He aha tonu te Titanium Dioxide?
Te hauhāotaitaniuma (TiO2)He matū kore-waro te mea he mea hanga mai i te titanium me te hāora, ā, koia te tae ma tino whai hua e wātea ana ki ngā umanga o ēnei rā. He kupu ngāwari noa iho, he paura ma pai, ina whakauruhia ki roto i ngā peita, kirihou, pepa, i tētahi atu rauemi rānei, ka puta he mā, he kanapa, he mārama hoki.
Ka tutuki i a TiO2 tēnei nā te mea he teitei rawa te taupū whakaata -- mai i te 2.55 ki te 2.76 i runga i te āhua o te tioata -- he teitei ake tēnei i tētahi atu tae mā. Hei whakataurite, ko te taupū whakaata o te konutea waikura he 2.0, ko te konupūmā kāponāte he 1.6, me te talc he 1.57. Ko te tikanga he nui ake te whai hua o te TiO2 ki te whakamarara i te mārama e kitea ana, koia te take ahakoa he iti noa te nui ka whakapai ake i te kaha me te kanapa o te uhi.
>> Whakautu Nugget: Ko te titanium dioxide (TiO2) he tae ma kore-ora me te taupū whakaata teitei rawa (2.55-2.76) i roto i ngā tae ma katoa, e kore e taea te whakakapi mō te whakarato i te mā, te kanapa, me te mārama puta noa i ngā paninga, kirihou, pepa, me ētahi atu rauemi.
Mai i te tirohanga matū, he tino pumau te TiO2. Kāore e tauhohe ki te nuinga o ngā waikawa, ngā kawakore, ngā whakarewa rauropi rānei i raro i ngā āhuatanga noa. Kāore e paitini, kāore e mura, ā, he ātete ki te pirau UV -- ngā āhuatanga e pai ai te whakamahi i roto i ngā takai kai, ngā mea whakapaipai, tae noa ki ngā papa rongoā, hei tāpiri atu ki ōna tono ahumahi matua.
Ngā Āhua Tioata e Rua: Rutile vs. Anatase
E toru ngā hanganga tioata o te TiO2, engari e rua anake ngā mea nui ki te hokohoko: ko te rutile me te anatase. Ehara i te mea he mea mātauranga noa iho te rerekētanga i waenganui i a rāua - engari ka whakatau tika ko tēhea momo me tono e tō wheketere.
>> Whakautu Nugget: He nui ake te taupū whakaata o te Rutile TiO2 (2.76), he pai ake te ātete ki te huarere, ā, koinei te whiringa pai mō ngā paninga o waho, ngā kirihou, me ngā tono pakari. He iti ake te taupū whakaata o te Anatase TiO2 (2.55) engari he mā ake te tae, ā, he iti ake te utu mō ngā tono o roto pērā i te pepa me ngā peita o roto.
E 85-90% pea o te nui o te TiO2 o te ao e whakaputaina ana e te Rutile TiO2, nā te mea he pai mō ngā mahi o waho nā te mea he pumau te āhua o te whakaahua. I roto i aku tau 10 e mahi tahi ana me ngā kaihanga paninga, kua kite tonu ahau he iti ake ngā amuamu mō te memeha o te tae o ngā kaupapa e tohu ana i ngā taumata rutile mō ngā paninga hoahoanga o waho, ki te whakaritea ki ngā kaupapa i ngana ki te whakamahi i ngā taumata anatase o waho.
Ko te rerekētanga hangarau matua kei roto i te mahi photocatalytic: tata ki te 10 ngā wā ka nui ake te photoactive o te anatase TiO2 i te rutile, ko te tikanga ka nui ake ngā rauropi kore utu ka puta ina pāngia e te mārama UV -- ka whakaekea e ēnei rauropi te hononga rauropi i roto i ngā peita me ngā kirihou, ka puta te kirikiri, te ngaronga o te kanapa, me te memeha o te tae. Koinei tonu te take i hangaia ai ngā karaehe anatase me ngā maimoatanga mata tāpiri ina whakamahia i roto i tētahi tono me te pānga UV tūpono.
