IHydroxypropyl Methylcellulose (HPMC)yi-non-ionic cellulose ether esetyenziswa kakhulu, esetyenziswa kakhulu kwishishini leekhemikhali zemihla ngemihla, ingakumbi kwiimveliso zokucoca ezifana ne-hand sanitizer, i-facial cleanser, i-shampoo, i-shower gel, njl. Imisebenzi yayo ephambili ibandakanya ukuqina, ukumiswa okuzinzileyo, ukufuma okwenza ifilimu, kunye nokuphucula ukuchukumisa.
1. Iimpawu ezisisiseko ze-HPMC
I-HPMC yi-polymer enyibilikayo emanzini eyenziwe nge-cellulose yendalo kwaye iguqulwe ngokweekhemikhali. Ihambelana kakuhle ne-biocompatibility kwaye iyabola. Yi-polymer engeyiyo i-ionic enokunyibilika emanzini abandayo ukuze yenze isisombululo se-colloidal esicacileyo nesiqinileyo. Ngenxa yokunyibilika kwayo okuhle, ukusebenza kwayo kolawulo lwe-viscosity kunye nokhuseleko oluphezulu, isetyenziswa kakhulu kwiindawo zokutya, amayeza kunye neekhemikhali zemihla ngemihla.
2. Indima ephambili ye-HPMC kwi-sanitizer yezandla
2.1. Isiqinisi
Umsebenzi ophambili we-HPMC kukusetyenziswa njengesithambisi. Isibulali-ntsholongwane sesandla sifuna isithambisi esifanelekileyo ukuze kungabi lula ukusilahla, kube lula ukusilawula nokusisebenzisa xa sisetyenziswa ngabasebenzisi. I-HPMC inokunyusa isithambisi semveliso ngokukuko xa isetyenziswa ngamanani aphantsi, okwenza isibulali-ntsholongwane sesandla sibe neempawu ezifanelekileyo ze-rheological, siphucula ukuchukumisa kwayo kunye namava omsebenzisi.
2.2. Izinto ezizinzisa izinto kunye neearhente ezimisayo
Izicoci zezandla zinokuba nezinto ezahlukeneyo ezifana neeoyile ezibalulekileyo, izithako zokulwa neentsholongwane, iinxalenye ze-microcapsule okanye ii-pearlescent agents. I-HPMC inamandla okuqina kwe-emulsification kunye neempawu zokuxhoma, ezinokuthintela ezi zinto ukuba zingabi namacala okanye zingene, kwaye ziphucule uzinzo kunye nokufana kwezixhobo zokucoca izandla.
2.3. Phucula ukutyibilika kunye namava okusebenzisa
Ngenxa yeempawu ze-pseudoplastic fluid zesisombululo se-HPMC (ukunciphisa ukucheba), sinoburhabaxa obuphezulu phantsi kwamandla aphantsi okucheba, kodwa uburhabaxa buyancipha xa umsebenzisi ecinezela aze akhuhle, nto leyo eyenza kube lula ukuyisebenzisa ngaphandle kokushiya imvakalelo yokunamathela. Olu phawu luhambelana kakhulu nokubekwa kwemveliso kwezicoci zezandla njenge "kulula ukuzisebenzisa kwaye kukhululekile ukuzisebenzisa".
2.4. Ukwenziwa kwefilimu kunye nokufumisa
I-HPMC ineempawu zokwenza ifilimu kwaye inokwenza ifilimu encinci enomoya ofanelekileyo kumphezulu wesikhumba, nto leyo edlala indima ekukhuseleni nasekuvaleni amanzi. Ingaphucula ukutyeba kwesikhumba kwaye incede ekunciphiseni ukurhawuzelelwa ziisepha eluswini. Yenye yezithako zokufumisa ezisetyenziswa kakhulu kwiimveliso zokucoca ezithambileyo.
2.5. Phucula inkangeleko yemveliso
Ukukhanya okuphezulu yeyona nto ithengiswa kakhulu kwi-sanitizer yezandla. Emva kokuba i-HPMC inyibilikile, yenza isisombululo esicacileyo nesicacileyo, esingayichaphazeli imbonakalo yemveliso. Ingasetyenziswa neearhente ze-pearlescent ukuphucula isiphumo sokubonakala kunye nokuphucula imvakalelo ephezulu yemveliso.
