Yintoni i-hydroxypropyl methylcelcelgalose ether mpmc ijongeka ngathi?

E-Putty, uGaste ongqengqelo lwe-gurpry esele i-Gypsim - i-HPMPROXYLYL MethylcelcelcelUlose I-Ether Orten idlala ikakhulu i-other yokugcina amanzi kunye nokuchasana ne-slickry. Izinto ezifana nobushushu bomoya, ubushushu kunye nesantya somoya esiya kuchaphazela inqanaba lamanzi e-bullty, udaka lwesamente kunye neGyppum. Ke ngoko, kumaxesha ahlukeneyo, kukho umahluko kumsebenzi wokugcinwa kwamanzi weemveliso ezinomgangatho ofanayo we-HPMC yongezwa. Kumsebenzi othile, umphumo wokugcinwa kwamanzi okutyibilika unokwanda ngokwanda okanye ukwehla kwe-HPMC yongezwa.

Ukugcinwa kwamanzi kwe-Methyl Seler I-Ether phantsi kweemeko zobushushu obuphezulu kubalulekile ukwahlula umgangatho we-methyl seteli. Iimveliso ezibalaseleyo ze-HPMC zinokusombulula ngokufanelekileyo ingxaki yokugcina amanzi phantsi kobushushu obuphezulu. Kumaxesha obushushu aphezulu, ngakumbi kwiindawo ezishushu nezomileyo kunye nolwakhiwo olucekeceke kunye ne-HET-DEARE Umgangatho ophezulu we-HPMC unokuguqula amanzi asimahla elunxwemeni ungene emanzini, ngaloo ndlela ulawula ukukhutshwa kwamanzi okubangelwa kukugcinwa kwamaqondo obushushu.

I-methyl ekumgangatho ophezulu ye-methyl inokuba ichithwe ngokufanelekileyo kwaye ichithwe ngokufanelekileyo kwizakhiwo ezisekwe kwi-Gyppum kunye ne-Gyppum esekwe kwi-Gyppum, kwaye zisonge onke amasuntswana aqinileyo, kwaye ize ifilimu emanzi, kwaye amanzi aya kukhutshwa ngokuthe ngcembe ixesha elide. Ukuphendula i-hydration kwenzeka, ngaloo ndlela iqinisekisa amandla ebhondi kunye namandla engcinezelo yezinto ezibonakalayo. Ke ngoko, kulwakhiwo oluphezulu lokwakha ihlobo, ukuze kufezekiswe ukusebenza kwamanzi, kuyafuneka ukongeza iimveliso ze-HPMC eziphezulu ze-HPMC kwifom yefomula. Ukuba i-HPMC ye-HPMC isetyenziswa, akwanelanga i-hyddition, incitshisiwe amandla, ukuqhekeza, kwaye i-voids iyakwenzeka ngenxa yokwaphuka kakhulu. Iingxaki ezisemgangathweni ezifana nemigqomo kunye nokutsala kwako ukunyusa ubunzima bokwakha abasebenzi. Njengoko amaqondo obushushu ahla, isixa se-HPMC songezwe sinokuncitshiswa ngokuthe ngcembe, kwaye kuya kufezekiswa.

Inkqubo yokuphendula ilawula ngokuchanekileyo ukuveliswa kwe-HPMC, kwaye ukufakelwa kwayo kugqityiwe kwaye ukufa kwalo kulungile kakhulu. Isisombululo sayo esicacileyo sicacile kwaye sicace, sineentsinga ezimbalwa zasimahla. Ukungqinelana nomgubo werabha, isamente, i-lime kunye nezinye izinto eziphambili zomelele, ezinokwenza izinto eziphambili zidlala eyona ntsebenzo iphambili. Nangona kunjalo, i-HPMC enendlela engalunganga ineentsinga ezininzi zasimahla, ukusasazwa okungalinganiyo kwezinto, ukugcinwa kwamanzi amahlwempu kunye nezinye iipropathi, ezikhokelela kwinani elikhulu lokuphuma kwamanzi kwimozulu yamanzi. Nangona kunjalo, obizwa ngokuba yi-HPMC (uhlobo lwe-contraund) ngesixa esikhulu sokungcola kunzima ukulungelelanisa, ngoko ke ukugcinwa kwamanzi kunye nezinye iipropathi zibi nangakumbi. Xa isetyenziswa i-HPMC engalunganga, iingxaki ezinje ngamandla e-slarry, ixesha elifutshane lokuvulwa, i-powd, eyakonyusa ubunzima besakhiwo.
