Inkqubo yonyango lwesanti ye-resin

Inkqubo yonyango lwesanti ye-resin
Inkqubo yokucoca isanti yentlabathi yentlabathi yentlabathi yentlabathi (eqhelekile ibhekisa kwisanti egayiweyo enezincamathelisi ezifana ne-furan resin okanye i-alkaline phenolic resin) yenye yetekhnoloji engundoqo kwiindibano zocweyo zanamhlanje zokuphosa. Eyona njongo yayo kukuhlaziya ngokufanelekileyo, ukuvuselela, kunye nokusebenzisa isanti endala ukunciphisa iindleko, ukuqinisekisa umgangatho wokuphosa, kunye nokunciphisa ukungcoliseka kwendalo.
Ngokungafaniyo nesanti yejeli ye-silica, ifilimu encamathelayo ye-organic yesanti ye-resin iya kutsha kwaye ibe brittle emva kokugalelwa, kodwa ayipheli ngokupheleleyo. Ngoko ke, undoqo wenkqubo yokonyango kukususa ifilimu ye-resin ye-inert kunye nokungcola ebusweni bentlabathi endala.
Nantsi inkqubo yonyango epheleleyo kunye nezixhobo eziphambili zentlabathi yentlaka (ukuthatha eyona ixhaphakileyo isetyenziswa kwintlabathi ye-furan self{0}}eyenza lukhuni njengesanti):
1. Ukuhamba kwenkqubo engundoqo: "Umjikelo wesanti" opheleleyo
Umgca wokuvelisa isanti yentlabathi eqhelekileyo yinkqubo evaliweyo -, ngolu hlobo lulandelayo:
Isanti endala → Ukutyumza → Ukwahlulwa kwemagnethi → Uvavanyo → Uhlaziyo olusisiseko → Ukuvuselelwa okwesibini → Ulawulo lobushushu besanti → Ukuxuba → Ukuphosa → Ukususwa kwesanti → Isanti endala
2. Iinkcazo ezineenkcukacha zenkqubo nganye kunye nezixhobo eziphambili
1. Ukususwa kwesanti kunye necandelo-lonyango kwangaphambili
Injongo: Ukwahlula i-castings kwiibhloko zesanti kunye nokwenza ukucoca kwangaphambili.
Izixhobo eziphambili:
* Umatshini wokususa isanti ongcangcazelayo / I-Crusher: Yaphula amagaqa entlabathi amakhulu ukwahlula iibhloko zesanti kwisanti kunye neebhokisi zesanti.
* Isahluli semagnethi ({0}}ulungiselelo lwamanqanaba amaninzi): Ngesiqhelo ukuseta ezininzi (ezifana nasemva kokususwa kwesanti naphambi kokuhlaziywa kwakhona) emgceni, kususwa ngamandla ubumdaka obuzibuthe be-iron (obufana ne-flash, iimbotyi ze-iron, iinzipho ze-iron, njl. njl.) ukukhusela izixhobo ezilandelayo.
*Isikrini esingcangcazelayo: Susa{0}}ubumdaka obungangobumagnethi bebhloko enkulu obunje ngeecores, iibhloko zeplanga, amaphepha eplastiki, njalo njalo.
2. Icandelo lokuhlaziya isanti (undoqo)
Esi sisitshixo sokumisela umgangatho wesanti ehlaziyiweyo kunye neendleko zenkqubo. Ukuhlaziywa kwesanti ye-resin yanamhlanje ngokubanzi kwamkela "ukuvuselelwa komatshini okomileyo", yahlulwe ngamanqanaba amabini okanye ngaphezulu:
Uhlaziyo olusisiseko (-ngaphambi kohlaziyo / oluphambili):
* Injongo: Ngokungqubana okukhulu kunye nongquzulwano, susa uninzi (malunga ne-70-80%) yefilimu ye-resin enqabileyo ebusweni bentlabathi.
