Si-N bonds yooj yim hnov mob nrog hydroxyl-muaj tshuaj thiab tuaj yeem siv los ua amine curing agents. Lawv kuj tuaj yeem siv los hloov kho hydroxyl-muaj resins los txhim kho qhov kub thiab txias, xws li phenolic resins, epoxy resins, alkyd resins, acrylic resins, thiab lwm yam.
Silazanes tau siv dav hauv kev lag luam roj hmab, kev lag luam ceramic, thiab lwm yam. Piv txwv li, silazane yog ib qho khoom siv zoo hauv kev lag luam silicone roj hmab. Lawv tuaj yeem tsis tsuas yog ua raws li cov qauv kev txhim kho kev tswj hwm cov neeg ua haujlwm tab sis kuj txhim kho cov cua sov thiab kev ua haujlwm ntawm cov roj hmab vulcanized. Mechanical zog tau raug txhim kho. Yog li ntawd, silazane yog ntxiv rau lwm cov organic hluavtaws roj hmab ua kev lag luam los txhim kho nws cov thermal stability thiab mechanical zog.

Txheej txheem piav qhia
1. Roughing kev kho mob: Ua ntej thov silazane, grind los yog sandblast lub nto ntawm lub substrate kom tshem tawm xeb, plua plav, av, thiab lwm yam uas txuas rau saum npoo ntawm cov khoom yuav tsum tau kho. Txoj kev kho roughening muaj txiaj ntsig zoo rau cov nyhuv txheej. Qhov zoo tshaj plaws yog Sa2.5 thiab qhov tsawg kawg nkaus yog St3 yam tsis muaj nplai (GB/T 30790.4-2014), yog li thov ua tib zoo saib xyuas.
2. Kev Tu: Siv tus neeg saib xyuas tshwj xeeb lossis tus neeg saib xyuas degreasing kom tshem tawm cov roj, plua plav, thiab lwm yam uas seem rau ntawm qhov chaw roughened.
3. Qhuav lub substrate: Ua ntej thov silazane, xyuas kom meej qhov chaw ntawm lub substrate yog qhuav thiab huv si.
4. Kev sib xyaw xim: Cov khoom no yog ib qho khoom siv. Co kom huv si ua ntej siv thiab lim nws nrog 400 mesh rau kev siv tom qab.
5. Daim ntawv thov xim: Cov txheej txheem tshuaj tsuag ntawm 0 5-1 0 caliber spray rab phom muaj qhov zoo li zoo thiab sib xws.
6. Kev kho: Tom qab txau, cia qhov chaw qhuav rau 10 feeb, tom qab ntawd khaws thiab kho ntawm 180 degree rau 30 feeb (txheej txheej yog siv qis dua 400 degree), lossis 250 degree rau 30 feeb (thaum cov txheej siv saum toj no 400 degree. ).
Kev khaws cia thiab kev thauj mus los
1. Nws yuav tsum tau khaws cia raws li lub teb chaws txoj cai. Qhov chaw cia khoom yuav tsum qhuav, txias, zoo ventilated, thiab deb ntawm tshav kub thiab hluav taws. Cov thawv ntim khoom yuav tsum tau kaw kom nruj thiab khaws cia nrog kev saib xyuas.
2. Qhov ntsuas kub yuav tsum nyob nruab nrab ntawm 5 degree thiab 30 degree, thiab lub sijhawm cia yog 6 lub hlis.
3. Cov xim uas tsis siv yuav tsum muab khaws cia nrog lub hau kaw thiab kaw.
4. Cov xim pleev xim uas tsis tau siv tsis tuaj yeem rov ua dua thiab yuav tsum muab pov tseg raws li cov cai hauv zos.
5. Cov khoom uas tau dhau lub txee lub neej tsuas yog siv tau tom qab dhau qhov kev xeem.
