TDI yog ib qho ntawm cov polyisocyanates, uas yog lub hauv paus tseem ceeb rau kev tsim cov khoom siv polyurethane (PU). Hauv kev lag luam polyurethane, feem ntau siv TDI yog sib xyaw ntawm 2, 4-TDI thiab 2, 6-TDI. Peb qib kev lag luam muaj xws li TDI-80/20, TDI-100, thiab TDI-65/35. Cov lej hauv cov qib no sawv cev rau cov ntsiab lus piv ntawm 2,4-TDI. Piv txwv li, TDI -80/20 txhais tau hais tias nws muaj 80% 2, 4-TDI thiab 20% 2,6-TDI; thaum TDI -100 yuav luag tag nrho ntawm 2, 4-TDI, nrog rau cov ntsiab lus ntawm 98%
Daim ntawv thov
Kev siv tseem ceeb
Soft foam plastics:TDI polyurethane yog siv los tsim cov yas ua npuas ncauj, uas feem ntau siv rau hauv rooj tog, txaj, rooj zaum hauv tsheb thiab cov khoom ntim. Mos ua npuas ncauj yas muaj qhov zoo elasticity thiab softness, muab kev txhawb nqa zoo thiab kev poob siab.
Rigid foam plastics:Rigid foam plastics yog siv rau hauv cov khoom siv rwb thaiv tsev, cov khoom siv tub yees thiab cov yeeb nkab rwb thaiv tsev. Vim nws zoo thermal rwb thaiv tsev thiab lub zog, nws yog dav siv nyob rau hauv lub zog-txuag vaj tse thiab muaj rwb thaiv tsev.
Coatings:TDI polyurethane txheej yog dav siv nyob rau hauv automotive, shipbuilding thiab kev lag luam vim lawv hnav tsis kam, tshuaj corrosion kuj thiab zoo heev adhesion zog.
Adhesives thiab sealants:TDI polyurethane adhesives thiab sealants yog haum rau ntau yam kev lag luam daim ntaub ntawv vim lawv hnav tsis kam, tshuaj corrosion kuj thiab zoo heev bonding zog.
Elastomer:TDI polyurethane elastomer yog siv los ua ntau yam ntaub ntawv elastic thiab muaj elasticity zoo thiab txhua yam khoom.

packing Thiab Cia
Vim tias TDI yog khaus rau qee qhov, nws muaj qee yam cuam tshuam rau tib neeg kev noj qab haus huv. Thaum ntsib nrog TDI, yuav tsum muaj kev tiv thaiv tsim nyog, xws li hnav lub npog ntsej muag roj thiab tsis txhob sib cuag nrog daim tawv nqaij. Tsis tas li ntawd, kev saib xyuas tshwj xeeb yuav tsum tau them thaum lub sijhawm khaws cia thiab kev thauj mus los kom ntseeg tau tias lub thawv yog airtight kom tsis txhob xau.
Ntim:
250kg net hnyav steel nruas.
Kev thauj mus los:
TDI yog tshuaj lom neeg. Lub npe, kev phom sij, hnub tsim khoom, chaw tsim khoom thiab lwm yam ntaub ntawv ntawm cov tshuaj yuav tsum tau cim kom meej meej ntawm lub ntim kom cov kev ntsuas raug raug coj los siv thaum muaj xwm txheej ceev. Lub tsheb thauj khoom TDI yuav tsum muaj cov chaw muaj kev nyab xeeb zoo sib xws, xws li kev tiv thaiv hluav taws, tiv thaiv kev tawg, thiab tiv thaiv kom tsis txhob tawg, thiab xyuas kom meej tias cov neeg tsav tsheb thiab cov neeg saib xyuas muaj cov txuj ci sib xws thiab muaj peev xwm tuav xwm ceev. Thaum xa tawm ntau cov khoom thauj los ntawm hiav txwv, TDI tuaj yeem ua ke nrog Chav Kawm 3, Chav Kawm 4.1, Chav Kawm 6.1, Chav Kawm 8, thiab Chav Kawm 9 cov khoom txaus ntshai hauv ib lub thawv, tab sis nws yuav tsum yog palletized thiab cov ntaub ntawv thauj mus los thiab daim ntawv pov thawj yuav tsum tau muab.
Cia:
TDI 80/20 ntim yuav tsum tau kaw kom zoo thiab khaws cia hauv tsev nyob rau hauv qhov chaw muaj cua zoo thiab muaj hluav taws kub. Thaum qhib lub thawv, cov neeg ua haujlwm yuav tsum hnav go les, hnab looj tes thiab roj hmab aprons.Containers yuav tsum tau ua tib zoo saib xyuas kom tsis txhob muaj kev puas tsuaj. Nyob rau hauv cov ntaub ntawv ntawm to, hloov nws mus rau lwm lub thawv kom zoo nyob rau hauv ib tug zoo-ventilated qhov chaw thiab qhuav. Thaum qhib lub hau, siv lub qhov qhib los yog cov ciaj ntswj. Thaum lub hau yog loosened, nres kom txog thaum lub siab siab nyob rau hauv lub thawv sib npaug nrog lub atmospheric siab, ces qhib lub hau maj mam.
Thov nco ntsoov tias cov lus qhia saum toj no tsuas yog siv rau kev siv xwb. Kev thauj mus los tshwj xeeb thiab kev cia khoom yuav txawv nyob ntawm thaj tsam thiab cov kev cai tswj hwm. Cov neeg muas zaub uas tab tom yuav Toluene Diisocyanate zoo siab txais tos los tham nrog peb.
