Hangzhou Epsole Machinery Co., Ltd. yog ib qho ntawm feem txhim khu kev qha manufacturers thiab lwm tus neeg uas expandable polystyrene eps raw khoom nyob rau hauv Suav teb. Peb sov siab txais tos koj mus yuav cov khoom zoo polystyrene eps raw khoom muag ntawm no los ntawm peb lub hoobkas. Kev pabcuam zoo thiab tus nqi tsim nyog muaj.
Expandable polystyrene eps raw khoom Ntuj
Expandable polystyrene eps raw khoom yog dawb los yog tsis muaj xim pob tshab hlaws nrog ib tug me me particle loj, nrog ib tug txheeb ze ceev ntawm 1.05 mus rau 1.06. Muaj peev xwm ua tau xim arbitrarily, nrog cov tshuaj zoo. Expandable polystyrene uas muaj tsawg-boiling hydrocarbon foaming tus neeg sawv cev tuaj yeem nce nws qhov ntim los ntawm 5 mus rau 50 npaug thaum rhuab mus rau 90 txog 110℃C. thiab lwm yam ntawm cov npuas dej. Kev ua tau zoo ntawm polystyrene ua npuas ncauj yog ze ze rau cov qauv microcellular, thiab muaj feem xyuam rau kev hloov kho thiab cov khoom ntxiv. Yog hais tias cov nplaim hluav taws kub hnyiab tau ntxiv hexabromocyclododecane, cov ua npuas ncauj tau muaj cov nplaim hluav taws kub.
Expandable polystyrene eps raw khoom Manufacturing method
Txoj kev tsim khoom ntawm cov khoom siv polystyrene eps nthuav dav yog tsuas yog ua kom muaj qee yam ntawm cov neeg ua npuas ncauj (tsawg-cov pa roj carbon boiling)) rau hauv cov hlaws cob tau los ntawm txoj kev ncua. Muaj kwv yees li peb hom kev tsim khoom.
Txoj kev impregnation: Txhaj styrene monomer rau hauv dej-raws li polymerization kettle, ntxiv benzoyl peroxide (initiator) thiab hydroxyethyl cellulose (dispersant), thiab ua polymerization ntawm 85-90℃nyob rau hauv stirring. Thaum lub℃ntawm polymerization mus txog ntau tshaj 85%, ib tug foaming tus neeg sawv cev yog ntxiv, thiab cov polymerization yog txuas mus txog rau thaum xaus. Tom qab ntxuav thiab ziab, ib qho khoom nthuav dav polystyrene tau txais. Cov tshuaj tiv thaiv mis yog tib yam li cov hom phiaj dav dav polystyrene, tab sis nws yuav tsum tau ntim nrog cov tshuab tshuab.
Txoj kev impregnationUa ntej, styrene raug tshem tawm thiab polymerized kom tau cov hlaws ntawm ib qho me me, thiab tom qab ntawd muab faib thiab sieved. Tom qab ntawd, ntxiv dej, dispersant, emulsifier thiab foaming tus neeg sawv cev rau cov hlaws resin nrog cov khoom sib xws dua raws li cov txheej txheem ntawm kev tshem tawm polymerization, thiab tom qab ntawd kub thiab impregnate nws nyob rau hauv cov tshuaj tiv thaiv kettle kom tau cov khoom xav tau. Lub zog noj ntawm txoj kev no yog me ntsis loj dua li ntawm ib - kauj ruam txoj kev, tab sis tsis muaj hmoov ua. Cov tshuaj tiv thaiv mis yog tib yam li qhov dav dav ntawm - lub hom phiaj polystyrene, tab sis nws yuav tsum tau ntim nrog cov tshuab tshuab.
Txoj kev ntawm noob polymerizationsiv ib qho me me ntawm polystyrene, polyethylene, polyvinyl chloride los yog polyphenylene ether thiab lwm yam resin hmoov los yog microbeads raws li cov noob kom ncua nyob rau hauv lub polymerization nruab nrab, thiab ces dropwise lub styrene uas muaj cov pib mus rau hauv lub reactor. kom tag nrho. Thaum cov tshuaj tiv thaiv polymerization nkag mus rau theem lig, ntxiv tus neeg sawv cev foaming tuaj yeem tsim cov khoom lag luam nrog qhov loj me me. Expandable polystyrene khoom nrog cov khoom sib txawv tuaj yeem tsim nrog cov noob sib txawv. Yog tias polyethylene siv los ua cov noob, cov khoom tau txais muaj kev cuam tshuam zoo thiab roj tsis kam; Thaum cov polyvinyl chloride siv los ua cov noob, cov khoom npaj nthuav dav polystyrene muaj cov nplaim hluav taws.
