Haynta Biyaha ee Hydroxypropyl methylrcellerose ether
Haysashada biyaha ee qallalan ee qallalan ayaa waxaa ka mid ah madaafiicda waxaa ka mid ah awoodda hoobiyeyaasha loo qabanayo iyo qufulka biyaha. Kordhinta mowqifka ee hydroxypropyl methylcelrellase ether, ayaa sifiican haynta biyaha. Sababtoo ah qaab dhismeedka unugyada ayaa waxaa ku jira hyroxyl iyo dammaanad ka timaadda 'oksijiin' oo ku saabsan hydroxyl iyo dammaanad-ka-xire-daloolka si loo sameeyo biyo-hayaha biyaha, sidaa darteed biyaha xorta ah, sidaa darteed door haynta biyaha.
Naafanimada hydroxypropyl byluyl celther ether
1. Qolka unugyada adag ee ether etherku waa fududahay in lagu kala qaybiyo biyaha iyada oo aan lahayn biyaha ismaglaha, laakiin heerka kala diridda ayaa aad u gaabis ah. Cilldhiska ether ee ka hooseeya 60 mesh ayaa lagu kala diraa biyaha ilaa 60 daqiiqo.
2. Qoob-ka-cirifka walxaha wanaagsan ee loo yaqaan 'celcle walcal ether' waa sahlan tahay in lagu kala qaybiyo biyaha iyada oo aan lahayn biyaha, iyo heerka kala-baxa waa dhexdhexaad. Cilmiga Chetch Ether ka sarreeya 80 mesh ayaa lagu kala diraa biyaha ilaa 3 daqiiqo.
3. Ulgacal-ka-wanaagsan ee loo yaqaan 'Ultra-walcal walxaha ukunta ee ether ah ayaa si dhakhso leh ugu fida biyaha, si dhakhso leh ayuu u kala dirayaa, oo foosha foosha ayaa si dhakhso leh u sameeya. Cilmiga Chetch ee kor ku xusan 120 mesh oo biyo ah oo ku dhex milma 10-30 sekan sekan.
Qulqulka dareeraha hydroxypropyl methylrellalose etter, ayaa sifiican u haynta biyaha. Dusha sare ee unugyada loo yaqaan 'chether chether chether' ayaa isla markiiba kala firidhsan ka dib marka aad la xiriireyso biyo oo ay samayso ifafaale gel. Xulku wuxuu ku xidhaa sheyga si looga hortago moleekus biyo-xireennada inay sii wataan inay galaan. Mararka qaarkood si isku mid ah uma kala firidhsan karo oo kala diri karo xitaa ka dib ka darka muddada-dheer, sameynta xalka daruuraha daruuriga ah ee daruuriga ah ama ammadda. Walxaha fiican ee kala firidhsan oo kala milaan isla markaaba ka dib marka laga soo xidho biyaha si ay u sameeyaan viscosis labis ah.
Qiimaha phe ee hydroxypropyl methylrcelrellase ether (dib u soo celinta ama saamaynta xoogga hore)
Qiimaha pH ee hydroxypropyl methylulolose ether ether-ka ee guriga iyo dibedda ayaa asal ahaan la xakameynayaa qiyaastii 7, kaas oo ku jira gobolka aashitada. Sababta oo ah wali waxaa jira tiro badan oo ah qaab-dhismeedka giraanta-kolhydroglumos ee qaab dhismeedka molucalilal ee cell chether, giraanta aashka ah ayaa ah kooxda ugu weyn ee sababa dib u dhaca sibidhka. Giraanta aashsydrogloglucose wuxuu ka dhigi karaa ion kaalshiyamka xalka biyo-galka ah oo dhalisay xeryahooda molat-kalsium-ka-qaadida inta lagu gudajiro biqilka ion ee fuudhku, kahortaga samaynta kingstals-ka iyo kiriyoka kalsiyamka ee kaalshiyamka ah, iyo dib-u-dhigga fuuq-baxa sibidhka. geeddi-socod. Haddii qiimaha pH uu ku jiro gobolka alkaline, madaafiicda ayaa ka soo muuqan doonta dowlad-xoogga hore. Hadda inta badan qodobka isticmaal sodium kaarboon si aad u hagaajiso qiimaha pH. Sodium Carbonate waa nooc ka mid ah wakiilka deg-degga ah. Kaalinta sodium-ka waxay hagaajisaa waxqabadka dusha sare ee walxaha qulqulka, waxay sare u qaadeysaa isku-darka u dhexeeya walxaha, waxayna sii wanaajisaa aragtida madaafiicda. Isla mar ahaantaana, sodium carbonate si dhakhso ah ayaa isugu daraya ionsium-ka kaalshiyamka ah ee madaafiic ku jira in lagu saleeyo samaynta ettrihinte, iyo sibidhka si isdaba joog ah ayaa si dhakhso ah isugu jira. Sidaa darteed, qiimaha pH-ga waa in lagu hagaajiyaa iyadoo loo eegayo macaamiisha kaladuwan geedi socodka wax soo saarka dhabta ah.
Hawo u geysanaya guryaha ku saabsan hydroxypropyl byluyl celther ether
Saamaynta hawada ee hawada ee hydroxypropylyl methylcelrelose ether badanaa waa sababta oo ah celleulose ether sidoo kale waa nooc ka mid ah sagxadda. Waxqabadka is dhexgalka ee ether chether ayaa inta badan ka dhacda interface-ka-neefsashada gaaska. Marka hore, soo bandhigida xumbada hawada, waxaa ku xiga kala firidhsan iyo saamaynta qoynta. Ether ether-ka ayaa ka kooban kooxo alkyl ah, oo si weyn u yareeya xiisadda dusha sare iyo tamarta galmada ee biyaha, taasoo sahlanaysa in la abuuro xumbo aad u badan oo xirtay inta lagu gudajiro nidaamka aquering xalka aqueous.
Gel Gel Gel of hydroxypropyl byluyl celther ether
Ka dib markii ay jidka hydroxypropylyl ka dib markii lagu milmay hoobiyaha, daaqa methoxyl iyo yourroxypropyl silsilada molucalium-ka ayaa ka falceliya ionsium-ka iyo aluminium-ka sicirka si ay u sameeyaan jelji ah oo ka buuxiya madaafiic viscous ah. , Hagaajinta is-afgarad ee madaafiicda, ka ciyaar doorka buuxinta dabacsan iyo xoojinta. Si kastaba ha noqotee, markii matrix-ka isku-darka uu saaran yahay cadaadis, polymer ma ciyaari karo door taageerida adag, sidaa darteed xoogga iyo saamiga isku-darka ee hoos u dhaca madaafiicda.
Samaynta Filimka ee Hydroxypropyl byluyl celther ether
Ka dib markii hydroxypropyl cellyl bluether loo soo daro biyo-baxa, lakabka khafiifka ah ee filimka cinjirka ah waxaa loo sameeyaa inta udhaxeysa walxaha daboolka. Filimkan wuxuu leeyahay saameyn xirxiran wuxuuna wanaajiyaa dusha sare ee qallajinta madaafiiqda. Sababo la xiriira haynta biyaha wanaagsan ee biyaha hydroxypropyl methylulose ether, oo lagu keydiyo madaafiic, taas oo lagu keydinayo hawo-mareenka iyo horumarinta xoogga xidhiidhka hoosaadka, iyo isla waqtigaas Waxay wanaajisaa wadajirka madaafiicda, ka dhigaya hoobiyeyaasha leh caag wanaagsan iyo dabacsanaan wanaagsan, waxayna yareysaa jahwareerka iyo hoobiyaha.
