Ezitshalweni zokukhiqiza i-caprolactam, izikhungo zokukhiqiza i-polyamide, nezindawo zokukhiqiza amakhemikhali, ukulinganisa okuqondile kwe-caprolactam kubalulekile ukuze kusebenze izinqubo zokukhiqiza i-caprolactam. Ukugcina i-caprolactam egxilile ngesikhathi sokuhlukaniswa kwesigaba, ukukhipha, kanye ne-polymerization kuqinisekisa ukuhlanzeka okuphezulu kweNylon 6, kunciphisa ukungcola, futhi kuhlangabezana nezindinganiso eziqinile zokulawula.
Ukuqapha okugxilile kwe-CPL okungaguquki kungaphazamisa ukusebenza, kwandise izindleko, kanye nengozi yokungathobeli imithetho yemvelo, njengokukhishwa kwe-nitrous oxide (N₂O). Hlanganisa imishini yakho ngeimitha yokuhlushwa emgqeniukuthuthukisa ukusebenza kahle, ukunciphisa izindleko, kanye nokuqinisekisa ukuthobela imisebenzi yakho.
Uhlolojikelele Lwenqubo Yokukhiqiza I-Caprolactam
Inqubo yokukhiqiza i-caprolactam ihlanganisa ukuhlanganiswa kwe-cyclohexanone oxime, kulandelwa ukuhlelwa kabusha kwe-Beckmann kusetshenziswa i-sulfuric acid noma i-oleum, i-neutralization ne-ammonia ukuze yakhe i-ammonium sulphate egcwele, nokuhlanzwa ngokuhlukaniswa kwesigaba, ukukhipha, i-distillation, ne-crystallization. Amamitha wokugxilisa we-Caprolactam kanye namamitha okugxilisa we-CPL aqapha ukugxilwa kwe-caprolactam ngesikhathi sokukhipha kanye nokuhwamuka, kuyilapho amamitha okugxilisa i-oleum aqinisekisa ukugxila kwe-oleum okunembile (0–30 wt% ku-10–60°C) esinyathelweni sokuhlela kabusha. Ukuqapha okunembile kwe-caprolactam kubalulekile ukuze kuzuzwe ukuhlanzeka okuphezulu kwe-caprolactam yokukhiqiza i-polyamide, ukunciphisa ama-monomer asele, nokwandisa ukugxila kwe-ammonium sulphate egcwele ngesikhathi sokuhlukaniswa kwesigaba.
Ubunzima Bezobuchwepheshe ku-Caprolactam Concentration Measurement
Ukonakala Kwezinzwa kanye Nokugqwala
Imvelo yamakhemikhali enokhahlo yezinqubo zokukhiqiza i-caprolactam, ehlanganisa i-oleum, i-sulfuric acid, ne-ammonium sulphate, ibangela ukungcola nokugqwala kumamitha wokugxilisa we-caprolactam kanye namamitha wokuhlushwa we-oleum. Amadiphozithi asuka ekungcoleni noma ezixazululweni ze-viscous anciphisa ukunemba kwezinzwa, ezidinga ukuhlanzwa njalo noma ukushintshwa, okwandisa izindleko zesikhathi sokuphumula nezokulungisa ezindaweni zokukhiqiza i-polyamide.
Ukukhipha Okungahambisani Nokupolymerization
Ukushintshashintsha kokugxila kwe-caprolactam ngesikhathi sokuhlukaniswa kwesigaba noma ukukhishwa kunganciphisa isivuno nobumsulwa. Ekwenziweni kwe-polyamide, ukuqapha kokugxilisa ingqondo kwe-CPL okungaguquki kuphumela kuma-monomer asele aphezulu, okuthinta amandla okuqina nokukhulisa izindleko zokutholwa kwemfucuza.
Izingozi Zokulawula Nokuphepha
Ukulinganisa okungalungile kwe-caprolactam noma ukuqapha ukugxilisa kwe-oleum kungaholela ekukhishweni kwe-N₂O ngokweqile noma ukulawulwa okungafanele kwe-ammonium sulphate egcwele i-ammonium sulphate, kubeke engcupheni yokungathobeli imithetho efana ne-REACH noma amazinga e-EPA. Izingozi zokuphepha ekuphathweni kabi kwe-oleum ziphinde zigcizelele isidingo sokuqapha okunembayo.
Izixazululo ze-Inline Caprolactam Concentration Control
I-Lonnmeter Ultrasonic Concentration Meter
I-Lonnmeterimitha yokuhlushwa ye-ultrasonicUbuchwepheshe be-harness ultrasonic bunikeza ukunemba okuphezulu, okungathintwa amabhamuza, igwebu, noma i-viscosity. Amamitha e-Ultrasonic ahamba phambili ekuhlukaniseni isigaba, ukulinganisa ukuhlushwa kwe-caprolactam kanye nokuhlushwa kwe-ammonium sulphate egcwele.

