Ungayikhetha njani i-viscosity ye-HPMC xa uvelisa udaka lomgubo owomileyo?

Xa uvelisa i-powty powder kunye nodaka olosiweyo, ukhetha i-viscofity elungileyo ye-hydroxypropyl methylcelsulose (i-HPMC) ibalulekile ekusebenzeni kwemveliso. Njengemichiza ebalulekileyo yekhemikhali, i-HPMC inemisebenzi yokutyibilika, ukugcinwa kwamanzi, kunye nokuzinza.

1. Indima ye-HPMC kwi-putble powder kunye nodaka olosiweyo

Ukutyibilika: I-HPMC inokwandisa ukungqinelana komgubo we-poty kunye nodaka olosiweyo ukuze kuqinisekiswe ukusebenza kunye nokunamathela ngexesha lokwakha.
Ukugcinwa kwamanzi: i-HPMC inyanzele ukugcinwa kwamanzi okugqwesileyo kwaye inokuphucula ukuphulukana namanzi, ngaloo ndlela kudlulisa i-powty Powder kunye nodaka olwalukileyo, oluyingenelo lokwenza imveliso yokugqibela.
Uzinzo: I-HPMC inokuthintela ukunyanzelwa kunye nokwahlulahlula udaka olosiweyo kunye ne-poced powder ngexesha lokugcina kunye nokugcina ukufana komxube.

2. IZINTO EKUFUMANELEKILEYO UKUKHANGELA UKUKHETHA KWE-HPMC Viscofity

Xa ukhetha i-vickosity ye-HPMC, ezi zinto ziphambili zilandelayo kufuneka ziqwalaselwe:
Uhlobo lwemveliso kunye nokusetyenziswa: I-popler yomgubo kunye nodaka olwalumisiweyo lunezinto ezahlukeneyo kwaye ufuna ukundwendwela okwahlukileyo. Umzekelo, i-pollty powty powder ifuna ukumiswa okuphezulu kokunqunyanyiswa okungcono, ngelixa udaka lomgangatho unokufuna ukubonwa okuncinci kulwelo olungcono.
Indlela yokwakha: Iindlela ezahlukeneyo zokwakha zineemfuno ezahlukeneyo zokubonisa i-HPMC. Isicelo sesikhokelo ngokubanzi sifuna ukumiswa okuphezulu, ngelixa ukutshiza koomatshini kufuna i-viscofity nephantsi ukuqinisekisa ukwakhiwa okubonakalayo.
Iimeko zendalo esingqongileyo: Amaqondo obushushu anobushushu kunye nokufuma akuchaphazeli ukusebenza kwe-HPMC. Phantsi kweemeko zobushushu obuphezulu, ukukhetha i-HPMC ephezulu ye-HPMC inokulawula ilahleko yamanzi, ngelixa kumgangatho ophezulu wokufuma, i-HPMC esezantsi inokuphucula ukwakhiwa.
Inkqubo yokwenziwa: Ezinye izithako ezibandakanyiweyo kwifomula ye-podty powder kunye nodaka olomileyo luya kuchaphazela ukhetho lwe-HPMC. Umzekelo, ubukho bezinye izinto ezinkulu, iifilimu okanye ii-songers zinokufuna i-HPMC ukuze ilungiswe ukuze ifezekise ibhalansi.

I-3. Iikhrayitheriya zokukhetha i-HPMC Viscofity
Uhlobo lwe-HPMC luboniswa ngokubanzi kwi-MPAFS (imizuzwana)). Oku kulandelayo ziindlela zokukhetha i-HPMC zokuKhetha:

I-POTTY POLDER:
I-Wall Poby Powder: I-HPMC ene-150,000 yee-MPAF ifanelekile ekusebenzeni lezandla kunye neemfuno eziphezulu zokumiswa.
Umgangatho we-poty powty powder: i-HPMC ene-50 000 000 000 ilungele ngakumbi ukuqinisekisa ukuba ulwelo kunye nokusasazeka.

