Kuchena kwehydroxypropyl methylcellulose mukuvaka insulation mortar uye putty powder kunokanganisa zvakananga kunaka kwekugadzirwa kweinjiniya, saka ndezvipi zvinhu zvinokanganisa kuchena kwehydroxypropyl methylcellulose? Regai ndikupindurei mubvunzo uyu.
Mukugadzirwa kwehydroxypropyl methylcellulose, okisijeni yakasara iri mu reactor inokonzera kuora kwehydroxypropyl methylcellulose uye kuderedza huremu hwemolecular, asi okisijeni yakasara ishoma, chero bedzi zvisiri zvakaoma kubatanidza zvakare mamorekuru akaputsika Njodzi. Chinonyanya kukosha chekuzara kwemvura chine chekuita nehuwandu hwehydroxypropyl. Mamwe mafekitori anongoda kuderedza mutengo nemutengo, asi haadi kuwedzera huwandu hwehydroxypropyl, saka mhando haigone kusvika padanho rezvigadzirwa zvakafanana zvekunze.
Mwero wekuchengetedza mvura wehydroxypropyl methylcellulose une hukama hwakanaka nehydroxypropyl, uye pakuita kwese kwekuita, hydroxypropyl inosarudzawo mwero wekuchengetedza mvura wehydroxypropyl methylcellulose. Mhedzisiro yealkalization, chiyero chemethyl chloride nepropylene oxide, kuwanda kwealkali uye chiyero chemvura nedonje rakacheneswa zvese zvinosarudza mashandiro echigadzirwa.
Hunhu hwezvinhu zvakagadziriswa, mhedzisiro yealkalizing, kudzora chiyero chemaitiro, chiyero chezvinonyungudutsa uye mhedzisiro yekusagadzikana zvese zvinosarudza hunhu hwehydroxypropyl methylcellulose, uye imwe hydroxypropyl methylcellulose inogadzirwa kuti inyungudike. Mushure mezvo, yakanga yakazara nemakore sekuwedzera mukaka, mimwe yaiva chena semukaka, mimwe yaiva yero, uye mimwe yaiva yakajeka uye yakajeka. Kana uchida kugadzirisa, gadzirisa kubva pane zvataurwa pamusoro apa. Dzimwe nguva acetic acid inogona kukanganisa zvakanyanya kufambiswa kwechiedza. Zvakanakisa kushandisa acetic acid mushure mekusanganiswa. Chinonyanya kukosha ndechekuti reaction inomutswa zvakaenzana here uye kana system ratio yakagadzikana (zvimwe zvinhu zvine hunyoro uye zviri mukati hazvina kugadzikana, senge zvinonyungudutsa zvakare). Kutaura zvazviri, pane zvinhu zvakawanda zviri kuitika. Nekugadzikana kwemidziyo uye mashandiro evashandisi vakadzidziswa zvakanaka, zvigadzirwa zvinogadzirwa zvinofanirwa kunge zvakagadzikana zvikuru. Kufambiswa kwechiedza hakuzopfuuri huwandu hwe±2%, uye kufanana kwenzvimbo dzemapoka anotsiva kunofanirwa kudzorwa zvakanaka. Panzvimbo pekufanana, kufambiswa kwechiedza kwaizova kwakanaka.
