Hydroxypylthylthylthylcelllose (HPMC) bụ mmiri dị mkpa - solulose cellulose na ọtụtụ ngwa dị iche iche, karịsịa na ụlọ owuwu na ihe owuwu. Na ngwaahịa Gypsim, a na-ejikarị HPMC mee ihe dị ka nke na-eme nke ọma, mmiri na-agbasa, na-agbasasị na fim mbụ, nke budata arụmọrụ na iji mmetụta nke ngwaahịa Gypsum.
1. Kwalie ọrụ nke gypsum slurry
Gypsum slurry bụ ihe eji eme ihe n'ọtụtụ ebe, ọkachasị na mma na mma. Mgbe ojiji nke gypsum slurry, otu esi agba mbọ hụ na ndị ọrụ iwu nwere ike ịrụ ọrụ na imezi ụdị ihe ahụ bụ okwu dị mkpa. HPMC nwere ezigbo ihe dị mma ma nwee ike ịmepụta usoro victous dị na Gypsum iji zere ịdị gịrịgịrị ma ọ bụ na-ekwekọghị, si otú a na-eme ka ihe owuwu owuwu nke gypsum slurry.
Kpamkpam, Hpmc na-abawanye viscosity nke slurry iji mee ka ọ kwụsie ike, ndị ọrụ na-arụ ọrụ nwere ike ịnweta mkpuchi mkpuchi karịa mgbe itinye akwụkwọ. Karịsịa na ihe osise mgbidi na ọrụ mmezi, ọnya na-agbanwe na adhesion nke gypsum dị ezigbo mkpa. Ihe mgbakwunye HPMC nwere ike ime ka arụmọrụ arụ ọrụ ma zere ihe na-egbu egbu ma na-abanye.
2. Meziwanye njigide mmiri nke ngwaahịa Gypsim
Omume dị mkpa nke ngwaahịa Gypsum bụ njigide mmiri ya, nke na-emetụta ọsọ ọsọ ya na ike ikpeazụ. Dịka mmiri na-ejide onwe ya, HPMC nwere ike igbu oge na-egbu oge mmiri, si otú ahụ na-ejikwa usoro ciment nke gypsum ma zere nguzobe nke mmiri.
Dinggbakwunye HPMC na Gypsum akọrọ ntụ ntụ nke Gypsum, na-agbatị oge ọrụ ya, ma na-enyere Gypsum aka ogologo oge na owuwu. Njirimara a dị ezigbo mkpa mgbe ị na-arụ ọrụ buru ibu, nke nwere ike ịgba mbọ hụ na gypsum zuru oke na nke a na-ejikarị kpuchie ya.
3. Meziwanye ikike nke Gypsum
N'oge ojiji, gypsum na-abatakwa na isi ala, ma na-agba mbọ ezi njikọ bụ isi ihe dị mma nke ngwaahịa Gypsum. HPMC nwere ike iwelie ngwa na ike n'etiti gypsum na ihe isi. Ndị otu Hydroxypyl na Methyl na ihe owuwu ya nwere ike iso mkpụrụ osisi site na njikọta Hydrogen na Mgbasaanya nke anụ ahụ.
Karịsịa mgbe ị na-emeso mkpụrụ ndị dị mgbagwoju anya, dị ka taịl, iko, ọla, wdg, mgbakwunye nke HPMC nwere ike ịkwalite ndọtị nke gypsum ma na-egbochi ịwụda. Nke a dị oke mkpa iji mee ka ịhazi ụdị ihe na -ebelata.
4. Meziwanye nguzogide nke gypsum
N'oge usoro nke gypsum, ma ọ bụrụ na mmiri ahụ kpochapụ ngwa ngwa ma ọ bụ ebe mpụga gbanwere nke ukwuu, crack nwere ike ime. HPMC nwere ike inyere Goypsum aka ịnọgide na-enwe mmiri mmiri site na imezigharị Rhology na njigide mmiri nke gypsum slurry, na-ezere cracks nke oke ihicha ngwa ngwa. Ọrụ HPMC na Gypsum adịghị oke egbu egbu mmiri, kamakwa enwere ike ịkwalite ike nke ihe ahụ site na usoro polymer nke ya n'oge usoro gypsum, si otú a na-eme ka mmegide ndagide.
Karịsịa mgbe ị na-agbago nnukwu mpaghara ma ọ bụ mgbidi na-arụzigharị, HPMC nwere ike belata ihe omume nke cracks n'oge owuwu ma hụ na ngwaahịa gypsum dị larịị ma kwụsie ike.
5. Meziwanye ahịhịa na-enweghị uche nke gypsum
N'ime ụfọdụ ngwa Gypsim nke chọrọ elu dị elu, mmiri na ọkwa onwe ya na-eto eto. HPMC nwere ike imeziwanye gypsum, na-eme ka ọ dị nro na ụdị ọzọ n'oge usoro ngwa. Na mgbakwunye, HPMC nwekwara ike ịkwalite onwe ya nke gypsum slurry. Ọbụlagodi mgbe ị na-ewu nnukwu mpaghara, gypsum nwere ike itolite ala dị larịị na nke dị larịị, belata ego mmezi n'oge owuwu n'oge owuwu n'oge owuwu n'oge owuwu n'oge owuwu n'oge owuwu n'oge owuwu n'oge owuwu n'oge owuwu n'oge owuwu n'oge owuwu n'oge owuwu.
6. Meziwanye ihe owuwu nke Gypsum
Ihe mgbakwunye HPMC nwere ike imeziwanye arụmọrụ nke ngwaahịa Gypsum. Nke mbu, o nwere ike belata oru ike ndi oru ulo oru banyere onu ogugu ma belata nsogbu oru. Nke abuo, hpmc na-eme ka nkwụsi ike nke Gypsum na-agbanwe ngwa ngwa mgbanwe na-agbanwe ngwa ngwa mgbanwe ma ọ bụ mgbanwe iru mmiri, si otú a na-eme ka ọ dị mma ma rụọ ọrụ nke iwu.
N'ọnọdụ ụfọdụ ndị pụrụ iche, dị ka oke okpomọkụ ma ọ bụ gburugburu akọrọ rụọ, njigide mmiri nke HPMC dị ezigbo mkpa. Ọ nwere ike mee ka oge ọrụ nke gypsum mee ihe ma zere ihicha ma sie ike, si na -ebelata ihe dị iche iche na-arụ ọrụ.
87. Ọrụ gburugburu na nchekwa
HPMC bụ ihe polmer sitere na polmer nke na-eme gburugburu ebe obibi na nchekwa ma na-emezu ihe ndị na-enye akwụkwọ ndụ akwụkwọ ndụ. Iji HPMC usoro na usoro GPPSUm enweghị ike ime ka arụmọrụ, kamakwa na nchekwa gburugburu ebe obibi na ihe na-enweghị ihe ọ bụla maka akwụkwọ ndụ akwụkwọ ndụ na ihe nchekwa.
A na-eji HPMC mee ihe n'ọtụtụ usoro Gypsum. Ọrụ ya dị ka nke na-agbagharị, mmiri na-ejikọ, ndị na-agbasasị na fim bụ ihe dị mma ka mma ịrụ ọrụ owuwu ahụ, adhesion, na-emegide nguzo na gburugburu ebe obibi nke ngwaahịa ndị Gypsim. Na mmụba na-abawanye maka ihe ndị dị elu na ụlọ ọrụ owuwu, atụmanya nke HPMC na usoro Gypsum ga-abawanye.
