Hydroxypropyl Methylcellulose (HPMC) bụ cellulose ether dị mkpa nke nwere ọtụtụ ngwa na ụlọ ọrụ ihe owuwu. Ọ bụ ngwakọta polymer na-agbaze mmiri nke enwetara site na-agbanwe cellulose eke ekemịkalụ. Ọ nwere ezigbo mmiri solubility, ndina, imepụta ihe nkiri, njikọta, mmanu na njirimara ndị ọzọ, ya mere ọ na-arụ ọrụ dị iche iche na-arụ ọrụ ụlọ.
1. Simenti ngwa agha na ihe
N'ime ngwa simenti na kọnkịta, a na-eji HPMC eme ihe dị ka ihe na-ekpo ọkụ, ihe na-ejide mmiri na ihe nkedo. Isi ọrụ ya gụnyere:
Mmetụta siri ike: HPMC nwere ike ịbawanye viscosity nke ngwa ngwa ciment ma ọ bụ ihe, si otú a na-emeziwanye arụmọrụ ihe owuwu na ime ka ọ dịkwuo mfe ịgbasa na ịrụ ọrụ. Tụkwasị na nke ahụ, ngwa agha ahụ gbara ọkpụrụkpụ nwere ike ịrapagidesi ike na mkpụrụ osisi ahụ ma belata ohere nke ntụ ntụ na ịdapụ.
Mmetụta njide mmiri: HPMC nwere ikike njigide mmiri siri ike, nke nwere ike ibelata mmiri na-efu na ngwa ngwa ma ọ bụ ihe, na-agbatị oge mmeghachi omume hydration nke ciment, ma si otú ahụ mee ka ike ikpeazụ na ịdịte aka. Njirimara a dị mkpa karịsịa na ebe akọrọ ma ọ bụ okpomọkụ dị elu, n'ihi na ọ nwere ike igbochi mgbawa na ike na-ezughị ezu nke ihicha simenti na-akaghị aka.
Mmetụta na-egbochi sagging: Mgbe ị na-arụ ọrụ n'elu kwụ ọtọ, HPMC nwere ike igbochi ngwa agha ma ọ bụ mkpuchi ịkwada ala, na-ejigide ọkpụrụkpụ otu na ezigbo mkpuchi.
2. Tile adhesives
Na nrapado tile, ọrụ HPMC dị oke egwu. Ọ bụghị naanị na ọ na-eme ka adhesion nke nrapado na-eme ka ọ dịkwuo mma, kamakwa ọ na-eme ka ọrụ ahụ dịkwuo mma n'oge a na-ewu ya. Kpọmkwem, a na-egosipụta ya dị ka ndị a:
Ịkwalite adhesion: HPMC na-eme ka adhesion dị n'etiti taịlị na taịlị na ihe ndị na-emepụta ihe, na-eme ka nkwụsi ike na ịdịte aka nke taịlị mgbe ịtọsịrị.
Ịmalite ịrụ ọrụ ihe owuwu: HPMC nwere ike ịbawanye oge mmeghe nke adhesives tile, ya bụ, ịgbatị oge a ga-edozi ọnọdụ nke taịlị tupu akọrọ akọrọ, nke dị ezigbo mkpa maka ndị na-arụ ọrụ na-ewu ụlọ ma nwee ike hụ na ọ bụ ihe ziri ezi nke ịtọgbọ tile.
Mgbochi slip: Maka taịlị ndị buru ibu ma ọ bụ mgbe a na-arụ ya n'elu kwụ ọtọ, HPMC nwere ike igbochi mwepu nke taịlị, si otú a na-emeziwanye ogo ihe owuwu.
3. Usoro mkpuchi mgbidi mpụga
N'ime usoro mkpuchi mgbidi dị n'èzí, HPMC na-arụkwa ọrụ nke njide mmiri, ịgbanye na njikọ. Usoro mkpuchi nke dị n'èzí na-achọ ka ihe owuwu ahụ nwee ezigbo njide mmiri iji jide n'aka na ngwa agha njikọ agaghị ada n'ihi oke mmiri na-efunahụ n'oge a na-ewu ụlọ na ọgwụgwọ. Mgbakwunye nke HPMC na-eme ka arụ ọrụ, mkpuchi na nkwụsị mgbawa nke ngwa agha ahụ dịkwuo mma, si otú ahụ na-eme ka mma ụlọ na ịdịte aka nke usoro mkpuchi ahụ dum.
4. Ihe n'ala na-edozi onwe ya
N'ime ihe n'ala na-edozi onwe ya, HPMC na-arụ ọrụ nke ịhazi mmiri mmiri na imeziwanye njide mmiri. Ihe a na-achọ ọkwa n'oge a na-ewu ụlọ, ma ọ nweghị ike ịmepụta oke sedimentation ma ọ bụ stratification. Mmetụta siri ike nke HPMC nwere ike ịnọgide na-enwe otu ihe ahụ na-enweghị emetụta mmiri mmiri, na-eme ka ala ala dị larịị ma dị mma.
5. Putty ntụ ntụ
A na-ejikwa HPMC n'ọtụtụ ebe na ntụ ntụ ntụ maka ime na mgbidi nke ụlọ. Ọ nwere ike imeziwanye ihe owuwu na ịdịte aka nke ntụ ntụ putty, welie njikọ ya na mgbidi, ma melite oge ihicha na nkwụsị mgbawa nke ntụ ntụ putty. Karịsịa na ihu igwe kpọrọ nkụ, HPMC nwere ike igbochi mgbawa elu ma ọ bụ daa nke ọma site na mfu mmiri ngwa ngwa nke ntụ ntụ putty.
6. Ngwa ndị ọzọ
Na mgbakwunye na isi ihe ndị dị n'elu, HPMC na-ekerekwa òkè n'akụkụ ndị ọzọ nke ihe owuwu, dị ka ngwaahịa gypsum, mkpuchi mmiri, ihe ndị na-emepụta ihe, ihe mkpuchi, wdg. Ya multifunctional Njirimara dị ka ndim, mmiri njide, na bonding-eme ka ọ isi ihe mgbakwunye na ihe owuwu ụlọ.
Hydroxypropyl methylcellulose nwere ọtụtụ ngwa dị mkpa na ụlọ ọrụ ihe owuwu. Ọ na-eme ka mma na ịrụ ọrụ nke ọma na-arụ ọrụ nke ọma na-arụ ọrụ nke ọma site n'ịkwalite ịrụ ọrụ nke ciment dabeere na gypsum, ịgbatị oge ọrụ, na-eme ka njikọ dị mma, na imeziwanye nkwụsị mgbape. Ya mere, atụmanya ngwa nke HPMC na ihe owuwu nke oge a dị nnọọ ukwuu, na site na mmepe nke teknụzụ ihe owuwu na-aga n'ihu, ọrụ HPMC ga-abụ nke a ma ama.
