Hydroxypropyl Methylcellulose (HPMC)

Hydroxypropyl Methyl Cellulose oo caadi ahaan loo yaqaan Hypromellose, HPMC, waa eter-ka aan-ionic cellulose-ka ahayn ee ka soo jeeda polymers-ka dabiiciga ah sida suufka la safeeyey ama saxarka alwaax iyada oo loo marayo nidaam kiimiko oo taxane ah. Waxay soo bandhigaysaa sida budo cad oo aan ur lahayn, aan sun ahayn, iyo dhadhamin la'aan. Walaxdani waxay si dhib la'aan ah ugu milmaysaa biyaha kulul iyo kuwa qaboobaha labadaba, samaynta xal hufan oo muuqda oo leh noocyo kala duwan oo hanti ah, taas oo ka dhigaysa mid aad loo raadsado codsiyo kala duwan.

HPMC waxay ku faantaa sifooyin gaar ah sida dhumuc aad u fiican, xidhidh, kala firdhisan, emulsifying, film samaynta, laalida, adsorbing, gelling, dusha-firfircoon, haynta biyaha, iyo ilaalinta guryaha kolloid. Isticmaalkeeda baahsan ayaa ku baahsan warshadaha oo ay ku jiraan dhismaha, daawooyinka, cuntada, PVC, ceramics, iyo alaabta daryeelka shakhsi / guriga.

Qaybta dhismaha, HPMC waxay u adeegtaa sidii dhumuc weyn oo loogu talagalay hoobiyeyaasha qallalan, xabagta tile, rinjiga biyaha ku salaysan, dhejinta gidaarka, iyo taxanaha hoobiye dahaarka kulaylka. Intaa waxaa dheer, waxay u heshaa codsiga sidii qalab dawo ah iyo qayb cunto, oo gacan ka geysaneysa soo saarista PVC, ceramics, iyo saabuunta. HPMC sidoo kale waa shay caadi ah oo ku jira dunta, alaabta daryeelka shakhsi ahaaneed, iyo alaabta daryeelka guriga.

Maxaa Hydroxypropyl Methylcellulose loo isticmaalaa?

sharaxaad2

Hydroxypropyl Methylcellulose (HPMC) waa polymer isku dhafan oo leh codsiyo kala duwan oo warshado kala duwan ah. Sifooyinkeeda gaarka ah waxay ka dhigaan mid qiimo leh qaabab kala duwan. Waa kuwan qaar ka mid ah isticmaalka caadiga ah ee Hydroxypropyl Methylcellulose:

Waa maxay guryaha guud ee HPMC?

sharaxaad2

Hydroxypropyl Methylcellulose (HPMC) waa soosaar cellulose leh noocyo kala duwan oo sifooyin ah oo ka dhigaya mid faa'iido u leh warshado kala duwan. Waa kuwan sifooyinka guud ee HPMC:

Qaab dhismeedka Kiimikada:

HPMC waa polymer semi-synthetic ah oo laga soo qaatay cellulose, polymer dabiici ah oo laga helo gidaarada unugyada dhirta.

Qaab dhismeedka kiimikada ee HPMC waxaa ka mid ah hydroxypropyl iyo methyl kooxaha ku xiran laf dhabarta cellulose.

Xalka:

HPMC waxay ku milmi kartaa biyaha, samaynta xal cad, taas oo sahlaysa in lagu daro hababka aqueous.

Viscosity:

Mid ka mid ah sifooyinka muhiimka ah ee HPMC waa awoodda ay u leedahay inay wax ka beddesho viscosity. Waxay ku siin kartaa dhumuc xalalka iyo qaabaynta, wax ku biirinaysa hagaajinta texture iyo shaqaynta.

Samaynta Filim:

HPMC waxay leedahay sifooyin filim samaynta, taas oo ka dhigaysa mid faa'iido u leh codsiyada halka la rabo samaynta filim difaac ama isku xidhan.

Gelation-ka kulaylka:

HPMC waxa ay muujisaa kulka kulaylka, taasoo la micno ah viscosity-kiisu korodho heerkulka. Hantidan waxaa inta badan loo isticmaalaa habaynta daroogada la xakameeyey.

Waxqabadka Dusha sare:

HPMC waxay yeelan kartaa sifooyin u eg surfactant, kor u qaadida emulsification iyo kala firdhisanaanta qaababka qaarkood.

Xasilooni

HPMC waxay gacan ka geysataa xasiloonida ka joojinta, emulsions, iyo qaabab kale iyada oo ka hortagaysa dejinta walxaha ama kala-goynta.

Haynta Biyaha:

HPMC waxay awood u leedahay inay biyaha ceshato, taasoo ka dhigaysa mid qiimo leh codsiyada halka ilaalinta qoyaanku ay lagama maarmaan tahay, sida qalabka dhismaha.

Adhesion:

Warshadaha kala duwan, HPMC waxay wanaajisaa xabagta, hadday tahay qalabka dhismaha sida madaafiicda ama dahaarka iyo xabagta.

Firfircoonida Kiimikada:

HPMC waa mid kimiko ahaan aan firfircoonayn, taasoo la macno ah in aanay ka falcelinayn qaybaha kale ee qaabaynta, hubinta xasiloonida iyo la jaanqaadida agabyo kala duwan.

Dareenka pH:

Sifooyinka HPMC waxaa saameyn ku yeelan kara pH ee xalka ama qaabeynta. Guud ahaan way xasilloon tahay marka loo eego cabbirka pH ballaaran.

Dejinta heerkulka:

HPMC waxa loo tixgaliyaa in ay tahay mid noolaha, taas oo faa'iido u yeelan karta qaar ka mid ah codsiyada deegaanka iyo kuwa waara.

Guryahaan guud waxa ay HPMC ka dhigayaan polymer-ka la taaban karo oo si weyn looga isticmaalo warshadaha sida dawooyinka, dhismaha, cuntada, waxyaalaha la isku qurxiyo, iyo kuwo kale. Awooddeeda wax ka beddelka sifooyinka rheological iyo functional of formulations wax ka tarta in ay ku dabaqi karo ballaaran.
