Kureba vuba kuri hydroxypropyl methylcellulose HPMC
Imwe, niyihe mikoreshereze nyamukuru ya hydroxypropyl methyl selulose?
HPMC YAKORESHEJWE MU BIKORWA BYUBAKA, impuzu, ibisigazwa bya sintetike, ububumbyi, ubuvuzi, ibiryo, imyenda, ubuhinzi, amavuta yo kwisiga, itabi nizindi nganda.HPMC irashobora kugabanywa mubyiciro byinganda, urwego rwibiryo nu rwego rwa farumasi ukurikije imikoreshereze yabyo.
Babiri, hydroxypropyl methyl selulose igabanijwemo ubwoko buke, muritandukaniro irihe?
HPMC irashobora kugabanywa muburyo bwihuse (ingero yo mu cyiciro “S”) hamwe nubwoko bushyushye, ibicuruzwa byihuse, mumazi akonje bikwirakwira vuba, bikabura mumazi, muriki gihe amazi ntagira ububobere, kuko HPMC ikwirakwizwa mumazi gusa , nta guseswa nyabyo.Hafi (stir) muminota 2, ubwiza bwamazi bwiyongera buhoro buhoro, bikora colloid isobanutse neza.Ibicuruzwa bishyushye bishyushye, mumazi akonje, birashobora gukwirakwira vuba mumazi ashyushye, bikabura mumazi ashyushye, nkubushyuhe bukamanuka kubushyuhe runaka (ukurikije ubushyuhe bwa gel bwibicuruzwa), ubukonje bugaragara buhoro buhoro, kugeza igihe habaye ibibyimba bibonerana. colloid.
Bitatu, hydroxypropyl methyl selulose uburyo bwo gukemura bufite iki?
1. Moderi zose zirashobora kongerwaho ibikoresho muburyo bwo kuvanga byumye;
2, ukeneye kongerwaho muburyo butaziguye ubushyuhe bwamazi asanzwe, nibyiza gukoresha ubwoko bukwirakwiza amazi akonje, nyuma yo kongeramo muri rusange muminota 10-90 kugirango ubyibushye (gukurura, gukurura, gukurura)
3. Icyitegererezo gisanzwe gikwirakwizwa no kuvanga n'amazi ashyushye, hanyuma kigashonga wongeyeho amazi akonje nyuma yo gukurura no gukonja.
4. Niba ibintu byo guteka no gupfunyika bibaho mugihe cyo gushonga, ni ukubera ko kuvanga bidahagije cyangwa moderi isanzwe yongewe kumazi akonje.Muri iki gihe, bigomba gukangurwa vuba.
5. Niba ibibyimba byakozwe mugihe byashongeshejwe, birashobora gusigara amasaha 2-12 (igihe cyihariye kigenwa nuburyo bwo gukemura) cyangwa gukurwaho no gukuramo vacuum, igitutu nubundi buryo, hamwe nuburyo bukwiye bwa antifoaming irashobora kandi kongerwamo.
Bane, nuburyo bworoshye kandi bwihuse bwo kumenya igihagararo cyangwa kugwa kwa hydroxypropyl methyl selulose?
1, umweru, umweru nubwo bidashobora kumenya niba HPMC ari nziza, kandi niba yongewemo mubikorwa byo kwera, bizagira ingaruka kumiterere yabyo, ariko, ibicuruzwa byiza ahanini byera nibyiza.
2, ubwiza: HPMC ubwiza muri rusange mesh 80 na mesh 100, 120 munsi, ibyiza nibyiza nibyiza.
3, ihererekanyabubasha: HPMC mumazi, ikora colloid ibonerana, reba itumanaho ryayo, uko binini byinjira mubyiza, sobanura ibidashobora gukemuka imbere, icyayi gihagaze neza kuri dogere muri rusange ni byiza, bizohereza bimwe mubitereko bitambitse, ariko ntishobora gusobanura ihagarikwa ryikariso ihagaze neza kuruta umusaruro wibinyobwa, hari ibintu byinshi byerekana ubwiza bwibicuruzwa.
