Parenga te waikura

hua Metal i runga i te wā hipoki māmālie ki te ƒpüata≈ hoki faaiti. Construction huna tata tahuri ki te puehu. Ki te karo i taua hua meapango, me mohio koutou ki ta te waikura o konganuku ki a pehea te tiaki i ki reira. i raro Konganuku te ki kinonga tika ki te rongo ki te taiao o waho, i te mea electrochemically matū ranei. puta waikura Chemical i roto i te pāpāho e kore e ahei o te whakahaere i te nāianei hiko (hinu, hau, waiwaihā). I whai wāhi ia ki te tino konganuku katoa. waikura iahiko puta tika ki takanga o kiriata whakarewa -hiko tika ki awe taiao. I roto i ngā, whakamahia te tote whare pānga-hangarau i runga i te rori i roto i te hotoke, me ngā kotiti. Ara me ngā tikanga e ai hanga i te waikura te, i reira e maha.

Ko te tino rongonui, me te whānui ko te whakamahi o coatings. haere mai ratou i roto i te maitai me te kohuke kore-konganuku. miramira nui whakarato coatings e hāngai ana te hanga teka waerau waihanga. Pararopi paninga kore-konganuku ko he momo nui. Ēnei ngā peita (hinu, alkyd me te tohu) me varnishes (rakau uku, uku waihanga). A, no te tono i te taua tiaki te waikura hanga he kiriata angiangi karapotia te whakarewa i te houku me te pānga taiao. He tino ngāwari ki te tono, utu peita me varnishes. I te timatanga o te mahi ko te mea e tika ana ki te tino whai i te hangarau o ratou tono. he tika i roto i te maha o ngā paparanga Cover o te mata whakarewa ki te pai te tiaki i ngā hanganga i mana kōhauhau.

coatings konganuku inhibitors wehewehe rua momo. Ko te paninga tusia tuatahi ngā cadmium, konutea, te konumohe. Ko te tuarua - waikura-ātete paninga o parahi, te hiriwa, mata, te konukōreko, me te chromium.

Runga anō i te āhua o te huarahi Kua tiaki te waikura, huaina mahi te mea te pitoiho pitoake ranei. He coatings whakarewa, inhibitors ki electronegativity nui, me coatings he electropositive nui. no pitoake coatings ki te momo tuatahi, te pitoiho - ki te tuarua. Ko te whakamahi o te konumohe, me te konutea, rite pitoiho rite coatings pitoake - konukōreko, parahi, he tine.

tikanga Various o te tiaki whakarewa ki te waikura, me te whai wāhi te maha o taatou paninga. Hei tauira, whakamahia hoki te tono o inhibitors matū te he tikanga mō te pani hanganga konganuku atu konganuku: konumohe, konutea.

Ki te mea kua waikuratia te hanganga whakarewa, na te āwhina pōturi te whakangaromanga o passivating tāpiritanga me inhibitors. Whai wāhi ki te inhibition o tukanga waikura i roto i te kawakore me taiao kūpapa pērā hāora kaha rite kawakore whenua me konganuku alkali. Hei tiaki i te ngā i roto i te raima whakapakaritia, whakamahia konupūmā pākawa-nitrite.

A, no te hiahia koe te tiaki i te waikura, e puta ana i raro i te mana o te taiao o waho, me te rerenga kōhauhau, te whakamahi i inhibitors muia, e he rauemi e adsorb ki te mata whakarewa i rangi whātatahia runga ki te hanga i te kahupapa ranei.
