Taw qhia rau EPS Raug
● Cov lus txhais ntawm nthuav dav polystyrene (EPS)
Txhab polystyrene (eps) yog qhov sib zog ntawm tes yas muab los ntawm cov hlaws hlaws los ntawm cov nqaij hlaws ntawm polystyrene. Cov hlaws dai tau nthuav dav thiab moulded rau hauv ntau yam duab thiab ntau thiab tsawg los tsim lub teeb yuag, tseem muaj cov khoom siv muaj zog. EPS feem ntau siv rau hauv ntim, tsim kho, thiab raws li cov khoom siv Cushioning hauv kev thauj mus los.
● Qhov tseem ceeb thiab
Cov ntawv thov ntawm EPS hauv ntau yam lag luam
EPS ua kev zoo siab rau nws cov versatility thiab yog cov khoom uas nyiam tshaj plaws hauv ntau daim ntawv thov. Hauv kev tsim kho kev tsim kho, EPS ua haujlwm ua lub zog - cov khoom siv rwb rwb. Nws lub zog lub zog ua rau nws zoo tagnrho rau kev ntim cov khoom tsis txaus, thiab nws lub teeb yuag sib tw coj txoj kev zoo. EPS kuj tseem siv nyob rau hauv cov khoom noj ntim khoom, ua qauv ua qauv, thiab txawm tias nyob hauv cov khoom siv kho mob.
Cov Khoom Siv Raw Rau Eps Ntau Lawm
Cov Khoom Siv Tseem Ceeb: STYRENE thiab Pentane
Thawj cov ntaub ntawv raw hauv EPS ntau lawm yog styrene thiab pentane. Styrene, ib qho los ntawm byproduct ntawm roj av thiab cov nkev tuag, ua cov qauv xov ntawm lub ntsej muag. Pentane, ib lub hydrocarbon compound, ua raws li tus neeg sawv cev ntawm cov neeg sawv cev uas pab nthuav cov ris tsho polystyrene.
● QHOV CHAW THIAB COV KHOOM NTAWM COV NTAUB NTAWV
Styrene thiab pentane yog tau los ntawm cov roj crude thiab cov nkev los ntawm cov txheej txheem tshuaj lom neeg. Styrene yog cov kua roj ua kua nrog cov ntxhiab tsw qab, thaum lub sij hawm pentane yog cov kua hluav taws xob ntau. Ob cov ntaub ntawv yog qhov tseem ceeb hauv kev tsim cov khoom tshwj xeeb ntawm EPS, xws li nws cov thermal bermalivity thiab kev muaj peev xwm siab.
EPS Cov Khoom Siv Tsim Kho Cov Txheej Txheem Txheej txheem cej luam
● Ib qho - theem vs. ob - Kauj Ruam Cov Txheej Txheem
EPS tuaj yeem tsim kho siv rau ib qho - kauj ruam lossis ob txheej txheem - theem. Ib qho - cov txheej txheem kauj ruam cuam tshuam nrog ncaj qha thermal thermal extrusion ntawm cov khoom siv, feem ntau yog siv rau cov ntawv thiab zaj duab xis. Ob kauj ruam - kauj ruam txheej txheem, ntau dua rau cov khoom lag luam moulded, koom ua ntej - nthuav cov hlaws dai thiab tom qab ntawd moulding lawv mus rau hauv lub ntsej muag xav tau.
● Ua ntej ua ntej - Kev nthuav dav, Maturing / Ruaj Khetilization, thiab Moulding theem
Ob tug txheej txheem tshiab muaj ntawm peb theem loj:
1. Ua ntej - Kev nthuav dav: Polystyrene hlaws dai yog nthuav tawm cov chav kub ntawm qhov kub, ua rau cov pentane mus evaporate thiab nthuav cov hlaws dai.
2. Maturing / Stabilization: Qhov nthuav tawm cov hlaws dai tau khaws cia kom lawv ncav cuag qhov sib npaug.
3. Moulding: Cov hlaws pleev hluav taws xob ruaj khov yog pwm rau hauv cov block lossis cov duab kev cai siv chav.
Cov theem no yog qhov tseem ceeb heev los ua kom muaj qhov ntom ntom ntom ntom thiab cov neeg kho tshuab ntawm cov khoom siv eps kawg.
Lub luag haujlwm ntawm tshuab cov neeg sawv cev hauv EPS ntau lawm
● Cov ntsiab lus txhais thiab hom kev ua kom cov neeg sawv cev
Tshuab cov neeg sawv cev yog cov tshuaj uas tsim cov qauv ntawm tes los ntawm cov txheej txheem ua npuas. Lawv tuaj yeem yog catalized tshuab cov tshuaj tiv thaiv lub cev thiab cov tshuaj tiv thaiv tshuaj lom neeg. Nyob rau hauv cov ntsiab lus ntawm EPS, pentane yog feem ntau siv cov neeg sawv cev.
● Pentane ua thawj tus neeg sawv cev
Pentane, ib qho kev sib txuas hauv hydrocarbon, yog siv los nthuav polystyrene hlaws los ntawm EPS tsim khoom. Nws yog qhov zoo tshaj vim tias nws tsis muaj chlorine, ua rau nws tsis muaj kev phom sij rau ozone txheej piv rau lwm cov neeg sawv cev xws li CFCS. Txawm li cas los xij, lub pentane yuav pab txhawb rau cov txiv kab ntxwv organic (vocs) cov pa hluav taws xob, albeit hauv cov khoom tsawg.
Lub foaming txheej txheem hauv EPS ntau lawm
● Theem: Tsim Cell, thiab kev sib deev thiab ua kom nruj
Cov txheej txheem ua npuas dej hauv EPS ntau lawm tuaj yeem faib ua peb theem tseem ceeb:
1. Cell Tsim: Ib lub tshuab sawv cev yog ntxiv rau molten polymer, tsim cov polymer / roj daws. Raws li cov roj khiav tawm, nws tsim lub nuclei cell.
2. Cell Kev Loj Hlob: Lub siab sab hauv lub hlwb txo qis, ua rau lub hlwb los nthuav thiab sib koom ua ke.
3. Kev ruaj khov ntawm tes: lub tshuab ua npuas dej ruaj khov los ntawm kev txias lossis ntxiv cov surfactants los tiv thaiv kev sib tsoo ntawm cov qauv ntawm tes.
● Cov txiaj ntsig thiab cov kev sib tw ua npuas ncauj
Lub foaming txheej txheem muab are nws tus cwj pwm lub teeb yuag thiab cov khoom insulating. Txawm li cas los xij, ua tiav ib qho kev hloov pauv ntawm tes ntawm cov qauv ntawm tes thiab cov tsis taus tsawg dua tuaj yeem nyuaj. Kev nrhav hauv cov foaming thev naus laus zis tsom mus txhim kho kev ruaj khov thiab ua haujlwm ntawm EPS cov khoom.
Kev cuam tshuam ib puag ncig thiab kev ruaj khov ntawm EPS
● Pentane qhov cuam tshuam rau Ozone Txheej thiab Voc emissions
Pentane, txawm hais tias tsawg dua kev phom sij ntau dua li CFCS, puas pab txhawb rau VOC pa. Cov kuab zis no yog cov kev tswj kom nruj kom txo qis kev cuam tshuam ib puag ncig. EPS kev lag luam yog nquag tshawb nrhiav txoj hauv kev los txo cov kev siv pentane siv thiab txhim kho cov txheej txheem kev ua kom rov zoo dua los ntawm kev txhawj xeeb ib puag ncig.
