I-HPMC isetshenziswa embonini yamakhemikhali yezinto zokwakha

I-HPMC, eyaziwa nangokuthi i-hydroxypropyl methylcellulose, iyinhlanganisela yomndeni wama-cellulose ethers.Itholakala ku-cellulose, i-polymer yemvelo etholakala ezindongeni zamaseli ezitshalo.I-HPMC isetshenziswa kabanzi embonini yezokwakha ngenxa yezakhiwo zayo ezinemisebenzi eminingi.

I-HPMC ivamise ukusetshenziswa njenge-thickener, binder, i-film yangaphambili kanye ne-ejenti yokugcina amanzi ezintweni zokwakha ezifana nemikhiqizo eyenziwe usimende, izinto zokunamathisela zamathayela, amapulasi, amapulastele kanye nama-grouts.Ukwakheka kwayo kwamakhemikhali kuyivumela ukuthi imunce amanzi futhi yakhe into efana nejeli ethuthukisa ukusebenza, ukunamathela kanye nokumelana ne-sag yezinto zokwakha.

Nazi ezinye izakhiwo ezibalulekile kanye nokusetshenziswa kwe-HPMC embonini yezokwakha:

Ukugcinwa kwamanzi: I-HPMC imunca futhi igcine amanzi, ivimbele izinto ezisekelwe kusimende ukuthi zome ngokushesha.Lokhu kusiza ekunciphiseni ukuqhekeka, kuthuthukisa i-hydration futhi kuthuthukise amandla onke nokuqina kwemikhiqizo yokwakha.

Ukucutshungulwa okuthuthukisiwe: I-HPMC isebenza njengesiguquli se-rheology, ihlinzeka ngokucubungula okungcono kanye nokusetshenziswa okulula kwezinto zokwakha.Ithuthukisa ukusabalala nokumelana nokuwohloka kodaka namapulasi, okwenza kube lula ukuphatha nokufaka isicelo.

Ukunamathela nokubumbana: I-HPMC ithuthukisa ukunamathela phakathi kwezinto zokwakha ezahlukahlukene.Yandisa amandla esibopho sezinto ezinamathelayo zamathayela, amapulasi namapulasi, iqinisekisa ukunamathela okungcono kuma-substrates afana nokhonkolo, ukhuni namathayela.

I-Sag Resistance: I-HPMC yehlisa ukugoqa noma ukuwa kwezinto eziqondile ezifana nokunamathiswa kwethayela noma i-primer ngesikhathi sokufaka.Lokhu kusiza ukugcina ukujiya okufunayo futhi kuvimbele ukungqubuzana noma ukuconsa.

Ukwakhiwa Kwefilimu: Uma i-HPMC yoma, yakha ifilimu elincanyana, eliguquguqukayo, elisobala.Le filimu inganikeza ukumelana kwamanzi okungcono, ukumelana nesimo sezulu kanye nokuvikelwa kwendawo yezinto zokwakha ezisetshenzisiwe.
