Cov khoom no siv polysilazane ua cov yeeb yaj kiab ua yeeb yaj kiab, suav nrog diluent, retarder, qib tus neeg sawv cev thiab lwm yam khoom ntxiv. Nws yog siv los daws qhov teeb meem ntawm chav tsev kub kev tsim kho thiab chav tsev kub kho uas nyuaj rau kev ua tiav nrog cov txheej txheem ceramic. Cov cwj mem hardness yog siab dua 4H tsis-daj, haum rau txheej kho, hnav-resistant fireproof txheej, hydrophobic nws tus kheej-tshuaj tiv thaiv kev laus txheej rau sab nraum zoov siv, haum rau sab nraum zoov ua hauj lwm tej yam kev mob hauv qab 150 degree thiab luv luv kub kub ua hauj lwm tej yam kev mob ntawm 800 degree, thiab lwm yam. (Ceeb Toom: txawv Cov khoom sib xws rau cov khoom siv hauv paus yuav txawv). Raw cov ntaub ntawv xws li cov tawv nqaij-phooj ywg antibacterial cov xim tseem ceeb tsuas yog siv ionic compounds. Tom qab kho, lawv tsim covalent bonds nrog cov khoom siv hauv paus, uas zoo heev txhim kho lub zog ntawm cov txheej los ntawm kev sib xyaw tshuaj.
Hais txog kev ua haujlwm sib xyaw, nws zoo ib yam li ZG-201. Nws siv tshwj xeeb acid thiab alkali resistant raw cov ntaub ntawv. Cov txheej txheem kev ua tau zoo yog ruaj khov thiab tsis yooj yim rau kev cuam tshuam nrog qhov nruab nrab. Nyob rau tib lub sijhawm, cov khoom siv raw nrog cov qauv ntawv thiab cov qauv pas nrig kuj muaj txiaj ntsig zoo hauv kev tiv thaiv ultraviolet lub teeb thiab tawg. Zoo heev txhawb zog, yog li zoo tiv thaiv ib puag ncig influences. Nws tau dav siv nyob rau hauv aerospace, roj av thiab petrochemical, metallurgy, hluav taws xob, thiab tub rog systems. Nws yog tsim rau kev tiv thaiv corrosion ntawm chimney flues, high-temperature chav kav, tshav kub exchangers, high-temperature furnaces, high-temperature desulfurization khoom, roj av thiab petrochemical cracking khoom, cav qhov chaw, thiab tso cov kav dej.

Txheej txheem piav qhia
1. Roughing kev kho mob: Ua ntej thov 106 chav kub curing 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 mloog.
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 ntawm lub substrate: Ua ntej thov 106 chav tsev kub curing silazane, xyuas kom meej tias lub substrate yog qhuav thiab huv si.
4. Txheej sib xyaw: Cov khoom no yog ib qho khoom siv. Ua ntej siv, 106 chav kub kho silazane yuav tsum tau shaken tag nrho thiab lim nrog 400 mesh rau tom qab siv.
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, kev kho ntawm chav tsev kub yuav tsum tau ua 1 teev rau qhov kov, ntau tshaj 4 teev rau qhov kov, thiab ntau tshaj 24 teev kom qhuav. Nws kuj tuaj yeem kho tau sai sai los ntawm cua sov.
Cov lus qhia tshwj xeeb: Cov khoom no yog ib qho khoom siv uas tuaj yeem kho tau ntawm chav tsev kub. Thov siv nws li ntawm 6 teev tom qab qhib lub thoob. Thaum lub sijhawm tsim kho ntev, cov cuab yeej tsim kho yuav tsum tau muab ntxuav kom tsis txhob muaj cov cuab yeej tsim kho kom ruaj khov. Nws raug nquahu kom txau nws hauv ib qho dhau los thiab cov yeeb yaj kiab qhuav yuav tsum tsis pub tshaj 200um, txwv tsis pub cov txheej txheem txheej yuav raug txo.
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 tsis siv yuav tsum muab 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.
