Amathangi E-Slurry Ensimbini Engagqwali: Ubunjiniyela Obuthuthukile Bezinto Ezilimazayo Nezokugqwala
Ukusebenza nge-slurry—ingxube eminyene, ekhukhulayo kakhulu yezinto eziqinile ezimisiwe noketshezi—kuveza izinselele zobunjiniyela eziyingqayizivele emikhakheni eminingi yezimboni, okuhlanganisa ukucubungula amaminerali, ukukhiqiza amakhemikhali, ukwelashwa kwamanzi angcolile, namagumbi okwenza ama-ceramic noma i-investment casting. Ngenxa yokuthi ama-slurry ahlanganisa ukugqokwa ngemishini okuvela ezinhlayiyeni ezimisiwe kanye nokugqwala kwamakhemikhali okuvela koketshezi olunamandla, iziqukathi ezijwayelekile zensimbi noma zepulasitiki zivame ukubhekana nokucekeleka phansi kwesakhiwo ngokushesha, ukugqwala, nokwehluleka.
Ukubhekana nalezi zimo ezinzima zokusebenza, amathangi e-slurry ensimbi engagqwali abe yindinganiso yegolide ekucubunguleni nasekugcineni izinto ezimbonini. Ehlanganisa amandla okuqina, ukumelana nokugqwala okuzilungisayo, nokuguquguquka kwesakhiwo, imikhumbi yensimbi engagqwali iqinisekisa ukuthembeka kwesikhathi eside futhi inciphisa izindleko zokulungisa ezindaweni ezinzima.
1. Imininingwane Eyisisekelo Yezinto Zokwakha Nokukhethwa Kwe-alloy
Ukukhetha izinga elifanele lensimbi engagqwali kubalulekile ekuqinisekiseni ukuthi ithangi lingakwazi ukumelana nesimo esithile somshini namakhemikhali we-slurry ecutshungulwayo:
● I-AISI 304 / 304L Insimbi Engagqwali: I-alloy ye-austenitic engabizi futhi eguquguqukayo ekahle kuma-slurry anokugqwala okuncane, ukumiswa okujwayelekile okususelwa emanzini, kanye nezinhlelo zokudla noma zezolimo lapho kudingeka khona ukumelana namakhemikhali okulingene.
● I-AISI 316 / 316L Insimbi Engagqwali: Ithuthukiswe ngokungezwa kwe-molybdenum, insimbi engagqwali yezinga le-316 inikeza ukumelana okuphezulu nama-chloride, uketshezi olunamandla olune-asidi, nokugqwala kwamakhemikhali. Ithandwa kakhulu ekucutshungulweni kwamakhemikhali nasezindaweni zezimboni zasolwandle noma ezisogwini.
● I-Duplex ne-Super Duplex Insimbi Engagqwali: Ihlanganisa izakhiwo ezincane ze-austenitic ne-ferritic, ama-alloys e-duplex anikeza amandla amakhulu okudonsa nokumelana okuhle kakhulu nokuqhekeka kokucindezeleka kokugqwala, okubenza balungele ukucutshungulwa kwezimbiwa ezinzima kanye nama-slurry ezimayini aguqula kakhulu.
2. Izici Zokuklama Ezibalulekile Zokusetshenziswa Kwe-Slurry
Ngokungafani nemikhumbi ejwayelekile yokugcina amanzi ahlanzekile, amathangi e-slurry adinga izici zobunjiniyela ezikhethekile ukuvimbela ukuhlala kokuqinile, ukuhlangana, nokuguguleka kwendawo ethile:
● Izinhlelo Zokuxuba Nokushintshana Ezihlanganisiwe: I-slurry iyahlukana ngokwemvelo ngokuhamba kwesikhathi. Amathangi ensimbi engagqwali akhelwe ukusekela ama-bridge mounts asindayo, ama-variable-speed drives, nama-paddles okuxuba akhethekile noma ama-anchor agitators ukuze kugcinwe ukuxubana okufanayo.
● Ukucushwa Okulungiselelwe Kwezansi: Ngokuya ngohlelo oluthile lokusebenza, amathangi e-slurry angaba nezansi zesitya noma izansi eziyigobolondo ukuze kube lula ukukhipha ngokuphelele, kuvinjwe izindawo ezifile, futhi kwenziwe lula ukususwa kwezinsalela noma imijikelezo yokuhlanza ezenzakalelayo (CIP).
● Ukuqedwa Kwezinga Lokuphephula Nokuvikela: Ukupolisha ngomshini noma i-electropolishing kufeza ukuthambeka kwangaphakathi okubushelelezi ($Ra \le 0.8 \, \mu\text{m}$ noma ngaphansi), kuvimbele ukunqwabelana kwezinhlayiya, kunciphise ukugqoka kokungqubuzana, futhi kwenze lula ukugeza okujwayelekile.

Imibuzo Ejwayelekile (FAQ)
Umbuzo: Kungani amathangi ensimbi engagqwali ekhethwa kunepulasitiki noma insimbi yekhabhoni yokugcina i-slurry?
A: Insimbi engagqwali inikeza ukumelana okukhethekile nokugqokwa okungokomshini okuvela ezinhlakeni eziqinile ezimisiwe kanye nokugqwala kwamakhemikhali okuvela oketshezini olunamandla. Ngokungafani nepulasitiki, ayigobi noma ayonakali ngaphansi kwengcindezi yokushisa, futhi ngokungafani nensimbi yekhabhoni, ayidingi ukumbozwa okuqhubekayo ukuvimbela ukugqwala.
Q: Iyiphi izinga lensimbi engagqwali elingcono kakhulu kuma-slurry amaminerali aguqulayo?
A: Okwezinto ezinzima noma amakhemikhali, i-Duplex stainless steel noma i-AISI 316L ivamise ukucaciswa ngenxa yamandla ayo aphezulu okuqina, ubulukhuni, nokumelana okuthuthukisiwe nokugqwala kanye nokuqhekeka kwe-stress corrosion.
Q: Ama-agitator ahlanganisiwe ayithinta kanjani idizayini yesakhiwo samathangi ensimbi engagqwali e-slurry?
A: Ukuxuba nge-torque ephezulu kudala imithwalo ephawulekayo eguqukayo. Amathangi ensimbi engagqwali e-slurry afaka amabhuloho aphezulu aqinisiwe, ama-gusset anesisindo esikhulu, kanye nokunamathiselwe okuqinile kwegobolondo okuklanyelwe ukumunca amandla ajikelezayo nokudlidliza ngesikhathi sokusebenza okuqhubekayo.
Q: Ingabe amathangi ensimbi engagqwali e-slurry angafakwa ngamasudi okulawula izinga lokushisa?
A: Yebo. Izinhlelo eziningi zamakhemikhali nezokucubungula zidinga ukulawulwa kokushisa okunembile. Amathangi ensimbi engagqwali angakhiwa ngamashubhu angaphandle noma amajakhethi okupholisa/okushisisa, ahlanganiswe nezingqimba zokufihla, ukuze kugcinwe amazinga okushisa afanele.
