izindaba

Njengoba imboni yokukhiqiza yomhlaba wonke ilwela ukusebenza okuphezulu, ukusebenza kahle kwezindleko, kanye nezixazululo ezinobungani nemvelo, isazi samakhemikhali esiyinhloko sishintsha buthule isimo semboni ye-polyurethane.I-anhydride ye-Dimethylthioterephthalic, efushaniswe ngokuthi i-DMTDA (inombolo ye-CAS: 106264-79-3), njenge-ejenti yokwelapha uketshezi eguquguqukayo, inikeza abakhiqizi eNingizimu-mpumalanga ye-Asia naseNyakatho Melika enye indlela efanelekile edlula izinto zendabuko ngokusebenza.

I. Ukuchaza Kabusha Izindinganiso Zokusebenza: Izinzuzo Eziyinhloko ze-DMTDA

I-DMTDA ayiyona nje into ethatha indawo; iyisisombululo esithuthukisiwe sokusebenza. Uma iqhathaniswa ne-MOCA yendabuko yokwelapha eqinile, i-DMTDA ifinyelele ukuphakama okuphelele ngesimo somzimba, ukulula kokusebenza, kanye nokusebenza komkhiqizo wokugcina.

Imininingwane Yobuchwepheshe Ebalulekile:

Igama Lomkhiqizo: I-Dimethyl Thio-Toluene Diamine (DMTDA)
Inombolo ye-CAS:106264-79-3
Ifomula Yamamolekyuli:C9H14N2S2
Ukubukeka:Uketshezi Oluphuzi Olukhanyayo Olubonakalayo
Ubumsulwa:≥95% (Okuqukethwe Okuphelele kwe-Amine)
Umsebenzi:I-Chain Extender / I-ejenti Yokwelapha / I-Crosslinker

Isakhiwo samakhemikhali se-DMTDA siyivumela ukuthi isebenze njenge-crosslinker ephumelelayo, ihlinzeka ngezakhiwo ezihlukile zemishini kumkhiqizo wokugcina we-polymer. Uhlobo lwayo loketshezi luqeda isidingo sokushisa noma ukuncibilikisa ngaphambi kokusetshenziswa, okuyisidingo esivamile sama-ejenti okwelapha aqinile njenge-MOCA, ngaleyo ndlela kongiwe amandla futhi kuthuthukiswe ukuphepha emsebenzini.

II. Kungani Kufanele Ukhethe i-DMTDA? Ukushintsha kusuka ku-MOCA

Ukusebenza okulula, ukusebenza kahle kabili

Uketshezi ekamelweni lokushisa: I-DMTDA ibonakala njengoketshezi oluphuzi olucwebezelayo ekamelweni lokushisa, okususa isidingo senqubo yokuncibilikisa enzima njenge-MOCA. Lokhu akugcini nje ngokusindisa amandla kanye nokutshalwa kwezimali kwemishini kodwa futhi kwenza inqubo yokukhiqiza ibe lula, okuthuthukisa kakhulu ukusebenza kahle kokukhiqiza.

Ukuchachamba okuphansi, ukuxuba okulula: Ukuchachamba kwayo okuphansi kuqinisekisa ukuxubana okusheshayo nokulinganayo ne-prepolymer, okufanelekela kakhulu izinqubo ezithuthukisiwe ezifana nokubumba umjovo wokusabela kanye nokufutha ama-elastomer e-polyurea adinga ukusebenza kahle kokuxuba.

Umnotho omuhle kakhulu, inzuzo enkulu yezindleko

Isilinganiso Esiphansi: Isilinganiso samakhemikhali se-DMTDA siphansi kunese-MOCA, okuvumela ukwehla cishe okungu-20% ekusetshenzisweni kwezinto ezibonakalayo ezisetshenziswayo. Lokhu kusho ukufeza ukusebenza okufanayo noma okungcono kakhulu ngenkathi kunciphisa ngqo izindleko zezinto zokusetshenziswa.

Intengo ezinzile: Ngenxa yezinqubo zokukhiqiza ezivuthiwe kanye nemiphumela yesikali,intengo ye-DMTDAihlala izinzile, inikeza isiqinisekiso esithembekile sokulawulwa kwezindleko zesikhathi eside kwamabhizinisi.

