Qee qhov kev ntsuam xyuas tseem ceeb rau yas - feem 1

1.Ash test

cov khoom siv uas yuav tsum tau kuaj: Muffle lub qhov cub / tshauv cov ntawv sib tw

Tshauv: Thaum muaj kev kub ntxhov, lub polymer muaj kev hloov ntawm lub cev thiab kev hloov tshuaj. Thaum kawg, cov khoom xyaw organic thiab cov khoom siv hauv nruab deg (tsuas yog cov inorganic salts thiab oxides) nyob twj ywm, thiab cov residues no hu ua tshauv. Feem ntau cov khoom hloov sab hauv, tshauv yog silica, calcium carbonate, talc, iav, titanium dioxide thiab qee qhov lwm cov inorganic cov zaub mov.

Txoj kev ntsuas: Txoj kev ua kom lub cev (combustion ntawm cov organic teeb meem thiab kev kho ntawm nws cov qhov seem ntawm qhov kub siab mus txog lub qhov hnyav), nyob rau hauv lub ncu cua sov, 600 ℃ rau 10min combustion, weighing nws residue.

Cov hmoov tshauv yog qhia raws li feem pua ntawm huab hwm coj: (M1-M0) x 100 / M

M = qhov ceeb thawj ntawm tus qauv,

M1 = qhov hnyav ntawm tshauv thiab qhov hnyav ntawm lub khob,

M0 = qhov hnyav ntawm lub khob

Lub hom phiaj: Txheeb xyuas cov ntsiab lus ntawm cov khoom tsis haum hauv plastics, raws li lub hauv paus rau kev txiav txim qhov tseeb thiab cov khoom cuav thiab lub hauv paus rau kev txiav txim rau kev ua tau zoo ntawm cov ntaub ntawv, xws li: nyob rau hauv cov iav fiber reinforced yas, cov ntoo tshauv siab yuav nce cov yas rigidity , tshav kub tsis txaus, tab sis toughness Txo, ntawm qhov tsis sib xws, nce toughness, nruj kub ua hauj tuaj poob

2. Hws txoj kev ntsuas pa

cov khoom siv uas yuav tsum tau Ntshav: Noo raws kev ntsuas pa / Nom Ntse mete r / Hnyev Analyst

Hws noo: Dej hauv hauv lub nruas.

Lub hauv paus ntsiab lus : infrared sai ntub kev txiav txim siab thiab kev txiav txim siab sai ntawm halogen ya raws.

Cov kev ntsuas qis ntom ntub dej khov : Cov cua kub cua sov poob yog qhov siv cov cua kub thermal cov khoom thermal effect thiab muaj zog uas muaj zog, ntsuas cov dej kom zoo sai sai thiab poob phaus, los ntawm cov pib ntawm cov khoom thiab cov khoom tom qab evaporation ntawm cov ntaub ntawv kuaj dej, npaum li cas ntawm cov dej hauv ib qho kev ntsuas kub.

Halogen Rapid Moisture Test Lub Tswv Yim : Nom Ntsuas Ntsuas Ntsuas Ntsuas Ntsuas Ntsuas Ntsuas Ntsuas ntsuas ntawm lub ntsuas ntawm tib lub sij hawm, qhov ntsuas uas siv txoj raj siv raj ib txoj kab, kev ziab sai ntawm tus qauv, hauv kev ziab, cov kua qaub ncaug poob qis, cov txheej txheem kom qhuav tiav, qhov txiav txim siab zaum kawg ntawm cov dej noo Cov ntsiab lus tseem ceeb raug muab xauv lawm.

Lub hom phiaj ntawm qhov kev ntsuas: Cov ntsiab lus ntawm cov ntsiab lus ntawm cov kab mob yog qhov tseem ceeb tshaj uas cuam tshuam txog kev ua cov khoom siv xws li polyamide (PA) thiab polycarbonate (PC), cov khoom muag thiab khoom cov khoom. Hauv kev txhaj tshuaj molding, yog siv cov khoom ua kom ntau dhau ntawm cov khoom yas rau cov khoom, yuav tsim ib co teeb meem ua, thiab cuam tshuam kawg ntawm cov khoom tiav, xws li: nti tawg, lwm yam khoom kho tshuab
