Ngwa ngwa agwakọta akọrọ nke dabere na gypsum bụ ụdị ihe mgbidi ọhụrụ a na-ejikarị arụ ọrụ. Isi ihe ya bụ gypsum, nke ihe ndị ọzọ na-ejuputa na ihe mgbakwunye kemịkalụ gbakwunyere. Iji meziwanye arụmọrụ nke ngwa agha agwakọta akọrọ nke gypsum, ọ na-adịkarị mkpa ịgbakwunye mgbakwunye pụrụ iche-hydroxypropyl methylcellulose (HPMC). HPMC nwere ọtụtụ ọrụ dị ka ịgbakọ, njide mmiri, na mmanu mmanu, ma na-arụ ọrụ dị mkpa na ngwa ngwa agwakọta agwakọta nke gypsum.
1. Ọrụ nke HPMC na gypsum sitere na ngwa agha akọrọ akọrọ
Kwalite njide mmiri
Ngwakọta akọrọ agwakọta nke gypsum kwesịrị ịnọgide na-enwe ụfọdụ mmiri mmiri ruo ogologo oge n'oge a na-ewu ya iji hụ na ike ya na nchikota ya mgbe ọ gbasịrị. HPMC nwere ikike njigide mmiri dị mma, nke nwere ike belata mfu mmiri n'oge a na-ewu ụlọ ma hụ na arụ ọrụ nke ngwa agha gypsum na-arụ ọrụ tupu ọ sie ike. Karịsịa na akọrọ na ebe a na-ewu ụlọ na-ekpo ọkụ, njide mmiri dị mkpa karịsịa, nke na-enyere aka ịgbatị oge ọrụ ihe owuwu ma melite ogo ihe owuwu.
Mmetụta siri ike
Dị ka a thickener, HPMC nwere ike melite agbanwe agbanwe nke gypsum dabeere akọrọ-ngwakọta ngwa agha na-amụba mfe nke owuwu. Mmetụta dị nro nwere ike ime ka ngwa agha ahụ dị nro n'oge a na-arụ ọrụ, na-adịchaghị mfe ịkwaga, ma melite nkwụsi ike na ịrụ ọrụ nke ọma. Mmetụta na-akpụ akpụ ahụ nwekwara ike inye aka melite akụrụngwa mgbochi mgbochi ngwa ngwa ma zere akwa ngwa ngwa na-ekwekọghị ekwekọ nke sagging kpatara.
Melite arụmọrụ mmanu mmanu
N'oge a na-ewu ụlọ, mmetụta mmanu mmanu nke HPMC nwere ike ime ka ngwa ngwa gbasaa ngwa ngwa, na-eme ka ngwa agha gypsum dịkwuo mfe ịgbasa n'elu mgbidi, si otú ahụ na-eme ka ọsọ na ịrụ ọrụ nke ọma dịkwuo mma. Njirimara mmanu mmanu nke HPMC nwekwara ike ibelata esemokwu n'etiti ngwaọrụ ihe owuwu na ngwa agha, na-eme ka ịdị mma nke ihe owuwu dịkwuo mma.
Melite njirimara njikọ
Ike njiko nke ngwa agha agwakọta akọrọ nke dabere na gypsum na-emetụta àgwà ihe owuwu ahụ ozugbo. HPMC nwere ike ịkwalite nrachi nke ngwa agha na mkpụrụ, melite ike nke ngwa agha, mee ka ọ sie ike mgbe akpọnwụchara, ma belata ohere nke ịgbawa. Njirimara a dị oke mkpa iji hụ na ịdị mma na ịdịte aka nke ihe owuwu.
2. Uru nke HPMC
Nchedo gburugburu ebe obibi
HPMC bụ ihe na-adịghị egbu egbu na nke na-adịghị emerụ ahụ nke na-emezu ụkpụrụ nchedo gburugburu ebe obibi. Dị ka ngwaahịa ether cellulose, iji HPMC agaghị emepụta gas ma ọ bụ ihe mkpofu na-emerụ ahụ, ọ gaghịkwa ebu gburugburu ebe obibi. Ọ bụ ihe mgbakwunye ụlọ na-acha akwụkwọ ndụ akwụkwọ ndụ na gburugburu ebe obibi.
Nkwụsi ike nke kemịkal
HPMC na-egosi nkwụsi ike kemịkalụ dị mma na ngwa agha agwakọta agwakọta gypsum, agaghị emeghachi omume ọjọọ na ihe ndị ọzọ kemịkalụ, yana arụmọrụ ya ka kwụsiri ike n'okpuru ọnọdụ gburugburu ebe dị iche iche. Ma na elu okpomọkụ, ala okpomọkụ, iru mmiri ma ọ bụ akọrọ gburugburu ebe obibi, arụmọrụ nke HPMC nwere ike na-ekwe nkwa na ọ gaghị ada n'ihi mgbanwe gburugburu ebe obibi.
