Te tukanga whakamaoritanga whakapiri

Tikanga whakaora:

Ko te rongoa o nga piripiri ka mahia e nga tikanga a-tinana, penei i te whakaetonga o nga whakarewa, te whakakotahitanga whakaehunga me te whakamahana rewa, me nga tikanga matū.

• (1) Te whakapiri werawera: Ka rewa te polymer ma te whakamatao i muri i te whakamakuku i te mata kia herea.

(2) Te whakapiri o te otinga: I te mea ka whakaeto te whakarewa, ka piki te kukū o te otinga, ka pakari haere, ka whai kaha.

(3) Whakapiri whakaehunga: I te mea ka kuhu haere te wai i roto i te whakaehunga ki roto i te porous adhered me te whakaeto, kei te piki haere tonu te kukū o te whakaehunga, a, i te mutunga mai na te awangawanga o te mata, ka whakapoapoa nga matūriki colloidal polymer. A, no te tiketike o te pāmahana ambient, te whakaehunga condenses ki te kiriata whakapiri tonu, i te mea ka iti te pāmahana ambient me te iti rawa kiriata hanga pāmahana (MFT), he ma i hanga he kiriata whakapiri korekore. Ko nga whakapiri whakaehunga ko te polyvinyl acetate te nuinga me ona copolymers me te copolymers waikawa kiriaku.

(4) Adhesives Thermosetting Ko nga monomers multifunctional, prepolymers ranei o te kapia thermosetting ka whai tauhohenga polymerization. I te pikinga o te taumaha o te ngota, ka huri nga mekameka ngota, ka whiti-honohono, ka hanga he rea kore e rewa, he whakakoi taketake ranei. Ko te whakaroa i te wa rongoa me te whakanui ake i te pāmahana whakaora i roto i tetahi awhe kaore i te rite, me te whakaheke i te pāmahana whakaora he uaua ki te utu ma te whakaroa i te waa. Na te mea me puta he tauhohenga matū i waenga i te whakapiri me te mata o te piri, me tino nui te pāmahana kia haere tonu.

Te pehanga whakaora:

He painga mo te whakapiri ki te whakauru katoa ki te mata; he pai mo te tango i nga mea iti ngota ngota i puta mai i te tauhohenga whakaora whakapiri; he pai mo te tango i nga whakarewa wariu e toe ana ki te paparanga piri; he pai mo te whakahaere i te matotoru o te paparanga whakapiri; ko nga whakapiringa me te pokey teitei he maha nga paparanga whakapiri matotoru, a ko te whakatikatika o te pehanga whakaora ka whakahaere i te awhe matotoru o te paparanga whakapiri.

Whai muri i te whakapiri i te kāpia, waiho kia noho mo tetahi wa, e kiia nei ko te pre-curing. Ka piki ake te pokey o te kāpia, whakamahia te pehanga hei whakarite i te riterite o te matotoru o te paparanga kāpia.

Te pāmahana whakaora:

Mēnā he iti rawa te pāmahana whakaora, he iti rawa te whiti-honohono kiato o te paparanga whakapiri, ā, kāore i te oti te tauhohenga whakaora; ki te mea he tiketike rawa te pāmahana whakaora, he ngawari ki te ngaro te kapia, ki te hanga ranei i te paparanga piri kia pakarukaru, ka heke te kaha o te hono. He pai te whakamahana ki te tiritiri o nga ngota ngota i waenga i te whakapiri me nga wahanga here, ka taea te hanga hononga matū.

(1) Tikanga whakawera tika i roto i te oumu: Whakamahia he taputapu pupuhi hau hei whakarite kia rite te whakawhiti wera.

(2) Tikanga whakawera o waho: Ka tere te whakawhiti i te wera ki roto o te paparanga whakapiri, ka tino whakapoto te wa whakaora. Tikanga whakawera Ultrasonic: He mea pai mo te whakamaarama wera o nga adhesives viscoelastic me te whakarewa-whakapiri kore utu, engari kaore e pai mo te whakamaarama i nga apiti maataki.
