Lekwasị anya na cellulose ethers

Enwere ike iji HPMC na ngwa owuwu dị iche iche?

HPMC (hydroxypropyl methylcellulose) bụ kemịkalụ kemịkalụ nke a na-ejikarị eme ihe n'ihe owuwu na mpaghara ụlọ ọrụ ndị ọzọ. Ọ bụ ether cellulose na-abụghị ionic nke sitere na cellulose eke emezigharịrị na kemịkal. HPMC nwere dị iche iche ọrụ dị ka ndim, mmiri njide, film e guzobere, mmanu, na adhesion, na-enye ya sara mbara ngwa ike na-ewu ụlọ ọrụ.

1. Key arụmọrụ nke HPMC na-ewu ngwa

(1) Mmetụta dị arọ

Mgbe HPMC gbazere na mmiri, ọ nwere ike ịbawanye viscosity nke mmiri mmiri. Mmetụta a na-eme ka ọkpụkpụ dị oke mkpa na ihe ụlọ. Dịka ọmụmaatụ, na ciment mortar, HPMC nwere ike ime ka viscosity nke ngwa agha dịkwuo mma, mee ka ọ dị mfe ịrụ ọrụ, ma mee ka ihe owuwu ahụ dị nro.

 

(2) Njide mmiri

HPMC nwere ezigbo njide mmiri, nke na-ebelata ikuku mmiri na ọnọdụ akọrọ. Nke a dị mkpa karịsịa na ihe ndị sitere na ciment iji gbochie ngwa agha ma ọ bụ kọmpat ịsachapụ ma ọ bụ na-efunahụ ike n'ihi oke mmiri na-efunahụ ngwa ngwa tupu ịtọọ ya. Tụkwasị na nke ahụ, njide mmiri nwere ike imeziwanye oge mmeghe nke adhesives na putty powder, na-enye ndị ọrụ ihe owuwu oge iji gbanwee.

 

(3) Anti-sag ihe onwunwe

N'ime ihe owuwu kwụ ọtọ (dị ka plasta mgbidi ma ọ bụ tiling), HPMC nwere ike igbochi ihe ahụ nke ọma ịda n'ihi ike ndọda. Ọ na-enyere ngwa ngwa ma ọ bụ nrapado aka ịnọgide na-enwe ezigbo nrapado ma na-eme ka owuwu dị mma.

 

(4) Ngwongwo ime ihe nkiri mara mma

HPMC na-emepụta ihe nkiri otu mgbe akpọnwụchara, ihe na-emepụta ihe nkiri nke dị oke egwu na mkpuchi mmiri na ala na-edozi onwe ya. Ihe mkpuchi a na-emepụta ihe nkiri nwere ike ime ka mmiri na-eguzogide mmiri na ihu igwe nke ihe.

 

(5) Lubrication na njikọta mmetụta

HPMC nwere ike melite mmanu nke ihe owuwu ụlọ, belata esemokwu n'oge a na-ewu ụlọ, ma mee ka ihe ahụ gbasaa nke ọma n'elu ala. Tụkwasị na nke a, HPMC nwere ike ịkwalite njirimara njikọ ma melite ike njikọ na ụfọdụ nrapado.

2. Ngwa nke HPMC na kpọmkwem ihe owuwu ubi

(1) Ngwa ngwa sitere na ciment

N'iji plasta, ngwa agha masonry, na ngwa agha na-ebuli onwe ya, HPMC nwere ike imezi njide mmiri na mmiri nke ngwa agha ahụ, si otú a na-emeziwanye arụmọrụ ihe owuwu na ogo ịkpụzi ikpeazụ. Na mgbakwunye, ihe mgbochi sag nke HPMC na-eme ka a mata na ngwa agha ahụ agaghị agbada ngwa ngwa mgbe etinyere ya na mgbidi kwụ ọtọ.

