Luluphi olona tyelelo lufanelekileyo lwe-hydroxypropyl methylcelgulose?

I-HydroxyPOpyl Methylcelcelsulose (HPMC) yi-polymer esetyenziswa ngamanzi asetyenziswa kakhulu kwi-pharmaceuticals, cosmetics, ukutya nokwakhiwa. I-HPMC inemisebenzi yokulawula viscofity, imizila yokuzinzisa, ukuphucula iipropathi zeRheeology kunye nokuthambisa, ke i-vickhosity yipharamitha ephambili kwisicelo.

1. Iimpawu ze-viscosity ze-HPMC
Uhlobo lwe-HPMC luhambelana ngokusondeleyo nobunzima bayo, isidanga sokufakwa endaweni (okt, inqanaba lokufakwa endaweni ye-hydroxypropy kunye namaqela e-methyl), ukugxila kwesisombululo kunye nezinye izinto. Ngokubanzi, okukhulu ubunzima bemolekyuli, ukuphakama kwe-viscofity yesisombululo se-HPMC. Ukongeza, isisombululo se-HPMC esinenqanaba eliphezulu lokufakelwa endaweni yokuba sibe ne-viscofitity ephezulu kuba isidanga esichaphazela ubume be-molecular thein, echaphazela intsebenzo yayo kunye nokusebenza kwalo.

I-viscosity ye-HPMC ihlala ilinganiswe kwiqondo elithile le-Shear esebenzisa i-visment yokuhamba. Kuxhomekeka ekusetyenzisweni kwe-HPMC, ixabiso le-viscofity elifunekayo lahlukile.

2. Iimfuno ze-HPMC Viscofity kwizicelo ezahlukeneyo
Intsimi yamayeza
Kumzi-mveliso wamayeza, i-HPMC ihlala isetyenziselwa ukulungisa amacwecwe, i-capsules, iliso lamehlo kunye namachiza alawulayo. Ukulungiselela amacwecwe kunye ne-capsules, i-HPMC idlala indima ebalulekileyo ekumiselweni kwezisombululo kukhulu njengefilimu yangaphambili kunye ne-tickener.

Ukulungiselela ukukhululwa: Ukulungiswa okulawulwa kweziyobisi kufuna i-HPMC ukuba ne-viscofity ephakathi. Ngokubanzi, umzobo wesisombululo se-HPMC kufuneka ulawulwe phakathi kwe-300 ne-2000 i-MPAFS, enceda ukukhutshwa kwechiza. Ukuba i-vickosity iphezulu kakhulu, ichiza linokukhululwa ngokuthe ngcembe; Xa i-vickosity iphantsi kakhulu, isiphumo esilawulwayo seziyobisi sinokungazinzanga.

Uxinzelelo lweTafile Ngeli xesha, i-vickosity kufuneka ibephakathi kwe-500 ne-1500 i-MPAF yokuqinisekisa ukubambelela okuhle kunye nokusebenza ngokufanelekileyo.

Intsimi yokutya
Kwishishini lokutya, i-HPMC idla ngokusetyenziswa njenge-thi checker kunye ne-emulsifier kwiimveliso ezinjengezixhobo, i-ice cream, kunye neziselo zejusi yeziqhamo. Iimveliso ezahlukeneyo zineemfuno ezahlukeneyo zokubonisa i-HPMC:

Iziselo zejusi zeziqhamo: kwiziselo zejusi yeziqhamo, i-viscosity ye-HPMC kufuneka ilawulwe phakathi kwe-50 ne-300 Mparo. I-viscofity ephezulu kakhulu inokubangela isiselo sokungcamla kakhulu, esingayilungeniyo sokwamkelwa kwabathengi.

I-ice cream: kwi-ice cream, i-HPMC isetyenziselwa ukuphucula ukuthungwa kwayo kunye nokugudla. Ngeli xesha, ixabiso le-viscosity lihlala linokulawulwa phakathi kwe-150 ne-1000 le-MPAF ukuze iqinisekise ukuba i-ice cream inomnqweno ofanelekileyo kunye nolwimi olulungileyo luziva.

