Nyob rau hauv cov liaj teb ntawm lub tsev dej tsis huv, lub hauv paus kev kho mob, muaj ob qho kev sib txawv ntawm cov khoom siv molyurethanism thiab cov kev sib cav sib ceg ntawm dej- soluble thiab Roj - Soluble cov khoom.starting los ntawm cov kev xav ntawm cov ntaub ntawv kev tshawb fawb thiab sib txuas ntawm cov khoom siv ua haujlwm thiab cov kev siv ntawm ob.
1. Tshuaj Lom Zem: Cov qauv tsim qauv sib txawv ntawm hydrophilic thiab hydrophobic
Dej - soluble polyurethane siv cov lus qhia hydrophilic {2%, cov qauv ntawm eprochures li 50 vib nas this tom qab ntsib dej los tsim ib qho elastic gel muaj urea bonds, cov tshuaj tiv thaiv tus nqi yog 8 {}}}} 10 zaug sai dua li cov roj solubility; Thib ob, lub cev sib xyaw ua ke tuaj yeem nqus tau cov dej ob zaug thiab nthuav dav, tus nqi nthuav dav yog qhov siab li 20 zaug, sib sau ua ib lub hydrogel zoo li clogging network; Thaum kawg, cov ntim hloov pauv ntawm ntub thiab qhuav voj voog mus txog 15% -25%, uas tuaj yeem hloov kho cov kab nrib pleb dynamic.
Cov roj - Soluble cov khoom yog soluble cov khoom yog synthesized los ntawm cov tshuaj pleev kom dawb huv oxide thiab TDI / MDI. Lub Hydrophobicity ntawm cov molecular charn ua rau nws cov tshuaj tiv thaiv ntau heev: thiab cov qauv ua npuas dej tuaj yeem ncav cuag cov qauv ua npuas ncauj, thiab cov qauv ua npuas ncauj tau ua npuas ncauj ntawm cov qauv ua npuas ncauj Tom qab kho, ib lub zog polyurethane / polyurethane network yog tsim, nrog ib qho modulus Elastic ntawm ntau dua 200Mpa, uas yog tsim nyog rau kev teeb tsa kev teeb tsa; Cov dej nqus dej nqus tus nqi ntawm lub cev sib xyaw ua ke yog tsawg dua 0.5%, thiab lub zog ua tau zoo heev, thiab ib puag ncig muaj zog tshaj 95%.
2. Kev sib piv ua tau haujlwm: Los ntawm kuaj cov ntaub ntawv rau kev kuaj xyuas engineering
Hais txog cov dej plugging mechanism, dej- soluble polyurethane ntawm ib lub sij hawm nrawm nrawm rau hauv lub sij hawm luv luv rau 0.3}}}} {{{11 {xyoo Kev rov muaj dua ntawm cov kab nrib pleb dynamic yog tsuas yog 8%, thiab nws yuav tsum tau ua kom muaj zog ntawm 8%, thiab cov roj ntau dhau los ntawm cov roj carbon dioxide Ua kom muaj kev sib tw ntawm cov slurry ntawm cov nplais ntawm lub pas dej tauv, thiab cov ua npuas dej siab yuav ua rau muaj zog tshaj plaws
Nyob rau hauv cov nqe lus ntawm ib puag ncig kev hloov kho, cov tshuaj tiv thaiv tus nqi ntawm dej {}} soluble polyurethane poob qis qis dua 5 degree, thiab ethylene glycolants yuav tsum tau ntxiv; roj - soluble polyurethane tseem tuaj yeem raug txo kom ntau los ntawm 40%. Tom qab 50 khov}}} Roj - Soluble Polyurethane tsuas yog 3% -5%.
3. Engineering Xaiv lub tswv yim: Dhau ntawm kev ua kom muaj kev sib tw ntawm hydrophilic / hydrophobic
Raws li cov kev tso tawm cov txheej txheem tshiab rau cov engineering cov qauv kev ntsuas, nws raug pom zoo rau cov khoom siv fiber ntau, nws raug pom zoo} Solicle Polyurethane Pliv yog xaiv nyob rau hauv rooj plaub ntawm dej exppage; Rau kev tawg nthab, ib 7: 3 dej - soluble / roj soluble sib nraus, thiab roj ntshiab}} soluble yog siv rau cov kab nrib pleb; Rau ib puag ncig kev lom zem, daws - free}} Soluble Polyurethane POLYURETHANE POLYURETHANTY yog xaiv nyob hauv ib puag ncig kev lag luam; Txog cov nqi them, roj {- Soluble POLYurethane tau xaiv cov khoom siv tsawg dua 500 yua} soluble polyurethane hloov nrog mov silica.
Los ntawm cov qauv molecular los tsim qauv kev tsim kho, kev txhim kho ntawm cov dej {}} soluble polyurethane cov khoom siv los tiv thaiv kev tiv thaiv- saib cov thev naus laus zis.
