Hordhac ku saabsan hydroxypropylykyl
Hydroxypropyl methylcellulose, also known as hypromellose and cellulose hydroxypropyl methyl ether, is made of highly pure cotton cellulose as raw material, which is specially etherified under alkaline conditions. HPMC waa budo cad, dhadhan la'aan, ur la'aan, aan sun lahayn, oo gabi ahaanba isma beddelin jirka bini-aadamka oo ka soo baxa jidhka. Shayga ayaa biyo ku dhex milma, laakiin aan ku dhexjiro biyo kulul. Xalka aqueous waa walax aan muuqan oo midab leh. HPMC waxay leedahay qaro weyn, emulsifiyeynta, filimka, kala firidhsan, isku-darka qoyaanka, asiidhion, aashitada, aashitada, maaddada, dhajinta, dhajinta, dhoobada, harooyinka polymomemization.
1. Waxa ku jira kaalshiyamka ee hooseeya ee kaalshiyamka cawlan iyo saamiga aan habooneyn ee Cao iyo CA (Oh) 2 ee kaalshiyamka cawlan ayaa sababi doonta lumis budada ah. Haddii ay wax ku yeelato HPMC, markaa haddii biyuhu haynta haynta HPMC liidato, waxay sidoo kale sababi doontaa lumis budo ah. Luqadaha budada ah ee budada ah ee la xiriira hydroxypropyl methylcelrelose? Budada budada ah ee budada isbadalka ah ayaa inta badan la xidhiidha tayada kaalshiyamka ash, wax yarna waxoogaa lagu sameeyo HPMC.
2. Shaqada ugu muhiimsan ee hydroxypropyl methylcelrellase waa haynta biyaha, oo ay ku xigto dhumuc weyn. Budada wareega, illaa iyo inta ay haynta biyuhu wanaagsan yihiin oo ay taagan tahay mid taagan (70,000-80,000), sidoo kale waa macquul. Dabcan, waxa kor u kacaya sawirka, ayaa sifiican u haynta biyaha qaraabada ah. Markuu viscosisku ka badan yahay 100,000, codku wuxuu saameyn ku yeelan doonaa haynta biyaha. Mar dambe ma aha.
Waa maxay mowqifka hydroxypropyl methylcelrelosuse (HPMC)?
Budada wareega guud ahaan waa 100,000 yuan, iyo shuruudaha hoobiyeyaasha ayaa ka sareeya, oo 150,000 yuan ayaa looga baahan yahay isticmaal fudud.
3. Waa maxay ashyaa'da ugu weyn ee ceeriin ee hydroxypropyl methylcelrelose? Alaabada ugu weyn ee ceeriin ee hydroxypropylylulolose (HPMC): Waxaa lagu safeeyey suufka suufka ah, phimylne chloride, pretylne chloride, presylne-ka, iyo waxyaabaha kale ee ceeriin, aashitada, toluene, toopropanol, iwm.
4. Waa maxay sababta urta urta hydroxypropyl methylcelrelosuse? Hydroxypropyl methylcelrelose waxaa soo saaray habka dareeraha ah ee loo adeegsado toluene iyo isopropanol inay yihiin solvents. Haddii maydhistu aysan aad u fiicneyn, waxaa jiri doona ur hadha.
5. Midda leh viscosity sare ayaa leh haynta biyaha ka fiican, si buuxda (gabi ahaanba), oo mid ka mid ah kan leh viscosity sare ayaa si fiican loogu isticmaalaa hoolkan. Waa maxay tilmaamayaasha farsamada ee ugu weyn? Nudroxypropyl iyo viscosity, inta badan dadka isticmaala ayaa ka walaacsan labadan tilmaamayaasha.
Ifafaalku ma yahay madaafiic la xidhiidha madaafiicda ku jirta hydroxypropyl methylcelrelose?
Waqti ka hor, macmiil ayaa sheegay in sheygu uu lahaa Efforessscence, oo uu ku buufin. The Shantood: Hawsha ugu weyn waa in dhabarka la daboolo, oo la buuxiyo, loona kordhiyo kudhigga u dhexeeya derbiga iyo maaddada dusha sare. Isticmaal aad u yar, kaliya ku buufi lakabka khafiifka ah derbiga. Halkan waxaa ah sawir ah ifafaale efflorescenes in macmiil ii soo diray: Sawirka falcelinteyda ugu horreysa ayaa ah in xaqiiqdi aysan ahayn sababta oo ah in hydroxypropyl methylcelrelosuse uusan la jaan qaadi karin wax kasta oo ka mid ah qoryaha ka falgala. Inagamase ifafaale waa: la taaban karo caadi ah, markii ay ku dhacdo hawada ama qoyaanka sicir-biyo-qabka ah, marka uu heerkulku kor u kaco, oo uumiga biyuhu wuxuu ka dhacaa hydrolide-ka. derbiga. Iyada oo ay jirto uumiga tartiib-tartiib ah ee biyaha, hydroxide-ka waxaa lagu saleeyaa dusha sare ee sibidhka la taaban karo, kaas oo aruurinaya waqti ka dib, taas oo ka dhigeysa qurxinta asalka ah oo aan mar dambe u hoggaansamin derbiga, tirtirka, goynta, iyo goynta ayaa dhici doonta. Hawshan waxaa loo yaqaan "Pan-Alkali". Marka ma aha in Ubiqunol ay sababtay hydroxypropyl methylrcellulose
Macaamiilku wuxuu kaloo xusay ifafaale: Waxaa lagu buufiyey Biyo-mareenka ee loo yaqaan 'pan-akaline', laakiin kama muuqan doono in silikon la taaban karo ee cusbada darbiyada loo isticmaalo (cusbada alkaline adag) waa mid aad u sarreeya. Efflorescence oo ay keento uumiga biyaha loo isticmaalo buufin buufin. Si kastaba ha noqotee, majiraan silical derbiga leben ee lagu ridayo oo aan wax ka beddelin. Marka ifafaale waafafaale ka ah encloressscence wax shaqo ah kuma lahan buufinta.
Xalka:
1. Waxyaabaha cad ee salka ku dhaca sibidhka salka la taaban karo waa la dhimay.
2. U adeegso wakiilka dahaarka ka soo horjeedda ee Anti-Alkali, Xalku wuxuu galaa dhagaxa si uu u xalliyo jajabka, sidaa darteed biyahaas, CUTE iyo walxaha kale ma jari karo ifafaalaha pan-alkaline.
3. Ka hortag galitaanka biyaha, hana ku saydhin biyo badan ka hor dhismaha.
Daaweynta ifafaaleynta digsiga-alkaline:
Wakiilka nadaafadda dhagaxa ee suuqa ayaa la isticmaali karaa. Wakiilkan nadiifinta ayaa ah dareere aan midab lahayn oo midab leh oo laga sameeyay sawadaha aan in-ionc-ka iyo dareeraha. Waxay saameyn gaar ah ku leedahay nadiifinta meelaha dhagaxyada dabiiciga ah ee dabiiciga ah. Laakiin ka hor intaan la isticmaalin, iska hubi inaad sameyso xannibaadda muunad muunad ah si aad u tijaabiso saamaynta oo aad go'aan ka gaarto inaad isticmaasho.
