Umxokelelwane ongekho mthethweni, odlala indima ephambili ekuphuculeni intsebenzo yokwakha ubufa oxubeneyo, iiakhawunti ngaphezulu kwe-40% yexabiso lezinto eziphathwayo kumxube oxubeneyo. Uninzi lwentengiso yasekhaya kubonelelwa ngabavelisi bamanye amazwe, kwaye imithamo yereferensi yemveliso ikwanikezelwa ngabathengisi. Ixabiso lodaka oluxubileyo luhlala luphakamile, kwaye kunzima ukwenzela ukwehla udaka oluqhelekileyo kunye nokufakelwa kwendawo enexabiso elikhulu kunye noluhlu olubanzi. Iimveliso zokuphela kwemakethi eziphezulu zilawulwa ziinkampani zangaphandle, kwaye abavelisi abaxubeneyo banomxubo baneenzuzo ezisezantsi kunye nokufikeleleka kwexabiso eliphantsi; Ukusetyenziswa kwe-temisoxting acks ecwangcisiweyo kunye nophando olujolise kulo, kwaye ngokubonayo kulandela iifomula zangaphandle. Apha, yintoni esabelana nawe yile, injani indima ye-hydroxypropyl methylcelcelcelose kubuchwephesha obuqhelekileyo?
I-HydroxyPOpyl Methylcelcelgalose yintlobo ngeentlobo zeselfowuni kwaye isetyenziselwe ukusetyenziswa ngokukhawuleza kwiminyaka yakutshanje. I-HydroxyPOpyl Methylcelcelsele yenziwa nge-cotton ye-alkali, esebenzisa i-propylene oxide kunye ne-propyl oxide kunye neearhente ze-e-Ionic ze-Ether exubeneyo ezenziwe ngothotho lweempendulo. Inqanaba lokufakwa endaweni yi-1.2 ~ 2.0. Iipropathi zayo zahlukile kuxhomekeka kumyinge we-platexyl kunye nomxholo we-hydroxypropy. Iimpawu ze-HydroxyPOpyl Methylcelgaloe ngolu hlobo lulandelayo:
I-1. I-HydroxyPOpyl Methylcelceltulose inyibilika ngokulula emanzini abandayo, kwaye iya kudibana nobunzima ekupheliseni amanzi ashushu. Kodwa iqondo lokuhlaselwa layo lokuhlaselwa kwamanzi ashushu liphezulu kakhulu kune-methyl seluplose. Ukunyibilisela emanzini abandayo kuyaphuculwa kakhulu xa kuthelekiswa neMethyl Selelose.
2. UVenkile ye-HydroxyPOpyl Methylcelcelose inxulumene nobunzima bayo. Ukukhululeka ubunzima bemolekyuli, ukuphakama kwe-viscofity. Ubushushu buchaphazela i-viscofity yayo, njengoko amaqondo obushushu ayanda, i-viscosity ihla. Nangona kunjalo, impembelelo yophawu lwayo oluphezulu kunye neqondo lobushushu lingaphantsi kune-methyl sellulose. Isisombululo sayo sizinzile xa sigcinwe kubushushu begumbi.
3. Ukugcinwa kwamanzi kwe-Hydropyl I-Methylcelcelgalose ixhomekeke kwixabiso lokudibanisa, i-viscofity, njl njl., Njl njl.
I-4. I-HydroxylCopyl Methylcelcelcelose iZinzile kwi-Acid kunye neAlkali, kunye nesisombululo se-ALKALI, kunye nesisombululo sayo esizinzileyo kuluhlu lwe-pH = 2 ~ 12. I-Caustic Soda kunye namanzi e-lime anempembelelo encinci ekusebenzeni kwayo, kodwa uAlkali unokukhawulezisa ukupheliswa kwayo kwaye unyuke kancinci. I-HydroxyPOpyl Methylcelcelcelose iZinzile kwi-SECTs eqhelekileyo, kodwa xa uxinzelelo lwesona sityibilili liphezulu, i-viscosity ye-hydroxypropyl methylcelses isisombululo sithanda ukunyuka kwesisombululo.
I-5. I-HydroxylCopyl Methylcelcelgalose inokudityaniswa ne-polymer ye-wala-follmer ukwenza iyunifomu kunye nesisombululo esiphezulu se-viscofity. Ezinjenge-polyvinyl utywala, i-starch ether, i-gum yemifuno, njl.
6. I-HydroxylCopyl Methylcelcelculose inomsindo ongcono kune-methylceluplup
7. Ukubiyela kwe-hydroxypropy ye-hydroxylceluplose yomhlaba iphakamile kune-methylceluplupluplose.
