He aha te PBT, ā, he aha i tino whakamahia whānuitia ai?
Ko te Polybutylene Terephthalate (PBT) he kirihou wera hangarau mahi-teitei i hangaia mai i te butylene glycol me te waikawa terephthalic, he rite ōna āhuatanga ki te Polyethylene Terephthalate (PET). Hei mema o te whānau polyester, e whakamahia whānuitia ana te PBT i roto i ngā motuka, ngā hikohiko, me ngā wāhanga tino tika nā ōna āhuatanga miihini kaha, tōna pumau wera pai, tōna whakamarumaru hiko, tōna ātete ki ngā matū, me tōna makuku. Nā ēnei painga ka waiho hei rauemi pai mō ngā hononga, ngā whare, me ngā whakapaipai o roto.
He aha ngā take mata o te PBT e piki haere ana te āwangawanga i roto i ngā tono ahumahi utu nui?
I te mea kei te whakapiki ake ngā ahumahi pēnei i te motuka, te hikohiko, me te miihini tika i te pae mō te āhua me te roa o ngā rauemi, kei te anga atu te Polybutylene Terephthalate (PBT)—he kirihou miihini e whakamahia whānuitia ana—ki te pēhanga kia puta ai he kounga mata tino pai.
Ahakoa tōna pakari ā-pūkaha me te ā-wera, ka ngāwari te PBT ki ngā hapa o te mata i te wā e tukatukahia ana—ina koa ka pāngia e te wera, te kutikuti, te makuku rānei. Ka pā tika ēnei hapa ki te āhua o te hua, tae atu ki te pono o te mahi.
E ai ki ngā raraunga ahumahi, ko ngā hapa mata tino kitea i roto i ngā hua PBT ko:
• Ngā Ārai Hiriwa/Ngā Tohu Wai: Ko ngā hapa e puta mai ana hei tauira porowhita i runga i te mata o te hua i puta mai i te makuku, te hau, te rauemi waro rānei e whai ana i te ahunga rere
• Ngā Tohu Hau: Ngā pokanga mata, ngā mirumiru rānei e puta ana ina kore e taea e ngā hau i roto i te rewa te puta katoa
• Ngā Tohu Rere: Ngā tauira mata e puta mai ana i te rere koretake o ngā rauemi
• Pānga Kiri Karaka: He rite te āhua o te mata ki te kiri karaka
• Ngā karawarawa o te mata: Ngā kino o te mata i puta mai i te waku i te wā e whakamahia ana
Ehara i te mea ko te āhua o te hua anake te pānga o ēnei hapa, engari ka arahi pea ki ngā raruraru mahi. He tino kitea ngā raruraru rakuraku o te mata i roto i ngā whare motuka papai me ngā hikohiko kaihoko, me ngā tatauranga e whakaatu ana neke atu i te 65% o ngā kaihoko e whakaaro ana he tohu nui te ātete ki te rakuraku i te aromatawai i te kounga o te hua.
Me pēhea e taea ai e ngā kaihanga PBT te wikitoria i ēnei wero o te koha mata?Auahatanga Hanga Rauemi!
Hangarau Whakarerekētanga Hiko:Ko ngā rauemi PBT raupapa Ultradur® Advanced hou a BASF e whakamahi ana i te hangarau whakarerekētanga hiato maha-wāhanga auaha, e whakarei ake ana i te pakeke o te mata me te ātete ki te rakuraku mā te whakauru i ngā ōwehenga motuhake o ngā wāhanga PMMA ki roto i te matihiko PBT. E whakaatu ana ngā raraunga whakamātautau ka taea e ēnei rauemi te whakatutuki i te pakeke o te pene ki te 1H-2H, neke atu i te 30% teitei ake i te PBT tuku iho.
Hangarau whakarei-nano:Kua whakawhanakehia e Covestro ngā whakatakotoranga PBT whakarei ake i te nano-silica e whakanui ana i te pakeke o te mata ki te taumata 1HB me te pupuri tonu i te mārama o ngā rauemi, e whakapai ake ana i te ātete ki te rakuraku mā te 40%. He tino pai tēnei hangarau mō ngā roto o ngā motuka me ngā whare hua hiko teitei me ngā whakaritenga āhua tino pakari.
Hangarau Tāpiri-hangai-Silicon:Hei whakatika i ēnei take tino nui mō te mahi, kua whakawhanakehia e SILIKE, he kaihanga auaha matua i roto i te hangarau tāpiri polymer, he kohinga o ngā otinga tāpiri e hangai ana ki te siloxane i hangaia mō te PBT me ētahi atu kirihou wera. Ka aro atu ēnei tāpiri whai hua ki ngā pūtake o ngā hapa o te mata, ā, ka whakapai ake i te mahi tukatuka me te roa o te hua.
Ngā Otinga Tāpiri-Hikorona a SILIKE mō te Whakapai Ake i te Kounga Mata PBT
Ko te Silicone Masterbatch LYSI-408 he whakatakotoranga i hangaia ki te pellets me te 30% te siloxane polymer taumaha-ira tino teitei kua whakamararatia ki roto i te polyester (PET). He whānuitia te whakamahinga hei tāpiringa whai hua mō te PET, PBT, me te pūnaha kapia hototahi hei whakapai ake i ngā āhuatanga tukatuka me te kounga o te mata.
Ngā painga matua o te tukatuka tāpiringa LYSI-408 mō te kirihou hangarau PBT:
