Choyamba, ndi durability ndi kukana kwa mitundu yosiyanasiyana ya makhalidwe, kuphatikizapo chinyezi ndi kutentha monyanyira. Komanso, zabwino ndi zovuta ntchito, ndipo chifukwa onse kwa guluu wolimba kwambiri osati youma komanso malo yonyowa. Sealant zochokera phula ndi abwino kwa kudzaza ming'alu, mfundo ndi voids pakati pa mapepala zitsulo, komanso malo a denga olumikizidwa kwa lokwera ndi m'chumunicho - izo si umathandiza bwino, komanso likuthandiza munthu zigawo zikuluzikulu.

Pokambirana ndi phula sealant tiyenera kuziganizira kwambiri poizoni, nchifukwa chake n'koyenera yekha ntchito panja. Palibe sagwiritsa ntchito zotsalira za zikuchokera mkati Okhalamo. Kuti adzimvera, tiona makhalidwe kwambiri kutchulidwa ndi katundu zakuthupi:

• mphamvu;

• anatsekera - kwa maziko youma;
• chinyezi - chifukwa ntchito ndi maziko chonyowa ndipo akubwera mu kukhudzana ndi chinyontho.

Polyurethane sealant chotchuka kwambiri mwa omanga masiku ano, zikomo onse kuti chiwerengero cha makhalidwe. Dama:

• mankhwala inertness;
• kukana kuti kuwonongeka ndi zotsatira matenthedwe;
• kuthekera kudetsa;
• Mwachangu;
• durability.

Mwina drawback yekha wa sealant ndi zochokera polyurethane ndi mtengo wake ndi mkulu. Koma likuvutika durability ndi nthenda yotaya Mwachangu n'chofunikira. Komanso, kwa denga sealant pa polyurethane maziko akuti konsekonse. Ndipo mathokozo onse ndi guluu wolimba ake pamalo kwambiri kudziwika: matabwa, zitsulo, njerwa, konkire.

tepi sealant

Matepi mkulu kulumikiza mphamvu, kusintha unsembe ntchito; chakwanira kugwiritsa ntchito mankhwala kumalo zinthu mogwirizana, atolankhani mwamphamvu - ndipo inu wodalirika komanso cholimba, ndipo ambiri Chofunika, kugwirizana zolimba.

Kudzipatula zitsulo denga

Ngati mwaganiza kukonza denga amapangidwa ndi zitsulo, ndi sealant kwa kudzipatula ake ayenera guluu wolimba kwambiri pamalo zitsulo, kupanga kugwedera, mmene mpweya. katundu zimenezi n'zochokera phula zomatira ndi polyurethane. Kugwira nawo ntchito choyamba ayenera kukhala degreased m'munsi wamba zosungunulira.

Zofunika! Kwa zitsulo denga m'gulu siyabwino silikoni - izo amatha oxidizing zitsulo ndi kuyambitsa dzimbiri msanga, amene ali inadmissible mu nkhani iyi.

The kutchinjiriza wa denga la gulu corrugated

zida amatenda denga yopingasa ndi ofukula fixation zakuthupi denga. Pankhaniyi, chabwino zoyenera akiliriki, silikoni ndi polyurethane sealant. Patsogolo ntchito n'kofunika kuti degrease m'munsi ndipo onetsetsani kuti ndi youma - yekha mu nkhani iyi, inu mukhoza kuwerenga pa dzuwa mkulu.
