II-YYP-400DT iLayisha ngokukhawuleza iMelt Flow Indexer(eyaziwa nangokuthi i-Melt Flow Rate Tester okanye i-Melt Index Tester) isetyenziselwa ukulinganisa izinga lokuhamba kweplastiki etyhidiweyo, i-rubber kunye nezinye izinto eziphezulu ze-molecular phantsi koxinzelelo oluthile.
Ungangokulandela amanyathelo asisiseko okusebenzisa okuYYP-400 DT Raid ilayishwa inyibilika isalathisi sokuhamba:
1. Faka idayi kunye nepiston: Faka idayi kwisiphelo esiphezulu sombhobho kwaye uyicinezele phantsi de idibane nepleyiti yokufa kunye nentonga yokulayisha. Emva koko, faka intonga yepiston (indibano) kwi-barrel ukusuka ekupheleni okuphezulu.
2. Ukushisa umgqomo: Xhuma iplagi yamandla kwaye uvule iswitshi yamandla kwipaneli yokulawula. Seta iqondo lobushushu elingaguqukiyo, ixesha lesampulu, ukuphindaphinda kwesampulu, kunye nomthwalo wokulayisha kwiphepha lokumisela iparameter yovavanyo. Emva kokungena kwiphepha eliphambili lovavanyo, cinezela iqhosha lokuqala, kwaye isixhobo siqala ukutshisa. Xa izinga lokushisa lizinza kwixabiso elimiselweyo, gcina ubushushu ubuncinane imizuzu eyi-15.
3. Yongeza isampuli: Emva kwemizuzu eyi-15 yokushisa rhoqo, faka iiglavu ezilungiselelwe (ukuthintela ukutshisa) kwaye ususe intonga yepiston. Sebenzisa i-hopper yokulayisha kunye nentonga yokulayisha ukulayisha ngokulandelelana isampuli esilungisiweyo kwaye uyicinezele kwi-barrel. Yonke inkqubo kufuneka igqitywe kwi-1 ngomzuzu. Emva koko, buyisela ipiston emgqomeni, kwaye emva kwemizuzu emi-4, ungasebenzisa umthwalo oqhelekileyo wokuvavanya kwipiston.
4. Yenza uvavanyo: Beka ipleyiti yeesampuli ngaphantsi kwe-port yokukhupha. Xa intonga yepiston iwela kuphawu olusezantsi lweringi kuyo ikumgangatho ongaphezulu komkhono wesikhokelo, cofa iqhosha elithi RUN. Izinto eziphathekayo ziya kukhutshelwa ngokuzenzekelayo ngokwenani elimiselweyo lamaxesha kunye namaxesha okuthatha isampuli.
5. Rekhoda iziphumo: Khetha iisampuli ze-3-5 ngaphandle kwamaqamu, zizipholise, kwaye uzibeke kwibhalansi. Ukulinganisa ubunzima babo (ibhalansi, echanekileyo ukuya kwi-0.01g), thatha ixabiso eliphakathi, kwaye ucinezele iqhosha lokufaka ixabiso eliphakathi kwiphepha eliphambili lovavanyo. Isixhobo siya kubala ngokuzenzekelayo ixabiso lesantya sokunyibilika kwaye silibonise kwiphepha eliphambili lojongano.
6. Coca izixhobo: Emva kokuba uvavanyo lugqityiwe, linda de yonke into esemgqonyeni ikhutshwe. Gqoka iiglavu ezilungiselelwe (ukuthintela ukutshisa), susa izisindo kunye nentonga yepiston, kwaye uhlambulule intonga yepiston. Cima amandla esixhobo, ukhuphe iplagi yamandla.