Ịdị ogologo
HPMC nwere ike imeziwanye ịdịte aka nke ngwa agha agwakọtara akọrọ nke dabere na gypsum ma belata mgbawa na peeling n'elu ngwa ngwa. Ịdị ogologo ya na-eme ka nhazi nke gypsum gypsum dịkwuo mma, na-ebelata ọnụ ahịa nke nrụzi mgbe e mesịrị, ma na-enye nkwa maka iji ụlọ eme ihe ogologo oge.
Ike mgbanwe
HPMC nwere ike ime mgbanwe na ụdị ihe dị iche iche, gụnyere kọmpụta, masonry, aerated concrete, wdg, ma gosipụta ezigbo ndakọrịta. Nke a na-enye ohere ka a na-eji gypsum na-ekpo ọkụ na-ekpo ọkụ na-ekpo ọkụ na-eme ihe n'ọtụtụ ebe na ihe ụlọ dị iche iche, na-enye ihe ngwọta na-agbanwe agbanwe maka mkpa ihe owuwu dị iche iche.
3. Mkpa iji HPMC na ngwa agha agwakọta akọrọ dabere na gypsum
Melite arụmọrụ ihe owuwu
Ihe owuwu nke oge a nwere ihe dị elu ma dị elu chọrọ maka ịrụ ọrụ nke ọma, na iji HPMC nwere ike imeziwanye arụmọrụ nke ngwa agha akọrọ akọrọ nke dabeere na gypsum, mee ka owuwu ya dị ngwa, ma gboo mkpa nke ịrụ ngwa ngwa. Nke a dị mkpa karịsịa maka nnukwu ihe owuwu ihe owuwu, nke nwere ike belata oge ihe owuwu ma chekwaa ụgwọ ọrụ.
Melite ogo ihe owuwu
Ogo ihe owuwu na-emetụta nchekwa na ịdịte aka nke ụlọ ahụ ozugbo. Ihe mgbakwunye nkeHPMCnwere ike ime ka njigide mmiri dị mma, nkwụchi na nkwụsị nke mgbawa nke ngwa agha ahụ, na-eme ka oyi akwa akwa mgbe e wuchara ya dị nro na nke siri ike, belata mkpa maka ịrụ ọrụ na nhazi, ma hụ na nkwụsi ike nke ụlọ ahụ dum.
Kwado na gburugburu ihe owuwu dị mgbagwoju anya
Okpomọkụ, iru mmiri na ihe ndị ọzọ dị na ebe a na-ewu ụlọ na-enwe mmetụta dị ukwuu na arụmọrụ nke ngwa agha ahụ, na mgbakwunye nke HPMC nwere ike inyere gypsum na-ekpo ọkụ na-ekpo ọkụ na-ekpo ọkụ na-arụ ọrụ nke ọma na-arụ ọrụ nke ọma na gburugburu ebe siri ike. Dịka ọmụmaatụ, n'ebe okpomọkụ dị elu ma ọ bụ ebe iru mmiri dị ala, HPMC nwere ike ijikwa mmiri nke ngwa agha ahụ nke ọma, gbochie mgbawa ma ọ bụ mbelata nke ihicha ngwa ngwa kpatara, ma welie mgbanwe nke ngwa agha ahụ.
Belata ụgwọ ihe owuwu ụlọ
Ọ bụ ezie na ịtinye HPMC ga-abawanye ọnụ ahịa ihe, ọ na-eme ka arụ ọrụ nke ngwa agha dịkwuo mma ma na-ebelata ohere nke ịrụ ọrụ n'oge a na-ewu ụlọ na ọnụ ahịa nrụzi na-akpata site na mgbawa, peeling na nsogbu ndị ọzọ. N'ime ogologo oge, iji HPMC nwere uru na njikwa ọnụ ahịa, karịsịa na ọrụ ndị nwere oke mma chọrọ, nke nwere ike imeziwanye arụmọrụ ọnụ ahịa n'ozuzu ya.
HPMC bụ ihe mgbakwunye gypsum sitere na ọkpọkọ-agwakọta nke nwere ike imezi njide mmiri nke ọma, mmetụta na-ebuwanye ibu, mmanu na ike njikọta nke ngwa agha ahụ, na-eme ka ngwa agha ahụ dịkwuo mma ma kwụsie ike n'oge a na-ewu ya. Ọ bụghị naanị na ọ na-eme ka arụmọrụ na ịdị mma na-arụ ọrụ dịkwuo mma, kamakwa ọ na-enyere ndị na-ewu ụlọ aka ime mgbanwe na gburugburu ebe obibi dị mgbagwoju anya ma na-eme ka ọ dị ogologo oge nke ụlọ ahụ.
