Yintoni umahluko phakathi kwe-HPMC ngaphandle kwe-S?

I-HydroxyPOpyl Methylcelcelsulose (HPMC) yindawo yemichiza esetyenziswa kakhulu kwindawo yamayeza, ukutya, i-cosmetic kunye namashishini okwakha. Yenziwe ikakhulu nge-methylcelgalose kunye ne-hydroxypropy yeseluplose ngokusebenzisa ukuphendula kweekhemikhali, kwaye inayo imisebenzi yokuthambisa, iziseko, ukwenziwa kwefilimu kunye nokuthambisa.

Iimpawu ezisisiseko ze-HPMC
Isakhiwo sekhemikhali: Isakhiwo sekhemikhali se-HPMC siqulethe izinto ezimbini, i-methyl kunye ne-hydroxypropy, eqhagamshelwe kwimolekyuli yesellulose ngokuphendula. Ubukho be-methyl kunye namaqela e-hydroxypropy yeyokwenza ukuba ibenomoya ofanelekileyo kunye nomsebenzi womhlaba.

Ukuluka: I-HPMC inokunyibilikisa ngokukhawuleza emanzini ebandayo ukwenza isisombululo esibonakalayo okanye kancinci isisombululo, kodwa i-insulable emanzini ashushu. Le propati yenza ukuba iluncedo kwizicelo ezininzi, ezinje nge-arhente yokukhutshwa kunye ne-tickener kumalungiselelo amachiza.

I-Viskosity: Uhlobo lwesisombululo se-HPMC sichaphazeleka liqondo lokushisa, uxinzelelo kunye nesidanga sokufaka endaweni. Iimveliso ze-HPMC ezinamanqanaba ahlukeneyo okufaka umntu zinokubonelela ngeendlela ezahlukeneyo zobushushu ukuze zifezekise iimfuno zezicelo ezahlukeneyo.

Umahluko phakathi kwe-HPMC ye-HPMC kunye ne-HPMC eqhelekileyo
Kwezinye izicelo, ngakumbi kumashishini okutya kunye nokutya, ubunyulu kunye nemveliso yemveliso ziyimpawu ezibaluleke kakhulu. I-Sulfur (s) inokuthi ithathwe njengenqaba kwezinye iimeko, ke ezinye iimeko zesicelo zifuna ukusetyenziswa kwe-S-free hpmc.

Ukucoceka okuphezulu: I-HPMC i-HPMC iphantsi kwenqanaba eliqingqiweyo elingaphezulu ngexesha lenkqubo yokususa i-sulfure kunye nemilinganiselo yayo. Le hpmmc ephezulu ye-HPMC ilungele ukusetyenziswa kwezicelo ezinovelwano ngokungcola, ezinjengamalungiselelo amayeza amayeza aphezulu kunye ne-cosmetics ephezulu.

Uzinzo olunamandla: kuba i-sulfuur inokuthatha inxaxheba kwi-ReOXPOLS ephindaphindiweyo phantsi kweemeko ezithile, kukhokelela kutshintsho okanye ukonakala kwimveliso yemveliso. I-HPMC yasimahla inokugcina uzinzo lweepropathi zayo zomzimba kunye nekhemikhali phantsi koluhlu olubanzi lweemeko zokusingqongileyo kwaye zandise ubomi bemveliso.

Ukhuseleko oluphezulu: ekutyeni kunye namashishini amayeza, i-sulfur kunye nemikhombathi yayo inokubangela ukungahambi kakuhle okanye ezinye izinto ezigwenxa kwabanye abantu. Ke ngoko, i-HPMC yasimahla ithathelwa ingqalelo kule mimandla kwaye ilungele uluhlu olubanzi lwamaqela abathengi.

Ukwandiswa kweendawo zesicelo: Ngenxa yokucoceka kwayo phezulu kunye nokhuseleko, i-HPMC engasetyenziswanga kungekuphela nje kwizicelo eziqhelekileyo zokuthambisa, kodwa zifana nezicelo eziphezulu ezifuna iziyobisi eziphakamileyo, ezifana nezixhobo zokutya.

Umahluko kwiinkqubo zemveliso
Ukuveliswa kwe-HPMC ye-S-freec kuhlala kubandakanya la manyathelo alandelayo:

Ukukhetha izinto ezingafunekiyo: Khetha izixhobo eziphezulu zeseli ezicocekileyo ukuqinisekisa ukuba izixhobo ezingaphantsi zikho okanye i-sulfur encinci kakhulu.

Inkqubo yokuhlaziya: Ngexesha lokuphendula kwe-Etheriya, i-Sulfur-free i-catalysts kunye nezongezo zisetyenziselwa ukuphepha ukuqaphela kwesalfure.

Unyango lwasemva kwexesha: Ngexesha lokuhlamba kunye nokomisa kwenkqubo yemveliso, imithombo yamanzi amsulwa kunye nezixhobo ezingaqhelekanga zisetyenziselwa ukunciphisa umxholo wesalfure kwimveliso.

I-S-free hydroxypropyl methylcelcelsulose (i-HPMC) iyafana ne-HPMC eqhelekileyo kwipropathi esisiseko efana nesakhiwo semichiza, isizinza esiphezulu, sizinzo esiphezulu, sinezibonelelo ezibalaseleyo kwezinye iindawo zokuphela kwesicelo. Ngeenkqubo ezingqongqo ngakumbi kunye nolawulo lomgangatho, i-HPMC ye-S-freec ibonelela ngokukhethwa okuthembekileyo kwizicelo ezifuna ukucoceka okuphezulu kunye nokungcola okuphantsi.
