Ni ubuhe buryo nyamukuru ikoreshwa rya hydroxyproppopyl methylcellse?

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.

2Umukunzi wawe Methylcellse igabanijwemo ubwoko bwinshi, kandi ni irihe tandukaniro riri mukoresha?

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.

Nibihe buryo bwo kuvugurura bwa HydroxyPropyl Methylcellse?

1) moderi zose zirashobora kongerwaho kubikoresho muburyo bwumye;
2) mugihe gikeneye kongerwaho ubushyuhe busanzwe
3) Icyitegererezo gisanzwe kirakangurwa kandi cyatatanye amazi ashyushye, noneho birashobora guseswa nyuma yo kongera amazi akonje no gukonja;
4) Niba agglomeration no gupfunyika bibaho mugihe cyo gusesa, ni ukubera ko gukangura bidahagije cyangwa icyitegererezo gisanzwe cyongeweho amazi akonje. Muri iki gihe, bigomba gusuzumwa vuba. the
5) Niba bubbles yakozwe mugihe cyo guseswa, irashobora gusigara amasaha 2-12 (igihe cyihariye kigenwa nigisubizo cyimisoro) cyangwa gukurwaho no kurakara, nibindi, cyangwa umubare wabigenewe. the

4 Uburyo bwo Gucira urubanza Ubwiza bwa HydroxyPropyl Methylcellse Gusa kandi Byihuse?

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 hydroxypropyl methylcellse mu ifu ya Putty?

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.

Ni ubuhe buryo bukwiye bwa HydroxyPropyl Methylcellse?

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 ubuhe buryo nyamukuru tekinike ya hydroxypropyl methylcellse?

HydroxyPropyl Ibirimo

8 Ni ibihe bikoresho nyamukuru bya hydroxyproppopyl methylcellse?

Ibikoresho by'ibanze bya HPMC: Ipamba rinoze, methyl chloride, ibyatsi bya proplone, ibindi bikoresho fatizo, acide Soda, aside.

9 Ni ikihe gikorwa nyamukuru cyo gushyira mu bikorwa hydroxyproppopyl methylcellse mu ifu ya Putty, kandi bibaho bibaho?

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 HydroxyPropyl Methylcellse niko Cellulose utari Uonic, 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 Ni ubuhe bushyuhe bwa GAL bwa hydroxypropyl methylcellse bijyanye?

Ubushyuhe bwa GEL bwa HPMC bufitanye isano nuburyo bwabwo, butoya ibirimo, hejuru yubushyuhe bwa gel.

12 Hari umubano uri hagati yigitonyanga cyifu ya prowder na hydroxypropyl methylcellse?

Hariho umubano! ! ! Nibibazo byogumana amazi ya HPMC, bizatera gutakaza ifu.

13 Ni irihe tandukaniro riri hagati y'amazi akonje ako kanya kandi ashyushye ashyushye ya hydroxypropyl methylcellse mu buryo bukora?

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 Umunuko wa hydroxypropyl methylcellse?

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 Gukoresha Bitandukanye, Nigute wahitamo HydroxyPropyl Methylcellse?

PATTY FEWLER: bisaba ko ugumana amazi menshi, koroshya kubaka neza
Minisiteri isanzwe ishingiye kuri sima ishingiye ku busanzwe: bisaba ko ugumana amazi menshi, kurwanya ubushyuhe bwinshi, hamwe na virusi nyayo (
Gushyira mu bikorwa kole yubwubatsi: Ibicuruzwa ako kanya hamwe na viscosity.
Mypsum Mortar: Kugumana amazi menshi, Hagati no hasi kandi nkeya, ubushyuhe buhita bwiyongera

Niki alias ya 8 hydroxypropyl methylcellse?

Yitwa HPMC cyangwa MHPC alias Hyppimellose, hydroxypropyl methyl ether.
17 Gushyira mu bikorwa hydroxyPropyl methylcellse mu ifu ya Putty, niyihe mpamvu yo kuvura ikirere muri ifu ya Putty?

Muri Prowder ifu, HPMC igira uruhare rutatu yo kubyimba, kugumana amazi no kubaka. Impamvu zo guturwa ni:

(1) Amazi menshi yongeyeho.
.

18 Ni irihe tandukaniro riri hagati ya hydroxypropyl methylcellse 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 erebire yavuzwe haruguru, Methyl selile na hydroxypropyl methyl Methyl ifite ibiciro byamazi menshi.
(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 imiti ya minisiteri ni binini, kandi imbaraga zisabwa n'abakozi mu gihe cyo gukoresha nanini, kandi iyuba ry'abantu ni umukene.
