Kudzora Kuwanda kweEthylene muKugadzirwa kweRabha
Rabha yakagadzirwa nevanhu irabha inogadzirwa nezvinhu zvinobva mumafuta. Inowanzo shandiswa mumabasa akadai sematayi, magonhi nemahwindo. Kubvisa rabha isina kugadzirwa kunosanganisira kunatsa zvikamu zvemafuta aya—kuburikidza nemaitiro akadai sekuputika kwenaphtha uye kunyungudutsa—kuchenesa mamonomer aya, sezvo zvinhu zvinosvibisa zvinogona kukanganisa polymerization reaction inotevera. Mamonomer akacheneswa anowanzova nekuchena kwe99.5% kana kupfuura, zvichiisa hwaro hwekugadzirwa kwerabha.
Danho guru rekugadzira polymerization: mamonomer akacheneswa anosanganiswa nemainitiators uye anogona kuparadzirwa mumvura kana kunyungudutswa mu organic solvents. Maitiro aya anoshandura mamonomer madiki kuita macheni marefu epolymer, zvichiburitsa rabha isina kuchena ine rabha hydrocarbon ye80–90%. Danho rakakosha rekutevera vulcanization, uko sarufa kana peroxides zvinowedzerwa uye zvinopiswa kuti zvigadzire cross-links pakati pemacheni epolymer - rabha isina kuvhungudutswa inonyorova uye inonamira zvekuti haishande. Rabha yakavhungudutswa pakutanga ine polymer purity ye95–98%, asi pamashandisirwo epamusoro-soro, kucheneswa kwakawedzerwa kunodiwa.
Kuoma pakuyera kuzara kweEthylene
Mukugadzirwa kwerabha, kunyanya ye ethylene-propylene-diene monomer (EPDM) kana ethylene-propylene rabha (EPR/EPM), kuyera kwakanyatsojeka kwehuwandu hwe ethylene kwakakosha pakudzora kinetics ye polymerization, kuve nechokwadi chekuti polymer properties dzakafanana uye kuderedza marara.
Pfupiso yeRubber Synthesis Process
Kugadzirwa kwerabha kweEPDM/EPR kunowanzo sanganisira:
Kutumirwa KwezvikafuEthylene nepropylene (uye diene yeEPDM) zvinoiswa semagasi mureactor, zvinowanzonyungudutswa mu solvent kana kuchengetwa muzvikamu zvegasi/mvura.
Chinogadzirisa Polymerization: CSTR kana kuti loop reactor apo mamonomers anoita nemacatalysts pa30-90°C uye 10-30 bar, zvichiita cheni dzepolymer.
Kudzoreredza Soluvhenti/Monomer: Mamonomer asina kugadziriswa anobviswa, anodzokororwazve, kana kucheneswa, kazhinji kuburikidza nekuparadzwa kana madhiramu emoto.
Kupedzisa: Polymer inoparadzaniswa, inogezwa, uye inoburitswa, nekutarisa hunhu hwesimbi uye hunyoro hwaMooney.
Ethylene inoshanda se monomer yakakosha mukugadzirwa kwerabha, chinhu chakakosha muindasitiri ye petrochemical. Kuwanda kwe monomer iyi mukati memudziyo we reaction kunotungamira zvakananga kinetics ye polymerization uye, nekudaro, hunhu hwepanyama uye hwemakemikari hwe polymer yekupedzisira, senge huremu hwemamorekuru uye tembiricha yekunyunguduka. Kana huwandu hwe ethylene husina kudzorwa nemazvo, polymer inobuda inogona kuratidza polydispersity isingadzoreki, zvichitungamira mukupararira kwakakura kwehuremu hwemamorekuru uye kusagadzikana kwemhando yekupedzisira yechigadzirwa. Semuenzaniso, hukama huripo pakati pekuwedzera kwe ethylene pressure uye ethylene content mu copolymers inogadzirwa, izvo zvinokanganisa tembiricha yavo yekunyunguduka.
