nkhani

Pamene makampani opanga zinthu padziko lonse lapansi akuyesetsa kuti zinthu ziyende bwino, kugwiritsa ntchito bwino ndalama, komanso kupeza njira zothetsera mavuto omwe angawononge chilengedwe, kampani yodziwika bwino ya mankhwala ikusintha pang'onopang'ono mawonekedwe a makampani opanga zinthu zopangidwa ndi polyurethane.Dimethylthioterephthalic anhydride, yomwe yafupikitsidwa kuti DMTDA (nambala ya CAS: 106264-79-3), monga chosinthira kusintha kwa madzi, ikupatsa opanga ku Southeast Asia ndi North America njira ina yabwino kwambiri kuposa zipangizo zachikhalidwe pankhani ya magwiridwe antchito.

I. Kufotokozeranso Miyezo Yogwira Ntchito: Ubwino Waukulu wa DMTDA

DMTDA si njira yongolowa m'malo mwake; ndi njira yowonjezera magwiridwe antchito. Poyerekeza ndi mankhwala ochiritsira olimba a MOCA, DMTDA yapeza kupambana kwakukulu pa mawonekedwe enieni, kusavuta kugwira ntchito, komanso magwiridwe antchito omaliza.

Mafotokozedwe Ofunika Kwambiri a Ukadaulo:

Dzina la Chinthu: Dimethyl Thio-Toluene Diamine (DMTDA)
Nambala ya CAS:106264-79-3
Fomula ya Maselo:C9H14N2S2
Maonekedwe:Madzi Opepuka achikasu owonekera bwino
Chiyero:≥95% (Zonse Zomwe Zili mu Amine)
Ntchito:Chowonjezera Chain / Wothandizira Kuchiritsa / Crosslinker

Kapangidwe ka mankhwala ka DMTDA kamathandiza kuti igwire ntchito ngati cholumikizira chogwira ntchito bwino, kupereka mphamvu zapadera zamakaniko ku chinthu chomaliza cha polima. Kupangidwa kwake ndi madzi kumachotsa kufunika kotenthetsera kapena kusungunula musanagwiritse ntchito, zomwe zimafunika kwambiri pazinthu zolimba zophikira monga MOCA, potero kusunga mphamvu ndikukweza chitetezo kuntchito.

II. N’chifukwa Chiyani Muyenera Kusankha DMTDA? Kusintha Kuchokera ku MOCA

Kugwira ntchito kosavuta, magwiridwe antchito awirikiza kawiri

Madzi pa kutentha kwa chipinda: DMTDA imawoneka ngati madzi achikasu opepuka komanso okhuthala pa kutentha kwa chipinda, zomwe zimapangitsa kuti pasakhale kufunikira kwa njira yovuta yosungunula zinthu monga MOCA. Izi sizimangopulumutsa mphamvu ndi ndalama zogulira zida komanso zimathandizanso kuti ntchito yopangira zinthu ikhale yosavuta, zomwe zimapangitsa kuti ntchito yopangira zinthu ikhale yogwira mtima kwambiri.

Kukhuthala kochepa, kusakaniza kosavuta: Kukhuthala kwake kochepa kumatsimikizira kusakaniza mwachangu komanso mofanana ndi prepolymer, makamaka yoyenera njira zamakono monga kupanga jakisoni wa reaction ndi kupopera polyurea elastomers zomwe zimafuna kusakaniza bwino kwambiri.

Zachuma zabwino kwambiri, phindu lalikulu la ndalama

Mlingo wochepa: Mankhwala ofanana ndi DMTDA ndi otsika poyerekeza ndi a MOCA, zomwe zimapangitsa kuti pakhale kuchepa kwa pafupifupi 20% kwa kugwiritsa ntchito zinthu zomwe zimagwiritsidwa ntchito. Izi zikutanthauza kuti tikwaniritse magwiridwe antchito omwewo kapena abwino kwambiri pamene tikuchepetsa mwachindunji mtengo wa zinthu zopangira.