Udaka olwamileyo:
Umdaka wamanzi: I-HPMC ene-30,000-60 000 mpasi ilungele ukuphucula ukugcinwa kwamanzi kunye nokusebenza ngokwakhiwa.
Ukufakelwa kwe-PATSTER: I-HPMC ene-75,000 yeeMpando i-Mpando yongeza ukungangqinelani kwaye ilungele isicelo sencwadana.
I-Tile Adhesive: I-HPMC ene-100,000 yee-2000,000 ilungele ii-tilesthes ezifuna amandla aphezulu akwandisiweyo.
Injongo ekhethekileyo yodaka: ezinje ngodaka lokuziqokelela kunye nokulungisa udaka, i-HPMC ephantsi (i-HPMC ephantsi (20,000) i-MPAFS ye-MPAFRO) idla ngokusetyenziswa ngokusebenza kakuhle nokuzibandakanya.

Iv. Iingcebiso ezisebenzayo ze-HPMC Viscofity

Kwinkqubo yemveliso yokwenyani, ezi ngcebiso zilandelayo kufuneka zilandelwe xa khetha i-HPMC Viscofity:
Ukuqinisekiswa kovavanyo: Ngaphambi kokuveliswa kobuninzi, iimvavanyo ezincinci zenziwa ukuqinisekisa isiphumo se-viscofity ye-HPMC kwimveliso yemveliso. Kubandakanya iparamitha yentsebenzo efana nokwakha, ukugcinwa kwamanzi, isantya esiqatha.
Iingcebiso zabathengisi: nxibelelana nenkxaso yezobuchwephesha bomthengisi we-HPMC ngolwazi oluneenkcukacha kunye neengcebiso malunga nemveliso. Bahlala bekwazi ukubonelela ngezimpulu ze-HPMC ngokuVamefis ezahlukeneyo zovavanyo.
Uhlengahlengiso kunye nohlengahlengiso: Ngokwesiphumo sokusetyenziswa kwenyani, i-viscosity ye-HPMC ihlengahlengiselwe ukwenza umsebenzi wemveliso. Ngexesha lenkqubo yokwenza isicelo, ukhetho lwe-HPMC luhlengahlengiswa ngexesha luqwalasela utshintsho ekuqulunqweni nasekutshintweni kokusingqongileyo.

V. Uvavanyo kunye noLawulo loMgangatho we-HPMC Viscosity

Emva kokukhetha i-HPMC ngohlobo olufanelekileyo, ulawulo lomgangatho kukwayeyona nto iphambili:
Ukuzimisela kwe-viscosity: Vavanya i-viscofity yesisombululo se-HPMC usebenzisa i-visment esemgangathweni (enjengomntu ofana ne-visment) ukuqinisekisa ukuba ifezekisa iimfuno zenkcazo.
Uvavanyo lokugcina amanzi: Vavanya ukugcinwa kwamanzi ngomgubo obenziweyo kunye nodaka olwalume ukuze kuqinisekiswe ukuba imisebenzi yokugcina amanzi ye-HPMC ihlangabezana nemigangatho elindelweyo.
Uvavanyo lokwakha: Vavanya ukuphucula imveliso yokwakhiwa kwezenyani ukuqinisekisa ukuba iziphumo zokoyikiswa kwe-HPMC azichaphazeli ukungasebenzi.

Ukukhetha i-HPMC ngohlobo olufanelekileyo kubalulekile ekuvelisweni komgubo osebenza kakhulu kunye nodaka olosiweyo. Kuxhomekeka kwimveliso yemveliso, indlela yokwakha, iimeko zokusingqongileyo kunye nenkqubo yokuqulunqwa, i-HPMC ene-viscofisies eyahlukileyo kufuneka ikhethwe ukuba ifezekise iimfuno ezithile. Ngokungqinisisa uvavanyo, izindululo zabathengisi, uhlengahlengiso lohlengahlengiso kunye nolawulo oluphambili, lunokuqinisekiswa ukuba imveliso yokugqibela inesiqhelo, ukugcinwa kwamanzi kunye nokuzinza komhlaba, ngaloo ndlela kuphucule ukhuphiswano lwemveliso.
