Xa kuziwa ekudaleni iinkqubo ze-epoxy eziphezulu, ukhetho lwe-arhente yokunyanga ludlala indima ebalulekileyo. Phakathi kweenketho ezahlukeneyo ezikhoyo, i-DMTDA iye yavela njenge-arhente ethembekileyo nesebenzayo yokunyanga eyaziwa ngokunyusa ukusebenza ngokubanzi kwee-epoxy resins. Nokuba ubumba izinto zokugquma kwimizi-mveliso, izinto zokuncamathelisa, okanye imathiriyeli edibeneyo, ukuqonda iziboneleloDMTDAkwii-epoxy resins zinokukunika umda wokukhuphisana.

Ukuvula ukuguquguquka okukhulu kunye nokuqina

Omnye wemingeni ephambili ekuqulunqweni kwe-epoxy kukulinganisa ubulukhuni kunye nokuqina. I-DMTDA (i-Dimethylthiotoluenediamine) inceda ukuvala lo msantsa ngokuzisa amacandelo aguquguqukayo kwinethiwekhi yepolymer. Oku bhetyebhetye kukhokelela ekuxhathiseni okuphuculweyo kunye nokuncipha kobuqhophololo, kuyenza ilungele izicelo ezifuna amandla kunye nokuqina.

Xa isetyenziswe ngokuchanekileyo, i-DMTDA kwii-epoxy resins igalelo kwiipropati ezingcono zokwandisa, ukuqinisekisa ukuba imveliso yokugqibela inokumelana noxinzelelo lomatshini ngaphandle kokuqhekeka okanye ukuchithwa.

Ukwandiswa kweThermal kunye neChemical Resistance

Ukusetyenziswa kwe-epoxy yanamhlanje kudla ngokubandakanya ukuvezwa kwindawo enzima-nokuba bubushushu, ukufuma, okanye iikhemikhali. I-DMTDA ixabiswa ngenxa yokukwazi kwayo ukuphucula ukuzinza kwe-thermal kunye nokumelana nemichiza kwiinkqubo ze-epoxy. Oku kuthetha ukuba imathiriyeli enyangwa nge-DMTDA igcina iipropathi zazo kuluhlu olubanzi lwamaqondo obushushu kunye neemeko, iqinisekisa ukuthembeka nakwizicwangciso zemizi-mveliso ezinobundlobongela.

Ngokubandakanya i-DMTDA kwii-epoxy resins, abavelisi banokuqulunqa iifomyula ezigcina ingqibelelo phantsi kwebhayisikile eshushu kunye nokuvezwa kwii-arhente ezitshabalalisayo, ezizenza zilungele ukusetyenziswa kwi-aerospace, i-electronics, kunye necandelo lezemoto.

Ubomi bembiza obude, Unyango olukhawulezayo-Ukudibanisa okuphumelelayo

Ukucubungula ukuguquguquka kubalulekile kwizicelo ze-epoxy, kwaye le yenye indawo apho i-DMTDA ikhanya khona. Inika ubomi obude bembiza kwiqondo lokushisa, ukunika abasebenzisi ixesha elininzi lokuxuba kunye nokusebenzisa ukuqulunqwa. Nangona kunjalo, emva kokuba ubushushu bufakwe, inkqubo yokunyanga ikhawuleza kakhulu, inciphisa ixesha lokunciphisa kunye nokwandisa imveliso.

Olu ncedo lubini lwenza ukuba i-DMTDA kwi-epoxy resins ibe nomtsalane ngakumbi kwimveliso yamashishini amakhulu apho ukuhamba komsebenzi okusebenzayo kunye nokusebenza okungaguqukiyo kubalulekile.

Ukuhambelana neeNkqubo zeEpoxy ezahlukeneyo

Ayizizo zonke ii-agent zokunyanga ezihambelanayo jikelele, kodwa i-DMTDA yaziwa ngokuhambelana kwayo okugqwesileyo kunye noluhlu olubanzi lwe-epoxy resins, kuquka i-bisphenol-A kunye neentlobo ze-bisphenol-F. Oku kuguquguquka kwenza abaqulunqi basebenzise i-DMTDA kuzo zonke ii-aplikeshini ezahlukeneyo ngaphandle kokuphinda kusetyenzwe kwakhona okanye uhlengahlengiso, konga zombini ixesha kunye neendleko.

Nokuba uphuhlisa uqulunqo olutsha okanye ulungisa esele ikho, ukudibanisa i-DMTDA kwiiresin ze-epoxy kunokunceda ukufezekisa iziphumo ezihambelanayo kunye nokulinga-kunye-nempazamo encinci.

Enye indlela eKhuselekileyo yeeDiamines ezinuka kamnandi

Iidayimani zesiNtu ezinevumba elimnandi zihlala ziza nempilo kunye nokuphatha iinkxalabo. I-DMTDA inika enye indlela ekhuselekileyo, enetyhefu esezantsi kunye neempawu zokuphatha ngcono, ezibaluleke ngakumbi kwiindawo zokusebenza ezigxile kukhuseleko nokuthotyelwa.

Ngokukhetha i-DMTDA kwii-epoxy resins, abavelisi abaphuculi kuphela ukusebenza kwemveliso kodwa banegalelo kwiindawo ezikhuselekileyo zokuvelisa.

Ukuqukumbela

Njengoko iimfuno zemathiriyeli eyomeleleyo, eyomelele ngakumbi, kunye nesebenzayo ngakumbi iqhubeleka nokunyuka, i-DMTDA ingqina ukuba yinxalenye yexabiso leepoxy resin formulations. Ukusuka kukuqina okuphuculweyo kunye nokumelana nobushushu ukuya ekuqhubeni ngcono kunye nokhuseleko, izibonelelo zayo zenza kube lukhetho olunobulumko kubaqulunqi abacinga phambili.

Ngaba ukulungele ukuphonononga iinkqubo ze-epoxy eziphezulu ezilungiselelwe iimfuno zakho zokusebenza? Umlingane kunyeIthamsanqakwaye uvule amandla apheleleyo etekhnoloji ye-epoxy enezisombululo ezikumgangatho ophezulu ezilungiselelwe imingeni yangomso.
