I-Propionic Acid National Standard (GB Specifications)
Izinga lezwe le-propionic acid lihlathulula ngokucacileko ukubukeka kwalo: kufanele libe yinto engenambala, ekhanyako enephunga elibukhali, begodu umbala wayo kufanele uhlangabezane namazinga athileko we-colorimetric (isib., inani le-APHA elingadluli umkhawulo obekiweko) ukuqinisekisa bona umkhiqizo uhlangabezana neemfuneko zekhwalithi yokubukeka.
Ngokuya ngobumsulwa, izinga lezwe ligunyaza ubuncani be-propionic acid obungu-99.0%. Isidingo sokuhlanzeka okuphezulu siqinisekisa bona i-propionic acid iletha ukusebenza okuzinzileko nokuthembekileko kizo zoke iindlela ezihlukahlukeneko zokukhiqiza nokusetjenziswa. Ukuqukethwe komswakama yinto eqakathekileko ethinta ikhwalithi yomkhiqizo; ngokwezinga, okuqukethwe kwamanzi kufanele kulawulwe ngaphasi kwe-0.5% ukukhandela umswakama omnengi bona ungaphazamisi izakhiwo zamakhemikhali nokusebenza kwawo. I-esidi, njengesibonisi esiqakathekileko, nayo icaciswe ngokucacileko: i-esidi (evezwe njengengcenye yesisindo, ebalwa njenge-propionic acid) kufanele iwe ngaphakathi kwebanga elichaziweko ukuqinisekisa ukuzinza kwamakhemikhali womkhiqizo nokusabela kuhlangabezana neemfuneko. Okuqukethwe yinsimbi ebudisi kukhawulelwe khulu emazingeni—umthofu, i-mercury, nezinye iinsimbi ezisindako kukhawulelwe emazingeni aphasi khulu, ngokuvamileko alinganiswa nge-ppm (amalunga ngesigidi), ukuqinisekisa ukuphepha kokusetjenziswa ekudleni, kwemithi, nezinye iimboni ezibucayi.
Izinga lezwe loke libuye libeke iimfuneko eziqondileko zokuminyana. Emazingeni womtjhiso atjhiwoko (isib., 20°C), ukuminyana kufanele kuwele ngaphakathi kwebanga elichaziweko, okutjengisa bona ubujamo bomkhiqizo buhambisana na namazinga. Ibanga lokubilisa ngenye into eqakathekileko: i-propionic acid kufanele ibe nebanga lokubila elivamise ukuba yi-140°C ukuya ku-142°C, ukuqinisekisa ukuzinza kwayo kokutjhisa nokutjhuguluka kwayo kuhlangabezana neemfuno ezihambisanako zebubulo. Ukuqukethwe kwe-chloride kulawulwa ngokuqinileko, ngezinga elifuna bona amazinga we-chloride abe ngaphasi komkhawulo othileko (isib., 0.001%) ukukhandela imithelela emimbi ekhwalithi yomkhiqizo nokusetjenziswa okulandelako. Okuqukethwe yinsimbi nakho kunemkhawulo ecacileko, ngokuvamileko engadluli i-0.0001%, ukubalekela izakhi zensimbi ezithinta umbala, ukuzinza, nokusebenza kwe-propionic acid eensetjenzisweni ezithileko ezikhethekileko.
Malungana nokuncibilika, izinga lezwe loke lifuna bona i-propionic acid itjengise ukuncibilika okuhle eentweni ezithileko (isib., i-ethanol, i-diethyl ether), ukuvumela ukuhlanganiswa okupheleleko emazingeni athileko ukuhlangabezana neemfuneko zokwakheka kizo zoke iinkhathi zokusebenzisa.

I-Shandong Pulisi Chemical Co., Ltd. ngumkhiqizi okhethekileko nomthengisi we-propionic acid yekhwalithi ephezulu ye-propionic acid e-China, ozinikele ekuletheni ukuhlanzeka okungaguqukiko, ukuphakelwa okuthembekileko, kanye nezisombululo ezilungiselelwe amakhasimende wamabubulo wephasi loke. I-propionic acid yethu ikhiqizwa ngaphasi kwamazinga aqinileko we-GB/T 10615, ngobumsulwa bezinga eliphezulu elifikelela ku-≥99.5% kanye nezinga lokuthoma elifinyelela ku-≥99.0%, elinomswakama omncani, okuqukethwe yinsimbi ephasi, kanye namazinga wensimbi ebudisi alawulwako ukuhlangabezana neemfuneko ezitlhogekako zokusetjenziswa okuhlukahlukeneko.
Yenziwe ngethekhnoloji ethuthukisiweko ye-propylene oxidation, i-propionic acid yethu iqinisekisa ubujamo bamakhemikhali obuzinzileko, ukuncibilika okuhle khulu, kanye nekhwalithi engaguqukiko iqoqo ngemva kweqoqo. Isebenza njengesisetjenziswa esiqakathekileko ekuhlanganisweni kwezinto eziphilako, ukwakhiwa kweplastiki, iinkambo zokufaka igezi, ukulondolozwa kokudla nokudla, kanye nokukhiqizwa kwemithi namakhemikhali wezokulima. Ngokusekelwa kwelabhorethri yethu yangaphakathi yokulawula ikhwalithi kanye namaphrothokholi wokuhlola apheleleko, woke umthwalo uhambisana ne-COA epheleleko, i-MSDS, neminye imitlolo yokuthobela ukwenza lula ukungeniswa nokusetjenziswa okulula ephasini loke.
Njengombana sineminyaka eminengi yokuthumela ngaphandle e-Asia, e-Europe, e-Middle East, nangaphezulu, sinikela ngeendlela zokupakisha eziguquguqukako, intengo ephalisanako, kanye namathemu wokulethwa athembekileko afakahlangana i-FOB, i-CIF, ne-DDP. Noma ngabe udinga ama-oda amancani wokulinga nofana izinto ezinengi, isiqhema sethu esizinikeleko sikulungele ukunikela ngesizo lobuthekhnikhi eliphendulako kanye nesevisi eyenziwe ngokwezifiso ukuhlangabezana neendingo zakho ezihlukileko zebhizinisi.
