Tus nqi ntawm dichloromethane siv hauv polyurethane foaming nws txawv nyob ntawm tus qauv thiab qhov ntom. cov
Kev noj tshuaj sib txawv: Cov mis mos ua npuas ncauj nrog qhov ntom ntawm 8kg / m3: Cov nyiaj dichloromethane yog 30 feem. Cov mis mos ua npuas ncauj nrog qhov ntom ntawm 12kg / m3: Tus nqi ntawm dichloromethane yog 15 feem. Cov mis mos ua npuas ncauj nrog qhov ntom ntawm 16kg / m3: Tus nqi ntawm dichloromethane yog 9.3 feem.
Kev siv thiab cuam tshuam:
Dichloromethane feem ntau yog siv los ua lub cev ua npuas ncauj hauv polyurethane foaming los pab txo qhov ntom ntawm cov npuas dej. Nws qhov ntau npaum li cas cuam tshuam rau lub cev lub cev ntawm cov npuas dej, xws li ceev thiab elasticity. Tshwj xeeb:
Qhov ceev: Tus nqi ntawm dichloromethane siv yog inversely proportional rau qhov ntom ntawm cov npuas dej. Qhov ntau nws siv, qhov qis dua qhov ntom ntawm cov npuas dej. Elasticity: Qhov tsim nyog tus nqi ntawm dichloromethane tuaj yeem ua rau cov npuas dej softer thiab elastic dua, tab sis nws yuav txo tau nws lub zog tsim kua muag thiab rov ua dua.
Hloov pauv:
Vim yog vim li cas ib puag ncig, kev siv dichloromethane yuav raug txwv hauv qee qhov chaw. Kev hloov pauv xws li dej kuj tuaj yeem siv rau foaming, tab sis cov nyhuv thiab ntau npaum li cas yuav txawv.
Hauv cov ntsiab lus, tus nqi ntawm dichloromethane hauv polyurethane foaming yuav tsum tau hloov kho raws li cov qauv tshwj xeeb thiab cov khoom ua npuas yuav tsum tau ua kom ntseeg tau tias qhov zoo thiab ua haujlwm ntawm cov khoom kawg.