Kei hea te whakamahinga o te hauhāotaita? E ono ngā umanga matua
>> Whakautu Nugget: E whakamahia ana te hauhā titanium i roto i ngā ahumahi matua e ono -- ngā paninga (35% o te tono o te ao), ngā kirihou (25%), te pepa (12%), ngā waituhi (5%), te rapa, me te masterbatch -- ko te toenga o te rahinga ka whakamahia ki ngā tono motuhake pēnei i te whakapaipai, te kai, me ngā rongoā.
1. Ngā Paninga me ngā Peita (35% o te Hiahia TiO2 o te Ao)
Ko te umanga paninga te kaihoko nui rawa atu o te TiO2. I roto i te hanganga peita hoahoanga noa, ko te TiO2 he 15-25% o te taumaha katoa o te hanganga, ā, tata ki te 40-50% o te utu o ngā rauemi mata. Nā te mea ka tukuna e te TiO2 te kaha huna me te mā e aromatawaihia ana e ngā kaihoko peita ki ō rātou kanohi.
E ai ki ngā raraunga mai i te American Coatings Association, tata ki te 2.6 miriona tāne metrika o te TiO2 i pau i te mākete peita me ngā paninga o te ao i te tau 2025. I roto i aku haerenga wheketere ki ngā kaihanga paninga i Inia me Turkey, kua kite ahau ahakoa ngā kaihanga peita e whakamahi ana i ngā hanganga taumata-whakaurunga e kore e whakaiti i te kounga TiO2 -- nā te mea ko te tikanga o te TiO2 ngoikore he toru ngā paninga hei utu mō te rua, ka piki ake te utu mahi me te wā mō ā rātou kiritaki.
2. Kirihou me te Masterbatch (25% o te Hiahia TiO2 o te Ao)
I roto i te umanga kirihou, e rua ngā mahi a te TiO2: ka puta te tae mā kanapa e tumanakohia ana e ngā kaihoko mai i ngā hua pēnei i ngā paipa PVC, ngā kōtaha matapihi, me ngā kiriata takai, ā, ka tiaki hoki i te hanganga polymer mai i te pirau UV. Ka mimiti te TiO2 i te hihi UV ka tukuna hei wera kore kino, ka roa ake te ora o ngā hua kirihou o waho.
Mō ngā kaihanga matua-patunga, ko ngā taumata uta TiO2 kei waenganui i te 50-70% te taumaha, ko te tikanga ko te marara, te rere, me te pumau wera o te karaehe TiO2 te mea e whakatau tika ana i te whai huatanga o te whakaputanga. Ka taea e te karaehe TiO2 he ngoikore te marara te aukati i te kete mata, ngā hapa mata, me te tae koretake - he raruraru ka taea te utu i te kaihanga matua-patunga mano tāra ia rā i te wā kore mahi.
3. Te Hanga Pepa (12% o te Hiahia TiO2 o te Ao)
I roto i te umanga pepa, ka whakamahia te TiO2 i roto i ngā pepa whakapaipai kounga teitei, pepa ranumī, me te pepa paipera, ina hiahiatia te matotoru mōrahi. E 10 ngā wā o te matotoru o te TiO2 i te konupūmā kāponāte i te taumata uta kotahi, e āhei ai ngā kaihanga pepa ki te whakaputa pepa angiangi, māmā ake, me te kore e whakaiti i te ātete tā.
4. Ngā Waituhi Tā, te Rapa, me ngā Whakamahinga Motuhake
I roto i te umanga waituhi tā, ko te TiO2 te tae mā i roto i ngā waituhi flexographic me te gravure mō ngā takai ngāwari. Nā te mea he angiangi rawa te matotoru o te kiriata waituhi i te kiriata peita -- ko te tikanga he 1-5 microns te matotoru, he 50-100 microns te matotoru -- me tino pai, me ōrite hoki te tohatoha rahi matūriki o te TiO2 e whakamahia ana i roto i ngā waituhi kia pai ai te mārama i ngā taumaha kiriata iti.
