Ngwa nke Hydroxypropyl Methylcellulose na Gypsum

Hydroxypropyl Methylcellulose (HPMC)bụ ihe mgbakwunye a na-ejikarị eme ihe n'ụlọ, karịsịa na ngwaahịa gypsum. HPMC nwere ezigbo njide mmiri, ịgbara mmiri, mmanu na nrapado, na-eme ka ọ bụrụ ihe dị mkpa na ngwaahịa gypsum.

1. Ọrụ HPMC na gypsum

Ịkwalite njide mmiri

HPMC nwere ezigbo mmịnye mmiri na njigide mmiri. N'oge a na-eji ngwaahịa gypsum eme ihe, ịgbakwunye HPMC kwesịrị ekwesị nwere ike igbu oge n'iyi mmiri, meziwanye ọrụ nke gypsum slurry, na-edebe ya mmiri ruo ogologo oge n'oge a na-ewu ụlọ, ma zere mgbawa nke mmiri na-ebu ngwa ngwa kpatara.

Ịkwalite adhesion na mgbochi sagging Njirimara

HPMC na-enye gypsum slurry ezigbo adhesion, na-enye ya ohere ịrapagidesi ike na mgbidi ma ọ bụ ihe ndị ọzọ. Maka ihe gypsum nke arụrụ n'elu kwụ ọtọ, mmetụta na-agbapụta nke HPMC nwere ike ibelata ịla n'iyi ma hụ na ịdị n'otu na ịdị mma nke ihe owuwu.

Melite arụmọrụ ihe owuwu

HPMC na-eme ka gypsum slurry dị mfe itinye na ịgbasa, na-eme ka arụ ọrụ ụlọ dị mma ma na-ebelata ihe mkpofu. Tụkwasị na nke ahụ, ọ pụkwara ibelata esemokwu n'oge a na-ewu ụlọ, na-eme ka ọ dịkwuo mfe ma dị nro maka ndị na-arụ ọrụ ụlọ.

Melite nguzogide mgbape

N'oge usoro coagulation nke ngwaahịa gypsum, ikupu mmiri na-enweghị isi nwere ike ime ka mgbawa elu. HPMC na-eme ka gypsum hydration dịkwuo mma site na njigide mmiri ya dị mma, si otú a na-ebelata nhazi nke cracks na imeziwanye ogo ngwaahịa emechara.

Mmetụta na oge coagulation

HPMC nwere ike ịgbatị oge arụ ọrụ nke gypsum slurry n'ụzọ kwesịrị ekwesị, na-enye ndị ọrụ ihe owuwu ohere inwe oge zuru ezu iji dozie na mezie ihe, ma zere ọdịda ihe owuwu n'ihi coagulation nke gypsum ngwa ngwa.

2. Ngwa nke HPMC na ngwaahịa gypsum dị iche iche

Gypsum plasta

Na gypsum plasta ihe, isi ọrụ nke HPMC bụ imeziwanye njide mmiri na imeziwanye arụmọrụ ihe owuwu, ka gypsum wee nwee ike ịkwado mgbidi ahụ nke ọma, belata mgbawa, ma melite ogo ihe owuwu.

Gypsum putty

HPMC nwere ike melite mmanu na ire ụtọ nke putty, ebe ọ na-eme ka adhesion dịkwuo mma, na-eme ka ọ dịkwuo mma maka ịchọ mma.

gypsum osisi

N'imepụta bọọdụ gypsum, a na-ejikarị HPMC chịkwaa ọnụego hydration, gbochie bọọdụ ịsa ngwa ngwa, melite ogo ngwaahịa emechara, ma kwalite nguzogide mgbawa ya.

Gypsum na-edozi onwe ya

HPMC nwere ike na-arụ ọrụ nke ọma na gypsum na-edozi onwe ya, na-enye ya mmiri na nkwụsi ike ka mma, na-ezere nkewa na sedimentation, na imeziwanye arụmọrụ ụlọ.

3. Otu esi eji HPMC

Enwere ụzọ ndị a isi tinye HPMC na ngwaahịa gypsum:
Ngwakọta akọrọ ozugbo: Gwakọta HPMC ozugbo na ihe akọrọ dị ka gypsum ntụ ntụ, tinye mmiri ma kpalie ọbụna mgbe a na-ewu ya. Usoro a dabara adaba maka ngwaahịa gypsum agwakọtara, dị ka gypsum putty na plasta.

Tinye mgbe tupu mgbasa: igbari HPMC na mmiri n'ime a colloidal ngwọta mbụ, na mgbe ahụ tinye ya na gypsum slurry maka mma mgbasa na mgbasa. Ọ dabara maka ngwaahịa nwere ụfọdụ usoro pụrụ iche chọrọ.

4. Nhọrọ na usoro nchịkwa nke HPMC

Họrọ viscosity kwesịrị ekwesị

HPMC nwere ụdị viscosity dị iche iche, enwere ike ịhọrọ viscosity kwesịrị ekwesị dịka mkpa dị iche iche nke ngwaahịa gypsum siri dị. Dịka ọmụmaatụ, HPMC nwere viscosity dị elu dabara adaba maka ịba ụba na mgbochi sagging, ebe HPMC dị ala na-adaba adaba maka ihe gypsum nwere mmiri dị elu.

Iji ezi uche na-achịkwa ọnụọgụ mgbakwunye

Ọnụ ego nke HPMC agbakwunyere na-adịkarị ala, n'ozuzu n'etiti 0.1%-0.5%. Mgbakwunye dị ukwuu nwere ike imetụta nhazi oge na ike ikpeazụ nke gypsum, ya mere a ga-edozi ya nke ọma dịka njirimara ngwaahịa na ihe owuwu ihe a chọrọ.

Hydroxypropyl methylcellulosena-arụ ọrụ dị mkpa na ihe ndị dabeere na gypsum. Ọ bụghị naanị na ọ na-eme ka njigide mmiri na ịrụ ọrụ ụlọ, kamakwa ọ na-eme ka adhesion na nkwụsị mgbawa, na-eme ka ngwaahịa gypsum kwụsie ike ma dịgidere. Nhọrọ ezi uche dị na ya na ojiji nke HPMC nwere ike imeziwanye ogo ngwaahịa gypsum ma gboo mkpa dị iche iche nke ihe owuwu.
