Hydroxypropyl methylcellulose (HPMC) bụ polymer vasatail eji n'ọtụtụ ụlọ ọrụ, gụnyere ihe owuwu.N'ihe gbasara plasta gypsum, HPMC nwere ọtụtụ ojiji ma na-arụ ọrụ dị mkpa n'ịkwalite arụmọrụ na ịdịmma nke plasta.
Mụta maka Hydroxypropyl Methylcellulose (HPMC):
1. Chemical Ọdịdị na Njirimara:
HPMC bụ polima nke na-agbaze mmiri na-amịpụta ọkara nke sitere na cellulose.
Ọ nwere ihe ndị pụrụ iche dị ka njide mmiri, ike ịgbasa na ike imepụta ihe nkiri.
Usoro kemịkalụ nke HPMC gụnyere hydroxypropyl na methoxy dị iche iche, nke na-enye ihe ndị a kapịrị ọnụ nke polymer.
2. Usoro mmepụta:
Usoro mmepụta na-agụnye etherification nke cellulose, na-eme ka e nwee HPMC.
Enwere ike ịhazi ogo ngbanwe nke hydroxypropyl na otu methoxy iji metụta njirimara nke polymer.
Ngwa na plasta gypsum:
1. Njide mmiri:
HPMC na-arụ ọrụ dị ka onye na-ejigide mmiri na nhazi gypsum.
Ọ na-enyere aka ịchịkwa ọdịnaya mmiri, na-egbochi ihicha ngwa ngwa ma na-eme ka mmiri dị n'otu nke akụkụ gypsum.
2. Melite ikike ịrụ ọrụ:
Mgbakwunye nke HPMC na-eme ka plasta gypsum rụọ ọrụ.
Ọ na-enye ngwakọta nke plasta dị nro na nke na-eme ka ọ dị mfe ịgbasa n'elu.
3. Ọbara:
Dị ka ihe na-eme ka ọ dị arọ, HPMC na-enyere aka ịbawanye viscosity nke ngwakọta gypsum.
Nke a na-enyere aka na mma mmachi n'elu vetikal na-ebelata sagging n'oge ngwa.
4. Tọọ njikwa oge:
HPMC na-emetụta oge nhazi nke gypsum.
Usoro onunu kwesiri ekwesi na-enye ohere ka edozie oge iji zute ihe oru ngo a choro.
5. Melite nrapado:
Ihe na-emepụta ihe nkiri nke HPMC na-eme ka adhesion nke plasta gypsum dịkwuo mma n'ụdị dị iche iche.
Nke a na-eme ka plasta rụchaa ya dịkwuo ogologo ma na-adịte aka.
6. Nguzogide mgbawa:
HPMC na-enyere aka melite n'ozuzu ike na mgbanwe nke nkedo.
Polymer na-enyere aka belata ihe ize ndụ nke mgbawa, na-enye ihe na-edozi ahụ na nke mara mma.
7. Ndakọrịta na mgbakwunye ndị ọzọ:
HPMC nwere ndakọrịta dị mma na mgbakwunye ndị ọzọ a na-ejikarị na usoro gypsum.
Nke a na-enye ohere ịmepụta ngwakọta nke plasta ahaziri dabere na ihe achọrọ kpọmkwem.
Ụkpụrụ Ogo na ntuziaka:
1. Ụkpụrụ ụlọ ọrụ:
HPMC maka plasta na-agbaso ụkpụrụ ụlọ ọrụ na ụkpụrụ.
Usoro njikwa mma na-eme ka arụmọrụ na ntụkwasị obi na-agbanwe agbanwe.
2. Atụmatụ usoro onunu ogwu:
Ndị na-emepụta ihe na-enye ntụziaka usoro onunu ogwu dabere na ihe ndị a chọrọ maka nhazi gypsum.
Usoro ọgwụgwọ kwesịrị ekwesị dị oke mkpa iji nweta ihe ndị a chọrọ n'emebighị arụmọrụ.
Hydroxypropyl methylcellulose (HPMC) bụ isi ihe dị na nhazi gypsum, na-enyere aka melite njide mmiri ya, ịrụ ọrụ, nrapado na ọrụ zuru ezu.Ka ụlọ ọrụ ihe owuwu na-aga n'ihu na-etolite, ọrụ HPMC n'ịkwalite ogo na ịrụ ọrụ nke plasta gypsum ka dị mkpa.Site n'ịghọta kemịkalụ na ngwa nke HPMC, ndị ọrụ ụlọ ọrụ na-ewu ụlọ nwere ike ịme mkpebi mara mma iji nweta nsonaazụ kacha mma na ọrụ plasta ha.