* Izixhobo eziphambili:
Ukungcangcazela umatshini wokuhlaziya: Unemisebenzi yokutyumza kunye neyokuqala yokuhlaziya. Ngokungcangcazela, amasuntswana esanti ayangqubana.
Umatshini wokuhlaziya i-Centrifugal: Usebenzisa{0}}isantya esiphezulu sokujikeleza kwerotha ukuvelisa ukuhamba kwesanti, kubangela impembelelo yesantya esiphezulu kunye nokukhuhlana phakathi kwamasuntswana esanti kunye{2}}nesixhobo esixhathisayo{2}}esisebenzayo, ngoku sesona sixhobo siphambili nesisebenzayo sokuhlaziya.
Ukuhlaziywa okwesibini (ukuhlaziywa kakuhle):
* Injongo: Ngokuqhubekayo susa ifilimu ye-resin eseleyo kunye nomgubo ocolekileyo, kwaye ucolise amasuntswana esanti ukunciphisa inani le-resin eyongeziweyo kunye nokuphucula ukuhamba kwesanti yokubumba.
* Izixhobo eziphambili:
Umatshini wokuhlaziya impembelelo yokuqukuqela komoya: Usebenzisa-umoya ohamba ngesantya esiphezulu (odla ngokusuka kwifeni) ukuqhuba amasuntswana esanti ukuze angqubane ngamandla kwigumbi lokuhlaziya, enze "ungquzulwano oluthambileyo" ukujikeleza amasuntswana esanti. Lo ngundoqo wohlaziyo lwesibini.
Umatshini wokuhlaziya i-friction: Ngeendlela zoomatshini ukwenza ukuba amasuntswana esanti angqubane.
Kabini-idiski epholileyo / Amanzi{1}}igubu elipholileyo: Ezinye izixhobo zokupholisa ozikhethelayo.
3. Icandelo lolawulo lobushushu besanti (isitshixo sokuqinisekisa ukuxubana kwesanti)
Injongo: Indlela yokunyanga intlaka ibuthathaka kakhulu kubushushu. Iqondo lobushushu lesanti ehlaziyiweyo lihlala liphezulu kakhulu (linokugqithisa i-40-50 idigri ehlotyeni okanye ngexesha lemveliso eqhubekayo), kwaye kufuneka ipholiswe kwaye izinze phakathi koluhlu olufanelekileyo lwama-25-35℃ukuqinisekisa ukuzinza kwe-resin yokongeza isixa kunye nesantya sokunyanga kwinkqubo yokuxuba elandelayo.
Izixhobo eziphambili:
• Ibhedi epholileyo yokubilisa: Esona sixhobo siqhelekileyo sisetyenziswa ngokufanelekileyo. Ukuvuthuza emoyeni obandayo ukwenza amasuntswana esanti kwimo ebilayo enolwelo, ngokudibana ngokupheleleyo nomoya ngokutshintshiselana kobushushu, ngelixa ususa ukufuma kunye nomgubo ocolekileyo. Ngokuqhelekileyo ixhotyiswe ngenkqubo yokulawula ubushushu obuzenzekelayo.
* Kabini-idiski epholileyo / Amanzi{1}}igubu elipholileyo: Ezinye izixhobo zokupholisa ozikhethelayo.
4. Icandelo lokuxuba kunye nokubumba Injongo: Xuba isanti esetyenzisiweyo esetyenzisiweyo esetyenzisiweyo (enesanti entsha eyongeziweyo ngokomlinganiselo wokubuyisela ilahleko) kunye ne-resins kunye nee-agent zokunyanga ukuvelisa isanti yokubumba engasetyenziselwa ukubumba.
Izixhobo eziphambili:
* Umxube wesanti oqhubekayo: Eyona isetyenziswa kakhulu. Okufana-nesantya esiphezulu sohlobo lwerotor yomxube wesanti, enobunzima bokuxuba okuphezulu kunye nokufana, kwaye iyakwazi ukudibanisa ngokuzenzekelayo kunye nomgca wokubumba. Undoqo wayo kukulawula ngokuchanekileyo inani lokongezwa kwee-resin kunye nee-agent zokuphilisa (ngokuqhelekileyo i-0.8% -1.5% yobunzima besanti).
