Hydroxypropyl methyl selulose ni iki?

Hydroxypropyl methyl selulose (HPMC), bizwi kandi nka hydroxypropyl methylcellulose, selulose hydroxypropyl methyl ether, selile, 2-hydroxypropylmethyl ether, PROPYLENE GLYCOL IZINDI METHYLCELLULOSE, CAS No 9004-65-3, ikozwe muri selulose yuzuye ipamba na etherification idasanzwe. HPMC irashobora kugabanywa mubyiciro byinyubako, urwego rwibiryo hamwe nu rwego rwa farumasi ukurikije imikoreshereze yabyo. Ikoreshwa cyane mubwubatsi, ibiryo, ubuvuzi no kwisiga, imiti ya buri munsi nizindi nganda.

Ni ubuhe buryo HPMC ikoresha?

Inganda zubaka

1. Masonry mortar
Gushimangira kwizirika hejuru yububiko bushobora kongera amazi, bityo bikazamura imbaraga za minisiteri, kandi bigatera amavuta na plastike kugirango bifashe kubaka. Ubwubatsi bworoshye butwara igihe kandi butezimbere ibiciro.
2. Ibicuruzwa bya gypsumu
Irashobora kongera igihe cyakazi cya minisiteri kandi ikabyara imbaraga zo gukanika mugihe cyo gukomera. Ubuso bwiza bwo hejuru buba bugizwe no kugenzura imiterere ya minisiteri.
3. Gukuramo irangi ryamazi no gukuraho amarangi
Irashobora kuramba igihe cyokwirinda imvura igwa, kandi ifite ubwuzuzanye buhebuje hamwe n’ibinyabuzima bihamye. Igipimo cyacyo cyo gusesa kirihuta kandi ntabwo byoroshye guhuriza hamwe, bifasha koroshya inzira yo kuvanga. Kora ibintu byiza biranga ibintu, harimo spatter nkeya hamwe no kuringaniza neza, urebe neza neza kurangiza neza, kandi wirinde gusiga irangi. Kongera ububobere bwo kuvanaho amarangi ashingiye kumazi hamwe no kuvanaho amarangi kama, kugirango kuvanaho amarangi bitazasohoka hejuru yakazi.
4. Ceramic tile yometseho
Ibikoresho byumye byumye byoroshye kuvanga kandi ntibiguteranya, bizigama igihe cyakazi kuko bikoreshwa vuba kandi neza, kunoza imikorere no kugabanya ibiciro. Kunoza imikorere ya tiling kandi utange neza cyane mugihe cyo gukonjesha.
5. Kuringaniza ibikoresho byo hasi
Itanga ubwiza kandi irashobora gukoreshwa nkinyongera yo gutuza kugirango ifashe kunoza imikorere ya etage. Kugenzura gufata amazi birashobora kugabanya cyane gucamo no kugabanuka.
6. Gukora ibisate byakozwe
Yongera uburyo bwo gutunganya ibicuruzwa biva hanze, bifite imbaraga zo guhuza hamwe no gusiga amavuta, kandi bitezimbere imbaraga zitose hamwe no gufatira kumpapuro zasohotse.
7. Isahani ihuriweho
Hydroxypropyl methyl selulose ifite amazi meza cyane, irashobora kongera igihe cyo gukonja, kandi amavuta menshi atuma ikoreshwa neza. Itezimbere neza ubuziranenge bwubuso, itanga neza ndetse nuburyo, kandi ituma ubuso buhuza neza.
8. Gypsumu ishingiye kuri sima
Ifite amazi menshi, yongerera igihe cyo gukora cya minisiteri, kandi irashobora no kugenzura iyinjira ryumwuka, bityo igakuraho uduce duto duto twa coater kandi igakora ubuso bunoze.

2. Ibicuruzwa bikonje bikonje: byongewe kumitobe yimbuto hamwe na barafu kugirango uburyohe burusheho kuba bwiza.
3. Isosi: ikoreshwa nka emulion stabilisateur cyangwa umubyimba wa sosi na paste yinyanya.
4. Nyuma yo gutwikira no gusya hamwe na methyl selulose cyangwa hydroxypropyl methyl selulose yumuti wamazi, funga hejuru yubura.
5. Gufata ibinini: Nkibikoresho bifata ibinini na granules, bifite "gusenyuka icyarimwe" (gusenyuka byihuse, gusenyuka no gutatana mugihe ufata).

2. Gusubiza inyuma: garama 2-3 kumunsi, 1-2G buri gihe, muminsi 4-5.
3. Umuti w'amaso: Kubera ko umuvuduko wa osmotic wa methyl selulose wamazi yo mumazi ameze nkaya marira, ntabwo arakaza amaso. Yongewe mumiti y'amaso nk'amavuta yo guhuza amaso.
4. Jelly: Ikoreshwa nkibikoresho fatizo bya jelly nkimiti yo hanze cyangwa amavuta.
5. Gutera inda: ikoreshwa nkibikoresho binini kandi bigumana amazi.

Izindi nganda

HPMC ikoreshwa kandi cyane mubikorwa bya sintetike, peteroli, ubukorikori, gukora impapuro, uruhu, wino ishingiye kumazi, itabi nizindi nganda. Ikoreshwa nkibyimbye, ikwirakwiza, ihuza, emulifier na stabilisateur mu nganda z’imyenda.

Nigute ushobora kumenya neza ubwiza bwa hydroxypropyl methyl selulose (HPMC)?

1. Nyamara, ibicuruzwa byiza biri hafi kugurwa.
2. Ubwiza: HPMC ifite meshes 80 na mes 100 100 muri rusange, naho meshes 120 ni nkeya. HPMCs nyinshi zifite meshes 80. Mubisanzwe nukuvuga, offside nziza nibyiza.
3. Itumanaho ryoroheje: shyira hydroxypropyl methyl selulose (HPMC) mumazi kugirango akore colloid ibonerana, hanyuma urebe itumanaho ryayo. Nini cyane itumanaho ryumucyo, nibyiza, byerekana ko harimo ibintu bitangirika.
4. Uburemere bwihariye: Uburemere bukomeye bwihariye, nibyiza. Umubare urakomeye, muri rusange kuko ibiri muri hydroxypropyl ni byinshi. Niba ibirimo hydroxypropyl ari byinshi, kubika amazi nibyiza.
Hydroxypropyl methyl selulose ihamye kuri acide na base, kandi igisubizo cyayo cyamazi kirahagaze neza murwego rwa pH = 2 ~ 12. Turi ababikora babigize umwuga. Niba ukeneye iki gicuruzwa, urashobora kutwandikira. Ibyo aribyo byose mugusangira HPMC muriki kibazo. Nizere ko ishobora kugufasha kumva HPMC.
