I-Cellulose HPMC, okanye i-hydroxypropyl methylcellulose, isetyenziswa ngokubanzi kwishishini lokugquma.Yinto engeyotyhefu, esebenza kakhulu kwaye inezinto ezininzi.I-HPMC ithathwa kwimicu yezityalo kwaye inyibilika lula emanzini.Inoluhlu olubanzi lwezicelo kwizixhobo zokwakha, ukwakheka kweengubo, ukunamathela kunye namanye amashishini ahambelanayo.
I-Cellulose HPMC iza kwiindidi ezimbini: ngoko nangoko kunye nokungakhawuleziyo.Ngamnye uneempawu ezikhethekileyo kwaye ufanelekile kwizicelo ezithile.Kweli nqaku, siza kuphonononga umahluko phakathi kwe-HPMC ye-cellulose ekhawulezileyo kunye ne-non-instant cellulose HPMC yokwaleka.
Instant Cellulose HPMC
Instant Cellulose HPMC luhlobo lwe HPMC enyibilikayo emanzini abandayo.Inexesha elikhawulezayo lokuchithwa, okuthetha ukuba linokusasazeka emanzini kwimizuzwana.I-HPMC ekhawulezileyo iqhele ukusetyenziswa kwiingubo ezifuna ukujiya ngokukhawuleza, okufana nokunqunyanyiswa, i-emulsions kunye nezicelo eziphezulu ze-viscosity.
Enye yeenzuzo eziphambili zeselulosi ekhawulezileyo HPMC yi-dispersibility yayo ebalaseleyo.Inyibilika emanzini ngaphandle kwamaqhuma okanye amaqhuma.Olu phawu lwenza ukuba lulungele ukusetyenziswa kwiifomyulo eziphezulu eziqinileyo njengoko ziqinisekisa i-viscosity ehambelanayo kwibhetshi.
Instant cellulose HPMC ikwasebenza kakuhle kakhulu, ibonelela ngeempawu ezigqwesileyo zokujiya kwiindawo ezisezantsi.Ayichaphazeli umbala okanye i-gloss yepeyinti, iyenza ifaneleke ukuqulunqwa okuninzi.Ukongeza, i-HPMC ekhawulezileyo iyaxhathisa kwi-enzymes, i-acids, kunye ne-alkalis, nto leyo ethetha ukuba inozinzo oluhle lweekhemikhali.
Iselulosi engekho ngoko nangoko HPMC
Kwelinye icala, i-HPMC engeyiyo i-cellulose ayinyibiliki emanzini abandayo kwaye ifuna ukufudumeza ukunyibilika.Kuthatha ixesha elide ukunyibilika kuneselulosi ekhawulezileyo ye-HPMC kwaye ifuna amaqondo obushushu aphezulu ukuba isasazeke ngokupheleleyo.Ii-HPMC ezingezizo ezomzuzwana zidla ngokusetyenziswa kwiingubo apho ukujiya okucothayo kunye okucothayo kunqweneleka.
Enye yeenzuzo eziphambili ze-HPMC ze-cellulose ezingeyo-ngoko nangoko kukukwazi ukubonelela ngesiphumo sokutyeba ngokuthe ngcembe ngokuhamba kwexesha.Ayibangeli utshintsho ngokukhawuleza kwi-viscosity enokuthi ichaphazele umgangatho jikelele wepeyinti.Non-ngoko nangoko HPMC uneempawu rheological ebalaseleyo kwaye ilungele ukusetyenziswa yokwaleka apho iqondo eliphezulu lolawulo phezu flow kunye nomgangatho imveliso kufuneka.
I-HPMC ye-cellulose engekho ngoko nangoko ineempawu ezibalaseleyo zokwenza ifilimu, oku kuthetha ukuba inceda ukuphucula ukuqina kweengubo.Inokumelana nemozulu, imitha ye-UV kunye nezinye izinto zokusingqongileyo, iqinisekisa ukuba i-coating ihlala injalo ngokuhamba kwexesha.Ukongeza, i-HPMC engekho ngoko nangoko inomphezulu wokuncamathelisa kakuhle, othintela ukwambathisa ekuxovuleni okanye ukukrazula.
Zombini i-cellulose ekhawulezileyo kunye ne-non-in-instant HPMC ineepropati ezizodwa kunye neenzuzo ezenza ukuba zilungele izicelo ezithile kwishishini lokugquma.Instant cellulosic HPMC ilungele ukutyabeka ezifuna ukujiya ngokukhawuleza, lo gama non-ngoko nangoko HPMC yeyona ilungileyo izicelo ezifuna ukujiya kancinane nangokucothayo.
Nokuba luhlobo luni lweselulosi HPMC esetyenzisiweyo, izibonelelo zale nto iguquguqukayo ayinakuphikiswa.Yongeza ixabiso kwiingubo ngokuphucula ukuqina, ukulinganisa, ukunamathela kunye nokuqina.Ngaphezu koko, ayinayo ityhefu kwaye ayinabungozi kokusingqongileyo, iyenza ibe lolona khetho lubalaseleyo kwimixube ejolise ekunciphiseni ifuthe labo lokusingqongileyo.
I-Cellulose HPMC yinto esebenza kakhulu kwaye iguquguqukayo enokuthi izise iinzuzo ezibalulekileyo kwiingubo.Ukusetyenziswa kwayo kubalulekile ekuphuculeni umgangatho wepeyinti, ekugqibeleni ichaphazela ukwaneliseka ngokubanzi komsebenzisi wokugqibela.
