1. Ni ubuhe buryo nyamukuru bukoreshwa na selile?
HPMC ikoreshwa cyane mu bikoresho by'ubwubatsi, amatwi, ibisohokaga sinzoma, ubuvuzi, ubuvuzi, ibiryo, ubuhinzi, kwisiga, itabi n'izindi nganda. HPMC irashobora kugabanwa mubyiciro byinganda, amanota yibiribwa hamwe nicyiciro cya farumasi ukurikije porogaramu.
2. Hariho ubwoko bwinshi bwa selile, kandi ni irihe tandukaniro mu gukoresha?
HPMC irashobora kugabanywamo ubwoko bwa ako kanya (izina ryakira ryinshi Umugereka "s") na Ashyushye-Gushonga Ubwoko. Ibicuruzwa byubwoko ako kanya byatatanye vuba mumazi akonje kandi uzimire mumazi. Muri iki gihe, amazi adafite ubuyobe kuko HPMC yatatanye gusa mumazi gusa nta guseswa nyabyo. Ibyerekeye (Gukangurira) Iminota 2, viscolity yamahoro yiyongera buhoro buhoro, gukora virusi yacyo yera ya Colloid. Ibicuruzwa bishyushye, mugihe uhuye namazi akonje, ushobora gutatana vuba mumazi ashyushye kandi ukabura mumazi ashyushye. Iyo ubushyuhe bugabanutse ku bushyuhe runaka (ukurikije ubushyuhe bwa gel bwibicuruzwa), viscosity igaragara buhoro kugeza igihe ikorana na virusi ya Colloid.
3. Ni ubuhe buryo bwo gushonga kwa selile?
1). Moderi zose zirashobora kongerwaho kubikoresho byumye bivanze;
2). Iyo ikeneye kongerwaho ubushyuhe busanzwe igisubizo gisanzwe, nibyiza gukoresha ubwoko bwubukonje bukonje. Mubisanzwe bifata iminota 1-30 kugirango ubyimbye nyuma yo kongeramo (stur na stur)
3). Moderi isanzwe irashishikarizwa bwa mbere kandi ikwirakwizwa n'amazi ashyushye, hanyuma ashonga mumazi akonje nyuma yo gukangurira no gukonjesha;
4). Niba agglomeration ibaho mugihe cyo gusesa, ni ukubera ko gukangura bidahagije cyangwa icyitegererezo gisanzwe kirimongewe mumazi akonje. Muri iki gihe, bigomba gusuzumwa vuba. the
5). Niba bubbles yakozwe mugihe cyo guseswa, irashobora gusigara amasaha 2-12 (igihe cyihariye kigenwa nigisubizo cyikiruhuko) cyangwa gukurwaho no kurakara, nibindi, hamwe numukozi ukwiye wongeyeho. the
4. Nigute wacira urubanza ubwiza bwa selile kandi byimazeyo?
1) Uwawe, nubwo umweru udashobora kumenya niba HPMC yoroshye gukoresha, kandi niba abakozi ba Whiteen bongeyeho mubikorwa, ariko bikagira ingaruka kumiterere yayo, ariko ibyinshi mubicuruzwa byiza bifite channene nziza.
2) Guheza: Ibyiza bya HPMC muri rusange bifite mesh yonyine na Mesh 100, 120 ni bike, byiza cyane.
3) Gufungura urumuri: Nyuma ya HPMC ishyirwa mumazi kugirango ikore umucyo wa Colloid, reba umucyo. Ibyiza byoherezwa, nibyiza, byerekana ko hari ibingo bitarenzeho, kandi koherezwa kwabatwara guhagarika muri rusange ni byiza. , Reacttal ya horizontal ni mubi, ariko ntibisobanura ko ubwiza bwa reactique biruta iy'umugozi utambitse, kandi haribintu byinshi byo kumenya ubuziranenge bwibicuruzwa.