Mtengo wokhazikika: Chifukwa cha njira zopangira zokhwima komanso zotsatira zake zazikulu,Mtengo wa DMTDAikukhazikika, kupereka chitsimikizo chodalirika cha kuwongolera mtengo kwa nthawi yayitali kwa mabizinesi.

Ubwino Wabwino: Makhalidwe Abwino Kwambiri: Polyurethane elastomer yokonzedwa ndi DMTDA imagwira ntchito bwino kuposa MOCA system mu zizindikiro zazikulu monga kulimba, kukana kuwonongeka, komanso kukana kusweka. Izi zimapangitsa kuti chinthu chomaliza chikhale cholimba komanso chokhoza kupirira zovuta zina.

Zogwiritsidwa ntchito kwambiri: Kuyambira ma roller osindikizira ogwira ntchito bwino, zida zamagalimoto, mpaka zokutira zosapsa ndi moto, zipangizo zoteteza dzimbiri zachitsulo, zochitika za DMTDA zikukulirakulira nthawi zonse, zomwe zimapereka chilimbikitso champhamvu pakukweza zinthu m'mafakitale osiyanasiyana.

Yotetezeka komanso yosamalira chilengedwe, yogwirizana ndi zomwe zikuchitika padziko lonse lapansi

Kuopsa kochepa, kotetezeka: Kuopsa kwaDMTDAndi yotsika kwambiri kuposa ya MOCA, ndipo ilibe zoopsa zomwe zingayambitse khansa kapena kusintha kwa chilengedwe, zomwe zimapangitsa kuti malo opangira zinthu azigwira ntchito bwino komanso kuonetsetsa kuti ogwira ntchito ali ndi thanzi labwino, zomwe zimathandiza mabizinesi kutsatira mosavuta malamulo okhwima okhudza thanzi ndi chitetezo pantchito.

III. Njira yosamalira chilengedwe

Njira yake yopangira imagwiritsa ntchito njira yotsika mtengo komanso yosawononga chilengedwe ya "neutral distillation", mogwirizana ndi njira yapadziko lonse yopangira zinthu zobiriwira.

Kugwira Ntchito Kwambiri Kum'mwera chakum'mawa kwa Asia ndi North America: Kugunda Msika Wokongola

Ngakhale magawo a chitukuko cha misika ya Southeast Asia ndi North America ndi osiyana, onse ali ndi zofunikira mwachangu kuti pakhale njira zogwirira ntchito bwino komanso zogwira ntchito bwino.

Msika wa Southeast Asia: Kukula kwa zomangamanga ndi kupanga zinthu

Mafunde obiriwira a nyumba: Chifukwa cha kukwera kwa mizinda m'maiko akumwera chakum'mawa kwa Asia, kufunikira kwa zipangizo zomangira zogwira ntchito bwino kwawonjezeka. Kugwiritsa ntchito DMTDA m'zophimba moto ndi zitsulo zoteteza dzimbiri kumakwaniritsa bwino miyezo yapamwamba yachitetezo cha nyumba komanso kulimba komwe msikawu ukufuna.

IV. Kukweza kupanga

Monga malo ofunikira kwambiri pakusintha kwa kupanga padziko lonse lapansi, makampani opanga magalimoto, nsalu, ndi mapepala ku Southeast Asia akukula mofulumira. Kugwiritsa ntchito DMTDA m'magawo opanga zinthu zapamwamba monga zida zamagalimoto ndi makina osindikizira kungathandize mabizinesi am'deralo kukulitsa mpikisano wazinthu ndikupeza unyolo wamtengo wapatali.

Msika wa North America: Ukadaulo wamakono ndi kupanga zinthu zapamwamba

Chothandizira pa ntchito zapamwamba: Msika waku North America ndi mtsogoleri pa ukadaulo wapamwamba monga kupanga jakisoni wa reaction ndi kupopera polyurea elastomers. Monga chothandizira chabwino kwambiri chochiritsira madzi,DMTDAakhoza kugwiritsa ntchito bwino ubwino wa njira zimenezi ndikuyendetsa zatsopano zaukadaulo m'magawo monga kuwunikira magalimoto ndi zophimba zoteteza zomwe zimagwira ntchito bwino kwambiri.
