He Kupu Whakataki ki ngā Āhuatanga ABS me ngā Tikanga Whakarerekētanga

Ko te kapia ABS he copolymer acrylonitrile-butadiene-styrene, ko tētahi o ngā momo kirihou he tino pai te mahi whānui. I tētahi taha, kei te tuwhera haere ngā tono mākete ABS, i tētahi atu taha, nā te whanaketanga o ngā momo hou me te whakarerekētanga hangarau me te rangahau koranu, kei te piki haere te noho hei tuaono nui rawa atu, inā koa nā te whakarerekētanga, kua puta ake ngā momo hou a ABS. Ka taea te whakaranu ki ngā momo kapia hei hanga koranu, he maha ngā momo me ngā tono whānui, ā, ko tētahi o ngā kirihou hangarau matua.

Ngā āhuatanga ā-tinana o te ABS

He kapia maramara, he kapia pīrori rānei te ABS, he kōwhai mārama te tae, kāore he paitini, kāore he reka, he iti te mimiti wai, he pai ngā āhuatanga ā-tinana me ngā āhuatanga ā-mīhini whānui, pērā i te pai o ngā āhuatanga hiko, te ātete kakahu, te pumau o ngā āhuatanga, te ātete matū me te āhua kanapa, me te ngāwari ki te tukatuka. Ko te ngoikoretanga ko te ātete huarere, te ātete wera ngoikore, me te mura.

Pene kiri ABSngā āhuatanga hangarau

He tino pai ngā āhuatanga ā-pūkaha o te ABS, he tino kaha te pānga, ā, ka taea te whakamahi i ngā pāmahana tino iti; he tino pai te ātete kakahu o te ABS, he pai te pumau o ngā āhuatanga, ā, he ātete hinu, ā, ka taea te whakamahi mō ngā peera i raro i te kawenga me te tere reo. Ka pāngia ngā āhuatanga ā-pūkaha o te ABS e te pāmahana.

Te whānuitanga o te tono o te ABS

Ka whakamahia te ABS kanapa teitei mō ngā horoi korehau, ngā pā hiko, ngā hauhautanga, ngā waea me ētahi atu hua taputapu kāinga, ka tutuki mā te whakahaere i te rahi matūriki rapa R+ (iti ake) i roto i te ABS. Ka whakamahia te ABS kanapa iti mō ngā papaaho, ngā taupoki taputapu, ngā pou me ētahi atu wāhanga o roto o te motuka, e whakakīia ana ki ngā whakakī matotoru hei whakaiti i te kanapa o waho, hei whakaiti hoki i te kanapa o waho.

Ngā momo me ngā āhuatanga o te ABS

Ātete ahi (ātete mura) ABS kōeke:

He rauemi mura te ABS, e ai ki te whakaritenga UL94, kei te taumata HB. Ka tere te tineia o te ABS ina mura, ā, ka tukuna he nui o te hau paitini me te paoa pango, kāore e pai mō te whakamahinga mahi. I te whanaketanga o te pūtaiao me te hangarau me te kounga o te oranga, kei te kaha haere te mōhiotanga o te tangata ki te haumaru, ā, ko te whakamahinga o ngā rauemi kirihou i roto i te whare me te whenua, i tāwāhi, kua whakatakotohia he whakaritenga ārai ahi, kua whakawhanakehia ngā whakaritenga hangarau me ngā paerewa e rite ana, nō reira he mea nui te rangahau.
E toru ngā huarahi matua hei whakaiti i te kaha o ngā kapia ABS ki te tinei:

1. Whakamahia ngā pūmua ārai mura hei whakaranu ki te ABS, pērā i te CPE, te PVC;

2. Te whakarerekētanga matū o te ABS o nāianei, pērā i te whai wāhi mai o te styrene tribrominated hei monomer tuawhā hei whakarite i te ABS wāhanga-whā;

3. Mā te huarahi whānui ki te ABS hei whai wāhi atu, tae atu ki ngā aukati mura kore-waro (pērā i te MoO3) me ngā aukati mura waro (pērā i ngā pūhui halogen, ngā aukati mura phosphorus). He pai te pānga aukati mura o te momo aukati mura, engari tera pea ētahi atu āhuatanga he kino (pērā i te koroheketanga, te utu nui). Me whai tukanga whakamahinga motuhake me te tukanga uaua ake te ABS kua whakarerekētia i te matū. Ko te huarahi tuatoru ka whiwhi i te taurite i waenga i te utu me te mahi, ā, he tairongo ake i roto i te hoahoa rauemi maha-mahi. I tēnei wā, ko te whakarerekētanga aukati mura o ngā rauemi ABS e hangai ana ki te tāpiri i ngā aukati mura kei roto i te halogen he tino whai hua.
