Lekwasị anya na cellulose ethers

Kedu ihe bụ isi ojiji nke hydroxypropyl methylcellulose na ụlọ ọrụ ihe owuwu?

Hydroxypropyl methylcellulose (HPMC) bụ polymer multifunctional nke a na-ejikarị eme ihe na ụlọ ọrụ ihe owuwu n'ihi njirimara na ọrụ ya pụrụ iche. Ngwa ahụ sitere na cellulose ma gbanwee site na ịgbakwunye hydroxypropyl na methyl otu. Ya mere HPMC na-egosiputa ihe dị iche iche na-eme ka ọ dị mma maka ngwa dị iche iche na mpaghara ihe owuwu.

Njide mmiri na ihe na-eme ka mmiri sie ike:

Otu n'ime isi ọrụ HPMC na-ewu bụ ikike ya ịrụ ọrụ dịka onye na-ejigide mmiri. Nke a dị oke mkpa maka ihe ndị sitere na ciment, ebe ọ bụ na idobe mmiri kwesịrị ekwesị dị mkpa maka hydration kwesịrị ekwesị na ọgwụgwọ. HPMC na-enyere aka igbochi evaporation nke mmiri ngwa ngwa, hụ na ngwakọta ciment na-anọgide na-arụ ọrụ ruo ogologo oge.

HPMC nwekwara ike iji dị ka thickener na-amụba viscosity nke ihe ụlọ. Nke a bara uru karịsịa na ngwa ndị dị ka adhesives tile na ogige nkwonkwo, nke chọrọ nkwụsi ike siri ike maka ngwa ngwa na njikọ dị mma.

Nrụ ọrụ emelitere:

HPMC na-enyere aka melite arụ ọrụ nke ngwa agha na ihe ngwakọta. Site n'ịchịkwa ọdịnaya mmiri na ịkwalite akụrụngwa rheological, enwere ike ijikwa ihe ndị a ma tinye ya ngwa ngwa. Nke a dị mkpa karịsịa n'oge usoro ihe owuwu dị ka plasta, nsụgharị na ọrụ masonry.

Mee ka nrapado nke tile dịkwuo mma:

Na adhesives tile, HPMC na-eme ka adhesion dịkwuo mma site n'inye viscosity na-agbanwe agbanwe. Nke a na-eme ka taịlị ndị ahụ na-akwadosi ike na mkpụrụ osisi ahụ, na-egbochi nsogbu ndị dị ka mwepu ma ọ bụ bee ka oge na-aga. Njirimara njide mmiri a na-achịkwa nke HPMC na-arụkwa ọrụ dị mkpa n'inweta nrapado kacha mma.

Nguzogide mgbawa na ịdịte aka emelitere:

Ịtinye HPMC na nhazi nke simenti nwere ike inye aka belata mgbawa. Nke a bara uru karịsịa maka ngwa ndị dị ka kọmpat, ebe ibelata mgbawa dị oke mkpa maka iguzosi ike n'ezi ihe na ịdịte aka nke ngwaahịa emechara. HPMC na-enyere aka idobe iguzosi ike n'ezi ihe nke ihe ahụ ka ọ na-agwọ ma na-eto.

Ngwakọta na-ebuli onwe ya:

A na-ejikarị HPMC eme ihe na ogige na-ebuli onwe ya iji mepụta ebe dị larịị, dị larịị na ngwa ala. Njirimara njide mmiri nke HPMC na-arụ ọrụ dị mkpa n'ịchịkwa oge ihicha nke ogige ndị a, na-enye ohere ịkwado onwe ya nke ọma na-enweghị ntọala akaghi aka.

Ngwaahịa sitere na gypsum:

HPMC bụ ihe mgbakwunye dị mkpa na ngwaahịa gypsum dị ka gypsum. Ọ na-eme ka arụ ọrụ nke stucco dịkwuo mma, na-eme ka adhesion n'elu elu, ma na-enyere aka nweta ihe na-agbanwe agbanwe na ọbụna imecha. Ikike njide mmiri nke HPMC bara uru karịsịa na ngwa gypsum.

Sistemụ Mkpuchi Mpụga na Mmecha (EIFS):

EIFS bụ usoro mkpuchi na-ewu ewu n'ime ụlọ, na-enye mkpuchi ọkụ na ihe ịchọ mma. A na-eji HPMC eme ihe na usoro EIFS iji melite njirimara nrapado nke primer ma hụ na njikọ siri ike n'etiti bọọdụ mkpuchi na mkpụrụ.