Kuchinja uku kwemhando yechigadzirwa kune mhedzisiro yakananga uye inobatika mune zvemari. Kuti ive nechokwadi chekuti boka rega rega rinogadzirwa rinosangana nezvinodiwa zvemhando yepamusoro, vashandi vanowanzo tevedzera nzira inozivikanwa se "kupihwa kwemhando yepamusoro". Izvi zvinosanganisira kugadzira chigadzirwa chine hunhu hwemhando yepamusoro hunopfuura zvinodiwa, zvichikonzera kushanduka kwemaitiro acho zvakanyanya kuti zvikwanisike kuyera nekudzora. Maitiro aya, kunyangwe achivimbisa kugamuchirwa kwechigadzirwa, anotungamira zvakananga pakuwedzera kwekushandiswa kwezvinhu zvakabikwa, kushandiswa kwesimba rakawanda, uye nguva yakareba yekutenderera, zvese izvi zvinoshandura mumitengo mikuru yekushanda uye kudzikira kwepurofiti. Chinhu chikuru chedambudziko iri hachisi chikanganiso mumaitiro emakemikari pachawo, asi kushomeka mukuyerwa kwenguva chaiyo uye kudzorwa kwerobhoti kunochitonga, zvichitungamira kune reactive pane kwete proactive mode yekushanda.
Taura nenyanzvi yedu kuti iongorore zvinodiwa pakushanda kwako.
Mhinduro Yekuyera Kuwanda kweLonnmeter Inoenderera Mberi
Ongororo yechinyakare yakavakirwa pakurabhoritari isina kunyorwa haina kukodzera zvinodiwa zvinogara zvichienderera mberi zvemuchina wemazuva ano wekugadzira. Kazhinji inokonzera kunonoka kwekuongorora uye kuyera kwakawanda kwevashandi. Nemamwe mashoko, data rinogashirwa nevashandisi ipfupiso yemaitiro kubva mumaminitsi kana kunyange maawa. Kushomeka kweruzivo kunokonzera kutsauka kwemhando mushure mekunge zvatoitika uye pamwe mushure mekunge batch yese yakanganiswa, zvichikonzera kurasika kunodhura uye kugadziriswa patsva.
Lonnmeter yakagadzira mainjiniyakuwanda kwe sensor ye ethylenekuti iite kuyerwa kwakarurama kwekuyera panguva chaiyo mukuita kwemakemikari kunoenderera mberi. Inoshanda zvakanaka kunyangwe munzvimbo inochinja nekukurumidza; Online ethylene concentration meter chishandiso cheindasitiri chakagadzirirwa kugadzirisa zvinodiwa zvekuyera kwakarurama kwemaitiro emakemikari. Inoshandisa matekinoroji epamusoro ekuona -- sosi yeacoustic signal yekumutsa forogo yesimbi, zvichiita kuti forogo idengenyeke nefrequency yayo yechisikigo ye resonant. Zvinonyanya kukosha, iyi resonant frequency inoratidza hukama hwakananga nehuwandu hwemvura iyo tuning fork inosangana nayo. Zvadaro, huwandu hwemvura hunogona kuonekwa kuburikidza nekuongorora frequency - ne tembiricha inogadziriswa kudzivirira tembiricha inoyerera mukati me system, zvichiita kuti kuyerwa kuve kwakarurama.
Kugadzira Fork Maumbirwo
Kuiswa Kwekuisa MuRubber Synthesis Process
-
Mutsetse weKupa Monomer: Isa sensor mu ethylene feed pipeline post-compressor kuti uve nechokwadi chekuchena uye kugadzirisa dosing.
Mukana weReactor: Isa panzvimbo yekusanganisa monomer-solvent nehexane/propylene kudzora ethylene yakanyungudutswa.
Mu-Reactor: Nzvimbo mukati meCSTR pedyo neagitator yekudzora polymerization panguva chaiyo.
Mutsetse weKudzokorodza: Tsvaga panzvimbo inoburitswa dhiramu kuti ugadzirise kudzoreredzwa kwe ethylene isina kubatwa.
Mutsetse weKufefetera: Isa mumutsara wekubvisa/kuburitsa mhepo kuti utarise kuburitswa kwemhepo uye uve nechokwadi chekuti yakachengeteka.
