Nigute ushobora gupima ubwiza bwa HPMC?

Ni ubuhe buryo bwo kwirinda bwo gupima ubukana bwa hydroxypropyl methyl seluloseHPMC?Iyo tugerageje ubwiza bwa selile.Kugirango hamenyekane neza ibisubizo by'ibizamini, hagomba kwitabwaho bidasanzwe ku bintu bine bikurikira.

1. Ibipimo byerekana igikoresho bigomba kuba byujuje ibisabwa n’amabwiriza agenga igenzura ry’igihugu.

Uwitekahydroxypropyl methyl seluloseigikoresho cyo gupima viscosity gikoreshwa mukizamini.Nibiba ngombwa (igikoresho gikoreshwa kenshi cyangwa muburyo bukomeye bwujuje ibyangombwa), hakorwa ikizamini cyo hagati kugirango harebwe niba imikorere yo gupima yujuje ibisabwa kandi ikosa rya coefficient riri murwego rwemewe, naho ubundi amakuru yukuri ntashobora kuboneka.

2. Witondere cyane ubushyuhe bwamazi apimwa.

Abakoresha benshi birengagiza ibi bakibwira ko ubushyuhe ntaho buhuriye.Ubushakashatsi bwacu bwerekana ko: iyo ubushyuhe butandukanijwe ni 0.5 ℃, gutandukana kwijimye kwamazi amwe arenze 5%.Gutandukana k'ubushyuhe bigira ingaruka zikomeye ku bwiza, ubushyuhe n'ubukonje.Kubwibyo, hagomba kwitonderwa bidasanzwe kugirango ubushyuhe bwamazi yapimwe hafi yubushyuhe bwagenwe, kandi kugirango bipime neza, nibyiza kutarenza 0.1 ℃.

3. Guhitamo ibikoresho bipima (umuyoboro wo hanze).

Kuri barikeli ebyiri zizunguruka viscometer, soma igitabo cyigikoresho witonze kandi uhuze na rotor (silinderi y'imbere) ukurikije.Silinderi yo hanze, naho ubundi ibisubizo byo gupima bizatandukana cyane.Kuri silinderi imwe izunguruka viscometer, radiyo ya silinderi yo hanze igomba kuba itagira iherezo.Ibipimo nyabyo bisaba ko diameter y'imbere ya silinderi yo hanze itari munsi yubunini runaka.Kurugero, viscometer ya NDJ-1 isaba icyuma gipima cyangwa icyuma kigororotse kitari munsi ya mm 70 z'umurambararo.Ubushakashatsi bwerekanye ko amakosa manini yo gupima ashobora kuvamo niba diameter y'imbere yubwato ari nto cyane, cyane cyane iyo rotor oya.1 ikoreshwa.

4, hitamo neza rotor cyangwa uhindure umuvuduko, kugirango agaciro ka gride yamashanyarazi hagati ya 20-90.

Ubu bwoko bwibikoresho bukoresha imvugo wongeyeho ibyasomwe, kandi guhuza gutuza no gusoma gutandukana bifite 0.5 gride.Niba gusoma ari bito cyane, byegereye gride 5, ikosa rigereranijwe rirashobora kurenga 10%.Niba rotor ikwiye yatoranijwe cyangwa gusoma byihuse ni 50, ikosa rigereranijwe rishobora kugabanuka kugeza 1%.Niba agaciro kerekana hejuru ya 90, urumuri rutangwa nisoko ni runini cyane, rukunda kunyerera no kwangiza umusatsi, bityo rero tugomba guhitamo neza rotor n'umuvuduko.

Uru rupapuro rutangiza ibibazo bikeneye kwitabwaho mugupima ubwiza bwa hydroxypropyl methyl selulose, twizeye ko ibivuzwe haruguru bishobora kugufasha kwipimisha.KIMA CHIMICALyubahiriza ihame rya "guhanga udushya, umukiriya ubanza, ubuziranenge bwa mbere".Igitekerezo cyo guteza imbere imishinga nugushingira ku kwizerana no kwiteza imbere igihe kirekire, guhora dushya ibikoresho nikoranabuhanga, kubungabunga ibidukikije n’iterambere ry’ikoranabuhanga rikomeye.Isosiyete yiteguye gufatanya n’ibicuruzwa byo mu gihugu n’amahanga byo mu rwego rwo hejuru ndetse n’inshuti igihe kirekire, ubufatanye buvuye ku mutima.
