Hydroxypropyl methyl cellulose ni iki?

Hydroxypropyl methyl cellulose (HPMC), izwi kandi nka hydroxypropyl methylcellulose, cellulose hydroxypropyl methyl ether, cellulose, 2-hydroxypropylmethyl ether, PROPYLENE GLYCOL ETHER YA METHYLCELLULOSE, CAS No. 9004-65-3, ikorwa muri cellulose y'ipamba nziza cyane hakoreshejwe etherification yihariye mu bihe bya alkaline. HPMC ishobora kugabanywamo urwego rw'inyubako, urwego rw'ibiribwa n'urwego rw'imiti hakurikijwe ikoreshwa ryayo. Ikoreshwa cyane mu bwubatsi, ibiribwa, ubuvuzi n'amavuta yo kwisiga, imiti ya buri munsi n'izindi nganda.

Ni izihe nyungu za HPMC?

Inganda z'ubwubatsi

1. Sima yo mu mabuye
Gukomeza uburyo amazi afatwa n'ubuso bw'amabuye bishobora kongera ubushobozi bwo kubika amazi, bityo bikanoza imbaraga za sima, kandi bikanoza ubushyuhe n'ubukonje kugira ngo bifashe mu mikorere y'ubwubatsi. Kubaka byoroshye bizigama igihe kandi bikongera imikorere myiza y'amafaranga.
2. Ibicuruzwa bya Gypsum
Bishobora kongera igihe cyo gukora cya mortiweri no gutanga imbaraga nyinshi mu gihe cyo gukonja. Ubuso bwiza bukorwa no kugenzura imiterere ya mortiweri.
3. Irangi riva mu mazi n'iry'irangi rikuraho
Ishobora kongera igihe cyo kumara igihe kirekire ibuza imvura kugwa, kandi ifite ubushobozi bwo guhuza neza n'uburyo ikora neza. Ishobora gushonga vuba kandi ntiyoroshye kuyivanga, ibi bikaba ingirakamaro mu koroshya inzira yo kuvanga. Itanga imiterere myiza y'amazi, harimo no kugabanya amazi no kugabanya ingano yayo, ikora neza ku buso bwayo, kandi ikarinda ko irangi rigwa. Yongera ubukana bw'imashini ikuraho irangi ishingiye ku mazi n'imashini ikuraho irangi ry'umwimerere, kugira ngo imashini ikuraho irangi idasohoka mu buso bw'ibikoresho.
4. Kole y'amatafari ya ceramic
Ibikoresho byumye byoroshye kubivanga kandi ntibiteranya, bikagabanya igihe cyo gukora kuko bikoreshwa vuba kandi neza, bikongera ubushobozi bwo gutunganya no kugabanya ikiguzi. Kunoza imikorere y'amatafari no gutanga uburyo bwiza bwo gufatana binyuze mu kongera igihe cyo gukonjesha.
5. Ibikoresho byo kwiyongerera hasi
Itanga ubushyuhe kandi ishobora gukoreshwa nk'inyongeramusaruro irinda guhagarara kugira ngo ifashe kunoza imikorere y'ubutaka. Kugenzura uburyo amazi abikwamo bishobora kugabanya cyane imiturire no gucikagurika.
6. Gukora ibyuma bya sima byakozwe
Yongera ubushobozi bwo gutunganya ibicuruzwa bivanwaho, ifite imbaraga nyinshi zo gufatanya n'amavuta, kandi ikongera imbaraga zo gutose no gufatana kw'impapuro zivanwaho.
7. Ifu y'isahani yo gushyiramo ibintu
Selulosi ya Hydroxypropyl methyl ifite ubushobozi bwo kubika amazi neza, ishobora kongera igihe cyo gukonjesha, kandi ubushyuhe bwayo bwinshi butuma ikoreshwa rirushaho kuba ryiza. Inoza neza ubwiza bw'ubuso, itanga uburyohe bwiza kandi bungana, kandi ituma ubuso bufatanye burushaho gukomera.
8. Gypsum ishingiye kuri sima
Ifite amazi menshi, yongera igihe cyo gukora cya mortiweri, kandi ishobora no kugenzura uburyo umwuka winjira, bityo ikavanaho uduce duto tw’igitambaro kandi igakora ubuso bworoshye.

