Intangiriro ku rwego rw'inganda rwa HPMC

1. HPMC yo mu rwego rw'inganda ni iki?

Icyiciro cy'ingandaHPMC (Hydroxypropyl Methylcellulose)ni eteri ikomoka kuri cellulose itari ionic, akenshi iba mu buryo bw'ifu y'umweru cyangwa umuhondo muto. Ikorwa mu migozi y'ipamba karemano binyuze mu gutunganya alkali no mu buryo butandukanye bw'ibinyabutabire (nk'ubushyuhe), kandi ifite ubushobozi bwo guhuza neza ibinyabutabire n'ubudahangarwa bw'ibinyabutabire. Bitewe n'imiterere yayo yihariye y'umubiri n'imiti, HPMC ikoreshwa cyane mu nganda nyinshi nko mu bwubatsi, mu gusiga irangi, mu byuma bya ceramic, no mu buhinzi.

2. Imikorere y'ingenzi ya HPMC yo mu rwego rw'inganda

Ubunini

HPMC ifite ubushobozi bwo gukurura neza kandi ishobora kongera ubukana bw'amazi, bityo ikarushaho kunoza imiterere, ubushyuhe n'ubushobozi bwo koza ibikomoka ku bicuruzwa.

Kubika Amazi

Mu bikorwa nka morti na putty, HPMC ishobora kunoza cyane uburyo amazi abikwa mu bikoresho, ikarinda gutakaza amazi vuba, yongere igihe cyo gukora, kandi ikanoza ubucucike n'uburyo bifatanye n'ibicuruzwa byarangiye.

Gukora Filime

HPMC ishobora gukora agapira gakomeye kandi gafite isura ku buso, bigatuma ibicuruzwa birushaho kuba byiza mu kurinda no kubyaza umusaruro.

Gutatana no gukwirakwiza ingano y'ibinyabutabire

HPMC ifite ubushobozi bwo gukwirakwira neza mu mazi kandi ishobora gukoreshwa nk'ikintu gitera imbaraga mu gutuma sisitemu ikomeza guhindagurika no kunoza uburyo ikoreshwa mu gupima no guhagarara neza.

Gushyira ubushyuhe mu gipimo cy'ubushyuhe

Umuti w'amazi wa HPMC uzakora gel iyo ishyushye ku bushyuhe runaka. Iyi miterere ya gel ishobora guhindurwa ifite agaciro gakomeye mu bintu bimwe na bimwe byihariye.

3. Ahantu hakuru hakoreshwa HPMC yo mu rwego rw'inganda

Inganda z'ubwubatsi

Urusenda rwumye (nk'urusenda rw'amatafari, urusenda rwa plaster, urusenda rwo kwiyongerera): HPMC ishobora kunoza uburyo amazi abikwa, afatwa neza n'imikorere y'ubwubatsi bwa rusenda.

Ifu ya puti: Kunoza imiterere y'inyubako, gukumira gucika no gushoka, no kunoza ubwiza bw'ubuso bw'igicuruzwa kirangiye.

Sisitemu yo gukingira inyuma (EIFS): Yongera uburyo bwo gufatana no koroha kwa sima no gukomeza igihe kirekire.

Inganda zikora amarangi

HPMC ikoreshwa nk'umuti ugabanya ubushyuhe, utuma ibintu bikomera kandi bigafata neza firime kugira ngo inoze imikorere yo kurwanya kugwa, itume ibintu bihagarara neza kandi ihuze neza n'uburyo irangi ringana.

Inganda za ceramic

Mu gukora intanga za keramike, HPMC igira uruhare mu kubika amazi, gushyira amavuta mu mubiri, gushushanya, nibindi, bigafasha kunoza ubucucike n’ubudahangarwa bw’umusaruro.

Ibikoresho bya shimi bya buri munsi

Kongera HPMC mu byuma bisukura no mu byuma bisukura bishobora kongera imiterere y'ibicuruzwa, bigatuma ifuro rirushaho kuba ryiza kandi riramba, kandi bigatuma formula ihora ihamye.

Gucukura amavuta

Nk'inyongeramusaruro ku mazi acukurwa, HPMC ishobora guhindura imiterere y'amazi acukurwa, ikarinda gusenyuka kw'urukuta rw'iriba, kandi ikanoza imikorere myiza yo gucukura.

4. Uburyo bwo gukoresha HPMC yo mu rwego rw'inganda

Ubusanzwe, HPMC igomba gushirwa mu mazi akonje kugira ngo ikore umuti umwe kugira ngo ikore neza. Intambwe zisanzwe zo kuyikoresha ni izi zikurikira:

Suka HPMC buhoro buhoro kandi neza mu mazi akonje yavunganyuwe kugira ngo wirinde kwivanga kw'amazi.

Komeza kuvanga kugeza igihe bitangiriye gukwirakwira.

Hagarara igihe runaka (muri rusange amasaha arenga 2) kugira ngo unyweze neza kandi ushongeshe selulose.

Niba ari ngombwa, kangura witonze kugeza igihe habonetse umuti umwe ubonerana cyangwa ubonerana.

Mu bikorwa nyabyo by’inganda, ingano ya HPMC yongeweho rimwe na rimwe irahindurwa uko bikenewe, muri rusange ikagenzurwa hagati ya 0.1% na 2.0%, kandi igipimo cyihariye giterwa na sisitemu ya formula n’ingaruka zifuzwa.

5. Igenzura ry'ubuziranenge n'icyitegererezo cyo guhitamo

HPMC yo mu rwego rw'inganda ifite imiterere itandukanye ya viscosity (nk'urugero 400 mPa.s, 15000 mPa.s, nibindi) n'igipimo cyo gusimbuza (urugero urugero rwo gusimbuza hydroxypropyl na methyl) hakurikijwe ibisabwa bitandukanye byo gukoreshwa. Guhitamo icyitegererezo gikwiye bigira ingaruka zikomeye ku mikorere y'umusaruro. Ibintu bisanzwe byo gupima birimo:

Ubushyuhe (2% by'umuti ku bushyuhe bw'icyumba)

Ubushyuhe burimo

Ibirimo ivu

Ibikubiye muri methoxy na hydroxypropyl

Agaciro ka pH (1% y'umuti w'amazi)

HPMC yo mu rwego rwo hejuru mu nganda igomba kugira imiterere y’ivu rike, ikwirakwira neza, ubushyuhe buhamye, kandi ishonga vuba.

6. Kubika no gupakira

HPMC igomba kubikwa ahantu hakonje, humutse, hafite umwuka mwiza, hirindwa ubushyuhe bwinshi, ubushuhe n'izuba kugira ngo hirindwe ko ubushuhe bukwirakwira, guhumeka cyangwa impinduka mu mikorere. Akenshi ipfunyikwa mu mifuka myinshi y'impapuro zivanze iriho imifuka ya polyethylene. Ibipimo bisanzwe byo gupfunyika ni 25 kg/umufuka, kandi bishobora no guhindurwa hakurikijwe ibyo umukiriya akeneye.

HPMC yo mu rwego rw'ingandaIfite uruhare rudasimburwa mu nganda nyinshi kubera imiterere yayo myiza y’umubiri n’imiti. Bitewe n’ubwiyongere bw’ibikoresho by’ubwubatsi by’icyatsi kibisi, irangi ritangiza ibidukikije n’ibikoresho bivanze neza, icyifuzo cya HPMC nziza nacyo kiriyongera. Mu gihe kizaza, hamwe no kunoza ibikorwa byo gukora no kwagura imirima ikoreshwa, HPMC yo mu rwego rw’inganda izagaragaza amahirwe menshi yo gutera imbere.
