Zithini iindidi ezahlukeneyo ze-hydroxyEsethl seluplose (hec)?

I-HydroxyEtheetheetheetheetheetheetheethl seluplose (hec) i-polymer ye-polymer ye-polymer efunyenwe ngokuguqulwa kwemichiza yeselutase yendalo. Isetyenziswa ngokubanzi kwi-cayishini, iikhemikhali zemihla ngemihla, izinto zokwakha kunye nezinye iinkalo. Iindidi ezahlukeneyo ze-hec zihlelwe ikakhulu ziiparamitha ezinjengesiqinisekiso sokufakwa endaweni (DS), endaweni ye-molar

1. Ukuhlelwa ngumgangatho wokufaka

Inqanaba lokufakwa endaweni (DS) libhekisa kwinani eliphakathi lamaqela e-hydroxyythy kwiyunithi nganye yeglucose. Utshintsho kwi-DS luya kuchaphazela ukunyibilisela, i-viscosity kunye neendawo zesicelo se-hec.
Inqanaba eliphantsi le-HEC ye-HEC: DS ingaphantsi kwe-1.0. Inqanaba eliphantsi le-HEC line-smollity eliphantsi kwaye ihlala isetyenziswa kwiindawo ezifuna inqanaba elithile lokunganyangeki kwamanzi, njengezinto zokwakha kunye neengubo ezithile.
Inqanaba eliphakathi le-HEC: DS iphakathi kwe-1.0 ne-2.0. Olu hlobo lwe-HEC lunezoluleko oluhle lwamanzi kunye noku-viscofity ephezulu, kwaye ihlala isetyenziswa kwiimveliso zemichiza zemidlalo yemihla ngemihla (njengokucoca kunye ne-cosmetics), iingubo kunye ne-eulssions.
Inqanaba eliphezulu le-HEC: DS ingaphezulu kwe-2.0. Olu hlobo lwe-HEC lune-solity ephezulu kwaye ihlala isetyenziswa kwizicelo ezifuna ukungafihli nto kunye noku-viscofity ephezulu, njengamantshontsho ngamehlo, njl.

I-2. Ukwahlulahlulwa kwe-molar
Ukufakwa kwe-Molar Ixabiso eliphakamileyo le-MS, ngcono ukulingana kwamanzi kunye nenqanaba lokuchitha i-hec ngokubanzi.
I-hec ye-hec ephantsi ye-HOAR: I-Nks ingaphantsi kwe-1. Olu hlobo lwe-HEC lunenqanaba lokuchithwa kancinci kwaye kunokufuna amaqondo obushushu aphezulu okanye amaxesha amade avuselelayo. Ilungele ukusetyenziswa kwezicelo ezifuna ukuhlangulwa okanye ukukhutshwa okulawulwa.
I-Head Spotitations ye-HALLA: I-NS iphakathi kwe-1 ne-2. Inexabiso lokuchithwa eliphakathi kwaye lisetyenziswe ngokubanzi kwiikhemikhali zemihla ngemihla, ikhredithi, kunye nolwakhiwo.
I-hec yokufakwa e-IPOL ye-WOAL: I-MS inkulu kune-2. Inomqondo onqabileyo wokuncitshiswa kunye nokusonjululwa okugqwesileyo, kwaye ilungele izisombululo ezifuna ukutshabalalisa okanye ezibonakalayo, ezilungiselela ezonyango.

