Paerewa ā-Motu o te Waikawa Propionic (Ngā Whakatakotoranga GB)
E whakamārama mārama ana te paerewa ā-motu mō te waikawa propionic i tōna āhua: me waiho hei wai mārama, kore tae, he kakara kaha, ā, me tutuki i tōna tae ngā paerewa tae tirohanga motuhake (hei tauira, me te uara APHA kāore e neke ake i tētahi rohe kua tohua) kia tutuki ai i te hua ngā whakaritenga kounga āhua.
Mō te parakore, e whakahau ana te paerewa ā-motu kia 99.0% te iti rawa o te waikawa propionic. Mā tēnei whakaritenga parakore teitei ka taea e te waikawa propionic te whakaputa i te mahi pumau me te pono puta noa i ngā momo ahumahi whakaputa me ngā whakamahinga. He mea nui te nui o te makuku e pā ana ki te kounga o te hua; e ai ki te paerewa, me whakahaere te nui o te wai i raro i te 0.5% kia kore ai e pāngia e te makuku nui ōna āhuatanga matū me te mahi. Ko te waikawa, hei tohu matua, kua tohua hoki: me taka te waikawa (e whakaatuhia ana hei wāhanga papatipu, e tatauhia ana hei waikawa propionic) ki roto i tētahi awhe kua tautuhia kia tutuki ai ngā whakaritenga o te pumau matū me te tauhohenga o te hua. He tino herea te nui o te konganuku taumaha i roto i te paerewa—ko te mata, te mercury, me ētahi atu konganuku taumaha ka herea ki ngā taumata tino iti, e inehia ana i roto i te ppm (ngā wāhanga ia miriona), kia pai ai te whakamahi i roto i te kai, te rongoā, me ētahi atu ahumahi tairongo.
E whakatakoto ana hoki te paerewa ā-motu i ngā whakaritenga tika mō te mātotoru. I te pāmahana kua tohua (hei tauira, 20°C), me taka te mātotoru ki roto i tētahi awhe kua tautuhia, e whakaata ana mēnā e tutuki ana ngā āhuatanga ā-tinana o te hua ki ngā paerewa. Ko te awhe kohua tētahi atu whakaaro nui: me whai awhe kohua te waikawa propionic i te 140°C – 142°C, kia tutuki ai ngā hiahia ahumahi e rite ana ki tōna pumau wera me tōna āhuarangi. He tino ture te ihirangi hauota, me te paerewa e kī ana kia noho ngā taumata hauota i raro i tētahi paepae motuhake (hei tauira, 0.001%) hei ārai i ngā pānga kino ki te kounga o te hua me te tukatuka i muri mai. Kei raro hoki i ngā rohe mārama te ihirangi rino, kāore e neke ake i te 0.0001%, hei karo i ngā huānga rino e pā ki te tae, te pumau, me te mahi a te waikawa propionic i roto i ētahi tono motuhake.
Mō te wairewatanga, e hiahiatia ana e te paerewa ā-motu kia whakaatu te waikawa propionic i te wairewatanga pai i roto i ngā whakarewa motuhake (hei tauira, te etanoru, te diethyl ether), kia taea ai te whakaranu katoa i ētahi ōwehenga kia tutuki ai ngā whakaritenga whakatakotoranga puta noa i ngā horopaki tono rerekē.

He kaihanga me te kaiwhakarato motuhake a Shandong Pulisi Chemical Co., Ltd. o te waikawa propionic kounga teitei i Haina, e whakapau kaha ana ki te whakarato i te parakore pumau, te tuku pono, me ngā otinga kua whakaritea mō ngā kiritaki ahumahi o te ao. Ka hangaia tā mātou waikawa propionic i raro i ngā paerewa GB/T 10615 tino pakari, me te parakore kounga teitei e eke ana ki te ≥99.5% me te taumata tuatahi i te ≥99.0%, he iti te makuku, he iti te ihirangi rino, me ngā taumata konganuku taumaha kua whakahaeretia hei whakatutuki i ngā whakaritenga uaua o ngā tono whakamahinga mutunga kanorau.
I hangaia mā te hangarau whakakōkī propylene matatau, ka whakarite tā mātou waikawa propionic i ngā āhuatanga matū pumau, te wairewatanga pai, me te kounga ōrite i roto i ngā puranga i muri i ngā puranga. He takawaenga matua tēnei i roto i te hanga rauropi, te hanga kirihou, ngā tukanga whakakikorua hiko, te tiaki kai me te kai, me te hanga rongoā me te ahuwhenua. Mā te tautoko a tā mātou taiwhanga whakahaere kounga ā-whare me ngā kawa whakamātautau whānui, ka haere tahi ia uta me te COA katoa, MSDS, me ētahi atu tuhinga ture hei whakahaere i te kawemai me te whakamahi maeneene puta noa i te ao.
Neke atu i te tau o te wheako kaweake ki Āhia, ki Ūropi, ki te Waenganui Rawhiti, me tua atu, kei a mātou ngā kōwhiringa takai ngāwari, utu whakataetae, me ngā tikanga tuku pono tae atu ki te FOB, CIF, me te DDP. Ahakoa he iti ngā ota whakamātautau e hiahiatia ana e koe, he nui rānei ngā taonga, kua rite tā mātou tīma ki te whakarato tautoko hangarau arotau me te ratonga ritenga kia tutuki ai ō hiahia pakihi ahurei.
