Cov tub ntxhais sib txawv ntawm cov kuab tshuaj thiab emulsion-raws li silicone roj
Cov tub ntxhais sib txawv ntawm cov kuab roj silicone thiab emulsion-based-based silicone roj nyob rau hauv lawv cov khoom nruab nrab, tsim, thiab kev thov kev ua haujlwm, thiab kev thov kev ua haujlwm, thiab kev thov kev ua haujlwm, thiab kev thov kev ua haujlwm, thiab kev thov cov yam ntxwv, thiab kev thov kev ua haujlwm, thiab kev thov kev ua haujlwm, thiab kev thov kev ua haujlwm, thiab kev thov kev ua haujlwm, thiab kev thov kev ua haujlwm, thiab kev thov kev ua haujlwm, thiab kev thov kev ua haujlwm, thiab kev thov kev ua haujlwm, thiab kev thov kev ua haujlwm, thiab kev thov kev ua haujlwm, thiab kev thov cov yam ntxwv. Cov kev sib txawv tshwj xeeb yog raws li hauv qab no:
1. Lub hauv paus nruab nrab thiab muaj pes tsawg leeg
Hnyav-Raws Silicone Roj
Nruab nrab:Siv cov khoom siv hluav taws xob tsis huv (xws li Toluene, xyheej, thiab cov roj av ether) raws li cov cab kuj.
Txoj Kev Tsim:Silicone roj (tseemthaiv) + cov kuab tshuaj (dag) + cov nyiaj ntxiv ntawm cov quav ntxiv (xws li antioxidants).
Zog:Pob tshab lossis lub teeb daj ntshiab kua.
Emulsion-based silicone roj
Nruab nrab:Dej pabcuam ua cov theem nruam, nrog cov roj silicone dispersed los ntawm emulsifiers.
Txoj Kev Tsim:Silicone roj (theem sab hauv) + emulsifier (xws li cov tsis yog-ionic semfactants) + dej (sab nraud) + cov stabilizers / privilizers / privilanives.
Zog:Milky dawb los yog ib nrab pob tshab emulsion.
2. Ib puag ncig thiab kev txiav txim siab nyab xeeb
Cov kuab tshuaj-raws li
High VOC content (typically >500g / l), nplaim taws thiab tawg, yuav tsum muaj pov thawj-pov thawj cia.
Kev Txwv Cheeb Tsam:Kev siv tsawg tsawg nyob rau hauv cov kev cai xws li EU ncav cuag thiab Tuam Tshoj lub vocip emission cov cai tswjfwm.
Emulsion-raws li
Tsawg voc lossis xoom voc, ua kom haum nrog cov qauv ib puag ncig, thiab muaj kev nyab xeeb rau kev thauj khoom thiab chaw khaws khoom.
Txiav txim siab:Biodegradity ntawm emulsifiers thiab peev xwm ua rau muaj kev cuam tshuam los ntawm cov tshuaj tiv thaiv (hauv qee qhov qauv).
3. Kev Ua Haujlwm thiab Kev Tso Cai Tso Cai
| Cov yam ntxwv | Hnyav-Raws Silicone Roj | Emulsion-based silicone roj |
|---|---|---|
| Kho lub nrawm | Ceev (ua ib zaj duab xis sai li cov kuab tshuaj yaj) | Slower (nyob ntawm cov dej evaporation / high-kub kho) |
| Kub tiv thaiv | High (pure silicone oil withstands temperatures >200 degree) | Nruab Nrab (qhov kub tsis kam txhim kho tom qab dej evaporation) |
| Kev sib haum | Zoo affinity nrog cov ntaub ntawv tsis-polar (plastics, roj hmab) | Yooj yim nyiaj nrog polar cov ntaub ntawv (fibers, hlau oxides) |
| Cov Kev Siv Raug Raug | Tso cov neeg sawv cev, cov roj nplua nyeem, kub taub hau | Textile softeners, cov khoom tu plaub hau, cov khoom siv tawv nqaij |
4. Cov txheej txheem ntau lawm thiab tus nqi
Cov kuab tshuaj-raws li
Txheej txheem yooj yim:Yuav tsum muaj kev sib xyaw rau lub cev xwb, tsis muaj cov khoom siv emulsification.
Tus nqi pauv sib pab:Cuam tshuam los ntawm cov kuab roj (xws li roj av-raws li cov kuab tshuaj uas tsis siv neeg).
Emulsion-raws li
Cov txheej txheem siab dua:Yuav tsum muaj cov cuab yeej siv hluav taws xob nrawm nrawm, nrog cov qauv tsim qauv rau tus nqi HLB.
Tus nqi ruaj khov:Siv cov dej raws li lub ntsiab tseem ceeb, muab tus nqi ua nqi ntev.
5. Cia thiab Ruaj Ntseg
Cov kuab tshuaj-raws li
Siab ruaj khov: Can be stored long-term (>12 lub hlis) Thaum kaw thiab tau ceev tseg ntawm lub teeb.
Kev pheej hmoo:Cov nplaim, yuav tsum tau muab khaws cia kom deb ntawm qhov chaw taws teeb.
Emulsion-raws li
Kom preizzte ceevfe:Cia cov kub yuav tsum nyob saum 5 qib los tiv thaiv theem sib cais.
Txee Lub Neej:{{0 {0}} lub hlis (yuav tsum muaj cov tshuaj tiv thaiv kom tiv thaiv cov kab mob decomposition).

Cov Qauv Xaiv:
Xum cov kuab tshuaj-raws liRau cov ntawv thov uas xav tau kev kho kom ceev, kub tsis kam, lossis sib xyaw nrog cov tsis yog-polar substrates.
Xum emulsion-raws liRau cov ntawv thov kev phooj ywg ib puag ncig, cov dej ua haujlwm sib xyaw ua ke, lossis ntsuas kub tsawg.
Kev Lag Luam Trend:
Tsav los ntawm cov kev cai ib puag ncig, emulsion-based silicone roj yog maj hloov cov kuab tshuaj solvent-based versions, tshwj xeeb tshaj yog hauv kev saib xyuas tus kheej thiab textile Industries.
