Hydroxypropyl methyl selulose igabanijwemo ubwoko butandukanye, kandi ni irihe tandukaniro mugukoresha?
HPMC irashobora kugabanwa muburyo bwihuse kandi bushyushye.Ibicuruzwa ako kanya bikwirakwira vuba mumazi akonje bikabura mumazi.Muri iki gihe, amazi ntagira ubukonje, kubera ko HPMC ikwirakwizwa mu mazi gusa kandi ntishonga.Nyuma yiminota igera kuri 2 (gukurura), ubwiza bwamazi bwiyongera buhoro buhoro, bigakora colloid yera yera igaragara.Ibicuruzwa bishyushye birashobora gukwirakwira vuba mumazi ashyushye bikabura mumazi ashyushye mugihe byegeranijwe mumazi akonje.Iyo ubushyuhe bugabanutse ku bushyuhe runaka (ukurikije ubushyuhe bwa geli y'ibicuruzwa), ubwiza bugaragara buhoro buhoro kugeza igihe havutse ibara ryitwa viscous colloid.
Nigute ushobora gusuzuma ubwiza bwa hydroxypropyl methyl selulose byoroshye kandi byihuse?
Umweru.Nubwo umweru udashobora kumenya niba HPMC yoroshye gukoresha, kandi niba ibikoresho byera byongewe mubikorwa byo kubyara, bizagira ingaruka kumiterere yabyo, ibicuruzwa byiza byinshi bifite umweru mwiza.
Ubwiza: ubwiza bwa HPMC muri rusange ni mesh 80 na mesh 100, naho mesh 120 ni mike.Nibyiza, nibyiza.
Itumanaho ryoroheje: HPMC imaze gushyirwa mumazi kugirango ikore colloid ibonerana, reba itara ryayo.Ninshi kohereza urumuri, nibyiza.Bisobanura ko muri yo harimo ibintu bike bidashonga.Ihererekanyabubasha rya vertical reaction ni byiza muri rusange, kandi irya reaction ya horizontal ni mbi.Ariko rero, ntibisobanura ko ubwiza bwa reaction ya vertical iruta iy'ibikorwa bya horizontal.Hariho ibintu byinshi byerekana ubwiza bwibicuruzwa.
Imbaraga rukuruzi: nini nini nini nini nini, iremereye, nibyiza.Mubisanzwe, ni ukubera ibiri muri hydroxypropyl muri yo ni byinshi.Niba ibirimo hydroxypropyl ari byinshi, kubika amazi nibyiza.

ni ubuhe buryo bwo gusesa hydroxypropyl methyl selulose?
Moderi zose zirashobora kongerwaho ibikoresho muburyo bwo kuvanga byumye;
Iyo bikenewe kongerwaho muburyo butaziguye mumazi yubushyuhe bwicyumba, nibyiza gukoresha ubwoko bukwirakwiza amazi akonje.Mubisanzwe, irashobora kubyimba muminota 10-90 nyuma yo kongeramo (gukurura)
Moderi isanzwe irashobora gushonga nyuma yo kuvanga no gutatanya namazi ashyushye, ukongeramo amazi akonje, gukurura no gukonjesha;
Niba guteka no gupfunyika bibaye mugihe cyo gusesa, biterwa no kuvanga bidahagije cyangwa moderi zisanzwe zongerwaho mumazi akonje.Muri iki gihe, bigomba gukangurwa vuba.
Niba ibibyimba byabyaye mugihe cyo guseswa, birashobora gukurwaho uhagaze kumasaha 2-12 (igihe cyihariye giterwa no guhuza igisubizo), vacuuming, igitutu nubundi buryo, cyangwa wongeyeho urugero rukwiye rwa defoamer.
Ni uruhe ruhare hydroxypropyl methyl selulose igira mu gukoresha ifu ya putty, kandi niba hari chimie?
Ifu ya putty, ikina inshingano eshatu: kubyimba, gufata amazi no kubaka.Kubyimba, selile irashobora kwiyongera, gukina uruhare rwo guhagarikwa, kugumisha igisubizo hejuru no hepfo, no kurwanya kugabanuka.Kubika amazi: kora ifu ya putty yumye gahoro gahoro, kandi ufashe calcium ya lime gukora mugihe cyamazi.Ubwubatsi: selile ifite ingaruka zo gusiga, zishobora gutuma ifu ya putty igira imikorere myiza.HPMC ntabwo yitabira imiti iyo ari yo yose, ariko igira uruhare gusa.
Ubushyuhe bwa gel bwa hydroxypropyl methyl selulose bufitanye isano niki?
Ubushyuhe bwa gel bwa HPMC bufitanye isano na vitamine.Hasi ya mikorerexyl, nubushyuhe bwa gel.
hari isano hagati yo guta ifu ya putty na hydroxypropyl methyl selulose?
Ni ngombwa !!!HPMC ifite amazi mabi, bizatera gutakaza ifu.
Gukoresha hydroxypropyl methyl selulose muri poro ya putty, niyihe mpamvu itera ibibyimba mu ifu ya putty?
HPMC ifite uruhare runini mu ifu yuzuye: kubyimba, gufata amazi no kubaka.Impamvu zibibyimba nizi zikurikira:
Amazi menshi yongeyeho.
Niba usibye ikindi gice kumurongo wo hasi mbere yuko cyuma, biroroshye kandi kubyimba.
