I-HydroxypropylMethylcelcelcelcelcebalose (i-HPMC) yi-polymer yokwenziwa esetyenziswa kwimizi-mveliso eyahlukeneyo yemveliso kubandakanya amayeza, cosmetics nolwakhiwo. Yinto engenatyhefu kunye ne-biodegraphid enezikhundla ezibalaseleyo zokugcina amanzi. Nangona kunjalo, kwezinye iinkqubo, i-HPMC inokubonisa ukugcinwa kwamanzi amaninzi, kunokuba yingxaki. Kweli nqaku, sixubusha ngezizathu ezine eziphambili ze-HPMC igcina amanzi kunye nezisombululo ezithile ezinokubakho ukuphelisa ingxaki.
I-1. Ubungakanani be-suricle kunye nenqanaba lokufaka endaweni
Enye yezona zinto zibalulekileyo ezichaphazela ukugcinwa kwamanzi i-HPMC nguBibcala i-subinter kunye nenqanaba lokufaka endaweni (DS). Kukho amabakala ahlukeneyo e-HPMC, nganye nganye ine-DS kunye ne-suricle ubungakanani. Ngokubanzi, inqanaba eliphezulu lokufakwa endaweni ye-HPMC, iphakame kakhulu umthamo wokugcina amanzi. Nangona kunjalo, oku kukhokelela kwi-viscofity ephezulu, echaphazela ukuqhutywa kwezicelo ezithile.
Ngokukwanjalo, ubungakanani be-paricle ikwachaphazela ukugcinwa kwamanzi kwe-HPMC. Ubungakanani bamahlumela amancinci i-HPMC iya kuba nendawo ephezulu yendawo enokubamba amanzi amaninzi, okukhokelela ekugcinweni kwamanzi aphezulu. Kwelinye icala, ubungakanani bomgangatho omkhulu we-HPMC Vumela ukusasazeka okungcono kunye nokuxuba, kukhokelela kuzinzo olungcono ngaphandle kokugcinwa kwamanzi okubonakalayo.
Isisombululo esinokwenzeka: Ukukhetha inqanaba elifanelekileyo le-HPMC kunye nenqanaba eliphantsi lokufaka endaweni yokufakelwa kunye nobungakanani obukhulu obunganciphisa ukugcinwa kwamanzi ngaphandle kokuchaphazela ukusebenza kwesicelo.
I-2. Iimeko zendalo
Iimeko zendalo ezinje ngamaqondo obushushu kunye nokufuma anokuchaphazela kakhulu ukugcinwa kwamanzi kwe-HPMC. I-HPMC inokufumana nokugcina umswakama kwindawo engqongileyo, enokukhokelela ekugcinweni kwamanzi amaninzi okanye ukucotha. Amaqondo obushushu aphezulu akhawuleze akhawuleze ukufumanisa umswakama kunye nokugcinwa, ngelixa amaqondo obushushu asezantsi ayacothisa inkqubo yokomisa, ebangela ukugcinwa komswakama. Ngokukwanjalo, iindawo eziphakamileyo zokufuma zinokubangela ukugcinwa kwamanzi kakhulu kwaye nokubuyiselwa kwe-HPMC.
Isisombululo esinokubakho: Ukulawula iimeko zokusingqongileyo apho kusetyenziswa i-HPMC ekunokunciphisa ukugcinwa kwamanzi. Umzekelo, usebenzisa i-dejumidifiififir okanye i-air conditionet inokunciphisa ukufuma, ngelixa isebenzisa i-fan okanye i-heater inokunyusa inqwelo moya kwaye inciphise ixesha elithatha i-HPMC ukuze yome.
I-3. Ukulungiswa okuxubeneyo
Ukuxuba kunye nokulungiswa kwe-HPMC kungachaphazela neepropathi zayo zokugcina amanzi. I-HPMC ixutywe kwaye igqitywe njani inokuchonga amandla ayo okuqhuba amanzi kunye nenqanaba lokuhamba-rateration. Ukudityaniswa okungalunganga kwe-HPMC kunokubangela ukungcola okanye ukukhonkotha, okuchaphazela amandla okuphatha amanzi. Ngokukwanjalo, ukudibanisa ngaphezulu okanye ukuqhubekeka kunokubangela ukuncitshiswa kwe-paricle ye-paricle, eyonyusa ukugcinwa kwamanzi.
Izisombululo ezinokubakho: Ukuxuba ngokuchanekileyo kunye nokulungisa kunokunciphisa kakhulu ukugcinwa kwamanzi. I-HPMC kufuneka ixutywe okanye idityaniswe ngokupheleleyo ukuqinisekisa ukusasazwa okulinganayo kunye nokuthintela ukwenziwa kweendlela okanye iziqhushumbisi. Ukufikelela ngaphezulu kufuneka kuthintelwe kwaye iimeko zokulungisa zilawulwa ngononophelo.
4. Ifomula
Okokugqibela, ukwenziwa kwe-HPMC ikwachaphazela iipropathi zayo zokugcina amanzi. I-HPMC ihlala isetyenziswa ngokudibeneyo nezinye ezongeziweyo, kunye nokungqinelana kwezi zongezo kuya kuchaphazela ukugcinwa kwamanzi kwe-HPMC. Umzekelo, ezinye iziqwengana okanye i-surfcapes zinokunxibelelana ne-HPMC kwaye inyuse amandla ayo okuqhuba amanzi. Kwelinye icala, iityuwa ezithile ze-inorganic okanye i-acids zinciphisa umda wokubamba amanzi ngokuthintela imikhwa ye-hydrogen.
Izisombululo ezinokubakho: Ukuqulunqwa ngononophelo kunye nokukhethwa kweezongezo ezinokunciphisa ukugcinwa kwamanzi. Ukuhambelana phakathi kwe-HPMC nakwezinye izinto ezongezekiso kufuneka ziqwalaselwe ngononophelo kwaye ifuthe labo ekugcinweni kwamanzi. Ukukhetha izongezelelo ezinefuthe elincinci ekugcinweni kwamanzi kunokuba yindlela esebenzayo yokunciphisa ukugcinwa kwamanzi.
ukuququmbela
Ukuqukumbela, i-HPMC iye yaba yinto ebalulekileyo kumashishini ahlukeneyo ngenxa yepropathi yakhe ebalaseleyo yokugcina amanzi. Nangona kunjalo, kwezinye iinkqubo, ukugcinwa kwamanzi kakhulu kunokuba yingxaki. Ngokuqonda izinto ezichaphazela ukugcinwa kwamanzi kunye nokusebenzisa izisombululo ezifanelekileyo, ukugcinwa kwamanzi i-HPMC kunokuba kuncitshiswe kakhulu ngaphandle kokusebenza.