Inganda z'ibiribwa

1. Imbuto z'imiti zibikwa mu macupa: kugira ngo hirindwe ko umweru ugabanuka no kwangirika bitewe no kubora kwa glycosides z'imiti mu gihe cyo kubika, kugira ngo bigire ingaruka nziza zo kubika.
2. Ibikomoka ku mbuto zikonje: byongewe mu mutobe w'imbuto no mu rubura kugira ngo birusheho kunogerwa.
3. Isosi: ikoreshwa nk'umuti utuma isosi n'inyanya bikomera cyangwa ikanabyimbisha.
4. Gusiga no gusiga amazi akonje: bikoreshwa mu kubika amafi akonje kugira ngo hirindwe ko ibara ryayo rihinduka kandi hirindwe ko ubuziranenge bwayo bwangirika. Nyuma yo gusiga no gusiga ukoresheje methyl cellulose cyangwa hydroxypropyl methyl cellulose amazi, shyira muri frique ku rubura.
5. Kole ikoreshwa mu gushushanya ibinini: Nk'uko kole ikoreshwa mu gushushanya ibinini n'udusimba, igira "gusenyuka icyarimwe" (gusenyuka vuba, gusenyuka no gukwirakwira mu gihe uyifata).

Inganda z'imiti

1. Gufunga: Umuti ukoreshwa mu gufunga ukorwa mu buryo bw'umuti ukomoka ku bimera cyangwa umuti w'amazi wo gutanga ibinini, cyane cyane mu gufunga uduce twateguwe.
2. Ingaruka mbi: garama 2-3 ku munsi, 1-2G ku gihe, mu minsi 4-5.
3. Umuti w'amaso: Kubera ko umuvuduko wa osmotic w'umuti w'amazi wa methyl cellulose ari umwe n'uw'amarira, ntutera umujinya mwinshi ku maso. Ushyirwa mu muti w'amaso nk'amavuta yo kwisiga kugira ngo ukore ku mboni y'amaso.
4. Jeli: Ikoreshwa nk'ibikoresho by'ibanze bya jeli nk'umuti wo hanze cyangwa amavuta yo kwisiga.
5. Itera inda: ikoreshwa nk'ikintu gikomeza ubushyuhe n'amazi.

Inganda zo kwisiga

1. Shampoo: Yongera ubukana n'ubudahangarwa bw'umushongi wa shampoo, imashini yo kumesa n'isabune.
2. Umuti w'amenyo: wongera ubushyuhe bw'amenyo.

Inganda zikora amatanura

1. Ibikoresho bya elegitoroniki: nk'ubutare bukora imashini ikora amashanyarazi ya ceramic compactor na ferrite bauxite magnet, ishobora gukoreshwa hamwe na 1.2-propanediol.
2. Umuti wa Glaze: ukoreshwa nk'umuti wa Glaze ukozwe mu bumba kandi uhujwe n'irangi rya enamel, bishobora kunoza ubufatanye n'uburyo bwo gutunganya ibintu.
3. Urusenda rurekura: Rushobora kongerwa ku rusenda rurekura cyangwa ibikoresho by'itanura kugira ngo rurusheho kuba rwiza kandi amazi akomeze kubikwa neza.

Izindi nganda

HPMC ikoreshwa cyane mu nganda zikora ubutare bwa sintetike, peteroli, ibumba, gukora impapuro, uruhu, wino ishingiye ku mazi, itabi n'izindi nganda. Ikoreshwa mu gukurura, gukwirakwiza, gufunga, gusya no gushimangira mu nganda z'imyenda.

Ni gute wamenya neza ubwiza bwa hydroxypropyl methyl cellulose (HPMC)?

1. Ubuziranenge bw'ibipimo: nubwo budashobora kumenya neza niba HPMC yoroshye kuyikoresha, kandi niba ibikoresho byo kuyungurura byongewemo mu musaruro, ubwiza bwayo buzahinduka. Ariko, ibicuruzwa byiza bigiye kugurwa.
2. Ubutonyanga: HPMC ifite meshes 80 na meshes 100 muri rusange, naho meshes 120 ni nkeya. HPMC nyinshi zifite meshes 80. Muri rusange, ubutonyanga bwa offside ni bwiza kurushaho.
3. Uburyo bwo kohereza urumuri: shyiramo hydroxypropyl methyl cellulose (HPMC) mu mazi kugira ngo habeho koloyide ibonerana, hanyuma urebe uko urumuri rwayo rugenda. Uko urumuri rugenda rwinshi, ni ko birushaho kuba byiza, bigaragaza ko hari ibintu bidashonga cyane muri yo.
4. Uburemere bwihariye: Uko uburemere bw'uburemere bwihariye burushaho kuba bwiza, niko burushaho kuba bwiza. Igipimo ni kinini, muri rusange kubera ko ingano ya hydroxypropyl ari nyinshi. Iyo ingano ya hydroxypropyl ari nyinshi, amazi agumana neza.
Selulosi ya Hydroxypropyl methyl irahamye ku bimera bya aside na base, kandi umuti wayo w'amazi urahamye cyane mu rugero rwa pH = 2 ~ 12. Turi uruganda rw'inzobere. Niba ukeneye iki gicuruzwa, ushobora kutwandikira. Ibyo byose ni ukugira ngo HPMC isangirwe muri iki kinyamakuru. Ndizera ko bizagufasha gusobanukirwa HPMC.
