I-polymer yemvelo hydroxypropyllr methylcellulose kasimende osuselwe ku-plaster esekelwe

I-Hydroxypropylm methylcellulose (HPMC) iyi-polymer yemvelo esetshenziswe kabanzi embonini yezokwakha njengesengezo se-Plaster-based Plaster. Ingasetshenziswa njenge-ejenti yokugcinwa kwamanzi, i-mperener, kanye ne-binder yokuthuthukisa ukusebenza kwama-polsters asuselwa kusawoti.

I-HPMC iyi-polymetic yokwenziwa, enamanzi eyenziwe ngamanzi e-cellulose. Kuthathwe ku-cellulose yemvelo ngenqubo yokuguqulwa kwamakhemikhali ehilela ukwengeza kwe-hydroxypropyl kanye namaqembu we-methyl. Lokhu kuguqulwa kuphumela ku-polymer nge-solubity yamanzi ethuthukisiwe, ukuqina okushisayo, kanye nokumelana kwamakhemikhali.

Ukusetshenziswa kwe-HPMC ekusungulweni kosimende okususelwa ku-cements kunikeza izinzuzo eziningi ezinjengokuthi:

1. Ukusebenza okuthuthukisiwe: I-HPMC isebenza njengokushintsha kwe-Rheology okuthuthukisa ukusebenziseka kanye nezinsiza zohlelo lokusebenza lodaka. Kuthuthukisa ukunamathela, ukubumbana, kanye nokusakazeka kodaka, okuvumela ukuthi kusetshenziswe kalula kwi-substrate.
2. Ukugcinwa kwamanzi okuthuthukile Le mpahla ibuye iqinisekise ukuthi udaka ugcina ukungaguquguquki kwawo nokusebenza kwezikhathi ezinde, ngisho nasemimweni eshisayo neyomile.
3. Ukubumbana okukhulayo kanye nokunamathela: I-HPMC yakha ifilimu ezungeze izinhlayiya zokwenza usimende, okuthuthukisa ukubumbana kwayo kanye nokunamathelisa ku-substrate. Le mpahla iqinisekisa ukuthi udaka luhlala luqinile futhi alunakuqhekeka noma luhlukane ne-substrate.
4. Ukuqhekeka okuncishisiwe: I-HPMC ithuthukisa amandla ashukumisayo kanye nokuguquguquka kodaka, kunciphisa amathuba okuqhekeka ngenxa yokushwabana noma ukunwetshwa.
5. Ukuqina okuthuthukisiwe: I-HPMC ihlinzeka ngodaka ngokumelana nokwenza ngcono kwamanzi kanye nokumelana kwamakhemikhali, okwenza kube nzima kakhulu futhi kuvimbele ekuguleni nasekugugeni.

Ngaphezu kwalezi zinzuzo, i-HPMC nayo iyisengezo esimeme futhi esinobungani esingasiza ekunciphiseni umthelela wezemvelo wabantu basemakamu. Akulona ubuthi, i-biodegradable, futhi ayikhiphi izinto eziyingozi emvelweni.

Ukuze usebenzise i-HPMC kuma-Plasters asuselwa ku-Cement, imvamisa ingezwe ekuxubeni eyomile ka usimende nesihlabathi ngaphambi kokufakwa kwamanzi. Umthamo onconyiwe we-HPMC uyahlukahluka ngokuya ngesicelo esithile kanye nezakhiwo ezifiselekayo zodaka. Ngokuvamile, umthamo we-0.2% kuya ku-0.5% we-HPMC ngokususelwa esimweni esiphelele sikasimende nesihlabathi kunconywa.

I-HPMC iyisengezo esiguquguqukayo futhi esebenzayo esingathuthukisa kakhulu ukusebenza kwama-Plasters asuselwa kusawoti. Imvelaphi yayo yemvelo, ukuqina, kanye nobungani be-eco-ubungane kwenza kube inketho ekhangayo yosonkontileka, abakhi bezakhiwo, kanye nabanikazi bokwakha ababeka phambili izindlela zokwakha ezizinzile.
