Ngā Pūrongo - Ngā āhuatanga o te paninga rapa kua whakamāotaotia me tōna whakamahinga i roto i te paninga taumaha ārai-waikura

paninga rapa kua whakakōkōhia ki te hau

I te whakapai tonu i te taumata ōhanga o Haina, kei te tere haere te whanaketanga o te umanga mīhini, ā, ko te mara o ngā rauemi ārai-pirau e tika ana mō te umanga mīhini kua arahi i te wā tino whanaketanga. He maha ngā hua ārai-waikura kounga teitei, matatau hoki kua tīmata ki te tuku ki te mākete. Kua mōhiotia te paninga rapa chlorine e te nuinga o ngā kaiwhakamahi mō tōna mahi tino pai, ā, e tū ana i roto i te whakataetae nui o te mākete. Mai i te tekau tau atu i 1960, kua whakamahia whānuitia ngā paninga rapa chlorine i roto i te hanga kaipuke, i ngā ipu, i ngā whare tiaki wai, i te hanga hinu me te hiko hei paninga tautoko mō te pirau niho, ā, he mahi nui tā rātou i roto i te tukanga whanaketanga ōhanga.
E whakaatu ana ngā raraunga e tika ana, e rua ki te toru ōrau noa iho o te mākete paninga ārai-waikura katoa ngā paninga rapa kōrohinu. He tokomaha ngā kaiwhakamahi kāore i te tino mārama ki ngā paninga ārai-waikura rapa kōrohinu, inā koa he iti noa ngā kaihanga hei whai i ngā painga ōhanga, me ētahi atu matū kōrohinu iti te utu hei whakakapi i ngā wāhanga noa o ngā paninga rapa kōrohinu, ka whakararuraru i te mākete, engari i pā hoki ki te whanaketanga o ngā paninga rapa kōrohinu. Hei whakapai ake i te māramatanga o te nuinga o ngā kaiwhakamahi paninga ārai-waikura o te paninga rapa kōrohinu, hei whakatairanga i te whakatairanga me te tono o te paninga rapa kōrohinu, me te whakapai ake i te taumata whanaketanga o te umanga paninga o Haina, inaianei kua whakauruhia e te kaituhi i runga i te rangahau roa, ngā āhuatanga taketake o te paninga rapa kōrohinu, te whakarōpūtanga, te tono me ētahi atu ihirangi, me te tumanako ka āwhina i te nuinga o ngā kaiwhakamahi paninga ārai-waikura.

He tirohanga whānui mō te paninga rapa kua whakamāotaotia

Ko te paninga rapa kōkōwai he mea hanga ki te kapia rapa kōkōwai i hangaia mai i te rapa tūturu, i te rapa hangai rānei hei rauemi mata hei kapia matrix, kātahi ka tāpirihia ki ngā rauemi āwhina me ngā whakarewa e rite ana. He nui te mātotoru o te kapia rapa kōkōwai, kāore he hononga irahiko e kitea ana, he hanganga ōrite, ā, he tino pumau. Mai i te tirohanga āhua, he paura mā te kapia rapa kōkōwai, he kore paitini, he kore reka, kāore he riri. Ka taea te whakamahi ngāwari i ngā paninga rapa kōkōwai, me te whānuitanga o ngā tono, ā, ka taea te whakamahi me ngā momo tae hei paninga tuatahi, hei peita waenga, hei peita o runga rānei. I roto i ēnei, ko te mea e whakamahia ana ko te paninga o runga hei taurite i ngā paninga. Mā te whakarerekē i te kapia rapa kōkōwai me ētahi atu kapia, ka taea te whiwhi, te whakapai ake rānei i ngā momo āhuatanga hei whakatutuki i te pānga paninga nui ake.

ngā āhuatanga o te paninga rapa kua whakamāotaotia

1. Ngā painga o te peita rapa kua whakamāotaotia

1.1 He ātete pai ki te rangi me te pāmahana
I muri i te hanganga o te paninga rapa kua whakakōkōhia ki te hau, ka piri pūmau ngā hononga ngota o te kapia i roto i te paparanga peita, ā, he tino pumau te hanganga ngota. Nā tēnei take, he pai te ātete o te paparanga peita kapia rapa kua whakakōkōhia ki te huarere, ā, he tino ātete ki te wai, ki te waikawa, ki te kawakore, ki te tote, ki te ozone me ētahi atu mea. Ko te urunga o te wai me te hau he tekau ōrau noa iho i tērā o ngā matū alkyd. Mai i te tirohanga o ngā tau maha o te whakamahinga, he kaha te ātete o te paparanga peita rapa kua whakakōkōhia ki ngā whakarewa aliphatic, te hinu parakore me te hinu whakahinuhinu, ā, ka taea te whakamahi hei rongoā ārai-pokepoke i roto i ngā taiao makuku, ā, he tino pai ake te ātete ki te tango cathode.
1.2 He pai te piri, he pai te hototahi ki ētahi atu momo paninga
He nui te piri o te paninga rapa matomato hei paninga tuatahi ki te rauemi maitai. Hei peita o runga, ka taea te whakamahi i te peita waenga me te kapia epoxy, te polyurethane me ētahi atu momo paninga tuatahi, he tino teitei te pānga. He ngawari te whakatika i te paninga rapa chlorine, ka taea e koe te whakamahi i te paninga rapa chlorine hei peita anō, ka taea hoki e koe te whakamahi i te kiriaku, ngā paninga whakarewa me ngā momo paninga ārai-paru katoa hei whakatika i te paraihe.
1.3 Hanganga māmā, watea hoki
He paninga wāhanga kotahi te paninga rapa kōkōwai, he poto rawa te wā hanga kiriata, he tere hoki te hanga. He whānui ngā whakaritenga mō te pāmahana hanga o te paninga rapa kōkōwai, ā, ka taea te hanga mai i te -5 nekehanga ki te 40 nekehanga i runga ake i te kore. He iti rawa te nui o te waiwhakarewa i tāpirihia i te wā hanga, ā, kāore e taea te tāpiri i tētahi waiwhakarewa, ka whakaiti i te mimiti o ngā whakarewa waro, ā, he pai te mahi taiao. Ka taea te pani tika i te paninga rapa kōkōwai ki te mata o ngā wāhanga raima, ā, he pai te ātete ki te kawakore. Ina whakamahia i roto i ngā mahi raina huihuinga, ka taea te whakamahi i te tikanga "māku ki te māku" mō te rehu, ka tino whakapai ake i te pai o te whakaputa.