4, igipimo: uko igipimo kinini, kiremereye ni cyiza, kuruta icy'ingenzi, muri rusange kubera ko ibirimo hydroxypropyl ari byinshi, hydroxypropyl iri hejuru, noneho kubika amazi bikaba byiza.
Bitanu, hydroxypropyl methyl selulose mubwinshi bwa poro ya putty?
HPMC muburyo nyabwo bwo gukoresha dosiye, ukurikije ikirere cy’ikirere, ubushyuhe, ubwiza bwa calcium ya kalisiyumu, ifu yifu ya putty hamwe nibisabwa kubakiriya byubwoko butandukanye, kandi hariho itandukaniro hirya no hino, muri rusange, hagati ya kg 4-5.
Gatandatu, hydroxypropyl methyl selulose viscosity nibyiza cyane?
Kurambirwa NUBUBASHA BW'ABANA NIBISANZWE Ibihumbi 100 BYIZA, IBISABWA MORTAR BIMWE MU BINTU, USHAKA ibihumbi 150 KUBA BYIZA GUKORESHWA GUSA, kandi, HPMC uruhare runini ni ukubika amazi, ubutaha ni mwinshi.Mu ifu ya putty, mugihe cyose gufata amazi ari byiza, viscosity iba mike (7-8), birashoboka kandi, byanze bikunze, viscosity nini, gufata amazi ugereranije nibyiza, mugihe ububobere burenga 100.000 , ibishishwa ntacyo bigira ku kubika amazi.
Birindwi, ni ibihe bimenyetso nyamukuru bya tekinike ya hydroxypropyl methyl selulose?
Hydroxypropyl ibirimo
Ibirimo Methyl
ububobere
ivu
Kugabanya ibiro byumye
Umunani, ni ibihe bikoresho by'ibanze bya hydroxypropyl methyl selulose?
Ibikoresho by'ibanze bya HPMC: ipamba itunganijwe, chloromethane, okiside ya propylene, ibindi bikoresho fatizo, ibinini bya alkali, aside toluene.
Icyenda, hydroxypropyl methyl selulose mugukoresha ifu ya putty, uruhare runini, yaba imiti?
Ifu yuzuye, ifite uruhare runini: kubyimba, gufata amazi no kubaka.Kubyimba, selile irashobora kubyimbagana kugirango ikine ihagarikwa, kugirango igisubizo cyo gukomeza imyenda imwe hejuru no munsi yuruhare rumwe, anti flow amanitse.Kubika amazi: kora ifu ya putty yumye gahoro gahoro, calcium ivu ya calcium ikora munsi yamazi.Ubwubatsi: Cellulose ifite amavuta yo gusiga, irashobora gukora ifu ya putty ifite ubwubatsi bwiza.HPMC ntabwo yitabira imiti iyo ari yo yose, igira uruhare gusa.
Hydroxypropyl methyl selulose ntabwo ari ionic selulose ether, noneho non-ionic niki?
Muri rusange, ibintu bya inert ntabwo bigira uruhare mubitekerezo byimiti.
CMC (carboxymethyl selulose) ni selile cationic selile, bityo guhura na calcium yumukara bizahinduka ibishyimbo bya curd.
11. Ubushyuhe bwa gel bwa hydroxypropyl methylcellulose bufitanye isano niki?
Ubushyuhe bwa gel bwa HPMC bufitanye isano nibirimo.Hasi ya mikorerexyxy, nubushyuhe bwa gel.
Ifu cumi na zibiri, ifu yifu na hydroxypropyl methyl selile ntifitanye isano?
Ni ngombwa !!HPMC ni kubika amazi nabi, bizatera ifu.
13. Ni irihe tandukaniro riri hagati yumuti ukonje wihuse nigisubizo gishyushye cya hydroxypropyl methyl selulose mugikorwa cyo kubyara?
