Hydroxypropyl methylcellulose (HPMC) bụ cellulose ether nke sitere na cellulose eke na-ejikarị eme ihe na ụlọ ọrụ ihe owuwu n'ihi ihe ndị pụrụ iche na ọdịdị ya. N'ime ihe cimentious, HPMC na-arụ ọrụ dị iche iche, gụnyere imeziwanye arụmọrụ, njigide mmiri, nrapanye, na ịdịte aka.
1. kwalite arụmọrụ:
Ịrụ ọrụ bụ akụkụ dị mkpa nke kọnkịta na ngwa agha, na-emetụta ntinye ha, ịkwado na imecha usoro. Ihe mgbakwunye HPMC na-arụ ọrụ dị mkpa n'ịkwalite usoro nhazi site na ibelata mmiri chọrọ ka ị na-edobe nkwekọ achọrọ. The elu mmiri njide ike nke HPMC gbatịrị workability maka mma ọnyịnye na finishing nke ihe na ngwa agha ngwakọta. Na mgbakwunye, HPMC gbanwetụrụ ihe cementitious na-egosipụta mma rheological Njirimara, na-eme ka mgbapụta dị mfe na ịwụsa ọrụ n'ime ọrụ owuwu.
2. Njide mmiri:
Njide mmiri dị oke mkpa iji hụ na hydration zuru oke nke ihe simenti, ọkachasị na ihu igwe na-ekpo ọkụ ma ọ bụ kpọrọ nkụ ebe mmiri na-efunahụ ngwa ngwa nwere ike ime. Ihe mgbakwunye HPMC na-arụ ọrụ dị ka ihe na-ejigide mmiri dị irè, na-egbochi ihicha kọmpụta na ngwa ngwa ngwa ngwa. HPMC na-ebelata evaporation mmiri site n'ịmepụta ihe nkiri dị mkpa gburugburu irighiri ciment, si otú a na-agbatị usoro hydration na ịkwalite mmepe ike kacha mma. Njirimara a bara uru karịsịa na gburugburu ebe okpomọkụ dị elu ma ọ bụ nke dị ala, ebe ịnọgide na-enwe oke iru mmiri nwere ike isi ike.
3. Kwalite adhesion:
Njikọ dị n'etiti ihe simenti na mkpụrụ osisi dị oke mkpa maka ịrụ ọrụ na ogologo oge nke ihe ụlọ dị ka ihe ntanye tile, plasta na plasta. Ihe mgbakwunye HPMC na-eme ka adhesion dịkwuo mma site n'ịkwalite ike njikọ dị n'etiti elu ihe na nrapado ma ọ bụ mkpuchi. Ihe na-emepụta ihe nkiri nke HPMC na-emepụta ihe mgbochi na-eme ka kọntaktị dị n'etiti nrapado na mkpụrụ, na-ebute ịrụ ọrụ njikọ dị elu. Na mgbakwunye, HPMC na-enyere aka ibelata ihe ndapụta nke mgbawa, si otú ahụ na-emeziwanye ịdịte aka nke elu ahụ jikọtara ọnụ.
4. Melite ogologo oge:
Ịdị ogologo oge bụ isi ihe a na-echebatara n'iwu ụlọ, ọkachasị n'ihe owuwu ekpughere n'ọnọdụ ọnọdụ gburugburu ebe obibi siri ike ma ọ bụ nrụgide igwe. Ihe mgbakwunye HPMC na-enyere aka melite ịdịte aka nke ihe cimentious site n'ịbawanye nguzogide ha n'ihe ndị dị ka okirikiri mmiri oyi, ọgụ kemịkalụ na abrasion. Site n'ịkwalite ịrụ ọrụ na ibelata ikike mmiri, HPMC na-enyere aka belata ntinye nke ihe ndị na-emerụ ahụ n'ime ihe na ngwa agha, si otú ahụ gbasaa ndụ ọrụ ha. Na mgbakwunye, ihe ndị HPMC agbanweela na-egosipụta ike mgbanwe na mkpakọ, si otú a na-emeziwanye arụmọrụ nhazi yana ịdịte aka.
5. Uru mmepe na-adigide:
Na mgbakwunye na uru ọrụ aka ha, ihe mgbakwunye HPMC na-eweta uru nkwado dị ukwuu na mpaghara ihe owuwu. Dị ka ihe na-emebi emebi na ihe mmeghari ohuru sitere na cellulose, HPMC na-enyere aka belata mmetụta gburugburu ebe obibi nke ihe owuwu ihe. Site n'ịkwalite njirimara nke ihe simenti, HPMC nwere ike iji ọdịnaya ciment dị ala na ngwakọta, si otú a na-ebelata ikuku carbon na-ejikọta na mmepụta ciment. Na mgbakwunye, HPMC wusiri ngwa agha na kọmpat na-enyere aka melite arụmọrụ ike nke ụlọ site na imeziwanye ihe mkpuchi ọkụ yana ibelata mkpa maka kpo oku na oyi.
6. Atụmanya:
Achọ maka ihe ụlọ na-adigide na omume na-aga n'ihu na-eto eto, na-ebute ihe ọhụrụ na mmepe nke mgbakwunye enyi na gburugburu ebe obibi dịka HPMC. Ọdịnihu nke HPMC na ụlọ ọrụ ihe owuwu na-egbuke egbuke, na nyocha ugbu a na-elekwasị anya n'ịkwalite arụmọrụ ya na ịgbasa ngwa ya. Na mgbakwunye, a na-atụ anya na ọganihu na usoro nrụpụta na teknụzụ imepụta ga-ebuli arụmọrụ yana ọnụ ahịa nke mgbakwunye HPMC, na-eme ka nnabata ha zuru ebe niile na ọrụ owuwu n'ofe ụwa na-esiwanye ike.
Ihe mgbakwunye Hydroxypropyl methylcellulose (HPMC) na-arụ ọrụ dị mkpa n'ịkwalite njirimara na arụmọrụ nke ihe simenti na ngwa owuwu. Site na nrụpụta ka mma na njigide mmiri ruo nkwudo na ogologo oge, HPMC na-enye ọtụtụ uru na-enyere aka melite ogo, nkwado na ogologo ndụ nke gburugburu ebe e wuru. Ka ụlọ ọrụ na-ewu ụlọ na-aga n'ihu na-ebute nkwado na ihe ọhụrụ, HPMC na-atụ anya na ọ ga-anọgide na-abụ isi ihe na-emepụta ihe na-arụ ọrụ dị elu, na gburugburu ebe obibi.
