Hydroxypropyl methylcellulose (HPMC) sidoo kale waxay leedahay awood dhumuc leh, caabbinta milixda, budada dambaska hoose, xasilloonida PH, haynta biyaha, xasilloonida cabbirka, hantida samaynta filim heer sare ah, iyo caabbinta enzyme ballaaran, sifooyinka kala firidhsan sida jinsiga iyo dhejiska
Saddex, sifooyinka hydroxypropyl methylcellulose (HPMC):
Alaabtu waxay isku daraysaa waxyaabo badan oo jidheed iyo kiimiko ah si ay u noqdaan badeeco gaar ah oo leh adeegsiyo badan, sifooyinka kala duwanna waa sida soo socota:
(1) Biyo-haysashada: Waxay ku hayn kartaa biyaha dusha sare sida looxyada sibidhka gidaarka iyo lebennada.
(2) Sameynta filimka: Waxay sameyn kartaa filim hufan, adag oo jilicsan oo leh caabbinta saliidda ee heer sare ah.
(3) Solubility organic: Alaabta waxay ku milmaysaa qaar ka mid ah dareerayaasha organic, sida ethanol/biyaha, propanol/biyaha, dichloroethane, iyo nidaam dareere ah oo ka kooban laba dareere organic.
(4) Heerarka kulaylka: Marka xalka aqueous ee alaabta la kululeeyo, waxay samayn doontaa jel, iyo jel la sameeyay waxay noqon doontaa xal mar kale qaboojinta ka dib.
(5) Dhaqdhaqaaqa dusha sare: Bixi dhaqdhaqaaqa dusha ee xalka si loo gaaro emulsification loo baahan yahay iyo kolloid ilaalinta, iyo sidoo kale xasilinta wajiga.
(6) Joojinta: Waxay ka hortagi kartaa roobabka qaybo adag, sidaas darteed waxay joojinaysaa sameynta sediment.

4. Habka kala dirida Hydroxypropyl methylcellulose (HPMC):
Marka alaabada hydroxypropyl methylcellulose (HPMC) si toos ah loogu daro biyaha, way xinjireen ka dibna way milmi doonaan, laakiin milankani waa mid gaabis ah oo adag. Waxaa jira saddex qaab oo la soo jeediyay oo kala diri ah hoosta, isticmaalayaashuna waxay dooran karaan habka ugu habboon iyadoo loo eegayo isticmaalkooda:
1. Habka biyaha kulul: Maadaama hydroxypropyl methylcellulose (HPMC) aysan ku milmin biyaha kulul, marxaladda bilowga ah ee hydroxypropyl methylcellulose (HPMC) ayaa si siman loogu kala firdhi karaa biyaha kulul, ka dibna marka la qaboojiyo, saddex Habka caadiga ah ayaa lagu sifeeyaa. soo socota:
1). Ku rid inta loo baahan yahay ee biyaha kulul weelka oo kuleyl ilaa 70 ° C. Si tartiib ah ugu dar hydroxypropyl methylcellulose (HPMC) si tartiib tartiib ah u walaaq, hydroxypropyl methylcellulose (HPMC) wuxuu bilaabaa inuu ku dul sabeeyo biyaha dushiisa, ka dibna si tartiib ah u samee slurry, qabooji slurry hoos walaaqaya .
2). Kuleyli 1/3 ama 2/3 (qadarka loo baahan yahay) ee biyaha weelka oo kuleyl ilaa 70 ° C. Marka loo eego habka 1), kala firdhi hydroxypropyl methylcellulose (HPMC) si aad u diyaarisid biyo kulul ka dib ku dar inta soo hadhay ee biyaha qabow ama biyaha barafka ee weelka, ka dibna ku dar kor ku xusan hydroxypropyl methylcellulose (HPMC) biyo kulul. biyo qabow, oo walaaq, ka dibna qabooji isku dar ah.
3). Ku dar 1/3 ama 2/3 qiyaasta biyaha loo baahan yahay weelka ku shub oo kuleyl ilaa 70 ° C. Marka loo eego habka 1), kala firdhi hydroxypropyl methylcellulose (HPMC) si aad u diyaariso slurry biyaha kulul; Inta soo hartay ee biyo qabow ama baraf ah ayaa markaa lagu daraa slurry biyaha kulul iyo isku dar ah waa la qaboojiyey ka dib marka la walaaqo.
2. Habka isku dhafka budada: Qaybaha budada hydroxypropyl methylcellulose (HPMC) iyo qadar siman ama ka badan oo ah maaddooyinka kale ee budada ah ayaa si buuxda loogu kala firdhiyey isku-dhafka qallalan, ka dibna lagu milmo biyaha, ka dibna hydroxypropyl methylcellulose Base cellulose (HPMC) waa la kala diri karaa iyada oo aan la kicin. . 3. Habka qoynta dareeraha dabiiciga ah: horay u kala firdhi ama qoyan hydroxypropyl methylcellulose (HPMC) oo leh dareerayaasha organic sida ethanol, ethylene glycol ama saliid, ka dibna ku milmi biyo. Waqtigaan, hydroxypropyl methylcellulose (HPMC) sidoo kale si habsami leh ayaa loo milmi karaa.
5. Isticmaalka ugu muhiimsan ee hydroxypropyl methylcellulose (HPMC):
Hydroxypropyl methylcellulose (HPMC) waxaa loo isticmaali karaa sidii dhumuc, kala firdhiye, emulsifier iyo wakiilka filim samaynta. Alaabteeda heerka warshadaha waxaa loo isticmaali karaa kiimikooyinka maalinlaha ah, elektiroonigga, resins-ka synthetic, dhismaha iyo dahaarka.
1. polymerization hakinta:
Soo saarista xabagta synthetic sida polyvinyl chloride (PVC), chloride polyvinylidene iyo copolymers kale, polymerization hakinta ayaa inta badan la isticmaalaa waana lagama maarmaan si loo dejiyo joojinta monomers hydrophobic ee biyaha. Sida polymer-ka biyaha-milmi leh, alaabada hydroxypropyl methylcellulose (HPMC) waxay leeyihiin waxqabad dusha sare ah oo aad u fiican waxayna u dhaqmaan sidii wakiilka ilaalinta kolloidal, kaas oo si wax ku ool ah uga hortagi kara isku-darka qaybaha polymer. Intaa waxaa dheer, in kasta oo hydroxypropylmethylcellulose (HPMC) ay tahay polymer-biyood-milmi leh, waxay sidoo kale wax yar ku milmi kartaa monomers hydrophobic waxayna kordhisaa porosity ee monomers-ka kaas oo qaybaha polymeric laga soo saaro, si ay u siiso polymers awood aad u fiican si looga saaro monomers haraaga ah. iyo kor u qaadista nuugista balaastikada.
2. Samaynta qalabka dhismaha, hydroxypropyl methylcellulose (HPMC) waxaa loo isticmaali karaa:
1). Walalaha xabagta iyo xabagta ee sharoobada xabagta ku salaysan ee gypsum;
2). Isku-xidhka lebenka sibidhka ku salaysan, tiirarka iyo aasaaska;
3). stucco ku salaysan balaastarka;
4). balastar dhisme ku salaysan sibidhka;
5). In qaacidada rinjiga iyo rinjiyeynta.
