1. Okwu mmalite:
N'akụkụ ihe owuwu na ihe owuwu, ịdịte aka bụ ihe kacha mkpa. A na-edobe ihe owuwu ụlọ dị iche iche na gburugburu ebe obibi dị ka mmiri mmiri, mgbanwe okpomọkụ, na nrụgide anụ ahụ, ihe niile nwere ike imebi iguzosi ike n'ezi ihe ha ka oge na-aga. Hydroxypropyl Methylcellulose (HPMC) na-apụta dị ka ihe mgbakwunye dị mkpa na ihe owuwu ihe, na-enye ọtụtụ uru na-eme ka ọ dị ogologo ndụ. Edemede a na-abanye n'ime usoro nke HPMC na-eme ka ogologo ndụ dị ogologo na resilience nke ihe ụlọ, na-esi na konkịtị gaa na adhesives.
2. Ịghọta HPMC:
HPMC bụ polymer vasatail ewepụtara site na cellulose, nke a na-arụ n'ọrụ n'ọtụtụ ebe na-ewu n'ihi ihe ndị pụrụ iche ya. Ọ na-arụ ọrụ dị ka onye na-ejigide mmiri, onye na-ebu ibu, ihe nkedo, na rheology modifier, na-eme ka ọ baa uru n'ofe ngwa dị iche iche. Ọdịdị molekụla nke HPMC na-enyere ya aka ịmepụta njikọ hydrogen na ụmụ irighiri mmiri, na-eduga n'ịdị mma hydration na ịrụ ọrụ na ngwakọta ihe owuwu.
3.Enwekwara ike ịrụ ọrụ na ịdị n'otu na kọmpụta:
Concrete, ihe eji ewu ụlọ, na-erite uru dị ukwuu site na ntinye nke HPMC. Site n'ịhazi ọdịnaya mmiri na ịkwalite akụrụngwa rheological, HPMC na-eme ka arụ ọrụ nke ngwakọta ihe dị mma. Nke a na-ebute njikọ dị mma n'etiti ụmụ irighiri ihe, na-ebelata nkewa na ọbara ọgbụgba n'oge ntinye. Mmiri mmiri a na-achịkwa nke HPMC na-akwadokwa na-enye aka n'ịmepụta ihe owuwu denser na-ebelata ikike, si otú a na-eme ka iguzogide ọgụ kemịkalụ na usoro ikpochapụ.
4. Mbelata nke mgbawa na mbelata:
Mgbawa na mbelata na-ebute nnukwu ihe ịma aka na ịdịte aka nke ihe owuwu. HPMC na-eje ozi dị ka ihe dị irè shrinkage-ebelata admixture (SRA), ibelata mmepe nke cracks kpatara ihicha shrinkage. Site n'ịchịkwa ọnụ ọgụgụ nke mfu mmiri na ịkwalite hydration otu, HPMC na-ebelata nrụgide dị n'ime n'ime matriks kọmpụta, si otú ahụ na-eme ka nguzogide ya na mgbawa na ịbawanye ndụ ọrụ.
5.Mmelite arụmọrụ nrapado:
N'ebe adhesives na ngwa agha, HPMC na-arụ ọrụ dị oke mkpa n'ịkwalite ike na ịdịte aka. Dị ka ihe na-eme ka ọ dị arọ, ọ na-enye nkwụsi ike na nkwụsi ike na usoro nrapado, na-egbochi ịla azụ na ịgba mbọ hụ na ngwa otu. Ọzọkwa, HPMC na-eme ka mmiri mmiri dị mma nke ọma, na-akwalite adhesion na ibelata oghere na interface ahụ. Nke a na-ebute njikọ siri ike nke na-anagide mkpughe gburugburu ebe obibi na ibu ọrụ ka oge na-aga, si otú a na-agbatị ndụ nke mgbakọ jikọtara ọnụ.
6.waterproofing na moisture Management:
Mbanye mmiri bụ ihe na-akpatakarị mmebi na ihe ụlọ. HPMC na-enyere aka na ngwa mkpuchi mmiri site n'ịme ihe mgbochi megide ntinye mmiri. Na mkpuchi mkpuchi mmiri na mkpuchi, HPMC na-eje ozi dị ka onye na-emepụta ihe nkiri, na-emepụta ihe mgbochi na-egbochi mmiri ma na-egbochi uto nke ebu na mildew. Tụkwasị na nke a, ihe mkpuchi na grouts dabeere na HPMC na-enye ezigbo mmachi na ihe ndị na-emepụta ihe, na-emechi nkwonkwo na mgbawa nke ọma iji gbochie ntinye mmiri ma hụ na ọ ga-adị ogologo oge.
7.Enwekwara arụmọrụ na Mpụga mkpuchi na Sistemụ Nchacha (EIFS):
Mwepu mkpuchi na sistemụ mmecha (EIFS) dabere na HPMC iji kwalite ịdịte aka na nguzogide ihu igwe. Dị ka akụkụ bụ isi na uwe mkpuchi na imecha, HPMC na-eme ka arụmọrụ na adhesion dịkwuo mma, na-enye ohere maka ngwa ngwa nke EIFS na-enweghị ntụpọ. Ọzọkwa, usoro EIFS dabeere na HPMC na-egosipụta nkwụsi ike mgbape dị elu yana nkwụsi ike nke okpomọkụ, na-eme ka arụmọrụ dị mma na ọnọdụ ihu igwe dị iche iche.
Hydroxypropyl Methylcellulose (HPMC) na-eguzo dị ka isi nkuku n'ọchịchọ maka ihe owuwu ụlọ na-adịgide adịgide na nke na-adịgide adịgide. Ngwongwo ya nwere otutu ihe na-enyere ya aka ịkwalite arụmọrụ nke kọnkịta, nrapado, usoro mkpuchi mmiri, na EIFS, n'etiti ngwa ndị ọzọ. Site n'ịkwalite arụmọrụ, ibelata mgbawa na mbelata, na ịkwalite njikwa mmiri, HPMC na-atụnye ụtụ nke ukwuu n'ịdị ogologo ndụ na nkwado nke ọrụ ihe owuwu. Dị ka ụlọ ọrụ na-ewu ụlọ na-aga n'ihu na-ebute ogologo oge na ịrụ ọrụ, ọrụ HPMC dị njikere ịgbasa, na-ebuwanye ihe ọhụrụ na ịdị mma na ihe owuwu ụlọ n'ụwa nile.
