Ukusetyenziswa kwe-hydroxypropyl methylcellulose kumdaka

1. Ukugcinwa kwamanzi

IHydroxypropyl methylcellulose yokwakha ikhusela ukufuma ekungeneni eludongeni.Isixa esifanelekileyo samanzi sihlala kwidaka, ukuze isamente ibe nexesha elide lokumanzisa.Ukugcinwa kwamanzi kuhambelana ne-viscosity yesisombululo se-cellulose ether kumdaka.Ukuphakama kwe-viscosity, ngcono ukugcinwa kwamanzi.Emva kokuba iimolekyuli zamanzi zanda, ukugcinwa kwamanzi kunciphisa.Ngenxa yokuba umlinganiselo ofanayo wokwakhiwa kwesisombululo se-hydroxypropyl methylcellulose, ukwanda komthamo wamanzi kuthetha ukuhla kwe-viscosity.Ukuphuculwa kokugcinwa kwamanzi kuya kukhokelela ekwandisweni kwexesha lokulungisa udaka olwakhiwayo.

2. Ukuphucula ukwakheka

Ukusetyenziswa kwe-hydroxypropyl methylcellulose HPMC kunokuphucula ukwakhiwa kodaka, ukwenza imveliso yodaka ibe nokusebenza kakuhle kokusasaza, ukunciphisa ukunamathela kwizixhobo zokusebenza, ukwenza ukwakhiwa kube lula, kunye nokunciphisa ukunyanzeliswa ngokomzimba kwabasebenzi.

3. Umxholo webhabhula

Umxholo we-bubble womoya ophezulu uphumela kwisivuno esingcono sodaka kunye nokusebenza, ukunciphisa ukubunjwa kokuqhekeka.Kwakhona kunciphisa ixabiso lokuqina, okubangelwa "i-liquefaction" isenzeko.Isiqulatho seqamza lomoya sikholisa ukuxhomekeka kwixesha lokuzamisa.Iimveliso zisetyenziselwa kakhulu ukuphucula ukusebenza kwezinto zokwakha ze-hydraulic, ezifana ne-samente kunye ne-gypsum.Kwizidumbu ezisekelwe kwisamente, kuphucula ukugcinwa kwamanzi, kwandisa ukulungiswa kunye namaxesha avulekileyo, kunye nokunciphisa ukuthoba.

4. Anti-sagging

Udaka oluqinileyo olumelana ne-sag luthetha ukuba xa lugalelwe kumaleko ashinyeneyo akukho ngozi yokuhexa okanye ukuqukuqela okuhla.Ukumelana ne-Sag kunokuphuculwa ngolwakhiwo oluthile lwe-hydroxypropyl methylcellulose.Ngokukodwa i-hydroxypropyl methylcellulose esanda kuphuhliswa yokwakhiwa inokubonelela ngeempawu ezingcono zokuchasana nodaka.

5. Ukukwazi ukumanzisa

Iimveliso ezifanelekileyo ze-cellulose ether zinokuphucula i-viscosity yodaka ngelixa uqinisekisa umsebenzi womphezulu kunye nokunamathela okumanzi kodaka, okwenza ukuba udaka lube nokusebenza kakuhle ekumanziseni i-substrate, nokuba isetyenziswe kwi-EPS okanye i-XPS, njl. akukho-curling kunye ne-non-wetting phenomenon kwisiseko esikhethekileyo somgangatho.