 

(2) Ceramic tile nrapado

Isi ihe achọrọ maka nrapado taịlị bụ ike njikọta na ịdị mfe nke owuwu. HPMC na tile adhesive nwere ike ọ bụghị naanị melite adhesion nke colloid, kamakwa ịgbatị oge mmeghe, na-ekwe ka ndị ọrụ na-ewu ụlọ nwee ogologo oge nhazigharị, si otú ahụ na-emeziwanye arụmọrụ ụlọ.

(3) Putty ntụ ntụ

HPMC na-enye ntụ ntụ putty ezigbo njigide mmiri na mmiri. N'oge a na-arụ ọrụ putty, njide mmiri na-egbochi oyi akwa isi ka ọ ghara ịmịnye mmiri ngwa ngwa, na-eme ka putty na-akpọnwụ nke ọma, ma na-ebelata ihe ize ndụ nke ịgbawa na ịdaba.

 

(4) mkpuchi mkpuchi mmiri

Ihe na-emepụta ihe nkiri nke HPMC dị nnọọ mma maka mkpuchi mmiri. Ọ nwere ike inyere mkpuchi ahụ aka ịmepụta akwa akwa mmiri na-adịghị mma na nke edo n'elu mkpụrụ ahụ iji welie ikike mgbochi mmiri nke ihe owuwu ụlọ.

 

(5) Ngwaahịa dabere na gypsum

Na gypsum na-eme ka ihe ndị na-emepụta ihe na ihe nkedo, HPMC na-enye ezigbo njide mmiri, na-egbochi gypsum ka ọ ghara ịla n'iyi n'ihi oke mmiri mmiri. N'otu oge ahụ, ya ndim mmetụta nwere ike melite mfe nke ngwa.

 

3. Uru na njedebe nke HPMC

 

Uru:

Ngwa zuru oke: Kwesịrị ekwesị maka ihe dị iche iche, dị ka ciment, gypsum, lime, wdg.

Nchedo gburugburu ebe obibi: Dị ka ihe nrụpụta cellulose, HPMC adịghị mma, anaghị egbu egbu ma na-egbo mkpa nchekwa gburugburu ebe obibi.

Ntughari: Na-enye ihe dị iche iche dị ka njide mmiri, njupụta, na nhazi ihe nkiri, ma nwee ike ime mgbanwe maka mkpa nke ihe owuwu dị iche iche.

 

oke:

Ọnụ: Ọnụ ego HPMC dị ntakịrị elu ma e jiri ya tụnyere ụfọdụ ihe ọdịnala, nke nwere ike ịbawanye ọnụ ahịa mmepụta ihe ụlọ.

Oke Nguzogide Alkaline: Enwere ike imebi arụmọrụ HPMC na mpaghara ụfọdụ oke alkaline, na-achọ nnwale na mgbanwe maka mpaghara akọwapụtara.

 

4. Ike nke HPMC na-ewu n'ọdịnihu

Ka ụlọ ọrụ na-ewu ihe na-achọsi ike maka ịrụ ọrụ dị elu, ihe ndị na-emetụta gburugburu ebe obibi na-etolite, mpaghara ngwa nke HPMC na-agbasawanye. Dịka ọmụmaatụ, n'ime ụlọ akwụkwọ ndụ akwụkwọ ndụ na ụlọ ndị na-adịghị ike, HPMC nwere ike iji dị ka ihe mgbakwunye isi iji mepụta ike na-arụ ọrụ nke ọma na gburugburu ebe obibi. N'otu oge ahụ, na ọganihu nkà na ụzụ, ọrụ na nkwụsi ike nke HPMC ga-akawanye mma.

 

Dị ka ihe mgbakwunye multifunctional,HPMCnwere ọrụ na-enweghị ike dochie anya ihe owuwu ihe. Site na ngwa ngwa ciment gaa na nrapado tile, site na putty ntụ ntụ na mkpuchi mmiri, enwere ike iji ya na ihe fọrọ nke nta ka ọ bụrụ ihe owuwu ụlọ. Site na njirimara ya magburu onwe ya, HPMC na-enyere aka melite arụmọrụ ihe owuwu na ịdịte aka nke ihe ụlọ ma bụrụ akụkụ dị mkpa nke mmepe ụlọ ọrụ n'ọdịnihu.
