iindaba

Njengoko ishishini lemveliso lehlabathi lizama ukusebenza okuphezulu, ukusebenza kakuhle kweendleko, kunye nezisombululo ezinobuhlobo nokusingqongileyo, icandelo eliphambili leekhemikhali liyila ngokutsha ngokuzolileyo imeko-bume yeshishini le-polyurethane.I-anhydride ye-Dimethylthioterephthalic, efinyeziweyo njenge-DMTDA (inombolo ye-CAS: 106264-79-3), njengearhente yokuguqula ulwelo, inika abavelisi kuMzantsi-mpuma we-Asia nakuMntla Melika enye indlela efanelekileyo edlula izixhobo zemveli ngokubhekiselele ekusebenzeni.

I. Ukuchaza ngokutsha iMigangatho yokuSebenza: Iingenelo eziphambili ze-DMTDA

I-DMTDA ayisiyonto ithatha indawo nje kuphela; sisisombululo esiphuculweyo sokusebenza. Xa ithelekiswa ne-MOCA yesiqhelo yokulungisa izinto eziqinileyo, i-DMTDA ifikelele kwinqanaba eliphezulu kwimo yomzimba, ukusebenziseka lula, kunye nokusebenza kwemveliso yokugqibela.

Iinkcukacha zoBugcisa eziPhambili:

Igama lemveliso: I-Dimethyl Thio-Toluene Diamine (DMTDA)
Inombolo ye-CAS:106264-79-3
Ifomula yeMolekyuli:C9H14N2S2
Inkangeleko:Ulwelo oluMthubi oMhlophe ocacileyo
Ubunyulu:≥95% (Umxholo we-Amine iyonke)
Umsebenzi:I-Chain Extender / I-Agent yoNyango / i-Crosslinker

Ulwakhiwo lweekhemikhali lwe-DMTDA luyivumela ukuba isebenze njenge-crosslinker esebenzayo, inika iipropati ezibalaseleyo zoomatshini kwimveliso yokugqibela ye-polymer. Uhlobo lwayo lolwelo lususa isidingo sokufudumeza okanye sokunyibilikisa ngaphambi kokusetyenziswa, imfuneko eqhelekileyo kwiiarhente eziqinileyo ezifana ne-MOCA, ngaloo ndlela igcina amandla kwaye iphucula ukhuseleko kwindawo yokusebenza.

II. Kutheni Ukhetha i-DMTDA? Utshintsho oluvela kwi-MOCA

Ukusebenza okulula, ukusebenza kakuhle kuphindwe kabini

Ulwelo kubushushu begumbi: I-DMTDA ibonakala njengolwelo olutyheli olukhanyayo noluthambileyo kubushushu begumbi, isusa imfuneko yenkqubo yokunyibilika enzima njenge-MOCA. Oku akugcini nje ngokusindisa utyalo-mali lwamandla kunye nezixhobo kodwa kukwalula inkqubo yemveliso, nto leyo ephucula kakhulu ukusebenza kakuhle kwemveliso.

Ukuxuba okuncinci, okulula: Ukuxuba okuncinci kuqinisekisa ukuxubana okukhawulezayo nokulinganayo ne-prepolymer, ngakumbi ezifanelekileyo kwiinkqubo eziphambili ezifana nokubumba i-reaction injection kunye nokutshiza i-polyurea elastomers ezifuna ukusebenza kakuhle kokuxuba.

Uqoqosho oluhle kakhulu, inzuzo enkulu yeendleko

Idosi ephantsi: I-chemical equivalent ye-DMTDA iphantsi kune-MOCA, nto leyo evumela ukuncipha malunga ne-20% kokusetyenziswa kwezinto ezibonakalayo. Oku kuthetha ukufikelela ekusebenzeni okufanayo okanye okungcono ngakumbi ngelixa kunciphisa ngokuthe ngqo iindleko zezinto eziluhlaza.

Ixabiso elizinzileyo: Ngenxa yeenkqubo zemveliso ezivuthiweyo kunye nemiphumo yesikali,ixabiso le-DMTDAihlala izinzile, inika isiqinisekiso esithembekileyo sokulawula iindleko zexesha elide kumashishini.

Umgangatho ophuculweyo: Iipropati zomzimba ezibalaseleyo: I-polyurethane elastomer enyangiweyo nge-DMTDA idlula inkqubo ye-MOCA kwiimpawu eziphambili ezifana nokuqina, ukumelana nokuguguleka, kunye nokumelana nokuqhekeka kwe-flex. Oku kwenza imveliso yokugqibela ihlale ixesha elide kwaye ikwazi ukumelana neemeko ezinzima ngakumbi.

Isebenza ngokubanzi: Ukususela kwiirola zokuprinta ezisebenza kakuhle, iindawo zeemoto, ukuya kwiingubo ezingatshiyo, izixhobo zesinyithi ezichasene nokugqwala, iimeko zokusetyenziswa kwe-DMTDA zikhula rhoqo, zibonelela ngenkuthazo enamandla yokuphucula iimveliso kumashishini ahlukeneyo.

Ikhuselekile kwaye inobuhlobo nokusingqongileyo, ihambelana neemeko zehlabathi

Ubuthi obuphantsi, obukhuselekileyo: Ubuthi beI-DMTDAiphantsi kakhulu kune-MOCA, kwaye ayinazo iingozi ezinokubangela umhlaza okanye utshintsho emzimbeni, nto leyo ephucula kakhulu imeko yemveliso kwaye iqinisekisa impilo yabaqhubi, nto leyo evumela amashishini ukuba alandele ngokulula imigaqo engqongqo yempilo nokhuseleko emsebenzini.

III. Inkqubo enobuhlobo nokusingqongileyo

Inkqubo yayo yemveliso isebenzisa indlela "yokucoca engathathi cala" engabizi kakhulu nenobuhlobo nokusingqongileyo, ihambelana nomkhwa wehlabathi wokuvelisa izinto eziluhlaza.
