Global - Premier TDI: Say Important Building Block ed Industriya na Polyurethane

Pisikal tan Kemikal iran Kablian

Itsura tan Angob: Say TDI et kaslakan ya ompatnag ya andiay kolor ya transparent odino medyo duyaw, mainomay ya napoolan a likido. Mangibubuga na makapasinagem, mabiskeg, tan makapaermen ya angob, ya manseserbin importantin pakapatnagan na kiwawala to.
Solubility tan Reactivity: Nayarin mainomay itan ya ilaok ed nanduruman organikon solvent a singa say ethanol (ya walay decomposition to), diethylene glycol monoethyl ether, diethyl ether, acetone, carbon tetrachloride, benzene, chlorobenzene, kerosene, tan olive oil. Sakey ed saray sankatalonggaringan a kemikal a kablian to et say inka-reaktibo to ed danum, sakey a reaksion a mamawala na carbon dioxide gas. Niarum ni, say TDI et maples ya makareak ed saray compound ya walaan na aktibon hydrogen atoms, sakey a kablian ya uusaren ed dakel a proseso ed industriya.
Saray Manunan Pisikal ya Agmanguman: Say TDI et walay boiling point to ya manga 247°C, ya mangidetermina ed temperatura no kapigan itan manlapud likido ya anggad gas ya estado diad silong na normal ya presyon na atmospera. Say melting point to et manlapud 19.5 anggad 21.5°C, ya mangipapanengneng na temperatura no kapigan itan onlelereg. Say flash point na TDI et 127°C, kabaliksan to ya diad sayan temperatura, makapawala na singa napoolan ya singaw no walay ignition source. Diad relatibon densidad ya 1.217, mas makapal itan nen say danum, ya walay implikasyon to ed panangasikaso tan pangibiig ed satan diad industriyal tan kaliberliber.

Saray Lugar na Aplikasyon

Polyurethane Foam Production: Say TDI so manunan sengegan na panaggawa na polyurethane foams, ya malaknab ya uusaren ed dakel ya industriya. Diad sektor na muebles, saray soft polyurethane foams ya ginawa ed TDI so materyal ya pilien parad panggawa na komportable tan makatulong iran unan ed saray sopa, armchair, tan kutson. Diad industriya na luluganan, sarayan foam et uusaren ed saray yurongan na luluganan, ya mangiiter na ligliwa tan kaligenan diad pangisesep ed saray shock legan ya manmamaneho. Niarum ni, saray TDI - based polyurethane foams et uusaren ed saray aplikasyon na insulasyon, a singa saray refrigerator tan saray materyales ya insulasyon na bilding, lapud ekselentin thermal insulation properties da.
Saray Coating tan Adhesives: Say TDI et walay importantin betang to ed panaggawa na saray coating tan adhesives ya atagey so kalidad da. Diad industriya na saray coatings, saray TDI - based polyurethanes et uusaren pian makagawa na matibay, ag-onkupas, tan ag-onkupas ed kemikal iran coating parad nanduruman klase na substrate, kaiba lay metal, plastik, tan tabla. Sarayan coating et uusaren ed saray automotive finish, floor coating, tan industrial equipment coating. Diad tindaan na adhesives, saray adhesives ya walay TDI to et papablien lapud mabiskeg ya pakayari dan manpeket. Uusaren iratan ed panagtipon na muebles, panag-bond na saray kabiangan na luluganan, tan diad industriya na konstruksion parad panagtipon na nanduruman materyales ed panagpaalagey.
Panaggawa na Elastomer: Say TDI et uusaren pian makagawa na polyurethane elastomers, ya mankokombina na saray kablian na goma tan plastik. Sarayan elastomer et nausar ed nanduruman lugar, singa say panaggawa na dapan na sapatos, ya ditan et mangiiter iratan na ekselentin inka-flexible, inka-durable, tan shock absorption. Uusaren met iratan ed panaggawa na saray seal tan gasket ed industriya, ya say resistensya ra ed saray kemikal, abrasion, tan atagey a temperatura so manggagawa ed sikaran matukoy ya usaren ed mairap iran kaliberliber.