Ubwoko bwa HPMC bukonje bwamazi ni nyuma yo kuvura hejuru ya glyoxal, mumazi akonje akwirakwira vuba, ariko ntabwo ashonga rwose, ibishishwa hejuru, birashonga.Ubwoko bwokubura ubushyuhe ntabwo bwakorewe hejuru ya glyoxal.Ingano ya glyoxal nini, gutatanya birihuta, ariko ibishishwa biratinda, ingano ni nto, kurundi ruhande.
14, hydroxypropyl methyl selulose impumuro nziza nigute wasubiza inshingano?
HPMC yakozwe nuburyo bwa solvent ikozwe muri toluene na alcool ya isopropyl nkibishishwa.Niba gukaraba atari byiza cyane, hazabaho uburyohe busigaye.(Kubogama kutabogamye ninzira yingenzi yumunuko)
15, imikoreshereze itandukanye, nigute ushobora guhitamo hydroxypropyl methyl selulose?
Ifu yuzuye: ibisabwa byo gufata amazi menshi, ubwubatsi bwiza bworoshye (icyiciro gisabwa: 7010N)
Isima isanzwe ishingiye kuri sima: kugumana amazi menshi, kurwanya ubushyuhe bwinshi, ubukonje bwihuse (icyiciro gisabwa: HPK100M)
Gukoresha kole yubaka: ibicuruzwa ako kanya, ubwiza bwinshi.(Ikirango cyasabwe: HPK200MS)
Gypsum mortar: kubika amazi menshi, ubukonje buciriritse kandi buke, ubwiza bwako kanya (icyiciro gisabwa: HPK600M)
16, hydroxypropyl methyl selulose alias ni iki?
HPMC cyangwa MHPC alias hydroxypropyl methyl selulose, selile hydroxypropyl methyl ether.
Cumi na birindwi, hydroxypropyl methyl selulose mugukoresha ifu ya putty, ifu ya putty bubble niyihe mpamvu?
HPMC mu ifu yuzuye, kina inshingano eshatu zo kubyimba, gufata amazi no kubaka, impamvu yo kubyimba:
1. Amazi menshi yongeyeho.
2. Hasi ntabwo yumye, hejuru yikindi gice cyo gusiba, nacyo cyoroshye kubyimba.
Umunani, hydroxypropyl methyl selulose na MC itandukaniro irihe:
MC ni methylcellulose, ikozwe mu ipamba itunganijwe nyuma yo kuvura alkali na methane chloride nka mitiweli ya etherification binyuze muburyo butandukanye bwo gukora selile.Mubisanzwe, urwego rwo gusimburwa ni 1.6-2.0, kandi gukomera kwinzego zitandukanye zo gusimburana nabyo biratandukanye, ibyo bikaba ari selile ionic selile.
.Muri rusange, niba umubare wongeyeho ari munini, ubwiza ni buto kandi ubwiza ni bunini, igipimo cyo gufata amazi ni kinini.Ingano yo kongeramo igira uruhare runini ku kigero cyo gufata amazi, kandi ubukonje ntaho buhuriye n’igipimo cyo gufata amazi.Umuvuduko wo gusesa ahanini biterwa nuburinganire bwo hejuru bwa selile ya selile na selile nziza.Muri selile yavuzwe haruguru ether methyl selulose na hydroxypropyl methyl selulose igipimo cyo gufata amazi kiri hejuru.
. ubushyuhe bwa gelation, ibintu bya gelation bizabaho.
.Niba ubushyuhe bwa minisiteri burenze dogere 40, kugumana amazi ya methyl selulose bizaba bibi cyane, bikagira ingaruka zikomeye ku iyubakwa rya minisiteri.
(4) Methyl selulose igira uruhare rugaragara mukubaka no gufatira minisiteri.Hano, gufatira hamwe bivuga imbaraga zifatika zumvwa hagati yigikoresho cya daub cyabakozi hamwe nuruzitiro rwurukuta, ni ukuvuga ubukana bwa minisiteri.Umutungo ufatika ni munini, kurwanya shear ya minisiteri ni nini, kandi imbaraga zisabwa n'abakozi mugikorwa cyo gukoresha nazo nini, bityo imitungo yo kubaka minisiteri ikennye.
