Desmodur re yog ib tus neeg sawv cev sib cav sib ceg heev, Siv nyob rau hauv cov nplaum ua los ntawm hydroxyl polyurethane, Cov Roj Hmab lossis Khoom Siv Hluav Taws Xob,
Nws muaj zoo bonding Lub zog hauv Roj Hmab thiab Cab tau siv nyob rau hauv Resin, Antioxidant, yas tus neeg sawv cev, lub siab-rhiab thiab lwm yam.
Nws tuaj yeem raug siv ua tus ntoo khaub lig es tsis txhob siv Bayer Desmodur re
Muaj ob hom nplaum sib xyaw yuav tsum tau siv nyob rau hauv lub sijhawm thov tom qab muab tso rau hauv re.
Qhov ntev ntawm lub sijhawm siv tsis muaj feem xyuam nrog cov ntsiab lus polymer ntawm cov nplaum, tab sis kuj tseem muaj feem xyuam, antioxygen, cinester, kuab tshuaj, kev txawj ntse, thiab lwm yam.
Thaum nyob ze rau lub sijhawm siv tau, feem ntau yog ob peb teev lossis ib hnub ua haujlwm, nplaum yuav nyuaj rau kev ua haujlwm, thiab viscosity nce sai sai.
Thaum kawg, nws dhau los ua Irreversible Jelly. 100 zoo nplaum nplaum, hydroxyl polyurethane (Polyurethane account rau ib ncig 20%), rov qab qab 4-7. Chloroprene roj hmab (roj hmab nyiaj rau ib ncig 20%), rov muaj 4-7.
Desmodur Re yog feem ntau siv los ua ib qho nyuaj lossis crosslinker hauv ntau polyurethane tsim. Cov ntawv thov suav nrog:
1. Cov txheej txheem: desmodur Re feem ntau yog siv rau hauv kev tsim cov txheej txheem ntawm kev ua haujlwm siab, suav nrog kev siv tsheb lag luam. Nws txhim kho lub durability, tshuaj lom neeg tiv taus thiab huab cua tiv thaiv ntawm cov txheej txheej.
2. Cov nplaum: siv nyob rau hauv kev tsim cov polyurethane nplaum nplaum los txhim kho kev sib raug zoo lub zog thiab kev tawm tsam rau ib puag ncig cov khoom.
3. Leem Nqes: Desemodur Rov qab siv rau hauv cov phuam mus los txhim kho kom yooj yim, kev ua yeeb yam thiab noo noo thiab tshuaj lom neeg kuj.
4. Ua npuas dej: Hauv qee kis, nws tuaj yeem siv los tsim cov khoom siv hloov tau lossis nruj ua npuas dej, pab txhim kho nws cov khoom siv thiab kev ruaj khov.
5. Elastomers: Nws tseem siv rau hauv cov qauv ntawm polyurethane elastomers, uas yuav tsum muaj cov yam ntxwv ua tau zoo xws li, elasticity tsis kam.
Thov muab tso rau hauv lub pas dej qub hauv hnub nyoog qis dua 23 ℃, cov khoom tuaj yeem khaws cia ruaj khov rau 12 lub hlis.
Nws rhiab heev rau qhov kev tshaj plaws; Nws yuav tau tsim cov pa roj carbon dioxide thiab insoluble urea hauv cov tshuaj tiv thaiv nrog dej.
Yog hais tias raug rau teh huab cua los yog lub teeb, nws yuav ceev tau xim hloov, tab sis cov kev ua haujlwm yuav tsis cuam tshuam.
Txhawm rau kom tsim tau kom tsim desmodur Re, ua raws cov lus qhia no:
1. Kub: Khw Desmodur Re rau qhov chaw txias, qhuav. Pom zoo cia kub yog feem ntau nyob nruab nrab ntawm 15 ° C thiab 25 ° C (59 ° F thiab 77 ° F). Zam kev ua kom sov siab.
2. Thawv: Khaws cov khoom lag luam hauv cov thawv qub, kaw ntov kom tiv thaiv kom tsis txhob muaj dej noo thiab paug. Nco ntsoov tias lub thawv ntim tau ua los ntawm cov khoom siv tau tshaj kom tsis txhob muaj kev tawm tsam.
3. Qhov cua: khw muag khoom hauv qhov chaw muaj pa kom txo qis vapor perpectulation. Zam kev cia khoom nyob ze ntawm hluav taws lossis cua sov.
4. Vaum noo: Tiv thaiv los ntawm noo noo thaum asocyanates hnov mob nrog dej, ua rau kev tsim cov pa roj carbon dioxide thiab tsim cov xwm txheej muaj kev phom sij.
5. Kev ceev faj kev nyab xeeb: Ua kom cov chaw ntim khoom tau nruab nrog cov khoom siv kev nyab xeeb uas tsim nyog (PPE) los tswj kev tsim nyog lossis nchuav thaum muaj dej xau lossis txeej.