3. Indlela esetyenziswa ngayo i-HPMC kwi-sanitizer yezandla
Kwifomyula yesanitizer yesandla, i-HPMC idla ngokufakwa kwimo yempuphu. Ukuqinisekisa ukuba inyibilike ngokupheleleyo kwaye kuthintelwe ukuhlangana, kucetyiswa ukuba uyisasaze emanzini abandayo kwaye uyixube kakuhle, uze uyifudumale ukuze kukhawuleziswe inkqubo yokunyibilika. Isixa esisetyenziswa rhoqo sokongeza yi-0.1% ~ 0.8%, kuxhomekeke kwinqanaba le-viscosity elifunekayo kunye nesiphumo sokusebenzisana kwezinye izithako kwifomyula.
4. Iingenelo zokusebenzisa i-HPMC
Ikhuselekile kwaye ayicaphukisi: I-HPMC yi-non-ionic cellulose derivative, ayinatyhefu kwaye ayinavumba, ayinakucaphuka kakhulu eluswini nasemehlweni, kwaye ifanelekile kwiimveliso ezisetyenziswa ngabantwana okanye lusu olubuthathaka.
Iyabola: Yinto yendalo ekrwada enobuhlobo nokusingqongileyo, ehambelana nomkhwa wophuhliso lwezithambiso eziluhlaza.
Ukuhambelana okuqinileyo: Ingahambelana kakuhle nee-surfactants ezahlukeneyo, iincasa, izithinteli kunye nezinye izithako, kwaye ayithambekeli ekungazinzini kwefomyula.
Ixabiso liyalawuleka: Xa kuthelekiswa nezinye izithambisi-manzi ezenziwe nge-polymer, i-HPMC ixabisa kancinci kwaye sisisombululo esingabizi kakhulu nesizinzileyo.
5. Amanyathelo okhuseleko kunye nemingeni
5.1. Indlela yokunyibilikisa kufuneka ilawulwe ngokufanelekileyo
Ukuba umsebenzi awulunganga, iingxaki ezinje ngokuhlanganisana kunye nokunganyibiliki ngokwaneleyo kusenokwenzeka ukuba zivele, nto leyo echaphazela umgangatho wemveliso. I-HPMC kufuneka yongezwe kancinci xa ixutywa kwaye inyibilike ngokupheleleyo kubushushu obufanelekileyo.
5.2. Uluhlu oluthile lokuzivumelanisa ne-pH
I-HPMC izinzile xa ixabiso le-pH liphakathi kwe-4 ne-11. Ukuba ifomula ye-sanitizer yesandla ine-asidi enamandla okanye izinto ze-alkali ezinamandla, kufuneka kuqatshelwe ukuzinza kwayo kunye nefuthe lokugcina i-viscosity.
5.3. Uvakalelo lobushushu
Ukuqina kwe-HPMC kuya kuncipha xa kushushu kakhulu. Ukuba ifomula ye-sanitizer yesandla ifuna ukucoca iintsholongwane kubushushu obuphezulu, ukuzinza kwayo kubushushu kufuneka kuvavanywe.
Ukusetyenziswa kwe-HPMCI-sanitizer yesandla ibonisa iimfuno ezimbini zeemveliso zanamhlanje zeekhemikhali zemihla ngemihla "zokusebenza okuphezulu + ukhuseleko oluphezulu". Ayiphuculi nje kuphela ubume kunye nokusebenza kwemveliso, kodwa ikwaqwalasela ukhuseleko lokusingqongileyo kunye nophuhliso oluzinzileyo. Njengoko iimfuno zabathengi zomgangatho weemveliso zokucoca ziqhubeka zisanda, i-HPMC, njengesixhobo esiluhlaza esisebenzayo, esikhuselekileyo nesizinzileyo, iya kudlala indima ebaluleke ngakumbi kwi-sanitizer zezandla kunye nezinye iimveliso zokucoca kunye nokhathalelo lolusu. Kwiinkampani zeekhemikhali zemihla ngemihla, ukusetyenziswa kwesayensi kunye nengqiqo kwe-HPMC akunakuphucula kuphela ukhuphiswano lwemveliso, kodwa kunokunceda ukudala umfanekiso wophawu olunomtsalane ngakumbi.
