Clay Chitsulo: zoyimira ndi malamulo ntchito

Pafupifupi zomatira uliwonse chifukwa zitsulo, amene angapezeke mu masitolo, ali mphamvu yapamwamba. Nthawi zambiri adherend dongosolo n'kugwa mkati zomatira wosanjikiza, ndi connectable pa malire a zitsulo. Choncho, mphamvu ya zomatira chomangira makamaka zimadalira kukonzekera pamwamba.

Kawirikawiri ❖ kuyanika ndi zakhudzana ndi mafuta zosiyanasiyana, mphero lonse, zatsalira utoto, kuda dzimbiri. Kuthetsa zonse izi zimakhala mankhwala ndi umakaniko.

Pamaso ntchito zomatira chifukwa zitsulo zakhudzana pamwamba woyesedwa ndi vutolo zidulo kapena alkalis, ndi nyimbo yapadera chifukwa kuchotsa dzimbiri ndi kuyeretsedwa. The kanthu zidulo kapena alkalis zachokera chakuti oxides anawonongedwa mofulumira kuposa m'munsi. Kukonza ndi reagents mankhwala uli wachangu ndi mtengo kwambiri kuposa Machining. Komanso anapanga padziko chitsulo kugonjetsedwa wosanjikiza, amene kumawonjezera mphamvu ndi durability ya zomatira muzikondana.

Lopangidwa kuyeretsa padziko lapansi anachita pamaso ntchito zomatira chifukwa zitsulo. Pankhaniyi zokolola mankhwala ntchito abrasives (waya maburashi, kuwombera kabotolo makhazikitsidwe, sandblasting kapena sandpaper). Pamwamba chifukwa amakhala rougher, amene kumawonjezera m'dera zimachitika choncho zitsulo zomatira kumawonjezera chomangira mphamvu.

Today kumsika amapereka zosiyanasiyana zomatira chifukwa zitsulo, amene makhalidwe awo ndi zikuchokera.

zakuthupi chimodzi ndi polyvinyl nthochi zomatira (PVA). Timatha ntchito ndi matabwa, galasi, chitsulo, zikopa, nsalu ndi ena. Thunthu The umagwiritsidwa ntchito wosanjikiza woonda Pre-degreased kali kuti mwamphamvu wothinikizidwa. zomatira timagwira zikadzatha mphindi 20, wathunthu kuyanika zimawonedwa Patapita tsiku.

Iwo ankati ndi amenewa kudziwika zomatira chifukwa zitsulo ndi mphira, monga "kamphindi". Komanso akhoza kuphatikiza nkhuni, ziwiya zadothi, pulasitiki, anamva, molimba PVC, etc. Nkhanizi ndi poizoni ndi flammable. Ndi izo ziyenera kugwirira ntchito kokha m'madera bwino mpweya wokwanira kapena lotseguka, kuchokera magwero a poyatsira. Njira ntchito enaake anayesa padziko okonzeka, analoledwa kuima Mphindi khumi ndi zisanu, kenako compress zipangizo mating masekondi angapo.

Pafupifupi aliyense akudziwa za zomatira epoxy, amene akulola kugwirizana zitsulo, galasi, matabwa ndi zina zipangizo. Komanso njira ntchito ming'alu ndi mabowo akusindikiza, zikhoza kugwiritsidwa ntchito ngati ❖ kuyanika lacquer.

Izi zitsulo zomatira ali mafuta ndi madzi kukana, ndipo akutumikira monga insulator wabwino. thunthu ndi poizoni. Pambuyo kukhudzana ndi khungu, m'pofunika yomweyo muzimutsuka ndi madzi ofunda ndi sopo. Njira sangathe ntchito kulumikiza katundu chakudya. Self zomatira kukonzekera ntchito utomoni Amatipatsa ndi hardener mu chiŵerengero cha 10 1. oyambitsa kwa mphindi 10, yankho iyenera kugwiritsidwa ntchito padziko wosanjikiza wochepa thupi, ndiye kulumikiza iwo. Tsankho njira polymerization kumachitika mwa ola 4 wathunthu solidification amapezeka mkati mwa masiku.
