Hydroxypyl methyplulose (HPMC) ƙari ne wanda aka ƙara yin amfani da shi sosai a cikin gini, abinci da sauran filayen. Yana da kyakkyawar thickening, fim-foring, samar da da emulsify. Hanyar hade ta dace tana da mahimmanci don tabbatar da aikinta da ingancin samfurin.
1. Shiri
Tsarin kayan aiki: Tabbatar amfani da foda mai inganci. Zaɓi dankan da ya dace da takamaiman kayan aikin.
Kayan aiki na kayan aiki: Haɗin-sama mai saurin sauri, yawanci ana amfani da shi ko na yau da kullun. Yakamata kayan ya zama mai tsabta da kuma gurbataccen gurbata.
Zaɓuɓɓukan Abinci: HPMC yawanci yana narkewa a cikin ruwan sanyi, amma ƙwayoyin cuta ko wasu masu jarida kuma ana iya amfani dasu a wasu lokuta. Zabi da damar da ya dace yana da mahimmanci don tasirin hadawa da kuma aikin samfurin ƙarshe.
2. Matakai masu hade
Protalfment: Ya kamata a preedder foda don cire lumps da impurities don tabbatar da rarrabuwar kawuna.
Bugu da kari:
Hanyar watsawa ta ruwan sanyi: zuba adadin ruwan sanyi a cikin mahautsini, fara motsawa, kuma a hankali ƙara HPMC foda. Guji ƙara da yawa a lokaci guda don hana agglomeration. Ci gaba da motsawa har sai foda ya lalace.
Hanyar watsawa mai zafi ta ruwa: Mix HPMC foda tare da wasu ruwan sanyi don samar da dakatar, sannan kuma a zuba shi cikin ruwan zafi mai tsanani ga 70-90 ° C. Dama a saurin saurin narke, sai a ƙara ruwan sanyi don sanyaya zuwa zazzabi a ɗakin don samun mafita ta ƙarshe.
Rikita da Thickening:
Lokacin da HPMC ya narke cikin ruwa, an dakatar da dakatarwa. Kamar yadda lokacin motsawa yana ƙaruwa kuma zazzabi ya ragu, visci sananne yana ƙaruwa har sai an narkar da shi gaba ɗaya. Lokacin rushewa yawanci yana ɗaukar minti 30 zuwa sa'o'i da yawa, gwargwadon danko da kuma gamu da HPMC.
Don tabbatar da cikakkiyar rushewa, ana iya samun mafita ya tsaya na tsawon lokaci (kamar na dare) don cimma ingantaccen danko.
Gyara da daidaitawa:
Idan ya cancanta, za a iya haɗa kaddarfin mafita ta hanyar ƙara wasu kayan abinci (kamar abubuwan adana, thickeners, da sauransu). Bugu da kari ya kamata a yi a hankali kuma tabbatar da rarraba kayan aiki.
Tigarwa da kuma defoaming:
Don cire rashin wadataccen barbashi da kumburin iska, ana iya amfani da tace ko degasser. Tigtration na iya cire immurities, yayin da degassing yana taimakawa don samun ƙarin bayani.
3. TAFIYA
Ingancin ruwa da zazzabi: ingancin ruwa yana da tasiri mai mahimmanci a kan rushewar HPMC. An ba da shawarar yin amfani da ruwa mai taushi ko ruwa mai narkewa don kauce wa geration wanda aka haifar da shi ta hanyar alli da ions a cikin ruwa mai wuya. Yawan zazzabi sosai ko kuma ƙarancin zafin jiki na HPMC kuma ya kamata a sarrafa shi cikin kewayon da ya dace.
Saurin motsa jiki da lokaci: maɗaurin sauri mai motsawa na iya gabatar da babban adadin iska da tsari na kumfa; Harlearancin saurin motsa jiki na iya haifar da haɗuwa mara daidaituwa. Ya kamata a daidaita sigar motsawa gwargwadon takamaiman kayan aiki da tsari.
Hana da agglomeration: Lokacin da ƙara HPMC foda, ya kamata a ƙara a hankali kuma a ko'ina, kuma a ko'ina, kuma a ci gaba da motsawa don hana samuwar agglomerates. Ana iya amfani da foda tare da wasu ruwan sanyi ko kuma ana iya amfani da wakilin anti-cakinda.
Storage and use: The prepared HPMC solution should be stored in a closed container to avoid light and high temperature. Lokacin da aka adana na dogon lokaci, ya kamata a bincika yanayin mafita a kai a kai don hana hazo ko lalacewa.
Hadawa Hydroxypropyl methylcellulose yana buƙatar ingantaccen tsari tsari da tsarin aiki don tabbatar da aikinta da sakamako a cikin samfurin ƙarshe. Ta hanyar zaɓin kayan aiki daidai, amfani da hanyar haɗi, hanyar haɗawa da takobi, mafi kyawun hanyoyin HPMC na iya kasancewa a shirye don biyan bukatun wuraren aikace-aikace daban-daban. A cikin ainihin aiki, gyare-gyare da abubuwan kirkirar ya kamata a yi bisa ga takamaiman yanayi don samun tasirin hadawa sosai.
