Nibihe bintu bigira ingaruka nziza kuri hydroxypropyl methyl selulose?

Mu nyubako ya insulari yububiko hamwe nifu ya putty, ingano ya hydroxypropyl methylcellulose isukuye igira ingaruka itaziguye mubwiza bwubwubatsi, none nikihe kintu kigira ingaruka kumyera ya hydroxypropyl methylcellulose? Kugufasha gusubiza iki kibazo uyumunsi.

Mubikorwa byo kubyara hydroxypropyl methylcellulose, ogisijeni isigaye mu isafuriya ya reaction izatera kwangirika kwa hydroxypropyl methylcellulose no kugabanya uburemere bwa molekile. Nyamara, umwuka wa ogisijeni usigaye ni muto, ntabwo rero bigoye kongera guhuza molekile zacitse. Igipimo nyamukuru cyo kwiyuzuzamo hamwe na hydroxypropyl ibifitanye isano ikomeye, inganda zimwe zishaka kugabanya igiciro nigiciro, ntizifuza kunoza ibikubiye muri hydroxypropyl, bityo ubwiza ntibushobora kugera kurwego rwibicuruzwa bisa n’amahanga.

Igipimo cyo gufata amazi ya hydroxypropyl methylcellulose na hydroxypropyl nacyo gifite umubano ukomeye, kandi kubikorwa byose, hydroxypropyl methylcellulose nayo igena igipimo cyo gufata amazi ya hydroxypropyl methylcellulose. Ingaruka ya alkalisation, igipimo cya chloromethane na okiside ya propylene, ubunini bwa alkali hamwe n’amazi y’ipamba itunganijwe byose bigena imikorere yibicuruzwa.

Ubwiza bwibikoresho fatizo, ingaruka za alkalisation, igenzura ryibikorwa, igipimo cya solvent ningaruka zo kutabogama, byose bigena ubwiza bwa hydroxypropyl methyl selulose, hydroxypropyl methyl selulose yakozwe kugirango ishonga nyuma nkamata ari ibicu cyane, bimwe byera byamata, bimwe byumuhondo, bimwe bisobanutse kandi bisobanutse. Niba ushaka kubikemura, hindura uhereye ku ngingo zavuzwe haruguru. Rimwe na rimwe, aside irike irashobora kugira ingaruka zikomeye ku kwanduza, aside irike ikoreshwa neza nyuma yo kuyungurura, ingaruka nini cyangwa reaction itera ni imwe, igipimo cya sisitemu gihamye (ibinyabuzima bimwe na bimwe, ibintu ntabwo bihagaze neza, nko kugarura ibishishwa), mubyukuri, ibintu byinshi bigira ingaruka. Hamwe noguhagarara kwibikoresho nigikorwa cyabakozi bahuguwe, ibicuruzwa byakozwe bigomba kuba bihamye. Ihererekanyabubasha ntirishobora kurenga ± 2%, kandi uburinganire bwo gusimbuza itsinda ryabasimbuye bugomba kugenzurwa neza. Gusimburanya kimwe, kohereza bigomba kuba byiza.

Kubwibyo, ubuziranenge bwibicuruzwa bugenwa nibikoresho fatizo, tekinoroji yumusaruro, nibindi bintu. Gusa kugenzura gukomeye kuva kumpera imwe kugeza kumpera birashobora gutanga ibicuruzwa bifite ireme ryiza.
