Mā ngā mita mātotoru ā-roto, pērā i te mita mātotoru marau whakahāngai Lonnmeter, ka taea te ine tika i roto i te tukanga o ngā hanganga nitrocellulose lacquer kei roto ngā whakarewa pūngao teitei mō te whakamahinga ahumahi. Mā te aroturukitanga mātotoru ā-wā tonu ka mau tonu ngā ōwehenga tika o te whakarewa-ki-te-rēsini, ka pā tika ki te kounga horapa o te tae, te kanapa o te kiriata, me te ōritetanga o te tono. Mō ngā tikanga horapa o te tae i roto i ngā paninga, mā te pupuri i ngā rerekētanga mātotoru i roto i te ±0.5% ka whakarite kia tino pai te makuku o te matūriki, ā, ka ārai i te rerekētanga o te puranga-ki-te puranga.
Ka whakaitihia te mōrearea o te whakakoi i waho o te whakaritenga nā te kore taurite o te whakarewa, te whakakotahitanga rānei o te tae mā te urupare tere. Ko ngā whakarewa kohua nui mō te tukatuka polymer me whakahaere kiato tata kia kore ai e taurite te tere mimiti me te hanganga kiriata kore taurite. Mā ngā raraunga tonu ka taea te whakatika tere—te whakaiti i te mahi anō, te whakapai ake i te hua, me te whakarite kia tutuki i ia puranga ngā whakaritenga kanapa me te rere.
Nitrocellulose Lacquer

Kupu Whakataki
Ka whakawhirinaki te ranu nitrocellulose ki te whakahaere tika i te matotoru kia eke ki te kanapa teitei me te kounga paninga ōrite. Ka aroturuki tika ngā mita matotoru ā-roto, pērā i te mita matotoru marau whakahāngai Lonnmeter, i te inenga wai i te wā e whakaranu ana. Ka pupuri ngā pānui tika i ngā ōwehenga whakarewa-ki-te-reini tino pai, inā koa me ngā whakarewa kohua teitei mō te whakamahinga ahumahi. Ko ngā tikanga horapa tae whai hua—ngā mira pītiti, ngā kaiwhakahora tere-teitei, te cavitation ultrasonic—me whiriwhiri pakari te whakarewa kia mau tonu ai te tae. Mā te whakatikatika wā-tūturu o te matotoru ka puta he āhua ōrite, he hanganga kiriata maeneene, me te kanapa kiriata pai ake mō ngā paninga motuka me ngā tāonga whare. E whakaatu ana ngā rangahau ahumahi ko ngā kiriata angiangi o te ranu nitrocellulose, i hangaia i roto i ngā tukanga maha-paparanga, ka puta he kanapa me te māramatanga pai ake. Ka taea e te ine matotoru ā-roto te whakatika tonu, te whakaiti i te rerekētanga puranga me te tautoko i te whakaputanga nui.
Tirohanga Whānui o te Rere Tukanga
Ka whakaranua e ngā tauhohenga whakahaeretia te nitrocellulose me ngā whakarewa kohua teitei mō ngā whakamahinga ahumahi, pērā i te butyl glycol me te dibutyl phthalate. Ka whakauruhia ngā tāpiringa me ngā mea hanga kirihou hei whakarei ake i te ngāwari me te kanapa. He mea nui ngā ōwehenga whakarewa; ka whakarewahia e ngā whakarewa tūturu te nitrocellulose, ko ngā whakarewa tahi me ngā mea kāore i te whakarewa ka whakatikatika i te matotoru me te mutunga o te mata.
Ko ngā tikanga whakamarara tae mō te peita me ngā paninga ko ngā kaiwhakarara tere-teitei, ngā mira pītiti, me te cavitation ultrasonic. Mā ēnei ka whakarite kia ōrite te utaina o te tae, ka ārai i te kohikohi me te tautoko i te pumau o te kiriata. Mā te whakamarara tae kua arotauhia ka whakapai ake i te kanapa o te kiriata i roto i ngā tono peita me te ōrite o te hipoki.
Mā te whakarerekē i te kukū o te whakarewa ka tino whakahaerehia te matotoru me te mātotoru. Ka whakaratohia e ngā mita mātotoru mō te ine i te wai, tae atu ki te mita mātotoru o te marau whakahāngai Lonnmeter, ngā uara wā-tūturu i te wā e whakaranua ana, kia pai ai te rere me te kanapa o te otinga.
