Yintoni ukusetyenziswa kwe-hydroxypropyl methylcelgalose kwimichiza?

Hydroxypropyl methylcelculose (hpmc)Ngaba i-selly ye-ionic ye-ionic ye-ionic ye-ionic ye-ionsulose, eguqulwe ngemichiza kwiseli yendalo. Isakhiwo sayo siqulathe i-methyl kunye namaqela e-hydroxypropy, eyenza ukuba ibenako ukubenzela amanzi kakuhle, ukuqina, uzinzo kunye neepropathi zokwenza ifilimu. Ngenxa yezi propati ezizodwa, i-HPMC isetyenziswa ngokubanzi kwiindidi zemimandla, apho isicelo sayo kwizitolotho-mali sibaluleke kakhulu.

I-1. Ii-thickeiners kunye nabalawuli be-viscosity

Kwizitolo, enye yemisebenzi ephambili ye-HPMC injenge-thickener. Inganyusa kakhulu uVeksinity weZityholo, ukuphucula amava abo okusebenzisa kunye nokusebenza kwayo. Kwisicoci samanzi, ngakumbi isiciko esiphakamileyo, ukuqina kuyanceda ukulawula ulwelo lwesicoci, esenza uzinze ngakumbi ngexesha lokusetyenziswa kunye nokungaphantsi kwebhotile. Ukongeza, i-viscofity efanelekileyo ikwanceda ukunciphisa inkunkuma yokucoca kunye nokuphucula ububi bayo, ngokwenza oko kukwenza ukuba impembelelo ibaluleke kakhulu.

2. Ukuphuculwa kokuzinza kwe-surfcants

Izicoci zihlala ziqulathe ii-sundocapes, kwaye ukusebenza kwezi susfugants kunokuchaphazeleka zizinto zokusingqongileyo (njengamaqondo obushushu, i-PH, njl.njl.). Njengomgca omkhulu kunye ne-stabilizer, i-HPMC inokuphucula ukusebenza kwezinto zokucoca phantsi kweemeko ezahlukeneyo ngokuhlengahlengisa isisombululo kunye nokuzinza kwe-surfacapes. Kuyanceda ukunciphisa umgangatho wokungasebenzi kwe-foam kwaye igcine ukuqhutywa kweqhina lokucoca, ngakumbi ngexesha lokucoca apho i-foam ifumaneka khona ixesha elide.

3. Ukuphucula isiphumo sokucoca

Ukunamathela kwe-HPMC kuvumela izithako ezisebenzayo kwizinto zokucoca ukuba zilandele ngqo kumphezulu okanye amalaphu, ekwandiseni isiphumo sokucoca. Ingakumbi kwizitolo, i-HPMC inceda ekuphuculeni ukusasazeka kwamasuntswana amdaka ngamanzi, kubavumela ukuba basuswe ngempumelelo. Ukongeza, i-HPMC inokuphucula ukucoca ukusebenza ngokuthoba ukuhamba kwesicoci ukuze ihlale inxibelelana nobumdaka ixesha elide.

I-4. Ukuphucula uluhlobo lwe-skickents

Njengezinto ezifumaneka ngokwendalo, i-HPMC inee-biomities ezilungileyo kunye neepropathi ezinobulali. Ukongeza i-HPMC ukuya kwizinto zokucoca kunokuphucula ubulali bokunxibelelana kolusu kwaye unciphise ukucaphukisa ulusu. Ngakumbi iziqwengana zomntwana okanye izicoci ezenzelwe ulusu olunobuthathaka, i-HPMC inokudlala isiphumo sokukhulula, esenza isicoci esifanelekileyo sokusetyenziswa kwemeko apho kudibana khona nolusu ixesha elide.

I-5. Ukuqulunqwa kwe-membrane kunye nokukhuselwa

I-HPMCinamandla efilimu eqinileyo. Kwezinye iimveliso ze-orgent, i-HPMC inokwenza ifilimu ngexesha lenkqubo yokucoca ukubonelela ngokhuseleko olongezelelweyo. Umzekelo, kwezinye iziciko zempahla yokuhlamba iimpahla okanye izicoci, ifilimu ye-HPMC inokunceda ukukhusela indawo yendwangu okanye umonakalo, ngaloo ndlela yomonakalo, ngokwenza oko kubomi benkonzo yelaphu.

I-6. Ukuphucula iimvakalelo zokucoca

Ngenxa yokuziqengqeleka kwayo kunye nokuzimisela iipropathi, i-HPMC inokuphucula iimvakalelo zeziqwengana, zibethelela kwaye kube lula ukufaka isicelo. Umzekelo, kwizicoci zokutshiza ezisetyenziselwa ukucoca ikhitshi okanye igumbi lokuhlambela, i-HPMC ivumela ukucoceka ukuba ihlale phezu komhlaba ixesha elide, ivumela ukususwa okwaneleyo kwe-dill ngaphandle kokubaleka ngokulula.

I-7. Njengearhente yokukhutshwa kwezityalo

Kwezinye iimveliso ezizodwa ze-concegent, i-HPMC inokusetyenziswa njenge-arhente yokukhupha enzomali. Kuba i-HPMC iphosa kancinci, inokulibazisa ixesha lokukhululwa kwezinto ezisebenzayo kwizitolo, ukuqinisekisa ukuba izithako ezisebenzayo zinokuqhubeka nokusebenza ngexesha lokuhlambuluka, ngaloo ndlela baphucula isiphumo sokuhlamba.

8. Ukukhusela isisingqongileyo kunye nokuzinza

Njenge-polymer ethathwe kwizityalo zendalo, i-HPMC ineengenelo ezithile kukhuseleko lwendalo. Xa kuthelekiswa nezinye iikhemikhali zepetroleum-esekwe kwi-petroleum, i-HPMC ityhafile emanzini kwaye ayizukubangela umthwalo wexesha elide kwindalo esingqongileyo. Ngokuqhubela phambili kweekhonsepthi eziluhlaza kunye nendawo okusingqongileyo, abavelisi abaninzi abaphantsi sele beqalisile ukusebenzisa izixhobo zokwemvelo zendalo kunye ne-biodegraday. I-HPMC iye yaba lukhetho olufanelekileyo ngenxa ye-biodegradiance elungileyo.

Ukusetyenziswa kwehydroxypropyl methylcelceluploseKuluhlu lweewotshi kuboniswa ikakhulu kwiinkalo ezininzi ezinje ngokuzinza, ukuzinza, ukuphucula isiphumo sokucoca, ukuphucula ubuhlobo bobuntu, ukwenziwa kwefilimu, ukuphucula ukuchukumisa kunye nokukhululwa kwefilimu. Ukuhamba kwayo jikelele kwenza ukuba isetyenziswe ngokufuthi kwii-ofisi zoyikiso zanamhlanje, ngakumbi izicoci ezingamanzi, ukucoca izikhonkwane, iingcinezelo zonyango kunye nezinye iimveliso. Njengemfuno yabathengi yokwenzela ukunyuka kwendalo kunye nokuhlamba ngokufanelekileyo, i-HPMC, njengendawo yoyiso yendalo kunye nokuzinzileyo, inamathemba okusebenza kwishishini lokuthintela i-orgent.
