Ikizamini cya XNR-400C

Ibikoresho byo kwipimisha: Byakoreshejwe mukumenya umuvuduko wogushonga wa polyethylene, polypropilene, polyoxymethylene, resin ya ABS, polyikarubone, fluoroplastique nylon nizindi polymers mubushyuhe bwinshi

Ikizamini cya XNR-400C cyashushanyije ni igikoresho cyo gupima ibintu bitemba bya polimeri ya plastike ku bushyuhe bwinshi ukurikije uburyo bwo gupima GB3682-2018. Ikoreshwa kuri polyethylene, polypropilene, polyoxymethylene, ABS resin, polyakarubone, na fluor ya nylon. Igipimo cyumuvuduko wikigereranyo cya polymers nka plastiki mubushyuhe bwinshi. Irakwiriye kubyara umusaruro nubushakashatsi mu nganda, munganda no mubice byubushakashatsi bwa siyansi.

Ibintu nyamukuru biranga:
1. Igice cyo gukuramo:
Diameter yicyambu gisohoka: Φ2.095 ± 0.005 mm
Uburebure bw'icyambu gisohoka: 8.000 ± 0.005 mm
Diameter ya silinderi yo kwishyuza: Φ9.550 ± 0.005 mm
Uburebure bwo kwishyuza ingunguru: 160 ± 0.1 mm
Piston inkoni yumutwe diameter: 9.475 ± 0.005 mm
Uburebure bwumutwe wa piston: 6.350 ± 0.100mm
2. Imbaraga zipimisha zisanzwe (urwego umunani)
Urwego 1: 0.325 kg = (inkoni ya piston + tray yuburemere + amaboko yubushyuhe + umubiri 1 uburemere) = 3.187N
Urwego 2: 1.200 kg = (0.325 + 0.875 uburemere No 2) = 11.77 N.
Urwego 3: 2,160 kg = (0.325 + No 3 1.835 uburemere) = 21.18 N.
Urwego 4: 3.800 kg = (0.325 + Oya. 4 3.475 uburemere) = 37.26 N.
Urwego 5: 5.000 kg = (0.325 + No 5 4.675 uburemere) = 49.03 N.
Urwego 6: 10.000 kg = (0.325 + Oya 5 4.675 uburemere + No 6 5.000 uburemere) = 98.07 N
Urwego 7: 12.000 kg = (0.325 + Oya 5 4.675 uburemere + Oya 6 5.000 + Oya 7 2.500 uburemere) = 122.58 N
Urwego 8: 21,600 kg = (0.325 + 0.875 uburemere bwa No 2 + 1.835 uburemere bwa No.4 + 3.475 + No.5 4.675 + No.6 5.000 + No.7 2.500 + No.8 2.915 uburemere) = 211.82 N uburemere ugereranije ikosa ≤ 0.5%.
3. Ubushyuhe buringaniye: 50-300 ℃
4. Ubushyuhe burigihe burigihe: ± 0.5 ℃.
5. Amashanyarazi: 220V ± 10% 50Hz
6. Ibidukikije bikora: ubushyuhe bwibidukikije ni 10 ℃ -40 ℃; ugereranije n'ubushuhe bwibidukikije ni 30% -80%; nta buryo bubora bubora hirya no hino, nta kirere gikomeye; nta kunyeganyega hirya no hino, nta guhuza imbaraga gukomeye.

Imiterere n'ihame ry'akazi:
Ikigereranyo cyo gutembera gushonga ni metero ya plastiki ikuweho. Ikoresha itanura ryubushyuhe bwo hejuru kugirango ikintu cyapimwe kigere kumashanyarazi munsi yubushyuhe bwagenwe. Ikintu cyo kwipimisha muri iyi miterere yashizwemo ikorerwa ikizamini cyo gukuramo binyuze mu mwobo muto wa diameter runaka munsi yuburemere bwuburemere bwateganijwe. Mubikorwa bya pulasitiki byinganda zinganda nubushakashatsi bwibice byubushakashatsi bwa siyansi, "umuvuduko wo gutemba (mass) umuvuduko" ukunze gukoreshwa kugirango ugaragaze imiterere yumubiri wibikoresho bya polymer muburyo bwashongeshejwe nkamazi nubwiza. Icyitwa gushonga cyerekana uburemere buringaniye bwa buri gice cya extrudate ihindurwamo ingano yiminota 10.
Ikigereranyo cyo gutembera (misa) igipimo cyerekanwa na MFR, igice ni: garama / iminota 10 (g / min), naho formula ikagaragazwa na: MFR (θ, mnom) = tref .m / t
Muri formula: θ—— ubushyuhe bwikizamini
mnom - umutwaro wizina Kg
m —— impuzandengo ya misa yaciwe g
tref —— igihe cyo gukoreshwa (10min), S (600s)
T —— gabanya igihe s
Urugero: Urutonde rwicyitegererezo cya plastike rugabanywa buri masegonda 30, kandi ibisubizo rusange bya buri gice ni: 0.0816 g, 0.0862 g, 0.0815 g, 0.0895 g, na 0.0825 g.
Impuzandengo m = (0.0816 + 0.0862 + 0.0815 + 0.0895 + 0.0825) ÷ 5 = 0.0843 (g)
Simbuza formula: MFR = 600 × 0.0843 / 30 = 1.686 (g / iminota 10)
Iki gikoresho kigizwe nitanura rishyushya hamwe na sisitemu yo kugenzura ubushyuhe kandi igashyirwa munsi yumubiri (inkingi).
Igice cyo kugenzura ubushyuhe gikoresha imbaraga imwe ya chip ya microcomputer hamwe nuburyo bwo kugenzura ubushyuhe, bufite imbaraga zikomeye zo kurwanya interineti, kugenzura ubushyuhe bukabije, no kugenzura bihamye. Umugozi wo gushyushya mu itanura wakomerekejwe ku nkoni yo gushyushya ukurikije itegeko runaka kugirango ugabanye ubushyuhe bwa gradient kugirango wuzuze ibisabwa bisanzwe.
