4. N'ịkwanye gypsum, ijikọ gypsum, na ijikọ gypsum
Site na mmepe ngwa ngwa nke ụlọ ọrụ owuwu ụlọ, ọchịchọ ndị mmadụ maka ihe owuwu ọhụrụ na-amụba kwa ụbọchị. N'ihi mmụba nke mmata ndị mmadụ banyere nchekwa gburugburu ebe obibi na mmụba na-aga n'ihu na arụmọrụ owuwu, ngwaahịa gypsum simenti etolitela ngwa ngwa. Ugbu a, ngwaahịa gypsum kachasị ewu ewu bụ plastering gypsum, gypsum bonding, gypsum inlaid, na taịlị gluu.
Gypsum plastering bụ ihe e ji eme plastering dị elu maka mgbidi na ụlọ dị n'ime. Elu mgbidi e ji ya mee dị mma ma dịkwa ire ụtọ. Ihe mgbakwunye ọhụrụ nke gypsum bụ ihe na-arapara arapara nke e ji gypsum mee dị ka ihe ndabere na ihe mgbakwunye dị iche iche. Ọ dabara adaba maka ijikọ n'etiti ihe dị iche iche nke mgbidi ụlọ na-adịghị mma. Ọ naghị egbu egbu, ọ naghị esi isi, ike mbụ na ntọala ngwa ngwa, njikọ siri ike na njirimara ndị ọzọ, ọ bụ ihe nkwado maka bọọdụ ụlọ na owuwu blọk; ihe na-eme ka gypsum caulking bụ ihe na-eme ka oghere dị n'etiti bọọdụ gypsum na ihe na-eme ka mgbidi na mgbawa dị.
Ngwaahịa gypsum ndị a nwere usoro ọrụ dị iche iche. Na mgbakwunye na ọrụ nke gypsum na ihe ndị metụtara ya, isi okwu bụ na ihe mgbakwunye cellulose ether agbakwunyere na-arụ ọrụ dị mkpa. Ebe ọ bụ na gypsum kewara n'ime gypsum anhydrous na hemihydrate gypsum, gypsum dị iche iche nwere mmetụta dị iche iche na arụmọrụ nke ngwaahịa ahụ, yabụ ọkpụrụkpụ, idobe mmiri na nkwụsịtụ na-ekpebi ịdị mma nke ihe owuwu gypsum. Nsogbu a na-ahụkarị nke ihe ndị a bụ oghere na mgbawa, enweghịkwa ike iru ike mbụ. Iji dozie nsogbu a, ọ bụ ịhọrọ ụdị cellulose na usoro ojiji nke retarder. N'akụkụ a, a na-ahọrọkarị methyl ma ọ bụ hydroxypropyl methyl 30000. -60000cps, ego mgbakwunye bụ 1.5%–2%. N'ime ha, cellulose na-elekwasị anya na idobe mmiri na igbochi mmanụ.
Agbanyeghị, ọ gaghị ekwe omume ịdabere na cellulose ether dị ka ihe na-egbochi ihe, ọ dịkwa mkpa ịgbakwunye ihe na-egbochi ihe na-egbochi ihe na-agwakọta ma jiri ya na-enweghị mmetụta nke ike mbụ.
Njide mmiri na-ezo aka n'otú mmiri ga-esi efufu n'ụzọ ebumpụta ụwa na-enweghị mmiri mpụga. Ọ bụrụ na mgbidi ahụ kpọrọ nkụ nke ukwuu, mmiri na-amịkọrọ mmiri na ikuku sitere n'okike n'elu ala ga-eme ka ihe ahụ ghara ịpụ apụ ngwa ngwa, oghere na mgbawa ga-emekwa.
A na-agwakọta ụzọ a na ntụ akọrọ. Ọ bụrụ na ị kwadebe ihe ngwọta, biko lee usoro nkwadebe nke ihe ngwọta ahụ.
5. Ngwa agha mkpuchi okpomọkụ
Mkpụchi mkpuchi bụ ụdị ihe mkpuchi mgbidi dị n'ime ime na mpaghara ugwu. Ọ bụ ihe mgbidi nke e ji ihe mkpuchi, ihe mkpuchi na ihe njikọ mepụta. N'ime ihe a, cellulose na-arụ ọrụ dị mkpa n'ịjikọta na ịbawanye ike. Na-ahọrọkarị methyl cellulose nwere oke viscosity (ihe dị ka 10000eps), usoro ọgwụgwọ ahụ na-adịkarị n'etiti 2‰-3‰), ụzọ eji eme ya bụ ịgwakọta ntụ ntụ kpọrọ nkụ.
6. Onye nnọchi anya interface
Họrọ HPNC 20000cps maka ihe nnọchi anya interface, họrọ 60000cps ma ọ bụ karịa maka ihe njikọta taịlị, ma lekwasị anya na ihe siri ike dị na ihe nnọchi anya interface, nke nwere ike ime ka ike nrụgide na ike mgbochi akụ́ dịkwuo mma.