4) Imbaraga zikomeye: nini nini nini, nziza cyane. Isumbuye nini cyane, hejuru hydroxyPropyl ibirimo ibicuruzwa. Isumbuye ya hydroxyPropyle, ni byiza kugumana amazi.
5. Ni ubuhe buryo bwa selile ifu?
Umubare wa HPMC ukoreshwa mubikorwa bifatika bigira ingaruka kumikino, ubushyuhe, ubuziranenge bwa calcium ya hotcium yaho, formula yifu ya proceder hamwe nubwiza busabwa nabakiriya. Hariho itandukaniro ahantu hatandukanye, muri rusange, ni hagati ya 4-5.
6. Ni ubuhe buryo bukwiye bwa selile?
Mubisanzwe, ifu 100.000 ifu irahagije, kandi ibisabwa muri minisiteri biri hejuru, kandi bisaba 150,000 kugirango byoroshye gukoresha. Byongeye kandi, imikorere yingenzi ya HPMC ni ifungwa ry'amazi, ikurikirwa no kubyimba. Mu ifu ya Putty, igihe cyose ihohoterwa rishingiye ku mazi ari ryiza kandi ko bigaragara ko ari hasi (7-8), birashoboka. Birumvikana ko hejuru cyane viscosiya, gusubizwa amazi meza. Iyo visosity irenze 100.000, viscometity nta ngaruka igira uruhare mu kugumana amazi. binini.
7. Ni ibihe bipimo nyamukuru bya tekiniki bya selile?
HydroxyPropyl Ibirimo
Methyl
vicosity
Ivu
Gutakaza Kuma
8. Ni ibihe bikoresho by'ibanze bya selile?
Ibikoresho by'ibanze bya HPMC: Ipamba rinoze, Methyl Chloride, ibyatsi bya proplone, soda ya caustic soda, nibindi.
9. Niyihe mikorere nyamukuru yo gusaba selile ipamba? Hari reaction iyo ari yo yose?
Muri ifu ya Putty, igereranya inshingano eshatu zo kwinuba, kugumana amazi no kubaka. Kwinginga, selile irashobora kubyimba guhagarika, komeza umwambaro hejuru no hasi, kandi urwanye ubwoba. Ihagarikwa ry'amazi: Kora ifu ya LIPTY yumye buhoro, kandi ifashe akajagari iz kwitwara munsi y'ibikorwa by'amazi. Kubaka: Ubugari bufite ingaruka zo gusiga, ishobora gutuma ifu ya LETY igira kubaka neza. HPMC ntabwo yitabira imiti iyo ari yo yose, ahubwo igira uruhare runini gusa.
10. Cekwi niko selile itari ionic ether, none bidafite iki?
Mu Masezerano y'Abalayini, ibintu bya inert ntibitabira imiti.
CMC (CarboxyMethyl Cellulose) ni selile ya catic, bityo izahinduka umuyoboro wibishyimbo iyo uhuye na calcium ivu.
11 Ubushyuhe bwa GEL ni iki?
Ubushyuhe bwa GEL bwa HPMC bufitanye isano nuburyo bwabwo, butoya ibirimo, hejuru yubushyuhe bwa gel.
12. Hari isano iri hagati yo gutakaza ifu ya prowder ifu na selile?
Hariho umubano! ! ! Ni ukuvuga, kugumana amazi mabi bizatera igihombo cya powder (ibikubiye mubikoresho nka ash, calcium ndende, na sima, ubushyuhe bwubwubatsi, hamwe nurukuta rwose bizagira ingaruka).
13. Ni irihe tandukaniro riri hagati y'amazi akonje ako kanya kandi ashyushye ashyushye muri gahunda yo gukora?
Ubwoko bw'amazi akonje ako kanya bwa HPMC buvurwa hamwe na Glyoxal, kandi ikwirakwiza vuba mumazi akonje, ariko ntabwo rwose ishonga. Gusa birashonga mugihe ubukuru bwiyongera. Ubwoko butandukanye bwashonze ntabwo buvurwa na glegoxal. Niba umubare wa Glyoxal ari munini, gutatanya bizahita byihuta, ariko viscosity iziyongera buhoro, kandi niba amafaranga ari nto, ibinyuranye nabyo bizaba ukuri.