I roto i te umanga rapa, ka whakamahia te TiO2 hei tae mā, hei whakakī whakakaha hoki i roto i ngā hua pēnei i ngā potae pakitara mā, ngā kapu hū, me ngā papa rapa. He maha ngā wā ka pai ake ngā momo Anatase i roto i ngā tono rapa ina he pai te āhua o te tae mā ngawari ake, ā, ehara i te ātete ki te huarere kino te mea matua e hiahiatia ana.
He pēhea teTaihauāwhioI hangaia?
>> Whakautu Nugget: E rua ngā tukanga ahumahi e hangaia ai te TiO2 -- te tukanga whanariki (mā te whakamahi i te konganuku ilmenite me te waikawa whanariki, e whakaputa ana i ngā taumata rutile me te anatase) me te tukanga chloride (mā te whakamahi i te rutile kounga teitei, te rutile hangai rānei me te hau chlorine, e whakaputa ana i ngā taumata rutile anake me te parakore teitei ake me te whakahaere rahi matūriki kia kaha ake).
Ko te tukanga whanariki, e tata ana ki te 40% o te hanga o te ao, ka tīmata ki te ilmenite (FeTiO3) i keria ki roto i te waikawa whanariki kukū. He ngāwari ake tēnei tukanga -- ka taea te whakamahi i ngā konganuku iti te kounga me te whakaputa i ngā hua rutile, anatase rānei i runga i ngā āhuatanga o te whakapūkara. Heoi, ka puta ake he nui ake ngā hua para, inā koa ko te whanariki rino, me whakahaere mā te hangarua, mā te whakakorenga rānei.
Ko te tukanga konukōre, e 60% pea o te putanga TiO2 o te ao, ka tīmata me te rutile kounga teitei, te ilmenite whakapai ake rānei, i tauhohehia ki te hau konukōre i te pāmahana teitei (900-1,000 C) hei whakaputa TiCl4, kātahi ka waikurahia hei whakaputa TiO2 tino parakore. Ka puta he hua mai i te tukanga konukōre he tohatoha rahi matūriki piri ake, ā, he kanapa ake te nuinga, engari me nui ake te utu o ngā rauemi whāngai me te whakahaere tukanga matatau.
I SUN BANG, ka mau tonu ā mātou hononga ki ngā kaihanga mā te whakamahi i ngā hangarau e rua, e āhei ai mātou ki te taunaki i te hua tino iti te utu, tino tika hoki mō ia tono a ia kiritaki, kaua e noho tahi ki te tukanga kotahi.
Te Mākete TiO2 o te Ao: He aha te Hiranga o tēnei mō tō Pakihi
>> Answer Nugget: Neke atu i te 7.3 miriona tāne mita te hanga TiO2 o te ao i te tau 2025, ā, tata ki te 45% o te katoa o Haina e whakaputa ana. E kiia ana ko te TiO2 he paearu mō ngā mahi ahumahi nā te mea e pā tika ana tōna whakamahinga ki ngā paninga, te hanga, me te putanga hanga.
E ai ki te Titanium Dioxide Manufacturers Association (TDMA), kua piki ake te tono TiO2 o te ao i te tere tipu ā-tau (CAGR) tata ki te 3.5-4.0% i roto i te tekau tau kua hipa, nā te noho tāone nui i roto i ngā ōhanga whakawhanake. Me whai TiO2 i roto i tana mekameka tuku ia whare noho hou, ia motuka hou, me ia taputapu hou.
Mō ngā kaihoko B2B, he mea nui te mārama ki ngā whanaketanga o te mākete TiO2 mō te whakamahere hoko. E toru ngā āhuatanga matua e pāngia ana ngā utu: te wātea o ngā rauemi whāngai (te putanga keri ilmenite me te rutile), ngā utu pūngao (he nui te kaha o ngā tukanga whanariki me te hauhāora), me ngā tauira tono ā-wā (ngā tihi o te hauwhā tuatahi ki te hauwhā tuarua mō ngā paninga, te kaha o te hauwhā tuatoru ki te hauwhā whā tekau i roto i ngā kirihou me te masterbatch).
