I-Intro ye-BEMIC ye-hec kunye ne-HPMC

Intshayelelo kwi-Hec (Hydroxyythy seluplose) kunye ne-HPMC (Hydroxypropyl Methylcelcelce
I-HydroxyEtheeteethy yeselutase (Hec) kunye ne-Hydroxypropyl Methylcelcelce (i-HPMC) ziindawo ezimbini ezibalulekileyo zeselselose ezisetyenziswa kakhulu kumashishini ahlukeneyo, kubandakanya amayeza, ukhathalelo lobuqu kunye nokutya. Zombini i-HEC kunye ne-HPMC zivela kwi-seluplose, oyena mntu ubalaseleyo we-polymer eninzi efumaneka kwiindonga zeseli ezityalo, ezaziwa ngamandla akhe kunye nezinto ezihambayo.

I-HYDROXYTYL ILANDILONE (Hec)
Isakhiwo sekhemikhali kunye neePropathi
I-HydroxyEtheetheetheetheetheetheetheetheetheetheetheetheetheetheethl yeselutase yi-polymer engeyiyo i-ionic, i-poly-allmer ye-injiki evela kwi-sellulose kwinkqubo ye-ethersise. Isakhiwo sayo semichiza siquka amaqela e-ithylene oxide (-C2C2H2H) eqhotyoshelwe kwi-selsulose i-sellose, ephucula ukubenzela amanzi kunye neepropathi ezinkulu. I-hec ivela njengemhlophe i-White-White-White-White-White-White-White-White-White-White-White-White-White-Wish-vissosity ephezulu kunye nokwenza ubuchule bokwenza ifilimu.

Inkqubo ye-Synthesis
I-synthesis ye-hec ibandakanya impendulo yesellulose ne-Ethylene Oxide Phantsi kweemeko zeAlkaline. Inkqubo iqhele ukubandakanya:

I-Alkalition: I-Seleculose inyangwa nge-alkali eyomeleleyo, enjengeSodium hydroxide, ukwenza i-alkali seluplose.
Isiseko: I-Ethylene oxide yongezwa kwi-alkali selsulose, ekhokelela ekusekweni kwe-hydroxyythyl sellise.
Ukungathathi cala kunye nokucoca: Umxube wokuphendula awunamacala kwaye uzihlanjululwe ukususa iimveliso, ukuvelisa imveliso yokugqibela yehek.

Izicelo
I-HEC isetyenziswa kumashishini ahlukeneyo ngenxa yepropathi eyahlukileyo:

Amayeza: Isetyenziswe njengearhente yokuthambisa, ifilimu - yangaphambili, kwaye imbizi kwi-gels egqogs, iikhrim, kunye ne-oyile.
Inkathalo yobuqu: ifunyenwe kwi-shampoos, ii-conditioners, i-outtions, kunye ne-soaps njenge-thiad kunye ne-mulsifier.
Iipeyinti kunye nepayini: iphucula i-viscosity, ukugcinwa kwamanzi, kunye neepropathi zokwenza ifilimu kwiipeyinti ezisekwe emanzini.
Ulwakhiwo: isebenza njenge-binder, i-thicker, kunye nearhente yokugcina amanzi kwisamente kunye ne-gypsim esekwe.
Izibonelelo

UHec unika izibonelelo ezininzi:

Imeko engeyiyo i-ionic: iyenza ihambelana noluhlu olubanzi lwee-Ionic kunye ne-UN-Ionic.
I-Solubaty yaManzi: inyibilikisa ngokulula kumanzi abandayo kwaye ashushu, enze izisombululo ezicacileyo.
Ukusebenza ngokuqinileyo: inika ulawulo oluhle kakhulu lwe-viscofity kwifomu ezahlukeneyo.
I-biomatisi-ikhuselekile ukuba isetyenziswe kwiimveliso zononophelo kunye nezomntu.

Hydroxypropyl methylcelculose (hpmc)
Isakhiwo sekhemikhali kunye neePropathi
I-Hydroxypropyl Methylcelcelcelose yenye ye-ionic selsulose ether, ephawuleka ngokufakwa endaweni yamaqela e-hydroxyl kwimolekyuli yeselselose (-Ch2chohch3) namaqela. Olu tshintsho lubonisa iipropathi zokungalawuleki ze-thermal kwaye zenze inyibilikisi kumanzi abandayo ashushu. I-HPMC iyafumaneka njengemhlophe ukuya kwi-powder emhlophe.

