Izinga Likazwelonke le-Propionic Acid (Imininingwane ye-GB)
Indinganiso kazwelonke ye-propionic acid ichaza ngokucacile ukubukeka kwayo: kufanele ibe uketshezi olungenambala, olusobala olunephunga elimnandi, futhi umbala wayo kumele uhlangabezane nezindinganiso ezithile zombala ezibonakalayo (isb., ngenani le-APHA elingadluli umkhawulo ocacisiwe) ukuqinisekisa ukuthi umkhiqizo uhlangabezana nezidingo zekhwalithi yokubukeka.
Ngokuphathelene nobumsulwa, indinganiso kazwelonke ifuna okuqukethwe okungenani kwe-propionic acid okungu-99.0%. Le mfuneko yobumsulwa obuphezulu iqinisekisa ukuthi i-propionic acid iletha ukusebenza okuzinzile nokuthembekile kuzo zonke izimo zokukhiqiza zezimboni kanye nokusetshenziswa. Okuqukethwe komswakama kuyisici esibalulekile esithinta ikhwalithi yomkhiqizo; ngokwendinganiso, okuqukethwe kwamanzi kumele kulawulwe ngaphansi kuka-0.5% ukuvimbela umswakama owedlulele ukuthi ungaphazamisi izakhiwo zawo zamakhemikhali kanye nokusebenza kwawo. Ubu-asidi, njengesibonakaliso esiyinhloko, buchazwe ngokucacile: ubu-asidi (obuvezwa njengengxenye yesisindo, obubalwa njenge-propionic acid) kumele bube ngaphakathi kobubanzi obuchaziwe ukuqinisekisa ukuzinza kwamakhemikhali omkhiqizo kanye nokusabela kwawo kuhlangabezana nezidingo. Okuqukethwe kwensimbi esindayo kunqunyelwe ngokuqinile endinganisweni—i-lead, i-mercury, nezinye izinsimbi ezisindayo kukhawulelwe emazingeni aphansi kakhulu, ngokuvamile kulinganiswa ku-ppm (izingxenye ngesigidi), ukuqinisekisa ukuphepha kokusetshenziswa ekudleni, kwezemithi, nakwezinye izimboni ezibucayi.
Izinga likazwelonke liphinde libeke izidingo eziqondile ekubunjweni. Ezingeni lokushisa elithile (isb., 20°C), ukubunjwa kumele kungene ngaphakathi kobubanzi obuchaziwe, okubonisa ukuthi izakhiwo zomzimba zomkhiqizo ziyahambisana yini nezindinganiso. Ububanzi bokubilisa bungenye into ebalulekile okufanele icatshangelwe: i-propionic acid kumele ibe nobubanzi bokubilisa obujwayelekile obungu-140°C – 142°C, ukuqinisekisa ukuthi ukuqina kwayo kokushisa kanye nokuguquguquka kwayo kuhlangabezana nezidingo zezimboni ezihambisanayo. Okuqukethwe kwe-chloride kulawulwa ngokuqinile, kanti izinga lidinga amazinga e-chloride abe ngaphansi komkhawulo othize (isb., 0.001%) ukuvimbela imiphumela emibi ekhwalithini yomkhiqizo kanye nokucutshungulwa okulandelayo. Okuqukethwe kwensimbi nakho kuncike emikhawulweni ecacile, ngokuvamile engadluli ku-0.0001%, ukugwema izakhi zensimbi ezithinta umbala, ukuzinza, kanye nokusebenza kwe-propionic acid kwezinye izinhlelo zokusebenza ezikhethekile.
Ngokuphathelene nokuncibilika, indinganiso kazwelonke idinga i-propionic acid ukuze ibonise ukuncibilika okuhle ezincibilikisini ezithile (isb., i-ethanol, i-diethyl ether), okuvumela ukuncibilika okuphelele ezilinganisweni ezithile ukuze kuhlangatshezwane nezidingo zokwakheka kuzo zonke izimo zokusetshenziswa ezahlukene.

I-Shandong Pulisi Chemical Co., Ltd. ingumkhiqizi okhethekile kanye nomhlinzeki we-propionic acid esezingeni eliphezulu yezimboni eShayina, ezinikele ekuletheni ubumsulwa obuqhubekayo, ukuphakelwa okuthembekile, kanye nezixazululo ezenzelwe amakhasimende ezimboni zomhlaba wonke. I-propionic acid yethu ikhiqizwa ngaphansi kwezindinganiso eziqinile ze-GB/T 10615, kanti ubumsulwa bezinga eliphezulu bufinyelela ku-≥99.5% kanye nebanga lokuqala ku-≥99.0%, enomswakama ophansi, okuqukethwe kwensimbi okuphansi, kanye namazinga ensimbi esindayo alawulwayo ukuze kuhlangatshezwane nezidingo ezidingekayo zezinhlelo zokusebenza ezahlukahlukene zokusetshenziswa.
Ikhiqizwa ngobuchwepheshe obuthuthukisiwe be-propylene oxidation, i-propionic acid yethu iqinisekisa izakhiwo zamakhemikhali ezizinzile, ukuncibilika okuhle kakhulu, kanye neqoqo lekhwalithi elihambisanayo. Isebenza njengesihluthulelo esibalulekile ekuhlanganisweni kwezinto eziphilayo, ukukhiqizwa kwepulasitiki, izinqubo zokufaka i-electroplating, ukugcinwa kokudla nokudla, kanye nokukhiqizwa kwemithi kanye namakhemikhali ezolimo. Isekelwa ilebhu yethu yokulawula ikhwalithi yangaphakathi kanye nezinqubo zokuhlola eziphelele, konke ukuthunyelwa kuhambisana ne-COA ephelele, i-MSDS, kanye neminye imibhalo yokuthobela imithetho ukuze kube lula ukungenisa nokusetshenziswa okubushelelezi emhlabeni jikelele.
Njengoba sineminyaka eminingi yokuhlangenwe nakho kokuthumela kwamanye amazwe e-Asia, eYurophu, eMpumalanga Ephakathi, nangale kwalokho, sinikeza izinketho zokupakisha eziguquguqukayo, amanani okuncintisana, kanye nemibandela yokulethwa ethembekile kufaka phakathi i-FOB, i-CIF, kanye ne-DDP. Kungakhathaliseki ukuthi udinga ama-oda amancane okuhlola noma izimpahla ezinkulu, ithimba lethu elizinikele likulungele ukunikeza ukwesekwa kobuchwepheshe okuphendulayo kanye nensizakalo eyenziwe ngokwezifiso ukuze kuhlangatshezwane nezidingo zakho zebhizinisi ezihlukile.
