Intshayelelo esisiseko ye-Hec kunye ne-HPMC

Hec (hydroxyyl seluplose) kunye ne-HPMC Ezi zixhobo zibaluleke kakhulu kwizinto ezisebenzayo ngenxa yepropathi yazo eyahlukileyo yomzimba kunye neekhemikhali.

I-1. Hec (Hydroxyylyl seluplose)

1.1 Ulwakhiwo olusisiseko kunye neepropathi
I-Hec yi-polymer ye-ionic engafakwanga i-Ionemer efunyenwe ngokutshintsha kweekhemikhali kweselutali yendalo. Isakhiwo sayo esisisiseko kukwazisa izinto ze-hydroxyteethl kwi-β-d-gucose skeleton of celsulose. Ngenxa ye-hydrophicicity yeqela le-hydroxytethyl kwisakhiwo sayo, i-hec inomoya olungileyo kunye neepropathi ezinkulu emanzini.

I-HEC ibonakalisa ukubambelela ngendlela elungileyo, ukwenza ifilimu kunye nezinto zexabiso lefilimu, kwaye kukwayicime-kunye ne-alkali-enganyangekiyo kwaye ineendawo ezintle. Ezi ndawo zenza ukuba i-ticker esebenzayo kakhulu, i-stiblizer kunye nearhente yefilimu yefilimu kwiinkqubo ezikhukuzayo. Ukongeza, isisombululo se-hec sineThiXotPopy, enokubonisa i-viscosity ephezulu phantsi kwamandla asezantsi asezantsi, kwaye i-viscosity ihla ngokukhawuleza phantsi komkhosi ophezulu. Olu phawu lwenza ukuba libe nexabiso elifanelekileyo lokufaka isicelo kunyango oluhlukeneyo lwamanzi.

1.2 Inkqubo yokulungiselela
I-hec ilungiselelwe ikakhulu yi-etheriyation yokuphendula ye-seluplose yendalo. Izinto ezixhaswayo ezisetyenziswayo ziquka imithombo yeselfowuni efana nekotoni kunye neenkuni, ezisabela kwi-i-ithoylene oxide emva kokufumana i-hydroxyEse. Ngexesha lenkqubo yonke yokuphendula, ulawulo lweemeko zokuphendula (ezinje ngamaqondo obushushu, ixabiso le-pH kunye nexesha) linempembelelo ebalulekileyo kwinqanaba lokufakwa endaweni, ukulingana kunye nokubonisa imveliso yokugqibela.

1.3 amasimi esetyenziswayo
I-HEC isetyenziswe ngokubanzi kwizinto zokwakha, iingubo, iichemicals zemihla ngemihla, amayeza kunye nokutya. Kwizinto zokwakha, i-HEC isetyenziswe ngokubanzi ngodaka lwesamente kunye ne-gypsim njenge-tickener esebenzayo kunye nokuzinzisa ukuphucula imisebenzi yawo kunye neepropathi ezichasene noko. Kwishishini lezixhobo, i-HEC lingasetyenziswa njenge-gickener kunye ne-geoology modifiers yamandla asekwe emanzini ukuphucula umlinganiso kunye nokugungqa kwengubo. Kwimichiza yemihla ngemihla efana ne-shampoo kunye ne-wittizer yesandla, i-HEC isetyenziswa njenge-thickener kunye ne-moicurizer ukunika imveliso imvakalelo elungileyo kwaye uzinzo. Ukongeza, kumashishini okutya amayeza, i-HEC isetyenziswa njenge-binder yeetafile, ifilimu yangaphambili yecapsule, kunye ne-thi chicker kunye ne-stickener yokutya ngenxa yetyhuzulane yayo elungileyo kunye netyhefu esezantsi.

