Choyamba, kalasi ya guluu zomangamanga ayenera kuganizira zopangira.Chifukwa chachikulu chakusanjikiza kwa guluu womanga ndi kusagwirizana pakati pa acrylic emulsion ndi hydroxypropyl methylcellulose (HPMC).Kachiwiri, chifukwa chosakwanira nthawi yosakaniza;palinso kukhuthala kwa guluu womanga.Pomanga guluu, muyenera kugwiritsa ntchito instant hydroxypropyl cellulose (HPMC), chifukwa HPMC amangomwazikana m'madzi, samasungunuka kwenikweni.Pambuyo pa mphindi ziwiri, kukhuthala kwamadzimadzi kumawonjezeka pang'onopang'ono, kutulutsa njira yowonekera bwino ya viscous colloidal.Mankhwala osungunuka otentha, akagwidwa ndi madzi ozizira, amatha kumwazikana m'madzi otentha ndikutha m'madzi otentha.Kutentha kumatsika mpaka kutentha kwina, kukhuthala kumawonekera pang'onopang'ono mpaka njira yowonekera bwino ya viscous colloidal imapangidwa.Mlingo wovomerezeka wa hydroxypropyl methylcellulose (HPMC) pomanga guluu ndi 2-4KG.
Hydroxypropyl methylcellulose (HPMC) ili ndi mphamvu zokhazikika zomangira zomatira, ndipo imakhala ndi zotsatira zabwino kwambiri zochotsa mildew ndi kutseka madzi, ndipo sizidzakhudzidwa ndi kusintha kwa pH mtengo.Kukhuthala kungagwiritsidwe ntchito pakati pa 100,000 s ndi 200,000 s.Pakupanga, kukwezeka kwa viscosity kumakhala bwino.Viscosity ndi inversely molingana ndi chomangira compressive mphamvu.The apamwamba mamasukidwe akayendedwe, m'munsi mphamvu compressive.Nthawi zambiri, kukhuthala kwa 100,000 s ndikoyenera.
Sakanizani CMC ndi madzi ndikupanga phala lamatope kuti mugwiritse ntchito mtsogolo.Mukayika phala la CMC, onjezerani madzi ozizira pang'ono ku thanki ya batching ndi makina oyambitsa.Pamene makina oyambitsa ayambika, pang'onopang'ono ndi mogawaniza kuwaza carboxymethyl cellulose mu batching thanki, ndipo pitirizani kusonkhezera, kuti carboxymethyl cellulose ndi madzi zisakanizike kwathunthu, ndipo carboxymethyl cellulose kusungunuka kwathunthu.Pamene Kutha CMC, nthawi zambiri kofunika kumwazikana wogawana ndi kusakaniza mosalekeza, kuti bwino "kupewa clumping ndi agglomeration wa CMC pambuyo kukumana madzi, ndi kuchepetsa vuto la CMC kuvunda" ndi kuonjezera Kutha mlingo wa CMC. .
Nthawi yosakaniza si yofanana ndi nthawi yoti CMC isungunuke kwathunthu.ndi 2 matanthauzo.Nthawi zambiri, nthawi yosakanikirana ndi yayifupi kwambiri kuposa nthawi yoti CMC isungunuke kwathunthu, zimatengera mwatsatanetsatane.Maziko kuweruza nthawi kusanganikirana ndi pamene CMC ndi uniformly omwazika m'madzi popanda zoonekeratu apezeka, ndi kusanganikirana akhoza anasiya, kuti CMC ndi madzi akhoza kudutsa wina ndi mzake pansi pa zinthu malo amodzi deta.Pali zifukwa zingapo zodziwira nthawi yofunikira kuthetsedwa kwathunthu kwa CMC:
(1) CMC ndi madzi zimaphatikizidwa kwathunthu, ndipo palibe zida zolekanitsa zamadzimadzi zolimba pakati pawo;
(2) Phala losakanikirana ndilofanana bwino komanso lachibadwa, lokhala ndi malo osalala komanso osalala;
(3) Phala losakanikirana liribe mtundu ndipo limakhala loonekeratu, ndipo palibe tinthu tating'onoting'ono mu phala.Zimatenga maola 10 mpaka 20 kuchokera nthawi yomwe CMC imayikidwa mu thanki yosakaniza ndikusakaniza ndi madzi mpaka itasungunuka kwathunthu.
