Kupu Whakataki: Te tukanga hanga ongā hua kirihouKo te nuinga o ngā tukanga matua e whā: te hanga pokepokea ai, te maimoatanga mata, te tā, me te huihuinga. He wāhanga nui te maimoatanga mata. Hei whakapai ake i te kaha piri o te paninga me te whakarato i tētahi turanga kawe pai mō te whakakikorua, he mea nui te tukanga maimoatanga-mua.
Te maimoatanga mata o ngā hua kirihou
Ko te nuinga o ngā mahi ko te paninga me te paninga. I te nuinga o te wā, he nui te tioata o ngā kirihou, he iti te polarity, kāore rānei he polarity, ā, he iti te kaha o te mata, ka pā ki te piri o te paninga. Nā te mea he ārai kore-arataki te kirihou, kāore e taea te pani tika ki te mata kirihou e ai ki ngā whakaritenga whānui o te tukanga paninga hiko. Nō reira, i mua i te paninga o te mata, me mahi te paninga o mua hei whakapai ake i te kaha piri o te paninga me te whakarato i te paparanga raro arataki me te kaha piri pai mō te paninga.
Te maimoatanga o mua o te paninga
Ko te maimoatanga o mua ko te tango hinu i te mata kirihou, arā, te horoi i te hinu me te matū tuku i runga i te mata, me te whakahohe i te mata kirihou, kia pai ake ai te piri o te paninga.
1, Te tango hinu
Te whakakore hinungā hua kirihou. He rite ki te tango hinu i ngā hua whakarewa, ka taea te tango hinu i ngā hua kirihou mā te horoi ki ngā whakarewa waro, ki te tango hinu rānei ki ngā wairewa wai kawakore kei roto ngā matū horoi. He pai te tango hinu ki ngā whakarewa waro mō te horoi i te parafini, te ware pi, te ngako me ētahi atu paru waro mai i te mata kirihou. Kaua te whakarewa waro e whakamahia e memeha, e pupuhi, e pakaru rānei i te kirihou, ā, he iti te pāmahana kohua, he pūngāwerewere, kāore e paitini, ā, kāore e mura. He pai ngā wairewa wai kawakore mō te tango hinu i ngā kirihou ātete-kawakore. Kei roto i te wairewa he houra tunutunu, he tote kawakore me ngā momo matū horoi. Ko te matū horoi e whakamahia whānuitia ana ko te raupapa OP, arā, ko te alkylphenol polyoxyethylene ether, kāore e hanga pahuka, ā, kāore e noho ki te mata kirihou.
2、Whakahohenga mata
Ko te mahi whakahohenga nei he whakapai ake i ngā āhuatanga o te mata o ngā kirihou, arā, he whakaputa i ētahi rōpū porotaka ki runga i te mata kirihou, he whakararuraru rānei kia māmā ake ai te whakamakuku me te mimiti o te paninga ki runga i te mata o te mea mahi. He maha ngā tikanga mō te maimoatanga whakahohenga mata, pērā i te whakahāngai matū, te whakahāngai mura, te whakairo kohu whakarewa me te whakahāngai tukunga korona. Ko te mea e whakamahia whānuitia ana ko te maimoatanga whakahāngai tioata matū, e whakamahi pinepine ana i te wai maimoatanga waikawa chromic, ā, ko tōna tauira noa ko te 4.5% pāhare pākawa dichromate, 8.0% wai, me te 87.5% waikawa whanariki kukū (neke atu i te 96%).
Ka taea te pani tika i ētahi hua kirihou, pērā i te polystyrene me ngā kirihou ABS, me te kore e whakamahia he maimoatanga waikura matū. Hei whiwhi i te paninga kounga teitei, ka whakamahia hoki te maimoatanga waikura matū. Hei tauira, i muri i te tango hinu, ka taea te keri i te kirihou ABS ki te wai maimoatanga waikawa chromic waimeha. Ko tōna tauira maimoatanga noa ko te 420g/L waikawa chromic me te 200ml/L waikawa whanariki (taumaha motuhake 1.83). Ko te tukanga maimoatanga noa ko te 65℃70℃/5min10min, te horoi wai, me te whakamaroke. Ko te painga o te keri ki te wai maimoatanga waikawa chromic ahakoa te uaua o te āhua o te hua kirihou, ka taea te tukatuka kia ōrite. Ko te ngoikoretanga ko te mahi he morearea, ā, he raruraru parahanga.
