Whakamahinga
Ko te Photoinitiator TPO he photoinitiator tino whai hua (1) momo rauropi kore utu e mimiti ana i roto i te awhe roa o te roangaru. Nā te whānui o te awhe mimiti, ko tōna tihi mimiti whai hua ko te 350-400nm, ā, ka mimiti tonu ki te 420nm. He roa ake tōna tihi mimiti i tērā o ngā tīmatanga tuku iho. I muri i te whakamārama, ka taea te whakaputa i ngā rauropi kore utu e rua, te benzoyl me te phosphoryl, ka taea e ēnei te tīmata i te polymerization. Nō reira, he tere te tere o te photocuring. He pānga photobleaching anō hoki tōna, ā, he pai mō te whakamaroke hohonu o te kiriata matotoru me te āhuatanga o te paninga kore-kōwhai. He iti te pikinga, ā, he pai mō ngā pūnaha wai-pūtake.
Ko te nuinga o te wā e whakamahia ana i roto i ngā pūnaha mā, ā, ka taea te whakamahi ki ngā paninga ka taea te whakaora i te UV, ngā waituhi tā, ngā piripiri ka taea te whakaora i te UV, ngā paninga muka whatu, ngā ātete whakaahua, ngā pereti tā photopolymer, ngā kapia stereolithography, ngā rauemi hiato, ngā rauemi whakakī niho, me ētahi atu.
Hei kaiwhakaoho whakaahua, e whakamahia ana i roto i ngā waituhi tā mata, ngā waituhi tā tuhi, ngā waituhi tā flexographic, me ngā paninga rakau. Ka taea te whakamaroke katoa i te TPO ki runga i ngā mata mā, ki ngā mata he nui te tae o te titanium dioxide. He whānui te whakamahinga i roto i ngā paninga maha. Nā ōna āhuatanga mimiti pai, he tino pai mō ngā waituhi tā mata, tā tuhi, waituhi tā flexographic, me ngā paninga rakau. Kāore te paninga e huri kōwhai, he iti te pānga muri-polymerization, ā, kāore he toenga e toe ana. Ka taea hoki te whakamahi i roto i ngā paninga mārama, he tino pai mō ngā hua he iti te hiahia kakara. Ina whakamahia takitahi i roto i ngā polyesters kore-kūkū kei roto ngā pūnaha styrene, he tino teitei te whai huatanga tīmatanga. Mō ngā pūnaha acrylate, inā koa ngā pūnaha tae, me whakamahi tahi me ngā amines, acrylamides rānei. I te wa ano, ka whakakotahihia ki ētahi atu kaiwhakaoho whakaahua kia tino whakamaroke te pūnaha. He tino pai mō te whakamaroke i ngā pūnaha mā iti te kōwhai me ngā paparanga kiriata matotoru. Ka taea te whakapai ake i te pai o te whakamaroke ina whakamahia te photoinitiator TPO me te MOB 240, te CBP 393 rānei. Koinei te whakarewa tango pai rawa atu mō ngā waeine warowaihā kakara hinu, ā, ka whakamahia hoki hei matū whakapūmua i roto i te mara o ngā matū pai.
Te Tākai me te Tukunga
20KG/Pahu, kia rite rānei ki ngā whakaritenga a te kiritaki.
Nō ngā taonga noa, ā, ka taea te tuku mā te moana me te rangi
Te pupuri me te rokiroki
Te roa o te oranga: 24 marama mai i te rā i hangaia ai, i roto i te takai taketake kāore anō kia whakatuwheratia, rongoatia ki te wāhi matao, maroke, ā, kāore e taea te ārai i te rā tika, i te wai rānei.
Whare putunga hauhautanga, Whakamaroke pāmahana iti, Wehea mai i ngā waikura me ngā waikawa.
