Imiterere yiterambere rya tekinoroji ya HPMC nuburyo bwa hydroxypropyl methyl selulose mubushinwa

Hydroxypropyl methyl seluloseHPMCkugeza ubu umusaruro wimbere mu gihugu urashyirwa imbere hamwe na tekinoroji yuburyo bwa tekinoroji, iri koranabuhanga rihagarariwe n’ikigo cy’ubushakashatsi n’inganda cya wuxi cy’ubushakashatsi mu ishami ry’ubushakashatsi mu Bushinwa mu myaka ya za 70, ibyagezweho mu bushakashatsi hashingiwe ku kuzamurwa mu ntera, umwimerere ni uburyo bwa gaz uburyo bwa gazi ya etherification, kubera ko ibikoresho bitajyanye n’igihugu cyacu, hanyuma bigakora uburyo bwo gutunganya ibyiciro byamazi ya etherification.

Hydroxypropyl methyl selulose yo mu rugo umusaruro wa HPMC muri rusange ukoresha ipamba itunganijwe nkibikoresho fatizo (bamwe mubayikora nabo batangiye kugerageza gukoresha ibiti byimbuto), hamwe no gusya mu rugo cyangwa gusya mu buryo butaziguye alkalisation yipamba itunganijwe, etherifike ikoresheje binary ivanze kama kama, reaction muri reaction ya vertical. Igikorwa cyo kweza gikoresha uburyo bwigihe gito aho umusemburo wa organic ukurwa mumashanyarazi hanyuma ibicuruzwa bitavanze bigasukurwa hifashishijwe gukaraba no kubura umwuma binyuze muri scrubbers na centrifuges. Gutunganya ibicuruzwa byarangiye hamwe na granulation rimwe na rimwe, muburyo bwo gushyushya (hari nuwabikoze adafite granulation), kumisha no guhonyora uburyo busanzwe, ibyinshi mubitunganijwe bidasanzwe ni ugutinza gusa igihe cyo gutunganya ibicuruzwa (guhita bishonga) gutunganya bitarinze gukumirwa no kubikwirakwiza, kubipakira bikoreshwa muburyo bwintoki.

Uburyo bwicyiciro cyamazi gifite ibyiza bikurikira: ibikoresho byogukora ibikoresho byumuvuduko wimbere ni muto, ibikoresho byubushobozi bwibikoresho bisabwa ni bike, ibyago bito; Nyuma yo gutera inda muri lye,selileirashobora kwagurwa byuzuye kandi iringaniye. Lye ifite gucengera neza no kubyimba selile. Imikorere ya etherification ni ntoya, iherekejwe no kubyimba kimwe kwa alkali selulose, bityo ubwiza bwibicuruzwa biroroshye kugenzura, impamyabumenyi yo gusimbuza hamwe nubwiza bushobora kuboneka ibicuruzwa byinshi, ubwoko nabwo biroroshye kubisimbuza.

Nyamara, iki gikorwa nacyo gifite imbogamizi zikurikira: ubusanzwe reaction ntabwo iba nini cyane, imbogamizi zishingiye ku mibare ziganisha ku bushobozi buke bwo gukora, kugirango tunoze umusaruro, ni ngombwa kongera umubare wa reakteri; Ibicuruzwa bitunganijwe neza kandi bisukuye bikenera ibikoresho byinshi, imikorere igoye, imbaraga zumurimo; Kuberako nta anti-mildew hamwe nubuvuzi buvanze, bikavamo ibicuruzwa bihindagurika neza nibiciro byumusaruro bigira ingaruka; Gupakira muburyo bwintoki, ubukana bwumurimo, igiciro kinini cyakazi; Urwego rwa automatike yo kugenzura reaction iri munsi yicyerekezo cya gaze, bityo kugenzura neza ni bike. Ugereranije nibikorwa bya gaz, birakenewe sisitemu yo kugarura ibintu bigoye.

Hamwe no kunoza hydroxypropyl methyl selileHPMCtekinoloji yumusaruro, ibigo bimwe binyuze muburyo bushya bwo guhanga udushya, uburyo bunini bwamazi ya kettle yatejwe imbere nuburyo busimbuka, kandi bufite ubuhanga bwihariye. Chimie ya Anxin ikoresha inzira yumwimerere ya HPMC, ntabwo inzira yumusaruro yonyine ishyize mu gaciro, ibipimo byo kugenzura imikorere birasobanutse kandi byizewe, gukoresha byuzuye kandi byumvikana gukoresha ibikoresho fatizo nibindi biranga, kandi impamyabumenyi yo gusimbuza ibicuruzwa irasa, reaction irasobanutse neza, igisubizo kiboneye ni cyiza, kandi icyarimwe kugirango habeho ireme ryibicuruzwa. Umurongo utanga umusaruro wa HPMC wimishinga imwe n'imwe yahinduwe byikora, kugirango ugere ku bikoresho byo kugenzura DC Ariko kandi itezimbere ibidukikije kurubuga.
