Propionic Acid National Standard (GB Specifications)
Say nasyonal ya estandarte parad propionic acid et malinew ya mangiiter na kabaliksan ed itsura to: nepeg ya andiay kolor, transparent ya likido ya walay angob to, tan say kolor to et nepeg ya makaabot ed espisipikon estandarte na visual colorimetric (alimbawa, say APHA value to et ag onlampas ed sakey ya limitasyon) pian naseguro ya say produkto et makaabot ed saray kakaukolanen ed kalidad na itsura.
No nipaakar ed kalinisan, say estandarte na bansa et mangigaganggan na minimum ya propionic acid content ya 99.0%. Sayan kakaukolanen ya atagey so inkapuro to et mamaseguro ya say propionic acid et mangiter na malet tan napanmatalkan ya performance ed nanduruman senaryo na produksyon tan aplikasyon ed industriya. Say danum et sakey a kritikal a sengegan ya mangaapekta ed kalidad na produkto; unong ed estandarte, say karga na danum et nepeg ya kontroladon abeba nen 0.5% pian ag makaamper so sobran danum ed saray kemikal tan performance to. Say acidity, bilang manunan indikasyon, et malinew met ya nibaga: say acidity (ya ibalikas bilang mass fraction, ya kinalkula bilang propionic acid) et nepeg ya onloob ed sakey a depinidon range pian naseguro ya say chemical stability tan reactivity na produkto et makasumpal ed saray kakaukolanen. Say karga na ambelat iran metal et limitado ed estandarte—say tingga, mercury, tan arum niran ambelat a metal et limitado ed abeban tuloy iran lebel, a kaslakan et nasukat ed ppm (parts per million), pian naseguro so kaligenan ya usaren ed tagano, tambal, tan arum niran sensitibon industriya.
Say estandarte na bansa et mangiiter met na eksakton kakaukolanen ed karakel na totoo. Diad sakey a nibaga ya temperatura (alimbawa, 20°C), say densidad et nepeg ya onloob ed sakey a nibaga ya range, ya mangipapatnag no kasin say pisikal iran kablian na produkto et mitunosan ed saray estandarte. Say boiling range et sananey nin manunan konsiderasyon: say propionic acid et nepeg ya walay boiling range to ya 140°C – 142°C, pian naseguro ya say thermal stability tan volatility to et makatunongan ed saray pankaukolan na industriya. Say karga na chloride et malet ya regulado, ya say estandarte et mankaukolan ya say lebel na chloride et walad leksab na sakey ya espisipikon threshold (alimbawa, 0.001%) pian naprebentaan so makapuy ya epekto ed kalidad na produkto tan say ontumbok ya proseso. Say karga na iron et walaan met na malinew iran limitasyon, ya ag onlampas ed 0.0001%, pian napaliisan so iron elements ya mangapekta ed kolor, inkapekder, tan performance na propionic acid ed pigaran espisyal ya aplikasyon.
Nipaakar ed inkatunaw, say estandarte na bansa et mankaukolan na propionic acid pian nawalaan na maong a inkatunaw ed espisipikon solvent (alimbawa, ethanol, diethyl ether), ya mangiter na sigpot a pakatunaw ed pigaran ratio pian nasumpal iray kakaukolanen ed panagporma ed nanduruman senaryo na aplikasyon.

Say Shandong Pulisi Chemical Co., Ltd. et sakey ya espisyal a manggagawa tan mansusuplay na de-kalidad ya industrial-grade propionic acid ed China, ya dedikado ed pangiter na pirmin kalinisan, napanmatalkan a suplay, tan saray solusyon ya parad saray kliyente na industriya ed interon mundo. Say propionic acid mi et ginawa unong ed istrikton estandarte na GB/T 10615, ya say premium grade purity et onabot ed ≥99.5% tan say first grade et ≥99.0%, ya walaan na abeban danum, abeban iron content, tan kontroladon heavy metal levels pian nasumpal iray mankaukolan na nanduruman end-use applications.
Ginawa panamegley na advanced propylene oxidation technology, say propionic acid mi et mangiseguro na malet iran kemikal, ekselentin solubility, tan tuloytuloy ya kalidad na kada batch. Saya so manserbin manunan intermediate ed organic synthesis, panaggawa na plastik, proseso na electroplating, panagpreserba na pakanen tan naakan, tan panaggawa na tambal tan agrochemical. Susuportaan na in-house quality control laboratory mi tan saray komprehensibon testing protocols, kada kargamento et walay kaiba ton kompleton COA, MSDS, tan arum niran dokumento na compliance pian napagaan so maabig ya import tan pangusar ed interon mundo.
Lapud dakel lan taon ya eksperiensya mi ed panag-export ed Asia, Europe, Middle East, tan arum ni, mangiyoopresi kami na nababalang iran opsyon ed panagbalot, kompetitibon presyo, tan napanmatalkan iran termino ed pangiter kaiba lay FOB, CIF, tan DDP. Balanglan mankaukolan kayo na melag iran trial order odino angkakabaleg iran bulk supplies, say dedikadon grupo mi et akaparaan ya mangiter na responsive technical support tan customized service pian nasumpal iray nikadkaduman pankaukolan yo ed negosyo.
