Mu kirere cyuzuye inyenyeri z’ibikoresho fatizo bya shimi, m-phenyldimethylamine, ifite imiterere yayo idasanzwe kandi itangaje, yabaye ikintu cy’ingenzi mu nganda nyinshi, iyobora impinduka mu nganda no guhanga udushya.
M-phenyldimethylamine ni amazi atagira ibara ku bushyuhe bw'icyumba, afite uburemere bwa molekile 136.194, ubucucike bwa 1.1±0.1 g/cm³, ubushyuhe bushyuha bwa 247.0±0.0 °C (760 mmHg), n'ubushyuhe bushongesha bwa 14°C. Mu miterere yayo ya molekile, itsinda rya aliphatic primary amine na benzene ring bihujwe mu buryo bw'ubuhanga, biha urukurikirane rw'ibintu bitangaje.
"Super Moteri" mu bijyanye no gukaraba epoxy
Nk'umuti uvura epoxy resin, m-phenyldimethylamine ni inzobere mu nganda. Kubera ko irimo amatsinda y'amine y'ibanze ya aliphatic, ishobora kugira ingaruka zo kuvura vuba mu bushyuhe bw'icyumba, ikagabanya cyane uruziga rw'umusaruro no kongera imikorere myiza. Umuti uvuwe ntugira gusa ubushyuhe bwiza kandi ushobora kuguma mu buryo buhamye mu bidukikije birimo ubushyuhe bwinshi, ibyo bikaba biruta polyamine zisanzwe za aliphatic; kandi ufite ubudahangarwa butangaje bwa chimique. Byaba ari ibintu bisukura ibinyabuzima nka toluene cyangwa ibyuma bihumanya nka aside sulfuric ya 10% wt, biragoye kuyitera kwangiza. Iyi miterere yatumye irabagirana cyane mu bijyanye n'imiti ifunga bateri n'imiti ifunga bateri. Ifite ibyiza byo kuba ifite ubukana buke, itemba neza kandi ikagira ubushobozi bwo kwinjira neza, ituma kole ishobora gufungwa neza, ikarwanya kwangirika kwa gaze ya aside na aside liquid, kandi ikihanganira ingaruka z'ingufu zo hanze, bityo ikaba irinda imikorere myiza kandi ihamye ya bateri. Hagati aho, mu gukoresha irangi rirwanya ingese mu gusana ibiraro, gusiga imiyoboro y'amazi, ibikoresho by'ubwato, hasi, nibindi, m-phenylenediamine, hamwe na epoxy resin, ishobora kugaragaza ko ifata neza ndetse no mu bidukikije bikonje, ikarwanya ikirere kibi kandi ikamara igihe kirekire mu nyubako.
"Innovation Booster" ku nganda zitandukanye
Mu gukora resins na coatings bya polyurethane, m-phenyldimethylamine ikora nk'ibikoresho by'ingenzi kandi igira uruhare mu kubaka inyubako za molekile zikora neza. Ishobora kongera cyane ubushobozi bwo koroha, kudashira no kudakora neza kw'ibikoresho bya polyurethane, igaha coatings ubushobozi bwo guhangana n'ikirere n'ubushyuhe. Ikoreshwa cyane mu gushariza no kurinda ubuso bw'ibikoresho byo mu nzu, imodoka, ubwubatsi n'ibindi. Mu rwego rw'inyongeramusaruro za rubber, kongeramo bishobora kunoza inzira yo gukurura rubber, kongera imbaraga, uburimbane no kudasaza kw'ibicuruzwa bya rubber, no kunoza cyane ubwiza bw'ibicuruzwa bya rubber kuva ku mapine kugeza ku byuma bifunga rubber. Byongeye kandi, m-phenyldimethylamine nayo ni monomer y'ingenzi mu gukora ibikoresho bya nylon bikora neza nka polyadipylm-phenyldimethylamine (MXD6). MXD6, ifite imiterere yayo yihariye ikomoka kuri m-phenyldimethylamine, ifite imiterere ikomeye y’uburinzi (umwuka wa ogisijeni ugera kuri 1/10 cya PA6), ifite imbaraga nyinshi kandi irakomeye (imbaraga zo gukurura kugeza kuri 280MPa, modulus yo kuzunguruka kugeza kuri 24GPa), irwanya ubushyuhe neza (ubushyuhe bwo guhindura ubushyuhe kugeza kuri 73.8℃, 1.8MPa), kandi ifite umuvuduko muto wo kwinjiza amazi. Yagaragaje ubushobozi bukomeye bwo kuyikoresha mu nzego zigezweho nko mu bikoresho byoroshye bya robots, ibice by’imodoka nshya zikoresha ingufu, no mu gupakira ibiribwa byo mu rwego rwo hejuru, kandi yabaye imbaraga nyamukuru zituma inganda zivugurura. Si ibyo gusa, mu nganda nyinshi nka pulasitiki ishobora gufotora, imiti yica udukoko, fibre finisher, igabanya ingese, igabanya ubushyuhe, amavuta, no gutunganya impapuro, m-phenyldimethylamine, ifite imiterere yihariye, itanga imbaraga zihoraho zo guhanga udushya no kunoza imikorere.
Kuva aho umusaruro uva kugeza ku ikoreshwa rya nyuma, m-phenyldimethylamine ikurikiza cyane igenzura ry’ubuziranenge. Inzira yo gukora ikoresha ikoranabuhanga rigezweho, rihera ku ruvange rwa m-xylene na p-xylene, hanyuma igakora oxidation hamwe n’umwuka na ammonia kugira ngo ikore m-xylene na p-phenyldimethylnitrile. Nyuma yaho, inyura mu ntambwe zisobanutse nko koza amazi, kumisha, no gukamura hydrogenation, amaherezo ikabona ibicuruzwa bifite isuku nyinshi. Buri gice cy’ibicuruzwa gikorerwa isuzuma rikomeye kugira ngo harebwe ko bifite isuku ya ≥ 99.0%, hamwe n’ibimenyetso byose bihamye kandi byizewe, bigaha abakiriya amahitamo meza. Ibicuruzwa bipfunyitse mu tugoma twa pulasitiki twa kilogarama 200 kugira ngo byorohere kubitwara no kubibika. Bigomba kubikwa ahantu hakonje kandi hahumeka neza, bubahiriza cyane amabwiriza yo kubika no gutwara ibintu bishobora gushya n’uburozi kugira ngo ubwiza bw’ibicuruzwa butagira ingaruka.
M-phenyldimethylamine, ifite imikorere myiza nk'ishingiro n'ikoreshwa ritandukanye nk'amababa, irimo gufasha inganda zitandukanye guca mu mbogamizi za tekiniki no gutangira urugendo rushya rw'iterambere ry'ubuziranenge n'udushya twinshi. Fatanya na m-phenyldimethylamine kandi wifatanye mu guhaza ahazaza h'inganda zikora imiti!
