(I-HPMC) Yintoni umahluko kunye okanye ngaphandle kwezi?

I-1. I-HPMC yahlulahlulwe yanguhlobo lwangoko kunye nohlobo lokusasaza ngokukhawuleza

Uhlobo lwe-HPMC ngokufihlakeleyo luhambelana nonobumba u-S, kwaye i-GYSOxal kufuneka yongezwe ngexesha lenkqubo yemveliso.

Uhlobo lwe-HPMC kwangoko alongezi naziphi na iileta, ezinje nge "100000" lithetha "i-viscosity ye-viscosity ekhethekileyo ye-HPMCC".

2. Nge okanye ngaphandle okanye ngaphandle kwe-S, iimpawu zahlukile

Ukusasazeka ngokukhawuleza kwe-HPMC ngokukhawuleza xa idibana namanzi abandayo kwaye inyamalale emanzini. Ngeli xesha, ulwelo alunamfanekiso, kuba i-HPMC ichithwa njengamanzi ngaphandle kokupheliswa kokwenyani. Emva kwemizuzu emibini, i-viscosity ye-ulwelo ngokuthe ngcembe inyuka, yenza i-vick ebonakalayo ye-colloid.

I-HPMC ngokukhawuleza ingasasazwa ngokukhawuleza emanzini ashushu malunga nama-70 ° C. Xa iqondo lobushushu liye kwehla kubushushu obuthile, i-viscofity iya kuvela kancinci de kube kumiselwa i-collous ebonakalayo.

3. Nge okanye ngaphandle kwe-S, injongo yahlukile

I-HPMC ye-HPMC inokusetyenziswa kuphela kwi-pody powder nodaka. Kwiglue yeglue, ipeyinti kunye nokuhlamba iimveliso, kuya kubakho i-phenomenon yeqela kwaye ayinakusetyenziswa.

Ukusasazeka ngokukhawuleza i-HPMC inoluhlu olubanzi lwezicelo kwaye linokusetyenziswa kwi-podty powder, udaka, ubisi lweglue, ipeyinti, kunye nokuhlamba iimveliso ngaphandle kokuphikisana.

Indlela yokuphelisa

1. Thatha inani elifunekayo lamanzi ashushu, yibeka kwisitya kwaye usitshise ngaphezulu kwe-80 ° C, kwaye ngokuthe ngcembe ukongeza le mveliso phantsi kwemveliso ehamba kancinci. I-seluplose idadayo kumphezulu wamanzi ekuqaleni, kodwa ngokuthe ngcembe isasazeka inyanzelise iyunifomu. Isisombululo sapholwa xa sikhuthaza.

2. Ngenye indlela, ubushushu 1/3 okanye 2/3 zamanzi ashushu ngaphezulu kwe-85 ° C, ukongeza isellulose ukufumana amanzi ashushu, emva koko wongeza umxube osisiphumo.

3. I-mesh ye-selselose ilunge kakhulu, kwaye ifumaneka njengamasuntswana amancinci ancinci kumgubo ovuselelekileyo, kwaye ayinyibiliki ngokukhawuleza xa edibana namanzi ukwenza i-viscofity efunekayo.

I-4. Kancinci kwaye ngokongeza i-seluplose kubushushu begumbi, ishukumisa ngokuqhubekayo kude kusenziwa isisombululo esibonakalayo.

Zeziphi izinto ezichaphazela ukugcinwa kwamanzi kwe-hydroxlypropyl methylcelcelcelgulose?

Ukugcinwa kwamanzi kwi-hydroxypropyl methylcelcelsulose yemveliso ye-HPMC ngokwayo ihlala ichaphazeleka kwezi zinto zilandelayo:

I-1. Ukufana kwe-seluplose ether hpmc

Ngokucacileyo i-HPMC, i-MacxGyl kunye ne-hydroxypropoxyl zisasazwe ngokulinganayo, kwaye inqanaba lokugcina amanzi liphezulu.

I-2. Ubushushu be-thermal ye-thermal ye-sellulose ether hpmc

Ukuphakama kweqondo lobushushu be-thermal, ukuphakamisa inqanaba lokugcina amanzi; Ngaphandle koko, iphantsi inqanaba lokugcina amanzi.

I-3. I-Telupelose Ether HPMC Viscofity

Xa i-vickosity ye-HPMC inyuka, iqondo lokugcina amanzi liyanda; Xa i-viscosity ifikelela kwinqanaba elithile, ukwanda kwemilinganiselo yokugcina amanzi ethatyathwa ukuba iflethi.

Isixa esongeneyo se-selsulose ether hpmc

Inqanaba elikhulu le-iler i-erlulose i-HPMC yongezwa, iphakamile kwinqanaba lokugcina amanzi kunye nokulungileyo komsebenzi wokugcinwa kwamanzi.

Kuluhlu lwe-0.25-0.6% eyongezwayo, izinga lokugcina amanzi linyusa ngokukhawuleza ngokunyuka kwenani elongeziweyo; Xa ukongezwa konyuso lonyuka, ukunyusa imeko yeqondo lokugcina amanzi liyacothisa.
