Melt index yog ib qho ntawm cov cim tseem ceeb los ntsuas cov khoom ntawm plastics.Rau lub raj mis yas hau nrog kev ruaj ntseg siab heev, qhov ntsuas qhov ntsuas ntawm cov ntaub ntawv raw yog qhov tseem ceeb tshwj xeeb.Qhov kev ruaj ntseg ntawm no suav nrog tsis tsuas yog kev ruaj ntseg ntawm lub hau kev ua tau zoo, tab sis kuj tseem tsim thiab molding ntawm lub hau.Hais txog kev ruaj ntseg ntawm cov txheej txheem, Mingsanfeng Cap Mould Co., Ltd.
1. Cov nyhuv ntawm yaj Performance index ntawm lub raj mis lub zog
Qhov siab dua qhov ntsuas qhov ntsuas, nws yooj yim dua rau cov yas ntws, thiab qhov qis zog ntawm cov yas nws tus kheej.Txhua tus neeg yuav tsum nkag siab tias lub zog ntawm cov yaj uas nyuaj rau ntws feem ntau yog siab dua, thiab lub zog ntawm cov yaj uas yooj yim ntws qis dua, yog li cov yaj nws txhais tau hais tias lub zog ntawm lub raj mis lub kaus mom ua los ntawm cov khoom siv polyethylene tsawg. nce.
2. Cov nyhuv ntawm yaj qhov Performance index ntawm seem stability ntawm lub raj mis caps
Qhov siab dua qhov ntsuas qhov ntsuas, qhov yooj yim lub raj mis lub hau yuav deform.Qhov qis dua qhov ntsuas qhov ntsuas, qhov siab dua qhov ruaj khov ntawm lub raj mis lub hau ua los ntawm high-density polyethylene yuav yog.
3. Cov nyhuv ntawm yaj qhov Performance index ntawm lub raj mis cap deformation
Qhov siab dua qhov ntsuas qhov ntsuas, qhov softer lub raj mis cap yog, thiab lub raj mis cap yog yooj yim deform.Tom qab kev thauj mus los ntev, qhov feem ntawm lub raj mis deformation yuav siab dua.Lub raj mis deformed yog ib qho yooj yim kom tau daig ntawm cov kab filling, thiab yaj Nws txhais tau hais tias lub raj mis cap ua los ntawm tsawg-density polyethylene muaj tsawg deformation nyhuv.
4. Cov nyhuv ntawm yaj qhov Performance index ntawm pwm haum raug
Qhov siab dua qhov melt index ntawm high-density polyethylene, qhov yooj yim dua nws yog rau flash kom tshwm nyob rau hauv parting nto thiab txav qhov chaw ntawm pwm.Vim tias qhov fluidity ntawm cov yaj yog zoo, hnav thiab flash yuav pom tseeb dua tshwj xeeb tshaj yog thaum cov pwm khiav mus ntev.Ntawm qhov tsis sib xws, melt index tsawg.Qhov tshwm sim ntawm flash tshwm nyob rau hauv high-density polyethylene yuav qis dua.
5. Cov nyhuv ntawm yaj qhov ntsuas ntawm cov txheej txheem molding
Rau high-density polyethylene nrog ib tug siab yaj Performance index, vim hais tias nws muaj kuj zoo fluidity thiab yog ib qho yooj yim mus extrude, lub raj mis cap tsis yog nws yuav tsis muaj kua nplaum, thiab cov ntsia hlau kub / tsim siab / txhaj tshuaj yuav kuj tsis tshua muaj;rau compression molding cov cuab yeej, cov yaj Performance index yog tsawg Lub high-density polyethylene kuj tsub kom lub molding thiab pwm kaw siab, thiab kuj yuav tsum tau ua kom lub cua sov kub ntawm cov ntsia hlau raws li.
