Ezitshalweni zokukhiqiza i-caprolactam, ezindaweni zokukhiqiza i-polyamide, kanye nasezindaweni zokukhiqiza amakhemikhali, ukulinganisa okunembile kokuhlushwa kwe-caprolactam kubalulekile ukuze kusetshenziswe izinqubo zokukhiqiza ze-caprolactam eziphumelelayo. Ukugcina ukuhlushwa kwe-caprolactam okuhle ngesikhathi sokuhlukaniswa kwesigaba, ukukhishwa, kanye nokufakwa kwe-polymer kuqinisekisa i-Nylon 6 ehlanzekile kakhulu, kunciphisa imfucuza, futhi kuhlangabezana nezindinganiso zomthetho eziqinile.
Ukuqapha ukuhlushwa kwe-CPL okungaguquki kungaphazamisa ukusebenza, kwandise izindleko, futhi kubeke engcupheni ukungalandeli imithethonqubo yezemvelo, njengokukhishwa kwe-nitrous oxide (N₂O). Hlanganisa imishini yakho neimitha yokuhlushwa emugqeniukuthuthukisa ukusebenza kahle, ukunciphisa izindleko, nokuqinisekisa ukuthobela imithetho emisebenzini yakho.
Ukubuka konke kwenqubo yokukhiqiza i-Caprolactam
Inqubo yokukhiqiza i-caprolactam ihilela ukuhlanganiswa kwe-cyclohexanone oxime, kulandelwe ukuhlelwa kabusha kwe-Beckmann kusetshenziswa i-sulfuric acid noma i-oleum, ukuncishiswa kwe-ammonia ukuze kwakhiwe i-ammonium sulphate egcwalisiwe, kanye nokuhlanzwa ngokuhlukaniswa kwesigaba, ukukhipha, ukuhluzwa, kanye ne-crystallization. Amamitha okuhlushwa kwe-Caprolactam kanye namamitha okuhlushwa kwe-CPL aqapha ukuhlushwa kwe-caprolactam ngesikhathi sokukhishwa kanye nokuhwamuka, kuyilapho amamitha okuhlushwa kwe-oleum eqinisekisa ukuhlushwa okunembile kwe-oleum (0–30 wt% ku-10–60°C) esinyathelweni sokuhlelwa kabusha. Ukuqapha okunembile kokuhlushwa kwe-caprolactam kubalulekile ukuze kufezwe i-caprolactam ehlanzekile kakhulu yokukhiqiza i-polyamide, kuncishiswe ama-monomers asele, futhi kulungiselelwe ukuhlushwa kwe-ammonium sulphate egcwalisiwe ngesikhathi sokuhlukanisa isigaba.
Ubunzima Bobuchwepheshe Ekulinganisweni Kokuhlushwa kwe-Caprolactam
Ukungcola Kwezinzwa Nokugqwala
Indawo yamakhemikhali enzima yezinqubo zokukhiqiza i-caprolactam, ehilela i-oleum, i-sulfuric acid, kanye ne-ammonium sulphate, ibangela ukungcola kanye nokugqwala kumamitha okuhlushwa e-caprolactam kanye namamitha okuhlushwa e-oleum. Amadiphozithi avela kokungcola noma izixazululo eziqinile anciphisa ukunemba kwenzwa, okudinga ukuhlanzwa noma ukushintshwa njalo, okwandisa isikhathi sokungasebenzi kanye nezindleko zokulungisa ezindaweni zokukhiqiza i-polyamide.
Ukukhishwa Okungaguquguquki kanye Nokwenziwa Kwe-Polymerization
Ukuguquguquka kokuhlushwa kwe-caprolactam ngesikhathi sokuhlukaniswa kwesigaba noma ukukhishwa kunganciphisa isivuno kanye nobumsulwa. Ekukhiqizweni kwe-polyamide, ukuqapha kokuhlushwa kwe-CPL okungaguquki kuholela kuma-monomers aphezulu asele, okuthinta amandla okudonsa kanye nezindleko zokubuyisa imfucuza ezandayo.
