Cyclopentane Series High Pressure Foaming Machine
Izinto ezimnyama nezimhlophe zixubene ne-premix ye-cyclopentane ngokusebenzisa inhloko yesibhamu somjovo womshini we-foaming ocindezelayo ophezulu futhi ifakwe ku-interlayer phakathi kwegobolondo langaphandle kanye negobolondo langaphakathi lebhokisi noma umnyango.Ngaphansi kwezimo ezithile zokushisa, i-polyisocyanate (isocyanate (-NCO) ku-polyisocyanate) kanye ne-polyether ehlangene (i-hydroxyl (-OH)) ekuphenduleni kwamakhemikhali ngaphansi kwesenzo se-catalyst ukukhiqiza i-polyurethane, ngenkathi ikhulula ukushisa okuningi.Ngalesi sikhathi, i-ejenti enegwebu (i-cyclopentane) exutshwe ngaphambili ku-polyether ehlanganisiwe iqhubeka i-vaporized futhi i-polyurethane iyanwetshwa ukuze igcwalise igebe phakathi kwegobolondo ne-liner.
Izici:
1. I-metering inembile, futhi idivayisi ye-metering enembe kakhulu iyamukelwa, futhi ukunemba kokulinganisa kuphezulu.I-meteringpump ithatha uxhumano kazibuthe, olungasoze lwavuza futhi lunempilo ende yesevisi.
2. Idivayisi yokuxuba ithatha uhlobo lwe-L-high-pressure self-clean mixing head, ububanzi be-nozzle buyalungiseka, futhi ukucindezela okuphezulu kwenza inkungu ukuze ixube ngokulinganayo.
3. Idivayisi yokushintsha umjikelezo wengcindezi ephezulu nephansi, ukushintsha phakathi kokusebenza nokungasebenzi.
4. Idivayisi yezinga lokushisa isebenzisa umshini ohlanganisiwe wokupholisa nokushisisa ukuze ulawule izinga lokushisa elingaguquki, ngephutha elingu-<±2°C.
5. Ukulawula ugesi, kusetshenziswa isikrini sokuthinta esingu-10-intshi, isilawuli semojula ye-PLC, izinga lokushisa elilawulayo, ingcindezi nokugeleza okuthululwayo, ukugcina izindlela zokupheka ezingama-99, kanye nezinga eliphezulu lokuzishintshanisa.
6. Ithangi lempahla: ithangi le-polyether/cyclopentane (igumbi lezinto ezimhlophe elakhelwe ngabanye), elinomtshina wokuhlushwa kanye nesistimu yokukhipha amandla aphezulu.
Ikhanda lokuxuba umfutho ophezulu:
I-South Korea ingenise i-DUT yokuxuba ikhanda enengcindezi ephezulu isebenzisa idizayini yokuzihlanza kanye nesimiso sokuxuba sokushayisana komfutho ophezulu.
Ukuxubana kokushayisana komfutho ophezulu ukuguqula amandla okucindezela ezingxenyeni abe amandla e-kinetic, ukuze izingxenye zithole isivinini esikhulu futhi zingqubuzane, ngaleyo ndlela zikhiqize ukuxutshwa okwanele.Ikhwalithi yokuxuba ihlobene nezici zezinto zokusetshenziswa (i-viscosity, izinga lokushisa, ukuminyana, njll.), ingcindezi yomjovo kanye nomehluko wengcindezi yomjovo.Ikhanda lokuxuba elinomfutho ophezulu alidingi ukuhlanzwa ukuze kuthululwe kaningi.Kunconywa ukugcina nokushintsha uphawu lwekhanda izikhathi ezingu-400,000.
Umkhawulo wengcindezi nohlelo lokulawula:
Ingcindezi yokusebenza ye-polyether polyol kanye nezingxenye ze-isocyanate ilawulwa ku-6-20MPa;uma ingcindezi yokusebenza idlula leli banga, okokusebenza kuzocisha ngokuzenzakalelayo, kukhale i-alamu futhi kubonise umyalezo wephutha "wengcindezi yokusebenza iphansi kakhulu" noma "ingcindezi yokusebenza iphezulu kakhulu".
Ingcindezi yokugcina yokuphepha yengxenye yephampu yemitha isethwe ku-22MPa ngevalvu yokuphepha.I-valve yokuphepha inomsebenzi wokuvikela wemishini ukuze kuqinisekiswe ukuphepha kwepompo yemitha kanye nesistimu.
Ingcindezi yangaphambili yephampu yemitha yengxenye isethelwe ku-0.1MPa.Uma i-pre-pressure iphansi kunevelu ebekiwe, okokusebenza kuzoma ngokuzenzakalelayo bese kuhlaba umkhosi futhi kubonise umlayezo wephutha "we-pre-pressure iphansi kakhulu".
Isistimu ye-pneumatic:
Idivayisi yokugcina umfutho wethangi iqukethe ivalvu yokunciphisa umfutho we-nitrogen, ifreyimu yokuxhuma kanye ne-pressure relay.Uma umfutho we-nitrogen uphansi kunevelu ebekiwe ye-pressure relay, okokusebenza kuzocisha ngokuzenzakalelayo futhi kunikeze i-alamu.Ngesikhathi esifanayo, i-polyol/cyclopentane tank feed valve kanye ne-outlet I-valve yokuphakelayo ivaliwe, inqamula amapayipi okungena nokuphuma kwe-cyclopentane.
Izingxenye zokulawula zenziwe nge-pneumatic triplet, i-valve yomoya, i-muffler, njll, esetshenziselwa ukulawula umsebenzi wesistimu;
