Porogaramu ya HPMC mumyenda yinganda

Hydroxypropyl methylcellulose (HPMC) ni amazi ya elegitoronike ya ionic selulose ether ikoreshwa cyane mubikoresho byubwubatsi, imiti yimiti, ibiryo, ibicuruzwa byita kumuntu hamwe no gutwikira. Mu nganda no gusiga amarangi, HPMC yabaye inyongera yingenzi kubera imiterere yihariye yumubiri nubumara. Igikorwa cyacyo nyamukuru nugukora nkibyimbye, stabilisateur, umukozi ukora firime hamwe numukozi ushinzwe kugenzura imiterere ya rheologiya kugirango atezimbere imikorere, ihagarikwa ryububiko hamwe nubwiza bwikoti ryamabara.

1. Ibiranga shingiro bya HPMC

HPMC nuruvange rwabonetse muguhindura imiti ya selile. Ifite ibintu byingenzi bifatika byumubiri nubumashini, bituma ikoreshwa cyane mumyenda yinganda no gusiga amarangi:

Amazi meza: HPMC ifite imbaraga zo gukemura neza mumazi akonje, ikora igisubizo kibonerana gifasha kunoza ubwiza bwirangi.

Ubushyuhe bwa Thermal: Ku bushyuhe runaka, HPMC izakora gel hanyuma isubire kumuti nyuma yo gukonja. Ibi biranga bituma itanga imikorere myiza yuburyo bwiza bwubwubatsi.

Ibintu byiza byo gukora firime: HPMC irashobora gukora firime ikomeza mugihe irangi ryumye, bigateza imbere no kuramba.

Igihagararo: Ifite imbaraga nyinshi kuri acide, shingiro na electrolytite, ikemeza ko igifuniko gihamye mububiko butandukanye no gukoresha ibihe.

2. Imikorere yingenzi ya HPMC mumyenda yinganda

2.1

Mu nganda zikora inganda, ingaruka za HPMC ni ngombwa cyane. Igisubizo cyacyo gifite ubukonje bwinshi kandi bwiza bwogosha, ni ukuvuga mugihe cyo gukurura cyangwa gusiga amarangi, ibishishwa bizagabanuka byigihe gito, bityo byorohereze kubaka irangi, kandi ibishishwa bizakira vuba nyuma yubwubatsi buhagaritswe kugirango birinde irangi Kuva. Uyu mutungo uremeza no gutwikira porogaramu kandi bigabanya kugabanuka.

2.2 Kugenzura imiterere

HPMC igira ingaruka zikomeye kuri rheologiya yimyenda. Ikomeza ubwiza bukwiye bwo gutwikira mugihe cyo kubika kandi ikabuza gutwikira cyangwa gutuza. Mugihe cyo gusaba, HPMC itanga imiterere ikwiye kugirango ifashe irangi gukwirakwiza neza hejuru yubuso no gukora igifuniko cyiza. Byongeye kandi, uburyo bwogosha bwogosha burashobora kugabanya ibimenyetso bya brush cyangwa ibimenyetso byerekana mugihe cyo gusaba kandi bikazamura ubwiza bwimiterere ya firime yanyuma. 

2.3 Umukozi ukora firime

Imiterere ya firime ya HPMC ifasha kunoza imiterere nimbaraga za firime. Mugihe cyo kumisha, firime yakozwe na HPMC ifite ubukana nubworoherane, ishobora kongera imbaraga zo guhangana no kwambara, cyane cyane mubikorwa bimwe na bimwe bikenerwa cyane mu nganda, nk'amato, imodoka, n'ibindi, HPMC The imiterere-ya firime irashobora kunoza neza kuramba.

2.4

Nka stabilisateur, HPMC irashobora gukumira imvura yimvura, ibyuzuzo nibindi bice bikomeye muburyo bwo gutwikira, bityo bikazamura ububiko bwimyenda. Ibi birakenewe cyane cyane kumazi ashingiye kumazi. HPMC irashobora kubuza gusibanganya cyangwa guhuriza hamwe impuzu mugihe cyo kubika no kwemeza ubuziranenge bwibicuruzwa mugihe kirekire cyo kubika.

3. Gukoresha HPMC muburyo butandukanye

3.1

Amazi ashingiye ku mazi yitabiriwe cyane mu myaka yashize bitewe n’ibidukikije byangiza ibidukikije ndetse n’imyuka mibi ihindagurika (VOC). HPMC ikoreshwa cyane mumazi ashingiye kumazi. Nkibyimbye kandi bigahinduka, HPMC irashobora kunoza neza ububiko bwimikorere nubushobozi bwamazi ashingiye kumazi. Itanga uburyo bwiza bwo kugenzura ahantu hake cyangwa hejuru yubushyuhe, bigatuma irangi ryoroha iyo ryatewe, ryogejwe cyangwa ryizungurutse.

3.2 Irangi rya Latex

Irangi rya Latex nimwe mubikoreshwa cyane mubwubatsi muri iki gihe. HPMC ikoreshwa nkibikoresho byo kugenzura imvugo no kubyibuha mu gusiga irangi rya latex, bishobora guhindura ububobere bwirangi rya latex, bikongerera ikwirakwizwa, kandi bikabuza firime irangi kugabanuka. Byongeye kandi, HPMC igira ingaruka nziza zo gukwirakwiza irangi rya latex kandi ikabuza ibice bigize irangi gutura cyangwa gutondeka mugihe cyo kubika.

3.3 Irangi rishingiye ku mavuta

Nubwo ikoreshwa ry’amavuta ashingiye ku mavuta ryagabanutse muri iki gihe hamwe n’ibisabwa kurushaho kurengera ibidukikije, biracyakoreshwa cyane mu nganda zimwe na zimwe z’inganda, nk'icyuma gikingira ibyuma. HPMC ikora nk'umukozi uhagarika kandi agenzura rheologiya mu mavuta ashingiye ku mavuta kugirango yirinde pigment kandi ifashe igifuniko kugira urwego rwiza no gufatana mugihe cyo kubisaba.

4. Uburyo bwo gukoresha na dosiye ya HPMC

Ingano ya HPMC ikoreshwa mubitambaro isanzwe igenwa nubwoko bwo gutwikira hamwe nibisabwa bikenewe. Muri rusange, umubare wiyongereye wa HPMC usanzwe ugenzurwa hagati ya 0.1% na 0.5% byimbaraga zose zifatika. Uburyo bwo kongeramo ahanini ni ifu yumye yongeweho cyangwa igisubizo cyateguwe mbere hanyuma kongerwamo. Ingaruka zo guhindagurika no guhindagurika kwa HPMC ziterwa nubushyuhe, ubwiza bwamazi hamwe nubushyuhe. Kubwibyo, uburyo bwo gukoresha bugomba guhinduka ukurikije uko ibintu bimeze.

Hydroxypropyl methylcellulose (HPMC) ikoreshwa nkibyimbye, bigenzura rheologiya, umukozi ukora firime na stabilisateur mu mwenda w’inganda no gusiga amarangi, bitezimbere cyane imikorere yubwubatsi, ububiko bwububiko hamwe na firime yanyuma ya coating. ubuziranenge. Hamwe nogutezimbere ibidukikije byangiza ibidukikije hamwe n’isoko ryiyongera ku isoko ry’imyenda ikora neza, HPMC izakomeza kugira uruhare runini mu gutwikira inganda. Binyuze mu gukoresha mu buryo bushyize mu gaciro HPMC, imiterere yumubiri nu miti yimyenda irashobora kunozwa neza, kandi ingaruka zirambye hamwe nudushusho twa coating zirashobora kwiyongera.
