Dab tsi yog cov yam ntxwv ntawm cov khoom siv raw rau lub raj mis yas reagent?
Lub raj mis yas reagent yog ib hom ntim ntim uas feem ntau siv rau ntau yam tshuaj reagents.Nws muaj cov yam ntxwv ntawm kev ua siab ntev, tsis muaj tshuaj lom, lub teeb yuag, thiab tsis tawg.Nws cov khoom siv raw yog feem ntau polypropylene.Dab tsi yog cov yam ntxwv ntawm cov khoom siv raw?
Muaj ntau txhiab txhiab hom tshuaj reagents, yog li muaj ntau hom yas reagent fwj.Qhov luaj li cas ntawm lub qhov ncauj lub raj mis tau muab faib ua lub qhov ncauj dav thiab lub raj mis nyias lub qhov ncauj, thiab raws li cov xim, nws tau muab faib ua cov fwj xim av thiab cov fwj zoo tib yam.Polypropylene, raws li nws cov khoom siv tseem ceeb, muaj cov yam ntxwv hauv qab no:
1. Qhov ceev yog me me, tsuas yog 0.89-0.91, uas yog ib qho ntawm cov yas sib zog.
2. Kev ua haujlwm zoo txhua yam, tshwj tsis yog kev cuam tshuam tsis zoo, lwm yam kev ua haujlwm zoo dua li polyethylene, thiab kev tsim cov khoom ua haujlwm zoo.
3. Nrog kev kub siab ua haujlwm, qhov ntsuas kub tsis tu ncua tuaj yeem ncav cuag 110-120 ℃.
4. Nws muaj tshuaj lom neeg ruaj khov zoo, yuav luag tsis nqus dej, thiab tuaj yeem tiv thaiv corrosion ntawm acid, alkali, ntsev tov thiab ntau yam organic solvents hauv qab 80 ℃.
Cov saum toj no yog cov yam ntxwv ntawm cov yas reagent lub raj mis raw cov ntaub ntawv, uas kuj ua rau nws haum rau khaws cia ntawm ntau yam tshuaj reagents.Nws tseem tuaj yeem ua rau hauv lub raj mis xim av los ntawm kev ntxiv cov xim masterbatch los khaws cov tshuaj reagents uas yooj yim rau decompose tom qab raug lub teeb.