Te maimoatanga o mua o te paninga paninga
Ko te kaupapa o te maimoatanga o mua i te paninga paninga he whakapai ake i te piri o te paninga ki te mata kirihou, me te hanga i tētahi paparanga raro whakarewa kawe hiko ki runga i te mata kirihou. Ko te tukanga maimoatanga matua ko: te whakakorikori ā-ringa, te tango hinu matū, te whakakorikori matū, te maimoatanga whakaōrite, te maimoatanga whakahohe, te maimoatanga whakaiti me te whakakikorua matū. Ko ngā mea tuatahi e toru he whakapai ake i te piri o te paninga, ā, ko ngā mea whakamutunga e whā he hanga i tētahi paparanga raro whakarewa kawe hiko.
1, Te whakakorikori ā-ringa me te whakakorikori matū
Ko te whakakorikori ā-ringa me te maimoatanga whakakorikori matū he mea hei whakakorikori i te mata kirihou mā ngā tikanga ā-ringa me ngā tikanga matū hei whakanui ake i te horahanga pa i waenga i te paninga me te papa. E whakaponohia whānuitia ana ko te kaha piri ka taea te whakatutuki mā te whakakorikori ā-ringa he tata ki te 10% noa iho o te kaha o te whakakorikori matū.
2, Te tango hinu matū
He rite tonu te tikanga tango hinu mō te maimoatanga o mua i te paninga mata kirihou ki te tikanga tango hinu mō te maimoatanga o mua i te paninga.
3、Te Whakaohooho
Ko te whakahāngaitanga he mimiti i ētahi matū ngāwari te waikura, pērā i te tine dichloride, te titanium trichloride, me ētahi atu, ki runga i te mata o ngā kirihou he kaha te mimiti. Ka waikurahia ēnei matū ngāwari te waikura i te wā e whakahohehia ana, ā, ka whakaitihia te kaiwhakaoho hei karihi tioata whakakorikori, ka noho tonu ki runga i te mata o te hua. Ko te mahi a te whakahāngaitanga he whakatakoto i te turanga mō te paparanga whakarewa whakakikorua matū e whai ake nei.
4、Whakahohenga
Ko te whakahohenga he rongoā i te mata kua pāngia e te mate mā te whakamahi i tētahi otinga o ngā matū whakarewa kaha-whakakorikori. Ko tōna kaupapa matua he tuku i te hua kua mimitia ki te matū whakaiti ki roto i tētahi otinga wai kei roto he waikura o te tote whakarewa utu nui, kia whakaitihia ai ngā katote whakarewa utu nui e te S2+n hei waikura, ā, ka whakatakotoria te whakarewa utu nui kua whakaitihia ki runga i te mata o te hua hei matūriki colloidal, he kaha te kaha whakakorikori. Ina tukuna tēnei mata ki roto i tētahi otinga whakakikorua matū, ka huri ēnei matūriki hei pokapū whakakorikori, ka tere ake te tere tauhohenga o te whakakikorua matū.
5, Maimoatanga whakaiti
I mua i te whakakikoruatanga matū, ka rumakina ngā hua kua whakahohehia, kua horoia ki te wai ma ki roto i tētahi kukū o te otinga whakaiti e whakamahia ana i roto i te whakakikoruatanga matū hei whakaiti me te tango i te whakahohe kāore i horoia. Ka kiia tēnei ko te maimoatanga whakaiti. Ina whakakikoruatia te parahi matū, ka whakamahia te otinga formaldehyde mō te maimoatanga whakaiti, ā, ina whakakikoruatia te nikara matū, ka whakamahia te otinga konutai hypophosphite mō te maimoatanga whakaiti.
6, Whakakikorua matū
Ko te kaupapa o te whakakikorua matū he hanga i tētahi kiriata whakarewa hiko ki runga i te mata o ngā hua kirihou hei waihanga i ngā āhuatanga mō te whakakikorua hiko i te paparanga whakarewa o ngā hua kirihou. Nō reira, ko te whakakikorua matū he taahiraa matua i roto i te whakakikorua hiko kirihou.
