IHydroxypropylmethylcellulose (HPMC) iyisithako esibalulekile nesiguquguqukayo esisetshenziswa ezimbonini eziningi okuhlanganisa nebanga le-plaster.I-HPMC iyi-ether ye-cellulose etholakala ku-cellulose futhi iyi-nonionic, i-polymer encibilika emanzini.Ivamise ukusetshenziswa njenge-thickener, stabilizer kanye ne-emulsifier ezimakethe ezimanzi nezomile.Embonini ye-gypsum, i-HPMC isetshenziswa njenge-dispersant kanye ne-thickener.Lesi sihloko sichaza ngezinzuzo zokusebenzisa i-HPMC ekukhiqizeni i-gypsum.
I-Gypsum iyiminerali eyenzeka ngokwemvelo evame ukusetshenziswa embonini yezokwakha ukukhiqiza usimende negypsum.Ukuze wenze imikhiqizo ye-gypsum, i-gypsum kufanele iqale icutshungulwe ibe yimpushana.Inqubo yokwenza i-gypsum powder ihilela ukuchoboza nokugaya amaminerali, bese uyishisa emazingeni okushisa aphezulu ukuze ususe amanzi amaningi.Impushana eyomile ephumayo bese ixutshwa namanzi ukuze yakhe inhlama noma i-slurry.
Enye yezinto ezibaluleke kakhulu ze-HPMC embonini ye-gypsum yikhono layo lokuhlakaza.Emikhiqizweni ye-gypsum, i-HPMC isebenza njengesisabalalisi, ihlukanisa izigaxa zezinhlayiya futhi iqinisekise ukusatshalaliswa kwazo okufanayo kulo lonke udaka.Lokhu kubangela ukunamathisela okubushelelezi, okungaguquki okulula ukusebenza ngakho.
Ngaphezu kokuba yi-disperant, i-HPMC iphinde ibe yi-thickener.Kuyasiza ukukhulisa i-viscosity ye-gypsum slurry, okwenza kube lula ukuphatha nokusebenzisa.Lokhu kubaluleke kakhulu emikhiqizweni edinga ukuqina okuqinile, njengenhlanganisela ehlangene noma ukhonkolo.
Enye inzuzo ebalulekile ye-HPMC embonini ye-gypsum ukusebenza kwayo okuthuthukisiwe.Ukwengeza i-HPMC ku-gypsum slurries kwenza umkhiqizo usabalale kalula futhi usebenze isikhathi eside.Lokhu kusho ukuthi osonkontileka nabantu ngabanye banesikhathi esiningi sokusebenza emkhiqizweni ngaphambi kokuthi uqale.
I-HPMC futhi ithuthukisa ikhwalithi nokuqina komkhiqizo wokugcina.Ngokusebenza njenge-dispersant, i-HPMC iqinisekisa ukuthi izinhlayiya ze-gypsum zisatshalaliswa ngokulinganayo kuwo wonke umkhiqizo.Lokhu kwenza umkhiqizo uhlale isikhathi eside, ungaguquki futhi ungajwayele ukuqhekeka nokuphuka.
I-HPMC iyisithako esihambisana nemvelo.Ayinabuthi, iyabola futhi ayikubangeli ukungcoliswa komoya.Lokhu kwenza kube ukukhetha okuhle kakhulu ezimbonini ezithintekayo mayelana nomthelela wemvelo wemikhiqizo yazo.
I-HPMC iyisithako esibalulekile emndenini wegypsum enezinzuzo eziningi.Ikhono layo lokuhlakaza, ukujiya, ukuthuthukisa ukucutshungulwa kanye nekhwalithi yomkhiqizo wokuphela kwenze kwaba yingxenye ebalulekile yemboni.Ubungane bayo bemvelo buphinde bube yinzuzo ephawulekayo emhlabeni lapho izimboni eziningi zibheke ukunciphisa umthelela wazo kwezemvelo.
Ekuphetheni
IHydroxypropylmethylcellulose (HPMC) iyisithako esibalulekile ebangeni le-plaster.Ikhono layo lokuhlakaza, ukujiya, ukuthuthukisa ukucutshungulwa kanye nekhwalithi yomkhiqizo wokuphela kwenze kwaba yingxenye ebalulekile yemboni.Ngaphezu kwalokho, ubungane bayo bemvelo kuyinzuzo enkulu emhlabeni lapho izimboni eziningi zifuna ukunciphisa umthelela wazo kwezemvelo.Sekukonke, i-HPMC iyisinqumo esihle kakhulu kunoma iyiphi imboni efuna ukuthuthukisa ikhwalithi yemikhiqizo yayo kuyilapho iqaphela umthelela wayo kwezemvelo.
