rau luv luv los ntawm ntau dua 40%, cov xim yog ci, tsis tas yuav tsum tau kho kom zoo nkauj, thiab lub sijhawm txij nkawm ntawm cov xim galvanized steel phaj yog 15-30 xyoo.

Nyob rau hauv xyoo tas los no, ntau qhov hluav taws kub sib tsoo tau tshwm sim ib qho zuj zus, uas ua rau muaj kev phom sij loj rau kev nyab xeeb ntawm tib neeg lub neej thiab cov khoom ntiag tug thiab kev nyab xeeb rau pej xeem, feem ntau vim tias cov khoom nws tus kheej yog hluav taws kub thiab yuav tsim cov pa phem thaum hlawv. Carbon fiber ntau sandwich ua npuas ncauj yog lub teeb yuag, fireproof, thermal rwb thaiv tsev cov khoom yas nrog kev ua tau zoo, uas yog nplaim taws, tsis muaj pa taws, tsis muaj tshuaj lom thiab thermal stability. Nrog rau kev tsim cov thev naus laus zis, cov khoom siv sandwich yog siv ntau dua rau cov khoom sib xyaw.

Cov carbon fiber sandwich ua npuas ncauj yog tsim los ntawm cov txheej txheem tom qab molding, siv ob lub ntsiab lus polyisocyanate emulsion hom nplaum, uas yog manually dov thiab sizing, thiab sizing tus nqi yog 180 ~ 200g / m2. Laminate nyob rau hauv lem, muab tso rau ntawm ib tug txias xovxwm rau 45 feeb, thiab cia rau 24 teev tom qab decompression, thiab ces txiav lawv raws li cov neeg siv khoom xav tau.

Qhov nyuaj ntawm combustion yog cuam tshuam nrog cov pa index ntawm cov khoom. Cov pa ntsuas pa yog hais txog cov pa oxygen xav tau rau cov nplaim hluav taws kub ntawm cov khoom hauv cov pa oxygen-nitrogen sib xyaw hauv cov xwm txheej tshwj xeeb. Qhov siab dua qhov ntsuas qhov ntsuas pa, qhov siab dua cov pa oxygen xav tau los tswj kev sib txuas, uas txhais tau hais tias nws nyuaj rau hlawv. Cov pa ntsuas pa ntawm carbon fiber sandwich ua npuas ncauj yuav siab li 46.8%, cov pa luam yeeb ntom ntom yog 2.5%, cov pa luam yeeb ntom ntom yog 1.83, thiab cov pa luam yeeb tawm tsawg heev. 

Thaum lub sij hawm combustion xeem, lub cev tseem ceeb tsis yaj los yog drips, tab sis nws shrink me ntsis, thiab cov nplaim nplaim tiv tauj ib feem yog carbonized. Cov pa ntsuas pa ntawm cov pa roj carbon fiber ntau yog 42.5%, uas tau mus txog qib B1 ntawm cov nplaim hluav taws, thiab cov pa luam yeeb ntom ntom yog 20.44%. Deb tsawg dua cov pa luam yeeb ntom nti ntawm cov nplaim hluavtaws sib xws tsis yog-nplaim retardant fiberboards los ntawm 50% mus rau 80%. Lub vaj huam sib luag carbon fiber ntau tau npaj los ntawm kev siv ob cov ntaub ntawv no nrog cov nplaim hluav taws zoo heev tuaj yeem tiv thaiv kom tsis txhob muaj hluav taws sib kis thaum muaj hluav taws kub.

Cov nplaim hluav taws-retardant carbon fiber board cladding tsis tsuas yog kov yeej qhov teeb meem ntawm huab cua yooj yim ntawm pp sandwich panels, tab sis kuj muaj qhov zoo ntawm cov nplaim hluav taws kub, tsis muaj pa taws, lub teeb yuag thiab lub zog siab, buffering thiab lub zog nqus. Cov pa roj carbon fiber ntau sandwich ua npuas ncauj yog nplaim hluav taws thiab muaj cov khoom siv zoo heev. Nws tuaj yeem siv rau hauv kev tsim tsheb, khoom siv kho mob thiab lwm yam haujlwm. Nws tuaj yeem tsis tsuas yog txo cov khoom zoo thiab txhim kho cov kabmob muaj peev xwm, tab sis kuj txo qhov tshwm sim ntawm hluav taws vim nws cov nplaim hluav taws zoo heev, ua kom lub teb chaws cov cuab yeej thiab tib neeg lub neej. Muaj kev nyab xeeb, nrog cov txiaj ntsig zoo nyiaj txiag thiab kev sib raug zoo.