Umkhiqizi we-Lonnmeter uphinde ahlinzeke ngezinketho ze-ODM, ezivumela amakhasimende ukuthi akhethe impahla, ubude, izinga lokushisa, ingcindezi, izinhlobo zokuxhuma ngisho negobolondo langaphandle. Ngaphezu kwalokho, yenza kube lula ukuhlanganiswa nezinhlelo ze-DCS/PLC zokusebenzelana okusebenzayo njenge-RS485, Modbus, Profibus-DP, Bluethooth 5.3, 4-20mA isignali, njll.
Ukuhlanganiswa ne-Real-Time Inline Monitoring Systems
Amamitha wokugxilisa we-CPL e-Inline kanye namamitha okugxilisa we-polyamide ahlinzeka ngedatha yesikhathi sangempela, ehlanganisa nezinhlelo zokulawula ezisabalalisiwe (DCS) noma izilawuli ze-programmable logic (PLC) ukuze kulungiswe umthamo we-caprolactam ngokuzenzakalelayo. Lokhu kuthuthukisa izinqubo zokukhiqiza i-caprolactam, kunciphisa ukusetshenziswa kwamandla, futhi kuqinisekisa ikhwalithi yeNylon 6 engaguquki.
Ukubhekana Nezinselele Zokusebenza Nokuhambisana
Ukunciphisa Isikhathi Sokuphumula Sokulungisa
Amamitha wokugxilisa we-Caprolactam anezici zokunakekela ezibikezelayo nezikhawu zesevisi ezinde anciphisa isikhathi sokuphumula ezinqubweni zokukhiqiza i-caprolactam. I-Diagnostics ixwayisa ochwepheshe mayelana nokonakala okungaba khona noma ukukhukhuleka, okuvumela ukunakekelwa okusebenzayo ezikhungweni zokukhiqiza ze-polyamide.
Ukuqinisekisa Ukuthotshelwa Kwemithetho
Amamitha okugxilisa i-Oleum kanye namamitha okugxilisa i-CPL anokufakwa kwedatha okuqinile kanye nokuhlanganiswa kwe-DCS/PLC kuqinisekisa ukuthotshelwa kwemithetho yemvelo. Ukuqapha ukugxiliswa kwe-caprolactam kwesikhathi sangempela kunciphisa ukukhishwa kwe-N₂O futhi kuthuthukisa ukugxiliswa kwe-ammonium sulphate egcwele, kunciphisa imfucuza kanye nezingozi zokulawula.
Imibuzo Evame Ukubuzwa
Ungayilawula kanjani i-Inline Concentration yeCaprolactam?
Ukulawula ukugxiliswa kwe-caprolactam emgqeni kudinga amamitha wokugxilisa we-caprolactam ngezinto ezimelana nokugqwala kanye nokuqapha kwesikhathi sangempela. Hlanganisa amamitha wokugxilisa we-CPL nezinhlelo ze-DCS/PLC zomthamo ozenzakalelayo, sebenzisa ubuchwepheshe be-ultrasonic noma i-refractometric ukuze uthole ukunemba.
Imaphi Amamitha Angcono Kakhulu Wokugxilwa Kwe-Caprolactam Okukhiqiza I-Caprolactam?
Amamitha wokuhlushwa we-caprolactam angcono kakhulu wezinqubo zokukhiqiza i-caprolactam yimitha yokuhlushwa ye-ultrasonic engagqwali noma i-refractometer. Amamitha wokugxilisa we-Polyamide anokuhlanganiswa kwe-DCS/PLC nezici zokulondoloza ezibikezelayo zilungele izikhungo zokukhiqiza i-polyamide.
Ngibhekana Kanjani Nokuphazamiseka Kwezinzwa Ekukhiqizeni I-Caprolactam?
Ukungcoliswa kwezinzwa ezitshalweni zokukhiqiza i-caprolactam kungancishiswa ngokuqapha okunembe kakhulu ukuze kuvinjelwe ukonakala kanye nokukala ekukhiqizeni.
Ukulawula ukugxila kwe-caprolactam esemgqeni ezitshalweni zokukhiqiza i-caprolactam kanye nezindawo zokukhiqiza i-polyamide kubalulekile ezinqubweni zokukhiqiza ezisebenzayo ze-caprolactam. Ukuqapha kwesikhathi sangempela, izinzwa ezimelana nokugqwala, nokulawula okuqhutshwa ukuhlaziya kuthuthukisa ukuhlukaniswa kwesigaba kanye nokulawulwa okugcwele kwe-ammonium sulphate.
Xhumana nomhlinzeki othembekile we-Lonnmeter ukuze uthole amamitha wokugxilisa we-caprolactam ukuze ucele ikhotheshini noma idemo futhi uphakamise ukusebenza kwakho. Kuyenzeka ukuthi abafake izicelo abaphezulu abayi-1000 bathole isampula yamahhala uma uhlangabezana nemibandela yethu. Cela ikhotheshini khona manje ukuze wazi imininingwane eyengeziwe mayelana nenqubo yethu yesampula yamahhala.
