Anaerobic sealant - mankhwala kuti ntchito mpweya permeable sing'anga, mwachitsanzo, zitsulo ndi pulasitiki timachubu, ndipo sasintha dongosolo wake chifukwa katundu wake.

Nthawi zambiri, ndi anaerobic sealant umagwiritsidwa ntchito machitidwe yoyenda yokha Kutentha monga sealant, kuti akhale patsogolo mosadodometsedwa ntchito dongosolo. Chifukwa magwiridwe ake, mankhwala amapereka kusindikiza wathunthu wa welds ndi, yamazinga kugwirizana kusindikiza mtundu, ulusi zisindikizo pa mipope ndi mfundo chitoliro, ndi kukonza zosiyanasiyana cylindrical chuma chilichonse.

Anaerobic sealant limapangidwa popanga mfundo zotsatirazi:

• monomers kapena oligomers wa akiliriki;

• anapereka zinthu zimene zimachititsa kuti ntchito imagwiridwa;

• stabilizers;

• zina zosiyanasiyana monga nthumwi thickening, mitundu.

Zinthu ndi ziwalo wapadera, Akugulitsa kwa nthawi yoyamba inatuluka mu 50s mu United States.

Pa yochepa nthawi, anaerobic sealant wakhala otchuka pakati osiyanasiyana ogula, popeza palibe zinthu sangathe kupereka apamwamba kusindikizidwa kwa slits yopapatiza. Izi Chinawonjezeka mu kusiyana kumene mogwirizana ndi mpweya, potero kusintha zikuchokera zinachitika ndipo anatembenuzidwa zinthu yowirira potero kuteteza ulusi kuchokera mpweya ndi kuwonongeka ena.

Sealant ntchito kunja ayenera kusankhidwa monga momwe ntchito. Zochita ambiri mankhwala ena omatira ntchito kachitidwe Kutentha monga sealant a. Pankhaniyi n'zotheka kugula mankhwala okwera mtengo, monga kutentha opaleshoni sadzakhala upambana 300 ndi -196 madigiri Celsius, kwa Kutentha kutentha dongosolo sangathe.

Njira Pankhaniyi kuti sealant kutentha osiyanasiyana amene adzakhala: - 60 +150. Wokwanira chinthu chovuta zikuchokera amatiteteza motsutsana kuwonongeka acidic ndi zamchere omwe angagwe mwa dongosolo Kutentha, potero akhoza kusankha sealant aliyense, zilibe ngakhale ayenera oyendetsa mfundo zimene mankhwala ntchito monga coolant.

Ngati kumene anaerobic sealant ntchito monga sealant si mu dongosolo Kutentha, ndi kusindikiza mfundo pambuyo kuwotcherera, ayenera kusankhidwa kutenga nkhani zofunika kale zina. The zakuthupi ayenera musaumitse mwamsanga ntchito ndi kukhudzana firmer ndi mtundu wina wa zitsulo.

Zikatero, ngati zinthu kuti ntchito m'malo ndi kutentha, izi wafuna sealant ndi osiyanasiyana onse a kutentha ndi kugwira ntchito.

Posankha sealer n'kofunika kuganizira chilengedwe chimene zidzagwiritsidwanso ntchito - chisindikizo kapena zisindikizo! Kuchokera pamenepa, kodi kwenikweni zimadalira pa moyo wautali ntchito ndi utumiki moyo wa mbali ankachitira zinthu ndi. Ndiyamika apamwamba anaerobic sealant, mukhoza kuthetsa mavuto ambiri, pamene simuyenera kulipira limanena yaikulu ndalama.
