HPMC (hydroxypropyl methylcellulose) bụ ihe a na-ejikarị cellulose ether eme ihe nke a na-ejikarị eme ihe n'ụlọ, karịsịa na-arụ ọrụ dị mkpa na ngwa agha. Ngwa ngwa HPMC gbanwetụrụ bụ ihe eji arụ ụlọ na-agbakwunye HPMC dịka mgbakwunye na ngwa agha ọdịnala. Ọ nwere ọtụtụ ihe eji eme ihe ma nwee nnukwu uru na ọrụ owuwu.
1. kwalite ịrụ ọrụ ihe owuwu
Ngwa ngwa HPMC gbanwetụrụ na-egosi arụmọrụ ụlọ dị elu n'oge usoro ihe owuwu. Nke mbụ, HPMC nwere ike melite njide mmiri nke ngwa agha. N'ime ngwa agha ọdịnala, mmiri na-apụ ngwa ngwa ma ọ bụ na-etinye ya n'ahụ site na ihe ndị dị na ya, na-eme ka ngwa agha ahụ ghara iru mmiri zuru oke tupu ọ gbasie ike, na-emetụta ike ya na ịdịte aka ya. Site na imeziwanye ikike njigide mmiri nke ngwa agha, HPMC na-ahụ na ngwa agha ahụ nwere mmiri zuru oke iji sonye na mmeghachi omume hydration n'oge usoro siri ike, si otú ahụ na-eme ka ike ikpeazụ na ịdịte aka.
Nke abuo, HPMC nwere ike melite workability nke ngwa agha. HPMC nwere mmetụta na-eme ka ọ dị arọ na mmanu mmanu, na-eme ka ngwa agha dị mfe ịrụ. Karịsịa mgbe ị na-arụ ọrụ n'elu mgbidi ma ọ bụ n'ebe dị elu, a na-eme ka mmiri na nchikota nke ngwa agha dịkwuo mma, na-ebelata ihe isi ike ihe owuwu na ike ọrụ. N'otu oge ahụ, HPMC nwere ike kesaa ngwa agha ahụ nke ọma, belata delamination na nkewa nke ngwa agha mgbe a na-eji ya eme ihe, ma melite ogo ụlọ nke ngwa agha ahụ.
2. Melite arụmọrụ njikọ
Ngwa ngwa HPMC gbanwere na-egosikwa uru dị ukwuu na arụmọrụ njikọ. Ngwa agha ọdịnala nwere oke nrapanye na ihe mgbakwasị ụkwụ mgbe ọ gwọchara ya, ọ na-enwekwa ike inwe nsogbu dị ka oghere na mgbawa. Mgbe ịgbakwunye HPMC, njikọ ike nke ngwa agha na-akawanye mma ma ọ nwere ike ịrapara n'elu ala dị iche iche. Ma ọ bụ kọnkịrị, masonry ma ọ bụ ihe ụlọ ndị ọzọ, ngwa agha gbanwere HPMC nwere ike ịmepụta oyi akwa njikọ siri ike. gbochie oghere na mgbawa nke ọma.
Na mgbakwunye, HPMC nwekwara ike melite arụmọrụ mgbochi nke ngwa agha. Karịsịa mgbe ị na-edobe taịlị ma ọ bụ nkume seramiiki, ngwa agha agbanwere HPMC nwere ike igbochi mwepu nke taịlị ma ọ bụ nkume seramiiki ma hụ na ịdị nro na nkwụsi ike ka emechara. Nke a nwere uru ngwa dị mkpa maka ọrụ ịchọ mma dị elu, dị ka usoro nkume akọrọ akọrọ na mgbidi mpụta ma ọ bụ nnukwu ceramic tiles na ala.
3. Meziwanye nkwụsị mgbape
HPMC gbanwetụrụ ngwa agha nwere ọmarịcha mgbape nguzogide. Ịtinye HPMC na ngwa agha nwere ike igbochi nguzobe nke cracks nke ọma. HPMC na-ebelata ikuku mmiri ngwa ngwa site na imeziwanye njide mmiri nke ngwa agha, si otú ahụ belata nrụgide shrinkage ihicha nke mmiri na-efunahụ kpatara. Nke a dị mkpa karịsịa maka nnukwu owuwu ma ọ bụ ụlọ ndị na-ekpuchi ọnọdụ akọrọ ruo ogologo oge.