14. Kuki selile ifite impumuro?
HPMC yakozwe nuburyo bworoshye bukoresha toluene na isopropanol nkuko bitanga. Niba gukaraba atari byiza cyane, hazabaho impumuro zisigaye. (Kuboneza ubudanone ninzira yingenzi ya odor)
15. Nigute wahitamo selile ikwiye kubikorwa bitandukanye?
PATTY FEWLER: bisaba ko ugumana amazi menshi, koroshya kubaka neza
Minisiteri isanzwe ishingiye kuri sima ishingiye ku miburo: bisaba ko ugumana amazi menshi, kurwanya ubushyuhe bwinshi, hamwe na virusi nyayo
Gushyira mu bikorwa kole yubwubatsi: Ibicuruzwa ako kanya hamwe na viscosity. (amanota asabwa
Mypsum Mortar: Kugumana amazi menshi, Hagati no hasi kandi nkeya, ubushyuhe buhita bwiyongera
16. Ni irihe zina rindi kuri selile?
Yitwa HPMC cyangwa MHPC alias Hyppimellose, hydroxypropyl methyl ether.
.
Muri Prowder ifu, HPMC igira uruhare rutatu yo kubyimba, kugumana amazi no kubaka. Impamvu zo guturwa ni:
1. Amazi menshi yongeyeho.
2. Igice cyo hasi ntabwo cyumye, gusa gikuraho ikindi gice hejuru, kandi biroroshye kubyibumba.
18. Ni irihe tandukaniro riri hagati ya selile na MC:
MC ni methyl selile, ikozwe muri selile yanga ipamba itunganijwe hamwe na alkali, ukoresheje methane metloride nkabakozi bahura, kandi ugabanye urukurikirane. Mubisanzwe, urwego rwo gusimburwa ni 1,6-2.0, kandi kwikebana biratandukanye na impamyabumenyi zitandukanye zo gusimburwa. Bitandukanye, ntabwo ari ibya Nolic.
. Mubisanzwe, niba amafaranga yongeyeho ari manini, igorofa ni nto, kandi viscometity nini, igipimo cyo kugumana amazi ni kinini. Muri bo, umubare wongeyeho ufite ingaruka zikomeye ku gipimo cy'amazi muntu. Urubyiruko ntabwo ruringaniye ku gipimo cy'amazi. Igipimo cyo gusebanya cyane cyane giterwa no hejuru ya selile. Urwego rwo guhindura no gutsindira. Muri aya makuru yakane yavuzwe haruguru, urugero rw'amazi ya Methyl selile na Jinshuiqiao selile ni hejuru.
(2) methylcellsellse irashonga mumazi akonje, kandi bizaba bigoye gushonga mumazi ashyushye. Igisubizo cyacyo gihamye cyane murwego rwa PH = 3-12. Ifite ubuso bwiza hamwe nigitako, nibindi. Iyo ubushyuhe iyo ubushyuhe bwa gelala bwagerwaho, pelation bizabaho.
. Mubisanzwe, hejuru yubushyuhe, igipimo cyo kugumana amazi. Niba ubushyuhe bwa minisiteri burenze dogere 40, kugumana amazi ya methyl selile bizagabanuka cyane, bizagira ingaruka zikomeye kubanya minisiteri.
. Adhesion hano bivuga imbaraga zifatika zumvaga hagati yigikoresho cyumukozi hamwe nurukuta, ni ukuvuga kurwanya minisiteri. Kubungabunga ni byinshi, kurwanya imisiteri ari nini, kandi imbaraga zisabwa n'abakozi mu buryo bwo gukoresha nacyo ni kinini, kandi imikorere y'ubwubatsi ya minisiteri irakennye.