I-2. I-HPMC (Hydroxypropyl Methylcelcelceluplose)

2.1 Isakhiwo esisisiseko kunye neepropathi
I-HPMC yi-ionic ye-ionsulose ether efunyenwe ngokwazisa amaqela e-hydroxypropy kunye namaqela e-mayipsy kwi-selsuloton. Ifana ne-HEC, i-HPMC inomhlaba olungileyo wamanzi, ukuqina, ukwenziwa kweefilimu kunye ne-biomatise. Ngenxa yendlela ye-fhydroxypropy yesakhiwo sayo, i-HPMC ayinalo kuphela i-solity elungileyo emanzini, kodwa ikwabonisa imisebenzi eqinileyo yomhlaba kunye nemilinganiselo yokumiswa.

Uhlobo lwe-viscosity yesisombululo se-HPMC uchaphazeleka kakhulu kubushushu. Kuluhlu oluthile lobushushu, ukugcinwa kwesisombululo se-HPMC sehlisa ngokukhulisa ubushushu obukhulayo. Ukongeza, i-HPMC ikwanezinto ezilungileyo zejeli. Xa ubushushu besicombu bugqitha ixabiso elithile, iya kwenziwa ijeli. Le ndawo inexabiso elikhethekileyo lesicelo kwimimandla yokutya neyeza.

Inkqubo yokulungiselela
Ukulungiswa kwe-HPMC kuyafana ne-hec, kwaye kukwenziwa ngenkqubo yokuphendula kwe-etherUlose. Ngokwesiqhelo, i-selupese inikezela nge-propylene oxide kunye ne-methyl chloride phantsi kweemeko ze-alkaline yokwazisa amaqela e-hydroxypropy kunye ne-mayiptions, ngokwahlukeneyo. Iipropathi ze-HPMC (ezinjenge-viscofity, isolity kunye neqondo lokushisa le-gel) linokulawulwa ngokuchanekileyo ngokuhlengahlengiswa kwenqanaba lokufaka endaweni kunye neemeko zokuphendula.

2.3 Amasimi esetyenziswayo
I-HPMC inoluhlu olubanzi lwezicelo kwicandelo lolwakhiwo, amayeza, ukutya kunye neekhemikhali zemihla ngemihla. Kwizinto zokwakha, i-HPMC isetyenziswe ngokubanzi kwi-creating yesamente kunye neemveliso ze-gypsim njenge-gickerer, irefeti yenkcenkceshelo kunye ne-Binder kunye ne-Binder yokuphucula ukusebenza kunye nokuqina kwento leyo. Kwintsimi yamayeza, i-HPMC isetyenziswa njengearhente yokukhutshwa elawulwayo, i-onhees kunye ne-capsule yokuhamba kweetafile, ezinokulawula ngokufanelekileyo iziyobisi kunye nokuphucula uzinzo lwamachiza. Kwishishini lokutya, i-HPMC isetyenziswe ngokubanzi njenge-thi checker kunye ne-emulsifier kwiimpahla ezibhakiweyo, iimveliso zobisi kunye neendlela zokuphucula ukuthungwa kunye nokungcamla iimveliso. Ukongeza, i-HPMC isetyenziswa ngokubanzi kwiikhemikhali zemihla ngemihla njengeShampoo, i-condioner, icocekile ubuso, njl njl.

Njenge-SeleIases ezimbini zeselsulose, i-HEC kunye ne-HPMC idlala indima ephambili kumashishini amaninzi. I-HEC isetyenziswa ngokubanzi ekwakhiweni, iingubo, iichemicals zemihla ngemihla kunye namayeza emihlatho ngenxa yokufowuna okugqwesileyo, ukwenza ifilimu kunye ne-biomatise. I-HPMC, kwelinye icala, idlala indima ebalulekileyo ekwakhiweni, amayeza kunye namashishini okutya ngenxa yeepropathi zayo ezihlukileyo kunye neendawo ezisetyenziswa ngokubanzi. Ngokuqhubela phambili kwetekhnoloji, inkqubo yokulungiselela kunye neendawo zokufunda kwezi zinto zimbini ziya kuqhubeka nokwandisa, ukuzisa amathuba amaninzi okuphuhlisa amashishini ahambelana nemizi mveliso enxulumene noko.
