Umsebenzi wokwakha:Ingaphucula ukungasebenzi kodaka, kwandise ixesha elivulekileyo, lenze kube lula ukusebenza ngexesha lokwakha.
I-2. I-HydroxyEtheetheetheetheetheetheetheetheetheese Teluplose (Hec)
I-HydroxyEtheetheetheetheetheetheetheetheetheetheethee i-ether sisisele i-ether ye-Eledroxyyl amaqela angeniswe kwimolekyuli eselselose. Iimpawu zayo eziphambili zibandakanya:
Umoya wobuchule:I-hec inokunyibilikisa ngokukhawuleza emanzini ukwenza isisombululo se-viscous esibonakalayo.
Ukutyibilika:Xa kuthelekiswa ne-MC, i-HEC inefuthe elinamandla kwaye idla ngokusetyenziswa ngezinto zokwakha ezifuna i-ratheemology ephezulu kunye ne-viscofity.
Ukugcinwa kwamanzi:I-hec igcinwe kakuhle amanzi kwaye inokugcina i-turdor emanzi kangangexesha elide ukuthintela udaka ukuba luphule kwaye luqhekeke.
Ukumiswa:I-hec inokuphucula amandla okumiswa kwamasuntswana aqinileyo kwi-slicry ukunqanda ukuhambisa i-sediment okanye i-suricule.
Anti-Shudu:I-HEC inezilungelelaniso ezifanelekileyo ukuya kubushushu obuphantsi kwaye zinokusetyenziswa kwiindawo ezibandayo.

I-Hydroxypropyl Methylcelcelcelose sisisele i-ete i-selsulose efunyenwe ngokutshintsha iqela le-hydroxyl kwimolekyuli ye-selselose eneqela le-hydroxypropy. Iimpawu zayo eziphambili zibandakanya:
Umoya wobuchule:I-HPMC inokunyibilikisa ngokukhawuleza emanzini ukwenza i-colloid ebonakalayo enophawu oluphezulu.
Ukutyibilika kunye nozinzo:I-HPMC inefuthe eliqaqambileyo. Ngelixa wanyusa i-viscofity yokwakha, inokugcina uzinzo kodaka, inciphise ukususwa kwezinto.
Ukunganyangeki kobushushu obuphezulu:Xa kuthelekiswa ne-MC kunye ne-HEC, i-HPMC inonyamezelo omeleleyo kumaqondo obushushu aphezulu, ngoko ke kufanelekile ukwakhiwa kwiindawo ezithile zobushushu obuphezulu.
Ukunganyangeki kwe-hydrolysis:I-HPMC inozinzo oluhle lokufumana i-hydrolysis kwaye ilungele ukusetyenziswa kwiindawo ezinomswakama.
4. Ipropathi ebanzi ye-selsulose
Ukusetyenziswa kwe-selsulose talsund kwishishini lokwakha ikakhulu kuxhomekeke kwiipropathi zalo ezahlukeneyo, ngakumbi kwiimveliso ezinje ngodaka, iingubo, kunye nokubulala. Oku kulandelayo ziipropathi ezininzi eziqhelekileyo ze-seluplose een:
Ukutyibilika:I-seluplose en 'iphucula indlela yokusebenza kwengubo okanye i-fert ngokwandisa i-viscomosity yolwelo, kwaye ibe nolwelo oluhle kunye nexesha.
Ukugcinwa kwamanzi:Kwindawo yokuthamba nezinye izinto zokwakha, ukugcinwa kwamanzi kunceda ukukhusela amanzi ekufumeni ngokukhawuleza, kuqinisekisa ubumbisi ngexesha lokwakha, kwaye wandisa ixesha lokusebenza.
Ukunganyangeki:I-Telupelose Ether inokuphucula ngokufanelekileyo ukunganyangeki kwezinto kwaye kuncitshiswe imingxunya ebangelwe kukuncipha kowomisayo okanye amakhosi angaphandle.
Ulondolozo:Ukusetyenziswa kwe-etelsese Ether kunokuphucula ukudalwa kokwakha izixhobo kunye nokuphucula ukusebenza kwabasebenzi.
I-anti-sediment:Ngakumbi ulwakhiwo lwamanzi, i-Selesese I-Ether inokunciphisa ukuntywila kwezinto eziqinileyo kwaye igcine ukungqinelana kwesilayidi.
I-5. Amasimi esetyenziswayo
I-Ether ye-Ibarsulose yeBanga laseKhaya isetyenziswa ikakhulu kwezi ntlobo zilandelayo zezinto zokwakha:
Udaka:I-Seleulose Ether inokuphucula ukusebenza, ukugcinwa kwamanzi, ukunganyangeki kunye nokuchasana nodaka lodaka, kwaye kusetyenziswa kakhulu ngorhatya, udaka lokuhlaselwa, udaka, udaka oluhle, unyango, udaka oluhle, luhlalulwa, njl njl.
Ipeyinti:I-Teluplose Ether inokusetyenziswa njenge-thi checkener kwaye isasazeke ekuphuculeni ulwelo kunye nokunamathela kwipeyinti.