He aha ngā Whakatakotoranga me Tirohia e ngā Kaihoko?
>> Answer Nugget: Ko ngā tawhā matua e rima me manatoko e ia kaihoko TiO2 ko: te ihirangi TiO2 (te nuinga >=92% mō te rutile), te kanapa (te uara Hunter L >=94), te kaha o te tae, te kaha whakaiti rānei (e pā ana ki te paerewa), te mimiti hinu (e tohu ana i te mararatanga, te nuinga 15-25 g/100g), me te tohatoha rahi matūriki (te rahi matūriki toharite ~0.25-0.30 um mō te marara mārama pai rawa atu).
I roto i aku wheako mahi tahi me ngā tīma hokohoko, ko te hapa tino noa e mahia ana e ngā kaihoko TiO2 tuatahi ko te whakatairite i te utu waeine mō ia tana me te kore e mārama ki ēnei rerekētanga whakatakotoranga. Ko te utu o tētahi hua TiO2 he $200/T iti iho, me nui ake pea ngā taumata uta 15-20% kia eke ki te kaha huna ōrite, ko te tikanga ka nui ake te utu whai hua mō ia mita tapawha o te hua kua oti me te iti ake o te rauemi mata.
Ngā Pātai Auau mō te Taitāniuma Hauhā
P: He haumaru te whakamahi i te hauhā titanium i roto i ngā hua kaihoko?
A: Kua whakarōpūtia te hauhā titanium hei mea e mōhiotia whānuitia ana he haumaru (GRAS) e te US FDA mō te whakamahinga i roto i te kai, te whakapaipai, me ngā rongoā. I te tau 2022, i whakaarohia e te Komihana Pākehā he aukati i te TiO2 hei tāpiringa kai (E171), i tīmata i te marama o Ākuhata 2022, engari e pā ana tēnei ki te TiO2 kai-kai e whakamahia ana hei tae -- kaua ki te TiO2 ahumahi e whakamahia ana i roto i ngā peita, kirihou, pepa rānei. Ko ngā taumata TiO2 ahumahi kei raro i te REACH (EC 1907/2006) ā, kei te tutuki tonu i ngā whakaritenga mō ā rātou whakamahinga. Ka whakaratohia e SUN BANG ngā hua katoa me ngā tuhinga REACH, RoHS, me te SGS katoa.
P: He aha te rahinga ota iti rawa (MOQ) mō TiO2?
A: I SUN BANG, ka tīmata te MOQ paerewa i te 1 tana mita, me te utu whakataetae e wātea ana mō ngā ota ipu-uta (20-28 MT) me ngā ota papatipu. Ka tukuna hoki e mātou he rahinga tauira (1-5 kg) kore utu mō te aromatawai hangarau tuatahi i mua i te tuku ki ngā ota arumoni.
P: Me pēhea te penapena i te TiO2 kia mau tonu ai te kounga?
A: Me rongoa te TiO2 ki roto i te taiao matao, maroke i roto i tōna takai hiri taketake. Ka taea e te makuku te whakaemi, ka pā kino ki te horapa. I raro i ngā tikanga rokiroki tika (te pāmahana i raro i te 40 C, te haumākū whanaunga i raro i te 60%), ka roa te ora o te TiO2 kāore anō kia whakatuwheratia mō te 24 marama neke atu rānei, kāore he hekenga kounga e taea te ine.
P: He aha te wā tuku noa mō te TiO2 mai i Haina?
A: Mō ngā momo rutile me anatase paerewa, kei te pupuri a SUN BANG i ngā taonga i roto i ā mātou pokapū putunga e 7 puta noa i Haina, e āhei ai te tuku i roto i ngā rā 7-15 o te whakaū ota. Ka rerekē ngā wā whakawhiti utanga moana i runga i te ūnga: 15-20 rā ki Āhia ki te Tonga-mā-rāwhiti, 25-30 rā ki te Middle East me Īnia, 30-35 rā ki Ūropi mā te Awa o Suez, me te 40-45 rā ki Brazil.
