I-HydroxyPOpyl Methylcelcelcelose yi-polymer ye-polymer edumileyo emanzini esenza isisombululo esicacileyo nesizinzileyo emanzini kwaye sisetyenziswa kakhulu kumashishini okwakha. Yinto engasekwe kwi-ionic esekwe kwi-selsulose esekwe kwi-selsulose-isekwe kwizinto ezibonakalayo eziphucula iipropathi ezinomtsalane zemveliso yokugqibela. Ukuqinisekisa ukusebenza komgangatho ophezulu we-hydroxypropyl methylceluplose, imveliso kufuneka ivavanywe kwaye ifanelekile ngaphambi kokusetyenziswa. Kweli nqaku, siza kuthetha ngeendlela ezintathu ezinokuthenjwa zokuchaza umgangatho we-hydroxlyproptl methylceluplose.
1. Uvavanyo lwe-viscosity
I-viscosity ye-hydroxypropyl methylcelgalose yiparamitha ebalulekileyo ukumisela umgangatho wayo. I-Viscosity yixhathisa i-fluid ukuba ihambe kwaye ilinganiswe kwi-centiipoise (CPS) okanye i-MPA.S. I-vickosity ye-hydroxypropyl methylcelcelsele ihlukahlukane nobunzima bemolekyuli kunye nenqanaba lokufakwa endaweni. Ukuphakama kwenqanaba lokufakwa endaweni, ukuthoba i-viscofity yemveliso.
Ukuvavanya i-viscosity ye-hydroxypropyl methylceltulose, inyibilikiswe inani elincinci lemveliso emanzini kwaye usebenzise uphawu lokulinganisa ukulinganisa i-viscofity yesisombululo. Uhlobo lwesisombululo kufuneka lube ngaphakathi kuluhlu olucetyiswayo olunikezwe ngumthengisi wemveliso. Imveliso elungileyo ye-hydroxypropyl methylcelcebalose imveliso kufuneka ibe ne-vikosity engaguqukiyo, ephawuleka ngobunyulu kunye ne-intermmuccal ye-sub.
I-2. Uvavanyo lokufaka endaweni
Iqondo lokufakwa endaweni libhekisa kumyinge wenani lamaqela e-hydroxyl kwi-selulose ethatyathwe yi-hydroxypropyl okanye amaqela e-methyl. Inqanaba lokufakwa endaweni yesalathiso sonyulu semveliso, ukuphakama kwenqanaba lokufakelwa, icocekile imveliso. Umgangatho ophezulu we-hydroxypropyl methylcelcelcelose iimveliso kufuneka zibe nenqanaba eliphezulu lokufaka endaweni.
Ukuvavanya inqanaba lokufakwa endaweni, isidili senziwa kunye ne-sodium hydroxide ne-hydrochloric acid. Chonga inani le-sodium hydroxide efunekayo ukuba angalawulwa ngu-hydroxypropyl methylcelgalose kwaye ubala isidanga sokufaka endaweni yefomula:
Inqanaba lokufaka
Inqanaba lokufakwa endaweni kufuneka libe ngaphakathi kuluhlu olucetyiswayo olunikezwe ngumthengisi wemveliso. Inqanaba lokufakwa endaweni ye-HydroxyPlPyPropyl ye-Methylcelcelcelsulose ibephakathi kuluhlu olucetyiswayo.
I-3. Uvavanyo lokungasebenzi
Ukunyibilisela kwe-hydroxypropyl methylcelcelgalose yenye iparamitha ephambili yokugqiba umgangatho wayo. Imveliso kufuneka inyibilikiswe ngokulula emanzini kwaye ingabizi iipumps okanye i-gels. Umgangatho ophezulu we-hydroxypropyl methylcelcelcelose firmy kufuneka inyibilikiswe ngokukhawuleza nangokulinganayo.
Ukwenza uvavanyo lomhlaba, nyibilikisa inani elincinci lemveliso emanzini kwaye uvuse isisombululo kude kuchithwe ngokupheleleyo. Isisombululo kufuneka sicace kwaye sikhulule kwi-phumela okanye kwi-gels. Ukuba imveliso ayinyibiliki ngokulula okanye i-tumps okanye i-gels, inokuba luphawu lomgangatho olihlwempu.
Ukuqukumbela, i-hydroxypropyl methylcelcelgalose yinto ebalulekileyo esetyenzisiweyo kumashishini ahlukeneyo. Ukuze kuqinisekiswe umgangatho ophezulu wemveliso, i-viscosity, into enokufakwa endaweni yovavanyo lwezomlomo lwenziwa. Ezi mvavanyo ziya kunceda ukuqonde ngokucacileyo iimpawu zemveliso kwaye zincede ukwahlula umgangatho wayo. Umgangatho ophezulu we-Hydroxypropyl Methylcelcelcelsulose unobungqina obungaguqukiyo, inqanaba eliphezulu lokufakelwa, kunye nokunyibilikisa ngokukhawuleza nangokufanayo emanzini.