Ikhwalithi ethuthukisiwe: Izakhiwo zomzimba ezinhle kakhulu: I-polyurethane elastomer elashwe nge-DMTDA idlula uhlelo lwe-MOCA ngezinkomba ezibalulekile njengokuqina, ukumelana nokuguguleka, kanye nokumelana nokuqhekeka kwe-flex. Lokhu kwenza umkhiqizo wokugcina uhlale isikhathi eside futhi ukwazi ukumelana nezimo ezidinga kakhulu.

Kusebenza kabanzi: Kusukela kuma-roller okunyathelisa asebenza kahle kakhulu, izingxenye zezimoto, kuya ekumbozweni okungashi, izinto zensimbi ezilwa nokugqwala, izimo zokusetshenziswa kwe-DMTDA ziyaqhubeka nokukhula, zinikeza ugqozi oluqinile lokuthuthukiswa komkhiqizo ezimbonini ezahlukahlukene.

Kuphephile futhi kunobungani nemvelo, kuhambisana nezitayela zomhlaba wonke

Ubuthi obuphansi, kuphephile: Ubuthi beI-DMTDAiphansi kakhulu kuneye-MOCA, futhi ayinazo izingozi ezibangela umdlavuza noma ukuguqulwa kwezakhi zofuzo, okuthuthukisa kakhulu indawo yokukhiqiza nokuqinisekisa impilo yabaqhubi, okwenza amabhizinisi akwazi ukulandela kalula imithethonqubo yezempilo nokuphepha emsebenzini eqinile.

III. Inqubo enobungani nemvelo

Inqubo yayo yokukhiqiza isebenzisa indlela "yokuhluza engathathi hlangothi" engabizi kakhulu futhi enobungani nemvelo, evumelana nomkhuba womhlaba wonke wokukhiqiza okuluhlaza.

Ukuzibandakanya Ngokujulile eNingizimu-mpumalanga ye-Asia naseNyakatho Melika: Ukuqonda Imakethe Ephakeme

Nakuba izigaba zokuthuthuka kwezimakethe zaseNingizimu-mpumalanga ye-Asia naseNyakatho Melika zihlukile, zombili zinezidingo eziphuthumayo zezixazululo zezinto ezisebenza kahle kakhulu nezisebenza kahle kakhulu.

Imakethe yaseNingizimu-mpumalanga ye-Asia: Ingqalasizinda kanye nokwanda kokukhiqiza

Igagasi lesakhiwo esiluhlaza: Ngokusheshisa kokukhula kwedolobha emazweni aseNingizimu-mpumalanga ye-Asia, isidingo sezinto zokwakha ezisebenza kahle sikhuphuke kakhulu. Ukusetshenziswa kwe-DMTDA ezimbozweni ezingashisi umlilo kanye nezinkambu zensimbi zokulwa nokugqwala kuhlangabezana kahle nezindinganiso eziphakeme zokuphepha kwesakhiwo nokuqina okudingekayo kule makethe.

IV. Ukuthuthukiswa kokukhiqiza

Njengesisekelo esibalulekile sokudluliselwa kokukhiqiza emhlabeni jikelele, izimboni zezimoto, izindwangu, kanye nephepha zaseNingizimu-mpumalanga ye-Asia zithuthuka ngokushesha. Ukusetshenziswa kwe-DMTDA emikhakheni yokukhiqiza ephezulu njengezingxenye zezimoto kanye nama-roller okunyathelisa kungasiza amabhizinisi endawo ukuthuthukisa ukuncintisana komkhiqizo futhi abambe uchungechunge lwenani eliphezulu.

Imakethe yaseNyakatho Melika: Ubuchwepheshe obusha kanye nokukhiqiza okuphezulu

I-Catalyst yezinqubo ezithuthukisiwe: Imakethe yaseNyakatho Melika ingumholi kwezobuchwepheshe obuthuthukisiwe njengokwakheka kwe-reaction injection kanye nokufutha ama-polyurea elastomers. Njenge-ejenti efanelekile yokwelapha uketshezi,I-DMTDAingakwazi ukusebenzisa ngokugcwele izinzuzo zalezi zinqubo futhi iqhube ukusungulwa kobuchwepheshe ezindaweni ezifana nokukhanyisa izimoto kanye nezingubo zokuvikela ezisebenza kahle kakhulu.
