DRK208 Melt Flow Rate Tester

Chithunzi cha DRK208MeltFotsikaRadadyaTester imagwiritsidwa ntchito poyezera kusungunuka kwa polyethylene, polypropylene, polyformaldehyde, ABS resin, polycarbonate, nayiloni fluoroplastic ndi ma polima ena pa kutentha kwakukulu malinga ndi njira yoyesera ya GB3682-2018.Ndizoyenera kupanga ndi kufufuza m'mafakitale, mabizinesi ndi mabungwe ofufuza asayansi.

Makhalidwe akulu:

1,Onjezani gawo lotulutsa:

Kutulutsa doko la diameter:φ 2.095±0.005 mm

Kutalika kwa doko: 8.000±0.005 mm

Diameter ya mbiya yochapira:φ 9.550±0.005 mm

Utali wa mbiya yolipiritsa: 160±0.1 mm

pisitoni ndodo m'mimba mwake: 9.475±0.005 mm

Kutalika kwa mutu wa pisitoni: 6.350±0.100 mm

2,Standard Test Force (Giredi 8)

Kalasi 1: 0.325kg = (ndodo ya pisitoni + thireyi yolemetsa + manja otsekereza kutentha + no. 1 thupi lolemera)

= 3.187 N

Giredi 2:1.200kg =(0.325+ No.2 0.875 kulemera)= 11.77N

Kalasi 3:2.160kg =(0.325+ No.3 1.835 kulemera)= 21.18N

Giredi 4:3.800 kg=(0.325+ no.4 3.475 kulemera)= 37.26N

Giredi 5:5.000 kg=(0.325+ no.5 4.675 kulemera)= 49.03N

Giredi 6:10.000 kg=(0.325+ No.5 4.675 kulemera + No.6 5.000 kulemera)= 98.07N

Kalasi 7:12.000 kg=(0.325+ no.5 4.675 kulemera + No.6 5.000+ No.7 2.500 kulemera)= 122.58N

Giredi 8:21.600 kg=(0.325+ number 2 0.875 kulemera + Number 3 1.835+ Number 4

3.475+5 4.675+6 5.000+7 2.500+8 2.915 kulemera)= 211.82N

Kulakwitsa kwachibale≤0.5%.

3,Kutentha kosiyanasiyana:50-300℃

4,Kutentha kosasintha:±0.5℃.

5,Magetsi:220V±10% 50Hz

6,Malo ogwirira ntchito: kutentha kwapakati ndi 10℃-40℃;Chinyezi chachibale cha chilengedwe ndi 30% -80%;Palibe zowonongera mozungulira, palibe mpweya wamphamvu;Palibe kugwedezeka komanso kusokoneza kwamphamvu kwa maginito kuzungulira.

7,Miyeso ya zida:250×350×600 =(L×W×H）

Kapangidwe ndi mfundo zogwirira ntchito:

Melt flow rate mita ndi mita ya pulasitiki yotulutsidwa.Zili m'mikhalidwe yotentha, yokhala ndi ng'anjo yotentha yotentha kwambiri kuti zinthu zomwe zimayezedwa zikwaniritse kusungunuka.The osungunula wa zinthu kuyeza, pansi pa anatchula kulemera katundu yokoka kudzera ena awiri a dzenje extrusion mayeso.M'mapulasitiki opanga mabizinesi akumafakitale komanso kafukufuku wamabungwe ofufuza asayansi, "kusungunuka (misala) kuthamanga" nthawi zambiri kumagwiritsidwa ntchito kuwonetsa kuchuluka kwamadzi, mamasukidwe akayendedwe ndi zinthu zina zakuthupi za zinthu za polima zomwe zimasungunuka.Chomwe chimatchedwa melting index chimatanthawuza kulemera kwapakati pa gawo lililonse lachitsanzo lomwe linatulutsidwa mu maminiti a 10 a extrusion.

Melt (mass) flow rate mita imawonetsedwa ndi MFR, gawo ndi: g/ 10 min (g/min) Fomula: MFR(θ, mmmm)                      =tref .m/t

Mu chilinganizo: θ——Kutentha kwa mayeso

          mmmm-Kulemera mwadzina Kg

           m —-Unyinji wapakati wa odulidwa g

          tref—-Nthawi yolozera(10 min）, S (zaka 600)

           t—-Nthawi yofikira kudula s

Chidacho chimapangidwa ndi ng'anjo yowotchera ndi kuwongolera kutentha ndikuyika pa fuselage (colum) maziko.

Gawo lowongolera kutentha limatenga microcomputer imodzi-chip kuti isinthe mphamvu ndikuwongolera kutentha, komwe kumakhala ndi mphamvu zotsutsana ndi kusokoneza, kuwongolera kutentha kwambiri komanso kuwongolera kokhazikika.Waya wotenthetsera mu ng'anjoyo amavulazidwa pa ndodo yowotchera molingana ndi lamulo linalake kuti achepetse kutentha ndi kukwaniritsa zofunikira.

Mfundo zofunika kuziganizira:

1,Soketi imodzi yokha yamagetsi iyenera kukhala ndi dzenje la waya, komanso poyatsira modalirika.

2,Ngati pali chiwonetsero chachilendo pa LCD, chiyenera kutsekedwa poyamba, ndiyeno bwererani kutentha kwa mayesero ndikuyamba ntchito.

3,Mu ntchito yachibadwa, ngati ng'anjo kutentha kuposa 300℃, chitetezo cha mapulogalamu, kusokoneza kutentha, ndi alamu.

4,Ngati pali zochitika zachilendo, monga kuwongolera kutentha, sizingawonetse, ndi zina zotero, ziyenera kutsekedwa kuti zisamalidwe,

5,Poyeretsa ndodo ya pisitoni, musakolole ndi zinthu zolimba.
