I-Hydroxykyl methyl seluplose (hemc)sisiseko esibalulekileyo se-selle I-HMC ifunyanwa ngokuguqulwa kwemichiza nge-seluplose yendalo njengento engafunekiyo. Isakhiwo saso siqukethe i-hydroxyyl kunye ne-methyl thata, ke ineepropathi ezizodwa zomzimba kunye neekhemikhali kwaye isetyenziswa ngokubanzi kwizinto zokwakha, iikhemikhali, amayeza imihla ngemihla.
I-1. Iipropathi zomzimba kunye neekhemikhali
I-HMC ihlala imhlophe okanye i-good-whider emhlophe okanye igranugules, enyibilikayo kumanzi abandayo ukwenza isisombululo esibonakalayo okanye esincinci se-colbid turbid turbid. Iimpawu zayo eziphambili zibandakanya:
Ukuluka: I-HMC inokuphelisa ngokukhawuleza emanzini abandayo, kodwa inamandla okulala kakubi emanzini ashushu. Ukunyibilisela kunye notshintsho kutshintsha ngotshintsho kwixabiso lobushushu kunye nexabiso le-pH.
Isiphumo sokuqaqamba: I-HMC inamandla amakhulu emanzini kwaye inokunyusa i-viscosity yesisombululo.
Ukugcinwa kwamanzi: Inemisebenzi egqwesileyo yokugcina amanzi kwaye inokuthintela ukulahleka kwamanzi kwizinto.
Ipropathi yokwenza ifilimu: I-HMC inokwenza ifiyunifomu ebonakalayo kumphezulu onobunzima obuthile kunye namandla.
I-Lubrity: Ngenxa yesakhiwo sayo esikhethekileyo semolekyuli, i-HMC inokubonelela nge-ongbring egqwesileyo.
I-2. Inkqubo yemveliso
Inkqubo yemveliso ye-HMC ikakhulu ibandakanya la manyathelo alandelayo:
I-Alkalization: I-Seleose yendalo iphathwa phantsi kweemeko ze-alkaline ukwenza i-alkali sellulose.
Ukuphendula kwe-ether
Unyango lwasemva komphumo olungelulo, luhlanjwe, lulomile, kwaye luqhekezwe ekugqibeleniI-hemciimveliso.
3. Iindawo ezisetyenzisiweyo
. Ingaphucula i-viscofity, ukugcinwa kwamanzi kunye neepropathi ezichasene ne-Antings ezizixhobo zokwakha, zandisa ixesha elivulekileyo, kwaye ke kuphucule ukusebenza kwendlela yokwakha.
. Ukongeza, inokubonelela ngeepropathi zokwenza ifilimu, ezenza ukuba umhlaba wokupeyinta ungaphezulu kwaye ugudileyo.
. Ngenxa yokhuseleko lwayo oluphezulu kunye ne-bicomini, idla ngokusetyenziswa kwiimveliso ezinje ngamahla amehlo, abacocekileyo kunye ne-potions.
.
4. Izibonelelo kunye nokukhusela isisingqongileyo
I-HEMC inobume obuphezulu kunye nezixhobo zokukhusela okusingqongileyo kwaye aziyi kubangela ungcoliseko lwexesha elide kwindalo esingqongileyo. Kwangelo xesha, ayinatyhefu kwaye ayinabungozi, engakhathali kulusu lomntu kunye ne-mucous membrane, kwaye ihlangabezana neemfuno zoKhuseleko lweNdalo oluGqirha kunye nophuhliso oluzinzileyo.
I-5. Amathemba okuthengisa kunye neendlela zophuhliso
Ngokuphuhliswa komzi-mveliso wokwakha kunye nemveliso yemichiza yemichiza yemihla ngemihla, imfuno yentengiso yeHMC iyaqhubeka ikhula. Kwixa elizayo, njengoko abantu benikela ingqalelo ngakumbi kwizixhobo ezinobuhlobo bendalo kwaye bephucula ngakumbi ukusebenza kwemveliso, i-HMC iya kusetyenziswa ngokubanzi kwimimandla eyahlukeneyo. Ukongeza, uphando kunye nophuhliso lweemveliso ze-HMS ezisebenzayo (ezinjengobushushu obunganyangekiyo kunye nohlobo lwethutyana) ziya kukhuthaza isicelo sayo kwimarike ephezulu.
Njengomntu ophumeleleyo kunye nokwenzakala okuphezulu kwe-ether,hydroxykyl methylcelcelce (hemc)Idlala indima ebalulekileyo ekwakhiweni, impahla, amayeza kunye namanye amasimi enemimandla eyahlukileyo yomzimba kunye neekhemikhali. Ngokuqhubela phambili kwesayensi kunye netekhnoloji kunye nokwandiswa kweesilamu zesicelo, i-HMC iya kudlala indima ebaluleke kakhulu kwishishini lanamhlanje kwaye inike inkxaso eyomeleleyo kuphuhliso lwamashishini ahambelana.
