Asidi ya Propionike Itegeko ry'Igihugu (Ibisobanuro vya GB)
Itegeko ry’igihugu ry’aside ya propionic risobanura neza ukuntu isa: itegerezwa kuba amazi atagira ibara, abonekerana afise akamoto gakomeye, kandi ibara ryayo ritegerezwa guhura n’ingingo ngenderwako zihariye z’amabara y’amaso (nk’akarorero, n’agaciro ka APHA katarenze urugero rutomoye) kugira ngo igicuruzwa kibe gihuye n’ibisabwa vy’uburyo bwo kugaragara.
Ku bijanye n’ubusuku, itegeko ry’igihugu risaba ko aside propionique igira 99,0%. Ivyo bisabwa vy’ubusuku bwinshi bituma aside ya propionic itanga ibikorwa bihamye kandi vyizewe mu bikorwa bitandukanye vy’inganda n’ugukoresha. Ubukonje burimwo ni ikintu gihambaye cane gigira ico gikoze ku buzima bw’igicuruzwa; ku rugero, amazi ategerezwa kugenzurwa munsi ya 0,5% kugira ngo ubukonje burenze urugero ntibubangamire imiterere yayo y’imiti n’imikorere yayo. Asidi, nk’ikimenyetso nyamukuru, na yo nyene iratomorwa neza: asidi (igaragazwa nk’igice c’uburemere, iharurwa nk’aside ya propionic) itegerezwa kugwa mu rugero rwategekanijwe kugira ngo igikoresho gishobore gukomera mu buryo bw’imiti n’ubushobozi bwo gusubiramwo ibintu bihuye n’ibisabwa. Ivyuma biremerera biri muri vyo birafise aho bigarukira cane mu rugero—ivyuma vy’amabuye y’agaciro bita lead, mercury be n’ibindi vyuma biremerera bifise aho bigarukira ku rugero ruto cane, mu bisanzwe bipimwa mu ppm (ibice ku miliyoni), kugira ngo bibe vyiza bikoreshejwe mu vyo kurya, mu vy’imiti no mu zindi nganda zikomeye.
Itegeko ry’igihugu na ryo nyene rishiraho ibisabwa vy’ukuri ku bijanye n’uburemere bw’ibintu. Ku bushuhe butegekanijwe (nk’akarorero, 20°C), uburemere butegerezwa kugwa mu rugero rwategekanijwe, bikaba vyerekana nimba imiterere y’umubiri y’ico kintu ihuye n’ingingo mfatirwako. Igitigiri c’uguteka ni ikindi kintu nyamukuru co kwitwararika: aside ya propionic itegerezwa kuba ifise igitigiri c’uguteka muri rusangi 140°C – 142°C, kugira ngo ubushuhe bwayo n’uguhinduka kwayo bihure n’ivyo inganda zisaba. Ivyo birimwo kloride birategekanijwe cane, aho urugero rusaba ko urugero rwa kloride ruba munsi y’urugero runaka (nk’akarorero, 0,001%) kugira ngo hatagira ingaruka mbi ku buzima bw’ibicuruzwa no ku gutunganya ibintu bikurikira. Ivyuma birimwo na vyo nyene birafise imipaka igaragara, mu bisanzwe ntibirenze 0,0001%, kugira ngo ntihagire ibintu vy’icuma bigira ico bikoze ku rangi, ku gushikama, no ku bushobozi bwa aside ya propionic mu bikorwa bimwebimwe vy’umwihariko.
Ku bijanye n’ugusenyuka, ingingo ngenderwako y’igihugu isaba ko aside ya propionic yerekana ubushobozi bwiza bwo gusenyuka mu binyobwa vyihariye (nk’akarorero, ethanol, diethyl ether), bikaba vyemerera gusenyuka gushitse ku bipimo bimwebimwe kugira ngo ishobore gushitsa ibisabwa mu guhingura mu bihe bitandukanye vyo gukoresha.

Shandong Pulisi Chemical Co., Ltd. ni uruganda rwihariye rukora kandi rutanga aside ya propionic y’agaciro kanini mu Bushinwa, yiyemeje gutanga ubusuku budahinduka, ukwizigirwa, n’imiti ibereye abaguzi b’inganda bo kw’isi yose. Asidi yacu ya propionic ikoreshwa hakurikijwe ingingo ngenderwako zikomeye za GB/T 10615, n’ubusuku bw’urugero rwo hejuru bushika ku ≥99.5% n’urugero rwa mbere ku ≥99.0%, ifise ubukonje buke, ivyuma bike, n’ivyuma bikomeye bigenzurwa kugira ngo bishobore gushitsa ibisabwa vy’ikoreshwa ritandukanye.
Ikoreshwa biciye ku buhinga buteye imbere bwo guhindura ivyuma bita propylene oxidation, aside yacu ya propionic iratuma habaho imiterere y’imiti ihamye, igashobora gusenyuka neza cane, kandi igatuma habaho uburyo bumwe bumwe. Ikora nk’igikoresho nyamukuru co hagati mu guhingura ibintu bifise ubuzima, mu guhingura amapulasitike, mu guhingura ibintu bikoresheje umuyagankuba, mu kuzigama ibifungurwa n’ibifungurwa, no mu guhingura imiti n’ivy’uburimyi. Ishigikiwe na laboratwari yacu yo mu nzu yo kugenzura uburyo n’amategeko yose yo gupima, ikintu cose coherezwa kijana n’ivya COA vyuzuye, MSDS, n’izindi nyandiko z’ukubahiriza amategeko kugira ngo bishobore gutuma ibintu biva hanze bigenda neza no kubikoresha kw’isi yose.
Kubera ko dufise imyaka myinshi y’ubumenyi bwo kwohereza ibintu hanze muri Aziya, Uburayi, Uburasirazuba bwo Hagati, n’ahandi, turatanga uburyo bwo gupfunyika bushobora guhinduka, ibiciro bihuye, n’amasezerano yo kubishikana yizigirwa harimwo FOB, CIF, na DDP. Waba ukeneye amategeko mato mato y’igerageza canke ibikoresho vyinshi, ikipe yacu yiyemeje kwitegurira gutanga ubufasha bw’ubuhinga n’ibikorwa bihuye n’ivyo ukeneye mu bucuruzi bwawe.