Na mgbakwunye, mmetụta siri ike nke HPMC na-enyekwa aka kwalite nguzogide mgbape nke ngwa agha. HPMC nwere ike mepụta ụfọdụ microscopic eriri netwọk Ọdịdị n'ime ngwa agha na-abawanye ike nke ngwa agha, si otú iguzogide mpụga nchegbu na ibelata omume nke cracks. Karịsịa na mpụta mgbidi mkpuchi usoro, mgbape eguzogide nke HPMC modified ngwa agha na-arụ a isi ọrụ na-eme ka mkpokọta anwụ ngwa ngwa nke usoro.
4. Meziwanye nguzogide ihu igwe
Ngwa ngwa HPMC gbanwetụrụ nwekwara ezigbo nguzogide ihu igwe ma nwee ike ịnọgide na-arụ ọrụ kwụsiri ike n'okpuru ọnọdụ ihu igwe siri ike dị iche iche. Mgbakwunye nke HPMC na-eme ka ngwa agha ahụ nwee nkwụsi ike na-ajụ oyi na nguzogide UV, na-agbatị ndụ ọrụ nke ngwa agha ahụ. N'ebe oyi na-atụ, ngwa ngwa HPMC gbanwetụrụ nwere ike iguzogide mmebi nke okirikiri ifriizi ma gbochie ịpụpụ friza n'elu ngwa agha.
N'otu oge ahụ, HPMC nwekwara ike melite impermeability nke ngwa agha iji gbochie ntinye nke mmiri na ihe ndị ọzọ na-emerụ ahụ, si otú ahụ na-echebe ihe owuwu ụlọ site na mmebi na mmebi. Nke a na-eme ka ngwa agha HPMC gbanwetụrụ dabara adaba maka mgbochi mmiri nke mpụga, mkpuchi mmiri na ọrụ ndị ọzọ iji hụ na ịdịte aka na nchekwa nke ụlọ ahụ dị ogologo.
5. Nchekwa gburugburu ebe obibi na mmepe na-adịgide adịgide
N'ikpeazụ, HPMC gbanwetụrụ ngwa agha nwere ezigbo arụmọrụ gburugburu ebe obibi. HPMC bụ ihe na-adịghị egbu egbu, akwụkwọ ndụ akwụkwọ ndụ na-adịghị emerụ ahụ nke na-agaghị ebute mmetọ na gburugburu ebe obibi. N'otu oge ahụ, ngwa agha HPMC gbanwere nwere ike ibelata ọnụ ọgụgụ ciment a na-eji n'oge mmepụta na ojiji, belata ikuku carbon dioxide, ma nyere ụlọ ọrụ ihe owuwu aka inweta mmepe na-adigide.
Ịrụ ọrụ owuwu nke ọma na ịdịte aka nke ngwa agha agbanwere HPMC nwere ike ibelata mkpofu ihe owuwu ụlọ na ụgwọ ọrụ, na-egosipụtakwa uru gburugburu ya. Nke a nwere uru bara uru dị mkpa na ọnọdụ ugbu a nke ịkwalite ụlọ akwụkwọ ndụ akwụkwọ ndụ na akụ na ụba carbon dị ala.
Ngwa ngwa HPMC gbanwetụrụ nwere ọtụtụ ojiji yana uru arụmọrụ dị ukwuu na ọrụ owuwu. Ngwa ngwa HPMC gbanwetụrụ egosila nsonaazụ dị mma n'ihe gbasara arụmọrụ ụlọ, arụmọrụ njikọta, mgbape mgbape na nguzogide ihu igwe. N'otu oge ahụ, nchebe gburugburu ebe obibi ya na njirimara mmepe mmepe na-emekwa ka ọ bụrụ akụkụ dị mkpa nke ihe owuwu ụlọ nke oge a. Site na mmepe nke teknụzụ ihe owuwu na-aga n'ihu na mmụba nke ahịa ahịa na-aga n'ihu, atụmanya ngwa nke ngwa ngwa gbanwetụrụ HPMC ga-abawanye.
