Kutentha zosagwira utoto, zitsulo: mitundu ndi ukulu

mankhwala kugonjetsedwa utoto anafuna chithandizo zitsulo pamwamba, Ali kuteteza nyumba zosiyanasiyana ku mavuto aakulu dzimbiri chifukwa cha mankhwala weathering zikuchitika m'mikhalidwe opaleshoni kutentha okwera yozungulira. Ngati makoma utoto ndi ng'anjo ochiritsira utoto mafakitale ndi mapaipi, Redieta banja kapena zipangizo zina zilizonse, mchikakamizo cha Kutentha ❖ kuyanika wosanjikiza kugwa kumbuyo pamwamba, ndi zitsulo kuti poyera. Pakhoza kukhala zochepa kuwononga zitsulo, koma zoipa kwa mfundo zokongoletsa maganizo, chodabwitsa - chikasu utoto.

Panopa, makampani mankhwala umabala mitundu yambiri ya inks kutentha zosagwira anaikira penti zitsulo pamalo, malingana ndi chilengedwe kutentha zomwe ntchito ndi mankhwala ina.

Sing'anga imene padziko zitsulo ndi mkangano ndi kutentha 80 ° C, zimathandiza ntchito iliyonse ya utoto.

The kutentha zosagwira utoto chifukwa zitsulo, chidakupangitsani zochokera alkyd ndi akiliriki resins, ntchito ankaudaya nyumba poyera kuti kutentha kwa 100 ° C, lili wapadera kutentha zosagwira zina, amene kupewa pamwamba chikasu pamene usavutike. Childs, mitundu ntchito kudetsa wa radiators banja ndi machitidwe otentha madzi.

Pakuti kudetsa wa njira zosiyanasiyana ndi zinthu structural zikugwira ntchito pa kutentha kwa 120 ° C ntchito kutentha zosagwira utoto chifukwa zitsulo, pogwiritsa ntchito ndi epoxy phunziroli ndi Kuwonjezera nthaka ndi nthaka-mankwala zigawo zikuluzikulu. Epoxy owola Angagwiritsidwenso ntchito pa apamwamba kutentha - mpaka 200 ° C.

Pamene kutentha boma mpaka 400 ° C akulimbikitsidwa kugwiritsa ntchito limodzi chigawo ❖ kuyanika, pachimake munali ethyl silicate ndi epoksiefirnye utomoni. Pa kutentha ichi, ochiritsira inki amatopa amapezeka yomweyo, kotero izi kutentha zosagwira utoto lili ndi zitsulo mu kapangidwe kake chitsulo ufa. kusintha Izi ingagwiritsidwe ntchito nkhani wosanjikiza limodzi.

Mu zikhalidwe opaleshoni, mankhwala kapena dongosolo kutentha osiyanasiyana kuti 650ºC, akatswiri amalangiza ntchito chigawo chimodzi ❖ kuyanika wosakwatiwa, pachimake munali silikoni utomoni. Mu nkhani iyi, kutentha zosagwira utoto umagwiritsidwa pamwamba zitsulo wosanjikiza woonda kwambiri ndi mtengo wa ku microns 30 100.

The boma kutentha owonjezera 650ºC ikukhudza ntchito monga ❖ kuyanika ochekenera nkhani chopangidwa pamaziko a galasi kutentha zosagwira ndi zipangizo gulu.

❖ kuyanika zipangizo mitundu ya mankhwala zachitsulo nawo zikhalidwe za kutentha, ndi kumva kuwawa kukana mkulu, ali amphamvu mofewa, zachilengedwe otetezedwa, zokhalitsa yaitali. Iwo ungagwiritsidwe pamwamba monga mu chipinda chatsekedwa, ndipo panja. The kuipa ntchito kutentha zosagwira inki monga njira kutsatira - deta utoto, mwachitsanzo epoxy utoto , zitsulo, ntchito pamwamba ndi kupopera, ndipo izi kumatanthauza kuchuluka mowa zakuthupi.
