Ngwa nke hydroxypropyl methylcellulose na-ewu na igwe gbawara ngwa ngwa

Hydroxypropylmethylcellulose

A na-eji hydroxypropylmethylcellulose (HPMC) eme ihe n'ọtụtụ ebe na mmepụta ihe owuwu yana maka macroflora, enwere ike iji cellulose mee ihe dị ka onye na-azụ azụ, nchebe, thickener na slime. N'ime ngwa agha akọrọ akọrọ a na-ejikarị na mpụta mgbidi, ngwa agha mkpuchi ọkụ, ngwa agha na-edozi onwe ya, nrapado elu ịnyịnya akọrọ, ngwa ngwa viscose tile, putter powder, mpụta mgbidi, ngwa agha mgbochi mmiri, na ihe mgbawa, cellulose ether na-arụ ọrụ dị mkpa. Ọrụ dị mkpa, ọ bụ plasta sistemu mmiri na-adabere na mmiri, ọchịchọ mmiri, ike, nke na-agbagharị ma na-arụpụta ihe dị mkpa.

N'ozuzu, HPMC na-eji na-emepụta pulp na a mgbe nile viscosity nke 100,000 viscose, nke a na-ejikarị na ngwaahịa ndị dị otú ahụ dị ka akọrọ pulp, diatom pulp maka mmepụta nke pulp, nke mejupụtara 200,000 viscous pulp na ndị ọzọ ụlọ ihe dị ka akọrọ ngwọta. silica Algae cellulose, nke a na-ejikarị ya na 400,000 pulp nnyapade, nwere ike ịsacha ma mee ka ọ dịkwuo mma.

Ngwa nke HPMC n'ime igwe na-agbawa ngwa ngwa

Ka anyị na-ejegharị na usoro niile nke otu esi arụ ihe ngwọta n'elu ụgbọ elu: mix, pump, and swab.

Nke mbụ, anyị ga-ahụrịrị na na ndabere nke usoro ezi uche dị na ya na ihe eji emegharị ya, ihe mgbakwunye mejupụtara igwe sandblasting ngwọta na-arụ ọrụ dị ka ngwọta kachasị mma, tumadi iji melite arụmọrụ nke mgbapụta ahụ.

Ya mere, dị ka a na-achị, ihe mgbakwunye jikọtara maka igwe na-agbawa ọkụ na-agụnye ngwakọta nke nchebe na mgbapụta slurries. Na hydroxypropyl methylcellulose nwere ike ọ bụghị naanị na-amụba viscosity nke ájá, kamakwa mma ya fluidity, si otú ibelata ohere nke iche na hydrophilic phenomena. Mgbe ndị na-arụ ọrụ na-emepụta nchikota nke ngwa agha na-agba aja aja, ha kwesịrị ịgbakwunye ọtụtụ ihe nkwụsi ike n'oge, ma n'otu oge ahụ na-ebelata usoro ire ere.