Inkqubo ye-Synthesis
Ukuveliswa kwe-HPMC kubandakanya inkqubo yokuthengiswa okufanayo:

I-Alkality: I-Seleculose ithwalwa nge-alkali eyomeleleyo ukwenza i-alkali sellulose.
I-EUTIORE: Ukudityaniswa kwe-methyl chloride kwaye i-proplene oxide yongezwa kwi-alkali seluplose, ekhokelela ekumiselweni kwe-hydroxlyproptl methylceluplose.
Ukungathathi cala kunye nokucoca: Umxube awuthathi cala, kwaye amanyathelo okucoca awenziwe ukufumana imveliso yokugqibela yeHPMC.

Izicelo
I-HPMC's uqoqosho ivumela ukuba isetyenziswe kwimimandla eyahlukeneyo:

Amayeza: Izenzo njengearhente elawulwayo, i-binder, kunye nempahla yokuhamba ngefilimu kwifom yetafile.
Umzi-mveliso wokutya: ukhonza njenge-thi choner, isitayile, kunye ne-mulssifier ngokutya okucwangcisiweyo.
Ulwakhiwo: Isetyenziswe njenge-gicker, iarhente yokugcina amanzi, kwaye inamathela kwizifakethi ezisekwe kwisamente kunye neeplate.
Inkathalo yobuqu: ifunyenwe kwi-toothpaste, i-shampoos, kunye ne-ivoting ngenxa yokuthambisa kwayo kunye nokuzinzisa iipropathi.

Izibonelelo
I-HPMC ithandwa ngenxa yezizathu ezininzi:

I-Thermal: Ibonisa ukuhlakulela ngenxa yokufudumeza, ingenelo kwizicelo ezithile zeyeza kunye nokutya.
Ukunyibilika: ukunyibilika kumanzi obandayo kunye namanzi ashushu, kuvumeleke ukuba busetyenziswe ngokuguquguqukayo kwiindawo ezahlukeneyo.
Isakhono sokwenza ifilimu: Yenza iifilimu ezomeleleyo, eziguquguqukayo, ilungele ukurhweba kunye nefomu yokukhupha.
Ukungabinamandla: Kukhuselekile ukuba basebenzise ukutya kunye nokusetyenziswa kwezicelo zamayeza, nge-biomatise egqwesileyo.

Thelekisa i-Hec kunye ne-HPMC

Iipropathi: Zombini i-HEC kunye ne-HPMC ayizizo i-ionic, i-polymers enyibilikayo yamanzi anezityholo ezifanelekileyo, ukwenza ifilimu, kunye nokuzinzisa iipropathi.
Izicelo: Zisetyenziswa kuluhlu olubanzi lwamashishini, kubandakanya amayeza, ukhathalelo lobuqu, nolwakhiwo.
Umahluko
Izinto zokuthambisa iikhemikhali: I-HEC iqulethe amaqela e-hydroxyyl, ngelixa i-HPMC ine-maquisxy kunye namaqela e-hydroxypropyl.
Iipropathi ze-Thermal: I-HPMC ibonisa ukungqubana kobushushu, ngokungafaniyo ne-hec, iyenza ilungele izicelo ezithile apho ukuhlanjwa kobushushu kuyingenelo.
Ukulwa: Ngelixa zombini zinyibilika emanzini, ubukho bamaqela e-hydroxypropy kwi-HPMC iphucula ukubethwa kwayo kwizinyibilikisi ze-organic.

I-HYDROXYETHyL seluplose (hec) kunye ne-Hydroxypropyl Methylcelcelce (i-HPMC) zizinto ezibalulekileyo zeselfowuni ngezicelo ezibanzi kumashishini ahlukeneyo ngenxa yepropathi yakhe eyahlukeneyo kunye nemisebenzi. I-HEC ixabisa ngokukhethekileyo kwi-viscofity ephezulu kunye nokuhambelana neezongezo ezahlukeneyo, ngelixa i-HPMC yahlulwe ziipropathi zayo zokungalawulekiyo kunye nokuluka kwabantu. Ukuqonda iipropathi, i-synthesis, kunye nokusetyenziswa kwezi polymers kuyanceda ukukhetha i-selsulose efanelekileyo yokufumana iimfuno ezithile zeshishini, ngaloo ndlela kuphuculwe ukusebenza kunye nomgangatho weemveliso zokuphela.