2. Ngā ngoikoretanga me ngā ngoikoretanga o te paninga rapa kua whakamāotaotia

2.1 He pango te tae o te paninga rapa kua whakakīia ki te hauota, he kanapa iti, he ngāwari ki te mimiti i te puehu, kāore e roa te tae, kāore e taea te whakamahi mō te peita whakapaipai;
2.2 He tino tairongo te ātete wera o te paninga ki te wai. I ngā taiao makuku, ka tino heke te ātete wera. Ko te pāmahana pirau wera i te taiao maroke he 130°C, ā, ko te pāmahana pirau wera i te taiao makuku he 60°C noa iho, ka hua ake he taiao whakamahinga iti o te paninga rapa chlorine, ā, kāore e taea te neke ake i te 70°C te pāmahana whakamahinga mōrahi o te taiao.
2.3 He iti te ihirangi totoka o te peita rapa chlorine, ā, he angiangi te matotoru o te kiriata. Hei whakarite i te matotoru o te kiriata, me rehu tonu, ka pā ki te whai huatanga o te whakaputanga;
2.4 Kāore e taea e te paninga rapa chlorine te ātete ki ngā mea kakara me ētahi momo whakarewa. Kāore e taea te whakamahi i te paninga rapa chlorine hei paninga tiaki pakitara o roto i ngā taiao kei reira pea ngā matū kāore e ātete ki te hau, pērā i te paipa matū, ngā taputapu whakaputa me ngā tāke rokiroki. I taua wā anō, kāore e taea te whakamahi roa i te paninga rapa chlorine ki ngā ngako kararehe me ngā ngako huawhenua;

te ahunga whanaketanga o te paninga rapa kua whakamāotaotia

1. Rangahau mō te ngāwari o te kiriata peita Ko ngā paninga rapa hauota e whakamahia ana mō te maimoatanga ārai-waikura o ngā hua whakarewa.

I te mea ka tino rerekē te rahinga o ngā hua whakarewa ina rerekē te pāmahana, kia kore ai e tino pāngia te kounga o te kiriata peita ina whānui, ina whakawhāiti hoki te papa, me pai te ngāwari o te paninga rapa whai kōroine hei whakaiti i te ahotea e puta mai ana ina whānui rawa te papa. I tēnei wā, ko te tikanga matua hei whakapai ake i te ngāwari o te peita rapa whai kōroine ko te tāpiri i te paraffin whai kōroine. Mai i ngā raraunga whakamātautau, ina tae te nui katoa o te paraffin whai kōroine ki te 20% o te kapia rapa whai kōroine, ka taea e te ngāwari o te kiriata te tae ki te 1 ~ 2mm.

2. Rangahau mō te hangarau whakarerekētanga
Hei whakapai ake i ngā āhuatanga o te kiriata peita me te whakawhānui ake i te whānuitanga o ngā paninga rapa chlorine, he maha ngā rangahau whakarerekētanga kua mahia e ngā kairangahau ki ngā paninga rapa chlorine. Mā te whakamahi i te rapa chlorine me te alkyd, te epoxy ester, te epoxy, te waro tar pitch, te waikawa acrylic thermoplastic me te vinyl acetate copolymer resin, kua kitea te ahunga whakamua o te paninga hiato i roto i te ngāwari o te kiriata peita, te ātete ki te huarere me te ātete ki te waikura, ā, kua whakatairanga i te whanaketanga o te umanga paninga tiaki waikura taumaha.

3. He rangahau mō te ihirangi totoka o ngā paninga
He iti te ihirangi totoka o te paninga rapa kōroine, ā, he angiangi te matotoru o te kiriata, nō reira, kia tutuki ai ngā whakaritenga o te matotoru o te kiriata, me whakanui ake te maha o ngā wā paraihe, kia pā ki te whai huatanga o te whakaputanga. Hei whakaoti i tēnei raruraru, me tīmata mai i te pūtake, me te whakapai ake i te ihirangi totoka o te peita. Nā te mea he uaua ki te whakamakuku i ngā paninga rapa kōroine, ka taea anake te whakaiti i te ihirangi totoka kia pai ai te mahi hanga. I tēnei wā, ko te ihirangi totoka o ngā paninga rapa kōroine kei waenga i te 35% me te 49%, ā, he teitei te ihirangi whakarewa, e pā ana ki te mahi taiao o ngā paninga.

Ko ngā tikanga matua hei whakapai ake i te ihirangi totoka o ngā paninga rapa whai kōrote ko te whakarerekē i te wā whakauru hau kōrote me te whakahaere i te pāmahana tauhohenga i te wā e whakaputa ana i te kapia rapa whai kōrote.
