Hydroxypropyl methylcelcelcelces

I-HydroxyPOpyl MethylcelcelUlose ye-Polymer eguquguqukayo efumana izicelo ezixhaphakileyo kwimisebenzi kunye neencwadana ezinemifanekiso eyahlukileyo.

1. Intshayelelo kwi-HPMC:
I-HydroxyPOpyl Methylceltulose, iqhelekile njenge-HPMC, yi-Ionic ye-ionic selethe esungulwe kwi-polymer ye-polymer ye-polymer ngothotho lwezinto eziguqulweyo zekhemikhali. Isetyenziswe ngokubanzi kumashishini ahlukeneyo, kubandakanya nolwakhiwo, amayeza, ukutya kunye neemveliso zononophelo lomntu. Kwingubo yangaphantsi kunye nemihlambi, i-HPMC isebenza njengeyona nto ibalulekileyo ekudluliseleni iipropathi ezininzi ezinqwenelekayo.

I-2. Ukulungiswa kwe-RheOOLOGER:
Enye yeendima eziphambili ze-HPMC kwi-carhengs kunye nee-adhescheves kukukwazi ukuguqula iRheeology. Ngokulawula i-viscofity kunye neepropathi zokuhamba, i-HPMC iququzelela isicelo esingcono, qinisekisa ukugubungela iyunifomu kunye nokunamatheza. I-viscofity elawulwa yi-HPMC ivumela ukuba ikhuselwe iKhuphumeneyo kwaye ithintele i-wagmeng okanye ilahle ngexesha lokufaka, kukhokelela kumgangatho wokugqibela kunye nokuphuculwa komgangatho wokugqibela.

3. Ukugcinwa kwamanzi kunye nokutyibilika:
I-HPMC yaziwa ngomthamo wayo ogqwesileyo wokugcina amanzi, oluncedo ngakumbi kwi-cayishini esekwe emanzini kunye nemikhono. Ngokugcina amanzi ngaphakathi kokumiswa, i-HPMC ithintela ukomisa ngaphambi kwexesha, ukuvumela ixesha elivulekileyo kunye nokusebenza. Ngaphezu koko, i-HPMC isebenza njengearhente yokuthambisa, inegalelo kuzinzo kunye nokungqinelana kwengubo kunye nokubulala, ngaloo ndlela kuphuculwe ukusebenza kunye nokukhululeka kwesicelo.

4. Ukuqulunqwa kweFilim kunye ne-adhesion:
Kwingubo, i-HPMC idlala indima ebalulekileyo kulwakhiwo lwefilimu, ekufakeni isandla kuphuhliso lwamanzi oqinileyo kunye nokukhusela. Iipropathi zayo zokwenza ifilimu zenza umqobo okhusela umqobo kwizinto ezizendalo ezifana nokufuma, imichiza, kunye ne-Abrasion. Ukongeza, i-HPMC iphucula i-adhesion ngokukhuthaza ukuntywila okuhlanganisiweyo phakathi kokuthuka / ukunamathela kunye nokuthathwa komgangatho, kuqinisekisa ukuthembeka okuhlala ixesha elide kunye nokunyaniseka okwaneleyo.

5. Ukuphuculwa kokuphumelela kunye nokusasazeka:
Ukongezwa kwe-HPMC kwi-cayings kunye nababukeli kuphucula ukusebenza nokusasazeka, ukwenza isicelo senze ukuba inkqubo isebenze ngakumbi kwaye isebenziseka lula. Ukukwazi kwayo ukuguqula i-viscosity kunye nokulawula ukuhamba nokuhamba kuqinisekisa ukuphathwa lula kunye nokusetyenziswa, kwanakwiimeko ezinzima. Oku kuphumela kwiimfuno ezincitshisiweyo zomsebenzi kunye nokwandisa imveliso, ukwenza i-HPMC ibe yinto ebaluleke kakhulu kuphuhliso lokuqulunqwa.

I-6. Ukukhutshwa okulawulwa kunye nobomi beshelheli eyandisiweyo:
Kwizicelo ezithile ezinamathele, ezinje ngoxinzelelo olubuthathaka (i-PSS), i-HPMC inokusetyenziselwa ukulawula iipropathi zokukhupha kunye nokuphucula ubomi beshelsi. Ngokufaka i-HPMC kwifomu ye-PSA, abavelisi banokufumana i-tack enqwenelekayo kunye neepropathi ze-Peel ngelixa uqinisekisa ukuzizinza kwexesha elide kunye nokungenela. Oku kwenza ukuba amachaphaza asekwe kwi-HPMC alungele izicelo ezahlukeneyo apho ulawulo olulawulayo kunye nobomi obugqithisileyo bubalulekile.

I-7. Ukungqinelana nokungahambi kakuhle:
Olunye uncedo lwe-HPMC luhambelana noluhlu olubanzi lwezinye ezongeziweyo kunye nezinto ezingafunekiyo ezisetyenziswayo kwimveliso kunye nababukeli. Oku kusebenza kuquzululo kuvumela iifomuli ukuba zisebenzele ukwenziwa kweemfuno zomsebenzi othile ngelixa zigcina uzinzo kunye nokungaguquguquki. Nokuba isetyenziswa yedwa okanye ngokudibeneyo nezinye izongezo, i-HPMC inika ukuguquguquka kunye nokuguquguquka kwenkqubo yokuqulunqa, yenza ukuba ibe kukhetho olukhethwayo kwizicelo ezininzi.

I-HydroxyPOpyl Methylcelcellulose (HPMC) yintshabalalo yezinto ezininzi ezininzi ezidlala indima ebalulekileyo kwi-carhes kunye nemikhono. Ukusuka kwi-Rheoology ukuya kwindawo yokugcina amanzi, ukuqulunqwa kwefilimu, kunye nokuphuculwa komthendeleko, i-HPMC ibonelela ngegalelo lezibonelelo ezifaka isandla kwintsebenzo kunye nomgangatho wemveliso. Ukuguquguquka, ukungqinelana, kunye nokusebenza kwempumelelo kuyenza ibe yinto engenakufumaneka kuphuhliso lwenkqubo, evumela ukudalwa kweemveliso zomsebenzi eziphezulu ezilungiselelwe ukuhlangabezana neemfuno ezahlukeneyo kumashishini ahlukeneyo. Njengophando kunye nophuhliso kwizixhobo zenzululwazi ziyaqhubeka nokuqhubela phambili, i-HPMC inokuthi ihlale isithako esiphambili kwi-carhedings kunye neencwadana ezinemisebenzi, ukugqwesa ekusebenzeni kwemveliso.
