Iterambere ry'ikoranabuhanga mu gukora HPMC n'uburyo selulose ya hydroxypropyl methyl cellulose iteye mu Bushinwa

Hydroxypropyl methyl celluloseHPMCKu bijyanye n’umusaruro w’imbere mu gihugu ubu uhabwa umwanya w’ibanze hamwe n’ikoranabuhanga ry’uburyo bw’ingufu z’amazi, iri koranabuhanga rihagarariwe n’ikigo cy’ubushakashatsi n’igishushanyo mbonera cya Wuxi mu Bushinwa mu myaka ya 1970, ubushakashatsi bwagezweho bushingiye ku guteza imbere, icya mbere ni uburyo bwa etherification bwa gaze, kuko ibikoresho bidahuye n’igihugu cyacu, hanyuma hakorwa uburyo bwa etherification bwa liquid phase, Kugeza ubu inzira ya etherification y’uburyo bwa bath ratio ya liquid phase iracyari inzira nyamukuru yo gukora ya bamwe mu bakora ether bazwi cyane ba cellulose.

Umusaruro wa HPMC wo mu rugo ukoresha ipamba itunganyijwe nk'ibikoresho fatizo (bamwe mu bakora ibintu batangiye kugerageza gukoresha impumuro y'ibiti), no gusya mu rugo cyangwa gukoresha alkalizasiyo y'ipamba itunganijwe, etherization ikoresheje solvent ivanze na binary organic, reaction muri reactor ihagaze. Uburyo bwo gutunganya bukoresha inzira y'igihe gito aho solvent y'umwimerere ikurwa muri reactor hanyuma umusaruro ukozwe mu buryo bwa kera ugasukurwa binyuze mu koza kenshi no gusukura amazi binyuze mu byuma bisukura na centrifuges. Gutunganya ibicuruzwa byarangiye hamwe na granulation ihoraho, mu gihe cyo gushyushya (hari n'uruganda rudafite granulation), kumisha no gusya mu buryo busanzwe, inyinshi mu buryo bwihariye bwo gutunganya ibicuruzwa ni ugutinza igihe cyo kunywesha amazi (gushonga vuba) gutunganya nta mildew gukumira no gukwirakwiza, gukoresha uburyo bwo gupakira hakoreshejwe intoki.

Uburyo bwo gukoresha icyiciro cy'amazi bufite ibyiza bikurikira: igitutu cy'imbere mu gikoresho cyo gukora inyigo ni gito, ubushobozi bw'igitutu cy'ibikoresho ni buke, ingaruka ni nto; Nyuma yo gutera inshinge muri lye,seluloseishobora kwaguka neza kandi ikagira alkali ingana. Lye ifite uburyo bwiza bwo kwinjira no kubyimba kwa cellulose. Reactor ya etherification ni nto, hamwe no kubyimba kwa alkali cellulose, bityo ubwiza bw'umusaruro biroroshye kugenzura, urwego rwo gusimbuza n'ubukana bishobora kuboneka ibicuruzwa bimwe, ubwoko nabwo biroroshye gusimbuza.

Ariko, iyi gahunda ifite kandi ingaruka mbi zikurikira: icyuma gitera amashanyarazi ubusanzwe ntabwo ari kinini cyane, imbogamizi z'imibare zituma ubushobozi bwo gukora bugabanuka, kugira ngo umusaruro urusheho kwiyongera, ni ngombwa kongera umubare w'ibyuma bitera amashanyarazi; Ibicuruzwa byatunganyijwe kandi byejejwe bikenera ibikoresho byinshi, imikorere igoye, imbaraga z'abakozi; Kubera ko nta buryo bwo kurwanya ubwivumbure n'ubukonje bukoreshwa mu kuvura ibiyobyabwenge, bigatuma ubwivumbure bw'umusaruro bugumaho kandi ikiguzi cyo gukora kikagira ingaruka; Gupakira hakoreshejwe intoki, imbaraga z'abakozi, ikiguzi kinini cy'abakozi; Igipimo cyo kugenzura imikorere y'ibikoresho mu buryo bwikora kiri hasi ugereranyije n'icyiciro cya gazi, bityo ubushishozi bwo kugenzura ni buke. Ugereranyije n'icyiciro cya gazi, hakenewe uburyo bwo kugarura amashanyarazi bugoye.

Hamwe no kunoza hydroxypropyl methyl cellulose yo mu rugoHPMCIkoranabuhanga mu gukora, ibigo bimwe na bimwe binyuze mu guhanga udushya twigenga, uburyo bwa kettle nini bwakozwe ku buryo bwihuse, kandi bufite imiterere yabwo bwite ya tekiniki. Ubutabire bwa Anxin bukoresha inzira ya mbere yo gukora HPMC, ntabwo ari inzira yo gukora gusa ikwiye, ibipimo byo kugenzura imikorere ni byiza kandi byizewe, ikoreshwa ryuzuye kandi rikwiye ry'ibikoresho fatizo n'ibindi biranga, kandi urwego rwo gusimbuza ibicuruzwa ni rumwe, igisubizo ni cyiza rwose, ubwisanzure bw'umuti ni bwiza, kandi icyarimwe kugira ngo habeho ireme ry'umuti uhamye. Umurongo w'umusaruro wa HPMC w'ibigo bimwe na bimwe wahinduwe mu buryo bwikora, kugira ngo hagerwe ku bisabwa mu kugenzura DCS by'igikoresho, ibikoresho birimo amazi, ibikoresho fatizo bikomeye bishobora gukoreshwa mu gupima no kongeramo sisitemu ya DCS neza, kugenzura ubushyuhe n'umuvuduko mu nzira yo gukora byose bigerwaho mu kugenzura DCS mu buryo bwikora no kugenzura kure. Mu bijyanye no gukora neza, kwizerwa, gutuza no kurinda umutekano w'umusaruro, biragaragara ko byarushijeho kuba byiza ugereranije n'uburyo gakondo bwo gukora, butazigama abakozi gusa, bugabanya imbaraga z'abakozi, ahubwo bunanoza ibidukikije byo gukorera aho bikorerwa.
