Isingeniso:
I-Hydroxypropyl Methylcellulose (HPMC) iyingxenye eguquguqukayo esetshenziswa kabanzi kwizimboni zokwakha ngekhono layo lokuthuthukisa ukuqina kwezinto zokwakha.
Ukuqonda i-Hydroxypropyllykyl methylcellulose (HPMC):
I-HPMC iyindawo yokwenziwa ethathwe ku-cellulose, i-polymer yemvelo etholakala ezitshalweni. Kukhiqizwa ngokuguqulwa kwamakhemikhali kwe-cellulose, okuholele ku-polymer engenamanzi enezakhiwo ezihlukile. I-HPMC ibonakala ngamandla ayo okugcina amanzi aphezulu, amandla akha amafilimu, kanye nokunamathela okuhle kuma-substrate ahlukahlukene.
Izindlela zokuthuthuka kokuqina:
Ukugcinwa kwamanzi: Enye yezindlela eziyinhloko lapho i-HPMC ithuthukisa ukuqina yikhono layo lokugcina amanzi ngaphakathi kwezinto zokwakha. Ngokwakha ifilimu evikelayo phezu kwe-surface, i-HPMC yehlisa umhwamuko wamanzi, ivimbela ukomiswa ngaphambi kwesikhathi kanye ne-shrinkage. Lokhu kubalulekile ikakhulukazi ezintweni eziqinisekisiwe, lapho i-hydration eyanele ibalulekile ukuze ifinyelele amandla aphezulu nokuqina.
Ukusebenza okwenziwe ngcono: I-HPMC isebenza njengokushintsha kwe-Rheology, okwenza ngcono ukusebenziseka kwezinto zokwakha ezifana nodaka, ama-grouts, kanye nokuhumusha. Ukuba khona kwayo kuthuthukisa ukuvumelana nokusakazeka kwalezi zingxube, okuvumela uhlelo lokusebenza olulula futhi kunciphise amathuba okuhlukaniswa noma ukuqhekeka ngesikhathi sokubekwa.
Isikhangiso esithuthukisiwe: I-HPMC ithuthukisa ukunamathela kwezimbozo, ukunamathela kanye nama-sealants ku-substrates, ngaleyo ndlela kuthuthukise amandla ebhondi wonke nokuqina kwalezi zinhlelo. Lokhu kuzuzisa kakhulu izinhlelo zokusebenza ezingaphindi, lapho ukunamathela okuqinile kubalulekile ekuvikeleni ukungena kwamanzi nokugcina ubuqotho bezinhlekelele ngokuhamba kwesikhathi.
Izicelo ezintweni zokwakha:
Abakwa-Cement-based Morning kanye noDinder: I-HPMC ivame ukusetshenziswa njengezengezo ku-donperative kuma-matuements osomakhelwane kanye nokwenziwa ngcono ukuthuthukisa ukusebenza, ukunamathela, kanye nokugcinwa kwamanzi. Ngokufaka i-HPMC kulezi zingxube, osonkontileka bangafinyelela ukuqeda okubushelelezi, banciphise ukuqhekeka, futhi bathuthukise ukuqina kwesikhathi eside.
Adhesives tile anamathela kanye ne-grouts: Ku-tile Ukufakwa kwezicelo, i-HPMC yengezwa ezinamatheyisi nama-grouts ukuthuthukisa amandla e-bond futhi ivikele ukungena kwamanzi. Izakhiwo zalo zokugcina amanzi ziqinisekisa i-hydration efanelekile yama-adhesives aqinisekisiwe, kanti amandla ayo akha amafilimu kuthuthukisa ukuqina kwamajoyinti e-grout, anciphise ubungozi bokubala nokuwohloka.
Imikhiqizo esekwe eGypsum: I-HPMC ithola ukusetshenziswa okubanzi emikhiqizweni esekwe ku-gypsum efana namakhompiyutha ahlanganayo kanye nama-polasters. Ngokwenza ngcono ukusebenziseka nokugcinwa kwamanzi, i-HPMC inika amandla okubushelela ukusetshenziswa kwezikhathi nezikhathi zokumisa ngokushesha, okuholela ekuphelekeni okuphezulu okuphezulu ngokuqina okuthuthukile.
Ukufakwa kwangaphandle kanye nezinhlelo zokuqeda (ama-EIF): Kuzinhlelo zokusebenza ze-EIFS, i-HPMC isetshenziselwa ukuthuthukisa ukusebenza kwamajazi, anamathela, kanye namajazi. Amandla alo okuthuthukisa ukunamathela, ukumelana kwamanzi, kanye nokumelana nokuqhekeka kwenza kube yisengezo esisemqoka ekufezekiseni izinambuzane ezihlala njalo nezinhle.
I-Hydroxypropyl Methylcellulose (HPMC) idlala indima ebalulekile ekuthuthukiseni ukuqina kwezinto zokwakha ezinhlobonhlobo zokwakha. Ngokufaka izakhiwo zayo ezihlukile, kufaka phakathi ukugcinwa kwamanzi, ukukhiqizwa okuthuthukile, nokunamathela okuthuthukile, i-HPMC inika amandla ukukhiqizwa kwezinto zokwakha eziphezulu ezimelana nobunzima besikhathi nokuvezwa kwezemvelo. Njengoba imboni yezokwakha iyaqhubeka nokubeka phambili ukusimama nokuphila isikhathi eside, isidingo sezixazululo ezisuselwa ku-HPMC kulindeleke ukuthi sikhule, ukushayela okusha kanye nentuthuko ekwakheni ubuchwepheshe bezinto ezibonakalayo.
