Pakati penyeredzi dzakawanda dzine makemikari, m-phenyldimethylamine, ine hunhu hwayo hwakasiyana uye hunoshamisa, yave chinhu chakakosha mumaindasitiri mazhinji, ichitungamira shanduko imwe neimwe yeindasitiri uye hunyanzvi mushure meimwe.
M-phenyldimethylamine imvura isina ruvara patembiricha yemumba, ine huremu hwemamorekuru hwe136.194, density ye1.1±0.1 g/cm³, poindi yekufashaira ye247.0±0.0 °C (760 mmHg), uye poindi yekunyunguduka ye14°C. Muchimiro chayo chemamorekuru, boka re aliphatic primary amine ne benzene ring zvakabatanidzwa zvine hungwaru, zvichizvipa hunhu hwakasiyana-siyana hunoshamisa.
"Injini yepamusoro" mumunda we epoxy curating
Semushonga we epoxy resin, m-phenyldimethylamine inotungamira muindasitiri iyi. Nekuti ine mapoka e aliphatic primary amine, inogona kukurumidza kuita mhedzisiro yekupisa patembiricha yemumba, ichipfupisa zvakanyanya kutenderera kwekugadzira uye ichivandudza kushanda zvakanaka kwekugadzira. Chigadzirwa chakagadziriswa hachingori chete nekudzivirira kupisa kwakanaka uye chinogona kuramba chakasimba munzvimbo dzinopisa zvakanyanya, izvo zviri nani pane common aliphatic polyamines; Chinewo makemikari anodzivirira zvakanyanya. Ingave organic solvents senge toluene kana corrosive media senge 10% wt sulfuric acid, zvakaoma kukonzera kukuvara kwayo. Iyi ficha yakaigonesa kupenya zvakajeka munzvimbo dzemabhatiri sealing adhesives uye terminal post adhesives. Nekubatsira kwe low viscosity, nyore kuyerera uye kupinda zvakanaka, inoita kuti adhesive ikwanise kuvharwa zvakakwana, ichidzivirira kupera kweacid gas uye acid liquid, uye ichitsungirira simba rekunze, nokudaro ichichengetedza kushanda kwakachengeteka uye kwakasimba kwemabhatiri. Zvichakadaro, mukushandisa machira ekudzivirira ngura pakugadzirisa mabhiriji, mapaipi, midziyo yengarava, pasi, nezvimwewo, m-phenylenediamine, pamwe chete ne epoxy resin, inogona kuratidza kunamira kwakanaka kunyangwe munzvimbo dzine hunyoro, ichidzivirira mamiriro akaomarara uye ichiwedzera hupenyu hwebasa rezvivakwa.
"Innovation Booster" yemaindasitiri akasiyana-siyana
Mukugadzirwa kwema polyurethane resins uye machira ekudzivirira, m-phenyldimethylamine inoshanda sechinhu chakakosha uye inobatsira mukuvaka mamorekuru anoshanda zvakanyanya. Inogona kuwedzera zvakanyanya kuchinjika, kuramba kupfeka uye kuramba kukanganiswa kwezvinhu zve polyurethane, ichipa machira ekudzivirira mamiriro ekunze uye kupenya kwakanyanya. Inoshandiswa zvakanyanya mukushongedza pamusoro nekudzivirira fenicha, mota, kuvaka nedzimwe nzvimbo. Mumunda wekuwedzera rabha, kuwedzerwa kwayo kunogona kugadzirisa maitiro e vulcanization yerabha, kuwedzera simba, kusimba uye kuramba kukwegura kwezvigadzirwa zverabha, uye kuvandudza zvakakwana mhando yezvigadzirwa zverabha kubva kumatayi kusvika kumachira ekudzivirira rabha. Pamusoro pezvo, m-phenyldimethylamine zvakare monomer yakakosha yekugadzira zvinhu zve nylon zvinoshanda zvakanyanya senge polyadipylm-phenyldimethylamine (MXD6). MXD6, ine chimiro chayo chakasiyana chakapihwa ne m-phenyldimethylamine, ine hunhu hwakakura hwekudzivirira (oxygen permeability i1/10 chete yePA6), simba rakawanda uye kuomarara (simba rekudhonza kusvika 280MPa, flexural modulus kusvika 24GPa), inodzivirira kupisa zvakanaka (kupisa kupisa kusvika 73.8℃, 1.8MPa), uye mwero wakaderera wekunyudzwa kwemvura. Yakaratidza kugona kukuru kwekushandisa muminda yemazuva ano senge zvinhu zvidiki zvemarobhoti, zvikamu zvemotokari itsva dzesimba, uye kurongedza chikafu kwepamusoro-soro, uye yave chinhu chikuru chinosimudzira kuvandudzwa kwemaindasitiri. Kwete izvozvo chete, mumaindasitiri mazhinji akadai semapurasitiki anonzwa chiedza, mishonga yezvipembenene, fiber finishing agents, ngura inhibitors, chelating agents, mafuta ekugadzira, uye paper processing, m-phenyldimethylamine, ine hunhu hwayo hwakasiyana, inopa simba rinoramba riripo rekusimudzira chigadzirwa uye kugadzirisa mashandiro.
Kubva pakugadzirwa kusvika pakushandiswa kwekupedzisira, m-phenyldimethylamine inotevedzera zvakanyanya kudzorwa kwemhando. Maitiro ekugadzira anoshandisa tekinoroji yepamusoro, kutanga kubva pamusanganiswa we m-xylene ne p-xylene, uye wobva waita oxidation reactions nemhepo neammonia kuti igadzire m-xylene ne p-phenyldimethylnitrile. Mushure mezvo, inotevedza matanho akatevedzana akadai sekusuka mumvura, kuomesa, uye catalytic hydrogenation, pakupedzisira ichiwana zvigadzirwa zvine hutsanana hwakawanda. Boka rega rega rezvigadzirwa rinoedzwa zvakasimba kuti rive nechokwadi chekuti kuchena kwe ≥ 99.0%, nezviratidzo zvese zvakagadzikana uye zvakavimbika, zvichipa vatengi sarudzo inonyaradza. Chigadzirwa ichi chakaputirwa mumadhiramu epurasitiki e200-kilogram kuti chitakurwe uye chichengetwe zviri nyore. Chinofanira kuchengetwa munzvimbo inotonhorera uye ine mhepo yakanaka, ichitevedzera mitemo yekuchengetedza nekutakura zvinhu zvinobvira uye zvine chepfu kuitira kuti mhando yechigadzirwa isakanganiswe.
M-phenyldimethylamine, ine mashandiro ayo akanaka sehwaro uye mashandisirwo akasiyana-siyana semapapiro, iri kubatsira maindasitiri akasiyana-siyana kupinda mumatambudziko ehunyanzvi uye kutanga rwendo rutsva rwemhando yepamusoro uye kufambira mberi kwehunyanzvi. Batanai nem-phenyldimethylamine uye gamuchirai remangwana risingaperi reindasitiri yemakemikari pamwe chete!
