Global - Premier TDI: The Indispensable Building Block in Polyurethane Industry

Kite ma nen ku piny man kemikol

Nen man nguce: TDI nyuthire calu piny ma rangi pare nen ungo nyo ma nya nya nya, pii ma wango wang matek. Ewodho nguc ma tek, matek, man ma nyayu anyonga, ma tiyo calu lanyuth ma pire tek mi bedo tiye.
Solubility man Reactivity: Ecopu bedu yot ni rubu ku kit piny matung tung macalo ethanol (ku nyai), diethylene glycol monoethyl ether, diethyl ether, acetone, carbon tetrachloride, benzene, chlorobenzene, kerosene, man olive oil. acel ikin kit pa kemikol pare ma pire tek utiye bedo pare ku pii, timo pare ma nyayu yamo ma julwongo ni carbon dioxide. Mi medo, TDI copo timo tic nyathotho ku piny ma tingo hydrogen atoms ma tiyo, piny ma jutiyo kudu i tic madwong.
Piny ma pire tek: TDI utiye ku kabedo mi lyethu ma romo 247°C, ma nyutho lyethu ma eloko kud i piny ma pii ni piny ma lyeth i the tegu pa yamu. Kabedo pare mi lyel ucaku 19.5 ku 21.5°C, ma nyutho lyethu ma piny ma edoko tek. Kabedo pa TDI utiye 127°C, ma nyutho nya i lyethu eni, ecopu wodhu lyethu ma wango mac kani piny moko ma nyayu mac utiye. Ku pek pa 1.217, epek uloyu pii, ma etiye ku adwogi ikum tic kude man poko pare ikind tic man kabedu.

Kabedo mi tic

Polyurethane Foam Production: TDI ubedo piny ma pire tek iyubu pa polyurethane foams, ma jutiyo kudu lee i kabedo mapol. I thenge mi furniture, polyurethane foams mayom ma juyubu ku TDI ubedo piny ma juyero pi yubu kom maber man maber i sofa, kom, man kabutu. I tic mi yiku mutukari, foams eni jutiyu kudu i kom mutukari, miyo bedo maber man bedo maber pi jwigo ret ikare mi ringo mutukari. Mi medo, TDI - based polyurethane foams jutiyo kudu pi gwoko lyethu, calu i friji man piny mi gwoko lyethu, pi bedo migi maber mi gwoko lyethu.
Coatings man Adhesives: TDI timo tic ma pire tek i yubu piny ma tiyo maber man ma mako piny. I tic mi ketho rangi, TDI - polyurethanes jutiyu kudu pi yubu rangi ma rii, ma rwinyo ngo, man ma rwinyo ku kemikol pi piny matung tung, ikinde utiye cuma, plastik, man yen. Coatings eni jutiyu kudu pi yiku mutukari, coatings mi wi ot, man coatings mi jam tic. I soko mi adhesives, TDI - ma tye ku adhesives juyike pi kero migi mi mako piny. Gitiyo kudu pi ketho kombe, mako piny mi mutukari, man i tic mi gedo pi mako piny matung tung mi gedo.
Yubu Elastomer: TDI jutiyo kudu pi yubu polyurethane elastomers, ma diyo kit pa rubber ku plastic. Elastomers eni nwango tic i kabedu madwong, calu i yubu tyend wara, kama gi miyo bedo maber, rii, man jwigo ret. Jutiyo kudu de pi yiku seals man gaskets, kama kero migi mi juku kemikol, lyethu, man lyethu ma lee miyo gibedo ber pi tic kudu i kabedu ma tek.

Yore mi yiko

Yore mi Phosgenation macon
2,4 - Amino Toluene Route: Tic ne ucaku ku lwoko 2,4 - amino toluene man lwoko i chlorobenzene. I ngeye judwoko piny eni ku phosgene i yore aryo. Mir acel, lyethu ma piny timere ikind lyethu ma romo 35 - 45°C. I ngeye, lyethu ma malu timere i lyethu ma piny pa 130°C. I ngei ma timo ne uthum, nitrogen gas jukelo pi wodhu hydrogen chloride man phosgene ma ukadhu. Chlorobenzene juwodhe woko, man timo mir ajiki uketho i iye vacuum distillation pi nwangu TDI maleng.
Nitro Toluene Route: I yore maeni, nitro toluene juyike nitrated man judwoko piny ni nwangu 2,4 - diaminotoluene. Piny ma ikin piny eni juyike i phosgenation, kama edwoko ku phosgene mi yubu TDI. I ngeye jutimo tic ku jam ma jucwalo kudu pi poko man yiko piny ma juyubu ku TDI.
Yore mange ma nyen
Non - Phosgene Routes: I kind oro ma ukadhu, dhanu ubedo ka ketho wigi ikum yubu yore ma epe ku phosgene pi yubu TDI pi jwigo peko ma bino pi tic ku phosgene. Ku lapor, lembe moko ma jutimo ubeyenyo tic ku jam tic mange man kite ma jutimo kudu tic pi yubu TDI manangu epe ku yeny pa phosgene. Ento, yore eni podi gitiye i rwom mi dongo man podi dhanu mapol ungiyo ngo.

Peko mi yot kum: TDI vapor kelo peko madit ikum yot kum pa dhanu. Etimo marac ikum wang, adila, man yore mi yweyo. Bedo i iye pi kare malac nyo wang mapol ecopu nyayu peko mi yot kum, ikinde utiye peko mi yuyu calo bronchitis, asthma - calu lanyuth, man i kare mukende, kadi peko ma rac uloyu calu bronchiectasis man twoyo mi adunde. Ku lapor, oyo ma juketho i rwom ma romo (0.5 - 1)×10−6 pi sawa 6 kubang ceng, pi nindu 5 - 10, junyutho nia gicopo nwangu adwogi marac. I dhanu, yweyo ma romo 0.0005mg/L copo nyayu aonda ma tek man yuyu ma nok.

Peko mi wang man lyethu: TDI ubedo pii ma wango mac, man yamo pare copo bedu piny ma wango mac ku yamu. Ka juketho i mac ma lyel, lyethu, nyo lyethu ma tek, etiye ku peko madit mi wang man wang. Pieno, gwoko man gwoko piny maber piretek pi jwigo peko ma kumeno.
Gwoko man tiyo kudu: TDI umaku juketh i ot ma ngic, ma yamo wok iye maber, ma bor ku lero pa ceng, piny ma lyethu, man piny ma nyayu mac. Kabedo mi kano piny ucikere ni bedo ma jugwoko maber pi jwigo pii ma wok kud i iye. Ni lubre ku kero pare mi timo lembe ku pii man piny mukende, umitu jugwoke woko ku piny ma copo timo lembe kude, calu oxidizing agents. I kare ma jutiyo kudu, jam gwoko kum maber, ikinde gloves ma jukutho ku kemikol, safety goggles, man jam gwoko yuyu, umaku juketh pi jwigo peko mi nwangu two.
