Hydroxypropyl methyl seluplose (hpmc), isixhobo esiyiloisellulose, inokuba yi-cotton yekotoni okanye i-pulp yenkuni. Kuyimfuneko ukuyilahla ngaphambi okanye ngexesha lenkqubo yokuphumelela. I-pulverser yenziwa ngamandla omatshini. Destroy the aggregated structure of cellulose raw materials to reduce crystallinity and polymerization degree and increase its surface area, thereby improving the accessibility and chemical reaction ability of the reagents to the three hydroxyl groups on the cellulose macromolecular glucose ring base.
Hydroxypropyl methyl seluplose (hpmc)isetyenziswa njengendawo engacacanga ukuba ivelise ioyile, enokukuqaphela ukusetyenziswa kweswekile yonke, ukuphucula izinga lokusetyenziswa kwezinto eziluhlaza, ukunciphisa inani elivisayo lomhluzi we-boriment, kwaye unciphise iindleko zonyango lwamanzi amdaka. Iimpawu zeI-Methyl Selelosezilungele ukusebenza kwe-batch, i-fed-batch kunye neenkqubo zokuqhubela phambili, zithintele uthotho lweengxaki ezinje ngokulawula ukwakhiwa kwenqanaba eliphakathi neli-dilution; Kwangelo xesha, kuya kuba negalelo kumgaqo wenkqubo yobuso. Kuba iipropathi zehydroxypropyl methyl seluplose (hpmc)ziyafana nezinye ii-arhente zefilimu, i-thicker, i-tickener, i-enulssifier enamacandelo ase-Latex kunye ne-wilsin eshukumayo, esenza ukuba kube lula ukwenza i-arasings elungileyo, ukulinganisa Iipropathi kunye nonamatheliso, kwaye uphucule uxinzelelo lomphezulu, uzinzo kwi-acid kunye ne-alkali, kunye nokuhambelana nemiphetho yensimbi.
Hydroxypropyl methyl seluplose (hpmc)inefuthe elihle njenge-thi cokener ye-Polyviny ye-Polyviny ye-Polyviny ye-Polyviny. Inqanaba lokufaka endaweniI-Selersese Etherinyukile, kwaye ukuxhathisa kwiibacteria kunye nokhukuliseko kuyaphuculwa.
Nangona umgaqo we-etherhesication synthesic ye-hydroxypropyl methylcelsele (i-HPMC) ayinzima, i-alkalition, i-alkalition. Iindawo ezahlukeneyo ze-etheriya, ukubuyela kwimeko yesiqhelo, ukwahlulwa kwe-Centrifugal, ukuhlamba kunye nokumisa kubandakanya inani elikhulu leetekhnoloji eziphambili kunye nolwazi olutyebileyo.
Ngeentlobo ezahlukeneyo zeemveliso, indawo nganye ineemeko zolawulo lwamva nje, njengamaqondo obushushu, ixesha, uxinzelelo kunye nolawulo lokuhamba kwezinto. Izixhobo ezincedisayo kunye nezixhobo zolawulo zisisiqinisekiso esinokuthenjwa nesiyingenelo kwimveliso enemveliso ephantsi kunye nemveliso ethembekileyo.
Iimpawu zeMveliso zehydroxypropyl methyl seluplose:
I-1. Iipropathi: Le mveliso ingumgubo omhlophe, kwaye ingenanto, engenaxabiso kwaye ingenabungozi.
2. Ukugcinwa kwamanzi: kuba le mveliso inokufumana amanzi amaxesha aliqela elinzima kunawo. Gcina ugcino oluphezulu lwamanzi, iGypsum, ipeyinti kunye nezinye iimveliso.
3. Le mveliso inokupheliswa emanzini abandayo ukwenza i-slicvaus ye-SLICUS ebonakalayo.
I-4. Ukuchithwa kwezinyibilikisi ze-organic: kuba iqulethe inani elithile lemidlalo ye-hydrophobic, le mveliso inokupheliswa kwezinye izinyibilikisi ezisebenzayo, kwaye inokuchithwa kwiinyibilikisi ezixutywe namanzi.
5. Ukunganyangeki kwetyuwa: Kuba le mveliso iyinto engeyiyo i-ionic kwaye ingeyiyo i-polyectrolyte, isizinzileyo kwizisombululo ze-aces ze-artic okanye ii-onctroytes zezinto eziphilayo. Kwimeko ye-electrolyte kakhulu, inokubangela ukungcwatywa okanye ukuchama.
I-6. Umsebenzi womphezulu: Isisombululo se-ACTEAGOF LEMveliso sinomsebenzi womphezulu.