Paraan na Panagparaan

Tradisyonal iran Rota na Phosgenation
2,4 - Amino Toluene Route: Say proseso et onggapo ed pantunaw na 2,4 - amino toluene tan pantunaw ed chlorobenzene. Sayan solusyon et manreak ed phosgene diad duaran kundang a proseso. Unona, say reaksion na abeban temperatura et nagagawa ed loob na temperaturan 35 - 45°C. Kayari to, walay atagey a temperaturan reaksion ya nagagawa ed temperaturan abeba nen 130°C. Kayari na saray reaksion, say nitrogen gas so iloob pian naekal so antokaman ya ag-akareak ya hydrogen chloride tan sobran phosgene. Say chlorobenzene et i-distill, tan say unor ya kundang et say vacuum distillation pian naala so puron TDI.
Nitro Toluene Route: Diad sayan paraan, say nitro toluene et unonan nitrated insan nabawasan pian naala so 2,4 - diaminotoluene. Sayan intermediate et ipaarap ed phosgenation, ya ditan et onreak ed phosgene pian manporma na TDI. Say reaction mixture et iproseso pian nasian tan nalinisan so produkto na TDI.
Saray Onlelesa ya Alternatibon Paraan
Non - Phosgene Routes: Diad apalabas iran taon, walay ondarakel ya pokus ed pamawala na saray paraan ya aliwan phosgene pian makapawala na TDI diad panggugunaet ya nabawasan so epekto ed kaliberliber ya nausar na phosgene. Singa bilang, wala ray research ya manguusisa ed pangusar na alternatibon reagents tan kondisyon na reaksion pian makagawa na TDI ya agla kaukolan so phosgene. Balet, sarayan paraan et wala ni ed yugtan na panagpaalagey tan agni nadampot so malaknab a komersyo.

Panalwar

Peligro ed Salud: Say TDI vapor et walaan na baleg a peligro ed bunigas na too. Makapaermen itan ed mata, baog, tan panag-ehersisyo. Say andukey odino paulit-ulit ya pakapatnagan et nayarin pansengegan na graben problema ed bunigas, kaiba lay problema ed panag-ehersisyo a singa say bronchitis, singa sintomas na asthma, tan diad arum a kaso, mas grabe ni ray kondisyon a singa say bronchiectasis tan pulmonary heart disease. Singa bilang, saray ikol ya nipaarap ed saray konsentrasyon ya manlapud (0.5 - 1)×10−6 ed loob na 6 oras ed sanagew, diad loob na 5 - 10 ya agew, et napatnagan ya onsuko ed saray makasamal ya epekto. Diad too, say pan-inhale na konsentrasyon ya anggad 0.0005mg/L et nayarin pansengegan na grabe ya ugip tan pankulang na panlinawa.

Saray Peligro ed Inkapoolan tan Insabog: Say TDI et sakey a likido ya mainomay ya napoolan, tan saray singaw to et nayarin manporma na makapasabog iran laok ed dagem. No naeksperiensya so apoy, sparks, odino atagey a petang, walay baleg a peligro na pakapoolan tan pakasabog. Kanian, nakaukolan so suston panag-imbantak tan panag-asikaso pian naprebentaan iratan a kapeligroan.
Panangisimpen tan Pangasikaso: Say TDI et nepeg ya isimpen ed ambetel tan maong so dagem ya bodega ya arawi ed direktan sinag na agew, lapuan na petang, tan lapuan na apoy. Saray panangisimpenan et nepeg ya malet ya nasaraan pian ag-onleak so singaw. Lapud sikatoy makareak ed danum tan arum niran substansia, nepeg ya isimpen itan ya nibiig ed saray materyales ya nayarin makareak ed satan, singa saray oxidizing agent. Legan ya mangaawit, nepeg ya isulong so matukoy ya personal protective equipment, kaiba lay chemical - resistant gloves, safety goggles, tan respiratory protection, pian nabawasan so peligro na pakawalaan na sakit.
