Hydroxypropyl Methylcellulose (HPMC) bụ ngwakọta polymer nke a na-ejikarị eme ihe na ihe owuwu ụlọ, ọkachasị na nrapado tile, grout tile na ihe ndị ọzọ sitere na ciment. Isi ọrụ ya na ngwaahịa ndị a gụnyere ịgba, njide mmiri, imeziwanye arụmọrụ ihe owuwu yana ịbawanye ike njikọ.
1. Mmetụta mmetụta
HPMC nwere ikike ịgbatị nke ọma, nke na-enyere ya aka ịhazigharị mmiri na ihe owuwu nke ihe dị na nrapado tile. Site n'ịbawanye viscosity nke adhesives tile, HPMC nwere ike igbochi ihe ahụ site na ịsagharị, sliding ma ọ bụ na-asọpụta n'oge a na-ewu ụlọ, si otú ahụ na-eme ka nkwụsi ike nke ihe owuwu ụlọ. Nke a dị mkpa karịsịa maka owuwu nke facade facade, n'ihi na mgbe ị na-arụ ọrụ na facade, nrapado na-adị mfe na ike ndọda ma na-akpata sagging.
2. Mmetụta njide mmiri
Ọrụ ọzọ dị mkpa nke HPMC bụ ọmarịcha njide mmiri ya. Ihe ndị dabeere na ciment kwesịrị ịnọgide na-enwe ụfọdụ mmiri mmiri n'oge a na-ewu iji hụ na mmeghachi omume hydration nke ciment na-arụ ọrụ zuru oke. HPMC nwere ike igbachi mmiri n'ụzọ dị irè, gbatịa oge ịdị adị nke mmiri dị n'ime ihe ahụ, ma gbochie mmiri ịla n'iyi ngwa ngwa, ọkachasị na gburugburu ebe ọkụ na nkụ. Ọganihu nke njide mmiri nwere ike ibelata ihe omume nke mgbawa, mee ka ike nke njikọ dị n'etiti nrapado na oyi akwa isi, ma hụ na ciment na-eme ka mmiri dị ọcha, si otú a na-eme ka ike ikpeazụ na ịdịte aka.
3. Meziwanye ihe owuwu ihe owuwu
Mgbakwunye nke HPMC nwere ike imeziwanye arụmọrụ ụlọ nke nrapado na grouts. Nke mbụ, ọ nwere ike ime ka mmanu nke ihe ahụ dịkwuo mma, na-eme ka trowel dị nro n'oge a na-ewu ihe, na-ebelata nguzogide na adhesion n'oge a na-ewu ụlọ, na imeziwanye arụmọrụ ụlọ. Nke abuo, HPMC nwekwara ike melite thixotropy nke ihe onwunwe, ya bụ, ihe onwunwe na-ejigide a ụfọdụ agbanwe agbanwe mgbe ọ na-eguzo, na-aghọ mfe na-asọpụta mgbe ọ na-mmetụta, nke na-enyere mma nke ọrụ n'oge ewu.
4. Meziwanye ike njikọta
Ngwa nke HPMC nwekwara ike imeziwanye ike njikọ nke tile adhesives. Site na njide mmiri, HPMC na-eme ka hydration zuru oke nke ciment, nke metụtara mmezi nke ike njikọ. Tụkwasị na nke ahụ, mmetụta ndị na-esi ísì ụtọ na mmanye nke HPMC na-enye ohere ka a na-etinye nrapado ahụ n'azụ taịl na elu nke mkpụrụ ahụ, si otú ahụ na-enweta njikọ dị n'otu na nke siri ike. Ọrụ a nke HPMC dị mkpa karịsịa maka nnukwu taịlị ma ọ bụ taịlị ndị nwere obere mmịnye mmiri.
5. Kwalite arụmọrụ mgbochi sagging
HPMC nwekwara ike melite arụmọrụ mgbochi sagging nke adhesives na grouts. Sagging na-ezo aka n'ihe na-eme na nrapado ma ọ bụ grout na-agbadata ala n'ihi ike ndọda n'oge a na-ewu facade. Mmetụta siri ike nke HPMC nwere ike igbochi ihe omume a nke ọma ma hụ na nkwụsi ike nke ihe dị na elu kwụ ọtọ, si otú ahụ belata ohere nke mmebi ihe owuwu na ịrụ ọrụ.
6. Melite nguzogide friza-thaws
Maka ụfọdụ ihe eji arụ ụlọ nke a ga-eji na gburugburu ebe okpomọkụ dị ala, HPMC nwekwara ogo ụfọdụ nke nguzogide ntu oyi. Nke a pụtara na mgbe multiple ifriizi-thaw cycles, ihe na-eji HPMC ka nwere ike ịnọgide na-enwe ezi arụmọrụ na-agaghị ịgbawa ma ọ bụ nkekọ ọdịda n'ihi na ala okpomọkụ.
7. Nchekwa gburugburu ebe obibi na nchekwa
Dị ka ihe na-adịghị egbu egbu na nke na-adịghị emerụ ahụ, iji HPMC na-arụ ọrụ n'ime usoro ihe owuwu na-emezukwa ihe nchebe gburugburu ebe obibi na ihe nchekwa chọrọ nke ihe ụlọ ọgbara ọhụrụ. Ọ naghị ahapụ ikuku ndị na-emerụ ahụ ma dị mfe ijikwa ihe mkpofu ihe owuwu, ya mere ejirila ya mee ihe n'ọtụtụ ebe.
Hydroxypropyl methylcellulose (HPMC) na-arụ ọtụtụ ọrụ dị mkpa na ngwa tile, gụnyere ịgbakọ, njigide mmiri, imeziwanye arụmọrụ ihe owuwu, kwalite ike njikọ, na-eme ka arụmọrụ mgbochi na-abawanye, yana melite nguzogide ntu oyi. Ngwongwo ndị a na-eme ka ojiji nke tile adhesives na grouts dịkwuo mma, si otú ahụ na-eme ka nkwụsi ike na ịdịte aka nke ihe owuwu ụlọ. Ya mere, HPMC abụrụla ihe mgbakwunye dị mkpa na ihe dị mkpa na ihe ụlọ ọgbara ọhụrụ.
