Ma teyala amatha kuyendetsa bwino madera - ndi njira yopindulitsa komanso yokongola yokometsera denga.
Zizindikiro za matabwa a dari
Matabwa okhala ndi matabwa amakhala opangidwa ndi chithovu. Njira yotsika mtengo - zopangidwira, zotsindikizidwa, mphamvu ya zinthuzo ndizochepa, makulidwe ndi 6-8 mm. Gawo lapakati limaphatikizapo matayala a jekeseni: makulidwe a 9-14 mm, chiwerengerocho chikuwonekera bwino. Mphamvu zimatheka chifukwa cha kutentha kwakukulu pazinthu. Mtengo wapatali umatengedwa ngati mankhwala ochotsedwa. Pamwamba nthawi zambiri imatsanzira kapangidwe ka nkhuni, marble, miyala. Mphamvu ndizitali, zomwe zimakhudza mtengo.
Pamene mukugula, mukuyenera kuwonjezera 10-15% pocheka ndi kudulira. Zimangosankha zomwe mungasunge mbale yamchere ya polystyrene.
Kodi ndi bwino kuti mumangirire matayala a kudenga?
Kukhazikika pamadzi kumakhala kosavuta kwa thanzi, koma ndi nthawi yayitali kuti iwonongeke, pamene imakhala yayuma nthawi yayitali. Ngati kutentha sikulakwika, pamapeto pake, mabakiteriya ndi bowa akhoza kuyamba.
Zodalirika kwambiri pakukonzekera ndizogwiritsidwa ntchito ndi solvents (zochokera mowa kapena acetone). Iwo ali mofulumira komanso odalirika kwambiri pamwamba pake. Ndikofunika kuganizira zosokoneza zomwe zingatheke pamene mukugwirizana ndi osakaniza.
Adhesives monga "kusungunula" kumapangitsa kuti thupi likhale lolimba pamene likutentha. Izi ndi mankhwala abwino kwa zipinda zomwe nthawi zambiri zimayeretsedwa, chinyezi chawonjezeka, mwachitsanzo, ku khitchini.
Ndi gulu ati amene ali bwino kwa matayala a kudenga? Gulu wothandizira amaonedwa ngati chilengedwe chonse. Epoxy ndi silicone maziko (ali ndi fungo lakuthwa) kutsimikizira kumbali iliyonse. Mu kusinthasintha kozungulira, chisakanizo ndi chachifupi kwambiri. Kuti mugwire ntchito ndi zosakaniza, mukufunikira mfuti, yomwe imakhudza mtengo wa kuikidwa.
Kutsika kochepa, kumangiriza ndi kusakaniza kwa chinyezi kumapangitsa "misomali yamadzi" njira yodziwika yopangira mbale zowonjezera. Sungani kubisala kosalekeza. Kuti mukonze mapepala, mutha kusankha chosakanizidwa chokwanira. Mumagwiritsa ntchito ngati guluu, ndipo imayambanso zigawo.