Izingozi Zokulawula Nokuphepha
Ukulinganisa ukuhlushwa kwe-caprolactam okungalungile noma ukuqapha ukuhlushwa kwe-oleum kungaholela ekukhishweni ngokweqile kwe-N₂O noma ukuphathwa okungalungile kokuhlushwa kwe-ammonium sulphate, okubangela ukungahambisani nemithethonqubo efana nezindinganiso ze-REACH noma ze-EPA. Izingozi zokuphepha ezivela ekuphathweni kabi kwe-oleum zigcizelela isidingo sokuqapha okunembile.
Izixazululo Zokulawula Ukuhlushwa Kwe-Caprolactam Emugqeni
Imitha Yokuhlushwa ye-Ultrasonic ye-Lonnmeter
I-Lonnmeterimitha yokuhlushwa kwe-ultrasonicUbuchwepheshe be-ultrasonic be-harness bunikeza ukunemba okuphezulu, obungathinteki ngamabhamuza, igwebu, noma i-viscosity. Amamitha e-Ultrasonic avelele ekuhlukaniseni isigaba, elinganisa ukuhlushwa kwe-caprolactam kanye nokuhlushwa kwe-ammonium sulphate okugcwele. Inikeza ukufundwa kwezinga lokushisa, ukuhlushwa kanye nesivinini somsindo ngokusebenzisa imiphumela yeziteshi ezimbili.
Umkhiqizi iLonnmeter uphinde anikeze izinketho ze-ODM, ezivumela amakhasimende ukuthi akhethe izinto, ubude, izinga lokushisa, ingcindezi, izinhlobo zokuxhumeka ngisho negobolondo langaphandle. Ngaphezu kwalokho, kwenza kube lula ukuhlanganiswa nezinhlelo ze-DCS/PLC ukuze kube nezixhumi ezisebenzayo ezifana ne-RS485, i-Modbus, i-Profibus-DP, i-Bluethooth 5.3, isignali engu-4-20mA, njll.
Ukuhlanganiswa nezinhlelo zokuqapha eziku-inthanethi zesikhathi sangempela
Amamitha okuhlushwa e-CPL angaphakathi kanye namamitha okuhlushwa e-polyamide ahlinzeka ngedatha yesikhathi sangempela, ehlanganiswa nezinhlelo zokulawula ezisatshalaliswa (i-DCS) noma abalawuli be-logic abahlelekayo (i-PLC) ukuze balungise ukulinganisa kwe-caprolactam ngokuzenzakalelayo. Lokhu kuthuthukisa izinqubo zokukhiqiza i-caprolactam, kunciphisa ukusetshenziswa kwamandla, futhi kuqinisekisa ikhwalithi ye-Nylon 6 ehambisanayo.
Ukubhekana Nezinselele Zokusebenza Nokuthobela Imithetho
Ukunciphisa Isikhathi Sokungasebenzi Kokulungisa
Amamitha okuhlushwa e-Caprolactam anezici zokulungisa ezibikezelayo kanye nezikhawu zesevisi ezinde anciphisa isikhathi sokungasebenzi ezinqubweni zokukhiqiza i-caprolactam. I-Diagnostics ixwayisa ochwepheshe ngokungcola noma ukukhukhuleka okungenzeka, okuvumela ukulungiswa okusheshayo ezindaweni zokukhiqiza i-polyamide.
Ukuqinisekisa Ukuthobela Imithetho
Amamitha okuhlushwa kwe-oleum kanye namamitha okuhlushwa kwe-CPL anokuqoshwa kwedatha okuqinile kanye nokuhlanganiswa kwe-DCS/PLC kuqinisekisa ukuhambisana nemithethonqubo yemvelo. Ukuqapha ukuhlushwa kwe-caprolactam ngesikhathi sangempela kunciphisa ukukhishwa kwe-N₂O futhi kuthuthukisa ukuhlushwa kwe-ammonium sulphate egcwalisiwe, kunciphisa imfucuza kanye nezingozi zomthetho.
Imibuzo Evame Ukubuzwa