Ngwa mkpuchi mkpuchi:

HPMC bụ akụkụ dị mkpa nke ngwa mkpuchi ọkụ. A na-eji ngwa agha ndị a na-ewu ụlọ na-arụ ọrụ ike iji kwalite ihe mkpuchi ọkụ. HPMC na-enyere aka n'ịnọgide na-agbanwe agbanwe achọrọ ka a na-etinye ngwa agha ndị a nke ọma n'ụdị dị iche iche.

Ntọhapụ nke mgbakwunye na-achịkwa:

Enwere ike iji HPMC kpuchie ma chịkwaa ntọhapụ nke ihe mgbakwunye dị iche iche n'ime ihe owuwu ụlọ. Nke a dị mkpa karịsịa mgbe a na-achọ ka a na-ahapụ ihe ndị dị ka biocides ma ọ bụ corrosion inhibitors iji nweta ọrụ ogologo oge na nchebe nke ihe ụlọ.

Nkwụsi ike emulsion:

Na-ewu ngwa na-eji emulsions, dị ka asphalt emulsions, HPMC na-eme dị ka a stabilizer. Ọ na-enyere aka igbochi mmiri na bitumen nkewa, na-eme ka nkwụsi ike na ịdị n'otu nke emulsion.

Ndakọrịta na mgbakwunye ndị ọzọ:

HPMC dakọtara na ọtụtụ ihe mgbakwunye ihe owuwu ndị ọzọ. Ọdịiche a na-enye ndị na-emepụta ihe aka ịhazi arụmọrụ nke ihe owuwu ụlọ ka ọ bụrụ ihe achọrọ, ma ọ bụ na-edozi oge ịtọlite ​​​​oge, meziwanye nrapado ma ọ bụ ịkwalite arụmọrụ nke ihe niile.

Omume ụlọ akwụkwọ ndụ akwụkwọ ndụ:

A na-enwekarị mmasị na HPMC na omume ụlọ akwụkwọ ndụ akwụkwọ ndụ n'ihi na ọ na-enwe mmetụta biodegradability na mmetụta gburugburu ebe obibi dị ala. Ojiji ya na-agbaso ụkpụrụ iwu ụlọ na-adigide, na-eme ka ọ bụrụ nhọrọ mara mma maka ọrụ enyi na gburugburu ebe obibi.

Ngwakọta jikọrọ ọnụ na mkpuchi texture:

Na nkwonkwo adhesives na texture coatings, HPMC mma n'ozuzu arụmọrụ site na-enye mkpa rheology, mfe ngwa na sanding Njirimara. Ọ na-ekerekwa òkè n'ịkwalite njikọ nke ihe ndị a n'elu.

Caulks na sealants:

Na nhazi nke caulks na sealants, HPMC na-enyere aka nweta nkwekọ na extrudability chọrọ. Ọ na-enyere aka melite arụmọrụ zuru oke nke ngwaahịa ndị a site n'ịhụ na adhesion na mgbanwe kwesịrị ekwesị na-edobe n'oge.

Belata mbelata na ngwa kwụ ọtọ:

Maka ngwa kwụ ọtọ dị ka mkpuchi na agba, HPMC na-enyere aka igbochi sag site n'inye ihe ndị thixotropic. Nke a dị oke mkpa iji dowe ọkpụrụkpụ otu n'elu kwụ ọtọ na-enweghị ihe ọ bụla na-ada ma ọ bụ na-asọpụta.

N'ikpeazụ, hydroxypropyl methylcellulose na-arụ ọrụ dị mkpa na ụlọ ọrụ mmepụta ihe, na-enye ọtụtụ uru dị iche iche na njide mmiri, ịrụ ọrụ, adhesion na ogologo oge. Ngwa ngwa ya dị iche iche na-eme ka ọ bụrụ ihe mgbakwunye dị mkpa iji nweta ihe ndị a chọrọ nke ngwaahịa ikpeazụ. Ka omume ihe owuwu na-aga n'ihu na-etolite, HPMC nwere ike ịdịwanye mkpa n'ịkwalite arụmọrụ na nkwado nke ihe ụlọ.
