I-HYDROXYPOPLL ye-HydroxyPOpyl MethylcelcelUlose (HPMC)

I-HYDROXCOPLLL ye-Hydroxypropyl Methylcelcellulose (HPMC) yimveliso ye-ionic ye-ionic ye-ionise eyenziwe kwi-selsulose yendalo emva kokulungiswa kweekhemikhali. Izinto zayo eziphambili ze-cotton okanye i-pulp yenkuni, kwaye ilungiselelwe ngeenkqubo ezininzi ezinjenge-alkalization, i-etheriya, yokuhlamba, kunye nokomisa. Kungenxa yokuba i-HPMC inesigebenga esihle, ukunqunyanyiswa, ukusasazeka, ukungqubana, ukuqulunqwa kwefilimu, i-Cosloid, i-Costoid, i-cosmetive, i-cosmetics, i-cosmetics, amayeza kunye namanye amayeza.

1. Iimpawu ezisisiseko ze-HPMC
Ukungasebenzi kunye nokuzinza
I-HPMC inyibilikisa emanzini abandayo kunye nezinye iinyibilikisi zezinto eziphilayo kwaye zinomoya ofanelekileyo. Inganyibiliki emanzini ashushu, kodwa inokwenza ijeli emanzini, kwaye isisombululo esichithekayo sinokufakeli okuphezulu kunye nozinzo. Ukongeza, i-HPMC inozinzo oluqaqambileyo, kwaye ihlala igcina intsebenzo ezinzileyo kuluhlu lwe-3 ~ 11.

Ukugcinwa kwamanzi kunye nokutyibilika
I-HPMC inomgangatho ophezulu wokugcina amanzi kwaye inokuthintela ukuphulukana namanzi. Le mpahla iyenza idlale indima ebalulekileyo ekufundeni kudaka lokwakha kwicandelo lokwakha, ukuphucula ukusebenza kokwakha kunye nokuphepha ukuqhekeka. Ukongeza, i-HPMC yi-tickener esebenzayo, kwaye isisombululo sayo esinamandla sinokunika i-viscofity ebalulekileyo kwindlela ephantsi.

Ipropathi yokwakha ifilimu
I-HPMC inokwenza ifilimu enzima nengabonakaliyo kumphezulu wezinto, ngokuchasene neoyile yeoyile kunye neepropathi ze-enzyme. Le mpahla yenza ukuba isetyenziswe ngokubanzi kwi-cares, iingubo zangaphantsi zeziyobisi kunye namanye amasimi.

Umsebenzi womphezulu
I-HPMC inesisulelo esifanelekileyo kunye neepropathi ze-colloid ezikhuselayo, kwaye zinokusasazeka kakhulu kwiinkqubo ezininzi, ngaloo ndlela ziphucule ukufana nokuzinza kwenkqubo.

I-2. Inkqubo yemveliso ye-HPMC
Ukuveliswa kwe-HPMC yeBanga leShishini ikakhulu kubandakanya la manyathelo alandelayo:

Ukulungiswa kwezinto ezibonakalayo
Sebenzisa isellulose yendalo (umqhaphu okanye i-cotton okanye i-pulp yenkuni) njengezixhobo eziluhlaza, kungeniswa kwisisombululo se-alkali sonyango lwe-alkali ukunyusa i-chain ye-selsulose molecular.

Ukuphendula kwe-ether
Kwisiseko se-alkal ye-alkal, i-etherhesing ye-E-Eler (njenge-methyl chloride kwaye i-proplene oxide) yongezwa, kwaye i-Etheristic yokuphendula yenziwa kwi-HydroxlyAse.

Unyango
Imveliso yokuphendula iphantsi kwetyala, ukuhlamba, ukomisa kunye nenkqubo yokutyhoboza amanyathelo okufumana iimveliso ze-HPMC zokunxibelelana neemfuno ezahlukeneyo.

3. Iindawo ezisetyenzisiweyo ze-HPMC
Ishishini lokwakha
I-HPMC licandelo elibalulekileyo kumdaka owomileyo, i-tile ongenayo, i-podty powder kunye nokuthuka kwamanzi. Imisebenzi yayo yokugcina amanzi kunye nendawo yokugcina amanzi iphucula intsebenzo yokwakha, esenza izinto zokwakha zihlala zomelele kwaye zilula ukusebenza.

Iingubo kunye neepeyinti
I-HPMC inokusetyenziswa njenge-tickener, isisasazi kunye nokuzinza kwi-carlungs ukubonelela ngeziphumo zokuhamba nge-iyunifonti, ukuphucula intsebenzo kunye nokuphucula iipropathi ezichasene nemali.

Amayeza kunye nokutya
Kumzi-mveliso wamachiza, i-HPMC ihlala isetyenziselwa ukulungiselela izixhobo zokuhlambela kunye neepilisi zeetafile zamayeza, kwaye zikwasetyenziselwa ukukhutshwa okulawulwa kwamalungiselelo okukhulula. Kuluhlu lokutya, i-HPMC isetyenziswa njenge-emulsifier, i-thickener kunye nokuzinzisa kwiindawo ezahlukeneyo zokutya.

Iichemicals zemihla ngemihla
I-HPMC isetyenziswa ngokubanzi kwi-shampoo, iimveliso zokhathalelo lwesikhumba kunye nezinye iimveliso, ezibonelela ngokuzinza, iziphumo zokonga kunye namava agqwesileyo.

4. Izibonelelo zohambo kunye nophuhliso lwe-HPMC yeBanga le-HPMC
Izibonelelo
I-HPMC yeBanga lokuGqibela i-HPMC ikhuselekile kwaye inobuhlobo kwindalo, inoluhlu olubanzi lwemithombo, kwaye lusebenza ngokwahlukeneyo. Inokuhlangabezana neemfuno zemveliso yanamhlanje yezinto ezifanelekileyo, eziluhlaza kunye nezona zinto zininzi. Kwangelo xesha, ukusetyenziswa kwayo kuyinto encinci kodwa impembelelo kubalulekile, kwaye ineendleko eziphezulu.

Imeko yophuhliso
Ngokuphuhliswa kwezakhiwo eziluhlaza, iingubo ezinobuhlobo ngokusingqongileyo kunye neendawo eziphakamileyo zamayeza, imfuno ye-HPMC iya kuqhubeka ikhula. Kwangelo xesha, inkqubo yemveliso ye-HPMC ilungiselelwe kwicala lokusebenza eliphezulu, ukusetyenziswa okuphantsi kunye nongcoliseko olusezantsi, ukuphucula izibonelelo zayo zoqoqosho nezendalo.

I-Hydroxdypropyl ye-HydroxylCopyl Methylceltulose iye yaba yinto ebalulekileyo kwaye ibalulekile kwi-aržilies kwimveliso yemizi-mveliso kunye neekhemisi zayo ezifanelekileyo zomzimba kunye neekhemikhali. Kwixa elizayo, ngokuqhubela phambili kwetekhnoloji kunye nokwandiswa kweendawo zesicelo, amathuba entengiso ye-HPMC aya kubanzi. Ngophando oluqhubekayo nophuhliso kunye nezinto ezintsha, ukusebenza kwalo kuya kuphuculwa ngakumbi ukuhlangabezana neemfuno zamashishini ahlukeneyo.