6. Hnub tas sij hawm: Tshawb cov chaw tsim khoom pom zoo rau lub neej ua haujlwm thiab hnub tas sij hawm. Siv cov khoom lag luam tsis pub dhau lub sijhawm teev tseg rau cov txiaj ntsig zoo tshaj plaws.
750 g / lub raj mis lossis 50 kg / nruas lossis 180 kg / nruas lossis raws li cov neeg siv khoom.
* Peb tuaj yeem muab cov tsheb thauj khoom sib txawv raws li cov neeg siv 'xav tau.
* Thaum qhov ntau yog me me, peb tuaj yeem xa khoom los ntawm cov huab cua lossis thoob ntiaj teb, aws, orgs thiab ntau yam ntawm thoob ntiaj teb thauj cov kab tshwj xeeb.
* Thaum muaj nuj nqis yog loj, peb tuaj yeem xa nkoj los ntawm hiav txwv los xaiv chaw nres nkoj.
* Dhau li, peb kuj tuaj yeem muab cov kev pabcuam tshwj xeeb raws li cov neeg siv khoom siv 'kev xav tau thiab cov khoom lag luam.
Yog lawm, Desmodur Re, zoo li lwm tus neeg, tuaj yeem ua rau tib neeg yog tias tsis ua kom zoo. Nov yog qee cov ntsiab lus tseem ceeb txog nws cov teebmeem kev noj qab haus huv:
1. Inhalation: Raug rau Isocyanate vapors tuaj yeem ua rau lub pa ua pa thiab tej zaum yuav ua rau cov tsos mob ua pa ua rau mob hawb pob uas zoo li nyob rau qee tus neeg.
2. Kev tiv toj tawv nqaij: desmodur rov tuaj yeem ua rau cov tawv nqaij khaus thiab tsis zoo. Lub sijhawm ntev lossis rov qab sib cuag yuav ua rau cov tawv nqaij ua xua.
3. Kev Tiv Thaiv Qhov muag: Tej zaum ua rau muaj qhov muag hnyav thiab kev puas tsuaj. Hnav cov tsom iav tiv thaiv thaum tuav cov khoom no.
4. Kev siv (noj ntawm ISOCYANATES yuav muaj kev phom sij thiab yuav tsum zam.
5. Kev ceev faj kev nyab xeeb: Thaum ua haujlwm nrog Desemodur Re, PPE) yuav tsum tau siv, xws li hnab looj tes thiab kev tiv thaiv thiab tsim nyog. Xyuas kom meej tias qhov chaw ua haujlwm tau txhaj tshuaj tau zoo kom txo tau.
Thaum thauj Desmodur Re, kev ceev faj yuav tsum tau ua raws li kom muaj kev nyab xeeb thiab tswj kev ua raws. Nov yog qee qhov kev txiav txim siab tseem ceeb los coj mus rau hauv tus account:
1. Daim ntawv lo: Xyuas kom cov thawv ntim tau zoo raws li kev cai tswj hwm. Cov ntawv lo tau muaj xws li cov cim kev phom sij thiab cov lus qhia daws teeb meem.
2. Ntim: Siv cov ntim ntim uas tsim nyog uas tau sib xws nrog Isocyanate. Lub thawv yuav tsum tau muab khi rau kev tiv thaiv kom tsis txhob muaj kev xau thiab ua rau ya raws.
3. Kev ntsuas kub: Thauj hauv qhov chaw kub-tswj thiab tsis txhob muaj qhov kub thiab txias, uas yuav cuam tshuam rau kev ruaj ntseg ntawm cov khoom.
4. Qhov cua: xyuas kom meej tias lub tsheb thauj tau zoo ventilated los txo cov kev sib txuam ntawm cov vapors.
5. Cov khoom siv tiv thaiv tus kheej (PPE): Cov neeg ua haujlwm koom nrog PPE tsim nyog yuav tsum hnav cov hnab looj tes tsim nyog yuav tsum tau hnab looj tes tsim nyog
6. Cov txheej txheem txheej xwm thaum muaj xwm ceev: tau paub txog cov txheej txheem thaum muaj xwm ceev thaum muaj nchuav lossis txeej thaum thauj khoom. Muaj roj tswj cov ntaub ntawv npaj txhij.
7. Zam kev ua tsis sib xws cov tshuaj: khaws cia Desmodur rov qab los ntawm cov dej tsis sib xws xws li dej, dej cawv, muaj zog acids lossis hauv paus ua rau cov tshuaj tiv thaiv no.
8. Kev tswj hwm ua raws li: Ua raws li txhua lub zos, cov kev pab hauv tebchaws thiab thoob ntiaj teb hais txog kev thauj mus los ntawm cov kev cai tshwj xeeb rau ISOCYANATIVE.
Rau cov ncauj lus kom ntxaws txog kev thauj ceev faj thiab kev ntsuas kev nyab xeeb, thov saib cov ntaub ntawv kev nyab xeeb (SDS) ntawm Desmodur Re.