5. Ukugcinwa kwesanti kunye nenkqubo yokuhambisa
Injongo: Qhagamshela izitishi ezahlukeneyo kunye nevenkile yokugcina ibuffering.
Izixhobo: Imigqomo yokugcina isanti, izinyusi zebhakethi, ii-belt conveyors, iinkqubo zokuhambisa umoya, njl.
III. Iimpawu zobugcisa ezingundoqo zenkqubo yokugaywa kwentlabathi yeresin
Inkqubo enempumelelo yokurisayikilisha kufuneka ilawule ezi zalathisi zilandelayo:
Ilahleko yokutshisa i-resin (LOI): Isalathisi esiphambili sokulinganisa intsalela yezinto eziphilayo. Okona kusezantsi kokungcono,{1}}imigca yokurisayikilisha ekumgangatho ophezulu inokulawula kwi-1.5%-2.5%.
Umxholo we powder (PD): Ichaphazela ngokuthe ngqo amandla kunye nokunyanzeliswa kwesanti yokubumba. Kufuneka ilawulwe<0.5%.
Ubushushu beSanti: Kufuneka buzinze kwi-25-35 degree.
Ixabiso le-PH (lesanti ye-phenolic resin): Isanti esetyenzisiweyo kufuneka ibe ne-asidi ebuthathaka ukwenza lula ukunyanga intlaka.
Ukuhanjiswa kobungakanani besuntswana: Gcina uzinzo ukuthintela isanti ecolekileyo kakhulu okanye encinci kakhulu.
IV. Iindlela zophuhliso kunye neengcebiso zokukhetha
Ukurisayikilisha okudityanisiweyo okusebenzayo: "Impembelelo eyomeleleyo ye-centrifugal (ephambili) + impembelelo yokuhamba komoya (yesibini)" iye yaba lulungelelwaniso oluqhelekileyo, olunokufikelela kumlinganiselo ophezulu wokurisayikilisha ngelixa uqinisekisa umgangatho.
Ubukrelekrele kunye nokonga amandla: Ulawulo oluzenzekelayo oluvaliweyo{0}}lobushushu besanti, umthamo womoya, kunye nesixa sokutya; ukurisayikilishwa kwesanti eshushu (njengokusebenzisa isanti eshushu ukutshisa iiarhente zokunyanga kwangaphambili).
Ukhuseleko lokusingqongileyo olomeleziweyo: Uqokelelo oluphakathi kunye nonyango lwe-VOC yokukhupha igesi eveliswe kwindawo yokuhlamba isanti, i-recycling, kunye nezikhululo zokuxuba (ezifana nendlela yokutshisa, indlela ye-adsorption).
Iingcebiso zoKhetho: Kumasifundisane amakhulu-entsimbi kunye nentsimbi yokugalela ngemveliso yonyaka yeetoni ezingamawaka aliqela okanye ngaphezulu, indlela eyomileyo eyomileyo yokurisayikilisha + inkqubo yokulawula ubushushu bentlabathi yenkqubo yokuvelisa intlaka yentlabathi lukhetho olunoqoqosho kunye nokusingqongileyo. Inokuthi iphinde isetyenziswe kwi-95% okanye ngaphezulu kwesanti endala, kunye nokuzaliswa kwesanti entsha kufuna kuphela i-5-}10%, kwaye izibonelelo zexesha elide zibalulekile. Ngamafutshane, inkqubo yokucocwa kwentlabathi yeresin yinkqubo yobunjineli entsonkothileyo egxile "kuhlaziyo olomileyo olusebenzayo" kunye "nolawulo oluchanekileyo lobushushu besanti", ejolise ekufumaneni usetyenziso oluphezulu lwemithombo yesanti kunye{8}}nomgangatho ophezulu wokuvaleka komjikelo.
