Starch ether (nke a makwaara dị ka polima lubricant)

Echiche: Ụdị starch na-abụghị ionic nke a kwadebere site na mmeghachi omume etherification nke propylene oxide na starch n'okpuru ọnọdụ alkaline, nke a makwaara dị ka starch ether. Ngwa ngwa bụ tapioca starch. N'ime ha, ọdịnaya hydroxypropyl bụ 25%, nke bụ anti-thixotropic. N'ihi obere viscosity ya, elu hydrophilicity, ezigbo fluidity, adịghị ike retrogradation na elu kwụsie ike, ọ na-ọtụtụ ebe na-ewu na mma ụlọ ọrụ, dị ka ewu akọrọ ntụ ntụ, plasta, nkwonkwo nrapado na ndị ọzọ na-anọpụ iche Na alkaline mejupụtara ihe, melite n'ime ime. nhazi nke ihe onwunwe, ma nwee ezigbo ndakọrịta na ihe mgbakwunye dị na ya, nke mere na ngwaahịa ahụ na-eguzogide ọgwụ na-ekpo ọkụ na-ekpo ọkụ, mgbochi sag, ma na-eme ka arụ ọrụ na ịrụ ọrụ na-arụ ọrụ dịkwuo mma.

A na-eji ether starch emezigharị eme ihe na-ewu, tumadi maka ndim na mgbochi sagging, na cellulose ether bụ nke kachasị maka njide mmiri, ya mere a na-eji starch ether eme ihe na cellulose ether;

Ọ nwere ike ịgbanye ma na-ejigide mmiri, na-emepụta uru ndị na-akwado ya (dị ka usoro ahụ si dị, belata ego HPMC ihe dị ka 30% ma dochie ya na starch ether iji mee ka arụmọrụ ngwaahịa dịkwuo elu)
