Mofan Polyurethanes Co., Ltd., tus thawj coj hauv kev tsim kho tshiab hauv kev siv tshuaj polyurethane siab heev, tau tshaj tawm tias nws yuav tsim ntau yam khoom siv rau nws tiam tom ntej.Novolac PolyolsTsim los ntawm kev tsim kho kom raug thiab kev nkag siab tob txog cov kev xav tau ntawm kev siv hauv kev lag luam, cov polyols siab heev no tau teeb tsa los txhais cov qauv kev ua tau zoo rau cov polyurethane ua npuas ncauj thoob plaws ntau yam kev lag luam.

Cov ua npuas polyurethane ruaj khov yog cov khoom siv tseem ceeb hauv kev rwb thaiv tsev, kev tsim kho, kev tub yees, kev thauj mus los, thiab kev tsim khoom tshwj xeeb. Lawv muaj nqis rau lawv qhov kev rwb thaiv tsev zoo heev, lub zog kho tshuab, thiab kev ruaj khov. Txawm li cas los xij, raws li kev thov ntawm kev ua lag luam hloov pauv - tsav los ntawm cov cai tswjfwm kev siv hluav taws xob nruj dua, cov qauv kev nyab xeeb siab dua, thiab qhov xav tau cov kev daws teeb meem zoo rau ib puag ncig - cov chaw tsim khoom tab tom nrhiav cov khoom siv raw uas tsis yog tsuas yog ua tau raws li tab sis dhau qhov kev xav tau no.

Mofan's Novolac Polyols sawv cev rau kev dhia mus tom ntej hauv kev siv tshuab polyurethane. Nrogviscosity qis, tus nqi hydroxyl (OH) zoo tshaj plaws, cov qauv cell zoo heev, thiab kev tiv thaiv hluav taws kub, cov polyols no ua rau cov neeg tsim ua npuas dej ua tiav cov khoom lag luam zoo dua thaum ua kom zoo dua qub thiab siv hluav taws xob.

1. Qhov Viscosity Tsawg thiab Tus Nqi OH Zoo Tshaj Plaws: Kev Ua Haujlwm Zoo Sib Xws Nrog Kev Yooj Yim Tsim Qauv

Ib qho ntawm cov txiaj ntsig zoo tshaj plaws ntawm Mofan's Novolac Polyols yog lawvviscosity tsawg heev, xws li ntawm8,000–15,000 mPa·s ntawm 25°CQhov viscosity txo qis no ua rau kev tuav tswj hwm thaum lub sijhawm tsim thiab tsim khoom zoo dua, ua rau kev sib tov du dua, ua tiav sai dua, thiab txo qis kev ntxhov siab ntawm cov khoom siv tsim khoom. Nws kuj tseem pab txhawb rautxo kev siv hluav taws xob, vim tias yuav tsum muaj cua sov thiab kev co tsawg dua kom ua tiav qhov sib xyaw ua ke.

Ntxiv rau, qhovTus nqi hydroxyl (OHV)ntawm Mofan's Novolac Polyols tuaj yeem ua taukev cai tshwj xeeb ntawm 150–250 mg KOH/gCov kev hloov kho no muaj cov chaw tsim khoom ua npuas ncaujkev ywj pheej ntau dua ntawm kev tsim cov qauv, tshwj xeeb tshaj yog raucov qauv tsim dej ntau, uas yog qhov tseem ceeb rau qee yam kev rwb thaiv tsev thiab cov ntawv thov ua npuas ncauj. Los ntawm kev tswj tus nqi OH, cov neeg tsim qauv tuaj yeem kho qhov nyuaj ntawm ua npuas ncauj, qhov ceev, thiab qhov ceev ntawm qhov sib txuas, kom ntseeg tau tias muaj kev ua tau zoo tshaj plaws rau kev siv kawg.

2. Cov Qauv Cell Zoo Kawg Nkaus: Cov Khoom Siv Thermal thiab Mechanical Zoo Tshaj Plaws

Kev ua haujlwm ua npuas dej yog cuam tshuam los ntawm nws cov qauv sab hauv. Mofan's Novolac Polyols xa ib qhoQhov nruab nrab ntawm cov cell loj tsuas yog 150–200 μm, uas yog qhov zoo dua piv rau qhov300–500 μmfeem ntau pom muaj nyob rau hauv cov qauv polyurethane ua npuas ncauj.

Cov qauv ultrafine no muab ntau yam txiaj ntsig:

Kev Rwb Thaiv Kub Zoo Dua- Cov cell me dua, sib npaug dua txo qhov kev sib txuas thermal, yog li ua kom cov ua npuas ncauj ua haujlwm rwb thaiv tsev zoo dua.

Kev Ruaj Ntseg Zoo Dua- Cov qauv cell zoo thiab sib xws txo qhov kev ntswj lossis nthuav dav dhau sijhawm, ua kom ntseeg tau tias muaj kev ntseeg siab mus sij hawm ntev.

Lub Zog Kho Kom Zoo Dua- Cov hlwb me me ua rau muaj zog compressive ntau dua, uas yog ib qho tseem ceeb hauv cov vaj huam sib luag rwb thaiv tsev thiab cov ntawv thov ua npuas ncauj.

Tsis tas li ntawd xwb, Mofan's Novolac Polyols tsim cov ua npuas dej nrog ib qhoQhov piv ntawm cov hlwb kaw tshaj 95%Cov ntsiab lus kaw-cell siab no txo ​​qhov nkag ntawm cov dej noo lossis cua, uas yog qhov tseem ceeb rau kev tswj hwm cov cua sov qis thoob plaws lub neej ntawm cov khoom.

3. Kev Tiv Thaiv Hluav Taws Xob: Kev Nyab Xeeb Uas Muaj Hauv Paus Tsis Muaj Kev Cuam Tshuam Rau Kev Ua Haujlwm

Kev nyab xeeb hluav taws yog qhov kev txhawj xeeb tas li hauv kev rwb thaiv tsev thiab cov ntaub ntawv tsim kho, tshwj xeeb tshaj yog thaum cov cai tsim kho thoob ntiaj teb thiab cov cai kev nyab xeeb dhau los ua nruj dua. Mofan's Novolac Polyols featurekev tiv thaiv hluav taws xob-txhais tau tias qhov hluav taws tsis kam yog ib qho tseem ceeb ntawm cov qauv tshuaj ntawm cov khoom siv, tsis yog tsuas yog qhov tshwm sim ntawm cov khoom ntxiv xwb.

Kev ntsuam xyuas calorimeter ntawm lub khob hliav qab ywj pheej qhia tau tias cov ua npuas polyurethane tawv uas tsim los ntawm Mofan's Novolac Polyols ua tiav ib qhoTxo 35% ntawm qhov siab tshaj plaws ntawm kev tso tawm cua sov (pHRR)piv rau cov ua npuas ncauj ruaj khov ib txwm muaj. Qhov pHRR qis dua no txhais tau tiasnplaim taws qeeb qeeb, txo cov pa luam yeeb, thiab txhim kho kev nyab xeeb hluav taws, ua rau cov khoom siv no zoo heev rau cov ntawv thov hauv tsev, chaw ua lag luam, thiab chaw ua haujlwm.

Qhov kev tiv thaiv hluav taws uas muaj nyob hauv kuj muaj txiaj ntsig zoo rau kev ua cov khoom no: cov chaw tsim khoom tuaj yeem txo lossis tshem tawm qhov xav tau cov tshuaj ntxiv uas tiv thaiv hluav taws sab nraud, ua rau cov qauv yooj yim dua thiab tej zaum yuav txo cov nqi tsim khoom.
