Ọrụ nke hydroxypropyl methylcellulose (HPMC) na ihe gypsum dị ezigbo mkpa. A na-eji ihe gypsum eme ihe n'ọtụtụ ebe na-ewu, ịchọ mma na ubi mmepụta ihe ndị ọzọ. Dị ka ihe mgbakwunye multifunctional, HPMC na-ejikarị na ihe gypsum. Ọrụ ya bụ isi gụnyere imeziwanye arụmọrụ ọrụ nke gypsum slurry, ịkwalite ike njikọ, na-achịkwa oge nhazi na imeziwanye ịdịte aka nke ihe.
Isi ọrụ HPMC na gypsum
1. Melite arụmọrụ ọrụ
HPMC nwere ike imeziwanye arụmọrụ arụ ọrụ nke gypsum slurry, na-eme ka ọ dịkwuo mma na ịrụ ọrụ. Nke a bụ n'ihi na HPMC nwere mmetụta dị mma nke na-eme ka ọ dịkwuo mma ma nwee ike ịbawanye viscosity nke slurry, si otú ahụ na-egbochi slurry si deaminating, imi na ndị ọzọ phenomena n'oge a na-ewu usoro. Tụkwasị na nke ahụ, HPMC nwekwara ike imeziwanye ọrụ njigide mmiri nke gypsum slurry, nke mere na ọ gaghị akpọnwụ n'ihi mmiri na-ekpo ọkụ ngwa ngwa n'oge usoro ihe owuwu.
2. Kwalite ike njikọ
HPMC nwere ike ịkwalite ike njikọ dị n'etiti gypsum na mkpụrụ. Nke a bụ n'ihi na HPMC nwere ike ịmepụta usoro netwọk dị mma na gypsum slurry, nke na-eme ka nchikota nke gypsum slurry dịkwuo elu, si otú ahụ na-emeziwanye ikike njikọ ya na mkpụrụ. Tụkwasị na nke ahụ, HPMC nwekwara ogo nke wettability, nke nwere ike ime ka mpaghara kọntaktị dị n'etiti gypsum slurry na elu nke mkpụrụ ahụ, na-eme ka njikọ ahụ dịkwuo mma.
3. Jikwaa oge coagulation
HPMC nwere ike ijikwa oge nhazi nke gypsum slurry nke ọma. Mgbakwunye nke HPMC nwere ike belata ọsọ ntọala nke gypsum slurry, na-enye ndị na-arụ ọrụ ụlọ oge zuru ezu iji rụọ ọrụ na ịhazigharị, ma zere ntụpọ ihe owuwu nke ntọala ngwa ngwa kpatara. Nke a dị mkpa karịsịa maka ihe owuwu buru ibu na ngwaahịa plasta dị mgbagwoju anya.
4. Meziwanye ike ihe onwunwe
HPMC nwekwara ike imeziwanye ịdịte aka nke ihe gypsum. Mgbakwunye nke HPMC nwere ike ịkwalite nguzogide mgbape nke ihe gypsum ma gbochie ihicha na mgbawa nke mgbanwe okpomọkụ na mgbanwe iru mmiri kpatara. Na mgbakwunye, HPMC nwekwara ụfọdụ ihe mgbochi mmiri, nke nwere ike belata mbuze nke mmiri na ihe gypsum ma gbasaa ndụ ọrụ ha.
Ụkpụrụ ngwa nke HPMC na gypsum
1. Ụkpụrụ na-agba agba
Ọdịdị molekụla nke HPMC nwere ọnụ ọgụgụ buru ibu nke hydroxyl na methyl. Otu ndị a na-arụ ọrụ nwere ike ịmepụta njikọ hydrogen na ụmụ irighiri mmiri, si otú ahụ na-amụba viscosity nke slurry. Mmetụta siri ike nke HPMC nwere ike ọ bụghị naanị melite mmiri na ịrụ ọrụ nke gypsum slurry, kamakwa melite nkwụsi ike nke slurry ma gbochie delamination na mmiri ozuzo.
2. Ụkpụrụ njide mmiri
HPMC nwere ezigbo njide mmiri ma nwee ike ịmepụta ihe nkiri ejigide mmiri na gypsum slurry iji belata evaporation mmiri. Mmetụta njide mmiri nke HPMC nwere ike igbochi slurry site na ịgbawa ma na-ebelata n'oge usoro ihicha, meziwanye àgwà na iji mmetụta nke ihe gypsum.
3. Ụkpụrụ njikọ
HPMC nwere ike ịmepụta nhazi netwọk dị mma na gypsum slurry iji mee ka njikọ nke slurry dịkwuo elu. N'otu oge ahụ, mmiri mmiri nke HPMC nwere ike ime ka mpaghara kọntaktị dị n'etiti gypsum slurry na elu nke mkpụrụ ahụ, si otú ahụ na-emeziwanye ike njikọ.
4. Ụkpụrụ nke ịchịkwa oge coagulation
HPMC nwere ike igbu oge nhazi ọsọ nke gypsum slurry, tumadi site n'ịgbanwe ọsọ mmeghachi omume hydration na slurry. Mgbakwunye nke HPMC nwere ike belata mmeghachi omume hydration nke calcium sulfate na gypsum slurry, na-enye slurry ogologo oge ọrụ yana ịrụ ọrụ ka mma.
5. Ụkpụrụ nke nkwalite ịdịte aka
Mmetụta ume ike nke HPMC nwere ike imeziwanye mgbape mgbape nke ihe gypsum ma gbochie nkụja akọrọ na mgbawa nke mgbanwe okpomọkụ na mgbanwe iru mmiri kpatara. Tụkwasị na nke ahụ, arụmọrụ mmiri nke HPMC nwere ike ibelata nsị nke ihe gypsum site na mmiri ma gbasaa ndụ ha.
Ngwa nke HPMC na ihe gypsum bara ezigbo uru. Site n'ịkwalite arụmọrụ nke gypsum slurry, ịkwalite ike nkekọ, ịchịkwa oge nhazi na imeziwanye ịdịte aka nke ihe ahụ, HPMC nwere ike imeziwanye àgwà na iji mmetụta nke ihe gypsum. Ya mere, HPMC abụrụla ihe dị mkpa na ihe dị mkpa nke ihe gypsum na ihe owuwu ọgbara ọhụrụ na ọrụ ịchọ mma.
