Kupanga kwa HPMC pakumanga ndi utoto

Hydroxypropyl methylcellulose (HPMC mwachidule) ndi ofunika wosanganiza efa, amene si-ayoni madzi sungunuka polima, ndipo chimagwiritsidwa ntchito mu chakudya, mankhwala, tsiku makampani mankhwala, ❖ kuyanika, polymerization anachita ndi kumanga monga kubalalitsidwa kuyimitsidwa , thickening, emulsifying, stabilizing ndi zomatira, etc., ndipo pali kusiyana kwakukulu pamsika wapakhomo.

Chifukwa HPMC ali katundu kwambiri monga thickening, emulsification, kupanga filimu, zoteteza colloid, posungira chinyezi, adhesion, enzyme kukana ndi inertness kagayidwe kachakudya, chimagwiritsidwa ntchito zokutira, polymerization zimachitikira, zomangira, kupanga mafuta, nsalu, chakudya, mankhwala, Zoumba tsiku ndi tsiku, zida zamagetsi ndi mbewu zaulimi ndi madipatimenti ena.

Bzida zopangira

Pazomangira, HPMC kapena MC nthawi zambiri amawonjezedwa ku simenti, matope, ndi matope kuti apititse patsogolo zomangamanga ndi kusunga madzi.

HPMC angagwiritsidwe ntchito pa:

1).zomatira ndi caulking wothandizira kwa gypsum ofotokoza zomatira tepi;

2).Kumanga njerwa za simenti, matailosi ndi maziko;

3).stucco yopangidwa ndi pulasitiki;

4).pulasitala wopangidwa ndi simenti;

5).Mu chilinganizo cha utoto ndi utoto remover.

Zomatira kwa matailosi a ceramic

HPMC 15.3 magawo

Perlite 19.1 magawo

Ma amide amafuta ndi ma cyclic thio amaphatikiza magawo 2.0

Dongo 95.4 magawo

Zokometsera za silika (22μ) 420 magawo

450.4 magawo a madzi

Amagwiritsidwa ntchito mu simenti yomangidwa ndi njerwa, matailosi, miyala kapena simenti:

HPMC (digiri ya kubalalitsidwa 1.3) 0.3 magawo

Simenti ya Cattelan 100 magawo

Mchenga wa silika 50 magawo

50 magawo a madzi

Amagwiritsidwa ntchito ngati chowonjezera chopangira simenti yolimba kwambiri:

Simenti ya Cattelan 100 magawo

Asibesitosi 5 magawo

Polyvinyl mowa kukonza 1 gawo

Calcium silicate 15 magawo

Dongo 0,5 magawo

32 magawo a madzi

HPMC 0.8 magawo

Makampani opanga utoto

M'makampani opaka utoto, HPMC imagwiritsidwa ntchito kwambiri mu utoto wa latex ndi zigawo za penti zosungunuka ndi madzi monga chopangira filimu, thickener, emulsifier ndi stabilizer.

Kuyimitsidwa Polymerization ya PVC

Munda womwe umagwiritsa ntchito kwambiri zinthu za HPMC m'dziko langa ndi kuyimitsidwa kwa polymerization ya vinilu kolorayidi.Mu kuyimitsidwa polymerization wa vinilu kolorayidi, ndi kubalalitsidwa dongosolo mwachindunji zimakhudza khalidwe la mankhwala PVC utomoni ndi processing ndi mankhwala;imatha kusintha kukhazikika kwamafuta a utomoni ndikuwongolera kukula kwa tinthu (ndiko, kusintha kachulukidwe ka PVC).Kuchuluka kwa HPMC kumawerengera 0.025% ~ 0.03% ya zotulutsa za PVC.

The PVC utomoni wokonzedwa ndi apamwamba HPMC, kuwonjezera kuonetsetsa kuti ntchito akukumana muyezo dziko, alinso ndi katundu wabwino thupi, makhalidwe abwino tinthu ndi khalidwe kusungunula rheological kwambiri.

Omakampani

Makampani ena makamaka akuphatikizapo zodzoladzola, kupanga mafuta, zotsukira, zoumba m'nyumba ndi mafakitale ena.

Water sungunuka

HPMC ndi imodzi mwa ma polima osungunuka m'madzi, ndipo kusungunuka kwake m'madzi kumakhudzana ndi zomwe zili mugulu la methoxyl.Pamene zili methoxyl gulu ndi otsika, akhoza kusungunuka mu alkali wamphamvu ndipo alibe thermodynamic gelation mfundo.Ndi kuchuluka kwa methoxyl, imakhudzidwa kwambiri ndi kutupa kwamadzi komanso kusungunuka mu alkali wocheperako komanso wofooka wa alkali.Pamene methoxyl ili > 38C, imatha kusungunuka m'madzi, komanso imatha kusungunuka mu ma halogenated hydrocarbons.Ngati asidi nthawi anawonjezedwa kwa HPMC, HPMC mwamsanga kumwazikana m'madzi popanda kupanga insoluble caking zinthu.Izi makamaka chifukwa chakuti asidi periodic ali ndi magulu dihydroxyl mu ortho udindo pa omwazika glycogen.