Ifildi yokwakha
Kumzi-mveliso wokwakha, i-HPMC ihlala isetyenziswa kwizinto zokwakha ezifana nesamente, i-gypsum nodaka. Indima ye-HPMC kwezi zixhobo ingabandakanyi kwaye iphucule ulwaluko. Uluhlu lwayo lokundwendwela luhlala lubanzi, ihlala ingama-2000 ukuya kwi-10000 Mpando. I-HPMC kolu luhlu inokuphucula ngokufanelekileyo ukusebenza kwezinto zokwakha, njengokuphucula ugcino lwexesha lokuvula kunye nokwandisa ixesha lokuvula.

Intsimi ye-cosmetic
Kwintsimi ye-cosmetic, i-HPMC ihlala isetyenziswa ekuqulunqweni kweemveliso ezinjengeengubo, i-crispoos, i-shamps, i-gessoos, i-vills, i-vills, i-1000 ukuya kwi-3000 Mpando. UVenkile okuphezulu kakhulu kunokubangela ukusetyenziswa okungalinganiyo kwemveliso, echaphazela amava omsebenzisi.

I-3. IZINTO EKUFUMANELEKILEYO I-VPMC
Ubunzima bemolekyuli: bukhulu omkhulu ubunzima be-phumc, ixesha elide i-molecular thein, kunye nokupheliswa kwesisombululo. Kwi-HPMC enomthwalo omkhulu wemolekyuli, uVenkile wesisombululo sayo kugxininiso olufanayo luya kuphakama kakhulu kune-HPMC kunye nobunzima obuphantsi be-molecular. Ke ngoko, ukukhetha i-HPMC ngemolekyuli efanelekileyo yiqhosha lokulawula uVeksisity.

Inqanaba lokufakwa endaweni: Isidanga sokufakwa endaweni ye-HPMC, oko kukuthi, inqanaba lokufakwa endaweni ye-hydroxypropy ye-hydroxyl kunye ne-methyl, iya kuchaphazela uVickosity. Inqanaba eliphezulu lokufaka endaweni ihlala lenza iimolekyuli ezizinzileyo le-HPMC ngakumbi, kwaye ukusebenzisana phakathi kweemolekyuli kuyanda, kukhokelela ekunyukeni konyuke.

Ukugxila kwesisombululo: Ukuxinana kwesisombululo se-HPMC kunempembelelo enkulu kwi-viscosity. Ngobuso obuphantsi, uVekyusi weSisombululo se-HPMC uphantsi; Kubuchwephesha obuphezulu, ukusebenzisana phakathi kwamakhonkco eemolekyuli kuyaphuculwa, kwaye uVeksisity uyanda kakhulu. Ke ngoko, kwizicelo ezisebenzayo, uVekyusi wemveliso yokugqibela unokulawulwa ngokuhlengahlengisa uxinzelelo lwe-HPMC.

Izinyibilikiswa kunye neemeko zokusingqongileyo: Ukuluka nokubonisa i-HPMC kunye ne-HPMC kunxulumene ngokusondeleyo nohlobo lweSolvent kunye neemeko zokusingqongileyo (njenge-PH, ubushushu, njl njl). Izinyibilikisi ezahlukeneyo kunye neendlela ezahlukeneyo zobushushu kunye neemeko ze-ps ziya kutshintsha isomba ye-HPMC, ngaloo ndlela ichaphazela uVekyuli wesisombululo.

Uhlobo lwe-HPMC yenye yeeparamitha ezibalulekileyo kwisicelo sayo kwiinkalo ezahlukeneyo. Kwindawo yamayeza, ukutya, ukwakhiwa, i-cosmetics kunye namanye amashishini, i-HPMC kufuneka ilawulwe ngaphakathi kuluhlu oluthile ngokweemfuno zemveliso ezahlukeneyo. Ngokuhlengahlengisa izinto ezinjengokulinganisela kwemolekyuli, isidanga sokufakwa endaweni, uxinzelelo kunye ne-SOLVE ye-HPMC, ukubonwa kwayo kungalawulwa ngokuchanekileyo ukuze kuhlangatyezwane nezicelo zezicelo ezahlukeneyo. Kwinkqubo yemveliso yokwenyani, ukulungiselela i-viscofity yeemfuno ezithile zesicelo sisitshixo sokuqinisekisa umgangatho wemveliso kunye nokusebenza.
