4. Habka kala dirista Hydroxypropyl methylcellulose (HPMC):
Marka alaabta hydroxypropyl methylcellulose (HPMC) si toos ah loogu daro biyaha, way isku milmi doonaan ka dibna way milmi doonaan, laakiin kala diriddu waa mid aad u gaabis ah oo adag. Waxaa hoos ku qoran saddex hab oo kala diris ah oo la soo jeediyay, isticmaalayaashuna waxay dooran karaan habka ugu habboon iyadoo loo eegayo isticmaalkooda:
1. Habka biyaha kulul: Maadaama hydroxypropyl methylcellulose (HPMC) uusan ku milmin biyaha kulul, marxaladda bilowga ah ee hydroxypropyl methylcellulose (HPMC) si siman ayaa loogu kala firdhin karaa biyaha kulul, ka dibna marka la qaboojiyo, habka caadiga ah ee saddex A waxaa lagu qeexay sidan soo socota:
1). Biyaha kulul ee loo baahan yahay ku rid weelka oo ku kululee ilaa 70°C. Si tartiib ah ugu dar hydroxypropyl methylcellulose (HPMC) adigoo si tartiib ah u walaaqaya, hydroxypropyl methylcellulose (HPMC) wuxuu bilaabaa inuu dul sabeeyo biyaha dushooda, ka dibna si tartiib tartiib ah ayuu u sameeyaa slurry, qabooji slurry-ka marka la walaaqayo.
2). Kuleyli 1/3 ama 2/3 (qadarka loo baahan yahay) oo biyo ah weelka oo ku kululee ilaa 70°C. Sida waafaqsan habka 1), ku kala firdhi hydroxypropyl methylcellulose (HPMC) si aad u diyaariso dareeraha biyaha kulul. Kadib ku dar inta hartay ee biyaha qabow ama biyaha barafka ah weelka, ka dibna ku dar dareeraha biyaha kulul ee hydroxypropyl methylcellulose (HPMC) ee kor ku xusan biyaha qabow, oo walaaq, ka dibna qabooji isku darka.
3). Ku dar 1/3 ama 2/3 oo ah biyaha loo baahan yahay weelka oo ku kululee ilaa 70°C. Sida waafaqsan habka 1), ku kala firdhi hydroxypropyl methylcellulose (HPMC) si aad u diyaariso dareeraha biyaha kulul; Inta soo hartay ee biyaha qabow ama barafka ah ayaa markaa lagu daraa dareeraha biyaha kulul, isku darkana waa la qaboojiyaa ka dib marka la walaaqo.
2. Habka isku darka budada: walxaha budada ah ee hydroxypropyl methylcellulose (HPMC) iyo tiro la mid ah ama ka badan oo ah maaddooyinka kale ee budada ah ayaa si buuxda loogu kala firdhiyaa isku darka qalalan, ka dibna lagu milmaa biyo, ka dibna hydroxypropyl methylcellulose Base cellulose (HPMC) waa la milmi karaa iyada oo aan la isku darin. 3. Habka qoynta dareeraha dabiiciga ah: horay u kala firdhi ama qoyan hydroxypropyl methylcellulose (HPMC) oo leh dareere dabiici ah sida ethanol, ethylene glycol ama saliid, ka dibna ku milmi biyo. Waqtigan, 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 qaro-qafiye, kala firdhiye, emulsifier iyo wakiil sameeya filimada. Badeecooyinkeeda heerka warshadaha ah waxaa loo isticmaali karaa kiimikooyinka maalinlaha ah, elektarooniga, resins-ka synthetic-ga, dhismaha iyo dahaarka.
1. Polymerization-ka joojinta:
Soo saarista resins-ka synthetic-ga sida polyvinyl chloride (PVC), polyvinylidene chloride iyo copolymers-ka kale, polymerization-ka suspension-ka ayaa inta badan la isticmaalaa waana lagama maarmaan in la xasiliyo joojinta monomers-ka hydrophobic-ga ee biyaha. Iyada oo ah polymer-ka biyaha ku milma, alaabada hydroxypropyl methylcellulose (HPMC) waxay leeyihiin firfircooni dusha sare oo aad u fiican waxayna u dhaqmaan sidii wakiil ilaalin colloidal ah, kaas oo si wax ku ool ah uga hortagi kara isu-ururinta walxaha polymer-ka. Intaa waxaa dheer, inkasta oo hydroxypropylmethylcellulose (HPMC) uu yahay polymer-ka biyaha ku milma, haddana si yar ayuu ugu milmaa monomers-ka hydrophobic-ga wuxuuna kordhiyaa daloolka monomers-ka kaas oo laga soo saaro walxaha polymer-ka, si ay u siiso polymers awood aad u fiican oo ay ku saari karaan monomers-ka harsan iyo kor u qaadida nuugista balaastikada.
2. Marka la samaynayo qalabka dhismaha, hydroxypropyl methylcellulose (HPMC) waxaa loo isticmaali karaa:
1) Wakiilka dhejiska iyo dahaarka ee cajaladda dhejiska ku salaysan gypsum-ka;
2). Xidhitaanka lebenka, taayirada iyo aasaaska ku salaysan sibidhka;
3). Stucco ku salaysan plasterboard;
4) Malaas qaab-dhismeed oo ku salaysan sibidh;
5). Qaaciddada rinjiga iyo rinjiga ka saarta.