Ka aromatawaihia te hanganga kiriata i roto i te raina mō te kanapa, te piri, me te kapi, mā te whakamahi i ngā taputapu ine kua whakauruhia ki roto i ngā raina tukanga. Ka tiakina te hanganga whakamutunga o te ranu nitrocellulose me ana whakamahinga mā te whakawhiti mā roto i ngā paipa kua whakauruhia ki ngā mita kiato raina mō ngā paninga kanapa teitei me te ranu nitrocellulose. Mā tēnei ka puta he kounga ōrite mai i te puranga ki te puranga.

Ngā Wero i roto i te Ine i te Kiato ā-Rāina
Ka whakaroa te mimiti o ngā whakarewa kohua teitei, ka puta he rerekētanga tere o te tohu matotoru i te wā e hangaia ana te raikara nitrocellulose. Ko ngā raina ahumahi e whakamahi ana i ngā whakarewa he kohua teitei ake i te 140°C (hei tauira, te xylene, te butyl acetate) ka whakaatu i te rerekētanga matotoru tae atu ki te 6% ia hāora nā ngā huringa o te hau, te wera, me te tere rere.
Ko ngā tikanga horapa o ngā tae pēnei i te mira pītiti me te cavitation ultrasonic ka tūtaki ki te whakaeminga iti; ka huri te utaina kore taurite i te kounga o te kanapa, ka puta he rerekētanga 3–15% o te āhua o te kiriata. Ki te kore he aroturukitanga wā-tūturu, kāore e kitea te taunga o te tae me te hanganga tautau, ka pā tika ki ngā paninga kanapa teitei.
I te wā e piki haere ana te tauine, he uaua te pupuri i te horapa ōrite me te kore he mita kukū ā-roto. Ka whakanui ake ngā mīhini whakaranu rere i te putanga engari ka whakanui ake i te mōrearea o te kore taurite o te puranga ina huri te kōwhiringa whakarewa, te kaha whakaoho rānei. Kāore ngā mita kiato taiwhanga tuku iho—te ine pūngao, te pauna wai rānei—e hono atu ki ngā nekehanga kiato wai tukanga wā-tūturu, inā koa i roto i ngā rere hihiri.
Ka heke te tika o ngā raraunga i ngā aukatinga tukanga, te paru o ngā taputapu, me te puranga toenga ki ngā mata o te pūoko. Me whakatika aunoa; ka whakaroahia te urupare e ngā pānui ā-ringa tae atu ki te 90 meneti mō ia puranga, ka hua ake he hanganga me ngā whakamahinga o te nitrocellulose lacquer kāore i te tino tika.
Ngā Painga o te Whakauru i ngā Mita Kiato Ā-Rāina/Ngā Mita Kukū Ā-Rāina
Mā ngā mita kukū me te matotoru ā-roto e whakahaere tika ana i te ōwehenga whakarewa-ki-te-reini mō te peita nitrocellulose. Mā tēnei raraunga tika, tere tonu ka whakarite kia tino pai te horapa o te tae, ā, ka ārai i te rere o te kanapa i puta mai i te kore taurite o te tae—he mea nui ina hangaia me ngā wairewa kohua teitei mō te whakamahinga ahumahi. Mā te ine ā-roto ka whakakorea ngā whakaroa mai i te tauira ā-ringa, e puta ai ngā mōrearea nui i waho o te whakaritenga i roto i ngā tikanga horapa tae mō te peita me ngā paninga.
Ka whakaratohia e te mita mātotoru marau whakahāngai Lonnmeter he ine tika i roto i te raina 24/7, ka tangohia te whakawhirinaki ki te manatoko taiwhanga ā-wā. Ka aukatihia e ngā pānui mātotoru tonu ngā puranga kore e tutuki i mua i te haere tonu ki te whakakī—he mea nui mō ngā paninga kanapa teitei me te lak nitrocellulose me te tukatuka polymer e whakawhirinaki ana ki te kukū whakarewa tika.
Mā te aroturuki tonu ka taea te whakarerekē tere i te kōwhiringa whakarewa mō te horapa o te tae hei whakautu ki te rerekētanga o te tukanga i te wā tūturu. Mā tēnei ka oati te ōritetanga o te puranga-ki-te-puranga, te whakahaere kanapa pakari, me te hanganga kiriata ōrite ahakoa i roto i ngā oma nui.
Tonoa he utu mō te mita mātotoru ā-roto Lonnmeter hei whakahaere i te hanganga o te ranu nitrocellulose. Whakatutukihia te whakatikatika tika o ngā whakarewa kohua teitei mō te whakamahinga ahumahi, kia mau tonu ngā tikanga tohatoha tae tino pai mō te peita me ngā paninga, me te whakanui ake i te kanapa me ngā paninga kanapa teitei e hangai ana ki te ranu nitrocellulose.