I-3. Ukwahlula-hlula nguVolcosity
I-viscosity ye-hec yisalathiso esibalulekileyo solwelo lwayo kwisisombululo, idla ngokusekwe kwi-dilution (uxinzelelo) lesisombululo kunye nemilinganiselo yemilinganiselo (njengemilinganiselo ye-Shear).
I-hec ye-hec ephantsi: i-viscosity kwi-1% yesisombululo ingaphantsi kwe-1000 Mparo. I-hec ephantsi ye-Vickosity ilungele ukusetyenziswa njengearhente yolawulo lwe-gemology, isisasazi kunye neoyile, kwaye isetyenziswa ngokubanzi kwiimveliso zemichiza zemihla ngemihla, ishishini lokutya, kunye namalungiselelo athile okwenza amayeza.
I-Vidasity Hec: ​​I-viscofity kwi-1% yesisombululo siphakathi kwe-1000 ne-4000 MPAFS. I-Vidasity Vickosity Hec isetyenziswa ngokubanzi kwi-cares, imihlambi, i-interks zokushicilela, kunye nemizi-mveliso yokwakha, ukubonelela ngeziphumo ezihle zolawulo olufanelekileyo kunye nolawulo lwe-gemology.
I-Viscosity Heccofity Hec: ​​I-viscosity kwisisombululo se-1% ingaphezulu kwe-4000 Mparo. I-Vicofity ye-Vicofity isetyenziswa ikakhulu njengendawo enkulu kwaye imbi, ilungele imihlaba efuna uVelweni oluphezulu kunye nokungafihli nto, njengokuchonga okuphezulu, kunye nezicelo ezithile zophuhliso.

I-4. Ukwahlulahlulwa ngefom yemveliso
I-hec inokuhlelwa ngokwendlela yayo yomzimba, ehlala ichaphazela ukusetyenziswa kwayo nokusingatha.
I-HOCDEDRED HEC: Olona hlobo luqhelekileyo, kulula ukuhambisa kunye nokugcina. Isetyenziswe kwizicelo ezininzi zemizi mveliso kunye nemidlalo yemihla ngemihla, kufuneka idityaniswe emanzini ukwenza isisombululo.
I-Granular Hec: ​​I-hec ye-Granular ilula ukuyiphatha kwaye inyibilike kune-hec efihlakeleyo, inciphisa iingxaki zothuli kwaye ilungele ukuveliswa kwemveliso enkulu.
Isisombululo-Uhlobo lohlobo lwe-hec: kwezinye izicelo eziphezulu, i-hec inokubonelelwa ngqo kwifom yesisombululo, elungele ukusetyenziswa ngqo nokunciphisa ixesha lokuthambisa, njengeemveliso ze-cosmetics kunye neemveliso zamayeza.

I-5. Umsebenzi we-hec osebenzayo
Kukwakhona nezinye iihecs eziye zalungiswa rhoqo okanye zinyangwe ngokwasemzimbeni ukuze zifezekise iimfuno zezicelo ezithile.
Ukuwela i-HEC: Ukuchasana kwamanzi kunye neepropathi zoomatshini kuphuculwe ngokuqinisa imichiza, kwaye kufanelekile ukuba izihlandlo ezifuna amandla aphezulu kunye nokuqina.
Modified HEC: Further modification (such as carboxymethylation, phosphorylation, etc.) is made on the basis of HEC to give it more functions, such as improved antibacterial properties, heat resistance or adhesion.
I-HEC exubeneyo: Idityaniswe nezinye ii-thi chunga okanye izinto ezisebenzayo ukomeleza intsebenzo yayo ngokubanzi, enjengokusetyenziswa kwee-trickeners ezihlanganisiweyo kwingubo.

Njengezinto ezibalulekileyo ezinyibilikayo zamanzi, iintlobo ezahlukeneyo ze-hydroxytethl seluplose (hec) zilungelelanise iimfuno ezahlukeneyo zesicelo ngeendlela zokufaka endaweni yokufakelwa, i-molar Ukuqonda ezi zinto zikhefu kunceda ukukhetha iimveliso ezifanelekileyo ze-Hec kwizicelo ezisebenzayo ukufumana eyona ntsebenzo kunye nefuthe. Nokuba kusekwe kwiikhemikhali zemihla ngemihla, izinto zokwakha, iingubo okanye amayeza, i-HEC isetyenziswa ngokubanzi kwipropathi yayo elungileyo, yokunyathela ifilimu.
