Momwe mungagwiritsire ntchito kutsitsa mwachangu kusungunuka kwa indexer?

TheYYP-400DT Rapid Loading Melt Flow Indexer(yomwe imadziwikanso kuti Melt Flow Rate Tester kapena Melt Index Tester) imagwiritsidwa ntchito kuyeza kuthamanga kwa pulasitiki yosungunuka, mphira ndi zinthu zina zapamwamba zamamolekyu pansi pa zovuta zina.

Muthakutsatira njira zofunika kugwiritsa ntchito iziYYP-400 DT Raid yotsegula cholozera chosungunuka chosungunuka:

1. Ikani kufa ndi pisitoni: Lowetsani kufa kumapeto kwa mbiya ndikuisindikiza pansi mpaka itakhudza mbale yakufa ndi ndodo yotsegulira. Kenako, ikani ndodo ya pisitoni (msonkhano) mu mbiya kuchokera kumapeto.

2. Preheat mbiya: Lumikizani pulagi yamagetsi ndikuyatsa chosinthira mphamvu pagawo lowongolera. Khazikitsani kutentha kosalekeza, nthawi yachitsanzo, kusanja pafupipafupi, ndi kutsitsa katundu patsamba lokhazikitsira zoyeserera. Mukalowa patsamba lalikulu la mayeso, dinani batani loyambira, ndipo chidacho chimayamba kutentha. Pamene kutentha kukhazikika pamtengo wokhazikitsidwa, sungani kutentha kwa mphindi 15.

3. Onjezani chitsanzo: Pambuyo pa mphindi 15 za kutentha kosalekeza, valani magolovesi okonzeka (kuteteza kutentha) ndi kuchotsa ndodo ya pistoni. Gwiritsani ntchito chopondera ndi ndodo yotsegulira kuti muyike motsatizanatsatidwe katsanzo kokonzedwa ndikukankhira mumbiya. Ntchito yonseyo iyenera kumalizidwa mkati mwa mphindi imodzi. Kenako, bwezerani pisitoni mu mbiya, ndipo pakatha mphindi 4, mutha kuyika pisitoni yoyezetsa.

4. Chitani mayeso: Ikani mbale yoyeserera pansi pa doko lotulutsa. Ndodo ya pisitoni ikatsikira pachidindo chakumunsi kwa mpheteyo kukhala yofanana ndi chapamwamba cha manja owongolera, dinani batani la RUN. Zinthuzi zizingosedwa zokha molingana ndi kuchuluka kwa nthawi komanso nthawi zotsatirira.

5. Lembani zotsatira: Sankhani 3-5 zitsanzo zopanda thovu, kuziziziritsa, ndi kuziyika pamlingo. Yezerani kulemera kwake (kuchuluka, kolondola kufika pa 0.01g), tengani mtengo wapakati, ndikusindikiza batani lolowetsamo mtengo patsamba lalikulu la mayeso. Chidacho chimangowerengera mtengo wosungunuka wosungunuka ndikuwonetsa pa tsamba lalikulu la mawonekedwe.

6. Tsukani zida: mayeso akamaliza, dikirani mpaka zonse zomwe zili mumgololo zitafinyidwa. Valani magolovesi okonzeka (kupewa kuyaka), chotsani zolemera ndi pisitoni ndodo, ndikuyeretsa ndodo ya pisitoni. Zimitsani mphamvu ya chida, chotsani pulagi yamagetsi.
