Expandable polystyrene, feem ntau hu ua EPS (expandable polystyrene), yog ib hom nthuav dav ua npuas ncauj ua los ntawm polystyrene thiab muaj 5 feem pua mus rau 8 feem pua ntawm cov tshuab tshuab ua los ntawm cov volatility siab thiab qis boiling hydrocarbons, feem ntau pentane. hlaws. Pob tshab hlaws nrog ib tug dawb los yog xim tsis zoo saib muab nws tam sim ntawd.
Ntu 1 Kev Siv Cov Polystyrene Expandable
Vim nws qhov tshwj xeeb thiab ntev thermal rwb thaiv tsev, tshwj xeeb cushioning thiab poob siab tsis kam, muaj hnub nyoog tsis kam, thiab dej tsis kam, expandable polystyrene tau pom dav siv nyob rau hauv ntau yam kev lag luam. Inseparable los ntawm EPS cov nplooj ntawv thiab cov khoom ntim khoom yog cov khoom siv hauv tsev xws li cov tub yees, cov khoom siv hluav taws xob zoo li cov khoom siv ceramic, cov nqaij nruab deg khov, cov zaub khaws cia, txias cia, tsheb ciav hlau, lub tsev hauv nroog, thiab lwm yam.
Tshooj 2 Kev phom sij ntawm Expandable Polystyrene
Nrog lub teeb nyem ntawm {{0}} degree, qhov kub ntawm qhov kub ntawm 260 degree, qhov tawg txwv ntawm 1.5 feem pua rau 7.8 feem pua, thiab tus txheeb ze ntom ntom ntawm 0.63 (dej=1), pentane yog ib tug heev flammable kua. Pentane yog cov nplaim hluav taws kub thiab tawg heev thiab tuaj yeem tawg thaum cua sov, uas ua rau muaj kev pheej hmoo ntawm kev thauj cov polystyrene nthuav dav vim nws qhov tshwj xeeb qis flash point thiab explosive concentration.
Part3 Puas yog tshuaj lom neeg txaus ntshai?
Expandable polystyrene yog ib yam khoom txaus ntshai hauv kuv lub teb chaws thiab raug cais raws li Class I flammable khoom nyob rau hauv cov khoom 1228 ntawm "Cov Khoom Muag ntawm Cov Khoom Siv Hluav Taws Xob" (2015 Edition).
Expandable polystyrene yog categorized raws li 9th qeb ntawm lwm yam khoom txaus ntshai thiab cov khoom, suav nrog cov khoom tsim kev puas tsuaj ib puag ncig, hauv tebchaws United Nations "Cov Lus Pom Zoo rau Kev Thauj Khoom Phem," uas yog cov khoom lag luam txaus ntshai thoob ntiaj teb. Lub pob tsheb thauj mus los yuav tsum siv cov ntim khoom Class III.
Tshooj 4 Kev soj ntsuam cov cai yuav tsum tau ua
1. Cov ntsiab lus ntawm cov khoom tseem ceeb thiab cov khoom xyaw, nrog rau nws cov yam ntxwv ntawm lub cev thiab tshuaj lom neeg thiab ntau hom kev phom sij;
2. Txawm hais tias daim ntawv pov thawj kev nyab xeeb yog txuas nrog (cov khoom lag luam yuav tsum tau nrog daim ntawv pov thawj kev nyab xeeb hauv Suav teb), thiab seb puas muaj cov ntawv tshaj tawm txog kev phom sij ntawm cov khoom ntim khoom (cov khoom lag luam yuav tsum muaj cov ntawv tshaj tawm kev phom sij hauv Suav);
3. Lub thawv hom, ntim cim, ntim ntim, ntim specification, chav tsev qhov hnyav, ntim siv raws li txoj cai, thiab lwm yam rau cov khoom siv phom sij yuav tsum raug kuaj xyuas;
4. Kev soj ntsuam kev ua haujlwm thiab kev siv tshuaj ntsuam xyuas kev ntim khoom ntawm cov khoom lag luam phom sij yuav tsum tau ua raws li "Performance Inspection Result Sheet for Outbound Goods Transport Packaging" thiab "Outbound Dangerous Goods Transport Packaging Use Identification Result Sheet," as well as the cov cai thiab cov qauv ntawm kev tshuaj xyuas thiab kev tswj xyuas cov khoom lag luam txaus ntshai ntim los ntawm hiav txwv, huab cua, txoj kev, thiab kev tsheb nqaj hlau.
