I-HPMC (i-Hydroxypropylmethylcellulose) iphuma ku-cellulose evamise ukusetshenziswa ezintweni zokwakha, ikakhulukazi usimende noma amapulasi asekelwe ku-gypsum namaplasta. Kuyisithasiselo esisebenza ngezinto eziningi esithuthukisa ukusebenza kwalezi zinto futhi sithuthukise izakhiwo zazo. I-HPMC iyi-polymer encibilikayo emanzini engahlakazwa kalula emanzini ukuze yakhe isixazululo esiwugqinsi, esilinganayo.
Kulesi sihloko, sihlola izinzuzo ezihlukahlukene zokusebenzisa i-HPMC kusimende noma kumapulasi asekelwe ku-gypsum namapulasi.
Thuthukisa ukusebenza
Enye yezinzuzo eziyinhloko zokusebenzisa i-HPMC kusimende noma kumapulasi asekelwe ku-gypsum kanye nokhonkolo wukusebenza kwayo okuthuthukisiwe. Ukucutshungulwa kubhekisela ekukhululekeni kwezinto ezingaxutshwa, zisetshenziswe futhi zicutshungulwe. I-HPMC isebenza njengesithambiso, ithuthukisa ukugeleza nokusabalala kwempahla, ikwenze kube lula ukuyifaka kanye nesiphetho esishelelayo.
Ukuba khona kwe-HPMC kule nhlanganisela kunciphisa isidingo samanzi sempahla, esiza ukulawula ukushwabana nokuqhekeka ngesikhathi somiswa. Lokhu kusho ukuthi impahla izogcina ukwakheka nosayizi wayo futhi ngeke iqhekeke noma inciphe ngenxa yokulahlekelwa umswakama.
Thuthukisa ukunamathela
I-HPMC ingaphinde ithuthukise ukunamathela kanye nokunikeza usimende noma amapulasi asekelwe ku-gypsum endaweni engaphansi. Lokhu kungenxa yokuthi i-HPMC yenza ifilimu elincanyana endaweni engaphansi esebenza njengesithiyo somswakama futhi ivimbele ukhonkolo ekuxebukeni noma ukuhlukana ne-substrate.
Ifilimu eyakhiwe yi-HPMC iphinde ithuthukise isibopho sokhonkolo ku-substrate ngokwenza uphawu oluqinile phakathi kwakho kokubili. Lokhu kwandisa amandla awo wonke kanye nokuqina kwe-plaster, okwenza kube mancane amathuba okuthi iqhekeke noma ibhidlike.
Thuthukisa ukumelana nesimo sezulu
Izikhonkwane ezisekelwe kusimende noma ze-gypsum namapulasi aqukethe i-HPMC amelana kakhulu nesimo sezulu kanye nokuguguleka. Lokhu kungenxa yokuthi i-HPMC yakha ifilimu yokuvikela phezu kokhonkolo exosha amanzi futhi ivimbele umswakama ukuthi ungangeni ezintweni.
Ifilimu eyakhiwe yi-HPMC yenza futhi i-gypsum ukuthi imelane kakhulu nemisebe ye-UV nezinye izinhlobo zesimo sezulu, ivikele emonakalweni obangelwa ilanga, umoya, imvula nezinye izakhi zemvelo.
Ukuqina okwenyuka
Ukwengeza i-HPMC kusimende noma kumapulastele asekelwe ku-gypsum kuthuthukisa ukuqina kwawo kukonke. Lokhu kungenxa yokuthi i-HPMC inyusa ukuguquguquka nokunwebeka kokhonkolo, ikwenze kube mancane amathuba okuqhekeka noma ukuphuka. I-HPMC iphinda inyuse ukuguga nomthelela wokumelana kwento, iyenze imelane kakhulu nokuhuzuka.
Ukuqina okwenyuka kwempahla nakho kuyenza imelane kakhulu nomonakalo wamanzi njengokungena kwamanzi, umswakama nokukhula kwesikhunta. Lokhu kuyenza ibe impahla ekahle ukuthi isetshenziswe ezindaweni ezimanzi njengezindlu zangasese, amakhishi nezindlu zangaphansi.
Thuthukisa ukumelana nomlilo
Izikhonkwane ezisekelwe kusimende noma i-gypsum namapulasi aqukethe i-HPMC aqinile kakhulu kunalawo angenayo i-HPMC. Lokhu kungenxa yokuthi i-HPMC yenza ungqimba oluvikelayo phezu kokhonkolo olusiza ukulivimbela ukuthi lingashi noma lisakaze ilangabi.
Ukuba khona kwe-HPMC engxubeni nakho kuthuthukisa izakhiwo zokushisa ezishisayo ze-plaster. Lokhu kusiza ekuvimbeleni ukushisa kungangeni kusimende, okungasiza ekubambezeleni ukubhebhetheka komlilo.
Ekuphetheni
I-HPMC iyisengezo esisebenza ngezinto eziningi esisetshenziswa kakhulu ezintweni zokwakha, ikakhulukazi usimende noma amapulasi asekelwe ku-gypsum namapulasi. Ihlinzeka ngezinzuzo eziningi ezihlanganisa ukucutshungulwa okuthuthukisiwe, ukunamathela okuthuthukisiwe, isimo sezulu esithuthukisiwe, ukuqina okuthuthukisiwe kanye nokumelana nomlilo okuthuthukisiwe.
Ukusebenzisa i-HPMC kumapulasi asekelwe kusimende noma ku-gypsum kungasiza ukuthuthukisa ukusebenza nokuphila isikhathi eside kwalezi zinto, kuzenze zimelane kakhulu nokugqokwa kanye nezakhi. Ilungele osonkontileka nabakhi abafuna ukuqinisekisa ikhwalithi nokuqina kwephrojekthi eqediwe.
